Objective To study the type variation of microglial activation in spinal dorsal horn of rats after sciatic nerve injury.Methods Healthy adult male Sprague-Dawley rats were randomly divided into the control and experimental groups, 24 rats in each group.The experimental group underwent ligation of sciatic nerve trunk to generate nerve injury in the rats.The pain behavior in the rats was measured at the 1th, 7th and 14th postoperative days, and the changes of microglial activation in the rat lumbar spinal cord dorsal horn was detected by immunofluorescence staining.qRT-PCR assay was used to validate the activation trends of M1 and M2 types of microglia cells.Results No significant changes were found in the microglial cells in the spinal cord dorsal horn of rats in the sham-operation group during 14 days after operation.In the sciatic nerve ligation group at 1 day after operation, no significant change was observed in the number of microglial cells, but the expression of marker of M1 microglia was significantly increased.At 7 and 14 days after operation, the number of microglial cells and the expression of M1 microglia marker in the spinal cord dorsal horn were increased significantly.Conclusions Microglia activation in the spinal dorsal horn starts at the first day after sciatic nerve injury, and lasts at least for two weeks after the operation.M1 microglia activation dominates during this period.

Objective To observe the effect of catechol-O-methyltransferase inhibitor (COMTI) tolcapone on levodopa-treated patients with Parkinson's disease (PD) and on the motor function fluctuation, and safety taking this drug.Methods50 PD patients treated with levodopa were divided into the trial group and control group with 25 cases in each group. The patients in the trial group were given tolcapone 100 mg three times per day. The cases in the control group were given placebo with the same dose. The hepatic function of the patients was examined every month after administration. The time variety of patients' motor function fluctuation was recorded by the diary. The time of clinical observation was 6 months.ResultsThe UPDRS scores of the trial group in the first and second months after taking tolcapone were not significantly different from that of the control group ( P>0.05), but scores of the third to sixth months were significantly different from that of the control group ( P<0.05～0.01). There was a significant difference between UPDRS scores of the trial group before and after treatment ( P<0.01～0.001). The Honhe-Yahr scores of the trial group in the first and second months after treatment were not significantly different from that before treatment ( P>0.05), but scores of the third to sixth months were significantly different from that before treatment ( P<0.05). The motor function fluctuation of the patients in the trial group improved significantly after treatment ( P<0.05). The numbers of the cases had dry mouth, nausea and astriction were 3 respectively; those had acratia, insomnia and diarrhea were 2 respectively; those had muscular soreness, abdominal distention, hidrosis and fidget were 1 respectively. All adverse effects had a little influence to administration. The hepatic function of all patients had no significant change.ConclusionTolcapone can increase the curative effect of PD patients treated with levodopa and improve the motor function fluctuation, and is safety after taken.

Objective To investigate the utility value of monoexponential and biexponential DWI in the differential diagnosis between benign and malignant liver neoplasms.Methods Seventy three patients with pathologically or clinically confirmed liver mass,were analyzed retrospectively and categorized into benign and malignant groups between January 2013 and October 2013.Malignant group included 46 patients with 53 lesions,while 27 patients in benign group had 35 lesions.All patients underwent MR examinations on 3.0T system (GE 750).Conventional MR T1WI,T2WI,DWI(b=0,800 s/mm2) (to obtain ADC with monoexponential modeling),multi-b value DWI(b=0,20 50,100,200,400,600,800 and 1 200 s/mm2) (to obtain Slow-ADC,Fast-ADC,f with biexponential modeling) and dynamic enhancement were performed.The ADC,Slow-ADC,Fast-ADC and f mean values of benign and malignant liver neoplasms were measured and analyzed by using independent samples t test.Diagnostic efficacy of these parameters in malignant group was evaluated by using receiver operating characteristic curve,with histopathologic findings as the gold standard.Results ADC,Slow-ADC,Fast-ADC and f of malignant group were lower than those of benign group [ADC:(1.79±0.35)× 10-3 mm2/s vs (1.16±0.36) × 10-3 mm2/s; Slow-ADC:(1.67±0.25) × 10-3 mm2/s vs(0.94±0.22)×10-3mm2/s; Fast-ADC(72.40±23.70)×10-3mm2/s vs(34.62±17.43)×10-3mm2/s; and f:(33.59± 11.77)％ vs (22.28±8.97)％ in benign and malignant groups,respectively).Significant inter-group difference was observed in ADC,Fast-ADC,Slow-ADC and f (t=0.89,14.77,8.96 and 5.47,respectively and P＜0.05).The areas under the ROC curve (AUC) of ADC,Slow-ADC,Fast-ADC and fwere 0.938,0.974,0.895 and 0.789,respectively.The sensitivity and specificity of ADC,Slow-ADC,Fast-ADC and fwere 90.6％ (48/53),96.2％ (51/53),90.6％ (48/53) and 90.6％ (48/53) and 85.7％ (30/35),91.4％ (32/35),82.9％ (29/35) and 57.1％ (20/35)respectively for differentiating benign from malignant hepatic lesions.Conclusion ADC obtained with mono-exponential modeling and Fast-ADC,Slow-ADC,f obtained with biexponential modeling are useful parameters in distinguishing benign and malignant hepatic lesions,among which slow-ADC demonstrates the highest diagnostic efficacy.

Objective: The characteristics and differences of the general notice between the Chinese Pharmacopoeia and the Japanese Pharmacopoeia were investigated to provide references and suggestions for the compilation of the Chinese Pharmacopoeia.
Methods: From the perspective of frame structure and main contents, the general notice between the Chinese Pharmacopoeia and the Japanese Pharmacopoeia was compared.
Results: Each volume of the Chinese Pharmacopoeia had its general notice, including 34 to 48 items and 10 to 12 chapters based on different varieties collected in each volume. The Japanese Pharmacopoeia had 49 items not arranged by chapters. There are many differences on the general notice between the Chinese Pharmacopoeia and the Japanese Pharmacopoeia, such as the definitions and expressions of names, determination of appearance, revision rules, risk assessment and quality control conception. The framework of the general notice in the Chinese Pharmacopoeia was clear, the content was specific and the operation was friendly. The term description of the general notice in the Japanese Pharmacopoeia was concise, and some terms need to be implemented under the guidance of professional knowledge.
Conclusion: In light of comparative study, every volume’s general notice of the Chinese Pharmacopoeia has its own characteristics. By integrating advanced analytical technique, combining the requirements with laws and regulations, and optimizing content and terms, all volume’s general notice could be explored to be coordinated and unified.

The incidence of liver disease is increasing year by year. Due to the complex predisposing factors and unclear pathogenesis of liver diseases, the cure rate is still not ideal, so it is urgent to clarify its mechanism to find more effective therapeutic targets and drugs. Long non-coding RNA (lncRNA), as a non-coding RNA with a length of more than 200 nt, is a research hotspot in liver diseases in recent years. Focusing on the main signal transduction pathways in liver diseases, this review mainly summarizes the latest research progress of lncRNA in regulating liver disease-related signaling pathways, and elaborates that lncRNAs participate in various physiological processes such as cell proliferation, apoptosis, invasion, and migration by regulating key signaling pathways in liver diseases, thereby promoting the occurrence and development of liver diseases. This review provides new ideas for studying the mechanism of liver diseases, and new directions for finding new targets and biomarkers for the treatment of liver diseases.

Objective To identify the diagnostic value of ADC combined with DWI in benign lesions and malignant lesions of testis. Methods 35 patients with testicular lesions confirmed by operation and pathological examination in our hospital were analyzed retrospectively, including 18 benign lesions and 17 malignant lesions.The mean ADC values of normal tissue and parenchyma of testicular lesions were measured and statistically analyzed by K ruskal-W allis test,and receiver operating characteristic(ROC)curve was delineated. The optimum ADC value for differential diagnosis of malignant testicular lesions was analyzed and determined.Results In 33 cases of normal testicular tissue DWI showed homogeneous high signal,and mean ADC was(1.137 ± 0.119)×10-3mm2/s.18 cases of benign lesions mostly showed unrestricted diffusion,and mean ADC was(1.104 ± 0.463)×10-3mm2/s.In 17 cases of malignant lesions DWI showed high signal,and mean ADC was(0.778 ± 0.198)×10-3mm2/s.The comparison of ADC mean values between malignant testicular lesions and normal tissue as well as benign lesions of testis showed significant difference(P<0.05).The optimum ADC to distinguish malignant testicular lesions from benign testicular lesions was 0.911×10 -3mm2/s(82.4% sensitivity and 82.4% specificity). Conclusion DWI combined with ADC value is beneficial to the preoperative diagnosis and differential diagnosis between malignant testicular lesions and benign lesions of testis.

Objective: To explore the correlation between pull-up ability and upper body composition of male college students in a college in Guangxi, and to provide scientific guidance for college students’ exercise. Methods: A total of 685 male college students were randomly selected from a college in Guangxi.Pull up tests were implemented according to the national physical health test standards. Measurements of muscle mass, fat mass, fat percentage, etc. of the upper limbs were conducted by using the Ogilvy Body Composition Meter (TANITA MC-180). Data entry and analysis were performed by using SPSS 23.0. Results: The pass rate of male college students in the region was 21.7%; There was a statistically significant difference in the fat mass and percentage of body fat between males with different pull-up ability (F=11.30，14.18，12.91，15.22，P<0.01).After controlling age, height, weight and BMI, partial correlation analysis showed that there was a negative correlation between the pull-up ability of male college students and the fat mass and limb fat rate of both upper limbs(r=-0.22, -0.33, -0.31, -0.38, P<0.01). Conclusion The ability of male students in Guangxi to pull up is needed to be improved. Pull-up exercises can reduce fat mass and fat percentage in the upper limbs and improve body composition.
