Objective To investigates the possible methodes for adult human Schwann cell culture and proliferation with F-12 medium which could be used on human body. Methods Nineteen human peripheral nerves were used in this study, 12 of them were cultured under F-12 medium and the other 7 nerves under standerd medium. The medium were changed every 2 days, and the nerve tissues were transfered to another plate when there were too many cells, after 6-8 times of transferring, most of the cells were Schwann cells and the nerve tissues were digested using none cell toxic collagenas. The cells were counted and evaluated the survival rate with Live-Dead kit S-100 protein immunostaining was used to assesse the Schwann cell purity. Results The survival rate of the cells were 85.54% and 86.93% , and the Schwann cell purity were 82.64% and 86.37% respectively, there were no difference between the two different medium, but we got more cells from F-12 medium than Standard medium, which was 14.2?10~7 and 5.9?10 respectively. Conclusion The F-12 medium could be used for human Schwann cell culture, meanwhile it had possible function on Schwann cell proliferation.

AIM: To analyze the difference of endonuclease domain containing 1 (ENDOD1) expression be-tween benign prostatic hyperplasia ( BPH ) tissues and prostate cancer ( PCa ) tissues and to investigate the effect of ENDOD1 on the biological function of human prostate cancer cells .METHODS: The BPH samples ( n=20 ) and PCa samples (n=21) were processed and analyzed according to the instruction of immunohistochemical (IHC) staining.The mRNA and protein levels of ENDOD 1 in the normal prostate epithelial cells and prostate cancer cells were evaluated by RT -qPCR and Western blot , respectively .The recombinant plasmids pCMV-N-Flag-ENDOD1 was constructed and was trans-fected into the human prostate cancer cells .The proliferation , apoptosis , migration and invasion abilities of the prostate cancer cells were evaluated by MTT assay , flow cytometry, Transwell migration and Matrigel invasion assays , respectively. RESULTS:The analysis of variance of the immunoreactivity score showed that PCa tissues with high Gleason score dis -played significantly lower ENDOD1expression than that with low Gleason score and BPH (P<0.05).The expression of ENDOD1 at mRNA and protein levels in PC3 cells and DU145 cells was significantly lower than that in the LNCap cells (P<0.05).The proliferation of DU145 transfected with ENDOD1 was inhibited.The flow cytometry indicated that ENDOD1 over-expression in the DU145 cells resulted in a notable increase in G0/G1 phase arrest (P<0.05), but the ap-optotic rates showed no statistical difference .The results of Transwell assay showed that migration and invasion abilities of the cells were also inhibited after transfection with over-expressing ENDOD1 plasmid (P<0.05).CONCLUSION: The expression of ENDOD1 significantly decreased in prostate cancer with high Gleaon score .Meanwhile, the ENDOD1 is spe-cifically down-regulated in androgen independent prostate cancer (AIPC) cell lines.Over-expression of ENDOD1 remark-ably inhibits the proliferation , migration and invasion abilities of AIPC .

ObjectiveTo evaluate the clinical efficacy of bladder hydrodistention and intravesical sodium hyaluronate in the treatment of interstitial cystitis (IC).Methods Twenty-one IC patients received intravesical sodium hyaluronate therapy under combined blockage or intravenous anesthesia.Bladders were perfused with normal saline under 100 cm H2O perfusion pressure and expanded for 10 min,the bladders were then injected through a catheter with 40 mg/50 ml sodium hyaluronate which was released after 1 h.Intravesical perfusion was applied once every week four to six times in a course of treatment.Results The average bladder capacity was extended from 191.6 ± 88.7 ml before expansion to 425.3 ± 79.8 ml after bladder expansion ( P =0.000).The extension was done under anesthesia.There were two suspected bladder ruptures after starting the bladder expansion at 6.5 min and 7.2 min.There was significant gross hematuria in 19 cases,10 min after bladder expansion.After treatment,the catheters were removed 24 h after manipulation in 17 patients; the catheters were removed 72 h after manipulation in two cases with hematuria;the catheters were removed four days after manipulation in the two cases of suspected bladder rupture.Pain was significantly reduced after the catheters were removed and the maximum urinary output increased slightly.The day before the second injection of sodium hyaluronate,the urinary frequency decreased significantly than before start of treatment (32.8 vs 18.5 times/24 h).The maximum urinary output increased significantly compared with the output before treatment (86.7 vs 151.9 ml).Pain was reduced significantly after treatment (8.7 vs 3.0).The O'Leary-Sant IC score and the QOL were significantly improved (30.0 vs 17.0,5.9 vs 2.4,respectively) (P =0.000).After the third treatment,the symptoms continued to improve.The treatment results were best in the fifth week at the time of the sixth injection of sodium hyaluronate.Symptoms rebounded at six months.However compared with that before treatment,the difference was still statistically significant ( P =0.000).ConclusionsBladder hydrodistention under anesthesia for severe intractable IC patients produces immediate effectiveness.Sodium hyaluronic infusion can alleviate urinary frequency and pain,and the effectiveness and duration of treatment are positively correlated.

To survey the serum uric acid (SUA) levels and associated risk factors of hyperuricemia among youth and middle-aged residents in Guangzhou.A total of 1420 subjects,aged from 20 to 60 years,receiving health check-up at our hospital in 2010 were enrolled.The total prevalence of hyperuricemia was 22.04％,32.01％ in males and 14.07％ in females.The average SUA was (388 ±78) μmol/L in males and (288 ± 63) μ mol/L in females.The prevalence of hyperuricemia in males was 30.11％ before 40 years of age and 33.81％ between 40 and 60 years of age.The average level of SUA in males was significantly higher than that of females.logistic regression analysis showed that BUN,body mass index (BMI) and hypertriglyceridemia were the independent risk factors of disease while HDL-C and gender (females) the protective factors.

OBJECTIVETo observe long-term functional recovery after contralateral C7 transfer.

METHODSFrom August 1986 to July 2000, 224 patients with brachial plexus avulsion injuries were treated with contralateral C7 transfer in our department. Thirty-two patients were followed up for over 2 years for evaluation of the following items: 1 influence on healthy limb function; 2 sensory and motor recovery of the recipient nerves in the affected limb; and 3 coordination between the healthy and affected limbs.

RESULTSThere was no impairment of healthy limb function. Functional recovery of the recipient area reached > or =M3 in 8 patients (8/10, 80%) after musculocutaneous nerve neurotization, > or =M3 in 4 patients (4/6, 66%) after radial nerve neurotization, > or = M3 in 7 patients (7/14, 50%) and > or = M3 in 12 patients (85.7%) after median nerve neurotization, and > or = M3 in 1 patients (1/2, 50%) after thoracodorsal nerve neurotization. Synchronic contraction of the affected limb with the healthy limb occurred within 2-3 years in 12 patients, within 5 years in 13 patients, and over 5 years in 7 patients.

CONCLUSIONContralateral C7 transfer is an ideal procedure for the treatment of brachial plexus root avulsion injury. Selection of the whole root or the posterior division as neurotizer and a staged operation are the major factors influencing treatment outcome.

[Abstrict]Objective To explore the key points and clinical value of combined direct and indirect extracranial-in?tracranial (EC-IC) bypass in patients with adult moyamoya disease. Methods Retrospective analysis of combined revas?cularization surgery in 25 adult patients with moyamoya disease. The frontal branch and parietal branch of the superficial temporal artery (STA) were dissected. Combined revascularization surgery consisted of direct (anastomosis between the su?perficial temporal artery and cortical branch of the middle cerebral artery) and indirect (encephalodurogaleosynan-giosis EDAS) surgeries. Clinical status was evaluated using the modified Rankin Scale and NIHSS score at 1 day before, 1 week and 3 months after surgery. Results Thirty lateralities were successfully performed on 25 patients. Postoperative angiogra?phy or CTA and cranial computer tomography perfusion imaging(CTP) were conducted to examine the patency of the di?rect anastomosis and cerebral blood flow in 23 patientswithin 1 weeks after surgery . The results showed that the anasto?motic vascular patency was excellent and the cerebral blood flow increased in parallel to the relief of the patients’s isch?emic symptoms. The median mRS scores were 3 (1,3) before surgery, 2 (1,3) 1 week and 1 (0,3) 1 month after surgery.The median mRS scores were significantly improved (Z=15.14, P<0.01). The median NIHSS scores was 5 (4,8) preopera?tively and 4(2,7) postoperation 1 week and 3(1,4) 3 months. The median NIHSS scores were also significantly improved (Z=11.36, P<0.01). Unfortunately, two patients had complication and left hemiparesis. One patient complicated with con?tralateral hemisphere infarction and the another one complicated with ipsilateral hemispheric hemorrhage after operation. Conclusions Combined revascularization surgery may result in satisfying improvement in clinical, angiographic, and he?modynamic states and prevention of recurrent stroke. The stabilized hemodynamic is the key point in peroperative period for moyamoya patients.

Objective To evaluate the mid-term clinical and radiographic results of artificial disc replacement (ADR) for discogenic low back pain.Methods From July 2004 to July 2007,21 patients with discogenic low back pain,aged from 26 to 67 years,underwent lumbar ADR with the Charité Ⅲ artificial disc at 22 levels and Activ L prosthesis at 2 levels:L4-5 5 cases,L5S1 13 cases,L4-5 and L5S1 3 cases.The diagnosis was proved by discography in all the patients.The clinical and radiographic results were evaluated and compared between pre-,post-operation and finial follow-up.Results All patients were followed up for 4to 7 years (average,5.1 years).There were statistical differences between pre-operation and final follow-up in Oswestry disability index and Visual Analogue Scale for back pain and leg pain.All the prostheses were mobile without dislocation,breakage,subsidence or spontaneous fusion,only a slight scoliosis was noted in one patient.At the ADR levels,the anterior and posterior intervertebral height increased averagely 6.3 mm and 1.9 mm respectively,the lordosis increased 2.9°,and the mean range of motion (ROM) was 4.6°.At the adjacent level proximal to ADR,the intervertebral height and lordosis decreased slightly,and the ROM decreased 2.5°.The total lumbar lordosis increased 7.8°,and the total lumbar ROM increased 2.4°.According to MRI and CT scans,the degeneration of proximal adjacent disc and facet were not evident,however the degeneration of facets at the ADR levels was evident.Conclusion The 5 years results of ADR for discogenic low back pain were satisfactory,with preserved motion at the ADR level,and the degeneration of adjacent level was not evident.However,there was obvious degeneration in facet joints of the ADR level.

Objective:To investigate the efficacy of repetitive transcranial magnetic stimulation (rTMS) combined with oral paroxetine in the treatment of older adult patients with severe depression and its effects on the scores of the Hamilton Rating Scale for Depression (HAMD), the Mini-Mental State Examination (MMSE), and Activities of Daily Living (ADL).Methods:A total of 192 older adult patients with severe depression who received treatment in Shaoxing 7 th People's Hospital from January 2018 to December 2019 were included in this study. They were randomly assigned to receive either oral paroxetine (control group, n = 96) or rTMS + oral paroxetine (observation group, n = 96). All patients received 1 month of treatment. Clinical efficacy was compared between the two groups. HAMD, MMSE, and ADL scores pre- and post-treatment and the incidence of adverse events during the treatment were compared between the two groups. Results:Total response rate was significantly higher in the observation group than in the control group [96.88% (93/96) vs. 89.58% (86/96), χ2 = 4.04, P < 0.05]. HAMD scores post-treatment were significantly lower in the observation group than in the control group [(6.43 ± 2.33) points vs. (11.32 ± 2.02) points, t = 15.53, P < 0.05]. MMSE and ADL scores post-treatment in the observation group were (29.13 ± 3.01) points and (71.52 ± 5.32) points, respectively, which were significantly higher than those in the control group [(24.65 ± 2.79) points, (69.65 ± 5.17) points, t = 10.69, 2.47, P < 0.05]. There was no significant difference in the incidence of adverse events between the two groups ( P > 0.05). Conclusion:The combined therapy of rTMS and oral paroxetine is highly effective on severe depression in older adult patients. It can improve cognitive function and the activities of life living.
