To investigate the mechanism of Xiefei Dingchuan injection (XFDCI,泻肺定喘注射液) in treating pulmonary hypertension by means of measuring the activity of Ca2＋Mg2＋ ATPase and Na＋K＋ATPase of red blood cell(RBC) membrane.Methods:The pulmonary hypertension models induced by monocrotaline in 18 rats were established then treated with XFDCI.Using cardiac catheter and chromatometry respectively the pulmonary artery pressure (PAP) and the activities of Ca2＋Mg2＋ATPase and Na＋K＋ATPase of RBC membrane were measured.Results:The activities of Ca2＋Mg2＋ATPase and Na＋K＋ATPase of RBC membrane in XFDCI group were obviously higher than those in pulmonary hypertension group.Conclusions:XFDCI is able to reduce the pulmonary hypertension and its mechanisms may be related to increasing the activities of Ca2＋Mg2＋ATPase and Na＋K＋ATPase of RBC membrane.

Some hormones and glucocorticoid in chronic strss feedback are demonstrated to have significant effects on cancer progression.Recently,as a typical neuropeptide,gastrin releasing peptide (GRP) could mediate chronic stress to promote carcinogenesis through four conceivable mechanisms,such as regulating circadian rhythms,suppressing immunity system,acting as a mitogenic effect and mediating cancer-related psychiatric disorders,et al.

Objective To analyze the epidemiological characteristics for new detecting cases of leprosy in 2012, in Yunnan Province, and provide clue and foundation for prevention and treatment in leprosy control. Methods The date of diagnosed leprosy patients in 2012 in Yunnan Province were collected and analyzed by disease reporting information system. Results 230 new cases were founded in 2012, and the discovery rate was 0.50/100 000. 4.35% of new cases were children, 64.35% of new cases were MB and 19.57% had grade 2 disability. 17 recurrent cases were founded in 2012,and 6 of them had received MDT. By the end of 2012, there were still 1084 present case in Yunnan Province,the prevalence rate was 0.24/10 000,and 485 of them need MDT. Conclusion The prevalence of leprosy was decreased,and the prevalence varies a lot in different regions. Honghe and Wenshan are still the focus regions. Leprosy is still a serious public health and social problem in Yunnan Province. In order to reduce the burden of leprosy and eliminate the leprosy danger, long-term financing investment and prevention are still needed.

Objective To explore the clinical effect and safety of methimazole combined with 131I in treatment of hyperthyroidism.Methods Patients (83 cases) with hyperthyroidism accepted in Xi'an Jiaotong University Affiliated San Er Ling Yi Hospital from June 2012 to June 2015 were selected and divided into observation group with 42 cases and control group with 41 cases.Patients in observation group were given methimazole combined with 131I,and patients in control group were given PTU combined with 131I.Then the clinical effect,thyroid gland serological indexes,adverse reations,and reoccurrence rates of two groups were observed and compared.Results The total clinical efficacy of observation group was 95.24％,which was obviously higher than 70.73％ of control group with statistically significance (P ＜ 0.05).TSH was getting higher after treatment of two groups,and T3,T4,FT3,FT4,TRAb,and TPOAb were getting lower after treatment of two groups.And TSH in the observation group was significantly higher than that in the control group,T3,T4,FT3,and FT4 were significantly lower than those in the control group (P ＜ 0.05).The adverse reaction rate of observation group (14.29％) was obviously lower than that of control group (46.34％) with statistically significance (P ＜ 0.05).The reoccurrence rate of observation group (4.76％) was obviously lower than that of control group (26.83％) with statistically significance(P ＜ 0.05).Conclusion Methimazole combined with 131I has good effect and safety in treatment of hyperthyroidism,which is worth of clinical application.

Objective To study the effects of using the dropping retention-enema in the clinical practices.Methods Divided 60 cases who need retention-enema into the experimental group and the control group,there were 30 cases in the each group.The traditional retention-enema method was used in the control group,while the dropping retention-enema method was used in the experimental group.Compared the related factors between the two groups.Results All the factors which can indicated the clinical effects in the experimental group were better than those of in the control group,P

Objective To study the clinical characters,diagnosis and principles of treatmentof acute pancreatitis during pregnancy.Methods Forty-eight cases of acute pancreatitis during pregnancy treated in the recent 8 years were retrospectively analyzed,38 cases had non-surgical treatment(of which 36 cases were cured);10 cases had surgical treatment to remove necrotic tissue and mainly termination of pregnancy.Results Most of the cases in this group had simple pancreatitis,which accounted for 64.58%(31/48).There were 5 cases of maternal(10.42%) death and three cases of fetal(6.25%) death,and all were in patients with severe pancreatitis.Fatality rate of pregnant women with severe pancreatitis was 29.41%.Conclusions Acute pancreatitis during pregnancy is a serious disease with low prevalence rate,but has high fatality rate,and is the primary cause of death in acute abdomen of pregnancy.Nonoperative treatment is the first choice of treatment in this condition.In severe cases,timely surgical intervention is warranted,and the surgical indications should not be altered because of the pregnancy.The safety of both the pregnant woman and the fetus must simultaneously be kept into mind during therapy.

Objective To discuss the clinical manifestations and imaging diagnostic value of tuberous sclerosis accompanied by multi-organ injuries.Methods 2 cases in our hospital and 27 cases of tuberous sclerosis from the published reports were collected.The clinical manifestations and imaging features as well as the extent and type of multi-organ lesion were analyzed.Results Among the 29 patients,17 were male and 12 were female.The averaged age was 16.8.The clinical manifestations included:with family history in 6 , epilepsies in 25 (15 with mental retardation),symmetric angiofibroma in the face in 22 (3 with similar changes in the else body surface),fibromas beneath toenail or fingernail in 4, hyperdactylia of thumb in 2 and abdominal masses in 7 (4 with hematuria), tuberous scleroses beneath ependymal layer in 27,17 patients with kidney diseases,9 involved liver,5 involved spleen.Conclusion Multiple organs can be involved by tuberous sclerosis.The calcification of ependymal lyer and harmatoma of kidney are the most valuable in imaging diagnosis of the disease.

Objective To investigate epidemic status and explore the influential factors of pulmonary tuberculosis (PTB) in the servicemen of armed forces and to provide reference basis for control and prevention. Methods According to the questionnaire, the test of PPD (purified protein derivative), X-ray checking and sputum bacteria culture method had been used. A 1∶1 matched case-control study was carried out in the servicemen with 162 cases and 162 controls. Odds ratios (ORs) were calculated for the relevant factors. Results The prevalence rate of activated tuberculosis, the bacteriological positive prevalence rate, the smear positive prevalence rate and PPD positive reaction rate respectively were 176.66/105, 33.12/105, 22.08/105 and 34.31%. The prevalence rate of officers was obviously higher than that of soldiers, and the army resident in the countryside was higher than that in the city. The prevalence rate of high training intensity was higher than that of low training intensity. With the increasing of the age and time duration in army, the prevalence rate of pulmonary tuberculosis and the positive rate of PPD reaction presented a ascending tendency. Single factor conditional logistic regression analysis showed that the occurrence of PTB was closely associated with training intensity, body mass index, the number of scar, housing condition, the contact history of infection source, area of enrollment and character, their ORs value were 5.12, 0.37, 0.42, 0.51, 1.82, 0.57 and 1.63 respectively (P
