BACKGROUNDChemotherapy is one of the important treatment methods for advanced non-small cell lung cancer (NSCLC). The aim of this study is to evaluate the efficacy of the combination of vinorelbine (NVB) and cisplatin (DDP) in the treatment of advanced NSCLC.

METHODSForty-eight patients with stage IIIB and IV NSCLC were treated with NVB (25mg/m² ,iv,d1 and d8) and DDP (40mg/m², d1 and d2).

RESULTSThe overall response rate (RR) was 48%, median survival time was 10 months, and 1-year survival rate was 35%. The RR of patients with first-line chemotherapy was 55%, median survival time was 11 months, the RR of patients with second-line chemotherapy was 35%, median survival time was 8 months; the RR of patients with stage IIIB was 54%, median survival time was 10 months, the RR of patients with stage IV was 41%, median survival time was 9 months. The main toxicities were myelosuppression, nausea, vomiting and phlebitis.

CONCLUSIONSThe combination of NVB and DDP in the treatment of advanced NSCLC has a high response rate and tolerable side effects, which can be adopted as the first-line treatment of advanced NSCLC, or the second line treatment that still need further studies.

Objective To explore the effects and safety of hemoperfusion(HP) therapy on tetramine poisoning in infants.Methods Thirty-five infants with tetramine poisoning were divided into two groups: HP group(n=18) and non HP group(n=17).The changes of blood tetramine concentration and clinical symptom improving of both groups after the treatment were observed together with the adverse effects of HP group.Results The average blood tetramine concentration of HP group was higher than that of non HP group(342.2?333.4 vs 117.9?50.8 ?g/L,P

OBJECTIVETo evaluate the conventional cytogenetic methods in genetic diagnosis and prenatal diagnosis in the family with a proband of Angelman syndrome (AS).

METHODSHigh-resolution G-banding karyotyping and fluorescence in situ hybridization (FISH) on metaphase chromosomes were performed.

RESULTSTwo AS patients and 1 normal fetus in the family were successfully detected by FISH.

CONCLUSIONOur result demonstrated that patient with type I AS could be detected by combining the techniques of high-resolution G-banding and FISH with clinical observation, which would offer accurate genetic counseling information to the geneticists and provide the prenatal diagnosis for the AS family.

OBJECTIVETo study DNA damages of liver cells in rats exposed to vinyl chloride monomer (VCM), and the expressions of DNA damage repair enzymes including O(6)-methyl guanine-DNA methyl transferase (MGMT), X-ray repair cross-complementing group 1 (XRCC1) and X-ray repair cross-complementing group 3 (XRCC3); and to explore the repair mechanism of DNA damage induced by VCM.

METHODSRats were exposed to VCM by intraperitoneal injection. DNA damages were detected by single cell gel electrophoresis (comet assay). The expressions of DNA damage repair enzymes were measured by immunohistochemical methods.

RESULTSThe percentages of comet cells in low, moderate, and high dose groups (11.75%, 12.38%, and 17.63%, respectively) were greater than that of control (5.67%). The latter two groups were significantly different from that of control (P < 0.05, P < 0.01). The expressions of MGMT and XRCC1 decreased, and XRCC3 increased with the dose of VCM increased. DNA damage was correlated with the expression of XRCC3 (r = 0.438, P = 0.067).

CONCLUSIONVCM can cause DNA damage of liver cells with dose-response relationship. DNA damage repair enzymes take part in the repairing of DNA damage induced by VCM.

OBJECTIVETo explore a new method for mentoplasty.

METHODSThe bilateral prominent mandibular angle or outer lamina was resected through the intraoral approach. The resected bone fragments were shaped and rigid fixed to the chin with miniplates and screws.

RESULTSA total of 30 patients (28 females, 2 males) accepted chin augmentation with this method. The mandibular angle bone was used in 20 cases and the mandibular outer lamina was used in 10 cases. The operative results were satisfactory, and the patient's facial contour was improved substantially.

CONCLUSIONNo rejection reaction was found after this procedure. Chin augmentation with autogenous mandibular bone is an ideal method for genioplasty.

OBJECTIVETo investigate the treatment of square face with compositive methods. METHODS A total of 71 patients with square-shape face were treated. According to the different face skeleton and desire of patient, mandible angle curved-osteotomy and mentoplasty were used as main methods and zygomatoplasty, buccal fat pad resecting and other aesthetic methods as assistant methods to recontour the whole face skeleton.

RESULTSThe face skeleton of all patients was improved with satisfaction. The following-up period was 6 months to 2 years. In this patients group, massive haemorrhage was occurred during operation in one patient, mental nerve of of one side was injured in two patients, the lip mucosa was wounded in five patients.

CONCLUSIONMandible angle curve-osteotomy and mentoplasty combined with other assistant aesthetic operations were ideal methods to recontour square face. The result was satisfactory.

OBJECTIVESTo explore the relationships between the peripheral blood levels of CD61, CD63, PAC-1 and the incidence of acute rejection and tubular necrosis after renal transplantation, and recovery of the graft function.

METHODSThe peripheral blood levels of CD61, CD63, and PAC-1 of 86 patients with uremia in different stages before and after transplantations were analyzed by flow cytometry. The patients were divided into three groups: (1) twenty-nine patients with normal grafts function, (2) hirty with acute rejection and (3) twenty-seven with acute tubular necrosis. The patients with acute rejection were randomly divided into treatment group with anticoagulants and cntrol group.

RESULTSThe peripheral blood levels of CD61, CD63 and PAC-1 significantly increased (P < 0.05) in the patients with acute rejection, in comparison with those with normal grafts function and those with acute tubular necrosis. The peripheral blood levels of CD61, CD63 and PAC-1 in patients with acute rejection in anticoagulants therapy was lower, recovery time of the grafts function was shorter, one-year survival rates of patients and grafts were higher, as compared with those of controls.

CONCLUSIONSThe patients with acute rejection have significantly high peripheral blood levels of CD61, CD63 and PAC-1 before transplantation, however, these values in patients with acute tubular necrosis are not high, this suggesting that acute rejection might relate to platelet activation, while acute tubular necrosis might not relate to it. After anticoagulants therapy in patients with acute rejection, the grafts function might recover faster and their one-year survival rates and grafts might be higher in those with CD61, CD63 and PAC-1 decreasing remarkably.

OBJECTIVETo assess the reliability and validity of a new Chinese version of the Addiction Severity Index (ASI-C) in drug users in the community.

METHODSThree hundred and eighty-one drug users in the community in Chengdu, Sichuan province were recruited. They were interviewed with a questionnaire consisting of the ASI-C revised on the basis of the previous Chinese version and 38 were interviewed for the second time at an interval of 7 days to evaluate test-retest reliability.

RESULTSCronbach's α coefficients for the internal consistency of the scale varied from 0.49 to 0.86. Test-retest correlation coefficients ranged from 0.50 to 0.93. Criterion validity was found acceptable, as compared with the Symptom Checklist 90 (SCL-90).

CONCLUSIONThe ASI-C presented acceptable reliability and validity in a sample of drug users in the community.
