OBJECTIVETo analyze the distribution of single nucleotide polymorphisms (SNP) of growth hormone receptor (GHR) gene in Chinese Han ethnic population.

METHODSThe sample of 106 unrelated healthy Chinese Hans was studied by sequencing exons of the GHR gene to detect SNP.

RESULTSThere were 6 SNP spots identified in exon 6 and exon 10. Five of them were found in exon 10, and one in exon 6. There were differences between the allele frequencies of the SNP we found and those in the NCBI database. The highest heterozygosity of the SNP was found at 1630 A > C (I526L), which was 47.6%. The SNP 1483 A > C (P477T), 1735 A > C (P561T) and 1319 G > T (C422F) had polarity change. The SNP 536 A > G in exon 6 from the NCBI database was not detected in this population. The allele distribution of SNP was in good unity with the Hardey-Weinberg equilibrium.

CONCLUSIONIt is suggested that the SNP of GHR are unevenly distributed and different in different ethnic populations.

OBJECTIVETo describe the temporal trends in the mortality rate of gastric cancer during the period of 1988 and 2010, and to predict the gastric cancer mortality between 2016 - 2020.

METHODSThe data of gastric cancer mortality in Linzhou city between 1988 and 2010 was extracted from the cancer registry, including a total of 11 714 cases, covering 22 447 073 person-years. The mortality rate of gastric cancer of each 5-year period was calculated by sub-site and gender. Age-standardized rate (ASR) was calculated using the Chinese standard population in 1982. Intrinsic estimator (IE) model was used to fit the mortality trend by sub-site and gender, and to predict the mortality of gastric cancer in Linzhou city between 2016 and 2020.

RESULTSFrom 1988 to 2010, the gastric cancer mortality in Linzhou city was 52.18/100 000 (11 714/22 447 073) with the ASR at 49.23/100 000; the mortality in male was 67.02/100 000 (7678/11 455 512) with ASR at 68.68/100 000 while the mortality in female was 36.72/100 000 (4036/10 991 561) with ASR at 32.12/100 000. The mortality of cardia carcinoma was 27.87/100 000 (6257/22 447 073) with the ASR at 26.37/100 000; while the mortality of non-cardia carcinoma was 24.31/100 000 (5457/22 447 073) with the ASR at 22.86/100 000. The ASR of gastric cancer during 1988 - 1990 was 63.37/100 000 (1653 cases) and decreased by 28.34%, to 45.41/100 000 (2622 cases) during 2006 - 2010. The IE model showed that the birth cohort effect decreased greatly. The mortality risk of cardia carcinoma in population born after 1950s, decreased significantly; and the mortality risk of non-cardia carcinoma in population born in 20 century continually decreased. The death of gastric cancer among the population over 30 years old was predicted to be 3626 cases, increasing by 40.60% compared with the number between 2006 and 2010 (2579 cases). Among them, the mortality of cardia carcinoma increased by 51.89% (predicted number between 2016 and 2020 was 2456 cases, and 1617 cases between 2006 and 2010), and the mortality of non-cardia carcinoma increased by 21.62% (predicted number between 2016 and 2020 was 1170 cases, and 962 cases between 2006 and 2010).

CONCLUSIONThe mortality rate of gastric cancer in Linzhou city showed a decreasing trend during the period of 1988-2010, being mainly attributed to the cohort effect. However, the mortality will still increase in the future, between 2016 and 2020.

Objective To explore the survival time and its influencing factors of patients in Guizhou Province after they received antiretroviral therapy(ART)for treating human immunodeficiency virus (HIV)infection and acquired immunodeficiency syndrome (AIDS).Methods A retrospective cohort analysis was conducted to analyze survival time of AIDS patients who received ART in Guizhou Province in 2005-2016,life table method was used to calculate the survival probability,Cox proportional hazards regression model was used to analyze the influencing factors of survival time.Results A total of 15921 patients were included in the study,the median age at the beginning of therapy was(42.13±14.40)years old,58.61% of patients were married/housemate.The length of ART follow-up was (median[P 25 -P 75 ]:15.96[6.00 - 33.00])months.9.77% of the follow-up cases died,59.29% of the deaths occurred within 12 months of initiation of treatment;survival rates in the first,fifth,and tenth year were 93.00%,82.00%,and 74.00% respectively.Cox proportional hazards regression model analysis showed that fe-male patients were 0.58 times more likely to die than male patients(95% CI :0.49-0.68);the risk of death in-creased with increase of ages;the higher the baseline CD4+ T lymphocyte count,the lower the risk of death;the risk of death in patients without symptoms or signs before therapy was 0.70 times than those with symptoms or signs(95% CI :0.60-0.81).Conclusion The antiviral therapy of AIDS patients in Guizhou Province is generally well,patients with high risk factors for death should be paid high attention,it is suggested that medical level and service quality should be improved when patients are treated.

OBJECTIVETo evaluate the feasibility and practicality of laparoscopic hepatectomy for hepatic hemangioma.

METHODSCandidate for laparoscopic liver resection were 18 cases of hepatic hemangioma from January 2002 to October 2006. The portal bloods stream was blocked by the laparoscope portal blood blocker. The Electric-cautery and ultracision were used for liver transection. Operative procedures included anatomical left hepatectomy in 2 cases, non-anatomical left hepatectomy 1 case, left lobectomy 5 cases, local liver resection 10 cases. Two cases of hepatic hemangioma associated with gallbladder stone were performed cholecystectomy synchronously, 1 case associated with chronic appendicitis were performed appendectomy synchronously.

RESULTSLaparoscopic left liver resection was successfully performed in all 18 cases. The operative duration was (185.4 +/- 55.7) min. The quantity of blood lost during the operation was (416.2 +/- 128.8) ml. The postoperative recovery was smooth and good. No critical complications occurred. The duration for hospitalization was (6.2 +/- 1.0) d.

CONCLUSIONLaparoscope hepatectomy for hepatic hemangioma is safe and feasible.

Chronic inflammation is thought to be the leading cause of colorectal cancer, and interleukin-10 (IL10) has been identified as a potent immunomodulatory cytokine that regulates inflammatory responses in the gastrointestinal tract. Although several single nucleotide polymorphisms (SNPs) in IL10 have been associated with the risk of colorectal cancer, their prognostic significance has not been determined. Two hundred and eighty-two colorectal cancer patients were genotyped for two candidate cancer-associated SNPs in IL10. The associations of these SNPs with distant metastasis-free survival and overall survival were evaluated by Kaplan-Meier analysis and Cox regression model. The minor homozygote GG genotype of IL10 rs3021094 was significantly associated with a 3.30-fold higher risk of death compared with the TT+TG genotypes (P=0.011). The patients with IL10 rs3021094 GG genotype also had a poorer overall survival in Kaplan-Meier analysis (log-rank P=0.007) and in multivariate Cox regression model (P=0.044) adjusting for age, gender, carcinoembryonic antigen levels, tumor differentiation, stage, lymphovascular invasion, and perineural invasion. In conclusion, our results suggest that IL10 rs3021094 might be a valuable prognostic biomarker for colorectal cancer patients.

To discuss the effects on early warning of measles, using the neural networks.Based on the available data through monthly and weekly reports on measles from January 1986 to August 2006 in Wuhan city. The modal was developed using the neural networks to predict and analyze the prevalence and incidence of measles. When the dynamic time series modal was established with back propagation(BP) networks consisting of two layers, if p was assigned as 9, the convergence speed was acceptable and the correlation coefficient was equal to 0.85. It was more acceptable for monthly forecasting the specific value, but better for weekly forecasting the classification under probabilistic neural networks (PNN). When data was big enough to serve the purpose, it seemed more feasible for early warning using the two-layer BP networks. However, when data was not enough, then PNN could be used for the purpose of prediction. This method seemed feasible to be used in the system for early warning.

OBJECTIVEThe aim of this study was to investigate the association between urinary cadmium and clinicopathological characteristics of breast cancer.

METHODSThe clinicopathological characteristics of 240 patients with breast cancer were obtained and urine specimens were collected from October 2009 to July 2010. The concentration of urinary cadmium was determined by inductively coupled plasma mass spectrometry (ICP-MS). χ(2) test and Wilcoxon rank sum test were used to analyze whether urinary cadmium is associated with clinicopathological characteristics of breast cancer.

RESULTSThe median concentration of urine cadmium of 240 patients was 1.99 µg/g (25th percentile, 1.32 µg/g; 75th percentile, 2.88 µg/g). HER-2 positive rate, regional/distant metastasis rate, and advanced stage rate in patients with the highest tertile of cadmium concentration were significantly higher than those in the patients with second and lowest Cd tertiles (P = 0.042, P = 0.028 and P = 0.017, respectively), and 28.2% vs. 16.5% for HER-2 and 47.2% vs. 32.0% for regional/distant metastasis, respectively. There were still significant associations between urinary cadmium levels and these clinicopathological parameters after being adjusted in age by unconditional logistic regression model, respectively (P < 0.05).

CONCLUSIONSThe results of this study suggest that urinary cadmium levels are associated with the HER-2 status, regional/distant metastasis status and stages of breast cancer, respectively. Cadmium may induce highly aggressive breast cancer in humans.

OBJECTIVETo evaluate the clinical efficacy and toxicity of vinorelbine (N) and epirubicin (E) as the neoadjuvant chemotherapy regimen in the treatment of locally advanced breast cancer (LABC).

METHODSFrom September 2001 to December 2004, 158 patients with LABC were treated with NE chemotherapy before operation. Neoadjuvant chemotherapy containing vinorelbine (N), 25 mg/m(2) (days 1 and 8) and epirubicin (E), 60 mg/m(2) (days 1) was administered every 3 weeks for three cycles before local treatment.

RESULTSResponse in the breast: the clinical objective response was 81.6% [23.4% (37/158) cCR and 58.2% (92/158) PR], 16.5% (26/158) SD and 1.9% (3/158) PD. Pathological complete response was found in 29 cases (18.3%). Eighteen cases (26.5%) who have positive FNA result in the axillary lymphnode before chemotherapy showed negative result in the surgery specimen. The most common toxicities were neutropenia, alopecia and nausea/vomiting. Neutropenia grade 3 - 4 was reported in 111 patients (70.3%) and there was no toxic deaths.

CONCLUSIONSThe combination of vinorelbine and epirubicin is a very active and well-tolerated regimen as neoadjuvant chemotherapy for the LABC.
