Objective To observe the therapeutic effect of clarithromycin combined with Cassia Twig-Poria Cocos capsule on patients with chronic pelvic inflammatory disease and its influence on high sensitivity C - reactive protein (hs-CRP). Methods 106 cases of patients with chronic pelvic inflammatory disease were selected to be divided into the observation group and control group with each group of 53 patients. The patients in control group were only given clarithromycin, on the base of control group, patients in observation group were given Cassia Twig-Poria Cocos. Both group were treated for three courses of 7-14 days. Then the therapeutic effect, adverse reactions, hs-CRP, erythrocyte sedimentation rate and hematocrit of patients were investigated. Results The total effective rate of patients in observation group was 90.57%, and the control group was 75.47%. The total effective rate of observation group was higher than control group with statistically significant difference (P<0.05). The hs-CRP, erythrocyte sedimentation rate and hematocrit of two groups both decreased after treatment (P<0.05) and these indexes of observation group was much less than control group (P<0.05). Besides, there was no difference of incidence of adverse reactions between two groups during the treatment. Conclusion Treatment of clarithromycin combined with Cassia Twig-Poria Cocos capsule on patients with chronic pelvic inflammatory disease not only can lessen inflammatory reaction, but also can improve the therapeutic effect effectively.

Objective To analyze the clinical value of Guizhi Fuling capsules combined with fosfomycin trometamol power in the treatment of pelvic inflammatory disease and pelvic effusion.Methods A total of 60 patients with pelvic inflammatory disease and pelvic effusion from February 2013 to March 2016 in our hospital were selected and divided into the control group and the observation group , 30 cases in each group.The control group were treated with fosfomycin trometamol power, and the observation group were additionally treated with Guizhi Fuling capsules.The therapeutic effects and changes of TCM syndrome scores were compared between the two groups.The levels of serum C reactive protein ( CRP ) in the two groups were determined before and after treatment and the ultrasound examination was performed and changes of pelvic effusion diameter was determined before and after treatment.Results The total effective rate of the observation group was higher than that of the control group, the difference was statistically significant (P<0.05).There was no significant difference in TCM syndrome scores between the two groups before treatment .After treatment, the TCM symptom scores of both groups were decreased, the difference was statistically significant ( P<0.05 ) .The scores of lumbosacral swelling pain, abdominal pain, morbid leucorrhoea increase, fatigue, low-grade fever and soreness of waist in the observation group were lower than those in the control group, the difference was statistically significant (P<0.05).Before treatment, there was no statistically significant difference in pelvic effusion and CRP levels between the two groups.After treatment, the pelvic effusion diameter and CRP levels were decreased, the difference was statistically significant (P<0.05), and those in the observation group were lower than the control group, the difference was statistically significant (P<0.05). Conclusion Guizhi Fuling capsules combined with the fosfomycin trometamol power is significantly effective in the treatment of pelvic inflammatory disease and pelvic effusion.It can significantly reduce the inflammatory reactions of patients, and improve the TCM syndrome scores.

Background and purpose: The ataxia-telangiectasia mutated (ATM) gene results in ataxia-telangiectasia (A-T) and it is closely associated with tumors. ATM is an important signal transducer that is involved in the repair of DNA double-strand break damage by phosphorylating numerous target proteins . This study was aimed to investigate the correlation between a single nucleotide polymorphism (SNP) in ATM gene (IVS62+60G>A) and the risk of non-small cell lung cancer(NSCLC) in a case-control study. Methods: From June 2004 to December 2005, a total of 264 patients with NSCLC were recruited, 264 healthy people as control. All of specimens were collected from Zhejiang Tumor Hospital. DNA was extracted from peripheral blood and then was used to determine. ATM genotype by Taqman SNP genotyping assays. Logistic regression model was employed to analyze the relationship between SNP and NSCLC risk. Results: The percentage of NSCLC patients in 86 patients with A/A genotype, 139 patients with A/G and 39 patients with G/G were 32.6% (86/264), 52.6% (139/264), 14.8% (39/264), respectively. The percentage in 68 healthy people with A/A genotype, 139 healthy people with NG and 55 healthy people with G/G were 26.0% (68/262), 53.0% (139/262) and 21.0% (55/262), respectively. The proportion of G/G genotype in 264 patients was obviously lower than that in the 264 healthy control (14.8% vs 21.2%, P<0.05). The people with G/G genotype had lower risk to NSCLC than there with A/A genotype (OR=0.561, 95% CI=0.334-0.942, P=0.029). Conclusion: The ATM SNP(IVS62+60G>A)was associated with the NSCLC risk, and homozygous G alleles may be a protective factor to NSCLC.

Objective To evaluate the outcome of radiotherapy for recurrent esophageal cancer after surgery and to determine the prognostic factors. Methods From Jan 2004 to Dec 2009, 93 patients of esophageal carcinoma with loco-regional recurrence as the first site of failure after surgery were retrospectively reviewed. Kaplan-Meier method was used to analyze the survival. Logrank test was used to evaluate the difference between the groups. Multivariate survival analysis was conducted using a Cox proportional hazard regression model with a backward stepwise procedure. Results The overall survival rates at 1, 2 and 3 years were 40. 9% , 10. 1% and 6. 7% ,respectively,but with a median survival time of 11.0 months(95% CI 9. 4-12. 6) . In univariate analysis, age,PS, radiation dose and retreatment methods were independent prognostic factors. In multivariate analysis, only radiation dose and retreatment methods were independent prognostic factors for overall survival. Conclusions The prognosis of patients with postoperative loco-regional recurrence of esophageal cancer is poor. However, a long-term survival maybe expected by definitive chemoradiotherapy.

Objective To observe the effect of a rotating magnetic field in preventing and treating irradiation-induced esophagitis in rats. Methods Forty female Wistar rats were randomized into 5 groups:a non-irradiated control group,an irradiation group,an amifostine treatment group ( amifostine group ),a 90 min magnetic field treatment group (90 min magnetic group) and a 120 min magnetic field treatment group ( 120 min magnetic group),with 8 rats in each group.The esophaguses of all rats except those in the control group were exposed to a single irradiation with 6 MV X-rays from a linear accelerator at a dosage of 43 Gy.Four rats in each group were randomly chosen to be observed 1 and 2 weeks after the irradiation.Blood cytokines were detected in their arterial blood.Any pathological changes of the esophagus were observed with HE staining under a light microscope at the same time. Results Irradiation-induced esophagitis was observed in the irradiation group 7 days after irradiation,with obvious exfoliation and necrosis of the esophagal epithelium mucosae.The submucosa were hyperaemic and dropsical with abundant inflammatory cell infiltration.The pathological changes of the esophagus were similar at 7 and 14 days after irradiation.However,the irradiation-induced esophagitis of rats in the amifostine group,the 90 min magnetic group and the 120 min magnetic group were relatively slighter and the blood leucocytes and neutrophis in those 3 groups were significantly lower than those in the irradiation group,while a tendency toward repair of the mucosa of the esophagus was detected.Serum TNF-α,IL-1 and IL-6 in the 90 min magnetic group and 120 min magnetic group were significantly lower than those in the irradiation group. Conclusions Both a rotating magnetic field and amifostine can help prevent and treat irradiation-induced esophagitis.Their therapeutic efficacy is similar.Exposure to a rotating magnetic field could inhibit the expression of inflammatory factors,and thus lessen the inflammatory reaction of acute irradiation-induced esophagitis.

Objective To investigate the clinical features of pedistric Littre hernia.Methods Clinical data of 11 cases of Littre hermia admitted from January 2002 to December 2010 was studied retrospectively.Results The diagnosis of Littre hernia was all established by laparotomy.All of the 11 cases were boys,the median age was 1.2 years (22 days to 3 years and 7 months).The main clinical features were:painful,irregular and nonresetable mass in the groin area (11/11),vomiting in 6 cases (6/11 ),fever (＞38.5 ℃ ) in 4 cases (4/11 );X-ray showed intestinal obstruction in 9 cases (9/11 ),Ultrasound found mixed mass in the groin area in 11 cases ( 11/11 ),pouch-like structure were found in 6 cases (6/11).Eight cases (8/11) presented with elevated WBC ( ＞ 10000).Palpable lobulated structure were fell in 5 cases (5/11).All cases of Littre hernia were successfully operated on,Meckel diverticulum perforation was found in 2 cases ( 2/11 ),Meckel diverticulum adhered to the hernia sac in 8 eases (8/11).All patients were cured by surgery,and postoperative follow-up (10ms-8y) found no recurrence.Conclusions Pediatric Littre hernia is rare,preoperative diagnosis is difficult.Avoiding preoperative violent reduction and intraoperative injuring Meekel's diverticulum or the small bowel helps improve the cure rate of Littre hernia in children.

A total of 105 patients with first-episode schizophrenia (male =51,female =54) and 99 normal controls (male =51,female =48) were included into this retrospective case-control study.Childhood trauma questionnaire-28 item short form (CTQ-SF) was used to assess the experience of childhood abuse.The result of binary logistic regression showed that emotional abuse (β =0.630,P ＜ 0.05) and emotional neglect(β =0.270,P ＜ 0.05) were included into the final model of predicting schizophrenia.It indicates that patients with first-episode schizophrenia experienced more early life stress than controls.Particularly emotional abuse and emotional neglect may play important roles in the onset of schizophrenia.
