There is an extremely shocking tragedy of a real medical case.The cesarean section couldn't be performed on a full-term in-labor woman because the patient's husband refused to sign the operation validation contract,leading to the death of both the will-be mother and the baby.The above case shows a dilemma between protecting patients' rights of life,being cured and operated and protecting the doctors from being prosecuted in medical treatment.

Ghrelin is involved in the process of feeding behavior and regulation of related energy metabolism,it also modulates the secretion of gonadotropins or transmitters concerning sex hormone releasing.It is considered as the factor connecting the HPG axis and energy metabolism.Body's nutrition has a bearing upon the process of reproductive system's onset and maturation.Adequate body weight is necessary for normal puberty onset.Obese children tend to have an earlier menarche.Ghrelin may pass on the information about nutrition to the hypothamalus in puberty onset.

Objective To determine the therapeutic efficacy of curcumine on inflammatory bowel disease(IBD)and its underlying mechanisms.Methods The rat ulcerative colitis model was developed by using 30 g/L dextran sulfate sodium.Twenty-four young rats were divided into 4 groups:normal group,model group,curcumin 100 mg/kg group(curcumin 100 group),and curcumin 300 mg/kg group(curcumin 300 group).Curcumin was given through gastric gavage once a day for 7 days.General condition,disease activity index(DAI)and histopathological score(HPS)were evaluated.The proportions of CD4+ CD25+ Foxp3+ regulatory T cells(Treg)and CD4+ IL-17+ helper T lymphocyte 17(Th17)in CD4+ T cells in rats,and spleen cells were calculated by using flow cytometry.Immunohistochemical method was performed to determine the level of SOCS3 in colon tissues.Results After curcumin administered through gastric gavage for 5 days,compared with the DAI in the model group[(7.50±0.32)scores],HPS in the curcumin 100 group[(4.00±1.10)scores] and the curcumin 300 group [(5.00±0.89)scores] significantly reduced,and the difference was significant(F=12.469,P<0.05).After curcumin administered through gastric gavage for 7 days,compared with the HPS in the model group[(2.69±0.70)scores],histological score in the curcumin 100 group[(1.94±0.68)scores],the curcumin 300 group [(2.00±0.63)scores] and the normal group[(0.50±0.05)scores] significantly reduced,and the difference was significant(F=33.282,P<0.05).Compared with the model group[(0.015 1±0.000 7)D],the expression of SOCS3 in the curcumin 100 group[(0.002 0±0.000 5)D],the curcumin 300 group [(0.002 6±0.006 0)D] and the normal group[(0.002 2±0.001 0)D] was significantly inhibited(F=382.270,P<0.05),but there was no difference among the former 3 groups(F=0.828,P>0.05).Compared with the model group[(6.5±1.5)％],the propotion of CD4+ CD25+ Foxp3+ Treg cells in CD4+ T cells in the curcumin 100 group[(9.9±1.0)％],the curcumin 300 group [(9.3±0.7)％] and the normal group[(9.6±1.1)％]was obviously upregulated(F=16.635,P<0.05),but there was no difference among the former 3 group(F=1.564,P>0.05).Compared with the model group[(3.5±1.4)％],the propotion of CD4+ IL-17+ Th17 cells in CD4+ T cells in the curcumin 100 group[(2.0±0.9)％],the curcumin 300 group [(1.2±0.6)％] and the normal group[(2.0±0.9)％] was downregulated(F=5.155,P<0.05),but there was no difference among the former 3 group(F=2.073,P>0.05).There was no obvious difference between the curcumin 100 group and the curcumin 300 group in these indicators respectively(all P>0.05).Conclusions Curcumin probably attenuates IBD severity,reduces inflammation and regulates the balance of Treg/Th17 through the inhibition of SOCS3 expression.

OBJECTIVE:To observe clinical efficacy and safety of tegafur combined with three dimensional conformal radio-therapy for advanced esophageal carcinoma. METHODS:Totally 88 cases of advanced esophageal carcinoma admitted into Xuchang central hospital during Aug. 2013-Mar. 2016 were selected and divided into control group and observation group according to random number table,with 44 cases in each group. On the basis of anti-inflammatory,relieving asthma and other symptomatic treatment,two groups accepted three dimensional conformal radiotherapy. Control group was given fluorouracil 80 mg/m2,ivgtt,d1+nadeplatin 70 mg/m2,ivgtt,d1-d5. Observation group was given Tegafur capsules 60 mg,bid,continuous use 5 days,rest for 2 days. A treatment course lasted for 3 weeks,and they received 3 courses of treatment. Clinical efficacies of 2 groups were observed as well as serum inflammatory factors(TNF-α,IL-6,IL-8),lab indexes(VEGF,CA125,CA199,CEA),QLQ-C30 scores be-fore and after treatment. The occurrence of ADR was recorded in 2 groups. RESULTS:The total response rate of observation group was 88.64%,which was significantly higher than 68.18%,with statistical significance(P<0.05). Before treatment,there was no statistical significance in serum inflammatory factor levels,lab index levels and QLQ-C30 scores between 2 groups(P>0.05). Af-ter treatment,serum inflammatory factor levels and lab index levels of 2 groups were significantly decreased,while QLQ-C30 scores were decreased significantly;the observation group was significantly better than control group,with statistical significance (P<0.05). There was no statistical significance in the incidence of ADR between 2 groups (P>0.05). CONCLUSIONS:Tegafur combined with three dimensional conformal radiotherapy shows good therapeutic efficacy for advanced esophageal carcinoma,can significantly reduce serum inflammatory factor levels and lab index levels and improve life quality but do not increase the occur-rence of ADR.

OBJECTIVE To study the application value of protein chip technique in detection of Helicobacter pylori(Hp) infection and clinical diagnosis of associated disease. METHODS The antibodies against CagA,Ure and VacA in 300 serum samples were detected by protein chip technique.The biopsy specimens obtained by gastroscopy from 170 patients with digestive system symptom were detected by modified Giemsa staining at the same time.These patients were also accepted with rapid urease test(RUT) and ~(14)C-urease breath test (~(14)C-UBT).Twenty serum samples from Hp infected patients were detected again after treatment. RESULTS The sensitivity of protein chip technique in detection of Hp infection was 92.5%,the specificity was 41.3%,the total consistent rate was 73.5%,the positive predictive value was 72.8%,and the negative one was 76.5%.The disease was serious in CagA~+ Hp.The antibody′s concentration was lower after treatment in patients infected Hp. CONCLUSIONS The method of protein chip for Hp infection detection could be used in judging the type of Hp.It is suitable for guiding of medicine and the monitoring of treatment.

Hepatitis B virus (HBV) infection is a worldwide health problem and vertical transmission is the main source of chronic infection in Asian countries. Breakthrough perinatal HBV transmission occurs in 10%-15% of infants born to pregnatal women with high viral load even with appropriate postexposure immunoprophylaxis. Management of chronic hepati?tis B (CHB) during pregnancy remains a challenge, with unique issues that involve prevention of mother-to-child transmis?sion (MTCT) and safe use of antiviral therapy. Previous studies indicate that antiviral therapy with analogs (Lamivudine, Tel?bivudine or Tenofovir) may prevent vertical transmission during late pregnancy in highly viremic mothers. This article sum?marized relevant studies that antiviral therapy in preventing MTCT of hepatitis B virus.
