Objective To observe the effect of cefoperazone sulbactam on the efficacy inflammatory factors in patients with sepsis. Methods 80 cases of sepsis patients from January 2014 to April 2015, were double-blindly, randomized divided into control group(41 cases) and observation group(39 cases). The control group was treated with conventional treatment methods, the observation group was treated with cefoperazone sulbactam. After treatment, Leukocyte IL-6, IL-10, IL-1 and C- reactive protein (CRP) levels of interleukin and curative effect in the two groups were analyzed. Results After treatment, the levels of IL-6, IL-10, IL-1, CRP in the observation group were lower than those in the control group (t=15.555;t=11.122; t=9.379; t=34.782), the difference was statistically significant (P<0.05); The total effective rate in the observation group was 95.12%, which was significantly higher than that in the control group (76.93%), and the difference was statistically significant (P<0.05); The proportion of painless and severe pain in the observation group was significantly lower than that in the control group(76.93%), and the difference was statistically significant (P<0.05). Conclusion Cefoperazone sulbactam is effective in the treatment of sepsis, can improve the efficacy of treatment, it is a safe and effective treatment, should be promoted and used in clinical.

Crystal power/epoxy resin composite was made with refined crystal power as filling material in different composition. The shearing strength and coefficient of thermal expansion of the crystal powder/epoxy resin composite was studied. The sectional morphology was observed under a scanning electron microscope. The results of the study indicate that the shearing strength of crystal powder/epoxy resin composite is improved while the coefficient of thermal expansion decreases with increase of the amount of crystal powder, and a well-proportioned three-dimensional structure is obtained. The augmentation of shearing strength exhibits no linear relationship to the amount of crystal powder, and there is an optimal amount for crystal powder filling. The coefficient of thermal expansion is decreased with increase of crystal powder filling, and three-dimensional structure optimization exhibits the' similar inflexion.

Objective To investigate the correlation between human leukocyte antigens-A,-B,-DRB1 (HLA-A,-B,-DRB1) high resolution alleles and chronic renal failure (CRF) caused by immunoglobulin-a nephropathy (IgAN).Method The polymerase chain reaction-sequence-based typing (PCR-SBT) method was used to investigate the genotypes of HLA-A,-B and-DRB1 high-resolution alleles in 191 cases of CRF caused by IgAN (experimental group) and 503 healthy blood donors (control group).The alleles frequencies between two groups were compared and the association between CRF caused by IgAN and the polyrnorphism of HLA was analyzed.Result (1) There were 25 alleles at A locus,48 alleles at B locus and 32 alleles at DRB1 locus in experimental group.(2) The genetic frequency of HLAA * 2901 [Pc =0.033,OR =10.738,95％ CI (1.193,96.691)],HLA DRB1 * 1106 [Pc =0.0001,OR =0.969,95％ CI (0.944,0.994)],HLA-DRB1 * 1202[Pc =0.002,OR =1.859,95％ CI (1.259,2.745)],HLA-DRB1 * 1401 [Pc =0.021,OR =0.984,95％ CI (0.967,0.998)],HLA-DRB1 * 1602[Pc=0.015,OR=1.915,95％ CI (1.157,3.17)] in experimental group was higher than in control group (P＜0.05).Conclusion There is susceptibility association of HLA-A * 2901,HLA-DRB1 * 1106,HLA-DRE * 1202,HLA-DRB1 * 1401,HLA-DRB1 * 1602 with CRF caused by IgAN.It is concluded that there is a close genetic and immunological correlation between HLA alleles and the pathogenesis of CRF caused by IgAN.

Purpose To explore the clinical value of color Doppler ultrasound in monitoring hemodynamic changes in main renal artery of neonatal asphyxia. Materials and Methods A total of 60 cases of neonatal asphyxia were divided into mild asphyxia (38 cases) and severe asphyxia (22 cases) according to Apgar score 1 min after born. Then the peak systolic velocity (Vs), the end diastolic velocity (Vd) and the resistance index (RI) of the main renal artery were obtained by color Doppler ultrasound on day 1 and day 3;the level of endothelin-1 (ET-1) was also recorded accordingly. The above results were compared with those of 20 cases of healthy full-term new born infants. Results On day 1, Vs and Vd of the main renal artery in the groups with mild asphyxia and severe asphyxia were both lower than those in healthy group (P<0.05), but RI was higher (P<0.05), with more dramatic changes in the group with severe asphyxia (P<0.05). On day 3, Vs and Vd in the groups with mild asphyxia and severe asphyxia reduced compared with those on day 1, whilst RI was higher than that on day 1. Vd and RI in the group with severe asphyxia changed more significantly (P<0.01). As to the value of ET-1, both groups with mild asphyxia and severe asphyxia showed higher level than healthy group (P<0.01). More dramatic increase appeared in the group with severe asphyxia (P<0.05). In the groups with mild asphyxia and severe asphyxia, the Vs and Vd of the main renal artery were negatively correlated with ET-1 on day 1 and day 3 (r=-0.823,-0.845;P<0.01), while the RI was positively correlated with ET-1 (r=0.785, P<0.01). Conclusion Both color Doppler ultrasound imaging and neonatal urine ET-1 test can reflect degree of renal injury after neonatal asphyxia dynamically and noninvasively, which can be used to evaluate the injury severity.

Objective:To discuss the clinical efficacy of laparoscopic radical cystectomy in the treatment of bladder cancer after partial cystectomy.Methods:The clinical data of 30 patients who underwent laparoscopic radical cystectomy after PC in Sichuan Provincial People's Hospital from March 2016 to August 2020 were retrospectively analyzed. Including 24 males and 6 females with an average age was 62.5 (45.5-82.5)years.6 out of 30 cases underwent pelvic lymph node dissection during PC. All patients had definite pathological diagnosis for the high-grade urothelial carcinoma after PC, and the tumor staging was pT 2-3bN 0M 0.5 patients received postoperative adjuvant chemotherapy with gemcitabine and cisplatin, 6 received postoperative adjuvant radiotherapy, 13 received postoperative adjuvant radiotherapy and chemotherapy, and all patients were received maintenance intravesical instillation. Median time for local tumor recurrence after PC was 9(5-29) months, all patients had pathological diagnosis for the high-grade papillary urothelial carcinoma, cT 2-4N 0M 0 stage.The average tumor diameter was 3.5(2.5-4.5)cm, an average number of tumors was 2(1-3). Laparoscopic salvage cystectomy was performed after recurrence.General anesthesia, supine position, 5 ports were inserted through the abdominal approach. Standard pelvic lymph node dissection (PLND) was used to clean the pelvic lymph nodes. Those who had underwent PLND no longer clean the obturator and peripheral iliac vessels, but including the common iliac vessel and the bifurcation of the abdominal aorta and lymphatic tissues around the inferior vena cava, as well as the presacral lymph nodes. Results:All 30surgeries were successfully performed. The average operative time was 270(240-310)min, average estimated intraoperative blood loss was 180(50-300)ml, and there was no blood transfusion during the perioperative period.The average number of lymph nodes dissected was 18 (10-27). There were 4 cases with positive lymph nodes, of which 3 cases were positive for 2 obturator lymph nodes, and 1 case was positive for 3 obturator and external iliac lymph nodes. No serious intraoperative complications occurred.No lymphatic leakage occurred. The average drainage duration was 4(3-7) d, and postoperative hospital stays was 9(7-20)d. The postoperative pathology was invasive high-grade papillary urothelial carcinoma, and pathological TNM stage was pT 2-4aN 0-2M 0.13 patients received postoperative adjuvant chemotherapy. The average postoperative follow-up time was 23(3-31) months. There were 2 cases of pelvic recurrence and 1 case of retroperitoneal lymph node metastasis. These 3 cases received adjuvant chemotherapy and radiotherapy. Conclusions:Radical cystectomy should be the primary treatment for recurrence of bladder cancer after partial cystectomy.

Objective To detect the expression of CK19 in sentinel lymph node for breast cancer and to evaluate its clinical significance.Methods SLNs of 30 patients with breast cancer were successfully detected with methylene blue,both SLN and ALN were examined by hematoxylin and eosin staining ( HK staining). The expression level of CK19 in SLNs were assessed by RT-PCR and Western Blot for mRNA and Protein respectively. Results Detection positive rate of SLN melastases was 26. 67% (8/30) by HE staining,and 1 case of false negative. Through RT-PCR,12 cases,including all the positive cases detected by routine pathological examination,were detected to be positive in the expression of CK19mRNA, with a positive rate of 40. 0% ( 12/30) , and a positive rate of 36. 67% (11/30) for CK19 was observed by Western Blot There was a significant difference between RT-PCR or Western Blot methods and routine pathological examination ( P < 0.05 ) for the detection efficiency of SI.Ns melastases. Conclusions CK19rnRNA may be a potential tumor marker for detecting micrometastasis in SLNs of breast cancer. The combined utilization of locating SLNs and detecting CK19 mRNA expression by RT-PCR instead of histopathological examination can greatly enhance the detection efficiency of SLN micrometastasis of breast cancer.
