BACKGROUND: It is thought in traditional Chinese medicine that "the head is the residence of intelligence", "the head is the leader of body, and the focus of the spirit". Therefore, scalp electro-acupuncture can induce resuscitation, relieve mental confusion, dredge the meridian and eliminate the depression in treatment of post-stroke depression.OBJECTIVE: To observe the curative effect of head acupuncture on poststroke depression.DESIGN: Randomized controlled and single blind evaluationSETTING: Department of Acupuncture and Moxibustion, Nanfang Hospital of Southern Medical University; College of Acupuncture and Massage,Guangzhou University of Traditional Chinese Medicine.PARTICIPANTS: Totally 90 patients with post-stroke depression were from Affiliated Nanfang Hospital and,Zhujiang Hospital of Southern Medical University, First Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine were recruited. The Score of all the patients in Hamilton Rating Scale for Depression (HRSD) were ＞ 20. Ninety patients were randomly divided as scalp acupuncture group (n=46) and routine acupuncture group (n=44).METHODS: The patients in the routine acupuncture group were treated mainly at points of three-yang meridians of foot and hand at the hemiplegia side. The points include jianyu (LI-15) , binao (LI-14) , quchi (LI-11),shousanli (LI-10), waiguan (SJ-5), hegu (LI-4), biguan (St-31), liangqiu (St-34), zusanli (St-36), yanglingquan (GB-34), kunlun (UB-60), jiexi (St41). The above points were divided into 2 groups, 1 group each day, alternately. Even reinforcing-reducing method was used, with 30-minute needle retention, 6 successive days treatment with 1 day rest, for 6 weeks totally.The patients in the scalp acupuncture were treated with, besides the above method, scalp acupuncture. Mid-parietal line, mid-frontal line, laterofrontal lineI (both sides)were chosen. After arrival of qi, G6805 type electro-acupuncture apparatus (interrupted wave, 50 Hz,4 V) was connected, with 30-minute needle retention, 6 suocessive days treatment with 1 day rest, 6 for 6 weeks totally. HRSD was used to evaluate the status of depression before and after treatment. Stroke score was used to evaluate the curative effect of stroke.MAIN OUTCOME MEASURES: HRSD scores and curative effect of apoplexy before and after treatment of the patients in two groups.RESULTS: According to the intention treatment, all 90 patients entered the result analysis. ① HRSD score after treatment was lower than that be fore treatment in the scalp acupuncture group,and that after treatment group in the routine acupuncture group (8.55±1.73,30.61±4.02,15.04±2.33,P ＜ 0.01 ). ②There was no significant difference of the total effective rate in the two groups , but some tendency indicated the effective rate in the scalp acupuncture group was better than that in the routine acupuncture group ( 100% ,98% ,x2=1.9167 ,P ＞ 0.05).CONCLUSION: Scalp electro-acupuncture has obvious curative effect on post-stroke depression. The amelioration of melancholia has a certain promoting effect on rehabilitation of apoplexy.

miRNA is a kind of endogenous non-coding short RNA. Mature miRNA was formed through the process of shearing and transporting after genetic transcription. miRNA exhibits many important biological functions through regulating expression and translation of target mRNAs. Different miRNAs may act as oncogenes or antioncogenes, and have tissue specificity. The progress of the tumorigenesis is usually accompanied by expression-profile changes of miRNAs. MiRNA regulates many tumor biological behaviors such as differentiation, proliferation, apoptosis, invasion, metastasis, and drug resistance of tumors. Furthermore, some miRNAs have clinical significance in predicting prognosis of tumor patients.

Objective To investigate the changes of T cells and disease development in the mice with Smad3 deficiency in the bone marrow cells.Methods Bone marrow cells obtained from Smad3 null(Smad3~(-/-))mice and wild type(Smad3~(+/+))mice were injected to Co~(60)-irradiated GFP mice,respectively.The general states of the bone marrow recipients were observed.The mice were sacrificed at the sixth week and the histopathological changes in the intestines were examined.The changes of T cells from lymph nodes were detected by flow cytometry.Results Smad3~(-/-) bone marrow recipient mice appeared a wasting syndrome and intestinal inflammation.The amount of CD4~+ CD62L~(lo) T cells in lymph nodes was significantly increased.Conclusion These results indicate that the mice with Smad3 deficiency in the bone marrow cells present an inflammatory disorder and their T cells are activated.

Objective To analyze the clinical and pathologieal characteristics of IgA nephmlogy secondary to primary sj(o)gren's syndrome(pSS).Method The clinical and pathological data of 8 patients with pSS and IgA in Changzheng Hospital from 2004 to 2009 were analyzed.Results The average age of seven female and one male was (44±8) years old.Five patients presented with edema and proteinuria.Eight patients presented with microhematuria.The average 24-hour proteinuria was (3±4) g.Two patients had hypertension.Serum creatinine levels of two patients were higher than normal level,the others'were normal.Light microscopy examination showed three patients were mild mesangial proliferation with Lee's classification grade Ⅰ;five patients had global sclerosis with Lee's classification grade Ⅱ,Ⅲ and Ⅳ.Positive IgA was mainly found under immunofluorescence microscopy.Electronic microscopy showed no electron-dense deposits.Conclusion IgA nephrology secondary to pSS is different from primary IgA nephrology under immunofluorescence microscopy.

BACKGROUND:It is suggested that glucose metabolism of frontal lobes,cingulate gyri and caudate nuclei in cerebral functional area of patients with depression is low,and the blood flow in cerebellum decreases.OBJECTIVE:To observe the effect of scalp acupuncture on cerebral glucose metabolism in depression by positron emission tomography.DESIGN:Randomly controlled and verifying experiment.SETTING:Department of Acupuncture and Aoxibustion in Nanfang Hospital and Center of Positron Emission Tomography in a Guangdong People's hospital.PARTICIPANTS:Twelve patients of primary depression,from Nanfang Hospital,Zhujiang Hospital and Center of Positron Emission Tomography in Guangdong People's Hospital from October 2002 to October 2003,were selected randomly with the diagnostic criteria of [F32] in the Third Edition of the Chinese Classification and Diagnostic Criteria of Mental Disease.Among them,3 were male and 9 were female.Their ages were from 36 to 66 years,with the average of 48.METHODS:Giving scalp acupuncture in middle line of vertex(MS5),middle line of forehead(MS1) and bilateral lateral line 1 of forehead(MS2).All the patients received positron emission tomography examination before and after acupuncture treatment for 6 weeks.Then cerebral Regions of Interest,bilateral frontal lobes,bilateral caudate nuclei,bilateral cingulate gyri and bilateral cerebella,were chosen and their average glucose metabolisms were counted by half-quantifying analysis.MAIN OUTCOME MEASURES:Glucose metabolism of bilateral frontal lobes,bilateral caudate nuclei,bilateral cingulate gyri and bilateral cerebella.RESULTS:According to intension,all 12 patients with primary depression sults of right frontal lobes(2.91 ±0.34),left frontal lobes(2.96±0.26),right cingulate gyri(2.68±0.20),right caudate nuclei (2.61±0.39) and left cerebellum(2.55±0.18)were obviously higher than those of right frontal lobes(2.53±0.31),left frontal lobes(2.53±0.36),right cingulate gyri(2.34±0.31),right caudate nuclei(2.40±0.33) and left cerebellum(2.35±0.25)before treatment(P＜ 0.05-0.01).However, the results of left cingulate gyri (2.69 ±0.38),left caudate nuclei(2.66±0.01) and right cerebellum(2.50±0.27) were similar to those of left cingulate gyri(2.43±0.38),left caudate nuclei(2.45±0.21) and right cerebellum(2.30±0.34) before treatment(P ＞ 0.05).CONCLUSION:Scalp acupuncture on middle line of vertex,middle line of forehead and bilateral lateral line 1 of forehead could improve the glucose metabolism in depressive patients of certain cerebral regions,and it might be a mechanism related to improvement of frontal lobes,caudate nuclei,cingulate gyri and cerebellum.

Objective:To investigate the expression of MMP-1 and PTEN protein in basal cell papilloma (BCP), as well as their correlation with skin photoaging. Methods:Immunohistochemistry technique via Elivison method was employed to measure the expres-sion of MMP-1 and PTEN protein in lesions from 50 cases of BCP on exposed areas, 50 cases on non-exposed areas, and 30 normal controls. We compared the differences among the three groups and analyzed the result. A total of 90 BCP cases on exposed areas were randomly divided into three groups. Titanium dioxide cream and placebo were respectively applied in the trial groups twice daily for 12 weeks, whereas the control group was non-administered. After 12 weeks, the MMP-1 in the lesions of the three groups was measured and compared. Results:The expression scores of MMP-1 on exposed areas were significantly higher than those in the control group (P<0.01). No significant difference was found between non-exposed areas and the control group (P>0.05). The expression scores of PTEN protein on exposed areas and on non-exposed areas were significantly lower than that in control group (P<0.01). The expression scores of MMP-1 in the group that used titanium dioxide were evidently lower than those in control group after 12 weeks (P<0.05). Conclu-sion:MMP-1 is overexpressed in BCP on exposed areas. PTEN protein is underexpressed in BCP of exposed areas and non-exposed ar-eas. Skin photoaging is a possible cause of BCP on exposed areas.

SCI-E and SSCI covered papers on psychiatry published from 2002 to 2011 by authors of China, USA and Japan were analyzed using bibliometrics and the number, relative impact power and international cooperation of these papers were compared among the 3 countries, which showed that both the number and impact power of SCI-E and SSCI covered papers on psychiatry published by authors of China increased, the number of papers published by authors of China was catching up with that published by authors of Japan, and the impact power of papers published by authors of China was higher than that published by authors of Japan.However, they were significantly lower than those published by authors of USA.It is quite important to publish papers in journals with a high academic level and to strengthen international cooperation for increasing the domestic scientific research level in psychiatry.
