Compound traditional Chinese medicine database was established by collecting 176 compound formulas for dysmenorrhea in the last twenty years. The proportion and frequency of herbal medicine were analyzed and the main herbs with mono-target or multi-target in the compound formulas were selected with simple and multiple linear regression. The linear regression equations were listed and the clinical effects of the compound formulas were evaluated. Of 173 herbs used in the compound formulas, the proportion and frequency of the herbs for activating blood and transforming stasis and regulating qi flow were high in the application. The dosage interval for 20 herbs in common use was estimated. Main herbs with mono-target or multi-target used in the compound formulas were selected with simple and multiple linear regression. The total effectiveness rate of the 176 compound formulas was tested with simple linear regression, and 167 compound formulas (94.84 % of the total) had the absolute error less than 4%. Herbs for activating blood and transforming stasis and regulating qi flow are most commonly used in treatment of dysmenorrhea. Clinical effects of the compound formulas could be forecast with stepwise regression equation.

Serial sections of the tongues of rabbits, albino rats, pigs, dogs, frogs, toads andhuman beings have been made to study the motor nerve endings by the silver imprega-tion method of Cajal Faworsky. The end-plates of the muscle of their tongues has its own specific characteristic, thefunctional significance of these motor nerve endings of the muscle of tongues has beendiscussed. In our investigation we have found out three kinds of unusual motor nerve endings:(1) A single motor end plate, located at two adjacent muscle fibers, has a small branchwhich runs to another muscle. (2) An accessory ending, formed by different startingpoints of nerve fiber, has been found in dogs. (3) Triple motor inervation of individualmuscle fiber of the tongues is to be found in human beings.

Objective To learn the effect of breast removal of polyacrylamide hydrogel by areola incision;and to provide an effective method for removal of polyacrylamide hydrogel.Methods According to the accepted operation,45 cases with breast polyacrylamide hydrogel were divided into 25 cases of observation group and 20 cases of control group.The observation group was treated with areola medial semicircular incision breast removal of polyac-rylamide hydrogel,and the control group was treated with areola small incision suction to remove polyacrylamide hydrogel.The operative time,intraoperative blood loss,postoperative drainage tube extraction time,postoperative 7d breast shape and perioperative complications of the two groups were observed;postoperative follow -up was performed to evaluate the effect of surgery.Results The operation time of the observation group (190.2 ±36.1)min was longer than (119.5 ±44.0)min of the control group,the difference was statistically significant between the two groups (t =5.924,P <0.05);the intraoperative blood loss of the observation group (250.4 ±23.9)mL was higher than (89.7 ± 30.4)mL of the control group,the difference was statistically significant (t =19.865,P <0.05 ).The difference between postoperative 7d breast normal morphology rates of the two groups was not statistically significant (χ2 =2.571,P >0.05);the postoperative drainage tube extraction time of the observation group (3.7 ±0.5)d was more than (2.3 ±0.3)d of the control group,the difference was statistically significant (t =11.021,P <0.05 ).The complication rate of the observation group was 12.0%(3 /25),which of the control group was 10.0%(2 /20),the difference was not statistically significant (χ2 =0.045,P >0.05).All cases of the two groups were followed up;the mean follow -up time was (6.7 ±2.1)months.The good rate of surgery of the observation group was 92.0 % (23 /25),which of the control group was 70.0%(14 /20),the observation group was higher than the control group (χ2 =5.718,P <0.05).Conclusion For patients with complications after polyacrylamide hydrogel injection for augmentation mammoplasty;the breast polyacrylamide hydrogel removal surgery by areola medial semicircular incision is recommen-ded as the preferred.

Objective To investigate the expression of hypoxia inducible factor-1α(HIF-1α) and vascular endothelial growth factor C(VEGF-C) in colon carcinoma,and their relation with clinical pathological parameters and prognosis. Methods Immunohistochemistry was used to detect the expression of HIF-1α and VEGF-C in 65 tissues of colon carcinoma. Results In all cases,the expression of HIF-1α had a positive correlation with the expression of VEGF-C(r= 0.638,P＜0.01).The expressions of HIF-1α and VEGF-C had significant correlation with clinical stage and nodal metastasis(P＜0.05) ,but had no relationship with sex,age and tumor size(P＞0.05). Conclusion The expression of HIF-1α and VEGF-C was correlated with nodal metastasis, tumorigenesis and prognosis of colon/carcinoma.

Aim To investigate the influence of Ramu-lus mori polysaccharides ( RMP) on blood glucose and anti-oxidative effect in streptozotocin ( STZ )-induced diabetic mice .Methods Diabetic mice were induced by intraperitoneal injection with 120 mg? kg -1 STZ and were randomly divided into the following 5 groups with 20 animals per group: model group , valsartan group ( 20 mg? kg -1 ) , low-, medium-, high-dose (0.3,0.6,1.2 g? kg -1 ) of RMP groups.Other 20 normal mice were treated as normal control group .The mice were administered orally for 90 d.On 45 d of ad-ministration , the 24 h urine was collected through met-abolic cages for urine protein detection .Pathological changes of kidney tissues were observed through HE staining .The serum levels of urea nitrogen ( BUN) and creatinine ( Cr ) were detected by automatic biochemical analyzer; and the manganese superoxide dismutase (Mn-SOD), catalase(CAT), malonaldehyde(MDA) and mitochondrial respiratory chain complex Ⅰ,Ⅲac-tivity of kidney tissues were also determined .ELISA method was used to detect ROS content in renal cortex . The SIRT1 , FOXO1 and NF-κB protein expressions were analyzed by Western blot .Results Compared with model group, the FBG, microalbuminuria, BUN and Cr were decreased by RMP medication ( P <0.05).The activities of Mn-SOD, CAT and mitochon-drial respiratory chain complex Ⅰ,Ⅲ in RMP groups were enhanced , while MDA and ROS levels were re-duced. Moreover, the expressions of SIRT1 and FOXO1 were up-regulated by RMP , the expression of NF-κB was down-regulated ( P<0.05) .Conclusion RMP exerts renal protective effect through up-regula-ting the expressions of SIRT1 and FOXO1 in renal cor-tex , which may relate to the improvement of anti-oxida-tive capability .

Objective To compare the outcomes of traumatic flail chest with multiple injuries treated by operative fixation versus conservative approach. Methods The clinical data of 60 patients with traumatic flail chest with multiple injuries were retrospectively analysed, and the outcomes between operation group (treated by operative fixation, n=32)and non-operation group (treated by conservative approach, n=28) were compared. Results The mean time of hospital stay, ICU stay and mechanical ventilation was significantly shorter, and the prevalences of chest wall deformity, pulmonary infection, pulmonary atelectasis and respiratory failure were significantly lower in operation group than those in non-operation group (P<0.05). Six months after discharge, the pulmonary function parameters such as inspiratory capacity, forced vital capacity, forced expiratory volume in one second, peak expiratory flow, total lung capacity and maximal midexpiratory flow were significantly higher in operation group than those in non-operation group (P<0.05). Conclusion Traumatic flail chest with multiple injuries treated by operative fixation may lead to less flail chest associated complications. Operative fixation has short- and long-term benefits to flail chest.

Objective To clarify the protective effect of nrsodeoxycholic acid ( UDCA ) on endoplasmic reticulum stress-mediated apoptosis in pancreatic β-cell of streptozotocin ( STZ )-induced diabetic rats.Methods Rats( n =40) received a single injection STZ( 50 mg/kg) intra-peritoneally and formed a β-cell injury model.Weight-matched normal rats( the control group,n =10 ) were injected with the buffer alone.STZ-treated rats with persistent random blood glucose higher than 16.7 mmol/L for 1 week were considered as diabetic status( n=14 ),then divided randomly into STZ-induced diabetes mellitus ( DM ) group ( n =7 ) and UDCA-treated DM group ( n =7 ).UDCA (40 mg· kg- 1,d-1 ) was administered daily by intragastric intubations throughout the experimental period (30 d).During the entire experiment,blood glucose in all rats was assessed.By the end of the experiment,all rats were sacrificed with the pancreas removed and the blood sample collected immediately.Fasting insulin levels were assayed by radioimmunoassay.The morphological changes of pancreatic β-cells apoptosis were determined by TUNEL assay.RNA in pancreas was abstracted and microarray containing 89 pieces of apoptosis related genes was applied.The related gene expressions were detected by RT-PCR and Western blot.Results The concentration of blood glucose in diabetic rats was gradually decreased after UDCA treatment,but at the end of the experiment it was still higher than that in the normal control group.The treatment with UDCA raised the fasting insulin level in diabetic rats,but this concentration was significantly lower as compared to the control group.Based on TUNEL stained tissue sections,the percentage of β-cell apoptosis of UDCA-treated DM group was significantly lower than that of STZ-induced diabetic group(P＜0.05 ).Among 89 genes,42 genes up-regulated and 46 genes down-regulated in diabetic rats,some of which were ameliorated by UDCA treatment.The expressions of Caspase-3,Bax,Bip,and CHOP mRNA in pancreas of DM group were significantly up-regulated as compared with those in the control group ( P ＜ 0.05 ) ; while the expression of Bcl-2 mRNA was markedly down-regulated (P＜0.05 ).However,these parameters in the U DCA-treated animals showed a marked improvement.Conclusion Ursodeoxycholic acid seems to protect pancreatic β-cell from apoptosis in STZ-induced diabetes by attenuating the severity of endoplasmic reticulum stress.
