OBJECTIVETo investigate the impact of adding folic acid, vitamin B(12) and probucol to standard antihypertensive medication on plasma homocysteine (Hcy) and asymmetric dimethylarginine (ADMA), serum NO and eNOS of essential hypertensive patients.

METHODA total of 120 patients with hypertension were randomly divided to three groups (n = 40 each): group 1 (standard medication), group 2 (adding folic acid 5 mg/day and vitamin B(12) 500 µg twice daily) and group 3 (adding folic acid 5 mg/day and vitamin B(12) 500 µg twice daily and probucol 500 mg twice daily). Plasma Hcy and ADMA, serum NO and eNOS levels were observed at baseline, 2 and 12 weeks after various therapy.

RESULTSIn group 1, concentrations of plasma Hcy [(23.06 ± 14.15) µmol/L, (23.67 ± 12.31) µmol/L, (23.25 ± 11.64) µmol/L], ADMA [(0.21 ± 0.12) µmol/L, (0.23 ± 0.13) µmol/L, (0.21 ± 0.09) µmol/L] and serum NO [(64.14 ± 15.07) µmol/L, (65.29 ± 15.04) µmol/L, (65.32 ± 13.58) µmol/L], eNOS [(20.02 ± 4.50) µg/L, (20.79 ± 4.03) µg/L, (19.82 ± 5.70) µg/L] remained unchanged during the 12 weeks therapy (all P > 0.05). In group 2, concentrations of plasma Hcy [(12.54 ± 6.49) µmol/L] and ADMA[(0.18 ± 0.07) µmol/L] were significantly decreased after the treatment of 12 weeks than the treatment baseline value [(21.51 ± 7.82) µmol/L, (0.20 ± 0.12) µmol/L] and 2 weeks value[(19.38 ± 8.14) µmol/L, (0.21 ± 0.12) µmol/L], however the concentrations of serum NO and eNOS showed contrary results of the Hcy and ADMA's. (all P < 0.05). In group 3, similar changes occurred at 2 weeks after therapy (P < 0.05 2 weeks vs. baseline and 12 weeks vs. 2 weeks). Plasma ADMA level was positively correlated with Hcy at baseline (r = 0.546, P < 0.05).

CONCLUSIONSSupplementation of folic acid, VitB(12) and/or probucol helps to improve endothelial function and reduce plasma Hcy and ADMA levels in patients with hypertension.

OBJECTIVETo explore the role of autophagy in doxorubicin (DOX)-induced resistance of human myeloma cell line RPMI8226.

METHODSWe established doxorubicin induced resistant subline of myeloma cell line RPMI8226/DOX by drug concentration step-elevation method. Resistant index of DOX was measured by MTT assay. Autophagy of myeloma cell lines RPMI8226/s and RPMI8226/DOX was detected by transmission electron microscopy, immunofluorescence (LC3-FITC) and western blot respectively. Apoptosis of RPMI8226/DOX cells induced by DOX combined with autophagic inhibitor hydroxychloroquine or 3-MA was identified by AnnexinV-FITC/PI double fluorescence dyeing.

RESULTSResistant index of RPMI8226/DOX was approximately 10.8 fold of that of RPMI8226/S. Electron microscopic studies revealed that most of RPMI8226/DOX cells displayed viable attributes and contained numerous autophagic vacuoles. Fluorescent images of RPMI8226/DOX cells showed a punctuate distribution in LC3 protein. Increased LC3-II protein in RPMI8226/DOX cells was determined by immunoblotting. There were no differences among 8 μmol/L HCQ (3.24±1.08)%, 10 mmol/L 3-MA (2.81±0.80)% or control \[(2.12±1.24)%\] (P>0.05) in terms of AnnexinV-FITC/PI double fluorescence dyeing; Compared with apoptosis of (9.75±2.15)%, (24.36±2.16)% and (40.51±3.14)% of RPMI8226/DOX cells under 2, 4 and 6 μmol/L DOX, apoptosis increased significantly after 24 h incubation under 2, 4 and 6 μmol/L DOX combined with 8 μmol/L HCQ as of \[(16.56±1.89)%, (36.44±2.91)% and (62.68±3.75)%, respectively\], or under 2, 4 and 6 μmol/L DOX combined with 10 mmol/L 3-MA as of \[(15.47±1.85)%, (39.28±3.06)% and (55.46±4.07)%, respectively\] (P<0.05).

CONCLUSIONAutophagy was involved in doxorubicin-induced resistance of myeloma cell line RPMI8226, DOX resistance in myeloma cells was reversed partly by autophagy inhibitor hydroxychloroquine or 3-MA, and autophagy may be one of mechanisms for drug resistance.

OBJECTIVETo observe therapeutic effect of acupuncture method for consciousness-restoring resuscitation on cerebral infarction with hyperlipidemia.

METHODSSixty cases of apoplexy with hyperlipidemia were randomly divided into a consciousness-restoring resuscitation acupuncture group (treatment group) and a Chinese medicine control group (control group), 30 cases in each group. TCM symptomatic scores and indexes of blood lipids were detected before and after treatment in the two groups.

RESULTSThe total effective rate for improvement of blood lipids was 72.4% in the treatment group, which was not different from that (65.5%) in the control group (P> 0.05); the total effective rate for clinical symptoms was 89.7% in the treatment group, which was better than that (62.1%) in the control group (P < 0.05). The treatment group was superior to the control group in improvement of numbness and twinge in extremities, dizziness, distention and oppressed feeling in chest and hypochondrium, anorexia, sleepy and weakness (P < 0.05).

CONCLUSIONAcupuncture method for consciousness-restoring resuscitation can regulate metabolic disorder of lipids and improve main clinical symptoms in the patient of cerebral infarction with hyperlipidemia.

OBJECTIVETo investigate the epidemiology of pediatric human immunodeficiency virus (HIV) infection in six provinces of China.

METHODSA cross-sectional study was conducted in six provinces with the highest HIV prevalence. Surveys on demographics and HIV-related questions (transmission modes, time of diagnosis, clinical stage, laboratory test) were distributed to clinicians in these provinces. Descriptive and bivariate analyses were performed on the completed surveys.

RESULTSSurvey results of 650 children [405 males and 245 females; average age: (7.9 +/- 3.2) years] were eligible for analysis. The interval between possible transmission and diagnosis was (7.1 +/- 3.2) years. The location distribution was as follows: 570 cases (87.7%) in Henan Province, 23 cases (3.5%) in Guangxi Province, 21 cases (3.2%) in Yunnan Province, 19 cases (2.9%) in Hubei Province, 10 cases (1.5%) in Anhui Province, and 7 cases (1.1%) in Shanxi Province. Transmission routes included mother-to-child transmission (75.1%), blood transfusion/ plasma donation (15.7 %), and injecting drug use (IDU, 0.5%). Former plasma donation (FPD) was the main transmission route in some provinces (Henan, Shanxi, Hubei, and Anhui), while IDU was the main transmission route in other provinces (Guangxi and Yunnan). The average age in the FPD provinces was significantly higher than that in IDU provinces [(8.1 +/- 3.2) vs. (5.4 +/- 2.2) years, P <0.001]. Among 178 patients in all six provinces who required treatment (on the basis of CD4 count or WHO staging), 133 (74.7%) did not receive treatment and 45 (25.3%) received antiretroviral therapy.

CONCLUSIONMother-to-child transmission is the main transmission mode in pediatric patients. Efforts should be made to strengthen the diagnosis and treatment of pediatric HIV/AIDS patients.

OBJECTIVE: To summarize the research status and influencing factors of the time-effect of acupuncture and to explain and analyze the optimal effect timing of acupuncture, and provide reference for obtaining the best clinical therapeutic effect. METHODS: Literature regarding the studies of the time-effect of acupuncture published from January 2000 to August 2018 was searched, concluded and analyzed in CNKI, WANFANG, VIP and PubMed databases. RESULTS: A total of 43 papers were included. The time-effect relationship of acupuncture was studied from various aspects: immediate effect, post-effect and total time-effect. The influencing factors of time-effect of acupuncture included needle retention time, acupoint types, number of acupoints and frequency of acupuncture treatment. CONCLUSION Even though preliminary achievements have been made in the study of the time-effect of acupuncture, there are many limitations and deficiency. These studies are mostly isolated and unsystematic, and the observation time of needle retention time and post-effect is not long enough to observe the exact best induction period, half-life period and residual effect period of acupuncture.In the future, we should combine the existing research experience and achievements to formulate a more reasonable research plan and observe the entire period of acupuncture in a longitudinal direction.

[Abstract] Objective The purpose of this study is to construct a high-resolution model focusing on the vascular pattern of the scaphoid by using micro CT and to provide anatomical reference for the daily clinical use. Methods The lead-based contrast was perfused from the brachial artery and then the scaphoid bone was harvested. 3D models of the scaphoid bones were constructed by using micro CT to show how arteries distributed in and on the bones. Results The arteries on the surface stretched from the distal radius covered with scaphoid fossa to the radial side of the waist and then head back to the distal ulna along the dorsoradial ridge, formed like a letter “Ⅴ”. The arteries gathered at the inflection point of the letter “Ⅴ” and the dorsal region. The tubercle region was anastomosed extensively with 3 to 5 major intraosseous vessels originated from the extraosseous vessels covering the waist and the tubercle. There are only 1 to 2 major intraosseous vessels entering the bone via a long route from the ulnar side. The vessels running in the scapholunate ligament didn’t spilt into any intraosseous branches. Conclusion The superficial vascularity formes a “Ⅴ”-like pattern. The inflection point of the letter “Ⅴ” and the dorsal region display a dense vascularization and these vessels contributed a lot to the intraosseous vascularity.

OBJECTIVE: To evaluate the reporting quality of randomized controlled trials (RCTs) of acupuncture for vascular dementia. METHODS: The RCTs of acupuncture for vascular dementia were systematically retrieved from the Cochrane Library, PubMed, EMbase, CNKI, SinoMed, VIP and Wanfang databases from the date of establishment to October 31, 2018. The reporting quality of RCT was evaluated based on the internationally-recognized Consolidated Standards for Reporting of Trials (CONSORT) statement and Standards for Reporting Interventions in Controlled Trials of Acupuncture (STRICTA). RESULTS: A total of 33 RCTs were included. According to the CONSORT statement, 12 items had a reporting rate of 0%, including important changes to methods after trial commencement, sample size, blind method, trial registry, etc.; 5 items had a reporting rate of below 10%, including trial design, type of randomization, random allocation sequence, randomization implementation and participant flow. The reporting rate was 36.36% for baseline data and 57.58% for randomization sequence generation. According to the STRICTA statement, the reporting rate was 21.21% for description of acupuncture depth, 60.61% for description of acupuncture response, 27.27% for description of additional intervention details and 0% for qualification of acupuncturists, respectively. CONCLUSION At present, the reporting quality of RCTs of acupuncture for vascular dementia is generally low. In the future, the RCTs of acupuncture for vascular dementia should be normatively reported according to the CONSORT statement and STRICTA statement.

Objective To construct homozygous aquaporin 9(AQP-9)

OBJECTIVE: To analyze the main factors affecting the positive results of acupuncture for chronic pain in English literature of randomized controlled trial (RCT), in order to provide reference for the design of acupuncture clinical research. METHODS: The RCTs of acupuncture for chronic pain published before March 26, 2020 were searched in PubMed, EMbase and Cochrane Library by computer. A total of 21 factors were analyzed by single-factor analysis, and the factors with statistically significant difference were selected for multivariate Logistic regression analysis. RESULTS: A total of 69 RCTs were included, including 47 RCTs (68.12%) with positive results and 22 RCTs (31.88%) with non-positive results. The multivariate Logistic regression analysis was performed with the three screened factors (publication year, treatment frequency and intervention form) selected by single-factor analysis, and the results showed that the positive results were related to the frequency of acupuncture treatment. The positive rate of RCT with frequency≥2 times a week was 3.24 times of that with frequency<2 times a week (OR=3.24, 95%CI =[1.07,9.83], P<0.05). CONCLUSION Acupuncture frequency may be the main factor affecting the positive results of RCT in English literature of acupuncture for chronic pain. More researches are needed in the future to explore the influence of acupuncture frequency on the curative effect.
