OBJECTIVETo explore the therapeutic effect of diagnosis and treatment program of integrative medicine (IM) on level 2 hypertension in the young and middle-aged patients and their ambulatory blood pressure.

METHODSA randomized, placebo parallel and controlled, multi-center clinical trial was performed. Totally 199 young and middle-aged level 2 hypertension patients were randomly assigned to the treatment group (99 cases) and the control group (100 cases). All received combined hypotensive treatment program by taking Nifedipine Sustained Release Tablet and Hydrochlorothiazide as basic drugs. Patients in the treatment group additionally took Western medicine (WM) combined Jiangyabao serial drugs (0.31 g per tablet, 2 tablets each time, twice daily), while those in the control group additionally took WM combined simulative agents of Jiangyabao serial drugs (0.31 g per tablet, 2 tablets each time, twice daily). The treatment course was 8 weeks for all, and 24-week follow-ups performed. 24 h ambulatory blood pressure and casual blood pressure, and their efficacies were compared between the two groups, and safety assessed as well.

RESULTSCompared with before treatment in the same group, daytime and night casual blood pressure, as well as 24 h ambulatory blood pressure were all obviously improved in the two groups (P < 0.01). Average diastolic and systolic blood pressures at night decreased more in the treatment group than in the control group with statistical difference (P < 0.05). There was no statistical difference in total efficacies of daytime casual blood pressure or ambulatory blood pressure (P > 0.05).

CONCLUSIONJiangyabao serial drugs combined WM in treating young and middle-aged level 2 hypertension patients showed obvious effect in improving night blood pressure, especially for night diastolic blood pressure.

Abstract: Objective　To analyze the treatment outcomes of elderly patients with pulmonary tuberculosis in Chongqing, so as to provide reference for the prevention and control strategies of the epidemic of elderly pulmonary tuberculosis. Methods　The data of tuberculosis cases aged ≥65 years in Chongqing from 2015 to 2020 were collected from the National Health Insurance Information Project Disease Prevention and Control Information system. Descriptive statistical methods were used to analyze the data. Results The registration rates of elderly active pulmonary tuberculosis patients and etiological positive patients were 110.95/10-5and 32.25/10-5 in 2015 and 84.06/10-5 and 57.29/10-5 in 2020. The annual decline rate of active tuberculosis registration was 5.40%, and the annual increase rate of pathogenic-positive tuberculosis registration was 12.18%. The registration rates of active tuberculosis patients and etiological positive patients in the whole population were 70.75/10-5 and 17.63/10-5 in 2015 and 50.34/10-5 and 29.14/10-5 in 2020. The annual decline rate of active tuberculosis registration was 6.58%, and the annual increase rate of pathogenic-positive tuberculosis registration was 10.57%. From 2015 to 2020, a total of 25 931 cases of elderly pulmonary tuberculosis were registered, of which 21 374 (82.43%) cases were successfully treated and 4 010 (15.80%) cases had unfavorable outcomes. The proportion of cured and death patients showed an increasing trend year by year (χ2trend=313.853, 100.502, P<0.01). From 2015 to 2020, the average annual successful treatment rate of elderly pulmonary tuberculosis in the whole city was 82.43%, with the lowest rate in southeast Chongqing (74.23%), followed by urban areas (81.99%). The success rate of elderly pulmonary tuberculosis treatment in the whole city, west Chongqing, northeast Chongqing and southeast Chongqing showed a downward trend year by year (χ2trend=230.199, 35.278, 108.076, 112.130, all P<0.01), with annual decline rates of 2.77%, 2.26%, 3.0% and 4.12%, respectively. Among the registered elderly patients, female, 65-<75 years old, Han nationality, newly diagnosed, no complications, and negative for etiology (χ2=15.234, 255.910, 146.842, 179.998, 25.575, 131.170, P<0.01) had higher success treatment rates. Conclusions The prevalence of pulmonary tuberculosis in the elderly population in Chongqing City is declining, but the positive registration rate of etiology is increasing annually, and the success rate of treatment is decreasing. Therefore, it is necessary to strengthen the systematic management, publicity and education of elderly patients (especially those in southeast Chongqing, male, positive patients and severe patients) to effectively control the epidemic of tuberculosis in the elderly.

Totally, 102 general practitioners (GPs) from 40 community health-care service centers in a district of Beijing were investigated for their awareness of diagnosis, treatment and prevention for chronic hepatitis B and evaluating effectiveness of their training with self-designed questionnaire before and after professional training.Before training, higher awareness of knowledge about prevention for hepatitis B had been achieved in GPs, such as "hepatitis C is communicable" (78/102, 76.5% ), "hepatitis B can be prevented by protective antibody" ( 76/102, 74.5% ), whereas only 3.9% ( 4/102 ) of GPs knew indications of antiviral therapy for chronic hepatitis B, 4.9% (5/102) could describe complications of decompensated cirrhosis and 19.6% (20/102) knew methods for screening primary hepatocellular carcinoma.After training, their awareness increased significantly to 93.1% (95/102), 49.0% (50/102)and 86.3% (88/102), respectively (all P ＜0.01 ).Now, GPs' knowledge about diagnosis and treatment for hepatitis B is still insufficient at community health-care centers and professional training can improve their awareness.It is an important assurance for patients with chronic hepatitis B to be better managed in both of specialized hospitals and community health-care centers by enhancing professional training for GPs indiagnosis and treatment for hepatitis B.

Objective To investigate the feasibility and safety of transvaginal endoscopic cholecystectomy.Methods The clinical data of 88 female patients who underwent cholecystectomy at the Qilu Hospital of Shandong University from May to November, 2009 were retrospectively analysed. Among all the patients, 32 received transvaginal endoscopic cholecystectomy ( NOTES group) and the remaining 56 patients received laparoscopic cholecystectomy (LC). Thirty-two patients who received LC at the same period were selected (LC group)acccording to age, body mass index, type and severity of disease to conduct a matched case-control study. The differences in time span of postoperative pain, anodyne dose, enterokinesia recovery time, operation time, out-ofbed activity time, average hospital stay and hospitalization expenses between the two groups were compared using the paired t test. Results Cholecystectomies were successfully carried out for all the patients. The intraoperative blood loss, operation time, degree of pain, anodyne doses, enterokinesia recovery time, out-of-bed activity time,average hospital stay and hospitalization expenses were (5.7 ± 1.5 ) ml, ( 76 ± 27 ) minutes, 2.2 ± 0.6, ( 10 ±6) mg, (25±5) hours, (9±3) hours, (2.1 ±1.2) days and (1.12±0.34) ×104 yuan in NOTES group, and they were ( 13.9 ± 3.1 ) ml, (38 ± 16) minutes, 6.7 ± 1.5, (28 ± 8) mg, (45 ± 8) hours, (26 ± 6) hours,(4.3 ± 2.1 ) days and ( 1.54 ± 0.18 ) × 104 yuan in the LC group. There were significant differences between the two groups (t = 5.098, - 4.712, 2.417, 3.203, 3.089, 4.136, 4.786, 3.917, P ＜ 0.05 ). Conclusion Transvaginal endoscopic cholecystectomy is safe and feasible, and it is superior to tranditional LC.

OBJECTIVETo observe the clinical efficacy of Shugan Yiyang Capsules in the treatment of asthenospermia and its action mechanisms.

METHODSWe randomly assigned 135 asthenospermia patients to groups A (n = 47), B (n = 45), and C (n = 43) to be treated with Shugan Yiyang Capsules, oral levocarnitine, or combination of the two. We observed sperm quality and the level of α-glucosidase in the seminal plasma before and after medication.

RESULTSThe total effectiveness rate was 70.21% in group A (markedly effective in 16 cases and effective in 17), 68.89% in group B (markedly effective in 15 cases and effective in 16), and 83.72% in group C (markedly effective in 16 cases and effective in 20), significantly higher in C than in A and B (P < 0.05). Both sperm quality and the level of α-glucosidase in the seminal plasma were improved in the three groups of patients, most obviously in group C.

CONCLUSIONShugan Yiyang Capsules can be used for the treatment of asthenospermia, and its effect can be enhanced in combination with oral levocarnitine.

BACKGROUND:Currently, literatures about autologous vein transplantation are few, and the research on the effect of different parts of autologous vein transplantation are not found yet. OBJECTIVE:To summarize the experiences of establishing the fistula using autologous vein transplantation so as to investigate the method of improving the success rate of surgery. METHODS:We analyzed retrospectively the data of 40 cases of establishing the fistula using autologous vein transplantation, and then compared the successful rate of autologous vein transplantation fistula, blood flow and operating time, thereby analyzing the influence of diabetes melitus on the successful rate of autologous vein transplantation fistula. RESULTS AND CONCLUSION:The successful rates of autologous vein transplantation fistula at different parts ranging from high to low were as folows: the cephalic vein, great saphenous vein, basilic vein and smal saphenous vein. Blood flow of the upper limb for vein transplantation fistula was obviously higher than that of the lower limb (P < 0.05). The operating time of autologous vein transplantation fistula was longer in the upper limbs than in the lower limbs (P < 0.01). For patients with diabetes melitus, the successful rate of autologous vein transplantation was markedly lower than those with no diabetes melitus (P < 0.01). For the hemodialysis patients with poor upper limb superficial vein, autologous vein transplantation is a better way of establishing the vascular access. Vein transplantation of the upper limbs is better than that of the lower limbs in success rate and operating time. Autologous vein transplantation fistula is not suitable for the patients with diabetes melitus.

Objective To investigate the expression of TGF-β activated kinase1 (TAK1),phosphoryted TAK1 (p-TAK1) and the density of tumor associated macrophages (TAM) in human pancreatic carcinoma tissues and pairing adjacent normal pancreatic tissues,and explore their relationship.Methods The expression of TAK1,p-TAK1,CD68 (the marker of tumor associated macrophages) proteins in 57 samples of pancreatic cancer tissues and 35 samples of pairing adjacent normal pancreatic tissues were detected by immunohistochemical method,then the density of TAM was evaluated.The relationship between the protein expression and TAM,and the relationship between them and clinicopathologic parameters were examined using SPSS 18.0 software,and the independent risk factors of TNM staging were analyzed by multivariate logistic regression.Results TAK1 and p-TAK1 were positively expressed in 42.1％ (24/57) and 40.4％ (23/57) pancreatic carcinoma tissues,significantly higher than adjacent normal pancreatic tissues [14.3 ％ (5/35) and 11.4％ (4/35)];the proportion of pancreatic carcinoma tissues with high density TAM was 38.6％ (22/57),higher than that of adjacent pancreatic tissues [8.6％ (3/35)],the differences were statistically significant (P＜0.05).TAK1 expression was positively related to tumor size,tumor differentiation,lymph node metastasis,distant metastasis and clinical staging;p-TAK1 expression was positively related to tumor differentiation,lymph node metastasis,distant metastasis and clinical staging;the density of TAM was positively related tumor differentiation,lymph node metastasis,distant metastasis and clinical staging (all the P values were less than 0.05).The expression of TAK1 and p-TAK1were positively correlated with the density of TAM (P ＜0.001).Multivariate logistic regression analysis showed that high density of TAM was independently associated with advanced clinical staging (P =0.002,OR =129.5,95％ CI 6.2 ～2718.6).Conclusions TAK1 pathway and TAM may play an important role in the pathogenesis and progression of pancreatic cancer,and there may be synergy effect between them.
