Method Eighty patients with chronic simple rhinitis due to yang deficiency were randomized into a treatment group and a control group, 40 in each group. The treatment group was intervened by acupuncture plus heat-sensitive moxibustion, while the control group was by medication. The symptom and sign score was observed before and after 1-week treatment, and the clinical efficacy was compared. Result The total effective rate was 85.0%in the treatment group versus 55.0% in the control group, and the difference was statistically significant (P<0.05). The symptom and sign scores were changed significantly after treatment in both groups (P<0.01,P<0.05). After treatment, the symptom and sign score in the treatment group was significantly different from that in the control group (P<0.05). Conclusion XIE’s Wen Du Qu Mai needling method is effective in treating chronic simple rhinitis due to yang deficiency.

Objective This study aims to observe and analyze the result of implementing health management and intervention for chronic Keshan disease treatment. Methods Certain amounts of chronic Keshan disease patients in Keshan disease area were chosen and given health management and treatment intervention including primarily pharmacological treatment for the chronic congestive heart failure together with health education and life style instruction. From 2006 to 2008, three interventions were conducted every six month. Electrocardiogram description, proportion of heart to chest, classification of heart function, types of Keshan disease and labour capacity at the initial and the last stage of the intervention were taken as judging indexes. If one of the indexes was improved then the intervention will be regarded as effective. The number of effective cases and effective rate were counted in order to observe the impact of intervention times and different medicine on intervention results. Results Altogether 345 Keshan disease patients were involved in the study, among them 207 were effective, the effective rate was 60%(207/345). One hundred and eighty were involved in the intervention for once, and the effective rate was 44%(79/180). Ninty-one took part in the intervention twice, and the effective rate was 66%(60/91). Seventyfour attended the intervention for three times, and the effective rate was 92% (68/74). There were significant difference among groups of different intervention times (χ2 = 52.16, P < 0.01), and the effective rate increased with increased intervention times. Three times were higher than that of one or two times (χ2= 15.81, 49.56, all P< 0.0125). Twice were better than once(χ2 = 11.76, P < 0.0125). There were significant difference among groups of different medicine groups(χ2 = 19.56, P< 0.01). Among different medicine groups, the efficacy of angiotensin converting enzyme inhibitor(ACEI) group was the highest 77%(82/106) while the cardiotonic medicine group was 50%(47/94) and cardiac muscle nutrition poisons was 54% (78/145). The efficacy rate of ACEI group was higher than that of cardiotonic medicine group and cardiac muscle nutrition poisons(χ2 = 16.28, 14.71, P< 0.0125). Conclusions The implement of health management and treatment intervention to Keshan disease patients is of great significant in improving the healthy condition of Keshan disease patients. Health education and life-style instruction as well as the use of ACEI, β-blockers and diuretic have comparatively obvious effect on treatment of chronic Keshan disease congestive cardiac failure.

AIM:To explore the clinical effect of capsule membrane phacoemulsification and capsular bag in phacoemulsification in treatment of hard nuclear cataract with high myopia.
METHODS:A total of 297 patients(322 eyes) with hard nucleus cataract(Ⅳ-Ⅴ grade nucleus) and high myopia were selected from Mar. 2014 to Mar. 2016 in our hospital. They were randomly divided into the observation group with 149 cases(162 eyes) and the control group with 148 cases(160 eyes). The observation group received capsule membrane phacoemulsification and the control group received capsular bag in phacoemulsification. The therapeutic effect and safety of patients in two groups were compared. The comparison of phacoemulsification time, energy parameters and corneal endothelial cell density used t-test, post-operative visual acuity and the occurrence of complications were tested by Chi-square test.
RESULTS: The harder the nucleus was, the longer the phacoemulsification time and higher the average phacoemulsification energy was, and the differences were statistically significant(P<0. 05). The phacoemulsification time and energy parameters of the observation group were significantly lower than that of the control group( P<0. 05 ). One month after operation, the postoperative visual acuity in two groups was significantly higher than the visual acuity at 1d after operation(P<0. 05). But there was no statistical significance on the visual acuity at 1mo after operation between two groups ( P> 0. 05 ). After operation, the density of corneal endothelial cell in two groups was significantly lower than the density before operation ( P < 0. 05 ). But there was no statistical significance on the density of corneal endothelial cell after operation between two groups ( P > 0. 05 ). The intraoperative complication rate of observation group was significantly lower than that of the control group ( P<0.05 ) , but there was no statistical significance on postoperative complication rate between two groups ( P>0. 05). CONCLUSION: For the treatment of hard nuclear cataract with high myopia, capsule membrane phacoemulsification and capsular bag in phacoemulsification have similar effect, but capsule membrane phacoemulsification has better safety.

Objective To investigate the current prevalence of depressive disorder and the associated factors in pa?tients with essential hypertensive from cardiovascular divisions of tertiary general hospitals. Methods A Chinese version of Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) Axis I Disor?ders was conducted by five mental health professionals on 876 essential hypertensive outpatients at cardiovascular divi?sions of tertiary general hospital. Data on the socio-demographic and clinical characteristics of these hypertensive pa?tients were also collected. Results The current prevalence of depressive disorders among essential hypertensive outpa?tients of tertiary hospitals was 16.6%(145/876). Risk factors for depressive disorders in hypertensive patients included fe?male gender (OR=2.817, 95%CI:1.161~6.885), being 65-year-old and older (OR=1.747, 95%CI:1.118~2.688), non-marital status (OR=2.023, 95%CI:1.203~3.398), gradeⅢhypertension (OR=1.776, 95%CI:1.226~2.333) and car?diovascular diseases (OR=2.018, 95%CI:1.427~2.587). Conclusion Essential hypertensive outpatients, who receive med?ical services at cardiovascular divisions of tertiary general hospital, have high prevalence of depressive disorders. Clini?cians should pay more attention to the mental health of outpatients with essential hypertension.

Tropane alkaloids,such as hyoscyamine (or its more stable racemate atropine) and scopolamine,are remembered as the oldest drugs in medicine with wide pharmaceutical applications clinically for their mydriatic,antispasmodic,anticholinergic,analgesic and sedative properties.Presently,the supply of tropane alkaloids are entirely rested on their isolation from plant materials,yet the low contents of tropane alkaloids in plants raise the requirement to breed new varieties of high-yield tropane alkaloids and improving the production of tropane alkaloids in hairy root cultures or plants by biotechnology has be a research focus in the field of secondary metabolism.For the past decade,there have been important progresses on biosynthesis of tropane alkaloids and their molecular biology,some new pathway genes have been identified and many achievements have also been acquired in metabolic engineering of tropane alkaloids.This review summarized the recent advances in above aspects,and the problems and orientations of future research are also discussed and proposed.

Single-agent gemcitabine, the standard chemotherapy for pancreatic cancer, has only mod-est effect. Gemcitabine has been combined with a variety of cytotoxic agents and targeted agents. Most phase Ⅲ studies, however, have failed to show improved survival compared with gemcitabine alone. One phase Ⅲ study has shown improved survival in advanced pancreatic cancer by adding erlotinib to gemcitabine. Studies evalua-ting non-gemcitabine-based regimens have showed considerable promise.

[Objective]To investigate the technique and significance of arthroscopic anterior cruciate ligament(ACL) reconstruction with the remaining bundle and ruptured fiber.[Method]In 47 cases of ACL rupture verified with arthroscopy,there were 15 cases of partial disruption,26 cases of complete disruption,and 6 cases of ligament flabby.ACLs were reconstructed with single bundle of autogenous quadrupled hamstring tendons under arthroscopy without remove of the remaining bundle or remnants of ACL.The femur tunnel was fixed by the RigidFix system,and the Intrafix system was used to fix the tibia tunnel.[Result]All of 47 cases were followed up for an average of 19 months(ranged from 12 to 24 months).The stabilization was strengthened after operation.Lysholm knee function score increased by 26.3 scores,from average 68.6 scores of preoperation to average 94.9 scores after operation.Lachman test was negative in 43 cases,weakly positive in 3 cases and positive in 1 case.According to Insall knee therapeutic effect evaluation criterion,38 cases achieved excellent results and 9 cases achieved good results.[Conclusion]Arthroscopic reconstruction of ACL with the remaining bundle preserving technique could facilitate revasculization and reinnervation of the reconstructed ligament and maintain stability of knee joint.
