Objective To investigate the value of laparoscopy in the diagnosis and treatment of unexplained chronic abdominal pain.Methods From January 2014 to February 2016, clinical data of 56 unexplained chronic abdominal pain undergoing laparoscopic surgery were analyzed retrospectively.Laparoscopic exploration was performed firstly and then the corresponding abnormalities were diagnosed and dealt with accordingly.Results The disease causes were explicit in 48 cases (85.7%), including 25 cases of abdominal adhesions, 8 cases of chronic appendicitis, 2 cases of small intestinal diverticulum, 2 cases of intestinal tuberculosis, 2 cases of lymphoma, 5 cases of endometriosis, 2 cases of tubal adhesions, 1 case of peritoneal metastasis of gastric cancer after surgery, and 1 case of appendiceal mucinous adenocarcinoma.Surgical treatment was performed in 43 cases, 3 of whom were converted to laparotomy.There were no postoperative complications in the 56 cases.The follow-up rate was 92.9% (52/56), and lost of follow-up was in 4 cases.The follow-up duration was from 3 months to 3 years (median, 19.4 months).There was 1 death case (peritoneal carcinomatosis).There were 35 cases (62.5%) of complete relief of abdominal pain (no recurrence of preoperative abdominal pain symptoms) and 12 cases (21.4%) of pain relief (preoperative pain decreased or interval extended).The total effective rate was 83.9% (47/56).Conclusion Laparoscopy is of high value in the diagnosis and treatment of unexplained chronic abdominal pain.

Objective To investigate the clinical characteristics of children with dyspepsia diarrhea and the effect of Clostridium butyricum powder combined with changweikang granules on the treatment of the children with this diseases.MethodsFrom February 2013 to October 2015 in department of pediatrics, Tonglu County the First People's hospital, 76 cases with dyspepsia diarrhea as the research object, were randomly divided into the experimental group and the control group, 38 cases in each group.The two groups were given changweikang granules, at this basis, the observation group were given clostridium butyricum powder.3 days for a course of treatment, the two groups were treated for 2coureses continuously.ResultsBefore treatment, there were no significant differences in clinical symptom scores between the two groups.After treatment, the scores of loss of appetite, abdominal pain, diarrhea, abdominal distension and stool in the experimental group were lower than those in the control group, the difference was statistically significant (P<0.05);Before treatment, the serum motilin, gastrin and somatostatin levels in the two groups were not statistically significant.After treatment, the serum motilin and gastrin levels in the experimental group were lower than those in the control group, and the level of serum somatostatin was higher than that of the control group, the difference was statistically significant;After treatment, the total effective rate in the experimental group was 92.11% higher than that in the control group (73.68%), and the difference was statistically significant (P<0.05).ConclusionPediatric indigestion diarrhea often showed loss of appetite, abdominal pain, diarrhea, abdominal distension and stool.The effect is good which clostridium butyricum powder combined with changweikang granules on the treatment of infantile indigestion diarrhea, it is worthy of clinical application.

OBJECTIVE:To explore the clinical efficacy of drug intervention on hypogonadotropic amenorrhea-induced infertili-ty. METHODS:33 patients with hypogonadotropic amenorrhea-induced infertility were included in study,and then received artifi-cial menstrual cycle+HMG+HCG. Therapeutic efficacy was observed. RESULTS:33 patients were included in the study,involving a total of 35 ovulation induction cycles. After treatment,there were 19 cases of pregnancy,5 cases of follicular development(more than 3 mature follicle,giving up HCG treatment and pregnancy plan),6 cases of follicular development(pregnancy failure)and 3 case of follicular development failure. CONCLUSIONS:Exogenous gonadotropin obtain relatively good results in the treatment of hypogonadotropic amenorrhea-induced infertility;but we must pay attention to drug dose so as not to affect the quality of folliculus.

Objective:To establish the HPLC fingerprint of Qinghuo Zhimai tablets and determine the contents of geniposide,andrographolide and dehydroandrographolide.Methods:The analysis was performed on a CAPCELL PAK C18 column (250 mm×4.6 mm,5 μm) with acetonitrile and water as the mobile phase with gradient elution at the flow rate of 1.0 ml·min-1.The detection wavelength was 225 nm,and the column temperature was 40℃.Totally 13 batches of Qinghuo Zhimai tablets from different manufacturers were analyzed to establish the fingerprint of Qinghuo Zhimai tablets.Results:There were 14 common peaks calibrated,and the HPLC fingerprint common pattern was established for the HPLC fingerprint of Qinghuo Zhimai tablets.Using the method of reference substance attribution,3 compounds were determined as geniposide,andrographolide and dehydroandrographolide.The similarity of 9 batches in the 13 batches of Qinghuo Zhimai tablets was higher than 0.9.The content determination of geniposide,andrographolide and dehydroandrographolide showed good linearity (r>0.999 8,n=6),the average recovery was 96.90%,97.55% and 97.07% and RSDs were 1.61%,1.45% and 1.47%(n=9),respectively.Conclusion:The method is simple and accurate with good repeatability,which can be used for the identification and evaluation of Qinghuo Zhimai tablets,and provides important scientific basis for the quality control of Qinghuo Zhimai tablets.

Objective To investigate the expression of CD40 protein in bladder urothelium cancer and to explore its correlation with clinical stage, pathological grades, cell apoptosis. Methods Expression of CD4o protein was evaluated by immunohistochemistry in paracancerous tissues (20 cases) and bladder urothelium cancer tissues (78 cases). Apoptosis of bladder urothelium cancer tissues was detected by Hoechst to determine the apoptotic rate (AR). Results The expression rate of CD40 protein was 2/20(10 %) in the cases of paracancerous tissues, 55/78(70.5%) in the cases of bladder urothelium cancer tissues, a statistically significant differences of CD40 staining was observed between paracancerous tissues and bladder urothelium cancer tissues (P ＜0.01). Overexpression of CD40 was strongly inversely related to the tumor grade and clinical stage; the positive group of CD40 protein was (12.60±0.38)%, the negative group of CD40 protein was (6.77±0.53)%, a statistically significant differences of apoptosis were observed between CD40 protein positive group and CD40 protein negative group (P ＜0.01). It showed CD40 protein might induce cell apoptosis. Conclusion Expression of CD40 protein is closely related with clinical stage, pathological grade and cell apoptotic rate and may offer reliable evidence for diagnosis, treatment and prognosis in bladder urothelium cancer.

Objective To establish an HPLC method for the simultaneous content determination of quercetin and kaempferol in Penthorum Chinense Pursh. Methods The HPLC analysis was carried out on Kromasil C18 (250 mm× 4.0 mm, 5.0 μm) with a mixture of methanol-0.1% phosphate (50:50) as the mobile phase. The determination wavelength was set at 360 nm with the flow rate of 1.0 mL/min. The column temperature was set at room temperature. Results The quercetin and kaempferol showed good linearity in the range of 0.105 6–2.112 0 μg and 0.023 6–0.472 μg respectively. The average recovery rates of quercetin and kaempferol were 98.46% (RSD=2.29%) and 98.17%(RSD=1.99%) respectively. Conclusion The method is accurate and sensitive, which can be used for the content determination of quercetin and kaempferol in Penthorum Chinense Pursh.
