ABSTRACT
Objective@#To evaluate the clinical efficacy of percutaneous tibial nerve electrical stimulation in the treatment of chronic pelvic pain syndrome.@*Methods@#The clinical data of 28 patients with chronic pelvic pain syndrome from January to November 2018 in Dalian Third People′s Hospital were retrospectively analyzed. The patients were treated with percutaneous tibial nerve stimulation. The number of urination in 24 h, number of nocturnal urination, urine volume per urination, quality of life (QOL) score and digital pain intensity score before treatment and after treatment were compared; the patients were followed up for 3 months, and the recurrence and adverse reaction were observed.@*Results@#Compared with those before treatment, the number of urination in 24 h and number of nocturnal urination after treatment were significantly lower: (11.6 ± 6.4) times vs. (20.6 ± 7.8) times and (2.5 ± 1.2) times vs. (5.2 ± 2.6) times, and the urine volume per urination increased significantly: (181.2 ± 65.6) ml vs. (125.4 ± 58.2) ml, the QOL score and digital pain intensity score decreased significantly: (2.6 ± 1.4) scores vs. (5.1 ± 0.8) scores and (2.9 ± 1.3) scores vs. (6.9 ± 1.4) scores, and there were statistical differences (P<0.05). During the follow-up period, none of the patients had recurrent symptoms and obvious adverse reaction.@*Conclusions@#Percutaneous tibial nerve stimulation is an effective way to treat chronic pelvic pain syndrome.
ABSTRACT
Objective To compare the clinical efficacy of different margins in nephron-sparing operation for patients with small renal cell carcinoma. Methods From September 2008 to April 2013, a total of 64 patients with local renal cell carcinoma (T1a period) and treated with nephron-sparing operation were selected, and the clinic data were analyzed. According to cutting edge size gotten from the surgery, the patients were divided in to A group (cutting edge 1-5 mm group, 30 cases) and B group (cutting edge 6-10 mm group, 34 cases). The operation condition and recurrence rate and survival rate of two groups were compared. Results The operative time in A group was significantly shorter than that in B group:(130.1 ± 24.0) min vs. (152.3 ± 28.0) min, P0.05). The 3-year recurrence rate and 3-year survival rate in two groups had no significant differences (P>0.05). Conclusions The clinical efficacy of different margins in nephron-sparing operation for small renal cell carcinoma is similar. But 1- 5 mm cutting edge size nephron-sparing operation has less complications, and the recurrence rate and survival rate does not increase. It is worthy of spread .

Objective ToanalyzethedistributionanddrugresistancesituationofKlebsiellapneumoniae(KPN)isolatedfromour hospital during 2014 .Methods The drug susceptibility test was carried out by the Siemens fully automatic bacterial identification /drug susceptibility test analyzer .The drug susceptibility test results were judged according to the (CLSI) M100‐S22 document (2012) .Results A total of 291 strains of KPN were detected from 8 486 submitted specimens ,in which 20 strains were multi‐drug resistant Klebsiella pneumoniae(MDR‐KPN)isolates were 213 strains ,48 strains were extended‐spectrum beta‐lactamases producing Klebsiella pneumoniae (ESBLs‐KPN) and 10 strains were carbapenem‐resistant Klebsiella pneumoniae(CR‐KPN) .The KPN detec‐tion rate had statistical difference among different specimens (P= 0 .000) .The constituent ratio of KPN isolation in the sputum specimen was highest(P=0 .000) .The KPN detection rate had statistical difference among different departments (P=0 .000) ,the constituent ratio of KPN isolation in the respiration department was highest (P=0 .000) .The resistance and sensitivity of KPN to different antibacterial drugs had statistical difference(P=0 .000) ,carbapenems had the lowest resistance rate .Conclusion KPN has relatively low resistance rate to commonly used antibacterial drugs ,its multi‐drug resistant strains are in the higher level ,which should arouse clinic and hospital infection management department must to pay attention to and adopt corresponding supervision measures .
ABSTRACT
Objective To investigate the expression of pancreatic thioredoxin-1 (TRX-1) in rats with acute necrotizing pancreatitis (ANP) and the effect of pretreatment of melatonin on its expression. Methods Male Spraque-Dawley rats (n = 12) were randomly divided to ANP group, melatonin group, control group with 24 rats in each group. The rats in ANP group received three intraperitoneal injections of 25 ml/kg body weight 6% L-arginine at an interval of 1 h to induce ANP. The rats in melatonin group received intraperitoneal injections of 25 ml/kg body weight 6% melatonin 30 min before ANP induction; rats in ANP group and control group received intraperitoneal injections of same amount of saline. Rats were sacrificed at 6 h, 12 h and 24 h after ANP induction. The serum level of amylase was measured and the pathological evaluation of pancreatic tissues was performed. The concentrations of malondialdehyde (MDA) and myeloperoxidase (MPO) in pancreatic tissues were measured. The expressions of TRX-1 protein were detected by immunohistochemistry and the expressions of TRX-1 mRNA in pancreatic tissues were determined by RT-PCR.Results In ANP group, serum level of amylase, MDA, MPO, TRX-1 mRNA and TRX-1 protein in pancreatic tissues were (3 012 ±1 425) U/L, (4.13 ± 1. 85)nmol/mg prot,(7.45 ± 1.26)nmol/mg prot, 0.68 ±0. 18, 66.8 ±8. 1, while they were (1 835±499)U/L, (3.03 ±2.12) nmol/mg prot, (5. 32 ± 1.06) nmol/mg prot, 0.50±0.09, 80. 29 ±8. 14, respectively in melatonin group, the values in melatonin group were significantly lower thanthose in ANP group (P < 0.05). The peak value of TRX-1 mRNA and TRX-1 protwein expressions shifted from 12 h after ANP induction in ANP group to 6 h after ANP induction in melatonin group. Conclusions The expression of pancreatic TRX-1 protein and TRX-1 mRNA in rats with ANP was significantly increased. Melatonin pretreatment could promote pancreatic tissues to express TRX-1 protein and TRX-1 mRNA, and may be protective for pancreatic tissues damages.
