OBJECTIVETo observe the differences in onset time and the overall efficacy of the acupuncture therapy of dredging Governor Vessel and regulating mentality combined with fluoxetine and the fluoxetine for post-stroke depression(PSD).

METHODSSixty-three patients were randomly divided into an acupuncture intervention of dredging Governor Vessel and regulating mentality group(acupuncture and medication group, 33 cases) and a control group (medication group, 30 cases). In the medication group, 20 mg fluoxetine was used by oral administration, once a day at 7:00 in the morning, continuously for 4 weeks. In the acupuncture and medication group, based on the oral administration of fluoxetine, the acupuncture intervention of dredging Governor Vessel and regulating mentality was applied mainly at Baihui(GV 20), Fengfu(GV 16), Shenting(GV 24), Shuigou(GV 26), Dazhui(GV 14) and Shendao(GV 11), once a day, 6 times a week, continuously for 4 weeks. Twenty-four items in Hamilton Depression Scale(HAMD), modified Edinburgh Scandinavia Stroke Scale(MESSS) and activity of daily life scale(ADL, Barthel index, BI) were used before and after 2-week and 4-week treatment. The efficacy was compared between the two groups.

RESULTSAfter 2-week treatment, the HAMD score and the MESSS score in the acupuncture and medication group were obviously decreased and the BI score was apparently increased(all P<0. 01). In the medication group, however, the score of every scale was not statistically different from that before treatment(P'>0. 05). After 4-week treatment, HAMD scores and MESSS scores in the two groups were obviously decreased and the BI scores I were apparently increased(all P<0. 01). After 2-week and 4-week treatment, the HAMD scores and the MESSS scores in the acupuncture and medication group were lower than those in the medication group and the BI scores were higher than those in the medication group(P<0. 01, P<0. 05). The total effective rate of anti-depression (97. 0%, 32/33) the total effective rate of nerve function impairment(90. 9%, 30/33) and the total effective rate of daily life activity(97. 0% 32/33) in the acupuncture and medication group were better than 80. 0% (24/30), 80. 0%(24/30), 83. 3%(25/30) in the medication group(all P<0. 05).

CONCLUSIONThe acupuncture therapy of dredging Governor Vessel and regulating mentality could reduce the onset time of anti-depression medicine treatment of PSD and enhance the overall efficacy. Therefore, it enhances the clinical compliance.

OBJECTIVETo systematically evaluate acupuncture as a treatment for male infertility.

METHODSWe searched Chi na Biology Medical Database (CBM), Wan Fang Medical Information System, China National Knowledge Infrastructure (CNKI), VIP Information Resource System (VIP), and PubMed for published literature on acupuncture as a treatment for male infertility on May 1 2014. Based on the Standards for Reporting Interventions in Clinical Trials of Acupuncture (STRICTA), we evaluated the quality of the reports, conducted meta-analysis on the identified studies via RevMan5.2, and assessed the quality of the evidence in the literature by Grading of Recommendations Assessment, Development, and Evaluation (GRADE).

RESULTSA total of 12 studies involving 2,177 patients were included, the quality of which was evaluated as mediocre. With regard to the cure rate, acupuncture was comparable to traditional Chinese medicine (TCM) (P > 0.05) but better than Western medicine (RR = 4.00, 95% CI 1.63 to 9.82, P < 0.01) while acupuncture + TCM was better than either TCM (RR = 1.77, 95% CI 1.20 to 2.60, P < 0.01) or Western medicine used alone (RR = 2.73, 95% CI 1.51 to 4.93, P < 0.01), and acupuncture + Western medicine was better than Western medicine alone (RR = 1.88, 95% CI 1.17 to 3.02, P = 0.01). The combined use of acupuncture, ear pressure, TCM, and Western medicine showed a higher cure rate than the combination of TCM and Western medicine (RR = 3.45, 95% CI 2.90 to 4.11, P < 0.01). In therapeutic effectiveness, acupuncture was comparable to TCM (P > 0.05) but superior to Western medicine (RR = 1.41, 95% CI 1.12 to 1.71, P < 0.01), acupuncture + TCM was superior to either TCM (RR = 1.14, 95% CI 1.05 to 1.23, P < 0.01) or Western medicine alone (RR = 1.43, 95% CI 1.22 to 1.67, P < 0.01), and acupuncture + Western medicine was superior to Western medicine alone (RR = 1.25, 95% CI 1.05 to 1.49, P = 0.01). In improving sperm concentration, acupuncture was as effective as TCM (P > 0.05) and sham acupuncture (P > 0.05) but outdid Western medicine (RR = 27.00, 95% CI 24.27 to 29.73, P < 0.01) and acupuncture + TCM outdid either TCM (RR = 14.65, 95% CI 7.58 to 21.72, P < 0.01) or Western medicine alone (RR = 1.04, 95% CI--1.43 to 3.51, P > 0.05). In improving grade a sperm, acupuncture exhibited a similar effect to TCM (P > 0.05) and sham acupuncture (P > 0.05), and acupuncture + TCM was more effective than TCM alone (RR = 7.78, 95% CI 3.51 to 12.23, P < 0.01) but equally effective as Western medicine (P > 0.05). In elevating the level of grade a + b sperm, acupuncture + TCM excelled either TCM (RR = 11.00, 95%, CI 3.17 to 18.82, P < 0.01) or Western medicine alone (RR = 12.22, 95% CI 6.87 to 17.57, P < 0. 01), while acupuncture produced a comparable effect with sham acupuncture (P > 0.05). As for the quality of the included studies, only 3 conclusions of the 23 meta-analyses were assessed to be of average quality, while the others of poor or extremely poor quality. Therefore, the recommendation grade of the conclusions was low.

CONCLUSIONFor the treatment of male infertility, acupuncture is reported to be equally effective as TMC and more effective than Western medicine, and its effectiveness is enhanced when applied in combination with either TCM or Western medicine. Acupuncture is distinctively efficacious in improving sperm quality. Nevertheless, the overall quality of the included studies is low.

OBJECTIVETo study the anti-platelet GPVI single chain Fv phage antibody which can inhibit the aggregation function of platelet by using phage antibody library technology.

METHODSITP patients with anti-platelet GPVI autoantibody that could inhibit the aggregation function of platelet were screened by MAIPA assay and platelet aggregation test. The gene fragments of heavy chain and light chain variable region (VH and VL) of immunoglobulin were amplified by RT-PCR from peripheral blood lymphocytes mRNA of the screened patients. The VH and and VL fragments were linked through a DNA linker encoding the peptide (Gly4Ser)3 to construct single chain Fv (ScFv) gene. The ScFv gene was digested with SfiI/NotI restriction enzymes and cloned into the pHEN2 phage display vector, then electrically transformed to E. coli TG1. The TG1 containing ScFv-pHEN2 was rescued by helper phage M13K07 to produce ScFv phage antibody. The anti-platelet GPVI phage ScFv antibody was enriched and purified. The effect of the phage antibody on platelet aggregation function was studied.

RESULTSOf 806 chronic ITP patients, 11 (1.36%) were positive for anti-platelet GPVI autoantibody and 2 (0.24%) patients'plasma significantly inhibited the collagen induced platelet aggregation. The length of VH and VL fragments was about 380 to 400 bp, and were successfully formed ScFv fragments of about 800 bp by DNA linker. After cloning ScFv to phagemid vector pHEN2 and transforming ScFv-pHEN2 to TG1, 4.1x10(7) clones were obtained. After M13K07 rescue, 2.62x10(10) cfu/ml ScFv phage antibodies were produced. The purified anti-platelet GPVI ScFv phage antibody inhibited the collagen induced platelet aggregation.

CONCLUSIONAnti-platelet GPVI ScFv phage antibody produced by phage antibody library technology can inhibit the aggregation function of platelet.

BACKGROUNDAblation of complex fractionated atrial electrograms (CFAE) is an important adjunctive therapy in atrial fibrillation (AF). The present study was to elucidate the substrate underlying CFAE.

METHODSNine adult mongrel dogs were involved in the present study. AF was induced through rapid atrial pacing with vagosympathetic nerve stimulation. CFAE was recorded during AF. Ablation was performed at CFAE sites. Based on the location of the ablation scar, the atrial specimens were divided into CFAE and non-CFAE sites. Serial sections of the atrium were stained respectively with hematoxylin-eosin (HE) and the general neural marker protein gene product 9.5 (PGP9.5). We compared the characteristics of the myocardium and the ganglionated plexus (GPs) distribution between the CFAE and non-CFAE sites.

RESULTSThe myocardium of non-CFAE sites was well-organized with little intercellular substance. However, the myocardium in the CFAE site was disorganized with more interstitial tissue ((61.7 ± 24.3)% vs. (34.1 ± 9.2)%, P < 0.01). GPs in the CFAE site were more abundant than in non-CFAE sites ((34.45 ± 37.46) bundles/cm(2) vs. (6.73 ± 8.22) bundles/cm(2), P < 0.01).

CONCLUSIONThe heterogeneity of the myocardium and GPs distribution may account for the substrate of CFAE and serve as a potential target of ablation.

The present study was designed to evaluate the protective effects of ethanol extracts of Rabdosia japonica var. glaucocalyx (Maxim.) Hara (RJ) on lipopolysaccharide (LPS)-induced acute lung injury (ALI) in mice and the possible underlying mechanisms of action. The mice were orally administrated with RJ extract (16, 32 or 64 mg(kg(-1)) daily for consecutive7 days before LPS challenge. The ung specimens and the bronchoalveolar lavage fluid (BALF) were collected for histopathological examinations and biochemical analyses. Pretreatment with RJ significantly enhanced superoxide dismutase (SOD) activity and reduced the wet-to-dry weight (W/D) ratio, the levels of nitric oxide (NO) and protein leakage, and myeloperoxidase (MPO) activity in mice with ALI, in a dose-dependent manner. RJ reduced complement deposition and significantly attenuated LPS-induced ALI by reducing productions of inflammatory mediators, such as tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-1β (IL-1β). The results demonstrated that RJ may attenuate LPS-induced ALI via reducing the production of pro-inflammatory mediators, and reducing complement deposition and radicals.

Residue of Mori Cortex was studied to optimize its enzymatic hydrolysis process, and explore its potential as a carbon source for biochemistry and biofuel production. The cellulose content of diluted acid pretreated (DAP) and non-pretreated from Mori Cortex were measured in this study, and the results showed that the cellulose content of DAP and non-pretreated from Mori Cortex were 52.5% and 47%, respectively. This higher cellulose content indicated that residue of Mori Cortex had the potential to act as a carbon source for biochemistry and biofuel production. Enzymatic hydrolysis of pretreated and non-pretreated from Mori Cortex was conducted under different enzyme loading amount. 40 FPU·(g DW）⁻¹ enzyme loading was determined as the optimal amount by comparing the yield of sugar and the rate of enzymolysis. Under this condition, the concentrations of glucose, xylose, arabinose sugar were 23.82, 4.84, 3.6 g·L⁻¹, and the corresponding enzymatic hydrolysis rate was 45.33% which was 2.3 times higher than that of non-pretreated from Morus alba residues. Fed-batch enzymatic hydrolysis was conducted finally to get higher sugar yield, and the final glucose concentration reached up to 38 g·L⁻¹ with the enzymatic hydrolysis rate of 36.19%. The results indicated that Mori Cortex residue had higher cellulose and hemicellulose contents, so it had the potential to become a carbon source to produce the bio-chemicals and biofuels. Through enzymatic hydrolysis, it can be converted into microbial available monosaccharides; and through fermentation, it can be converted into high value-added chemicals, biofuels, etc., to solve the problem of residue pollution, and achieve the sustainable development and greening of Chinese pharmaceutical production process.

OBJECTIVETo evaluate the safety of recombinant human interferon alpha-2b for nasal spray for the prevention of SARS and other upper respiratory viral infections.

METHODSField epidemiologic evaluation was conducted, the design was randomized and had a synchronously parallel control group. In the study, the drugs were given for five days and all subjects were followed up for ten days.

RESULTSDuring the period of using interferon, body temperature of the experimental group was normal compared to the control group. Experimental group had more influenza-like symptoms than the control group (P < 0.05), such as headache (4.83%-7.09%), dizziness (7.17%-11.63%), lassitude (8.55%-15.06%), muscular soreness (4.43%-7.09%), pharynx dryness (12.10%-17.85%), angina (6.25%-8.72%), abdominal pain (2.30%-5.50%) and diarrhea (2.45%-5.66%). Most of side effects reached their peak with in the first 3 days. Except for pharynx dryness, the incidences of all other side effects declined after completion of the use of the trial drug, and incidences of some symptoms in experimental group were lower than those of the control group. There were no significant differences in the symptoms of cough and expectoration between the experimental group and the control group. The incidence of exanthem in the control group was significantly higher than that in the experimental group. The side effect of bloody nasal mucus was not observed in experimental group, which had been reported by other authors in several volunteer studies.

CONCLUSIONUsing recombinant human interferon alpha-2b for nasal spray could lead to some influenza-like symptoms, however, all those symptoms were mild , reversible, and relieved after completion of the use of the trial drug. No serious side effects were found during the period of following up. The authors conclude that the drug is safe.
