AIM:To discuss the application effect of adjustable sutures in glaucoma filtering operation after trabecular resection.
METHODS: Seventy-eight cases ( 101 eyes ) suffered from glaucoma were randomly divided into two groups, observation group and control group. Thirty-nine cases ( 51 eyes ) in the observation group underwent trabeculectomy with adjustable sutures, the control group (39 cases, 50 eyes) only adopted trabeculectomy.RESULTS: Compared Preoperative IOP in two groups, the difference was not statistically significant (P>0. 05). After 6mo, IOP were decreased compared with preoperative in two groups, and that in observation group was lower than control group, the difference was statistically significant ( P < 0. 05 ). Six months after operation, there were 1 eye with shallow anterior chamber Ⅰ and 2 eyes with non- functional bleb in observation group, and the complication rate was 5. 9%. While there were of 6 eyes with shallow anterior chamber, in which 4 eyes at gradeⅠ, each one at gradeII and Ⅲ. Non-functional blebs in 5 eyes and a scleral flap adhesion complications rate in the control group was 24. 0%, significantly higher than that in the observation group, the difference was statistically significant ( P<0.01).
CONCLUSION: The adjustable sutures combined with trabeculectomy for glaucoma can significantly reduce the postoperative complications. The curative effect is exact and clinically applicable.

The microbial community structure of 4 kinds of sponges in South China Sea were revealed using culture-independent PCR- DGGE gene fingerprint technique as well as the mixed culturable microorganism. The relationship between the culturable and un-culturable microorganism was studied based on the different fingerprint profile. It was found that there is host specificity for microorganism in different sponges from the same marine area. Culture condition such as medium is an important factor for sponge-associated microbial cultivation and the culturable microorganism amount to only a little part of the total sponge-associated microorganisms.

A 35-year-old woman patient,complained of intermittent pain in the left flank for a week.Abdominal ultrasound and computed tomography scan revealed a left renal mass.Nephrectomy was performed,and a final diagnosis of adult Wilms' tumor was made based on histopathology and immunohistology.Chemotherapy was conducted for 4 times with dactinomycin D,vincristine and doxorubicin after surgery.At the time of the last recheck,the patient was alive with no evidence of disease.Adult Wilms' tumor is the exceptional malignant renal tumor.Only 1%-2% of Wilms' tumor is diagnosed in adult patients.Because of unspecific tumor symptoms in adults,the diagnosis is frequently made by histology.The diagnosis of adult Wilms' tumor is difficult to make preoperatively because diagnostic imaging only confirms the presence of a renal mass.Stage and histology are the clinical factors guiding the selection of postsurgical treatment and prognosis.Having retrospected 6 cases of adult Wilms' tumor between 1950 and 2007 and reviewed related reports,we conclude that the proper strategies of adjuvant treatment as applied to childhood Wilms' tumor patients after surgery can conspicuously improve the outcome in adult patients.

Objective To investigate the clinical application of suspended red blood cells in Liuzhou,in order to make the transfusion of blood components more reasonable and safer.Methods Retrospective data were collected from 226 patients,who had received the transfusion of 980 units of suspended red blood cells between 2000 and 2006.Results Suspended red blood cells could be used widely to different kinds of patients,and most patients benefit from the treatment.The transfusion of leuko-reduced RBC was even more effective.The age,gender,category of disease,disease severity,hemoglobin level and the amount of transfusion were the key points that affect the therapeutic effect of transfusion.Traumatic hemorrhage was another important factor.Unreasonable clinical transfusion still exists.Conclusion Transfusion of suspended red blood cells is an effective treatment.But when and how to transfuse depend on individual cases.

Objective To summarize the experience and clinical characteristics in liver re- transplantation following adult-to-adult living donor liver transplantation.Methods Due to biliary complication (2 cases),vascular complication (2 cases),chronic rejection (1 case) and hepatitis recur- rence (1 case),liver re-transplantation was performed on 6 patients through modified piggyback liver transplantation.Vascular anastomosis was performed between the hepatic arteries of donor livers and receptor abdominal aorta in 1 case,and the rest were subjected to end-to-end homonymic vascular anastomosis.Results No operative death occurred.Due to primary non-function,1 died after the ope- ration.During the follow-up period,1 had anastomotic stricture of hepatic artery after the operation and was cured by percutaneous venoplasty.The survival of the rest patients was 12,9,6,4 and 3 months respectively.Conclusion Peritoneal adhesion is the operative difficulty for liver re-transplantation following adult-to-adult living donor liver transplantation.

Objective To analyze the clinical and ultrasonic features of primary squamous cell carcinoma of the thyroid(PSCCT)and diagnostic value of ultrasonography (US) in PSCCT in order to improve the cognition of PSCCT.Methods The clinical data and ultrasonic characters of 5 patients with PSCCT confirmed by pathology post surgery were retrospectively reviewed.Results The average age of the 5 patients was 62 years (range from 46 to 79).All of 5 patients with PSCCT were presented with a painless neck mass in clinical palpation examination.Of them,2 patients had different degrees of difficulty in breathing and swallowing,2 patients had hoarseness.Four of 5 patients had died after surgery with average survival time of 9.5 months.On US,the size of lesions was large(a maximum diameter of 2.9-5.5 cm),all of 5 lesions appeared as single solid mixed-echogenicity mass including irregular lamellate marked hypoechoic region,with irregular margin and undefined boundary.Of them,2 lesions presented with lobulated,only 1 lesion exhibited microcalcification and another 4 lesions had no calcification,3 lesions exhibited a? sign of breakthrough thyroid envelope.Color Doppler flow imaging showed few blood flow (3/5) and moderate blood flow (2/5),a higher vascular resistance spectrum was detected in 4 lesions (RI 0.72-0.88).Three patients exhibited suspicious cervical lymph nodes.Conclusions The characteristic ultrasonic appearance combined with the clinical features enables a confident preoperative diagnosis of PSCCT.

The relationship between the precision of the estimated sampling variances and the number of samples was quantitatively established. It revealed that the product of the standard deviation of the estimated samplingvariance and square root of the number of samples was a constant. Monte Carlo simulation technique was employed to verify the equation. Populations with Gaussian,unifohn random and multi-nomial(taking silicon carbide material as an example) distributions were studied with satisfactory results.

Objective: Our aim was to study whether the cellular bronchoalveolar lavage fluid (BALF) profile was associated with the parameters of pulmonary function tests. Methods：Lung function tests and BAL were carried out in 18 untreated, non-smoking patients suffering from sarcoidosis and 18 normal subjects. Results：（1）Lung function tests were normal at rest in patients with sarcoidosis（P＞0.05）, the single breath carbon monoxide diffusing capacity decreased (P＜0.05)，and the small airway function decreased too (P＜0.05).（2）The percentage of lymphocytes in BALF of sarcoidosis increased comparing with the normal subjects（P＜0.01），and the ratio of CD+4 to CD+8 in BALF increased significantly in sarcoidosis（P ＜0.05）, furthermore, the increase of both the percentage of lymphocytes and the ratio of CD+4 to CD+8 in BALF of sarcoidosis were well nagatively correlated with the decrease of the percentage of DLCO (r=-0.67, P＜0.01 and r=-0.55, P＜0.05, respectively), the decrease of mid-expiratory flow at 50% of vital capacity (FEF50%) was well correlated with the increase of the percentage of lymphocytes in BALF of sarcoidosis (r=-0.54, P＜0.05). Conclusion：Pulmonary diffusing capacity（DLCO) was significently correlated with BALF lymphocyte phenotype，so was small airway function，and can act as the marker of activity of sarcoidosis.
