Objective To investigate the effect of hyperbaric oxygen(HBO)on p38 MAPK signal pathway in neuropathic pain,and explore its mechanism. Methods The experiment was divided into two parts with thirty SD rats in each part. Each part was then randomly divided into 3 groups:sham operation group(S group),chronic constriction group(CCI group)and hyperbaric oxygen group(HBO group),with 10 rats in each group. Part one:Pain?related behavior were detected on 3 day,7 day,14 day,28 day after operation. Phosphorylative p38 was detected by Western blot method and the P2X4 receptor was detected by immunohistochemistry method on the 28th day. Part two:All the rats were treated with SB203580. Pain?related behavior were detected on 3 day,7 day,14 day,28 day after operation. P2X4 receptor was detected by immunohistochem?istry method on the 28th day. Results CCI and HBO groups were significantly lower than S group in pain?related behaviors(P<0.05). CCI group was significantly lower than that in HBO group(P<0.05). The content of phosphorylative p38 and P2X4 receptor in CCI and HBO group were increased(P<0.05),and the expression of phosphorylative p38 and P2X4 in CCI group was significantly increased than that in HBO group (P<0.05). When p38 MAPK was inhibited,pain?related behavior in HBO and CCI group increased significantly than the pain?related behavior of HBO and CCI group in Part 1(P<0.05). But the difference between group CCI and HBO was not significant(P>0.05). Though the expression of P2X4 receptor in CCI group and HBO group was significantly higher than that in S group(P<0.05),the difference between group CCI and HBO was not significant(P>0.05). Conclusion Hyperbaric oxygen therapy can affect the expression of p38 MAPK through P2X4 receptor in rats of neuropathic pain.

Objective To investigate whether hyperbaric oxygen(HBO)affected neuropathic pain through autophagy and verify the HBO effect. Methods A total of 60 male SD rats were selected for the study and randomly divided into 4 groups:control group(C group),sham operation group (S group),chronic constriction group(CCI group)and hyperbaric oxygen group(HBO group). LC3Ⅱand P62 were determined by Western blot method and the autophagy was detected by electron microscopy on the 7th day. Results CCI and HBO groups were significantly higher than C and S group in Western blot(P<0.05). There was no difference between group C and group S(P>0.05). The expression of LC3Ⅱin HBO group was significantly higher than that in CCI group(P<0.05). And the expression of P62 in CCI group was significantly higher than that in HBO group(P<0.05). The autophagy in CCI and HBO group were significantly increased comparing to the C and S groups(P<0.05). However,the difference be?tween group C and S was not significant(P>0.05). Conclusion Hyperbaric oxygen therapy can induce autophagy for anti?neuropathic pain.

Objective To analyze the allele frequencies of 5 short tandem repeat(STR)loci(D12S313,D12S304,D12S1640,D12S1708 and D12S1583)on chromosome 12 among Kashin-Beck disease(KBD)patients and the control population living in the area suffered from KBD.Methods Fifty KBD patient8 and 50 non-KBD patients were chosen in endemic afea of Shaanxi Province,5 STR loci on chromosome 12 were genotyped by the technology of polymerase chain reacfion(PCR)and capillary electmphoresis.The pelymorphisms of STR in these popIllations were analyzed.The allele and genotype frequencies of each STR in the corresponding groups were caleulated and compared. Results In KBD group,the 5 STR loci had 8,6,7,5 and 11 types ofalleles and 17,11,15,8 and 28 genotypes, respectively;while in the control group,the number of aUele types of 5 STR loci were 6,8,6,4 and 10,the number of genotype of those loci were 13,21,14,8 and 23,respectively The allele frequence of D12S304 locus was statiBtically significant between KBD patients and controls(P<0.05),especially for the 319 bp allele(P<0.006 25). Conclusion There is an association between D12S304 locus and KBD.The 319 bp allele might play the key role.

Objective To establish a self-made chiral column for enantiomeric separation of salbutamol. Methods We used different concentrations of acid,alkali additives in the polar phase flow for enantiomers separation of salbutamol by using 3, 4-dichlorophenyl isocyanate vancomycin chiral column, and discussed the chiral recognition mechanism. Results The ratio of acid to alkali additive in the mobile phase was 0.01%:0.01% (V/V), the flow rate was 1ml/min, the column temperature was 25℃, and the best separation of enantiomers of salbutamol was obtained,the selective factor was 1.16, the separation degree reached 1.41. Conclusion Self-made 3, 4-two chlorophenyl isocyanate vancomycin chiral column is effective for salbutamol separation, and it can be as a reference for developing other similar chiral stationary phase.

Objective To evaluate the clinical feasibility of performing the placement of drainage tube via transnasal route in treating mediastinal anastomotic fistula after surgery of esophageal cancer.Methods A total of 6 patients with mediastinal anastomotic fistula after surgery of esophageal cancer,who were admitted to authors' hospital during the period from August 2015 to January 2016,were included in this study.The diagnosis was confirmed by esophageal radiography and thoracic CT scan in all the 6 patients.Under X-ray monitoring,the drainage tube was inserted into the cavity of mediastinal fistula with the help of a guide wire guidance,and continuous negative pressure suction was adopted.The jejunum nutrition tube was inserted via the same nostril if feeding tube was not placed.Results Successful placement of fistula drainage tube and jejunum nutrition tube was achieved in all the 6 patients.In one patient the fistula drainage tube had to be re-placed as the drainage tube was obstructed five days after initial placement.Under X-ray monitoring the mean time used for the drainage tube placement was 33 min (range of 23-48 min).The procedure was well tolerated by all the 6 patients,and no procedure-related complications occurred.After continuous negative pressure suction that lasted for 6-40 days (mean of 23 days) the fistulae healed.Conclusion For the treatment of mediastinal anastomotic fistula after surgery of esophageal cancer,the placement of fistula drainage tube under X-ray monitoring is simple,safe and effective.(J Intervent Radiol,2017,26:250-252)

Objective To analyze the efficacy and safety of suprapubic arc sling (SPARC) and transobturater vaginal tape (TOT) for female stress urinary incontinence (SUI). Methods A retrospective study was conducted on 275 women ( 139 in TOT group and 136 in SPARC group) in our institute from September 2008 to January 2011.We had compared the complications of the two groups.All the patient's ICI-Q-SF scores and PISQ-12 scores were collected.We compared the pre- and post-operative Qmax and PVR to find out if SPARC or TOT tap cause bladder outlet obstruction (BOO). Results The operative time was 25.1 ± 3.3 min for TOT and 34.8 ± 5.6 min for SPARC.There was statistical difference between the two groups in the aspects of operative time (P =0.00).The improvements of average symptom and QOL scores in patients undergoing TOT and SPARC were statistically significant (P =0.00).The improvements of the PISQ-12 scores in the two groups were statistically significant (P ＜0.05 ) as well.There was no significant difference (P ＞ 0.05 ) in the total cure rate of TOT and SPARC.The complications post SPARC and TOT were low.In the TOT group,the Qmax changed from 30.2 ± 8.7 ml/s per-operatively to 24.9 ± 8.6 ml/s post-operatively in a week.PVR changed from 1.6 ± 4.2 ml pre-operatively to 3.2 ± 6.5 ml post-operatively in a week.In the SPARC group,the Qmax changed from 31.7 ±9.4 ml/s pre-operatively to 26.9 ± 8.9 ml/s post-operatively in a week.PVR changed from 1.4 ± 3.7 ml pre-operatively to 3.5 ± 6.3 ml postoperatively in a week.All the changes were significant ( P ＜ 0.05 ).And in the SPARC group,the Qmax changed from 31.2 ± 10.0 ml/s pre-operatively to 26.2 ± 9.1 ml/s post-operatively; the PVR changed from 1.8 ± 3.2 ml pre-operatively to 4.7 ± 8.8 ml post-operatively (P ＜ 0.05). Conclusions Both the TOT sling and the SPARC sling have high cure rates for SUI.But the retropubic sling may lead to BOO and other complications,so the transobturate sling is a better treatment option for SUI.

Objective To assess the safety and efficacy of the transohturator tape (TOT) for surgical treatment of female stress urinary incontinence (SUI). Methods Clinical data of 206 TOT procedures for female urinary incontinence from Jan 2007 to Dec 2009 was retrospectively analyzed.Thirty-one women were identified as having mixed stress urinary incontinence.The mean age was 54.29 years(range,32-81 years),themean disease coursewas 10.31 years (range,1-40 years),and the mean follow-up time was 17.3 months (range,3-39 months).Therapeutic effects were assessed by Grouts-Blaivas outcome score.The results of the operation,complications and changes of urodynarnics were observed. Results The TOT operations were conducted under local anesthesia.The mean operative time was 23.9 min (range,16-35 min),Mean blood loss was 17.8 ml(range,15-30 ml).Short-term complications were as follows:thigh pain 14.08%,dysuria 5.83%,urinary posture change 0.97% and urinary retention 0.49%.The long-term complication rate was 0.97%,including vaginal wall defect and tape exposure in one case:the burr of tape exposure and sex life influence in one case.Long-term symptoms disappeared completely in 202 cases.The cure rate was 98.06%,and the rate of satisfaction was 100%. Conclusions Our results demonstrate that TOT procedure is a minimally invasive,safe and effective surgical treatment for stress urinary incontinence.
