OBJECTIVE: To observe the effect of acupuncture at Jiaji (EX-B2) points on upper limb motor dysfunction in patients after stroke. METHODS: A total of 62 patients with upper limb motor dysfunction after stroke were randomly assigned to an observation group (n=31, 3 cases dropped out) and a control group (n=31, 2 cases dropped out). Both groups received routine medical treatment and rehabilitation training. The control group was treated with conventional acupuncture at the affected side's Jianyu (LI15), Quchi (LI11), Shousanli (LI10), Huantiao (GB30), Yanglingquan (GB34), and Zusanli (ST36) etc. On this basis, the observation group received additional acupuncture at the affected side's Jiaji points from C₄ to T₅. Treatment was administered once daily, five times a week, for four weeks. Motor evoked potential (MEP) latency and amplitude of the abductor pollicis brevis and abductor digiti minimi, Fugl-Meyer assessment for upper extremity (FMA-UE), and Wolf motor function test (WMFT) scores were compared before and after treatment in the two groups. RESULTS: After treatment, both groups showed increased MEP amplitudes and decreased latencies of the abductor pollicis brevis and abductor digiti minimi (P<0.05), as well as increased FMA-UE and WMFT scores (P<0.05); the observation group had greater MEP amplitudes, shorter latencies, and higher FMA-UE and WMFT scores compared to the control group (P<0.05). CONCLUSION Acupuncture at Jiaji (EX-B2) points could enhance the excitability of upper limb motor neural pathways in upper limb motor dysfunction after stroke patients, thereby promoting motor function recovery of the upper limb.

Objective:To understand the employment psychology of college students in traditional Chinese medicine universities through analyzing relevant influencing factors, and to provide solutions to improve employment quality of the medical students.Methods:An online questionnaire survey on employment psychology and employment situation was conducted from August to September in 2017 among 384 students who had graduated from Longhua Hospital of Shanghai University of Traditional Chinese Medicine from 2013 to 2017. SPSS 19.0 was used for chi-square test and linear trend test on the survey results.Results:A total of 374 valid questionnaires were recovered, with the effective recovery rate of 97.4%. The results showed that the most important factors to be considered were professional counterparts (77.01%, 288 students), salary (75.67%, 283 students) and development prospect (69.52%, 260 students) and the most important psychological characteristics were hesitation and contradiction (50.8%, 190 students) and anxiety (25.13%, 94 students). The study found that employment psychology was related to students' family situation, category, temperament and performance during their education period.Conclusion:Students have different employment psychology, which can be improved by consummating career planning, broadening employment channels, combing employment policies, supplementing professional shortcomings, and improving comprehensive skills. Meanwhile, colleges and universities can expand their practice bases, provide employment counseling, and improve education resources, speed up the construction of the second classroom, pay attention to special groups to conduct employment guidance and improve the quality of employment.

Objective To discuss the difference of handwriting characteristics of schizophrenia,neurosis and healthy people according to the gender,the age and the level of educated.Methods The handwriting data were obtained under the standard condition of handwriting,then the 24 Chinese characters handwriting image information were transformed into digital data using the quantitative characteristics of Chinese characters handwriting recognition system (CCQAS4.0),finally the data of 99 patients with schizophrenia and 131 patients with neurosis were analyzed.Results Many significant differences had been found in schizophrenia,neurosis and norm group (P ＜0.05,P＜0.01),such as footer space((198.33±26.50) mm,(180.31±39.31)mm,(192.39±35.08) mm),average line spacing ((4.02 ± 1.68) mm,(5.34 ± 2.20) mm,(4.76 ± 2.00) mm) etc ; and there were also some important differences between the schizophrenia patient and the neurosis patient from different gender,age and education level in the 24 handwriting characteristics (P＜0.05,P＜0.01).Conclusions (1) Significant handwriting characteristic differences have surely been found among the schizophrenia/neurosis patient and normal people.(2) Gender,age and education level have impact on the characteristic in the schizophrenia patient and the neurosis patient.

The immune effect of two recombinant protein fragments of spike protein in severe acute respiratory syndrome coronavirus (SARS CoV) was investigated in Balb/c mice. Two partial spike gene fragments S1 (322-1464 bp) and S2 (2170-2814 bp) of SARS coronavirus were amplified by RT-PCR, and cloned into pET-23a prokaryotic expression vector, then transformed into competent Escherichia E.coli BL21 (DE3)(pLysS) respectively. Recombinant proteins were expressed and purified by Ni2+ immobilized metal ion affinity chromatography. The purified proteins mixed with complete Freund adjuvant were injected into Balb/c mice three times at a two-week interval. High titer antibody was detected in the serum of immunized Balb/c mice, and mice immunized with S1 protein produced high titer IgG1, IgG2a, IgG2b and IgG3, while those immunized with S2 protein produced high titer IgG1, IgG2a, but lower titer IgG2b and IgG3. Serum IFN-γ concentration was increased significantly but the concentrations of IL-2, IL-4 and IL-10 had no significant change. And a marked increase was observed in the number of spleen CD8+ T cells. The results showed that recombinant proteins of SARS coronavirns spike protein induced hormonal and cellular immune response in Balb/c mice.

Objective:To investigate the syndromes distribution in patients with dysfunctional uterine bleeding(DUB) related to kidney deficiency, and to provide the basis for standardizing the DUB syndrome differentiation of kidney deficiency. Methods: DUB Patients with kidney deficiency were chosen and accepted epidemical survey through the questionnaire, then the frequency and constituent ratio of each syndrome were calculated. Results: In 612 cases of DUB patients with kidney deficiency, there were 102 patients with simple syndromes covered 16.67%, and 510 patients with compound syndromes covered 83.33%. In patients with simple syndromes, the common syndromes were kidney-yin deficiency(45,44.12%) and kidney-qi deficiency(45,41.18%). And the syndromes of kidney-qi deficiency and kidney-yin deficiency were often respctively complicated with liver stagnation(68,11.09%; 113,18.43%), blood defi ciency(57,9.30%; 99,16.15%) and blood stasis(57,9.30%; 99,16.15%), the syndrome of kidney-yang deficiency usually complicated with spleen-qi deficiency(75,12.23%). The syndrome of kidney-qi deficiency(186,57.23%) was commonly-seen in the patients with ovular DUB, while the syndromes of kidney-qi(146,50.69%) and kidney-yin deficiency(111,38.54%) were frequently-seen in the patients with anovular DUB. Conclusion: In clinic, the compound syndromes were commonly seen in patients with DUB due to kidney deficiency, the complicated syndromes of kidney deficiency were liver stagnation, spleen-qi deficiency, blood deficiency and blood stasis..

To construct a recombinant plasmid Pet23a-M, the gene encoding severe acute respiratory syndrome (SARS) coronavirus membrane protein was amplified by RT-PCR and cloned into the expression plasmid Pet23a. Results of restriction endonuclease analysis, PCR detection and DNA sequencing analysis revealed that the cloned DNA sequence was the same as that reported. The recombinants were transformed into Escherichia coli (E. Coli) BL21 (DE3) and induced by Isopropyl-beta-D-thiogalactopyranoside (IPTG). The expression of 27 kD (1 kD=0.992 1 ku) protein was detected by SDS-PAGE and pured by metal chelated chromatography. Results of Western-blot showed that this expressed protein could react with antibodies in sera of SARS patients during convalescence. This provided the basis for the further study on SARS virus vaccine and diagnostic agents.
