ABSTRACT
OBJECTIVE@#To observe the clinical effect of transforaminal endoscopy combined with interspinous fusion in the treatment of lumbar spinal stenosis with instability in the elderly.@*METHODS@#From February 2018 to February 2019, 82 elderly patients with lumbar spinal stenosis and instability were divided into control group and observation group. In the control group, there were 23 males and 18 females;the age was (68.9±4.1) years;the course of disease was (14.1±5.7) months;there were 5 cases of single segment lesions and 36 cases of multi segment lesions;simple bacfuse interspinous fusion was used. In the observation group, there were 22 males and 19 females;the age was (69.1±4.0) years;the course of diseasewas (14.4±5.5) months;there were 6 cases of single segment lesions and 35 cases of multi segment lesions;they were treated with transforaminal endoscopic surgery combined with Bacfuse interspinous fusion. The clinical efficacy, visual analogue scale (VAS), Japanese Orthopaedic Association scores (JOA), Oswestry disability index (ODI), Lehmann lumbar function score, posterior disc height and intervertebral foramen height, complication rate and recurrence rate of the two groups were compared.@*RESULTS@#The clinical efficacy of the observation group was better than that of the control group;the VAS score of the observation group was lower than that of the control group, the JOA score was higher than that of the control group, and the ODI index at 3 months after operation and at the last follow-up was lower than that of the control group, the Lehmann lumbar function score was higher than that of the control group;the posterior edge height of intervertebral disc and intervertebral foramen height were higher than those of the controlgroup;the incidence of complications and recurrence rate (4.9% and 0.0%) of the observation group were lower than those of the control group (19.5%, 9.8%), the difference was statistically significant (@*CONCLUSION@#The clinical effect of transforaminal endoscopy combined with interspinous process fusion in the treatment of lumbar spinal stenosis with instability in the elderly is ideal. It can reduce postoperative pain, improve lumbar function, improve the height of posterior edge of intervertebral disc and intervertebral foramen, and reduce the incidence and recurrence rate. It is worthy of clinical promotion.

OBJECTIVE@#To explore clinical effect of modified transverse tibial bone transfer microcirculation reconstruction in treating end-stage diabetic foot.@*METHODS@#From August 2016 to June 2018, 87 patients with diabetic foot treated with modified tibial transverse bone removal and microcirculation reconstruction, inclduing 54 males and 33 females;aged from 39 to 95 years old with an average of (68.9±11.3) years old;2 patients were grade 2, 37 patients were grade 3 and 50 patients were grade 4 according to Wagner's classification;the courses of diabetic were for 10 to 16 years with an average of (13.0±2.2) years;the courses of diabetic feet were for 21 to 48 days with an avergae of (34.2±8.6) days. Postoperative comlications were observed. Skin temperature, visual analogue scale(VAS) and ankle brachial index(ABI) and wound healing were recorded before and 3 months after operation.@*RESULTS@#All patients were followed up for 4 to 19 months with an average of (12.6±2.8) months. Two patients occurred subcutaneous tissue liquefaction and seepage under needle passage during bone transfer, and scabed without special treatment. One patient was performed amputation above 5 cm of ankle joint because of severe infection, and 1 patient occurred re-ulceration at 1 year after wound healing, bone transfer was performed again at the same site, and was completely healed at 8 weeks after operation. The healing time of wound ranged from 3 to 24 weeks with an average of (11.9± 3.8) weeks. Foot skin temperature before operation was (28.9±0.91) ℃, and increased to (31.70±0.32)℃ at 3 months after operation(@*CONCLUSION@#Modified lateral tibial bone transfer could effectively reconstruct microvascular network under lower leg, promote recovery of peripheral blood vessels, and promote wound healing of foot, reduce or avoid amputation. At the same time, the improved osteotomy is one of the effective methods for the treatment of diabetic foot which has advantags of less trauma, simple opertaion.

<p><b>OBJECTIVE</b>To further study the therapy of wasting muscle by myostatin as a new targets, the eucaryotic expression vector coupled the foreign T-helper epitope of tetanus toxin (TT) to the N terminus of myostatin was constructed, and the effects of the gene vaccine on forelimb grip were tested in immunized mice.</p><p><b>METHODS</b>A DNA fragment encoding the TT epitope followed by the N terminus of mature myostatin (330bp) was synthesized. The eucaryotic expression vector of myostatin was constructed and the chinese hamster ovary (CHO) cells were infected with the recombinant plasmids pVAC-TT-Ms by liposome transfection according to routine laboratory procedure. The myostatin expression was tested by cell immunofluorescence technique in transfected CHO. The forelimbs grip were tested in immunized mice with myostatin gene vaccine.</p><p><b>RESULTS</b>The eucaryotic expression vector of myostatin coupled TT epitope was constructed successfully through the restriction analysis and sequencing. The recombinant plasmids pVAC-TT-Ms met quality criterion as gene vaccine by analysis OD260/280 and electrophoresis. The myostatin expression was detected obviously in transfected CHO. The forelimb grip in immunized mice had an obvious increase. The average value of forelimb grip of the mice immunized with pVAC-TT-Ms was about 29.88% greater than that of control mice.</p><p><b>CONCLUSION</b>The construction of eucaryotic expression vector of myostatin coupled TT epitope is successful in expression for recombinant human mature peptide of myostatin. The gene vaccine of myostatin meet quality criterion. The immunized mice has an obvious increase in forelimb grip.</p>

<p><b>OBJECTIVE</b>To investigate seminal parameters in noninflammatory chronic prostatitis/chronic pelvic pain syndrome (CAP III B).</p><p><b>METHODS</b>A total of 74 consecutive cases of patients who had been diagnosed as CAP III B and 46 cases of controls were included in the study. Severity of symptoms in men with CAP III B was defined according to the NIH Chronic Prostatitis Symptom Index (NIH-CPSI). All of them underwent a 'four glass-test' including leukocyte determination in expressed prostatic secretions (EPS), voided urine after prostatic massage (VB3) and ejaculate semen followed by analysis according to WHO. The analysis included seminal volume, pH, duration of liquefaction, sperm density, vitality, motility(a + b) and morphology. Correlations between the duration or the severity of symptoms and spermiogram results in patients with CAP III B were assessed respectively.</p><p><b>RESULTS</b>The CAP III B group and the control group differed significantly in ejaculate volume, duration of liquefaction and motility, while the remaining parameters did not differ significantly. The duration of chronic pelvic pain showed apparently positive correlationship with liquefaction time, while the symptom duration negatively correlated with sperm motility. The NIH-CPSI score had no significant relationship with seminal volume, duration of liquefaction and sperm motility.</p><p><b>CONCLUSION</b>Our results indicate that CAP III B can have a significant negative impact on sperm volume, liquefaction and motility. Our data also supports the results that the longer the duration of symptoms, the more influences on semen liquefaction and motility might be.</p>

<p><b>OBJECTIVE</b>To improve Madigan prostatectomy (MPC) for a much satisfactory effect in open surgery.</p><p><b>METHODS</b>A total of 52 patients with benign prostatic hyperplasia (BPH) were treated using MPC. The MPC procedure was modified by exposing anterior prostatic urethra near the bladder neck and conjunction with cystotomy. This modified procedure preserved prostatic urethra intact and could also deal with intracystic lesions at the same time.</p><p><b>RESULTS</b>The intact of prostatic urethra was kept completely or almost for 48 cases. The hemorrhage amount during modified procedure was a less. The mean operative time was 120 minutes. The 35 patients had been followed up for 1 - 12 months. The average Qmax was 18.9 ml/s. The cystourethrography revealed that the urethra and bladder neck were intact in 8 patients postoperatively. Furthermore, the prostatic urethra was obviously wider after modified MPC.</p><p><b>CONCLUSIONS</b>The modified MPC can reduce the urethra injury and enlarge the MPC indications. The modified technique is easy to perform with little complications and much more satisfactory clinical result. The modified MPC is highly recommended.</p>

<p><b>OBJECTIVE</b>To compare the complications of direct and antirefluxing techniques of ureterointestinal anastomosis in continent urinary diversion.</p><p><b>METHODS</b>Sixty-three patients underwent continent urinary diversion. Twenty-four patients were treated by the direct ureteroenteric anastomosis and the others treated by the antirefluxing technique. The follow up studies included following-up the information of ureteric stricture, ureteric reflux, renal function and acute urinary infection. It was assessed for 3 months to 6 years with a mean follow up of 26 months after operation.</p><p><b>RESULTS</b>Of 78 ureters reimplanted using antirefluxing technique. A total of 12 ureters had anastomotic stricture formation postoperatively. Only one of 48 ureters reimplanted using direct anastomoses had anastomotic stricture. The difference between the direct and antirefluxing technique groups was remarkable (chi2 = 4.375, P < 0.05). Furthermore, there was no significant difference between the direct and antirefluxing technique groups in regard to ureteric reflux, renal function and acute urinary infection.</p><p><b>CONCLUSIONS</b>Antirefluxing anastomoses resulted in obviously higher rate of ureterointestinal anastomotic stricture in comparison with the direct anastomosis. The direct ureteroenteric anastomosis may be the suitable choice for patients undergoing continent urinary diversion.</p>
