Objective:To explore the personality types a nd the features of clinical subtypes of obsessive-compulsive disorder (OCD). Methods:82 cases of OCD were tested using Chinese MMPI that w as revised by MMPI normative cooperative group. We used MMPI-B auto-analysis sys tem made by Ji Shumao et al to calculate the basis scores and T scores of 73 sca les.Results:Basis scores (+K)of scales F,Hs,D,Hy,P d,Pa,Pt,Sc,(males and females)and Si,Mf(males) and K (females) on OCD group were higher that the scores of the normal group. The two-point code of T scores in O CD was 72/27.The factor analysis in 13 scales showed that there were fo ur personality factors in OCD: neuroticism factor (Hs,Hy,D,Pt), psychotic factor (F,Pd,Sc),suspicious factor( F,Ma,Pa), Social introvers ion factor (L,Si,Mf).82 cases of OCD were divided into three groups by K-means o f quick cluster analysis,T scores of 73 MMPI scale s were different among three groups (P<0.000).Conclusio n:The ps ychological features a nd comorbidity and responses to psychotherapy of three groups OCD are different.

OBJECTIVE:To investigate the method for rapid and effective isolating of calcium-tolerant cardiomyocytes(CTC) from rats. METHODS: CTC were obtained by retrograde perfusion using modified Langendorff heart perfusion apparatus. After incubation of cardiomyocytes in KB solution, the ion currents were recorded with patch-clamp technique in whole-cell mode. RESULTS: Of the whole isolated cells, 70% were survival. Of which, 80% were CTC. A typical outward potassium current was recorded. CONCLUSIONS: A large number of CTC with normal electrophysiological characteristics can be obtained by mastering the digestion time based on variation of perfusion pressure and keeping all the factors in cell isolation under control.

Objective To study the effects of the compound medicine of icariin and puerarin on peak bone mass in rats during growth period, and to explore its possible mechanism. Methods Forty female Sprague-Dawley rats aged 1 month were randomly divided into normal control group( C), icariin group( I), puerarin group( P), icariin and puerarin compound groupc(I+P), 10 in each group. The body weights were recorded once every two weeks, and the bone mineral density was measured by dual-energy X-ray absorptiometry every month. After the bone mineral density of the whole body was significantly different between the control group and drug groups the animals were sacrificed. The right femur and vertebrae were separated to measure the bone mineral density. The biomechanical properties of the femur and vertebra were detected by AG-IS series desktop electronic universal testing machine. The bone formation index osteocalcin, PINP and bone resorption index were determined by ELISA. Changes in the contents of tartrate-resistant acid phosphatase 5b(TRACP 5b) and CTX-1; and changes in trabecular bone related parameters were recorded after magenta-picric acid staining. Results There was no significant difference in body weight between the two groups (P＞0.05). There was no significant difference in whole body bone density after 1 month of treatment (P＞0.05). After 2 months of treatment, the body bone density of the drug-administered group was higher than that of the control group. Whole body bone density, femur and vertebral bone density, femur maximum load value, maximum vertebrae load value and trabecular bone number and area, serum OC and PINP levels increased, while TRACP 5b and CTX-1 levels decreased(P＜0.01) in drug group. The difference from the control group was statistically significant (P＜0. 05). There were significant differences in biochemical parameters and bone histomorphology between the compound drug group and the two-flavor monomer group ( P＜0. 01). There was no significant difference in bone mineral density and biomechanics, but the average value was higher than that of the monomer group. Conclusion The combination of icariin and puerarin can effectively increase the peak bone mass in rats.

Objective To study the relationship between the asthenia TCM syndromes in embryonic development stops and the level of zinc, iron, copper, magnesium, phosphorus, calcium in serum, and provide thoughts for assisting reproduction and preventing miscarriage. Methods Totally 100 patients of embryonic development stops were selected randomly (6-10 weeks gestation) to be the investigated group, with other 100 cases of live fetus as the control group. The contents of trace elements in serum were detected with atomic absorption spectrometry. Results The levels of trace elements in embryonic development stops patients were generally lower than the control group. The serum iron in patients with spleen deficiency syndrome, and serum zinc and iron in patients with kidney deficiency syndrome were significant lower (P<0.05). Conclusion The contents of trace elements in serum have relationships with asthenia TCM syndromes in embryonic development stops. It should be paid attention to supplementing trace elements during the gestation period. For patients with deficiency of kidney and spleen, the supplement of zinc and iron should be given greater prominence.

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.

Objective To explore the influence of Rosenthal effect on the psychological status of pregnant women at risk of miscarriage in early pregnancy. Methods From January 2014 to June 2015 151 cases of early pregnancy abortion risk women were set as the control group, and was given conventional psychological intervention.From July 2015 to December 2016 135 cases of early pregnancy abortion risk women were named as the observation group by convenient sampling selection, which was given interventionbased on Rosenthal effect on the basis of routine psychological intervention. The Self-rating Depression Scale (SDS) and the Self-rating Anxiety Scale (SAS) score, the introversion and extroversion scores and the satisfaction degree with intervention were compared between the two groups before and after the intervention. Results There was no significant difference in SDS and SAS scores, inotropic challenge and extroversion challenge between the two groups before treatment (P >0.05). The scores of SDS and SAS, the inotropic challenge and extroversion challenge scores were 41.45 ± 4.26, 40.34 ± 5.82,4.76 ± 1.03,5.55 ± 1.26 in the observation group after intervention,and 47.22 ± 3.93,47.18 ± 7.04,5.39 ± 1.12, 6.43 ± 1.86 respectively in the control group. There were significant difference in scores of SDS and SAS, the inotropic challenge and extroversion challenge (t=2.215-2.573, P <0.05). The satisfaction rates of the observation group and the control group were 93.32%(126/135)and 74.17% (112/151) respectively, the difference was statistically significant (χ2=5.921, P<0.05). Conclusions The intervention based on Rosenthal effect on the basis of conventional psychological intervention for early pregnancy abortion risk women can relieve negative emotions such as anxiety and depression, besides it can also improve satisfaction degree of inpatients with intervention.

A new type of multi-acupoints moxibustion instrument was developed to effectively solve the issue of simultaneously performing moxibustion at multiple acupoints. The moxibustion instrument consisted of a bracket and a moxibustion cartridge mounted on the bracket. The upper end of the bracket was equipped with gooseneck tubes. The free end of the gooseneck tubes was equipped with moxibustion cartridge used for moxibustion. The moxibustion cartridge consisted of the cartridge body, the moxa needle and the ash net. This current instrument with novel and unique structure was simple and reasonable, safe and reliable, and had the advantages of convenient operation, time and labor saving, and high moxibustion efficiency, and was an innovation of moxibustion instrument.
