Objective To explore the expression and clinical significance of survivin protein and proliferation cell nuclear antigen(PCNA) in human nasopharyngeal carcinoma (NPC). Methods The expression of survivin protein and PCNA was detected by SP immunohistochemical technique in 96 cases of NPC tissues. Results The positive rate of survivin expression was 75.0% in PNC. Labeling idex(LI) of PCNA in survine positive NPC was higher than that in survivin negative NPC. The positive rate of survivin expression in NPC with neck lymph node metastasis was higher than that in NPC without neck lymph node metastasis. The positive rate of survivin expression in NPC patients with less than 5-year survival rate was higher than that in NPC patients with over 5-year survival rate. Conclusion NPC had survivin expression, and survivin expression in NPC was positive related with PCNA expression. The survivin protein might promote the neck lymph node metastasis of NPC cells. The prognosis of the patients with survivin positive NPC was worse.

Objective To investigate the antimicrobial resistance of clinical isolates in Tongling People′s Hospital during 2013. Methods A total of 2 281 nonduplicate clinical isolates were collected.Kirby-Bauer disc diffusion method was employed to study the antimicrobial susceptibility.The data were analyzed with WHONET 5.6 software according to CLSI 2012 breakpoints. Results The top 5 most frequently isolated microorganisms were E.coli (479,21.0%),K.pneumoniae (360,15.8%),A. baumannii (271,11.9%),P .aeruginosa (240,10.5%),S.aureus (171,7.5%).Gram negative and gram positive microorganisms accounted for 76.5% and 23.5%,respectively.The prevalence of methicillin-resistant strains in S.aureus (MRSA)and coagulase negative Staphylococcus (MRCNS)was 38.6% and 73.1%,respectively.The resistance rates of MR strains to beta-lactams and other antimicrobial agents were much higher than those of MS strains.No staphylococcal strain was found resistant to vancomycin or teicoplanin.E.faecalis showed relatively lower resistance to penicillin,ampicillin and nitrofurantoin.E.faecium strains were more resistant than E.faecalis to most of the antibiotics tested.Approximately 50.5% of E.coli and 44.5% of Klebsiella isolates produced extended-spectrum beta-lactamases (ESBLs).The ESBLs-respectively.And 29.8% and 23.4% of the P .aeruginosa strains were resistant to imipenem and meropenem.Nearly all (94.0%)P .aeruginosa isolates were susceptible to amikacin.Conclusions There appears a trend of increasing resistance in the clinical bacterial isolates in this hospital,especially the carbapenem-resistant Enterobacteriaceae,which is of great concern.It is mandatory to take effective antibiotic policy and infection control measures.

Objective:To investigate the effect of dexmedetomidine (DEX) on reducing urethral stimulation in patients undergoing laparoscopic gastrointestinal surgery.Methods:From January 2019 to February 2020, 90 patients undergoing elective laparoscopic gastrointestinal surgery under general anesthesia in the Third Affiliated Hospital of Sun Yat-sen University were selected. They were randomly divided into 3 groups: catheterization before induction (group A), catheterization during induction (group B), and catheterization after induction (group C). In group A, patients received general anesthesia after awake catheterization. In group B, intravenous injection of DEX 0.5 μg/kg was pumped for 10 minutes, followed by catheterization and induction. In group C, patients received general anesthesia and then catheterization. Visual analogue scale (VAS) score of urethral stimulation, morphine dosage and the incidence of agitation during resuscitation were recorded. The heart rate and mean arterial pressure of the three groups were compared at the time of entering the room, catheterization, tracheal intubation, entering postanesthesia care unit (PACU), about extubation and 30 minutes after extubation.Results:The fluctuation of blood pressure and heart rate in group B was significantly less than that in group A and group C at the time of extubation and 30 minutes after extubation ( P<0.05). VAS of urethral stimulation in group B [(2.9±0.9)point] was significantly lower than that in group A [(4.4±1.8)point] when catheter was indwelling ( P<0.05). After extubation, VAS in group B [(2.8±1.1)point] was significantly lower than that in group A [(3.2±1.2)point] and C [(5.2±1.8)point] ( P<0.05). The utilization rate of morphine within 24 hours after surgery in group B (10%) was significantly lower than that in the other two groups (40%, 57%), and the incidence of postoperative agitation in group A and B was lower than that in group C within PACU ( P<0.05). The satisfaction of patients in group B (86.7%) was higher than that in group A (70%) and C (46.7%). The satisfaction of PACU personnel in group A (76.7%) and B (80%) was significantly higher than that in group C (43.3%). Conclusions:Sedation with dexmedetomidine during urethral catheterization can reduce urethral stimulation during resuscitation and improve patients' and PACU staffs' satisfaction.

Objective To evaluate the long-term therapeutic results and the safety of nephronsparing surgery(NSS) for the treatment of renal cell carcinoma. Methods Clinical data of 243 NSSfor renal cell carcinoma were retrospectively analysed. Of them, 159 were males and 84 were femaleswith average age of 58 years (range from 24 ?77 years). The average tumor size was 3. 4 cm (rangefrom 1.1 to 6. 7 cm). Three cases were solitary renal cell carcinoma, 11 were bilateral renal cell carcinoma; 237 cases were in stage T_(1a). and 6 cases were in stage T_(1b). No lymph node and distant metastasis, no renal vein cancer tumor embolus and inferior vena cava tumor embolus was found. Postoperative follow-up was carried out by ultrasound, CT and renal function. Cancer specific survival was estimated using Kaplan-Meier method and log-rank test. Results After a mean 31 months (1-147months) follow-up, long-term follow-up data were obtained in 232 cases because the other 11 did notlive in Dalian, 52 were treated with interferon. Four of the 232 patients treated with NSS had died:1died from lung cancer 16 months after lung cancer treatment, the other 3 died from cardiovascular diseases. The total survival rate and cancer specific survival rate were 98. 3% and 100. 0%, respectively.Local tumor recurrences were detected in 5 patients and tumor metastasis was detected in 1 patient.The recurrence rate was 2. 2%, and the metastasis rate was 0. 4%. The complications included temporary renal failure and urine leakage. The complication rate was 5. 6%. Conclusions NSS for renalcell carcinoma is a safe and feasible treatment option. It has the advantages of low local recurrence,good long-term survival rate and low complication rate. NSS can maximally reserve functional nephron, reduce the risk of chronic renal failure, preserve patient's quality of life and increase patient'ssatisfaction.
