Objective:To provide a basis for the choicing of Semen Cuscuta baked with stir frying with yellow wine.Methods: The orthogonal design was adopted to optimize the processing methods. The content of total flavonoids determined was as a marker to evaluate the different processes. Other three comparative experiments with different auxiliary materials were observed. Results: the optimum processing method with yellow wine was A 2B 3C 1D 2, and the contents of total flavonoids of test sample was highest in the experiments.Conclusions: The optimum processing method with yellow wine is feasible.

Objective To compare the efficacy of Letrozol ( LE) regimen for ovulation induction in elderly and younger patients with polycystic ovary syndrome (PCOS).Methods A total of 67 ovulation induction cycle by LE regimen in patients elderly than 35 years old or younger than 28 years old with PCOS were studied .The endometrial thickness,morphology,number of dominant follicles,ovulation on the day of injection HCG and pregnancy outcome were recorded.Results The endometrial thickness were significantly different between the two groups [(7.9 ±1.7) mm vs (9.4 ±3.2)mm,t=2.648,P<0.05],but the endometrial morphology of AB type ,the number of dominant follicles and ovulation,pregnancy rate were indifferent [71.9% vs 77.8%,(1.5 ±1.5) vs (1.4 ±1.2),(1.3 ± 0.8) vs (1.4 ±1.2),37.5%vs 27.8%,t=2.456,1.995,1.758,1.525,all P>0.05].Conclusion LE regimen for ovulation induction is effective for PCOS patients of all ages ,although the elderly patients with endometrial thick-ness is less than that in younger ones .The number of dominant follicles ,endometrial morphology and ovulation is no different,don′t reduce pregnancy rates .

OBJECTIVE:To evaluate the efficacy and adverse effects of paroxetine alone or in combination with small dose of doxepin for somatization disorder.METHODS:280 patients with somatization disorder were randomly assigned to receive paroxetine alone or in combination with small dose of doxepin for 8 weeks.Clinical global impression scale(CGI)and symptom check list(SCL-90)were used to assess the efficacy,and treatment emergent symptom scale(TESS)was used to assess the adverse effects.RESULTS:After treatment for 8 weeks,CGI score showed the total effective rate was 87.5% in the patients treated with paroxetine alone versus 93.8% in those treated with paroxetine in combination with small dose of doxepin(P0.05).CONCLUSION:Paroxetine in combination with small dose doxepin showed better efficacy for somatization disorder yet without increasing adverse effects as compared with paroxetine alone.

BACKGROUND:Occlusal stimulation is essential for mandible function and remodeling, but there is stil a lack of clear understanding about the effect of occlusal stimulation on the bone remodeling in the process of bone defect repair using bone grafts. OBJECTIVE:To analyze the possible regulative effect of occlusal stimulation on bone remodeling in the process of bone defect repair using colagen substitutes. METHODS:Standard models of bone defects were respectively established in left mandible and parietal bone area of adult Sprague-Dawley rats. Then the bone defects area were filed with colagen and bone meal. The differences of two bone defects areas were observed by X-ray, hematoxylin-eosin staining, Gomori staining, tartrate-resistant acid phosphatase staining and bone morphogenetic protein 2 immunohistochemical staining at the 12th week after operation. RESULTS AND CONCLUSION: New bone formation was visible in the bone defect regions of the mandible and parietal bone. The amount of lamelar bone formation and the degree of mineralization of the new bone were significantly increased in the parietal bone defect compared with the mandibular bone defect area, indicating the bone remodeling in the parietal bone defect area was better than that in the mandible bone defect area. The integral absorbance values of tartrate-resistant acid phosphatase and bone morphogenetic protein 2 in the parietal bone defect area were lower than those in the mandibular bone defect area, indicating that the viabilities of osteoblasts and osteoclasts in the parietal bone defect area were lower than those in the mandible bone defect area. These results demonstrate that occlusal stimulation may delay the bone remodeling during the repair of mandibular bone defects by regulating bone mineralization and maturation.

BACKGROUND: There is a close relationship between innervations and bone formation and bone mass maintenance in the extraction sockets. OBJECTIVE:To study the possible effect of denervations on the regulation of new bone formation and bone mass maintenance in the extraction sockets. METHODS:The unilateral inferior nerve of dogs was sectioned to establish an animal denervation model. The normal side was used as control. After model establishment, the premolars of denervated side and normal side were extracted. Histological method was used to test new bone formation and bone mass maintenance in the extraction sockets at the 2nd, 4th, 8th and 12th weeks after tooth extraction. RESULTS AND CONCLUSION:The percentage of new bone areas in the extraction sockets was significantly lower in the experiment group than the control group at weeks 2, 4, 8 after tooth extraction (P < 0.01). The height difference between the buccal and lingual alveolar ridge was higher in the experimental group than the control group at weeks 2, 4, 8, 12 after tooth extraction (P < 0.05 or P < 0.01). These findings indicate that denervation is closely related with new bone formation and bone mass maintenance in the extraction sockets.

Objective:To compare the outcomes of combined lingual mucosal graft with buccal mucosal graft urethroplasty and combined lingual mucosal graft with ADM (acellular dermal matrix) urethroplasty for the treatment of repair failed hypospadias.Methods:From February 2017 to February 2019, 26 patients with failed hypospadias repairs were treated with combined lingual mucosal graft with buccal mucosal graft urethroplasty (14 cases in Group A), and combined lingual mucosal graft with ADM urethroplasty (12 cases in Group B). The mean age of Group A was (29.5±1.2) years (range 18.0-41.0 years), and (26.5±0.8) years (range 20.0-38.0 years) in Group B. The previous operation times was mean (3.6±0.7)(range 2-5 times) and (4.6±0.8)(range 3-5 times) in Group A and Group B respectively. Operation method: All patients were nasally intubated, the remaining curvature was corrected, the fibrous tissue or scar was removed, and the defected urethra was measured. In Group A, the lingual mucosa was spread and fixed to the corpora cavernosa over the midline as the urethral plate, the buccal mucosa was covered the lingual mucosa as ventral urethra, both the mucosa lateral edges was sutured. In Group B, the lingual mucosa was harvested and fixed to the corpora cavernosa the same as in Group A, the ADM was made appropriate length and width, covered and sutured with the lingual mucosa. The lingual mucosa was harvested mean (5.0±0.2)cm(range 4-6cm)long, mean (1.2±0.2)cm (range 1.0-1.5cm)wide and mean (5.0±0.2)cm(range 5-6cm)long, mean (1.2±0.2)cm (range 1.0-1.5cm)wide in Group A and Group B respectively( P<0.05). In Group A, the buccal mucosa was harvested mean (4.1±0.2)cm(range 3.5-5.5cm)long, mean (1.2±0.2)cm wide. Criteria for successful repair of hypospadias were set as: ①The appearance of the penis is nearly normal; ②The penis curvature was corrected; ③Urethra orifice in normal position; ④Urine flow line is normal. The outcomes of the two groups were analyzed and compared, statistical analysis was done using SPSS 18.0 software. Results:The mean follow-up time was (16.3±1.6)(8-24) months. The age, number of preoperative surgeries, number of previous oral mucous membranes, and length of urethral defects were no statistically significant differences between the two groups in A and B( P>0.05). The length of oral mucosa was harvested during the operation between group A and Group B were statistically significant differences( P<0.05). The incidence of oral complications in group A and B: Oral pain 7/14, 1/12; The feeling of tension in mouth 8/14, 1/12; The numbness in the oral 8/14, 1/12, A and Group B were statistically significant differences( P<0.05). The incidence of urethral complications in group A and Group B: the urethra fistula 1/14, 4/12; the urethral stricture 2/14, 6/12, there were statistically significant differences between the two groups ( P<0.05). Penile curvature 2/14, 1/12, ( P>0.05). The success rate was 12/14 and 5/12 in Group A and B respectively, with statistical difference( P<0.05). Conclusions:Combined lingual mucosal graft with buccal mucosal graft urethroplasty could be a good choice for repeated failed hypospadias repairs. Combined lingual mucosal graft with ADM urethroplasty has many complications and less success, should be performed in caution.
