- Abstract
Objective: To compare the clinical outcomes of posterior maxillary implant surgery when using the regular transalveolar approach or with the crestal approach-sinus (CAS-KIT), a device for maxillary sinus membrane elevation by the crestal approach using a special drilling system and hydraulic pressure. Methods: In this retrospective study 887 patients during Jan 2012 to July 2015 in Hangzhou Dental Hospital with underwent either regular transalveolar approach or CAS-KIT approach for maxillary augmentation; whereas 11 patients dropped out for the reason of serious membrane perforations. Totally, 876 patients with 1 204 plants, placed immediately after transalveolar maxillary augmentation, were included in this study. The data analysis was performed by radiological measures to assess the changes in height of maxillary sinus floor after the transalveolar augmentation at different time points. In addition, the complications after surgery, failure rates, osseointegration condition and the performance of rehabilitation were evaluated as well. Results: Five hundred and three patients were experienced with regular transalveolar approach, and 7 patients were drop out for the serious membrane perforations. Thus, 496 patients received 653 implants in this group; the average lifted range in maxillary sinus floor height changes was (4.08±3.45) mm. The complications were minor membrane perforations during procedure in 64 patients, postoperative maxillary sinus infection happening in 2 patients and 13 patients experienced rehabilitation failure. Three hundred and eighty-four patients had CAS-KIT approach with 4 patients dropped out. Three hundred and eighty patients get 551 implants with the mean lifted range of (8.36±4.07) mm in maxillary sinus floor height changes. Minor membrane perforations during procedure occurred in 31 people and 2 got postoperative maxillary sinus infection. The 4 year overall survival rate of 1 204 implants was 97.26%, with four implants fell off after 3 months of rehabilitation and one implant occurred after one year of rehabilitation. Conclusions: The regular transalveolar sinus lift technique is easier and time saving, but the compromised lifting range in maxillary sinus floor height and the comparatively high occurrence of intraoperative membrane perforations should be concerned. Using CAS-KIT could be an alternative method to perform maxillary sinus augmentation with a reduced incidence of complications. There was no statistically difference in implant failure rates and incidence of postoperative maxillary sinus infection between two groups.

- Abstract
Objective: To investigate the clinical manifestations and genetic features of a child with Bainbridge-Ropers syndrome caused by ASXL3 gene variation and review the literature. Methods: Clinical data and genetic features were collected and analyzed from a child with Bainbridge-Ropers syndrome who was diagnosed in Bao'an Maternity and Child Health Hospital in November 2016. "ASXL3" and "Bainbridge-Ropers" were used as key words to search at China National Knowledge Infrastructure, Wangfang Data Knowledge Service Platform, PubMed and Human Gene Mutation Database up to June 2017. Results: A 2(9/12) years old girl was presented with psychomotor retardation, feeding difficulty, hypotonia and specific craniofacial phenotype. She showed severe growth retardation (height: 84 cm, body weight: 8.0 kg (both were less than 3(rd) percentile rank of the children at the same age) and head circumference: 46 cm(=3rd percentile rank)), without obvious abnormalities in laboratory tests and neuroimaging tests. A de novo heterozygous nonsense variation: c.3349C>T(p.R1117*) in ASXL3 gene was identified by the whole exome sequencing, and the novel variation was classified into pathologic variant based on Standards and guidelines for the interpretation of sequence variants from ACMG. According to literature retrieval, no Chinese cases with ASXL3 variation had been reported. Totally 28 cases including the present girl harboring ASXL3 variations with detailed clinical information were reported. Thirty-one variations in ASXL3 gene were involved, including 1 missense variation and 30 loss of function variations, which were all de novo variations. Conclusions: The clinical features of Bainbridge-Ropers syndrome include severe psychomotor retardation, feeding difficulties, hypotonia and specific facial features. The heterozygous nonsense variation in ASXL3 gene is the cause of the patient. All the pathogenic variations in ASXL3 gene are de novo and loss of function variations.

- Abstract
To establish the experts consensus on the right heart function management in critically ill patients. The panel of consensus was composed of 30 experts in critical care medicine who are all members of Critical Hemodynamic Therapy Collaboration Group (CHTC Group). Each statement was assessed based on the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) principle. Then the Delphi method was adopted by 52 experts to reassess all the statements. (1) Right heart function is prone to be affected in critically illness, which will result in a auto-exaggerated vicious cycle. (2) Right heart function management is a key step of the hemodynamic therapy in critically ill patients. (3) Fluid resuscitation means the process of fluid therapy through rapid adjustment of intravascular volume aiming to improve tissue perfusion. Reversed fluid resuscitation means reducing volume. (4) The right ventricle afterload should be taken into consideration when using stroke volume variation (SVV) or pulse pressure variation (PPV) to assess fluid responsiveness.(5)Volume overload alone could lead to septal displacement and damage the diastolic function of the left ventricle. (6) The Starling curve of the right ventricle is not the same as the one applied to the left ventricle,the judgement of the different states for the right ventricle is the key of volume management. (7) The alteration of right heart function has its own characteristics, volume assessment and adjustment is an important part of the treatment of right ventricular dysfunction (8) Right ventricular enlargement is the prerequisite for increased cardiac output during reversed fluid resuscitation; Nonetheless, right heart enlargement does not mandate reversed fluid resuscitation.(9)Increased pulmonary vascular resistance induced by a variety of factors could affect right heart function by obstructing the blood flow. (10) When pulmonary hypertension was detected in clinical scenario, the differentiation of critical care-related pulmonary hypertension should be a priority. (11) Attention should be paid to the change of right heart function before and after implementation of mechanical ventilation and adjustment of ventilator parameter. (12) The pulmonary arterial pressure should be monitored timingly when dealing with critical care-related pulmonary hypertension accompanied with circulatory failure.(13) The elevation of pulmonary aterial pressure should be taken into account in critical patients with acute right heart dysfunction. (14) Prone position ventilation is an important measure to reduce pulmonary vascular resistance when treating acute respiratory distress syndrome patients accompanied with acute cor pulmonale. (15) Attention should be paid to right ventricle-pulmonary artery coupling during the management of right heart function. (16) Right ventricular diastolic function is more prone to be affected in critically ill patients, the application of critical ultrasound is more conducive to quantitative assessment of right ventricular diastolic function. (17) As one of the parameters to assess the filling pressure of right heart, central venous pressure can be used to assess right heart diastolic function. (18). The early and prominent manifestation of non-focal cardiac tamponade is right ventricular diastolic involvement, the elevated right atrial pressure should be noticed. (19) The effect of increased intrathoracic pressure on right heart diastolic function should be valued. (20) Ttricuspid annular plane systolic excursion (TAPSE) is an important parameter that reflects right ventricular systolic function, and it is recommended as a general indicator of critically ill patient. (21) Circulation management with right heart protection as the core strategy is the key point of the treatment of acute respiratory distress syndrome. (22) Right heart function involvement after cardiac surgery is very common and should be highly valued. (23) Right ventricular dysfunction should not be considered as a routine excuse for maintaining higher central venous pressure. (24) When left ventricular dilation, attention should be paid to the effect of left ventricle on right ventricular diastolic function. (25) The impact of left ventricular function should be excluded when the contractility of the right ventricle is decreased. (26) When the right heart load increases acutely, the shunt between the left and right heart should be monitored. (27) Attention should be paid to the increase of central venous pressure caused by right ventricular dysfunction and its influence on microcirculation blood flow. (28) When the vasoactive drugs was used to reduce the pressure of pulmonary circulation, different effects on pulmonary and systemic circulation should be evaluated. (29) Right atrial pressure is an important factor affecting venous return. Attention should be paid to the influence of the pressure composition of the right atrium on the venous return. (30) Attention should be paid to the role of the right ventricle in the acute pulmonary edema. (31) Monitoring the difference between the mean systemic filling pressure and the right atrial pressure is helpful to determine whether the infusion increases the venous return. (32) Venous return resistance is often considered to be a insignificant factor that affects venous return, but attention should be paid to the effect of the specific pathophysiological status, such as intrathoracic hypertension, intra-abdominal hypertension and so on. Consensus can promote right heart function management in critically ill patients, optimize hemodynamic therapy, and even affect prognosis.

- Abstract
Transthyretin (TTR)-related familial amyloid polyneuropathy (FAP), which is caused by mutant TTR, is a rare but fatal autosomal dominant disease. TTR is synthesized by the liver (95%) , the choroid plexus of the brain and the retinal pigment epithelium. FAP leads to peripheral neuropathy, and the main ocular manifestations are vitreous opacity (yellowish cotton-like), secondary glaucoma and keratoconjunctivitis sicca. Liver transplantation has proven to be the most effective treatment for TTR-FAP. Nowadays, tafamidis is the only drug approved for TTR-FAP (early stage). However, neither liver transplantation nor tafamidis is capable to halt the progression of ocular involvement. Panretinal photocoagulation could damage the retinal pigment epithelium, and thus prevent the progression. Recent investigations on TTR-FAP and its ocular involvement are reviewed in this article.

- Abstract
We treated five, three steroid resistant and 2 steroid dependent nephrotic syndrome with oral cyclosporin A and prednisolone. All children received more than eight weeks course of prednisolone, and were in a critically ill status from their nephrotic syndrome and by steroid-toxic side effects. Cyclosporin A was started at 7 mg/kg/day and titrated to maintain serum level of 150-250 ng/ml. Prednisolone was given initially at a dose of 1 mg/kg/day x 1 month, subsequently at a dose of 0.4 mg/kg/day x 1 month, then 0.2 mg/kg/day x 4 months. After a total course of six months, cyclosporin A was tapered to 3.5 mg/kg/day. Prednisolone was maintained at a dose of 0.2 mg/kg/day. Renal biopsies of the 3 steroid resistant children showed membranous glomerulonephritis with focal segmental glomerulosclerosis, focal segmental glomerulosclerosis and IgM nephropathy respectively. These three cases all went into complete remission within four weeks. Among them, one case relapsed twice within one year. Renal biopsies of the two steroid dependent children showed minimal change and focal segmental glomerulosclerosis respectively. These two cases went into complete remission within three weeks sustained up to a year. Side effects of cyclosporin A were observed in one patient with gum hypertrophy and two patients with hirsutism. Other side effects were not found. After cyclosporin A treatment for one year, the renal biopsy of the relapsing patient showed no interstitial fibrosis or tubular atrophy. In conclusion, cyclosporin A was found to be effective in steroid resistant and dependent patients. The duration of cyclosporin A treatment is so far unknown. It needs further evaluation in the future.

- Abstract
Candida arthritis is extremely rare. However, there has been a steady increase in the incidence of candida arthritis during the last decade because of increasing candida infections in immunocompromised hosts, drug addicts, premature babies, and those who have received prosthetic joint operations or intraarticular injections of steroids. We report herein two cases of candida arthritis: a 27-year-old man with aplastic anemia and transfusional hemosiderosis, and a 60-year-old man with osteoarthritis who received repeated intra-articular injections of steroids. Definite diagnoses were made after repeated smear examinations of synovial fluids. In the first case, candida arthritis occurred about 2 weeks after an antecedent candidemia. Although the arthritis relapsed once due to inadequate antifungal treatment, it was finally successfully treated with systemic amphotericin B, oral ketoconazole and surgical drainage of the synovial fluid. In the second case, it took several months to make the diagnosis. The patient was also treated with amphotericin B, ketoconazole, and surgery with a satisfactory outcome. We conclude that since candida arthritis is a slow, less destructive joint infection, it can almost always be resolved. Also, late orthopedic complications can be avoided by early diagnosis and prompt treatment, including aggressive antifungal therapy, adequate drainage and necessary surgical intervention.

- Abstract
Cerebrospinal fluid eosinophilia are an uncommon finding that is most often the result of a helminthic infection of the central nervous system. Information from the recorded literature suggests the differential diagnosis of this clinical observation is relatively limited. This is a report of a girl with acute lymphoblastic leukemia who developed central nervous system relapse of leukemia following 3 years of remission. She showed marked eosinophilia in the cerebrospinal fluid 6 weeks preceding central nervous system leukemia. No cause for the eosinophilia was identified. The gradual accumulation of case reports of eosinophilia in the cerebrospinal fluid with or without blood eosinophilia in patient with leukemia suggests that this finding is of some importance.

- Abstract
In dogs inflicted third-degree burns of 25% TBSA the hemodynamic changes were observed with resuscitation with whole blood (group A) or balanced saline solution (group B). The results showed that there were significant differences in time and degree of recovery between two groups. In group A, the recovery of cardiac index (CI) began after 18 hr of resuscitation, and it was delayed to 22 hr; in group B, 24 hr after the injury. Two groups showed significant differences in CI. The recovery in CI related mainly to stroke index. Moreover, group B animals showed higher pulmonary arterial pressure after injury. There was significant difference between the level at 48 hr and the pre-injury level. It could be concluded that resuscitation with whole blood did give more satisfactory resuscitation than pure crystalloid.

- Abstract
The urinary tract is a common site for bacterial infection in childhood. The most important aspect of urinary tract infection in childhood is that it can lead to severe and progressive renal disease. From March 1983 to March 1987, 63 cases of suspected urinary tract infection were collected in Taichung VGH. Among them only 24 cases reached our diagnostic criteria. Eight cases were within 2 years old, which all are male. Sixteen cases were beyond 2 years old, which the ratio of male to female is 1:1. Eighteen cases presented pyuria. Ten cases had recurrent infections, among which eight cases had urinary abnormalities. The most common pathogenic organism was E. coli (44%), then Proteus (24%), Klebsiella (16%), Pseudomonas (12%). The antibiotics sensitivity test revealed 95.7% were sensitive to gentamicin and amikacin, 81% to cephalothin, 56. 5% to sulfamethoxazole-trimethoprim. Imaging studies revealed nine cases (37.5%) with urinary tract abnormalities, including vesicoureteral refluxes 6 cases, right multicystic kidney with left vesicoureteral reflux 1 case, horse-shoe kidney 1 case, atonic bladder 1 case. The ratio of male to female is 2:1. All seven cases of severe vesicoureteral refluxes received surgery. One case developed post-operative ureteral stricture. One case occurred unilateral chronic renal parenchymal disease one year later. Others were free of reflux and reinfection of urinary tract.

- Abstract
Sepsis remains a significant cause of morbidity and mortality in newborn infants. From January 1983 to April 1988, 166 cases of neonatal sepsis with positive blood cultures were collected at V.G.H.--Taichung. Among them 140 newborn babies were delivered at private clinic (outborn babies), 26 cases were inborn babies. Of the inborn babies, 20 cases (76.9%) were early onset sepsis (the onset of illness within 96 hours of life) and 6 cases (23.1%) were late onset sepsis (the onset of illness beyond 96 hours of life). Off the outborn babies, 64 cases (45.7%) were early onset sepsis and 76 cases (54.3%) were late onset sepsis. The Gram positive organism (51.9%) was more common than the Gram negative organism in the inborn babies, on contrary, the Gram negative organism (59.0%) was more common in the outborn babies. The most common pathogenic organism of the inborn babies was Enterococcus (22.2%) and E. coli (22.2%), followed by Pseudomonas spp (11.1%) and Staphylococcus aureus (11.1%). The most common pathogenic organism of the outborn babies was Enterococcus (17.4%), followed by E. coli (16.1%), Staphylococcus aureus (9.9%) and Klebsiella spp (8.1%). The antibiotics sensitivity tests to the pathogens didn't show any significant difference between these two group babies. In this clinical study, we found that the first choices of antibiotics were ampicillin plus aminoglycosides. The clinical symptoms and signs were nonspecific. The most common findings were lethargy, fever, hypothermia and poor feeding. Of the inborn babies, 17 cases (65.4%) had the predisposing factor(s). Of the outborn babies, 42 cases (30%) had the predisposing factor(s).(ABSTRACT TRUNCATED AT 250 WORDS)

- Abstract
The alpha-amylase of Bacillus stearothermophilus Q8, previously isolated in our laboratory, was purified by ammonium sulfate precipitation and CM-sephadex chromatography. The activity the of partial purified alpha-amylase was to be protected by bovine serum albumin Ca2+ and Mg2+. The enzyme showed 100% activity at pH 9.0; 98%, at pH 8.0 and 41%; at pH 10.0. It expressed optimal reaction temperature at 90 degrees C, 81% of the activities remained at 100 degrees C. After 15 min incubation at 100 degrees C with the addition of 10 mM Ca2+, the enzyme only retained 67% activity. The enzyme, however, retained 10% of the maximal activity after 2 h incubation at 90 degrees C, in the absence of substrate and with the addition of Ca2+. Of cations, Na+ at 0.1 and 1 mM, Mn2+ at 0.1 mM showed stimulatory effect; of anions OH-Cl-I-HCO3-NO2-N3- at 10 mM showed stimulatory effect. Addition of urea and KMnO4 resulted in the loss of enzyme activities; however, lower concentration of SDS and Tween 80 afforded protection of the enzyme activities. Galactose and maltose were non-inhibitory for the enzyme activities, while, fructose, mannose, xylose and lactose were slightly inhibitory. The relative hydrolysis sequence of polysaccharides were amylose greater than soluble starch = corn starch greater than glycogen.

- Abstract
Between September 1986 and April 1988, five low birth weight infants weighing 950 gm to 2250 gm required acute peritoneal dialysis due to acute anuric renal failure. Severe hyaline membrane disease was the most common explanation for acute renal failure. All infants had severe electrolytes imbalance and fluid retention with generalized edema, which increased ventilation requirements and severely limited fluid intake. The volume of each exchange varied between 10-20 ml/kg. Four of five infants had good ultrafiltration (3.52 +/- 2.43 ml/kg/hr, mean +/- SD). Ultrafiltration was not achieved in one due to poor peripheral perfusion. Electrolytes imbalance were corrected in all patients. Although four infants died, one case given up further care after renal failure had improved, and one died of septic shock after renal function had recovered. Only one infant survived with complete recovery of renal function. We believe that early dialysis is likely to reduce both morbidity and mortality of acute renal failure in low birth weight infants.
