Background The filtering surgery is the main method of treating glaucoma.Fibrosis of filtering bleb is a key cause of failure of operation.The study about application of anti-scaring drug in filtering surgery is a hotspot.Objective Present study was to investigate the anti-scaring effect of paclitaxel aher trabeculectomy.Methods Thirty-two adult clean domestic rabbits underwent standardized trabeculectomy and randomly divided into 4 groups.Normal saline solution was used beneath the scleral flap during trabeculectomy for 3 minutes in 16 eyes of 8 rabbits as controls.0.3 g/L mitomycin C,0.2 g/L paclitaxel or 0.3 g/L paclitaxel was administered at the same way respectively in other 3 groups.Intraocular pressure (IOP) was measured,and eye numbers with function blebs were compared among 4 groups at the 4th,7th,14th and 28th day after surgery.The opening of filtration tunnel and the number of inflammatory cells were observed by hematoxylin and eosin staining,and proliferation of new collagen fibers was evaluated by Masson trichrome method.This study complied with the Regulations for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission(version 1988). Results No significant differences were found in the change of lOP among 4 groups before operation(F=0.54,P=0.83)and the 4th day aher operation(F=0.57,P=0.87).The IOP value was statistically lower in 0.3 g/L mitomycin C group,0.2 g/L paclitaxel group and 0.3 s/L paelitaxel group than the normal saline solution group(P＜0.05)with the lowest value in 0.3 s/L paclitaxel group in 7,14,28 days after operation(P＜0.05).Functional filtering bleb was seen in all the rabbit eyes in the 4th day after operation.In 7,14,28 days after operation,the number of eyes with functional bleb wag evidently more in 0.3 g/L mitomycin C group,0.2 g/L paclitaxel group and 0.3 g/L paclitaxel group compared with normal saline group(P＜0.05).The histological examination showed that the infiltration of inflammatory cells in filtering tunnel was much more obvious in normal saline solution group than the other groups with the most mild response in 0.3 g/L paclitaxel group.Masson trichrome revealed that proliferation of new collagen fibers in 0.3 g/L paclitaxel group was significantly decreased in comparison with those in other three groups at the 4th,7th,14th and 28th day after surgery(all P＜0.05). Conclusion Paclitaxel can inhibit the inflammatory response and collagen fibrosis and therefore open the filtering tunnel after it be used topically during the glaucoma trabeculectomy.

OBJECTIVETo study the application of digitized three-dimensional (3D) image reconstruction in living-related kidney transplantation.

METHODSThe image data of 16-slice spiral CT in 5 cases of living-related kidney transplantation were collected to reconstruct the 3D model of the donor and recipient, which were then imported in the FreeForm Modeling System. The optimal surgical approach for each individual case was planned and simulated for verification. During the actual surgeries, the surgical findings were compared against the reconstructed model and the results of simulated surgery.

RESULTSThe 3D model clearly displayed the anatomy of the kidney and the variation of the related vessels. The optimal surgical approaches were planned through the simulated surgery. The anatomy of the kidney and the related vessels found in the actual surgeries were consistent with that displayed by the reconstructed 3D model. All the operations were completed successfully according to the surgical plan, and the patients recovered uneventfully without obvious complications.

CONCLUSIONThree-dimensional reconstruction and simulated surgery allow optimization of the surgical approaches of living-related kidney transplantation to ensure successful operation and minimize the surgical risks.

Objective The present study was conducted to identify the Vibrio cholera type and to analyze its antibiotic resistance in an epidemic of cholera in Haiyan County in 2018, which would provide the references for prevention and control of cholera. Methods Stool samples of the patient and his close contacts as well as the food and environmental samples were collected for identification of the type of Vibrio cholerae and the toxin gene. The resistance of identified Vibrio cholerae to 20 different common antibiotics were tested. Results A total of 176 samples were collected, including 101 stool samples from the case and his close contacts, 35 environmental samples and 40 food samples. Among those samples, only one strain of V. cholerae, O139, was isolated from the patient's first feces sample. It was detected as a toxin gene of ctxA positive by real-time fluorescence PCR. Antibiotic resistance test showed that the strain was sensitive to norfloxacin, levofloxacin, ciprofloxacin, cefotaxime, cephalothin, ampicillin, and amoxicillin. It was 100% resistant to tetracycline, doxycycline, neomycin, kanamycin, streptomycin, and rifampicin. Conclusion V. cholerae O139 strain with ctxA is detected in an epidemic of cholera. Norfloxacin, levofluoxacin and some other antibiotics could be used for clinical treatment and prevention. It should pay attention to this strain of V. cholera regarding the multiple drug resistance and the change of antibiotic resistance.

OBJECTIVETo appraise the value of clinical treatment of percutaneous reduction and fixation of osteoporotic fractures for the proximal humerus in a geriatric population.

METHODSPostoperation complication, mortality in hospital and within the first three months postoperation, operation time, blood transfusion requirement, the functional outcome of the shoulder had been analysed and observed in 37 cases for open and closed fixation.

RESULTSClosed reduction provided the benefit of obtaining and holding adequate reduction without the soft-tissue dissection of open reduction and internal fixation. The general complication and mortality in the first three months postoperation in the open reduction and internal fixation cases were more severe than the percutaneous cases.

CONCLUSIONSOpen operation increases the risk of the geriatric population with osteoporotic proximal humerus fracture; percutaneous reduction and fixation may be preferable.

OBJECTIVETo evaluate the role of orthotopic liver transplantation (OLT) in treatment of hepatocellular carcinoma (HCC) and the selection of recipients.

METHODSOLT was performed in 60 patients with HCC at Organ Transplantation Centre of the First Affiliated Hospital of Sun Yat-sen University between September 1993 and September 2002. Medical records were retrospectively analyzed with regard to the response to OLT and survival.

RESULTSOne-month, 1, 2, 3-year survival rate of 23 liver transplant performed from September 1993 to July 2002 were 73.9%, 60.9%, 43.5% and 29.0%, respectively. One-month, 1, 2-year survival rate of 37 liver transplant performed from August 2000 to September 2002 were 89.2%, 75.8% and 61.2%, respectively. One-month survival rate was significantly greater in the patients with a preoperative liver function of Child A or B than Child C (P < 0.05). One-month, 1, 2, 3-year survival rate of small HCC (single tumor 5 cm diameter, n = 41) were 84.2%, 76.6%, 65.6%, 65.6% and 82.9%, 63.1%, 46.7%, 37.4%, respectively. The median survival of large HCC was 18.0 months and mean survival of small HCC was 29.6 months, respectively. The recurrence rate of small HCC and large HCC were 15.8% and 27.7%, respectively. There was no significant difference between the cumulative survival of small HCC and large HCC. The quality of life of patients with long-term survival was good.

CONCLUSIONSHCC associated with cirrhosis can be effectively treated by OLT on condition that no extrahepatic spread and no vascular involvement. OLT is recommended for treatment of small HCC combined with liver cirrhosis, meanwhile, OLT performed in the partial large HCC still is reasonable at the present time.

OBJECTIVETo synthesize the complex fac-[⁹⁹(m)Tc(CO)₃(H₂O)₃](+) for labeling IgG and investigate the in vitro stability of ⁹⁹(m)Tc(CO)₃(H₂O)₃-IgG and its biodistribution in mice.

METHODSfac-[⁹⁹(m)Tc(CO)₃(H₂O)₃](+) was synthesized and its radiochemical purity determined using polyamide membrane chromatography. IgG was directly labeled with fac-[⁹⁹(m)Tc(CO)₃(H₂O)₃](+) and the labeling ratio was determined using chromatography. The stability of ⁹⁹(m)Tc(CO)₃(H₂O)₃-IgG in human serum albumin and normal saline was evaluated. ⁹⁹(m)Tc(CO)₃(H₂O)₃-IgG was injected via the tail vein into 9 mice at the dose of 3.7×10⁴ Bq/100 µl, and SPECT image was obtained at 2, 4 and 12 h after the injection. The mice were sacrificed at these time points to measure the radioactivity and calculate the %ID/g in each organ.

RESULTSFac-[⁹⁹(m)Tc(CO)₃(H₂O)₃](+) had a radiochemical purity of 82.48% and remained stable in vitro at room temperature within 4 h. The labeling ratio of ⁹⁹(m)Tc(CO)₃(H₂O)₃-IgG was 57.04% with a radiochemical purity exceeding 90%. In the solution of human serum albumin, the labeled IgG maintained a stable radiochemical purity, but in normal saline, its radiochemical purity was lowered to 20% at 24 h. After injection in mice, the labeled IgG was deposited mainly in the liver, spleen, kidneys, and the blood pool showed a sustained radioactivity.

CONCLUSION⁹⁹(m)Tc(CO)₃(H₂O)₃-IgG prepared in this study has good stability in vitro and in vivo in 24 h and shows a biodistribution pattern similar to that of IgG protein in vivo. The intermediate fac-[⁹⁹(m)Tc(CO)₃(H₂O)₃](+) can meet the experimental requirement for labeling monoclonal antibodies and polypeptides.

OBJECTIVETo explore the efficacy and mechanism of Lirukang Granule in treating hyperplasia of mammary gland (HMG).

METHODSOne hundred patients with HMG were randomly assigned to two groups, 50 in each group. The patients in the treated group were orally administered with LRKG thrice a day, one package each time, and those in the control group were given orally Rukuaixiao Tablet thrice a day, 4 tablets each time. The therapeutic course for both groups was 4 months. The clinical efficacy, pain alleviating rate, as well as changes of local sign and symptom scores were observed before and after treatment. The changes of serum estradiol (E(2)), progesterone (P), testosterone (T), follicle stimulating hormone (FSH), luteinizing hormone (LH) and prolactin (PRL) in some randomly selected patients (24 patients in the treated group and 24 in the control group) before and after treatment were measured with radioimmunoassay.

RESULTSThe total clinical efficacy in the treated group was superior to that in the control group, significant difference was shown between the two groups (P < 0.01). The cure-effective rate and total effective rate in the treated group were 70.0% and 88.0% respectively, significantly higher than those in the control group (38.0% and 64.0%) respectively (P < 0.01), and the pain alleviating rate in the treated group was also significantly higher in the former than that in the latter (88.0% vs 64.0%, P < 0.05). Moreover, the treated group showed obvious superiority in improving the patients' symptom and sign scores (P < 0.01), and abnormalities of gonadal hormone as compared with the respective items in the control group (P < 0.01).

CONCLUSIONLRKG has good efficacy in the treatment of HMG, and its mechanism may be related to the regulation on endocrine and immune function.
