Clinical data of 23 locally recurrent rectal cancer patients underwent radical anterior resection and 69 controls matched by age and gender was retrospectively analyzed to find out the risk factors related to local recur-rence after radical anterior resection of rectal carcinoma. Univariate analysis showed that tumor size, number of positive lymph nodes, distance between tumor and the anal verge and T stage were risk factors for locally recurrent rectal cancer after radical anterior resection. The results of logistic regression analysis showed that T stage ( T4 stage) was an independent risk factor correlated with the tumor recurrence after radical anterior resection and loca-tion of tumor( distance of tumor from the anal verge being less than 5 cm) seemed to be an independent risk factor correlated with the tumor recurrence.

Objective To study the characteristics and treatments of occlusive abdominal injuries during pregnancy. Methods The clinical data of 37 cases with occlusive abdominal injuries admitted in hospital from June 1993 to June 2003 were collected for study. Results All 37 cases received operative treatment, of which two cases complicated by enterorrhexis in the early pregnancy and one by retroperitoneal hematoma were managed using laparoscope. Laparotomy was performed in other 34 cases, of which eight received caesaren section because of placental abruption and enlarged uterus that impeded the management for intraabdominal organs. Of all, 33 cases (33/37,89%) were cured and four (4/37, 11%) died. The postoperative incidence of complications was 16% (6/37). The complications included abdominal cavity infection in two cases (5%), pulmonary infection in three (8%) and multiple organ failure in one (3%). Conclusion Besides obstetrics' diseases, we must keep alert about the injury of abdominal organs during the management of trauma. Accurate diagnosis and timely treatment will win time to save the lives of mother and infant.

Objective To evaluate the clinical efficacy of transcatheter arterial chemoembolization (TOCE) and percutaneous absolute ethanol injection (APEI) in moderate or advanced liver cancer.Method During May,1993～Aug,1999, 137 patients with unresectable advanced liver cancer were retrospectively studied. 85 cases only received TOCE, 52 cases were treated by TOCE+APEI by B-US guidance.Results The effect in TOCE+APEI group was significant better than that in only TOCE group,the half year, 1-year,2-year and 3-year survival rates of the TOCE+APEI group were 86 54%,67 31%,43 55% and 21 77%,while those of the TOCE group were 65 89%,47 92%,22 12% and 1 48% respectively. There was significant difference between the two groups in survival rate(P

Objective To explore the effect of hepatectomy or cholangiolithotomy on patients with hepatocholangic stones. Methods The clinical data of surgical treatment of 316 patients with hepatocholangic stones combined with bile duct stricture was retrospectively analyzed. The patients were divided into two groups:172 patients chiefly underwent hepatectomy,and the other 144 patients chiefly underwent cholangiolithotomy. Results The ratio of residual stones and reoperation in the hepatectomy group was significantly lower than those in the cholangiolithotomy group (P

Objective To study the effect of combined 1,25-dihydroxyvitamin D31,25(OH)2D3 and celecoxib on growth, call cycle and apoptosis in breast cancer cell line Hs578T.Methods We compared cell numbers by using MTT method , analyzed cell cycle percentage and apoptosis with flow cytometric.Results Both with 1,25(OH)2D3 and celecoxib could inhibite tumov growth,induc apoptosis in a dose-time-dependent manner. comparing with 1,25(OH)2D3 alone,combination wse of the two drugs had a additive effect but was inferior to cececoxib alone. The combination use of 10-8mol/L1,25(OH)2D3 and celecoxib group is more effective than the combination use of 10-7mol/L1,25(OH)2D3 and celecoxib group. Conclusion 1,25(OH)2D3 and celecoxib could be a new drug for the prevention and treatment of breast cancer.

Aim To investigate the effects of taxol on apoptosis in Hela cell and the mechanism of apoptosis. The apoptotic cells were detected by TUNEL, HE, eletronic micrpscopy and flow cytometry method. The expressions and activity of apoptosis associated proteins such as PCNA and caspase-3 were examined using S-P and enzyme histochemistric method.The results followed as: HeLa cells exposed to Taxol undergo cell death, presenting morphological and biochemical characteristics typical of apoptosis and the apoptotic cells increased with time and concentration. In contrast to untreated Hela cells, which express low PCNA, Ones treated with Taxol expressed high amounts of PCNA. Conclusion Taxol may induced apoptosis in Hela cell. The apoptosis induced by taxol is related to the increase of PCNA protein and activity of caspase-3.

Objective To investigate the prevalence and risk factor of Ofloxacin resistance among the tuberculosis patients in Shanghai.Methods Totally 447 isolates resistant to anyone of first-line drug (Isoniazid,Rifampicin,Streptomycin and Ethambutol) and 151 randomly selected isolates susceptible to all above drugs were collected from district tuberculosis(TB) hospitals in Shanghai during 2009 to 2010.All 598 isolates were subject to Ofloxacin sensitive test.Logistic regression analysis was conducted to determine risk factors of Ofloxacin resistance.DNA sequencing was applied to study the mutation characteristics in gyrA and gyrB among Ofloxacin resistant isolates.Results Seventy-two(16.1%) of the 447 drug-resistant isolates were found resistant to Ofloxacin,and the Ofloxacin resistant rate among multiple drug-resistant (MDR) isolates was 39.6%(44/111).Ofloxacin resistance was also found in 4(2.6%) of the 151 drug sensitive isolates.Logistic regression analysis showed that first-line drug-resistance MDR(resistant to at least rifampin and isoniazid) and poly-drug resistance(resistance to two or more first-line drugs but not MDR) had significant effect on Ofloxacin resistance(OR = 19.5、5.6,95% CI:6.4 - 59.4、1.7 - 18.1,all P＜ 0.05);re-treatment(OR = 2.3,95 % CI:1.2 -4.0,P＜ 0.05),and a higher age(OR = 1.03,95 % CI:1.0 1 - 1.05,P＜ 0.05)were also significantly associated with Ofloxacin resistance.Resistance mutations in the gyrA and gyrB genes were detected in 62 of 76(81.6%) isolates with phenotypic Ofloxacin-resistance. Conclusions The Ofloxacin resistance rate in Shanghai MDR-TB patients is significantly higher than the pan-susceptible TB patients.Risk factors of ofloxacin resistance are MDR,poly-resistant,retreated patients,age.Among them,MDR has the highest strength of association.

Genomic disorders caused by pathogenic copy number variation (pCNV) have proven to underlie a significant proportion of birth defects. With technological advance, improvement of bioinformatics analysis procedure, and accumulation of clinical data, non-invasive prenatal screening of pCNV (NIPS-pCNV) by high-throughput sequencing of maternal plasma cell-free DNA has been put to use in clinical settings. Specialized standards for clinical application of NIPS-pCNV are required. Based on the discussion, 10 pCNV-associated diseases with well-defined conditions and 5 common chromosomal aneuploidy syndromes are recommended as the target of screening in this consensus. Meanwhile, a standardized procedure for NIPS-pCNV is also provided, which may facilitate propagation of this technique in clinical settings.

With the extensive application of highly sensitive genetic techniques in the field of prenatal diagnosis, prenatal chromosomal mosaicisms including true fetal mosaicisms and confined placental mosaicisms are frequently identified in clinical settings, and the diagnostic criteria and principle of genetic counseling and clinical management for such cases may vary significantly among healthcare centers across the country. This not only has brought challenges to laboratory technician, genetic counselor and fetal medicine doctor, but can also cause confusion and anxiety of the pregnant woman and their family members. In this regard, we have formulated a consensus over the prenatal diagnosis and genetic counseling for chromosomal mosaicisms with the aim to promote more accurate and rational evaluation for fetal chromosomal mosaicisms in prenatal clinics.
