OBJECTIVE: To observe the effect on swallowing function in patients with post-stroke dysphagia treated with nape cluster acupuncture and the immediate effect of acupuncture at Fengchi (GB 20). METHODS: A total of 60 patients with post-stroke dysphagia were randomized into an observation group and a control group, 30 cases in each one.On the basis of conventional western medication treatment, swallowing function training was applied in the control group, once a day.On the base of the treatment as the control group, nape cluster acupuncture was applied at Fengchi (GB 20), Tianzhu (BL 10), Wangu (GB 12), Lianquan (CV 23), Panglianquan (Extra), Jinjin (EX-HN 12) and Yuye (EX-HN 13) in the observation group, once a day. Additionally, pricking blood was applied at Jinjin (EX-HN 12) and Yuye (EX-HN 13), 2 times a week. The treatment was given 30 min each time, a week as one course and 4 courses were required. Before and after treatment, the standardized swallowing assessment (SSA) score and video fluoroscopic swallowing study (VFSS) score were compared in the two groups. The ultrasonic diagnostic device of swallowing and surface electromyography were used to observe the immediate effect on swallowing related muscles of acupuncture at Fengchi (GB 20). RESULTS: Compared before treatment, the SSA scores were reduced after treatment in the two groups (<0.05), and the change of the observation group was larger than the control group (<0.05). Compared before treatment, the VFSS scores were increased after treatment in the two groups (<0.05), and the change of the observation group was larger than the control group (<0.05). Acupuncture at Fengchi (GB 20) immediately increased the amplitude of submental muscles and infrahyoid muscles in the observation group (<0.05), the geniohyoid muscle movement time was reduced and geniohyoid muscle displacement was increased (<0.05). CONCLUSION On the base of the routine treatment, nape cluster acupuncture could improve swallowing function in patients with post-stroke dysphagia. Acupuncture at Fengchi (GB 20) could immediately affect swallowing related muscles, improve muscle amplitude and reduce swallowing time.

AIM To investigate the protective effects of Miaoling Natto Capsules (MNC) on myocardial ischemia-reperfusion injury (MIR) in rats.METHODS Forty-eight healthy male Sprague-Dawley (SD) rats randomly divided into sham group,model group,positive control group (propranolol),MNC groups (low dose,medium dose,and high dose groups) underwent corresponding 7-day oral administration at a frequency of twice daily (rats of the sham group and the model group were dosed with saline water at 1 mL/100 g).Anesthetized by 8％ chloral hydrate,rat models were made by left anterior descending coronary artery ligation,30 min coronary occlusion followed by 3 h of reperfusion for ST segments and T waves monitoring,and rats in the sham group were performed opening and suture procedures.The rats had their serum levels of acetic transaminase (AST),lactate dehydrogenase (LDH),creatine kinase isoenzyme (CK-MB),cardiac troponin-Ⅰ (cTn-Ⅰ),superoxide dismutase (SOD),malondialdehyde (MDA),and tumor necrosis factor-α (TNF-α) detected,real time ECG changes monitored and myocardial infarction area assessed by TTC.RESULTS Compared with the sham group,the model group was observed with markedly elevated ST segments or high T waves rise,significantly increased activities of CK-MB,LDH,AST and the content of cTnⅠ,MDA,TNF-α,and decreased activity of SOD (P ＜ 0.01 or P ＜ 0.001).Compared with the model group,the positive control group and the low,medium and high dose MNC groups achieved controlled ST segments elevation or greater T waves amplitude,significantly decreased activities of CKMB,LDH,AST and the content of cTnⅠ,MDA,TNF-α increased activity of SOD (P ＜0.01 or P ＜0.05) and mycocardial infact range reduction (P ＜ 0.001).CONCLUSION MNC is protective to rats with myocardial ischemia-reperfusion injury.

The dialysis method was employed to load adriamycin into the micelles formed by temperature and pH sensitive polyhistidine-co-DL-lactide-co-glycolide-polyethylene glycol poly DL-lactide-co-glycolide-co-histidine (OLH-b-PLGA-b-PEG-b-PLGA-b-OLH). The critical micelle concentration (CMC) of the copolymer was measured with pyrene fluorescent probe method under different temperatures. The entrapment rate and drug-loading rate were determined with dialysis method. The diameter, morphology and surface potential of the copolymer micelles were investigated by corresponding instruments, respectively. The release behavior of adriamycin from copolymer micelles and the pH sensitivity were studied. The CMC of the copolymers ranged from 0.022 4 to 0.001 7 microg x mL(-1). The entrapment rate and drug-loading rate were 92.8% and 15.7%, respectively. The micelles have a mean diameter of (61.7 +/- 13.4) nm, and zeta potential was -9.88 mV. The in vitro adriamycin release rate increased with the pH dropping from 7.4 to 5.0. The results indicated that the CMC of the copolymers decreased as the raising of temperature, drug release behavior from the micelles possessed clearly pH sensitivity, and the copolymers may have a potential in targeted delivery system for anticancer drugs.

Objective: To investigate the coagulation function in patients with acute-on-chronic liver failure (ACLF) patients using thromboelastography (TEG), and to comprehensively and dynamically evaluate patients’ bleeding and coagulation status. Methods: The clinical data of ACLF patients were collected, and TEG was used to evaluate whole blood clotting kinetics in these patients. Routine biochemical parameters were measured, and complications were evaluated. The t-test was used for comparison of continuous data, the chi-square test was used for comparison of categorical data, and the Pearson correlation coefficient was used for correlation analysis. P < 0.05 was considered statistically significant. Results: A total of 60 patients (39 male and 21 female patients) were enrolled, with a mean age of 47.20±16.20 years. The TEG results showed that all patients had normal thrombokinetics, but TEG parameters were correlated with coagulation function, markers of systemic inflammatory response syndrome, laboratory markers, and prognosis. The patients with a higher R value had higher risks of infection (6.23±2.91 vs 4.74±1.12, P = 0.009), hepatorenal syndrome (5.64±2.54 vs 3.21±1.43 P < 0.01), and bleeding (6.71±3.51 vs 4.80±1.63, P = 0.01), and the patients with a lower K value (0.72±1.36 vs 1.64±1.43, P = 0.02), an increased α-angle (63.33°±10.02° vs 56.62°±12.13°, P = 0.03), and an increased MA (56.83±11.07 vs 50.40±10.81, P = 0.03) had increased risks of hepatic encephalopathy. Conclusion ACLF patients have low coagulation function, and TEG truly reflects the "rebalance" status of this low level. Abnormal TEG parameters suggest increased risk of complications in these patients, indicating a poor prognosis.

OBJECTIVE: To investigate polymorphism distribution of the 5 Y-SNP loci in Jinan Han population, and evaluate their potential in forensic application. METHODS: Genotyping of 5 Y-SNP loci (M89, M9, M122, M134, M95) were executed in the sample of 103 unrelated Chinese male individuals in Jinan Han population by using fragment length discrepant allele specific PCR (FLDAS-PCR). RESULTS: In 5 Y-SNP loci, genetic polymorphism were identified in Jinan Han population, and the ranges of gene diversity(GD) were 0.093 3-0.491 2. Twenty different haplotypes were observed and the haplotypes diversity (HD) was 0.867 9. Six different haplogroups were detected according to international association of Y chromosome nomenclature. CONCLUSION Five Y-SNP loci and their haplogroups in Jinan Han population are highly polymorphic, which can provide more information for the genetic structure analysis and forensic genetics research in the region.

OBJECTIVETo investigate the effects of immature dendritic cells (imDC) expressing chemokine receptor-7 (CCR7) on acute graft-versus-host disease (aGVHD) in allogeneic bone marrow transposed (allo-BMT) mouse model.

METHODSWe constructed the lentiviral vectors carrying mouse CCR7 gene and infect imDC effectively in vitro. GVHD model was established with C57BL/6(H-2b) donor mice and BALB/c (H-2d) recipient mice. After irradiation, recipients were injected with donor bone marrow and spleen cells along with CCR7-modified dendritic cells. Mice were randomized into irradiation, transplant control, pXZ9-imDC (empty vector control) and CCR7-imDC groups. Survival, GVHD score, histopathological analysis and plasma levels of inflammatory cytokines were observed.

RESULTSThe mean survival in irradiation, transplantation, pXZ9-imDC and CCR7-imDC groups were (8.20±1.48)d, (12.20±2.78)d, (20.70±6.01)d and (27.5±7.55)d respectively. The survival in CCR7- imDC group was significantly improved compared with other groups (P<0.05). GVHD scores in transplantation, pXZ9-imDC and CCR7-imDC groups were (6.90±1.66), (5.60±0.97) and (4.10±1.79) respectively. CCR7-imDC group had significantly lower GVHD score and minor tissue damages shown by histopathological analysis than the other groups. Plasma IFN-γ level increased and reached the peak at +10 day in transplant group, while it gradually decreased in pXZ9-imDC and CCR7-imDC groups, and then reached the nadir at +20 day post-allo-BMT, with the lowest level in CCR7-imDC group (P<0.01). Plasma IL-4 decreased in transplant group, while it gradually increased in pXZ9-imDC and CCR7-imDC groups and reached the highest level at + 10 day in CCR7- imDC group (P<0.01). The 95%-100% of H-2b positive cells in recipient mice on + 30 day post-allo-BMT demonstrated the complete donor- type implantation.

CONCLUSIONGenetically modified immature DC by CCR7 gene could alleviate damages by GVHD and prolong survival of recipient mice after allo-BMT.
