Clinical Observations on Knife Needle Microinvasive Operation for Cervical Spondylotic Arteriopathy / 上海针灸杂志

Objective To investigate the clinical efficacy of knife needle microinvasive operation for cervical spondylotic arteriopathy. Method Sixty patients with cervical spondylotic arteriopathy were randomized, in order of admission times, to observation and control groups, 30 cases each. The observation group received three-step knife needle microinvasive operation and the control group, single suboccipital deltoid muscle lysis. The therapeutic effects were compared between the two groups of patients. Result In the two groups of patients the score changed significantly at the end of and three months after treatment compared with before and had a tendency towards gradual increase (P<0.05). The score difference values between pre-treatment and post-treatment and between post-treatment and three-month follow-up were significantly higher in the observation group than in the control group (P<0.05). Repeated measurement analysis integrogram showed significant differences in the scores between the two groups. The total efficacy rate was significantly higher in the observation group (96.7%) than in the control group (76.7%) (P<0.05). Conclusion Knife needle microinvasive operation has clinically a marked therapeutic effect on cervical spondylotic arteriopathy.

Penile necrosis resulting from post-circumcision microwave diathermy: A report of 9 cases / 中华男科学杂志

<p><b>OBJECTIVE</b>To investigate the pathogenesis and treatment of penile necrosis resulting from microwave diathermy following circumcision.</p><p><b>METHODS</b>We retrospectively analyzed the clinical data about 9 cases of penile necrosis resulting from postoperative microwave diathermy following circumcision. The 9 males, aged 20 - 39 (mean 26) years, underwent traditional circumcision for redundant prepuce or phimosis in other hospitals, followed by microwave diathermy for 30 - 60 minutes daily, which resulted in penile necrosis. With no response to conservative therapy, the patients were referred to our hospital at 3 -30 days postoperatively. Of the 9 patients, 5 presented with dry gangrene and 4 with moist gangrene. Six of the patients underwent partial penectomy, including 1 that received penis lengthening.3 months later, while the other 3 underwent total penectomy for total penile necrosis followed by penile reconstruction 3 months later, with deep inferior epigastric perforator (DIEP) flaps and by implantation of the 12th costal cartilage in 2 cases and with epigastric groin island flaps and by urethroplasty in the other.</p><p><b>RESULTS</b>The patients were followed up for 2 - 8 years, and all could urinate smoothly in the standing position. Of the 6 men treated by partial penectomy, 1 received penis lengthening and achieved a penile length of 7 cm and 5 had the remaining penile length of 3 -5 cm, 4 with erectile function and the other 2 capable of sexual intercourse. The 3 men treated by total penectomy achieved nearly normal external appearance of the penis, with a finalized length of (11.7 ± 1.3) cm, a circumference of (11.4 ± 2.1) cm, and a normal feel of the skin. Of the 3 cases of penile reconstruction, 2 achieved sufficient erectile hardness of the penis (grade 3) for sexual intercourse, while the other 1 remained impotent.</p><p><b>CONCLUSION</b>Post-circumcision microwave diathermy may result in penile necrosis, for the management of which, early debridement is necessitated and penile lengthening or reconstruction can be performed according to the severity of the lesion and needs of the patient.</p>

Probe into construction mode of wound care center / 中华烧伤杂志

Relevant data including diagnosis and treatment model, operation situation, etc. are analyzed in our wound care center and compared with abroad based-on literature retrieval, to find out a suitable way for setting up wound care centers in our country. Wound care center with mode of multidisciplinary cooperation that is "specialist-oriented" was established in our hospital, mirroring the experience of foreign wound care centers. The investigation showed the demands of patients could be met, their psychological and economic pressures as well as social burden might be greatly relieved in our center. For an example, we achieved our purpose readily by setting up a clinical pathway of diabetic foot according to the features of our hospital. The model of multidisciplinary cooperation, with minor adjustments, may be applicable for wound care centers at home and abroad. Our wound care center will establish better system of diagnosis and treatment to conform to the situation in our country.

Prevention and treatment of the complications of inflatable penile prosthesis implantation / 中华男科学杂志

<p><b>OBJECTIVE</b>To report the amelioration of the three-piece inflatable penile prosthesis (IPP) implantation and the prevention of its complications.</p><p><b>METHODS</b>Thirty-two patients with moderate to severe erectile dysfunction (ED) irresponsive to conservative treatments received the implantation of the three-piece IPP. The surgical techniques were ameliorated in the course of operation. The patients were guided in using the IPP after operation. The effects and complications of the implantation were observed based on IIEF of the patients before and after operation.</p><p><b>RESULTS</b>Sexual life was resumed and no complication was found in 28 of the patients. The complications that developed in the other 4 were pump failure (2 cases), urethral perforation (1 case), and penis contraction (1 case). The former 3 achieved normal sexual intercourse after the second operation. Comparison between the IIEF scores before and after operation showed a very remarkable difference (P < 0.01). The occurrence rate of complications was 12.5%. The satisfaction rate of sexual intercourse was 87.5% and the total satisfaction rate of sexual life was 84.4%.</p><p><b>CONCLUSION</b>The complications of the three-piece IPP implantation were obviously reduced by ameliorating operation techniques. The implantation of the three piece-IPP is safe and effective for advanced ED patients.</p>

Types and emergence time of YMDD motif mutation in hepatitis B virus polymerase gene during lamivudine treatment / 中华肝脏病杂志

<p><b>OBJECTIVE</b>To study the types and emergence time of YMDD motif mutation in hepatitis B virus (HBV) polymerase gene during lamivudine treatment.</p><p><b>METHODS</b>The serum samples were collected from 33 patients with HBV DNA rebounding and 2 non-responders after at least one year lamivudine treatment. HBV polymerase gene was amplificated by PCR, then the products were detected by restriction fragment length polymorphism (RFLP) and by direct sequence analysis.</p><p><b>RESULTS</b>The variants with YMDD mutation were 14 out of the 35 patients. Mutation patterns detected in these patients included four YIDD, six YVDD, three YI/VDD and one YI/MDD. The mean emergence time of YMDD variants was 11.07+/-3.65 months after the treatment, and the earliest one and the latest one occurred 5 months and 17 months after the treatment respectively. The emergence times of YIDD, YVDD, YI/VDD were (10.00 +/- 1.41) months, (11.67 +/- 4.41) months and (13.33 +/- 3.31) months respectively, which had no statistical significance (F = 0.543, P < 0.05). Three patients treated with lamivudine 200 mg every day after the mutation were followed up for 6 months, whose HBV variants had not vanished.</p><p><b>CONCLUSIONS</b>There are many kinds of HBV variants after lamivudine treatment, including YIDD, YVDD, YI/VDD and YI/MDD. The emergence time of variants is quite variable between different types and the mean time is (11.07 +/- 3.65) months after treatment, and there is no relationship between the type of YMDD mutation and the time of lamivudine administration.</p>
