Objective: To observe the clinical efficacy of needling nape acupoints in the treatment of pseudobulbar palsy. Methods: One hundred and twenty cases of pseudobulbar palsy were randomized into two groups, a treatment group in which 60 cases were treated by needling nape acupoints and a control group in which 60 cases were treated by needling tongue acupoints; after one-month treatment, the clinical symptoms and signs were observed. Results:The cure rate and total effective rate were respectively 41.7% and 90.0% in the treatment group,and respectively 26.7% and 81.7% in the control group, with differences in the cure rate and total effective rate between the two groups (P＜0.01). Conclusion: Needling nape acupoints is quite effective to treat pseudobulbar palsy in the relief of clinical symptoms and signs.

Objective To analyse the effects of serum estradiol levels during controlled ovarian hyperstimulation (COH) on the outcomes of in vitro fertilization and embryo transfer (IVF-ET). Methods The clinical data of 472 patients undergoing IVF-ET with GnRH analogues recombinant FSH long protocol were retrospectively analysed. The area under the curve (AUC) of estradiol (E2) level was calculated during COH, and patients were categorized into groups according to the percentile of AUC of E2(AUCE2) during COH. The general characteristics and parameters related to the outcomes of IVF-ET were compared among groups. Results The 10th percentile and 90th percentile of AUCE2 were 3 347.0 pmoL/L and 14 414.3 pmol/L, respectively. Four hundred and seventy-two patients were divided into lower reaction group (AUCE2 3 347.0 pmol/L, n=48), normal reaction group (14 414.3 pmol/L>AUCE2 > 3 347.0 pmol/L, n=376) and higher reaction group (AUCE2≥14 413.3 pmol/L, n=48). There was no significant difference in age, body mass index, baseline follicle stimulating hormone level, time of treatment with gonadotropin, endometrium thickness on day of transfer and embryos transferred(P>0.05). Compared with lower reaction group and normal reaction group, the number of oocytes per retrieval and number of embryos frozen were significantly larger(P<0.01) and the mild/severe ovarian hyperstimulation syndrome rate was significantly higher in higher reaction group(P<0.05). There was no significant difference in fertilization rate, cumulative embryo score, high-grade embryo rate, clinical pregnancy rate and implantation rate among groups (P> 0.05). Conclusion Sustained snpraphysiological serum E2 levels during the COH process do not adversely affect the quality of oocytes and embryos, clinical pregnancy rate and implantation rate to some extent in IVF-ET.

BACKGROUND:Previous studies have found that platelet-rich fibrin has a good ability to induce gingival soft tissue repair and regeneration.
OBJECTIVE:To observe the effects of platelet-rich fibrinversus colagen membrane on gingival soft tissue healing, and to evaluate the ability of platelet-rich fibrin to repair gingival defects.
METHODS:Twenty-two patients (2 premolar teeth and 20 molars) scheduled for premolar or molar removal or ridge preservation due to various reasons were selected and randomized into two groups. Bio-Oss was implanted into the extraction socket folowed by covering with platelet-rich fibrin or colagen membrane. Healing time and healing rate of gingival defects were detected to evaluate the ability of platelet-rich fibrin to promote gingival tissue healing at 1-2 weeks after Bio-Oss implantation.
RESULTS AND CONCLUSION:The healing time was (12.17±2.25) days in the platelet-rich fibrin group and (17.30±2.58) days in the colagen group. The healing rate of the platelet-rich fibrin group was notably higher than that in the colagen membrane group at 1 and 2 weeks after Bio-Oss implantation. These findings indicate that platelet-rich fibrin is better than colagen membrane to improve the healing of gingival soft tissues with a shorter healing time.

BACKGROUND: In clinical, the research on the method and the material of the soft tissue defect of the operation area has been in depth. It wil have a positive impact on our exploration and research in this field through the establishment of reliable experimental animal oral soft tissue defect model. OBJECTIVE: To establish a rabbit model of oral soft tissue defects for oral treatment of soft tissue defects in-depth study. METHODS: Eighteen 3-month-old male New Zealand rabbits were enrol ed. A tissue ring cutting dril of 5 mm diameter was used to prepare round ful -thickness soft tissue defects in the front part of the hard palate and, respectively, from the back of the maxil ary incisors, about 2 mm from the hard palate mucosal edge. Morphology and histology were observed at 3, 7, 14, 21, 28 and 56 days after model establishment. RESULTS AND CONCLUSION: (1) Morphological observation: After 3 and 7 days, the wound’s inflammatory reaction was obvious. As the time goes, the inflammatory response subsided, the wound gradual y healed. Scar formation was observed at 21, 28 and 56 days after surgery. (2) Histological observation: 3 and 7 days after injury, many inflammatory cel s were infiltrating, and tissue necrosis area was larger. At 7 days after surgery, with the extensive formation of connective tissue proliferation and new blood capil aries, the wound gradual y shaping completely. (3) Results indicated that a rabbit model of oral soft tissue defects was successful y established, which was in line with the physical laws of wound healing and the characteristics of human oral soft tissue defects healing.

Objective To evaluate the therapeutic efficacy of neoadjuvant chemotherapy in cervical carcinoma. Methods TAC(DDP, EPI and BLM) was applied in 68 patients with cervical carcinoma. Therapeutic efficacy and side effects were documented. Results After 1～3 cycles of neoadjuvant chemotherapy, clinical symptoms remission rares reached 100% ,response rate were 100% (40/40) in Ⅰ b～Ⅱ a,90.9% (20/22) in Ⅱ b and 50% (2/4)in Ⅲ a, respectively. Radical resection reached 91.2 %, and only 6 patients of advanced disease failed to radical resection and turned to radiotherapy. Conclusion Neoadjuvant chemotherapy is a safe and effective therapeutic option which could alleviate clinical symptoms, decrease tumor size, down-staging and increase the radical resection rate.

Objective To explore the prevalence of ETS gene fusion in prostate cancer and its correlation with patient's clinicopathologic index.Methods Ninety-one samples from prostate needle biopsy cases with median age 75 (55-90) years and 18 samples from radical prostatectomy cases with median age 72 (63-81) years were collected from Oct.2010 to Feb.2012.TMPRSS2-ERG,TMPRSS2-ETV1 and TMPRSS2-ETV4 fusions were tested by multi-probe fluorescence in situ hybridization (FISH) assay.Fusion positive and negative cases were compared with age,TNM stage,Gleason score (median Gleason score 7 (6-9)),and PSA value (median PSA 33.4 μg/L,mcan PSA 118.8 μg/L).In needle biopsy cases,there were early stage 32 (34％),locally advanced prostate cancer 36 (40％),metastasis 23 (26％) ; in radical prostatectomy cases,there were 9 cases in T2 stage,8 cases in T3 stage,1 cases in T4a stage,respectively.Results TMPRSS2-ERG fusions were present in 14.3％ (13/91,95％ confidence interval,0.071-0.215)biopsy specimens and in 11.1％ (2/18,95％ confidence interval,0-0.256) radical prostatectomy specimens.No TMPRSS2-ETV1 or TMPRSS2-ETV4 fusions were found in any cases.Altogether,13 (86.7％)cases possessed deletion pattern.And 7 (46.6％) hold insertion pattern.5 cases had both deletion and insertion pattern.38.5％ (5/13) deletion pattern had distant metastasis.Except one metastatic case harbored both deletion and insertion pattern,there was no insertion pattern accompanied with metastasis.There were no differences between fusion positive and negative cases in the distribution of age (P =1.000),PSA (P =1.138),primary Gleason score (P=2.186),Gleason score (P=2.107),TNM stage (P=2.052) and Risk Degree (P=2.597).Conclusions The TMPRSS2-ERG fusion positive cases harbor more deletion pattern than insertion pattern.There are no differences between fusion positive and negative cases in the distribution of age,PSA,Gleason score,TNM stage and Risk Degree.

Aim To study clinical efficacy of valsartan,in comparison with amlodipine, in hypertentive patients with left ventricular hypertrophy. Methods 65 hypertentive patients with left ventricular hypertrophy is divided into two groups, with 33 cases in valsartan group and 32 cases in amlodipine group Valsartan 80～160mg and amlodipine 5～ 10 mg were taken by the patients in the two groups for 6 months respectively. 24 h ambulatory blood pressure monitoring ( 24 h ABPM) and color echocardiography were performed in the two groups before and after treatment. Results The parameters of 24 h ABPM ( 24 h SBP? 24 h DBP?dSBP?dDBP?nSBP?nDBP) and color echocardiography (IVST?PWT?LVMI)after treatment in the two groups were significant decreased compared with those before treatment respectively (P0.05). Conclusion Valsartan can lower significantly the blood pressure level and make left ventricular hypertrophy remarkably dispelled in hypertensive patients with left ventricular hypertrophy and has the effect similar to that of amlodipine.

Objective To investigate the effect of chymase on the proliferation of rat cardiac fibroblasts (CFs) and the role of transforming growth factor-?1 (TGF-?_1).Methods Cultured CFs of neonatal SD rats were isolated by trypsinization.Cell number and DNA synthesis were evaluated by MTT assay (A_(490) value) and [~3H]-deoxythy- midine [~3H]-TdR incorporation.The mRNA expression of TGF-?_1 in CFs was determined by RT-PCR.Results Chymase increased CFs numbers and [~3H]-TdR incorporation in a dose-dependent manner.The A_(490) value of CFs stimulated by 15,30 and 60 ng/mL chymase was 0.263?0.033,0.348?0.031 and 0.387?0.026,respectively, which were all significantly higher than that of control (0.201?0.019,P
