Objective: To observe the clinical effect of acupoint sticking therapy with Mian Tan Gao (facial paralysis paste) plus electroacupuncture (EA) for treating peripheral facial paralysis and its influence on patients' facial nerve functions, facial disability index and clinical symptoms and signs. Methods: A total of 96 peripheral facial paralysis patients were allocated into an observation group, a medicine group and an EA group by simple randomization, with 32 cases in each group. Patients in the medicine group were treated with oral mecobalamine and prednisone acetate; patients in the EA group were treated with EA on the basis of the medicine treatment; while patients in the observation group were treated with acupoint sticking therapy with Mian Tan Gao (facial paralysis paste) plus EA. After 4-week treatment, the clinical efficacy, the adverse events, and the scores of House-Brackmann (H-B) facial nerve function grading scale, visual analog scale (VAS), clinical symptoms and signs, and facial disability index (FDI) were compared. Results: After 4-week treatment, the total effective rate was 96.9％ in the observation group, higher than 68.7％ in the medicine group and 75.0％ in the EA group (both P<0.05). After 4-week treatment, the scores of H-B grading scale, VAS and clinical symptoms and signs in the three groups dropped significantly compared with those before treatment, and the scores in the observation group were lower than those in the medicine group and EA group (all P<0.05). After 4-week treatment, the facial disability index-physical function (FDIP) in the FDI in the three groups increased significantly, with a higher value in the observation group compared with that in the medicine group and EA group (both P<0.05). The facial disability index-social function (FDIS) in the FDI dropped significantly, with a lower score in the observation group compared with that in the medicine group and EA group (both P<0.05). However, the comparisons of the items above between the medicine group and the EA group showed no statistical significance (all P>0.05). The between-group comparison of the adverse event across the three groups showed no statistical significance (P>0.05). Conclusion: Acupoint sticking therapy with Mian Tan Gao (facial paralysis paste) plus EA can decrease H-B grade, reduce pain severity and improve clinical symptoms and signs as well as the facial disability condition in peripheral facial paralysis patients. This method produced more significant efficacy compared with oral medicine and medicine plus EA.

Objective To analyze the epidemic trend of hepatitis B virus (HBV) in 18 minority nationalities in Yunnan Province from 2009 to 2018, so as to explore the ethnic differences in the incidence of HBV in Yunnan Province. Methods Based on the reported incidence data of hepatitis B in China's disease prevention and control information system from 2009 to 2018, descriptive epidemiology method was used to describe and analyze the incidence of hepatitis B in different ethnic groups, and K-means clustering method was used to explore and analyze the annual average incidence of hepatitis B in different ethnic groups. Results From 2009 to 2018, the average incidence of hepatitis B in Yunnan Province was 44.26/100 000, which was much lower than the overall level of China every year; the average incidence of hepatitis B in ethnic groups was 41.27/100 000, slightly lower than the overall level of Yunnan every year. The prevalence of hepatitis B was different in different ethnic groups. The average incidence of Wa was significantly higher than others (95.26/100 000), and Jingpo was the lowest (22.51/100 000). According to the incidence of hepatitis B, different ethnic groups were divided into three categories: high incidence ethnic group, middle incidence ethnic group and low incidence ethnic group. Conclusion There are ethnic differences in the incidence of hepatitis B in Yunnan Province. The incidence of hepatitis B in some ethnic groups is higher than that in the whole country all the year round, which is the key population in the prevention and control of hepatitis B.

Objective To construct luciferase reporter plasmids of truncated fragments of different lengths of human guanylate binding protein 5(GBP5)gene promoter and analyze the transcriptional activity of each fragment to determine the core regulatory region.Methods GBP5promoter sequence was amplified by PCR,truncated into five fragments of different lengths and connected to pGL3-basic plasmid.The constructed recombinant plasmids pGL3-GBP5-11/21/31/41/51were transfected into 293FT cells and detected for luciferase activity.The binding sites of transcription factors in GBP5promoter region were predicted by JASPAR software,and Yin-Yang transcription factor 1(YY1)targeting the core regulatory region was selected and verified for the transcriptional regulatory activity.The CDS sequence of YY1 was amplified by PCR to construct the overexpression plasmid pIRES2-EGFP-YY1,which was then co-transfected to 293FT cells with plasmids pGL3-GBP5-21(-1 623 ～ +47 bp)and internal reference plasmid pRL-CMV,and detected for luciferase activity to analyze the regulation of transcription factor YY1 on GBP5 promoter activity.Results Colony PCR and double enzyme digestion identification proved that the plasmid of human GBP5 promoter reporter gene was correctly constructed;JASPAR software predicted that there were multiple transcription factor binding sites such as STAT1,YY1 and Foxp3 in GBP5promoter region.Double luciferase activity assay showed that pGL3-GBP5-21(-1 623 ～ +47 bp)showed the highest promoter activity,while the promoter activity of pGL3-GBP5-41(-520 ～ +47 bp)decreased significantly,suggesting that the core region of GBP5 promoter was located at upstream-1 623 ～-520 bp of 5 'UTR;Overexpression of YY1 significantly activated the GBP5 promoter activity and regulated the expression of GBP5.Conclusion The core regulatory region of human GBP5 promoter was located in upstream-1 623 ～-520 bp of the 5 'UTR,with a binding site of transcription factor YY1 existing in this region.Meanwhile,overexpression of YY1 significantly effected the activity of GBP5 promoter.

Congenital coronary sinus anomalies are extremely rare, and they have received relatively little attention. This is probably due to the lack of both clinical symptoms and significant cardiac functional disturbance. We present two cases of a coronary sinus anomaly and briefly review the literature. Recognizing and being familiar with the variations of a congenital coronary sinus anomaly in congenital heart disease may avoid a misinterpretation of cardiac catheterization findings and the troublesome disruption of coronary sinus blood return during the surgical management of cardiac lesions.

TGF-beta, as an inhibitor of hemopoiesis, excreted by hematopoietic stem and progenitor cells, down-regulates the expression of cytokines such as Flt-3 ligand, SCF, IL-3 etc on the stem and progenitor cells. The effect of anti-TGF-beta antibody on ex vivo expansion and expression of adhesive molecules on cord blood CD34(+) cells was studied in this research. The CD34(+) cells from six units of fresh umbilical cord blood were enriched by density gradient sedimentation and purified by miniMACS cell isolation system, and plated them into the SFEM serum free culture system which containing SCF, Flt-3L, TPO and IL-3 in the condition of 37 degrees C, 5% CO2, and saturated moisture. There were three groups in this experiment: (1) blank group: same as the culture system described above; (2) control group: added with normal rabbit IgG into the mentioned culture system; (3) test group: the same culture system with anti-TGF-beta1 antibo-dy. Cultured for 6 days, the number of mononuclear cells (MNC) was counted, the expression of CD34 antigen, CD117 (c-kit) antigen, CD11a antigen, CD49d antigen and CD33 antigen was tested with FCM. Meanwhile, cells of the three groups were plated in the methylcellulose culture system for 14 days, the number of CFU-GEMM, BFU-E, CFU-GM was counted. The results indicated that the expansion multiples of MNC, CD34(+) cells, CD34(+)c-kit(+) cells, CFU-GEMM in the test group (41.82 +/- 13.49, 15.62 +/- 6.95, 13.36 +/- 6.12, 11.07 +/- 4.05) were significantly higher than in the control group (28.86 +/- 9.03, 10.40 +/- 4.98, 9.04 +/- 4.40, 6.36 +/- 2.37) (P = 0.001, 0.002, 0.003, 0.002) respectively. The expansion multiple of more primitive CD34(+)c-kit(-) subpopulation in the test group (69.10 +/- 41.06) was even higher than in the control group (27.29 +/- 10.40) (P = 0.024). Adhesion molecule expression on the CD34(+) cells after short-term expansion: the expression of CD11a on the CD34(+) cells of the original cord blood was (61.73 +/- 4.13)%, and CD49d was (55.12 +/- 5.22)%. After expansion in each group the expression of CD11a on the CD34(+) cells did not change with statistical significance (P > 0.05), the expression of CD49d increased (P < 0.05). Compared with blank group and control group, anti-TGF-beta antibody did not impact on the expression of CD11a and CD49d (P > 0.05). It is concluded that anti-TGF-beta antibody can synergize other cytokines to effectively enhance the proliferation of cord blood NC, CD34(+) cells, progenitor subpopulation of CD34(+)c-kit(-) cells, and increase the output of more primitive progenitor colony, CFU-GEMM and BFU-E. At the same time, anti-TGF-beta antibody did not depresss the expression of adhesion molecules on CD34(+) cells.

OBJECTIVE: To analyze the relation between the clinical outcome and the integrity of the facets after a lumbar operation,and to provide a reference for choosing operative method and clinical prognosis. METHODS: Forty-three patients with complete data underwent uni-segment discectomy were enrolled. There were 3 surgical interventions: open-window discectomy, full or semi-laminectomy. Groups were divided based on the integrity of the facets after the operation, and the clinical symptoms and signs were evaluated using the Japanese Orthopaedic Association Back (JOA) scores at 24-month follow-up. RESULTS: Preoperative JOA scores were not significantly different among the groups (P>0.05). Compared with the facet intact group at 24-month follow-up,JOA scores were descended statistically in total uni-facetectomy group and total uni-facetectomy plus partial opposite facetectomy group (P<0.01). CONCLUSION Keeping facets integrated plays an important role in achieving good clinical results,and the damage of facet should be avoided in the lumbar operation.

Objective To explore the effect of family support service intervention on improving the rehabilitation of patients with severe mental disorders in community and the mental health status and family burden of family members. Methods Using multi-stage random sampling method, 100 patients who met the diagnostic criteria of severe mental disorders were randomly selected from two communities, and then 100 patients who met the diagnostic criteria of severe mental disorders were randomly matched according to gender, age and diagnosis in other communities into the control group. The control group and intervention group were set up strictly according to the inclusion criteria of patients and their families. Results The average age of the 200 groups was (48.27±12.67) years, and the average age of the family members was (63.61±13.19) years. After intervention, the activity dailyliving scale (ADL) scores of the control group were higher than those of the intervention group at all time points (all P<0.05). After intervention, the social disability screening schedule (SDSS) scores of the control group were higher than those of the intervention group at all time points (all P<0.05). After intervention, there was no significant difference in the morningside rehabilitation status scale (MRSS) score between the intervention group and the control group at all time points (all P>0.05). After intervention, the SCL-90(self-reporting inventory) scores of the mental health of the family members in the control group were higher than those in the intervention group at all times (all P<0.05). After intervention, the family burden scale of diseases (FBS) scores of the control group were higher than those of the intervention group at all time points (all P<0.05). Conclusions The intervention measures did improve the rehabilitation effect of severe mental disorder patients in community and the psychological and family burden of family members. A professional family support service team should be established.

OBJECTIVETo investigate the effect of two methods of pigmentation on the flexural strength of dental Y-TZP/porcelain layered structure.

METHODSKaVo zirconia substructures were pigmented by dipping presintered blocks in the coloring solution VITA LL1 and LL5, and colored TZ-3YS zirconia substructures were fabricated by adding pigments before isostatic pressing. The colors No.1 and No.5 were used for the test. The specimens were made in monolithic or bilayered forms, and the flexural strength was tested. XRD and SEM with EDX were used to analyze the characteristics of the surface structure.

RESULTSIn KaVo group, no significant differences were found in the flexural strength between white and LL1 and LL5 colored monoclinic materials, nor in bilayered structures. While in TZ-3YS group, significant differences were noted in the flexural strength between color No.5 white and color No.1 monoclinic materials, but not between the latter two subgroups. The flexural strength was significantly lowered by veneering with porcelain in both zirconia groups, and similar findings were observed with the monoclinic materials. Only the tetragonal phase was detected in both of the zirconia groups.

CONCLUSIONPigmentation has no apparent effects on the bonding strength between the veneering porcelain and zirconia. Both coloring methods are appropriate when the concentration of the pigments is under deliberate control.
