AIM: To observe the surgical effects of the taumatic lens subluxation and cataract after manual fragmentation and emulsification of nucleus and foldable intraocular lens implantation.
METHODS: A 3. 0mm tunnel limbus incision was operated through the predicted bulbar conjunctiva and sclera on 26 cases ( 26 eyes ) with taumatic lens subluxation ( suspensory ligament rupture range less than 120 ) and cataract (Ⅰ ~ Ⅲ) . And after the manual fragmentation and emulsification of nucleus, foldable intraocular lens was implantated. Intraocular lens loop was imbedded in the middle of the lens zonular ligament breakup to reset the pouch. The surgical complications and postoperative vision changes were observed.
RESULTS:Three month after operation, 22 eyes had a intraocular lens centric position taking up 85% of the whole. Four eyes had a slightly eccentric position ( 1 ~2mm), taking up 15% of the whole. 21 eyes had their visual acuity 0. 5~0. 8, taking up 81% of the whole. Five eyes of visual acuity was 0. 2~0. 8. Within 24h intraocular pressure of 12 eyes (46%) after operation were elevated, and returned to normal after 2~7d. There was no severe complication during operation and postoperation.
CONCLUSION: The manual fragmentation and emulsification of nucleus and foldable intraocular lens implantation of the traumatic lens subluxation and the cataract through the 3. 0mm corneal sclera limbus tunnel incision is a simple and effective surgery.

OBJECTIVETo investigate the efficacy of the Chinese medicine Huzhangdanshenyin on male immune infertility, and provide an effective therapy for this disease.

METHODSNinety men with immune infertility were selected as the research subjects and randomly divided into two groups, 60 in the treatment group, treated by Huzhangdanshenyin, and the other 30 in the control, treated by prednisone, both for 3 months. The improvement of clinical symptoms, immunologic indexes (antisperm antibodies in serum and seminal plasma) and sperm indexes (semen liquefied duration, motility, viability, density and abnormal morphology rate) were observed and the results analyzed.

RESULTSThe total antisperm antibody reversing ratio of the treatment group was higher than that of the control (P < 0.01), especially the serum antisperm antibody reversing ratio. There were significant differences in the clinical cure rate and total validity rate between the treatment group and the control (P < 0.01). After the treatment, the markers of the clinical symptoms (P < 0.01), especially the serum antisperm antibody reversing ratio. There were significant differences in the clinical cure rate and total validity rate between the treatment group and the control (P < 0.01). After the treatment, the markers of the clinical symptoms were lower (P < 0.01), and the improvement of the clinical symptoms was better in the treatment group than in the control (P < 0.01), especially the symptoms of pain in the back and knees, distending and bearing-down sensation of the perineum and testis, hypersexuality and topalgias. Compared with pre-treatment, sperm motility and viability of the treatment group significantly improved (P < 0.01), and so did sperm density (P < 0.05). However, there were no significant differences in sperm density, semen liquefied duration, abnormal morphology rate and pH (P > 0.05) before and after the treatment.

CONCLUSIONThe Chinese medicine Huzhangdanshenyin works more effectively than prednisone in the treatment of male immune infertility. It could improve the antisperm antibody reversing ratio, clinical symptoms and signs and ameliorate sperm indexes with no obvious advierse effects.

OBJECTIVETo add DXS7133, GATA198A10, DXS9896 and DXS6797 to the panel of forensically validated X chromosome markers, and apply the multiplex amplification system to a population study and forensic analysis on the Hans of Chengdu.

METHODSThe PCR products were detected by the polyacrylamide gel electrophoresis and silver staining method. Hardy-Weinberg equilibrium of females was tested and every forensically interested value was calculated.

RESULTSSequencing revealed that their common sequence motifs were tetranucleotide repeats. Population genetic data were obtained by analyzing 120 unrelated females and 100 males from Chengdu Han ethnic group. In this population, DXS7133, GATA198A10, DXS9896 and DXS6797 exhibited 6, 6, 11, 8 distinguishable alleles respectively. Chi-square test demonstrated that genotype frequencies in females did not depart from Hardy-Weinberg equilibrium. Power of discrimination for female samples for the four loci were 0.7962, 0.8021, 0.9675, and 0.9444. The parentage testing in 32 cases revealed a typical X-linked inheritance and no mutations.

CONCLUSIONDXS7133, GATA198A10, DXS9896 and DXS6797, which are highly polymorphic in Chengdu Han population, are appropriate for individual identification and paternity testing involving a female child.

OBJECTIVETo solve the problems in the accuracy and standardization of short tandem repeats-polymerase chain reaction (STR-PCR) typing, the authors adopted the molecular clone technology in producing the standard allelic ladders of D1S1676, D2S2735, D11S1977 and D22S444 loci and applied them in a population study on the Hans in Chengdu, China.

METHODSPCR was used to produce several different allelic fragments of these loci. PCR products were eluted from the gel and re-amplified by PCR. The purified allelic fragments were then blunt-end subcloned individually into the pGEMR-T plasmid vectors and the recombinant were transfected into competent E.coli DH5alpha TM cells. The results of sequencing confirmed that the size and the construction of the inserts were correct. The recombinant plasmids DNA with the inserts were then used as template for re-amplification to generate the four loci standard ladders.

RESULTSThe authors succeeded in producing large quantity of standard allelic ladder of these four loci, with which the genetic polymorphisms of these loci in Chengdu Han population of China were studied.

CONCLUSIONThis method is of high value for forensic DNA typing to construct standard ladders. D1S1676, D2S2735 loci are robust for forensic analysis in Chinese Han population, whereas the value of D11S1977 and D22S444 loci is limited.

OBJECTIVETo explore the techniques of esophagogastrostomy or esophagojejunostomy in the mediastinum through the abdomen and hiatus after extended proximal gastrectomy or total gastrectomy.

METHODSFrom May 2010 to January 2012, 15 patients with esophagogastric junction carcinoma underwent open transhiatal extended gastrostomy or total gastrectomy. After full mobilization, the anvil was reversely introduced into the esophagus and the esophagus was transected with curved stapler. The rod of the anvil was then pulled out with a stitch to complete esophagogastrostomy after proximal gastrectomy(n=9) or esophagojejunostomy after total gastrectomy(n=6).

RESULTSThe anastomosis was successfully performed in all the patients. The mean operation time was(185.5±13.1) min. The mean operation time for anastomosis was(42.0±8.6) min. The mean estimated blood loss was (106.7±34.9) ml. The proximal resection margin was(4.4±1.2) cm. All the margins were negative for residual cancer. There was no postoperative death or fistula. During the follow up, there was one case of anastomotic stenosis which was successfully managed by endoscopic balloon dilatation.

CONCLUSIONSEsophagogastrostomy or esophagojejunostomy can be safely performed with double stapling technique including reverse anvil introduction and curved stapling transection of the esophagus. It is an ideal technique for anastomosis after extended gastrectomy for esophagogastric junction carcinoma.

OBJECTIVETo explore the application of the spiral computerized tomography (CT) image three-dimensional (3D) reconstruction technique associated with the conventional radiography in the diagnosis and treatment of severe talar neck fracture.

METHODSUsing the multi-slice spiral CT image 3D reconstruction technique, we analysed 11 cases of talar neck fracture. The fractures were reduced and fixed through a minimal incision and internal fixation with titanium cannulated lag screws.

RESULTSIn the 11 cases, the results of CT image 3D reconstruction were in concordance with plain radiograph in 6 case of Hawkins type II. And the remaining 5 cases of Hawkins types III and IV could not be classified exactly only by radiographs, one of whom was misdiagnosed. After using the CT image 3D reconstruction, the 5 cases were classified exactly before osteosynthesis. The classifications of these 11 cases were confirmed finally by surgical findings. The duration of operation were 45-140 min, averaging 81 min (including the duration of C-arm fluoroscopy). X-ray exposure time was 6-58 seconds, averaging 22 seconds. The blood loss was less than 100 ml. The fracture union was achieved in 3 months. No nonunion, talus avascular necrosis or joint surface collapse occurred. Postoperative follow-up was from 1 to 25 months. According to Hawkins score, excellent result was found in 6 type II cases and 1 type III case; good result in 1 type III case with both medial and lateral malleolar fracture, 1 type III with medial malleolus fractures and 1 open type III; fair result in 1 open type IV with lateral malleolus fracture.

CONCLUSIONSBy using the multi-slice spiral CT image 3D reconstruction associated with radiography to diagnose and treat severe talar neck fractures, the accuracy of diagnosis can be improved obviously. Based on this technique, more consummate operational plan can be designed and performed so as to achieve a better therapeutic effect.

OBJECTIVETo assess the value of application of percutaneous radiofrequency ablation (RFA) with artificial hydrothorax for liver cancer in the hepatic dome.

METHODSThirty-two patients with 43 lesions of hepatic malignant tumors in the hepatic dome underwent ultrasound-guided percutaneous radiofrequency ablation (RFA) with artificial hydrothorax. Artificial hydrothorax was created by infusion of saline via an intrathoracically placed 14-G central venous catheter, which was ultrasound-guided percutaneously inserted before RFA, separating the right lung from the hepatic dome. The adverse reaction and therapeutic efficacy were also analyzed.

RESULTSIn the 32 patients with 43 lesions in the hepatic dome (4 tumors in segment IV 21 tumors in segment VII and 18 tumors in segment VIII), 18 lesions of 14 patients were not observed by ultrasound before the operation. Thirty-two patients received the ultrasound-guided placement of intrathoracical catheter, and (1606.3 ± 485.9) ml (1000 - 2500 ml) saline solution was infused successfully. After obtaining an image of the whole tumor, 31 patients received percutaneous RFA therapy on schedule, and 22 patients received percutaneous transdiaphragmatic RFA therapy. One patient with 2 lesions gave up the treatment, because one of his tumors was not detectable by ultrasound. Diaphragmatic muscle hemorrhage was seen in two patients, subcutaneous edema in two patients, and pneumothorax in one patient. All the complications were cured, and no serious complications or related death occurred. 1-month follow-up with contrast-enhanced CT/MRI images showed that 29 patients had complete ablation, and the effective rate of this technique was 93.5% (29/31).

CONCLUSIONSArtificial hydrothorax helps us not only to visualize the whole tumor in the hepatic dome, but also offers a transdiaphragmatic route for therapy. Ultrasound-guided percutaneous RFA with artificial hydrothorax is a feasible, safe, and effective technique for treating liver cancer in the hepatic dome and worthy of being promoted.
