The ecological balance of intestinal microbiota plays an important role in digestion,absorp-tion,metabolism,immunity and protection against pathogens.Intestinal microbiota can not only regulate the innate immunity of the body,but also can stimulate the immune response by the bacteria itself and its metabo-lites.The imbalance intestinal microbiota may lead to abnormal immune mechanism,and then participate in the occurrence and development of the tumor,especially colorectal cancer.

Objective In order to improve the teaching effectiveness of anatomy in nursing, this article made an exploration on the experimental teaching reform combined with the characteristics of nursing profession. Methods The nursing students of class 1and 2 of 2013were set as the research object. The class 1 (110) as experimental class, class 2 (110) for the control group. In the experimental class, the reform of teaching method and teaching quality was improved by adjusting the teaching syl-labus and teaching contents. The control class used the traditional experimental teaching method. The experiment class' teaching reform research of the human anatomy carried on the 1 semester. Exam achievement evaluation and the questionnaire survey were adopted to assess the teaching effect. SPSS 13.0 software was used to do statistical analysis and t test was used to compare two groups of students test scores, experiment grades, test scores and total scores. Results Experimental theory examination results [(47.80±7.30) vs. (44.85±8.38)], experiment grades [(15.48±1.76) vs. (14.55±2.19)], ex-periment test scores [(15.52±2.22) vs. (14.35±2.64)], total score [(78.80±8.99) vs. (73.75±10.53)] were better than control group (P<0.05). In questionnaire survey,more than 80% of the students think that the reformed teaching method can help to improve the teaching effect. Conclusion In human anatomy experiment teaching reform, the reformed experiment teaching method can significantly improve students' scores and the teaching effect. It is better than the traditional method, and is worth publicizing.

Objective To study the gene mutations and clinical features of mandibuloacral dysplasia with type A lipodystrophy (MADA) in a Chinese family. Methods The information of 5 family members including 2 siblings suspected atyp-ical progeria was assembled. Genomic DNA was extracted from peripheral blood of 5 family members, the 12 exons of LMNA gene were ampliifed by PCR and then the PCR products were directly sequenced and analyzed by using Blast software online. The SIFT and PolyPhen-2 software were used to predict the harmfulness of mutations. Results The 2 siblings were clinically diagnosed as MADA. Heterozygous c.1579C>T (p.Arg527Cys) and c.1583C>T (p.Thr528Met) mutations were detected in this family. The father carried c.1583C>T (p.Thr528Met) mutation, the mother carried c.1579C>T (p.Arg527Cys) mutation, and their normal daughter were all heterozygous carriers with c.1583C>T (p.Thr528Met) mutation. Compound heterozygous c.1579C>T (p.Arg527Cys) and c.1583C>T (p.Thr528Met) mutations in 2 siblings led to MADA. The MADA showed an autosomal re-cessive inheritance pattern in this family. Conclusions The 2 siblings with MADA in this family were caused by compound heterozygous mutations in LMNA gene.

Objective To understand the use of antiplatelet drugs in patients with coronary heart disease( CHD) ,and to compare the effect of different anti platelet drugs on cardiovascular events in patients with CHD,and to provide clinical evidence for the optimization of anti platelet therapy?Methods One thousand and twenty?three cases patients with CHD who were treated in the First Hospital Affiliated to Chongqing Medical University from April 2010 to June 2014 were chosen?On the basis of conventional treatment,according to the different anti platelet program,the patents were divided into A group(703 cases),B group(211 cases) and C group(109 cases)?Group A was treated with aspirin and clopidogrel,B group was treated with clopidogrel,and C group was given aspirin therapy?Cardiovascular events( MACE) and bleeding events were observed at 1 month,6 months and 1 year after treatment in the 3 groups?Results After treatment for 1 month,6 months and 1 year,the incidence rates of MACE in group A were 9?1%( 64/703) ,16?6%( 117/703) and 28?4%( 200/703) ,in group B were 14?6%(31/211),25?5%(54/211) and 37?9%(80/211),in group C were 16?5%(18/109),29?4%( 32/109) and 34?0%( 37/109)?After treatment for 1 month,6 months and 1 year,the incidence rates of MACE in group A was significantly lower than group B and C(P<0?05);after treatment for 1 month,6 months,the incidence rates of MACE in group B were lower than group C,while higher than group C after 1 year,but the differences were not signifiacnt( P>0?05)?There were no significant differences in total incidence of deaths,the recurrence rate of myocardial infarction and stent restenosis rate among the three groups ( P>0?05 )?After treatment for 1 month,6 months,the incidence of angina in group A was lower significantly than that in group B and C( P<0?05) ,but When the treatment time was extended to 1 year,there was no significant difference in the three groups(P>0?05)?At 1 year follow?up,the incidence of gastrointestinal bleeding in group A was slightly higher than that in group B and group C ( 4?3% vs? 2?4% vs?3?7%) , but the difference was not statistically significant ( P>0?05 )?Conclusion In the CHD patients receiving aspirin and clopidogrel dual antiplatelet therapy,the incidence of MACE was lower than that in patients with aspirin or clopidogrel treatment alone, especially a reduction in the incidence of angina,and without increase of the risks in the gastrointestinal bleeding events,but the advantages above waning with treatment time extended to 1 year.

Objective To investigate the acute phase adverse effects and influencing factors of adverse effects of diphosphonate treatment in the elderly patients with primary osteoporosis.Methods A total of 208 patients [male 25 patients,female 183 patients,age 60 ～ 93 with a average of (75.51 ± 7.73) years] with primary osteoporosis were selected from 1 Jan 2012 to 30 Nov 2015,admitted to Department of Geriatrics.According to the serious condition of osteoporosis and willingness of patients,208 patients were divided into zoledronic acid treatment group,alendronate treatment group,and pamidronic acid group,and received corresponding diphosphonate treatment.All kinds of adverse reactions of diphosphonate in each treatment group were closely to be observed after administration of diphosphonate in 3 days and 7 days.Results The incidence rate of adverse reactions in the zoledronic acid treatment group (59/134,44.03％;60/134,44.78％) was obviously higher than that in the alendronate treatment group (1/57,1.75％;1/57,1.75％),and the pamidronic acid group (3/17,17.65％;3/17,17.65％) after treatment of diphosphonate in three and seven days (P ＜ 0.05).In different generations,the incidence rate of adverse reactions in the zoledronic acid group and the pamidronic acid group after treatment of diphosphonate in three and seven days was not statistically significant (P ＞ 0.05).There were three patients suffering from severe acute kidney injure (AKI) and three patients suffering from hypokalemia in the 134 patients treatment with zoledronic acid.Conclusions There are obvious differences in the incidence rate of acute phase adverse reactions in the osteoporosis patients who received different treatment policy (P ＜ 0.05).The safety issues in the kidney function and electrolyte abnormality (such as hypokalemia) should be paid much enough attention in the primary osteoporosis patients who receive zoledronic acid treatment.

Objective To discuss the characteristics of renal cell carcinoma with regional lymph node metastasis at diagnosis. Methods The data of 19 patients diagnosed with renal cell carcinoma with regional lymph node metastases at diagnosis from January 2004 to December 2008 were reviewed.The median age was 57 years (29-77).The study group included 15 males and four females.The primary tumor was located in the left kidney in 12 patients and fight in seven patients.The median maximam diameter of retroperitoneal lymph nodes was 2.8 cm(1.5-5.0).The lymph nodes in four patients were not detected by the preoperative image examination,but were confirmed by intraoperative exploration.Eleven cases had enlarged retroperitoneal lymph nodes resected and eight had regional lymph nodes dissected. Results The patients with regional lymph node metastases at diagnosis of renal celI carcinoma accounted for 1.6% (19/1213) of the total renal cell carcinoma cases.With a median follow-up of 34 months,six patients were survival without progression,and seven were survival with progression.giving a 5-year survival rate of 68.4%.The survival and recurrence rates after surgery were not significantly different by Fisher test(P=0.644 and 0.319 respectively) between the patients who underwent retroperitoneal regional lymph node dissection and those who underwent enlarged lymph node resection. Condmiom Renal cell carcinoma with regional lymph node metastasis at diagnosis is uncommon.Some patients may achieve long-term tumor-free survival through regional lymph node dissection or enlarged Iymph nodes resection.

OBJECTIVETo observe the short-term and long-term efficacies on primary dysmenorrhea treated with staging acupoint embedment therapy.

METHODSSeventy cases of primary dysmenorrhea were randomized into an embedment therapy group and a fenbid group, 35 cases in each one. In the embedment therapy group, the embedment therapy was applied twice during the menstrual cycle, one treatment 3 days before menstruation and one treatment during the 12th-14th days of menstruation, respectively. Guanyuan (CV 4), Zigong (EX-CA 1), Diji (SP 8) and Ciliao (BL 32) were the main acupoints in the treatment 3 days before menstruation. Shenshu (BL 23), Ganshu (BL 18) and Pishu (BL 20) were the main acupoints in the treatment during menstruation. In the fenbid group, fenbid was prescribed for oral administration, 0.3 g each time, twice a day, starting 3 days before menstruation till pain was relieved. The treatment of one menstrual cycle was one session. The continuous treatment of 3 menstrual cycles was required. The short-term and long-term efficacies were evaluated at the end of the 3rd cycle and in 3 months after the treatment terminal. The dysmenorrhea score was used to evaluate the efficacy. Visual analogue scale (VAS) and SF-36 were for the assessment of pain degree and life quality.

RESULTS(1) The total effective rate was 91.4% (32/35) in the embedment therapy group after the 3 menstrual cycles, which was better than 74.3% (26/35) in the fenbid group (P < 0.01). In the follow-up stage, the total effective rate was 91.4% (32/35) in the embedment therapy group, which was better than 40.0% (14/35) in the fenbid group (P < 0.01). (2) The differences were not significant in dysmenorrhea score and VAS score after the 1st and 2nd menstrual cycle treatments between the two groups (all P > 0.05). In the 3rd menstrual cycle and the follow-up stage, the dysmenorrhea score and VAS score were reduced obviously in the embedment therapy group as compared with those in the fenbid group (P < 0.05, P < 0.01). The rebound effect occurred in the follow-up stage in the fenbid group. (3) In the 3rd menstrual cycle and the follow-up stage, the improvement in the total score of life quality of the embedment therapy group was superior apparently to the fenbid group (P < 0.05, P < 0. 01).

CONCLUSIONThe staging acupoint embedment therapy achieves the superior short-term and long-term efficacies as compared with the oral administration of fenbid in the treatment of primary dysmenorrhea. As the symptoms of dysmenorrhea and pain are relieved, the life quality is improved.

Objective:To explore the efficacy and safety of 192Ir three-dimensional brachytherapy combined with intensity-modulated radiotherapy in patients with unresectable advanced obstructive extrahepatic cholangiocarcinoma. Methods:A retrospective analysis of the efficacy and safety of 18 patients with unresectable advanced malignant obstructive extrahepatic cholangiocarcinoma admitted to the Cangzhou Hospital of Integrated Traditional Chinese and Western Medicine in Hebei province from January 2014 to January 2018.All patients were pathologically confirmed and received biliary stent implantation, followed by sequential intensity-modulated radiotherapy and 192Ir three-dimensional brachytherapy.The clinical data of all patients were collected, including gender, age, clinical stage, adverse reactions, brachytherapy dose-volume parameters, changes in bilirubin levels before and after treatment, evaluation of efficacy, local control rate and survival rate. Results:All patients successfully completed the treatment.Re-examination was conducted one month after the combined treatment, of the 18 patients, 16 had partial remission (PR) and 2 were stable(SD). Among them, 14 patients had tumor shrinkage after brachytherapy compared with intensity-modulated radiotherapy, and 4 patients showed no significant change.The 6-month local control rate (LC) was 94.4% (17/18). The 1-year survival rate was 55.6% (10/18), and the 2-year survival rate was 38.9% (7/18). Statistical analysis showed that after combined treatment, total bilirubin and direct bilirubin were significantly reduced, and jaundice symptoms were significantly relieved.The adverse reactions of the patient were nausea, vomiting, fever, biliary tract infection, etc.There were no adverse reactions of grade 3 or above.Conclusions:192Ir three-dimensional brachytherapy combined with intensity-modulated radiotherapy in patients with inoperable advanced extrahepatic cholangiocarcinoma has a good local control rate and tolerable adverse reactions, but the impact on long-term survival requires a large sample of controlled studies.

This study was aimed to establish a quality evaluation method, quantitative analysis of multi-components with a single-marker (QAMS) to determine the contents of five saponins in Yao-Bi-Tong (YBT) capsules. Ginseno-side Rg1 was used as the internal standard; the relative correction factor (RCF) of notoginsenoside R1, ginsenoside Re, ginsenoside Rb1 and ginsenoside Rd were calculated and evaluated. The contents of 5 saponins were determined by the external standard method and QAMS, respectively. Rationality, feasibility and repeatability of the QAMS method were verified by comparing the results obtained from two different methods. The results showed that RCFs of notoginsenoside R1, ginsenoside Re and ginsenoside Rb1 to ginsenoside Rg1 against YBT capsules were 0.999, 1.228, 0.990 and 1.094, respectively, indicating good reproducibility. These results of two methods had no significant dif-ference. It was concluded that the QAMS method can be accurately, rapidly and reasonably used as a new quality assessment model for ginsenosides in YBT capsules.
