Objective To evaluated the role of transurethral plasmakinetic resection of the prostate ( TUPKRP ) in combination with percutaneous bladder channel lithotripsy with holmium laser in the treatment of benign prostate hyperplasia ( BPH) and bladder stone in senior patients . Methods Seventy-three patients treated during January 2009 to May 2014 were retrospectively reviewed.The patients aged 70-95 years old (mean, 85.6 years old).All of the patients were complicated with one or more diseases of the cardiovascular system .Ultrasound examinations prior to operation showed the sizes of prostates ranging 35-105 g, among which 58 cases showed middle prostatic lobe protruding into the bladder cavity .The sizes of the bladder stones ranged 1.5 -4.5 cm. Results The operations were successful in all the cases .The time of lithotripsy ranged 15-50 min (mean, 24 min), and the time of prostatectomy ranged 40 -135 min (mean, 70 min).No severe complications, such as major bleeding, transurethral resection syndrome, bladder perforation, residual stones, or severe infections, were observed.The urethral catheters were removed 3-5 days after operation, without urine leakage, dysuria, or urinary incontinence.Post-operation pathology of all the cases revealed BPH .The duration of hospitalization was 5-10 d (mean, 6 d).Three months after operation, the international prostate symptom scores were decreased from (23.5 ±5.1) points to (7.5 ±1.6) points (P<0.05), the quality of life (QOL) scores were decreased from (5.1 ± 0.5) points to (2.2 ±0.8) poins (P<0.05), the maximum flow rates (Qmax) were increased from (6.2 ±2.4) ml/s to (17.9 ± 4.2) ml/s (P<0.05), and residual urine volumes were decreased from (185.6 ±29.7) ml to (30.0 ±21.2) ml (P<0.05). Conclusion Transurethral plasmakinetic resection of the prostate in combination with percutaneous bladder channel lithotripsy with holmium laser is safe and effective for the treatment of benign prostate hyperplasia and bladder stone in senior patients .

Objective To assess the performance capability of syphilis serology among STI laborato-ries in Guangdong Province. Methods Positive and negative sera samples were prepared and delivered toSTI laboratories. Non-treponemal and treponemal quantitative and qualitative tests were performed with these samples based on standardized procedures. Quality and proficiency of syphilis serology among these labora-tories were evaluated. Results A total of 225 STI laboratories in Guangdong Province participated in this survey, 3696 serological tests for syphilis were performed from 2004-2006. The outcomes showed that the total reproducibility among participating laboratories increased from 82.5% in 2004 to 90.0% in 2006 (x2 =16.8, P ＜ 0.05), and the percentage of laboratories with a performance level higher than the provincial average level rose from 64.7% in 2004 to 76.8% in 2006. The total reproducibility was 95.5% for non-treponemal qualitative tests,95.0% for treponemal qualitative tests, 82.1% for non-treponemal quantitative tests, and 81.1% for treponemal quantitative tests. The false-negativity and false-positivity rates were 4.7% and 4.0%,respectively, for non-treponemal qualitative tests, and 7.2% and 0.4%, respectively, for treponemal qualitative tests. Conclusions It is important to do capability building and improve the performance of STI laborato-ries, in order to prevent and control syphilis.

Objective To evaluate the efficacy of surgical retrieval of testicular spermatozoa,and to present the preliminary results of the retrieved testicular spermatozoa used in intracytoplasmic sperm injection (ICSI) for treatment of non obstructive azoospermic infertility. Methods Forty nine cases of non obstructive azoospermia underwent open testicular biopsy and diagnostic testicular sperm extraction (TESE).Those who had sperms in diagnostic TESE underwent ICSI at least 3 months later. Results Sperms were detected in diagnostic TESE in 12 cases (24.9%). The testicular volume,FSH level and testicular pathology did not accurately predict the presence or absence of sperm in testes.Seven (87.5%) of 8 cases had sperm in re TESE, which were used in their ICSI cycles,resulting in 3 clinical pregnancies. Conclusions The diagnostic TESE should be performed to determine the presence or absence of testicular spermatozoa in testicular failure before ICSI,and the surgically retrieved testicular spermatozoa can be adopted in ICSI for treatment of non obstructive azoospermic infertility.

Objective To investigate the clinical efficacy of heat-sensitive point moxibustion plus manipulative reduction in treating thoracic facet joint disorder. Method A single-blind randomized controlled trial was carried out. Eighty-two patients meeting the criteria were randomly allocated to an observation group of 42 cases and a control group of 40 cases. The observation group received heat-sensitive point moxibustion plus manipulative reduction and the control group, TDP plus manipulative reduction. Both groups were treated five times a week, five times as a course for a total of two courses (including the patients cured after less than two courses). The therapeutic effects were evaluated by using the McGill Pain Questionnaire the as the observation index, comparing pre-/post-treatment Pain Rating Index (PRI) scores, Visual Analogous Scale (VAS) scores and Present Pain Intensity (PPI) scores and referring to the Criteria of the Diagnosis of and the Therapeutic Effect on Syndromes in Traditional Chinese Medicine. Result After treatment, the PRI, VAS and PPI scores decreased significantly in both groups (P<0.01) and were lower in the observation group than in the control group (P<0.01). The cure rate was 57.1% (24/42) in the observation group, which was significantly higher than 27.5% in the control group (11/40,P<0.01). The total efficacy rate was 95.2% (40/42) in the observation group, which was significantly higher than 80.0% in the control group (32/40,P<0.01). Conclusion Heat-sensitive point moxibustion plus manipulative reduction has a very good therapeutic effect on thoracic facet joint disorder. The effect is significantly better than that in the control group.

Objective: To evaluate the effects of functional appliance and multi-bracket appliance on Angle Class II malocclusions coupled with vertical and transversal problems. Methods:Headgear-activator, Herbst appliance and multi-bracket appliance were used to treat 20 patients with Class II malocclusions coupled with vertical and transversal problems aged from 10 to 15 years. The lateral cephalograms were measured with Winceph 8. 0 software and statistical analysis was carried by SPSS 13. 0 software. Results:The sagi-tal, vertical, transversal problems had mainly been resolved at the end of functional appliance treatment. The SNB were increased( P<0. 05), ANB were decreased(P<0. 05), upper posterior teeth were intruded and distally moved(P<0. 05), lower posterior teeth were extruded and mesialy moved(P<0. 05). After multi-bracket appliance treatment, the anterior teeth achieved normal overbite and over-jet. The molar relationship changed from class II to class I. Mandibular plane angle was not clockwise rotated(P>0. 05). The upper and lower dentition were harmony in sagital, vertical and transversal. Conclusion: Functional appliance combined with multi-bracket appliance can be used effectively and conveniently for the treatment of Class II malocclusions coupled with vertical and transversal prob-lems.

There were statistically significant pre-/post-treatment differences in the pain score, the neck disability index, and cervical active range of motion and isometric muscle strength in the two groups (P<0.01,P<0.05). There were statistically significant post-treatment differences in the neck disability index, and cervical active range of motion and isometric muscle strength between the treatment and control groups (P<0.05).Conclusions Electroacupuncture plus a multi-function cervical rehabilitation system is an effective way to treat cervical spondylosis. It can relieve the clinical symptoms in the patients.

BACKGROUND:The important reason for failed back surgery syndrome is the postoperative epidural scar adhesions, therefore, exploring the methods of preventing postoperative lumbar epidural scar adhesions has always been a hot research in spine surgery field. OBJECTIVE:To investigate the effect of Shenshu point magnetic stimulation therapy on epidural scar adhesions in rat models of failed back surgery syndrome. METHODS:Sixty Sprague-Dawley rat models of failed back surgery syndrome were successfuly established using the method of laminectomy, and then divided into Shenshu magnetic therapy group and blank control group. Beginning from 1 week after modeling, rats in the Shenshu magnetic therapy group were subjected to bilateral Shenshu magnetic stimulation for 6 weeks, 5 days of treatment per week. Rats in the blank control group were not given any intervention. At 13 weeks after modeling, rats were harvested and the area ratio of epidural scars, range of adhesions and formation of colagen fibers were observed under light microscope. Fibroblasts were counted. Hydroxyproline content and transforming growth factor β1 expression in scar tissue were compared between these two groups.

BACKGROUND:The chemical compositions and structure of calcium phosphate bone cement are similar to those of human bone, which can fil the bone colapse caused by fracture and induce osteogenesis, but its degradation rate is slow. OBJECTIVE:To evaluate the biocompatibility of the calcium phosphate cement/fibrin glue and the feasibility of repairing radius defects. METHODS: In vitro cytotoxicity experiment: Mouse fibroblasts were cultured in the calcium phosphate bone cement/fibrin glue extracts, phenol solution, and RPMI 1640 culture medium containing 10% fetal bovine serum, respectively, to detect the cytotoxicity grade. Hemocompatibility experiment: Calcium phosphate bone cement/fibrin glue extracts, normal saline and distiled water were respectively added into the rabbit anticoagulation, to detect the hemolytic rate. Forty-five New Zealand white rabbits were enroled and modeled into bilateral radius defects, folowed by randomly alotted into three groups: blank control group without any intervention, experimental and control groups were given the implantation with calcium phosphate bone cement/fibrin glue and autologous radius, respectively. X-ray, histology, bone mineral density and biomechanical test were performed at postoperative 4, 8 and 16 weeks. RESULTS AND CONCLUSION:The toxicity grade of the calcium phosphate cement/fibrin glue was 0 to 1. The hemolytic rate of the calcium phosphate cement/fibrin glue was 3.15%. At 16 weeks postoperatively, X-ray showed that in the experimental and control groups, the fracture line disappeared completely, pulp cavity was recanalized, and in plastic completely. Histology showed that the reconstructed bone trabecular was obvious, plate layer of bone was mature, and medulary cavity recanalization appeared in the control group; there were a large number of new grid-shaped woven bone tissues growing into the material in the experimental group, with overt degradation, and degradation rate was in paralel to bone ingrowth. The bone density, the maximum load, maximum stress and failure energy in the experimental and control groups were significantly higher than those in the blank control group (P < 0.05), and al above indicators showed no significant differences between the experimental and control groups. These results manifest that the calcium phosphate bone cement/fiber protein glue composite material holding a good biocompatibility can promote bone tissue regeneration for bone defect repair, achieving similar curative effect with autologous bone transplantation.

Objective To observe the clinical efficacy of bamboo-circled salt-partitioned moxibustion in treating arthritis of temporomandibular joint.Method Eighty patients were randomized into two groups. Forty cases in the bamboo-circled salt-partitioned moxibustion group received bamboo-circled salt-partitioned moxibustion at temporomandibular joint; forty cases in the warm needling group were intervened by selecting Xiaguan (ST7), Ashi point, etc. at the affected side. For the two groups, 3-day treatment was taken as a treatment course, and the therapeutic efficacy was analyzed after 2 treatment courses. The improvements in pain and mouth opening were observed before and after the treatment, and the treatment efficacy was evaluated by a 1-month follow-up study.Result The bamboo-circled salt-partitioned moxibustion group was superior to the warm needling group in comparing the real-time analgesic effect (P<0.05) and in the improvement of mouth opening (P<0.05); the comprehensive markedly effective rate was respectively 67.5% and 45.0% in the bamboo-circled salt-partitioned moxibustion group and warm needling group, and the between-group difference was statistically significant (P<0.05), indicating that bamboo-circled salt-partitioned moxibustion is better than warm needling in treating arthritis of temporomandibular joint; the follow-up study revealed satisfactory therapeutic efficacies in both groups: the effective rate was 92.5% in the bamboo-circled salt-partitioned moxibustion group versus 87.5% in the warm needling group, and the difference was statistically insignificant (P>0.05).Conclusion Bamboo-circled salt-partitioned moxibustion can produce a real-time analgesic effect and improve mouth opening; it's especially suitable to treat the patients who are afraid of needling, as it's significantly effective, safe, non-invasive,and easy-to-operate.

Objective To investigate the significance of preoperative and postoperative enteral nutrition support in gastric cancer patients with nutritional risk.Methods The clinical data of 72 gastric cancer patients with nutritional risk admitted in our department were analyzed.All the patients were randomly allocated into two groups.36 patients in the control group received only intravenous nutrition postoperatively (PN group).36 patients in the treatment group received enteral nutrition support from the fifth day before operation to eighth day after operation (EN group).The body weight,total protein,albumin,transferrin and prealbumin were measured on the fifth day before operation,the operation morning,the first day and the eighth day after operation.Results On the operation morning,the transferrin and prealbumin of the EN group were higher than those in PN group significantly(P ＜0.05).In the eighth day after operation.the treatment group patients showed significant increase in the body weight,total protein,albumin,transferrin and prealbumin compared with those in the control group(P ＜ 0.05).On the operation morning,the transferrin and prealbmnin of EN group were increased significantly than on the fifth day before operation(P ＜ 0.01).Conclusion The preoperative and postoperative enteral nutritional support can improve the nutritlonal condition in the gastric cancer patients with nutritional risk.The preoperative enteral nutritional support can improve the patients' nutritlonal condition and reserves before operation,and reduce adverse reaction of enteral nutrition.
