Objective To investigate the surgical managements and effects of congenital islated penile curvature. Methods The degloving of penile shaft,penile dorsal tunical plication,urethral division and urethroplasty were performed in 23 patients with this entity including 2 cases of type Ⅰ,11 cases of type Ⅱ,6 cases of type Ⅲ,4 cases of type Ⅳ,mean age 7 years (age 1 to 21 years). Results Of all 23 patients 17 cases of type Ⅱ and Ⅲ were succesfully repaired by degloving of penile shaft;1 case of type Ⅰ,by degloving of penile shaft and dorsal tunical plication;1 case of type Ⅰ and 2 cases of type Ⅳ,by degloving of penile shaft,dorsal tunical plication and urethral division;2 case of type Ⅰ and Ⅳ,by urethroplasty.One case was complicated with urethrocutaneous fistula after urethroplasty,which was succesfully repaired 8 month later;16 cases were followed up average 24 months (range 7 months to 57 months),15 cases showed complete straight penis beside one case with mild curvature less than 15 degree. Conclusions The abnormalities of skin,dartos and Buck's fasciae are main causes of congenital islated penile curvature.Penile degloving,dorsal plication are main surgical methods with minimal complications.

This paper introduces chief physician LIU Huilin's empirical characteristics in treating cluster headache based on holism and pattern-identification-based treatment,with spirit-regulating filiform needling,filiform fire needle pricking,and collateral-pricking for bloodletting sequential therapy,which inherits the academic thoughts of"acupuncture-moxibustion for treating spirit"from Professor ZHOU De'an and"three-unblocking acupuncture therapy"from HE Puren,thus providing a reference for treating cluster headache with acupuncture-moxibustion therapy.

ObjectiveTo evaluate the accuracy and value of the ultrasonography and magnetic resonance imaging (MRI) in the diagnosis of agenesis of the corpus callosum in the newborns.MethodsConventional cerebral ultrasound screening was performed in 8086 newborns admitted to NICU in our hospital from January 2012 to June 2014 and agenesis of the corpus callosum was suspected or conifrmed in 31 newborns. The diagnostic accuracy of ultrasonography was assessed through the com-parison between the results of ultrasonography and MRI.ResultsIn 31 cases with suspected agenesis of the corpus callosum, ultrasonography showed 14 cases of complete agenesis of which 13 cases had the same diagnosis with MRI except one case of partial agenesis, meanwhile, ultrasonography showed 16 cases of partial agenesis of which 15 cases had the same diagnosis with MRI except one case of complete agenesis. One case of abnormal corpus callosum determined by ultrasonography was diagnosed as partial agenesis by MRI. MRI showed there were other brain malformations in 14 cases.ConclusionsUltrasonography and MRI has a high consistency in the diagnosis of agenesis of the corpus callosum in neonates, so the former can be used as a routine screening and the latter can be used as a method of accurate diagnosis. A combination of both has an important role in early diag-nosis and clinical evaluation.

Objective: To study the influences of Tiaozhixin(TZX) on NO/ET, 6 keto PGF 1a /TXB 2 and hemorrheology rats with hyperlipoidemia. Methods: The rat hyperlipoidemia and early atheroscleorsis models were established by feeding high lipid diet for 40 days. Meanwhile TZX was taken by oral administration at the dosages of 40、80g/kg. The levels of NO、ET 1、6 keto PGF 1a and TXB 2 in serum were determind, and the hemorrheology markers were observed. Results: TZX could raise the levels of NO in serumobviourly ET 1 level of the normal and model rats. The large dose of TZX could increase 6 keto PGF 1a content remarkably which benefits maintenance of the balances of 6 keto PGF 1a /TXB 2. It could lower the whole blood specific viscosity, whole blood reduction specific viscosity, plasma specific viscosity; aggregation index of RBC; shorten RBC electrophoresis time; also decrease fibrinogen content; inhibit the platelet aggregation of normal rats induced by ADP. Conclusion: TZX can improve the abnormal hemorrheology and recover the balance of TXB 2/6 keto PGF 1a and NO/ET of rats with hyperlipoidemia, which might be one of mechanisms of antiatherosclerosis action.

The nutritional and food hygienic character of the new developed soy protein concentrate and soy protein isolate in Heilongjiang province were studied by chemical analysis and rat experiment. These products have not yet been reported in China. The results indicated that the content of protein of soy protein concentrate and isolate was 69.76 and 83.11%(as anhydr-ate basic), the PER 2.00 and 1.34, the apparent digestibility 77.54 and 85.72%, the true digestibility 84.33 and 93.19%, the biological value 79.80 and 62.54%, the NPU 67.39 and 58.28% respectively.The essential amino acid composition of the two samples was the same as the products prepared in the other countries. By the hematological and pathological examination in rats, the contents of serveral harmful substan- ces were allowable or not detected. The authors belived that the nutritional quality of the two soy protein products was nearly the same as those in other countries, and its food safety was satisfactory.

Objective: To observe the clinical efficacy of warm needling moxibustion plus isokinetic muscle strength training for knee osteoarthritis (KOA).Methods: A total of 135 patients with KOA due to Yang deficiency and coagulated cold were randomized into a warm needling moxibustion group, an isokinetic muscle strength training group, and a combined group by the random number table method, with 45 cases in each group. The warm needling moxibustion group was treated with warm needling moxibustion. The isokinetic muscle strength training group was treated with isokinetic muscle strength training. The combined group was treated with warm needling moxibustion plus isokinetic muscle strength training. The Western Ontario and McMaster Universities osteoarthritis index (WOMAC) and visual analog scale (VAS) were scored before and after treatment, and isokinetic indicators of peak torque (PT), total work (TW) and average power (AP) were evaluated. Results: The total effective rate of the combined group was 92.5％, which was significantly higher than 83.3％ in the warm needling moxibustion group (P<0.05) and 72.5％ in the isokinetic muscle strength training group (P<0.05). After treatment, the scores of WOMAC (total, pain, stiffness, and function) and VAS, and isokinetic indicators (PT, TW, and AP) were all improved compared with those before treatment (P<0.05) in all three groups. The differences among the three groups were statistically significant (P<0.05). The WOMAC total score and score of stiffness in the combined group were lower than those in the warm needling moxibustion group and the isokinetic muscle strength training group (P<0.05), and the scores in the warm needling moxibustion group were lower than those in the isokinetic muscle strength training group (P<0.05). The WOMAC score of pain and VAS score in the warm needling moxibustion group and the combined group were lower than those in the isokinetic muscle strength training group (P<0.05). The differences between the warm needling moxibustion group and the combined group were not statistically significant (P>0.05). The WOMAC function score in the combined group was lower than that in the warm needling moxibustion group and the isokinetic muscle strength training group (P<0.05), while there was no statistical difference between the warm needling moxibustion group and the isokinetic muscle strength training group (P>0.05). PT, TW, and AP in the combined group were higher than those in the warm needling moxibustion group and the isokinetic muscle strength training group (P<0.05), and they were higher in the isokinetic muscle strength training group than in the warm needling moxibustion group (P<0.05). Conclusion: Warm needling moxibustion plus isokinetic muscle strength training has a better effect in the treatment of KOA due to Yang deficiency and coagulated cold than either warm needling moxibustion or isokinetic muscle strength training alone.

Objective:To observe the clinical efficacy of back-Shu and front-Mu points combination needling on balance and walking function in patients after stroke and its mechanism. Methods:A total of 79 patients with post-stroke balance and walking dysfunction were randomly divided into a control group and an observation group.Both groups received conventional treatments such as dietary guidance and oral medications as well as rehabilitation training.On this basis,the control group was treated with additional conventional acupuncture,and the observation group was treated with additional back-Shu and front-Mu points combination needling.Both groups were treated for 4 consecutive weeks.The thickness of abdominal muscle group(transverse abdominal muscle,rectus abdominis,obliquus internus abdominis,and obliquus externus abdominis),the scores of Berg balance scale(BBS),Fugl-Meyer assessment(FMA),and functional ambulation categories(FAC),and walking velocity and stride were compared between the two groups. Results:During the trial,there was 1 dropout case in the control group and 4 dropout cases in the observation group.Before treatment,there were no statistical differences in the abdominal muscle group thickness,scores of BBS,FMA,and FAC,and walking velocity and stride between the two groups(P>0.05).After 4 weeks of treatment,the thickness of abdominal muscle groups,scores of BBS,FMA,and FAC,and walking velocity and stride in both groups were improved(P<0.01),and the observation group was superior to the control group(P<0.05). Conclusion:Both conventional acupuncture and back-Shu and front-Mu points combination needling are conducive to the improvement of balance and walking function in patients after stroke.The back-Shu and front-Mu points combination needling method has better curative efficacy.Strengthening the core muscle group strength may be one of the mechanisms of back-Shu and front-Mu points combination needling treatment.
