- Abstract
Perfluorinated compounds, especially Perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS), are widely detected in water environments in China. Considering the potential health risks of drinking water exposure routes, PFOA and PFOS have been added to the water quality reference index of the newly issued "Standards for Drinking Water Quality (GB5749-2022)", with limit values of 40 and 80 ng/L, respectively. This study analyzed and discussed the relevant technical contents for determining the limits of the hygiene standard, including the environmental existence level and exposure status of PFOA and PFOS, health effects, derivation of safety reference values, and determination of hygiene standard limits. It also proposed prospects for the future direction of formulating drinking water standards.

- Abstract
The usage of vinyl chloride and trichloroethylene in China has been increasing year by year, and they have been detected in both drinking water and environmental water, making them important environmental pollutants. Based on the latest research results on the health effects of vinyl chloride and trichloroethylene, the newly issued, "Standards for Drinking Water Quality (GB5749-2022)" in China has adjusted the standard limit of vinyl chloride from 0.005 mg/L to 0.001 mg/L and the standard limit of trichloroethylene from 0.07 mg/L to 0.02 mg/L. This article analyzed and discussed the relevant technical contents for determining the above standard limits, including the levels and exposure conditions of vinyl chloride and trichloroethylene in the water environment, health effects, derivation of safety reference values, and determination of hygiene standard limits. Suggestions were also made for the implementation of this standard.

- Abstract
The study investigated the clinical value of fluorescence cholangiography using indocyanine green (ICG) in laparoscopic cholecystectomy (LC) and laparoscopic common bile duct exploration (LCBDE) in preventing bile duct injury (BDI) and detecting bile leakage. A total of 300 patients who underwent fluorescent navigation LC and LCBDE in the Second Department of General Surgery, Shengjing Hospital Affiliated to China Medical University from June 2020 to September 2022 were selected as the research objects for observation and analysis. There were 114 males and 186 females, and aged (50.7±14.0) years with the body mass index (BMI) of (23.6±1.6) kg/m². All 300 cases of fluorescence navigation surgery were successfully completed, of which 5 patients received fluorescence-guided LCBDE and primary suture. The results showed that the application of fluorescence cholangiography with ICG can effectively avoid and detect the occurrence of BDI and bile leakage. Meanwhile, it is reasonable to hypothesize that ICG can be used for rapid localization and the final check to prevent the recurrence of bile leakage when bile leakage is suspected in the second operation.

- Abstract
Objective: To analyze the prevalence and the risk factors of fungal sepsis in 25 neonatal intensive care units (NICU) among preterm infants in China, and to provide a basis for preventive strategies of fungal sepsis. Methods: This was a second-analysis of the data from the "reduction of infection in neonatal intensive care units using the evidence-based practice for improving quality" study. The current status of fungal sepsis of the 24 731 preterm infants with the gestational age of <34
+0 weeks, who were admitted to 25 participating NICU within 7 days of birth between May 2015 and April 2018 were retrospectively analyzed. These preterm infants were divided into the fungal sepsis group and the without fungal sepsis group according to whether they developed fungal sepsis to analyze the incidences and the microbiology of fungal sepsis. Chi-square test was used to compare the incidences of fungal sepsis in preterm infants with different gestational ages and birth weights and in different NICU. Multivariate Logistic regression analysis was used to study the outcomes of preterm infants with fungal sepsis, which were further compared with those of preterm infants without fungal sepsis. The 144 preterm infants in the fungal sepsis group were matched with 288 preterm infants in the non-fungal sepsis group by propensity score-matched method. Univariate and multivariate Logistic regression analysis were used to analyze the risk factors of fungal sepsis. Results: In all, 166 (0.7%) of the 24 731 preterm infants developed fungal sepsis, with the gestational age of (29.7±2.0) weeks and the birth weight of (1 300±293) g. The incidence of fungal sepsis increased with decreasing gestational age and birth weight (both P <0.001). The preterm infants with gestational age of <32 weeks accounted for 87.3% (145/166). The incidence of fungal sepsis was 1.0% (117/11 438) in very preterm infants and 2.0% (28/1 401) in extremely preterm infants, and was 1.3% (103/8 060) in very low birth weight infants and 1.7% (21/1 211) in extremely low birth weight infants, respectively. There was no fungal sepsis in 3 NICU, and the incidences in the other 22 NICU ranged from 0.7% (10/1 397) to 2.9% (21/724), with significant statistical difference ( P <0.001). The pathogens were mainly Candida (150/166, 90.4%), including 59 cases of Candida albicans and 91 cases of non-Candida albicans , of which Candida parapsilosis was the most common (41 cases). Fungal sepsis was independently associated with increased risk of moderate to severe bronchopulmonary dysplasia (BPD) (adjusted OR 1.52, 95% CI 1.04-2.22, P= 0.030) and severe retinopathy of prematurity (ROP) (adjusted OR 2.55, 95% CI 1.12-5.80, P= 0.025). Previous broad spectrum antibiotics exposure (adjusted OR= 2.50, 95% CI 1.50-4.17, P< 0.001), prolonged use of central line (adjusted OR= 1.05, 95% CI 1.03-1.08, P< 0.001) and previous total parenteral nutrition (TPN) duration (adjusted OR= 1.04, 95% CI 1.02-1.06, P< 0.001) were all independently associated with increasing risk of fungal sepsis. Conclusions: Candida albicans are the main pathogens of fungal sepsis among preterm infants in Chinese NICU. Preterm infants with fungal sepsis are at increased risk of moderate to severe BPD and severe ROP. Previous broad spectrum antibiotics exposure, prolonged use of central line and prolonged duration of TPN will increase the risk of fungal sepsis. Ongoing initiatives are needed to reduce fungal sepsis based on these risk factors.Candida parapsilosis are the main pathogens of fungal sepsis among preterm infants in Chinese NICU.

- Abstract
Objective: To analyze the pollution status and influencing factors of Legionella pneumophila in a secondary water supply facility in a city. Methods: From June to August 2020, a survey on the level of Legionella pneumophila in secondary water supply unit was carried out in a city in northern China, and 304 sets of secondary water supply facilities were included in the study. A total of 760 water samples were collected from the inlet and outlet water of the secondary water supply facilities and some water samples in the water tank were collected for the detection of Legionella pneumophila , standard plate-count bacteria and related physical and chemical indicators. Through questionnaire survey, the basic information of secondary water supply facilities and daily management of water quality were collected. Multivariate logistic regression model was used to analyze the influencing factors of Legionella pneumophila contamination. Results: Among 304 sets of secondary water supply facilities, most of them were located in residential buildings [57.24% (174/304)]. High and low water tank water supply, low water tank variable frequency conversion water supply and non-negative pressure water supply accounted for 26.6% (81/304), 36.8% (112/304) and 36.5% (111/304), respectively. About 25.7% of facilities (78/304) were positive for Legionella pneumophila . Among them, the positive rates of Legionella pneumophila in high and low water tank water supply, low water tank variable frequency conversion water supply and non-negative pressure water supply facilities were 38.3% (31/81), 29.5% (33/112) and 12.6% (14/111), respectively. The results of multivariate logistic regression model analysis showed that the disinfectant residue could reduce the risk of Legionella pneumophila contamination in water samples, and the OR (95% CI ) value was 0.083 (0.022-0.317). The increase of the standard plate-count bacteria and conductivity might increase the risk of Legionella pneumophila contamination in water samples. The OR (95% CI ) values were 3.160 (1.667-5.99) and 1.004 (1.001-1.006), respectively. Compared with the non-negative pressure water supply, the risk of Legionella pneumophila contamination of secondary water supply facilities was increased by water supply from high and low water tanks and variable frequency conversion water supply from low water tanks, with OR (95% CI ) values of 4.296 (2.096-8.803) and 2.894 (1.449-5.782), respectively. Conclusion: The positive rate of Legionella pneumophila in secondary water supply in the study city is high. Disinfectant residue, conductivity and method of water supply are associated with the positive rate of Legionella pneumophila .

- Abstract
Objective: To analyze the impact of cancer on the recurrence rate of atrial fibrillation (AF) after AF radiofrequency ablation and further evaluate the feasibility of radiofrequency ablation therapy in cancer patients with AF. Methods: This study was a single-center, retrospective study. Cancer patients with AF undergoing radiofrequency ablation for the first time in the First Affiliated Hospital of Dalian Medical University from May 30, 2008 to September 30, 2018 were included (cancer group). AF patients without cancer undergoing radiofrequency ablation for the first time during the same period served as non-cancer group. Clinical data including age, gender, past history, cancer and AF-related parameters, etc. were analyzed. Patients were followed up after radiofrequency ablation. The primary endpoints were AF recurrence or all-cause death. Kaplan-Meier survival analysis was used to analyze the effect of cancers on the recurrence after AF ablation. The multivariate cox regression analysis was further applied to correct for other confounding factors to analyze whether the impact of cancers on the recurrence of atrial fibrillation was statistically significant. Results: A total of 90 patients were enrolled, there were 30 patients in the cancer group (mean age (64.8±6.6) years, 16 (53.3%) males) and 60 patients in the non-cancer group (mean age (63.6±6.2) years, 32 (53.3%) males). Clinical data, such as age, gender, and cancer treatment, were similar between the two groups. During an average follow-up period of (328.7±110.2) days, there were 6 AF recurrences (recurrence rate 20.0%) in the cancer group, and 17 AF recurrences (recurrence rate 28.3%) in the control group. AF recurrence rate was similar between the two groups ( P >0.05). During the follow-up period, there was no all-cause death in the two groups. Kaplan-Meier survival analysis showed that cancer was not related to AF recurrence after radiofrequency ablation ( P = 0.383). After adjusting for other confounding factors, the multivariate Cox regression analysis showed that cancer was not an independent predictor of AF recurrence after radiofrequency ablation ( HR =0.508, 95% CI : 0.192-1.342, P = 0.172). Conclusions: The combination of cancer has no impact on the recurrence of AF after radiofrequency ablation. For cancer patients with AF, radiofrequency ablation therapy can be considered as a feasible heart rhythm control treatment strategy.

- Abstract
Objective: To identify the factors associated with successful transrectal specimen extraction after laparoscopic rectal cancer resection. Methods: A retrospective case-control study was conducted. Clinical data of rectal cancer patients who did or did not successfully undergo transrectal specimen extraction in Shanghai East Hospital between January 2017 and December 2017 were retrieved through the rectal cancer database of Shanghai East Hospital. Case inclusion criteria: (1) tumor size ≤7 cm by pelvic MRI; (2) body mass index (BMI)≤ 30 kg/m(2); (3) no history of neoadjuvant chemoradiotherapy; (4) no anal stenosis. Clinical data including age, gender, BMI, tumor obstruction, distance from tumor to anal verge, history of abdominal operation, maximal diameter of tumor and width of mesorectum in the anteroposterior dimension measured by pelvic MRI, etc. were collected. The χ(2) test was used to perform univariate analysis. Multivariate logistic regression was used to identify factors affecting transrectal specimen extraction. Results: A total of 208 patients were included in the analysis. Of 208 patients, 132 were men and 76 were women; mean age was (63±11) years old and median tumor size was 3.8 (IQR, 3.0 to 5.0) cm. Sixty-six (31.7%) patients completed transrectal specimen extraction successfully. Univariate analysis showed that patients who completed transrectal specimen extraction were more likely to have a lower BMI (χ(2)=7.420, P =0.006), be free from malignant obstruction (χ(2)=8.972, P =0.003), have a shorter distance from tumor to the anal verge (<5.0 cm) (χ(2)=14.960, P <0.001), a smaller tumor size (≤5.0 cm) (χ(2)=18.495, P <0.001) and a thinner mesorectum in the anteroposterior dimension (≤6.0 cm) (χ(2)=34.612, P <0.001) than those who failed to perform transrectal specimen extraction. Gender, age or history of abdominal operation were not associated with the successful extraction (all P >0.05). Multivariate analysis revealed that BMI ≤25.0 kg/m(2) (OR=2.32, 95% CI: 1.06 to 5.06, P =0.034), free from malignant obstruction (OR=3.01, 95% CI: 1.82 to 6.69, P <0.001), the distance from tumor to the anal verge <5.0 cm (OR=3.73, 95% CI: 1.22 to 11.43, P =0.021), tumor size ≤ 5.0 cm (OR=4.43, 95% CI: 1.39 to 14.09, P =0.012), and the anteroposterior width of mesorectum ≤ 6.0 cm (OR=4.30, 95% CI: 2.02 to 9.18, P <0.001) were independent protective factors for successful transrectal specimen extraction. Conclusion: Preoperative assessment of BMI, malignant obstruction, distance from tumor to the anal verge, tumor size and anteroposterior width of mesorectum is beneficial to choose appropriate patients with rectal cancer to undergo transrectal specimen extraction.

- Abstract
Objective: To explore the feasibility and effectiveness of the two-point traction with guidewire method to improve the safety of percutaneous transhepatic sinus tract dilation. Methods: The clinical data of 18 patients underwent the two-point traction guided by percutaneous transhepatic sinus dilation between January 2013 and July 2017 in Shengjing Hospital of China Medical University were analyzed retrospectively. The operation time, volume of intraoperative blood loss and postoperative complications were recorded. Results: All of the 18 patients were treated successfully. The mean size of the percutaneous transhepatic sinus tract was (18.6±2.3) Fr. The operation time was 15-45 min, with an average of 30 minutes, and the average intraoperative blood loss was about 11.7 ml. The incidence of postoperative complications was 22.2% (4/18), including cholangitis in 3 patients, pancreatitis in 1 case. All the complications were relieved after symptomatic treatment, no severe complications (biliary tract perforation or severe haemorrhage) occurred. A total of (3.3 ± 2.6) times cholangioscopic explorations for stone extraction were performed, with a overall clearance rate of 64.7% (11/17). Conclusions: From the results of limited patient data in this group, the two-point traction with guidewire can provide the exact guidance for percutaneous transhepatic sinus tract dilation, which is effective and easily conducted, but still need further clinical study to confirm.

- Abstract
Objective: To describe the clinical features of hyper-IgE syndrome (HIES), with emphasis on refractory pulmonary cystic lesions as the initial presentation in adulthood. Methods: A case of HIES presenting with pulmonary cystic lesions in an adult patient was retrospectively analyzed. We used "hyper-IgE syndrome" as the Chinese keywords, "hyper-IgE syndrome, China" as the English keywords to retrieve the literature from Wanfang database/CNKI database and Pubmed database until April 2016. The clinical data were pooled and analyzed. Results: A 19 year old female patient was admitted to our hospital because of recurrent cough and expectoration as the chief complaint. Physical examination revealed broad nasal bridge and scoliosis, and chest CT showed gradually enlarged and increased cystic lesions. Laboratory studies demonstrated significantly increased blood eosinophils and serum level of total IgE, together with a definite chemotactic dysfunction of neutrophils. A further detection of STAT3 mutation was negative. The diagnosis of HIES was made and antibiotic treatment resulted in disease remission. Literature review found 45 reports including 37 in Chinese and 11 in English. Eight cases of adult HIES were reported, and all the patients were male, aging 18 to 31 years. Prolonged disease course, recurrent infection and formation of cystic lesions in the lungs were important features of HIES. Early diagnosis and treatment with specific antibiotics were important for improving outcome of the patients. Conclusion: Refractory pulmonary cystic lesions can be the initial presentation in adult HIES. Understanding of the clinical characteristics of HIES will be helpful to avoid misdiagnosis and improve prognosis.

- Abstract
Objective: To investigate the mechanism of CD34
+ progenitor cell differentiation in rat by observing the change relations between the eosinophils (EOS) and the content of Eotaxin and IL-5 in blood and the CD34+ /CCR3+ , CD34+ /IL-5Rα+ in bone marrow after occupational asthma (OA) model rats are simulated, and to observe the effect of WTKYD Trraitional Chinese Medicine intervention. Methods: A total of 40 healthy male SD model rats (200~250 g weight) were randomly divided into model contrast Group, prednisone acetate intervention Group, WTKYD+1/2 prednisone acetate intervention Group and WTKYD intervention Group, 10 in each group, and set a Group for blank contrast. Give them saline (20 ml/kg) , prednisone acetate (8.22 mg/kg) , WTKYD (20g/kg) +1/2 prednisone acetate (4.11 mg/kg) and WTKYD (20 g/kg) intervention respectively. By means of cell count, immunohistochemical, ELISA, flow cytometry technique, situ hybridization and so on, to observe EOS and the expression of Eotaxin in lung tissue, the EOS in peripheral blood, the content of Eotaxin and IL-5 in blood as well as the expression of CD34+ /CCR3+ and CD34+ /IL-5Ra+ in bone marrow respectively. Results: The number of EOS, the content of Eotaxin and IL-5, the expression of CD34+ /CCR3+ and CD34+ /IL-5Ra+ in Model Contrast Group were higher in Blank Contrast Group, the difference was statistically significant ( P <0.01) , while they were lower in medical intervention Groups when comparing to Model Contrast Group, the difference was statistically significant ( P <0.01 or P <0.05) , and the above items in WTKYD+1/2 Prednisone Acetate Intervention Group were even lower than in Prednisone Acetate Intervention Group and WTKYD Intervention Group, the difference was statistically significant ( P <0.05). EOS in lung tissue is highly positive related to the content of Eotaxin and IL-5 in peripheral blood as well as the expression of CD34+ /CCR3 and CD34+ /IL-5Rα in bone marrow (0.9666、0.9829、0.9142, 0.8874). Conclusion: The increase of internal EOS in lung tissue is related to the up-regulated expression of CD34+ /CCR3+ and CD34+ /IL-5Ra+ in bone marrow after antigens in Occupational Asthma model rats are stimulated. Through down-regulating it's expression to restrain the differentiation of CD34+ progenitor cells towards EOS, meanwhile, the collaboration of WTKYD and prednisone acetate possess a certain synergistic action.- Published

- Abstract
Objective: To discuss the preliminary experience of single incision laparoscopic colorectal surgery. Methods: The clinical data and surgical outcomes of 104 selected patients who underwent single incision laparoscopic colorectal surgery in the 2
nd Department of General Surgery, Shengjing Hospital of China Medical University from January 2010 to September 2015 were retrospectively analyzed. There were 62 male and 42 female patients, aging from 21 to 87 years with a mean of (61±12) years. Eighty-five patients were diagnosed with malignancy while the rest 19 cases were benign diseases. All the procedures were performed by the same surgeon using the rigid laparoscopic instruments. Surgical and oncological outcomes were analyzed in 4 kinds of procedures which are over 5 cases respectively, including low anterior resection, abdominoperineal resection, radical right colon resection and radical sigmoidectomy. Results: Single incision laparoscopic colorectal surgery was performed in 104 selected patients and was successfully managed in 99 cases with a total conversion rate of 4.8%. Radical procedures for malignancy in cases with the number of patients more than 5 were performed for 74 cases. For low anterior resection, 35 cases with an average surgical time of (191±57) minutes, average estimated blood loss of (117±72) ml and average number of harvested lymph nodes of 14.6±1.1. For abdominoperineal resection, 9 cases with an average surgical time of (226±54) minutes, average estimated blood loss of (194±95) ml and average number of harvested lymph nodes of 14.1±1.5. For radical right colon resection, 16 cases with an average surgical time of (222±62) minutes, average estimated blood loss of (142±68) ml and average number of harvested lymph nodes of 15.4±2.4. For radical sigmoidectomy, 14 cases with an average surgical time of (159±32) minutes, average estimated blood loss of (94±33) ml and average number of harvested lymph nodes of 13.9±1.5. The overall intraoperative complication rate was 2.7% (2 cases) and postoperative complication rate was 8.1% (6 cases) in these 74 cases. Conclusion: Single incision laparoscopic colorectal surgery is safe and feasible with acceptable surgical outcomes and cosmetic benefits in the hands of skilled laparoscopic surgeon in well-selected patients.- Published
