OBJECTIVETo evaluate the efficacy and safety of the combination therapy of Xipayimaizipizi Capsules and Tamsulo- sin in the treatment of benign prostatic hyperplasia (BPH).

METHODSWe randomly assigned 60 BPH patients to a control and a combination group of equal number, the former aged 62.03 ± 10.19 years with a disease course of 3.24 ± 2.18 years and the latter aged 64.77 ± 10.33 years with a disease course of 4.09 ± 2.63 years. We treated the patients in the control group with Tamsulosin at 0.2 mg qd and those in the combination group with Tamsulosin at 0.2 mg qd plus Xipayimaizipizi at 0.5 g tid, respectively, both for 4 weeks. Then, we obtained the mean frequency of nocturnal urination, maximal urinary flow rate (Qmax), residual urine volume, International Prostate Symptom Score (IPSS) , and quality of life scores (QOL) of the patients, and recorded their adverse reactions.

RESULTSBefore treatment, the nocturnal urination frequency, Qmax, IPSS, and QOL were 3.60 ± 1.81, (10.40 ± 3.53) ml/min, 22.47 ± 8.58, and 4.43 ± 1.50 in the control group, as compared with 3.43 ± 1.61, (10.14 ± 3.43) ml/min, 21.93 ± 8.79, and 4.73 ± 1.31 in the combination group. After 4 weeks of medication, the combination group showed more significant improvement than the control in the nocturnal urination frequency (1.30 ± 1.18 vs 2.27 ± 1.60), Qmax ([13.85 ± 3.15] vs [14.36 ± 3.03] ml/min), IPSS (13.00 ± 1.53 vs 17.20 ± 8.43), and QOL (2.57 ± 1.61 vs 2.93 ± 1.68), all significantly better than the baseline (P < 0.05). The combination therapy achieved remarkable improvement as compared with the control in the nocturnal urination frequency (- [2.13 ± 1.11] vs -[1.73 ± 1.07]), IPSS (- [8.93 ?6.01] vs -[4.80 ± 3.87]), and QOL (- [2.17 ± 1.12] vs -[1.50 ± 1.01]) (P < 0.05), but exhibited no significant differences from the latter in Qmax ([3.72 ± 2.281 vs [3.95 ± 2.53] ml/min) and residual urine volume (- [34.30 ± 37.43] vs - [26.43 ± 30.49] ml) (P > 0.05). Adverse reactions were found in 5 cases in the combination group (16.67%) and 3 cases in the control (10%) , with no remarkable differences between the two groups (P > 0.05).

CONCLUSIONThe combination therapy of Xipayimaizipizi Capsules and Tamsulosin can improve the symptoms of BPH and the patients quality of life of.

Objective To explore the efficacy of arthroscopic treatment for acute avulsion fracture of posterior cruciate ligament (PCL) using double titanium plate TightRope. Methods From December 2014 to January 2015, two cases with acute avulsion fracture of PCL were treated with double titanium plate TightRope under arthroscopy, after assessment of three dimensional reconstructive CT and MRI. Rehabili-tation was carried out after operation. Results One case succeeded with double titanium plate TightRope, and rehabilitation could be per-formed early postoperatively. Another case failed in TightRope fixation, and accepted two internal hollow screws fixation instead. Rehabili-tation was delayed until two weeks postoperatively. The function of the knee was satisfactory in the former patient after three months, who could extend the knee in a normal range, without pain or locking. The same effect was gained in the latter patient after four months. Conclu-sion For acute tibial avulsion fracture of PCL with larger and intact fragment without osteoporosis, arthroscopic restoration and fixation with double titanium plate TightRope offers the opportunity to achieve anatomic reconstruction and rigid fixation for early rehabilitation in adult patients.

Objective To explore the indications of cervical artificial disc replacement (ADR) based on radiographic evaluation and different anterior decompression methods. Methods From January 2008 to July 2009, 175 patients with cervical spondylosis or disc herniation who underwent anterior decompression were involved in this study. Patients were distributed to different operative groups based on the preoperative radiographic evaluation. One hundred and forty-five cases were treated with fusion operation, and the others received ADR. Operative methods were as follows: 1) Anterior cervical discectomy and fusion (ACDF); 2)Anterior cervical discectomy and subtotal vertebrectomy; 3) Anterior subtotal vertebreetomy and fusion; 4)ProDisc-C ADR. The patients with single-level of cervical spondylotic myelopathy were divided into ACDF and ADR groups according to different operative methods. Clinical outcomes of two groups were evaluated by Japanese Orthopaedic Association (JOA) score. The range of motion (ROM) of the segment was recorded in ADR group at the 1st month, 3rd month, 6th month and 12th month postoperatively. Results The indication of ADR was cervical spondylosis with slight disc calcification or small vertebral posterior osteophytes. Under this condition, decompression could be obtained thorough intervertebral space and ADR be implanted. If cervical spondylosis was associated with vertebral posterior huge osteophytes, serious intervertebral narrow or fusion, serious disc calcification ,ossification of the posterior longitudinal ligament and extensive cervical spinal stenosis, subtotal vertebrectomy was necessary. The mean improvement rates of ACDF and ADR were 66.05% and 67.13%. There was no difference between two groups (P ＞ 0.05). No difference of ROM was found before and after surgery in ADR group (P ＞0.05). Conclusion Only decompression can be achieved thorough through the intervertebral space, and ADR is suitable for cervical spondylosis. ACDF and ADR have similar outcomes in treatment of single-level of cervical spondylotic myelopathy. But ADR has the advantage of maintaining ROM of the operative segment.

Objective To investigate the changes in the expression of GABAAα1, receptors in medial prefrontal cortex (mPFC) in a rat model of neuropathic pain. Methods Nine male Wistar rats weighing 200-210 g were randomly divided into 3 groups ( n = 3 each): control group (group C) , sham operation group (group S) and neuropathic pain group (group P). Neuropathic pain was induced by chronic constrictive injury. The right sciatic nerve was exposed and 4 loose ligatures were placed on the sciatic nerve at 1 mm intervals with 3-0 chromic catgut. In group S, the right sciatic nerve was exposed but not ligated. The thermal and mechanical pain threshold was measured at 1 d before and 1,4,7, 10 and 14 d after operation. The animals were then sacrificed and the mPFC was removed. The expression of GABAAα1, receptors in mPFC was determined by Western blot. Results Compared with C and S groups, thermal and mechanical pain threshold were significantly decreased and the expression of GABAAα1, receptors was up-regulated in group P ( P ＜ 0.01) . There was no significant difference was in the thermal and mechanical pain threshold and expression of GABAAα1 receptors between C and S groups (P ＞ 0.05). Conclusion Up-regulation of GABAAα1 receptor expression in mPFC may be involved in the development and maintenance of neuropathic pain in rats.

·AIM: To study the effect of calcium dobesilate combined with panretinal photocoagulation on severe non-proliferative diabetic retinopathy patients (NPDR). ·METHODS:A total of 92 patients (184 eyes) with severe NPDR were collected in our hospital from December 2014 to April 2017, and divided into laser group and combined treatment group by random number table method. The laser group was treated with panretinal laser photocoagulation, and the combined treatment group received calcium dobesilate combined with retinal laser photocoagulation. The effect of the two groups was compared on the retinal microcirculation parameters. · RESULTS: Seven weeks after treatment, treatment effective rate in combined treatment group was higher than that in laser group (P<0.01). Fundus examination parameter such as Ops OS2, subfoveal choroid thickness (SFCT) in combined treatment group were higher than those in laser group (P<0.01). Retinal microcirculation parameters such as PSV, MV in combined treatment group were higher than the level of the laser group,RI,PI levels were lower than those in laser group (P<0.01). · CONCLUSION: Calcium dobesilate combines with panretinal photocoagulation in severe NPDR patients can effectively improve the overall effect and optimize the fundus structure and retinal microcirculation.

Objective:To evaluate the clinical outcome of botulinum A toxin(BTX-A)injection into external sphincter combined with oral baclofen in treatment of detrusor-external sphincter dyssynergia(DESD)after spinal cord injury(SCI). Methods:A total of 38 urodynamic examination-confirmed DESD patients,male 31 and female 7,with an average age of (36.5?17.8)years old,were included in this study.200 U of BTX-A toxin was dissolved in 8 ml of normal saline and the solution was injected at 8 different sites(1 ml per site)of the external sphincter via a 5F flexible cystoscopic needle.On the second day,9 patients(BTX-A+baclofen group)were randomly selected for baclofen oral administration,3/d for 3 months; the other 26 patients were taken as control.Urodynamic examination was repeated in all patients 4 weeks later;the voiding diary and urodynamic outcomes were compared before and after treatment.The adverse and toxic effects were observed in the patients who were followed up for 2-9 months.Results:One month after treatment the voiding and storing functions of bladder were improved to different degrees,with the mean maximum uroflow rate(Qmax),the mean urine volume,the mean maximal cystometric capacity and the bladder compliance increased significantly and the mean postvoid residual urine volume and the mean maximal voiding pressure decreased significantly(all P

Objective To investigate the management of ankle fracture with surgery and postoperative rehabilitation.Methods The data of 39 inpatients with ankle fracture from 2001 to 2005 were analyzed retrospectively. All patients were treated surgically with open reduction and internal fixation (ORIF) except one medial ankle fracture with closed reduction. All patients were encouraged to perform active and passive range of motion exercises of ankle and the involved limb on the 2nd day after surgery, and partial weight-bearing was allowed at 4th week after surgery.Results No patients had wound-healing problems and deep venous thrombosis, no significant calf muscle atrophy exist at discharging. 29 patients showed excellent ankle joint function and normal gait when the internal fixation was removed at an average 17.9 postoperative months.Conclusion The surgery combined with early rehabilitation used for ankle fracture can improve the recovery of ankle function.

OBJECTIVETo study the validity of single plane Simpson's method with conventional X-ray ventriculography for estimation of right ventricular (RV) volume.

METHODSFifteen human RV casts were obtained from 15 subjects who died from non-cardiac causes within 24 hours after death. These casts were photographed respectively and their volumes were calculated by using the single plane Simpson's method based on a new half-circle model. The actual RV cast volumes were determined by water displacement method.

RESULTSThe actual RV volume was (64.23 +/- 24.51) ml and the calculated volume was (58.04 +/- 24.45) ml. The calculated RV volume underestimated the actual volume by (6.19 +/- 12.38) ml, but there was no significant difference between the actual and the calculated RV volume (P > 0.05). There was a significant correlation between the actual cast volume and the calculated volume (r = 0.983, P < 0.01). The regression equation was: RV actual volume = 1.074 x (RV calculated volume).

CONCLUSIONRV volume calculated by single plane Simpson's method with conventional X-ray ventriculography is accurate and deserves further study.

OBJECTIVETo analyze the level of the oxytocin (OT) and the expression of oxytocin receptor (OTR) in males with idiopathic infertility.

METHODSSixty-five infertile males aged 20 -45 years were divided according to their semen parameters into an idiopathic oligozoospermia group (OG, n = 20), an idiopathic asthenozoospermia group (AG, n = 25), and an idiopathic oligoasthenozoospermia group (OAG, n = 20). Another twenty 20-45 years old healthy male volunteers with a natural childbearing history were included in the control group (CG). All the subjects were detected for the contents of luteinizing hormone (LH), follicle stimulating hormone (FSH) , testosterone (T) and OT, and analyzed for the expression of OTR by sequencing the functional region of the OTR promoter (OTRP), OTR-mRNA, and OTR-COOH terminus. The gene sequences were compared using DNASTAR-MegAlign, Western blot values changed into enumeration data, and all the data analyzed by one-way ANOVA and Dunnette's multiple range t-test.

RESULTSA significantly lower content of OT was observed in CG ( [79.30 +/- 3.83] pg/ml) than in OG ([118.53 +/- 7.69] pg/ml, AG ([108.81 +/- 5.66] pg/ml) and OAG ([103.71 +/- 4.54] pg/ml) (F(0.05/2[2,82]) = 8.29, P < 0.01). The content of LH was significantly lower in AG ([4.26 +/- 0.31] IU/L) and OAG ([4.55 +/- 0.40] IU/L) than in OG ([6.77 +/- 0.57] IU/L) and CG ([7.19 +/- 0.50] IU/L) (F(0.05/2 [2,82]) = 11.64, P < 0.01), and so was the content of FSH in AG ( [5.02 + 0.39] IU/L) than in CG ([8.91 +/- 0.91] IU/L), OG ([11.86 +/- 1.76] IU/L) and OAG ([8.82 +/- 1.03] IU/L) (F(0.05/[2,82]) = 7.22, P < 0.01). There were no significant differences in the T content among the four groups (F(0.05/2[2,82] = 0.42, P = 0.739). No evident gene mutation was found in OTRP and OTR-mRNA gene sequencing. Human OTRs in the lymphocytes were monomers and oligomers, mostly tetramers and hexamers. There were obviously more monomers in AG (0.41 +/- 0.03) and OAG (0.13 +/- 0.01) than in OG (0.05 +/- 0.004) and CG (0.05 +/- 0.003) (F(0.05/2[2,82]) = 115.50, P < 0.01), while the number of oligomers was markedly decreased in 20% of the cases in AG.

CONCLUSIONSignificant differences in the content of OT and expression of OTR between fertile and infertile men suggested an association of OT with male infertility. The decreased expression of OTR oligomers and increased expression of monomers may be related to idiopathic asthenozoospermia, which has provided a new insight into the pathogenesis and treatment of male infertility.
