Cyclic diguanylate (c-di-GMP) is a bacterial second messenger of growing recognition involved in the regulation of a number of complex physiological processes. In combinations to the related progress of Xanthomonas oryzae pv. oryzae, the causing agent of bacterial blight of rice in our lab, this review describes (1) the biosynthesis and hydrolysis of c-di-GMP and several mechanisms of regulation of c-di-GMP metabo-lism, (2) the contribution of c-di-GMP to regulating virulence, motility and biofilm formation, processes that affect pathogenesis of many bacteria, and (3) ways in which c-di-GMP may mediate these regulatory effects.

OBJECTIVETo observe the effect of Yangxue Qingnao Granule (YQG) on the expression of CD11b in CA1 region of hippocampus of vascular dementia rats, and to explore its regulation on microglias.

METHODSTotally 144 SD rats were randomly divided into the sham-operation group, the vascular dementia model group (model), and the YQG treated group (treated). The vascular dementia rat model was prepared by modified Pulsinelli's four-vessel occlusion. Rats in the sham-operation group and the model group were administered with normal saline -(at the daily dose of 10 mL/kg) by gastrogavage, while those in the treated group were administered with YQG (0.32 g/mL, at the daily dose of 10 mL/kg) by gastrogavage. All administration was performed once per day for 8 successive weeks. The expression of CD11b in CA1 region of hippocampus of vascular dementia rats was detected at week 1, 2, 4, and 8, respectively.

RESULTSCompared with the sham-operation group, the expression of CD11b in CA1 region of hippocampus of vascular dementia rats were significantly enhanced in the model group at each time point (P < 0.01). Compared with the model group, the expression of CD11b in CA1 region of hippocampus of vascular dementia rats significantly decreased in the treated group at each time point (P < 0.01), especially at week 2.

CONCLUSIONObvious activation and proliferation of microglias could be seen in CA1 region of hippocampus of vascular dementia rats, and YQG could inhibit activation and proliferation of microglias.

OBJECTIVETo observe the effects of Danlou Tablet (DT) on inflammatory reaction, and expressions of lipoprotein-associated phospholipase A2 (LP-PLA2), secretory phospholipase A2 (sPLA2), and to analyze potential mechanisms.

METHODSForty male Wistar rats were randomly and equally divided into five groups, i.e., the normal control group, the model group, the Western medicine (WM) group, the low dose DT group, the high dose DT group, 8 in each group. Rats in the normal control group were fed with basic forage for 12 successive weeks, while AS rat model was established in rats of the other four groups by feeding high fat and sugar forage plus intraperitoneal injection of vitamin D₃. Normal saline, atorvastatin calcium suspension (at the daily dose of 1.8 mg/kg), low dose DT suspension (at the daily dose of 450 mg/kg), and high dose DT suspension (at the daily dose of 900 mg/kg) were administered to rats in the model group, the WM group, the low dose DT group, the high dose DT group respectively by gastragavage for 8 successive weeks. The general condition of all rats was observed. Rats were sacrificed after gastric administration and their serum collected. Serum levels of lipids (TC, TG, HDL-C, LDL-C) and inflammatory factors [IL-6, TNF-α, monocyte chemoattractant protein 1 (MCP-1), oxidized low-density lipoprotein (ox-LDL), lipoprotein-associated phospholipase A2 (LP-PLA2), secretory phospholipase A2 (sPLA2)] were detected. Pathological changes of thoracic aorta were observed by HE staining. Protein and gene expressions of LP-PLA2 and sPLA2 in thoracic aorta were measured by Western blot and real-time fluorescent quantitative PCR respectively.

RESULTSCompared with the normal control group, rats in the model group were in low spirits and responded poorly. Typical atherosclerotic plaque could be seen in thoracic aorta of rats in the model group. Serum levels of TC, TG, LDL-C, IL-6, TNF-α, MCP-1, ox-LDL, LP-PLA2, and sPLA2 significantly increased (P < 0.05); protein and gene expressions of LP-PLA2 and sPLA2 in rat thoracic aorta increased (P < 0.05) in the model group. After 8 weeks of intervention, rats in 3 medication groups appeared active, and HE staining showed subsidence of plaque in rat thoracic aorta. Compared with the model group, serum levels of TC, TG, LDL-C, IL-6, TNF-α, MCP-1, ox-LDL, and LP-PLA2 decreased in 3 medication groups (P < 0.01, P < 0.05); serum sPLA2 level decreased, protein and mRNA expressions of LP-PLA2 and sPLA2 in rat thoracic aorta decreased in the WM group (P < 0.01, P < 0.05); protein and mRNA expressions of LP-PLA2 in rat thoracic aorta significantly decreased in the low dose DT group (P < 0.01, P < 0.05), and those of LP-PLA2 and sPLA2 decreased in the high dose DT group (P < 0.01, P < 0.05).

CONCLUSIONDT could fight against inflammatory reaction and AS possibly through inhibiting LP-PLA2 expression and reducing ox-LDL production.

Objective To investigate the effect of rehabilitation training on the sensory dysfunction after stroke.Methods Fifty three stroke patients with sensory dysfunction were randomly divided into 2 groups:a con- trol group and a treatment group.The control group composed of 25 patients was intervened with conventional treat- ment,while the treatment group composed of 28 patients with sensory training in addition to the conventional treat- ment.The effect of rehabilitation training of the two groups was evaluated by Fugl-Meyer Assessment (FMA) before and afer treatment.Results The FMA scores of patients of both groups increased significantly after 2 months of treatment (P

OBJECTIVETo identify a novel VNTR in C6orf37 and to detect the C6orf37 VNTR polymorphism distribution in Chinese population.

METHODSRT-PCR and sequencing were conducted to identify VNTR alleles in the variable region of C6orf37.SSLP and DHPLC were applied in detecting the VNTR genotypes in 166 Chinese individuals.

RESULTA novel VNTR sequence was found in the second exon of C6orf37, which was composed of 15 base pairs encoding 5-amino-acid (G-G-D-F-G). The repeat times ranged from 3 to 5. There were three common alleles containing three repeats (a), four repeats (b) and five repeats (c), respectively, which produced three homozygotes (a/a, b/b and c/c) and three heterozygotes (a/b, a/c and b/c). The frequency of a, b, c alleles were 0.145, 0.304, 0.551, respectively in Chinese population. Heterozygosity (H) was 0.583. Polymorphism information content (PIC) was 0.510. The screened result of DHPLC was consistent with that of SSLP.

CONCLUSIONA novel highly polymorphic VNTR in C6orf37 exists in Chinese population. DHPLC is the most efficient technique for screening VNTR polymorphism.

OBJECTIVETo evaluate clinical efficacy of suture anchors in treating acute injuries of medial collateral ligament (MCL) of knee at degree III.

METHODSTwenty-seven patients with degree III acute MCL injuries of knee were treated with suture anchors from January 2007 to June 2011. There were 15 males and 12 females, aged from 19 to 56 (averaged 32.6) years old. The time from injury to operation was 3 to 10 days, averaged 6 days. Symptoms and physical signs before and after treatment were observed, Lysholm scoring were used to evluated clinical efficacy.

RESULTSAll patients were followed up from 16 to 30 months with an average of 21.6 months. The stability of knee joints was good in all patients. Abduction stress test was negative when the knee joint was straightened at 0 degrees and flexed at 30 degrees. The average degree of flexed knee (67.00 +/- 5.80) degrees preoperatively was lower than that of postoperatively (136.50 +/- 6.30) degrees at 1 year. According to Lysholm scoring, preoperative scores ranged from 30 to 43 points, averaged 36.46 +/- 1.48; 1 year after operation ranged from 87 to 100 with an average of 91.50 +/- 3.80 and higher than postoperative. Twenty patients got an excellent results, 5 good and 2 fair.

OBJECTIVETo evaluate clinical effect and safety of floating needle therapy and duloxetine in treating patients with persistent somatoform pain disorder (PSPD).

METHODSTotally 108 PSPD patients were randomly assigned to the floating needle treatment group, the duloxetine treatment group, and the placebo treatment group, 36 in each group. Patients in the floating needle treatment group received floating needle therapy and placebo. Those in the duloxetine treatment group received duloxetine and simulated floating needle therapy. Those in the placebo treatment group received the placebo and simulated floating needle therapy. All treatment lasted for six weeks. Efficacy and adverse reactions were evaluated using Simple McGill pain scale (SF-MPQ) and Treatment Emergent Symptom Scale (TESS) before treatment and immediately after treatment, as well as at the end of 1st, 2nd, 4th, and 6th week of treatment, respectively. Hamilton Depression Scale (HAMD, 17 items), Hamilton Anxiety Scale (HAMA) were assessed before treatment and at the end of 1st, 2nd, 4th, and 6th week of treatment, respectively. Patients in the floating needle treatment group and the duloxetine treatment group with the total reducing score rate of SF-MPQ in Pain Rating index (PRI) ≥ 50% after 6 weeks' treatment were involved in the follow-up study.

RESULTS(1) Compared with the same group before treatment, SF-MPQ score, HAMD score and HAMA total scores all decreased in all the three groups at the end of 1st, 2nd, 4th, and 6th week of treatment (P < 0.05, P < 0.01). Besides , each item of SF-MPQ significantly decreased immediately after treatment in the floating needle treatment group (P < 0.01). Compared with the placebo treatment group, SF-MPQ, HAMD, and HAMA total score in the floating needle treatment group significantly decreased after 1, 2, 4, and 6 weeks of treatment (P < 0.05, P < 0.01). SF-MPQ score, HAMD score and HAMA total score in the duloxetine treatment group also significantly decreased after 2, 4, and 6 weeks of treatment (P < 0.05, P < 0.01). (2) There were 3 patients (8.3%) who had adverse reactions in the floating needle treatment group, 17 (50.0%) in the duloxetine treatment group, and 7 (21.2%) in the placebo treatment group. Compared with the placebo treatment group, the incidence of adverse reaction increased in the duloxetine treatment group (χ² = 6.04, P < 0.05). Besides, it was higher in the duloxetine treatment group than in the floating needle treatment group (χ² = 14.9, P < 0.05). (3) There were 19 patients in the floating needle treatment group and 17 patients in the duloxetine treatment group involved in the follow-up study. Compared with 6 weeks after treatment, no significant difference was observed at 3 and 6 months after treatment in the score of SF-MPQ, HAMD, and HAMA in the floating needle treatment group and the duloxetine treatment group. No significant difference was observed between the two groups (P > 0.05). There were 5 patients (29.4%) who had adverse reactions in the duloxetine treatment group, and no adverse reactions were observed in the floating needle treatment group. The adverse reaction rate was significantly different between the two groups (χ² = 4.26, P < 0.05).

CONCLUSIONSFloating needle therapy and duloxetine were effective in treatment of patients with PSPD. However, floating needle therapy could relieve pain more rapidly than duloxetine, with obviously less adverse reactions.
