ABSTRACT
【Objective】 To introduce the key techniques of "one-cut" circumcision, and to compare its clinical efficacy with traditional circumcision. 【Methods】 A retrospective analysis was conducted on 120 cases of circumcision in our center during Jul.2020 and Jul.2022, including 60 cases in the "one-cut" group and 60 cases in the traditional circumcision group. The operation time, postoperative edema time, satisfaction with cosmetics and improvement of sexual life were compared between the two groups. 【Results】 Compared with the tradition group, the "one-cut" group had shorter operation time [(19.2±7.4) min vs. (23.1±1.7) min, P<0.001] , shorter postoperative edema time [(5.5±3.2) d vs. (9.6±5.5) d, P<0.001] , and higher satisfaction with cosmetics [(3.6±0.5) vs. (3.1±0.8), P<0.001)] , but there was no difference in improvement of sexual life between the two groups (P=0.08). 【Conclusion】 "One-cut" circumcision is easy to operate, with short operation time, fast postoperative recovery, neat incision and satisfactory appearance, which is worth popularizing.
ABSTRACT
OBJECTIVE To investigate the effects of Cistanches Herba polysaccharides （abbreviated as CDPS） on rats with constipation-predominant irritable bowel syndrome （IBS-C）. METHODS SD rats were divided into control group （20 rats） and modeling group. The modeling group was given 2 mL of normal saline at 0-4 ℃ intragastrically （once a day， for 14 consecutive days） to induce IBS-C model. After modeling， model rats were grouped into model group， positive control group （mosapride citrate， 1.35 mg/kg）， CDPS low-dose group （50 mg/kg） and CDPS high-dose group （100 mg/kg）， with 20 rats in each group. Administration groups were given corresponding drug solution intragastrically， and control group and model group were given a constant volume of water intragastrically， once a day， for 28 consecutive days. The fecal water content， serum content of 5-hydroxytryptamine （5-HT）， and charcoal powder propulsion rate of rats were determined in each group；the pathological morphology of colon tissue was observed， and mRNA and protein expressions of nerve growth factor （NGF） and tropomyosin receptor kinase A （TrkA） in colon tissue were detected. RESULTS Compared with control group， the fecal water content and carbon powder propulsion rate in the model group were decreased significantly （P＜0.05）； the rupture of mucosal muscle layer in colon tissue， significant infiltration of inflammatory cells and cellular edema were observed； the content of 5-HT in serum， and relative mRNA and protein expressions of NGF and TrkA were increased significantly （P＜0.05）. Compared with model group， the fecal water content and carbon powder propulsion rate of rats were increased significantly in administration groups （P＜0.05）， and pathological changes of colon tissue were relieved significantly， while the content of 5-HT in serum， the mRNA and protein expressions of NGF and TrkA in colon tissue were decreased significantly （P＜0.05）； among them， the above indicators inthe positive control group and CDPS high-dose group were generally close to those in the control group （P＞0.05）. CONCLUSIONS CDPS can alleviate the symptoms of IBS-C rats， which may be related to the inhibition of NGF/TrkA signaling pathway.

Objective:To explore the risk factors of pulmonary infection in elderly (aged 60+ years) kidney transplant recipients.Methods:The clinical data were retrospectively analyzed for 119 elderly kidney transplant recipients from January 2010 to January 2019 . According to whether or not pulmonary infection occurred after renal transplantation, the recipients were divided into infected group (n=40) and non-infected group (n=79). Clinical data was analyzed for two groups. The relevant risk factors of gender, age, donor type, body mass index, history of smoking, preoperative dialytic time, preoperative dialysis, immune induction, immune maintenance, presence or absence of delayed graft function, leucopenia, serum creatinine before infection, venous hormone shock therapy or not, diabetic history before or after surgery, history of coronary heart disease, history of hepatitis B virus, prophylactic dosing of compound sulfamethoxazole, prophylactic valganciclovir or ganciclovir, were examined by univariate analysis and multivariate logistic regression analysis.Results:The incidence of pulmonary infection in elderly kidney transplant recipients was 33.6% (40/119). In infected group, 15 patients died of severe pulmonary infection with a mortality rate of 37.5%(15/40). History of smoking (OR=10.58, 95%CI: 1.98-56.40, P=0.006), venous hormone shock therapy (OR=25.06, 95%CI: 4.25-147.71, P<0.001) and preoperative dialytic time (OR=1.032, 95%CI: 1.003-1.062, P=0.033) were the risk factors for pulmonary infection in elderly kidney transplant recipients. Conclusions:The incidence and mortality of lung infection are higher in elderly kidney transplant recipients. Smoking history, venous hormone shock therapy and long preoperative dialytic are associated with pulmonary infection in elderly kidney transplant recipients.
ABSTRACT
Objective To summarize the clinical treatment experience of carbapenem-resistant Klebsiella pneumoniae (CRKP) infection after renal transplantation in donation after cardiac death (DCD) era. Methods Clinical data of 10 donors and 17 recipients with CRKP infection after DCD renal transplantation from January 2015 to January 2019 were retrospectively analyzed. Both donors and recipients received bacterial culture and drug sensitivity test. Clinical manifestations, treatment and outcome of CRKP-infected recipients were recorded. Results Seven donors were infected with CRKP. After pretreatment, CRKP in 2 cases turned negative, CRKP in 5 donors did not turn negative. All renal grafts were treated with tigecycline+meropenem+voriconazole lavage to prevent infection. Among 17 recipients with CRKP infection, 11 cases were positive for blood culture, 10 positive for urine culture, 3 positive for sputum culture, 3 positive for incisional secretion and 3 positive for retroperitoneal drainage. Clinical manifestations included fever in 8 cases, rupture and hemorrhage of the transplant renal artery in 7 cases or thrombosis in the transplant renal artery in 1 case, bladder irritation sign in 3 cases and cough with brick red jelly-like sputum in 1 case, respectively. Five patients were treated with tigecycline+meropenem, 1 patient suffered from renal graft loss and 4 recipients died. Twelve patients were treated with ceftazidime-avibactam +meropenem, 3 patients presented with renal graft loss and 1 recipient died. Conclusions CRKP-infected donor is not the absolute contraindication of renal transplantation. Pretreatment of donor infection and early administration of sufficient sensitive antibiotics can cure CRKP infection and improve the clinical prognosis of renal transplant recipients.
ABSTRACT
Objective To investigate the clinical characteristics of DCD donor-derived CRKP infection and bleeding in kidney transplantation,and to summarize the experience of diagnosis,treatment and prevention.Methods A retrospective analysis was carried out from July 2016 to December 2017 in hospital,containing clinical data of 4 cases of CRKP-infected DCD donors and 7 cases of kidney transplantation recipients.Results In the CRKP culture of 4 cases of DCD donors,1 case was positive for blood culture,1 case was positive for urine culture,1 case was positive for sputum culture,and 1 case was negative for blood,urine and sputum culture.The corresponding 7 recipients were all positive for blood culture after renal transplantation,4 cases were positive for urine culture,3 cases were positive for sputum culture,and 5 cases were positive for perirenal drainage.Of the 7 patients,4 cases had renal artery hemorrhage,1 of them was died.The average bleeding time was 17.75 days after operation (14-19 days).In 7 patients with renal transplantation,CRP increasd.And in 3 cases of deaths,CRP was stably higher than normal.Meanwhile,CRP in 4 surviving patients gradually decreased to the normal range after effective anti-infection treatment.All 7 patients were treated with carbapenems;2 patients were dead without avibactam therapy;and 5 cases were treated with avibactam and carbapenems and survived,1 case died and 1 case had good renal function recovery.Conclusion Positive CRKP in blood,urine and sputum of DCD donors can lead to CRKP infection in kidney transplant recipients.Even if the body fluids of donors are all negative,the false negative results could not be excluded.Persistent or increased high-level CRP after operation is an early warning on CRKP infection.And CRP can be used as an indicator for evaluating the effectiveness of anti CRKP therapy.The combination of avibactam and carbapenem antibiotics is an effective regimen in the treatment of DCD donor-derived CRKP.
ABSTRACT
Objective To research the preventing and controlhng measure of esophageal cancer and the high-risk factors of influencing surgical effect. Method Retrospective collecting 3358 patients of the esophageal cancer by surgical treatment, and summaring and analysing the clinical material of the recent death of 94 cases after surgery. Results The recent surgical mortality was 2.8% (94/3358) in all of the esophageal cancer patients after surgery. The advanced age and the partner disease before surgery had significant influence to the recent surgical mortality (P <0.05). The tallies fistula in chest and the cardiopulmonary complication after surgery had unusual significant influence to the recent surgical mortality (P< 0.05). Surgery way and spleen excision had no influence to the recent surgical mortality (P > 0.05). Conclusions The tallies fistula in chest, the cardiopulmonary complication after surgery, the advanced age and the partner disease before surgery are the high-risk factors of the recent death to esophageal cancer after surgery.Purposeful controlling these factors will be possible to reduce the surgical complication and the recent surgical mortality.

ABSTRACT
Objective To study the toxic effect of glufosinate-ammonium on the liver. Methods SD rats aged 6 weeks with weight of 140-160 g were randomly divided into four groups, 20 (10 males and 10 females) in each group. The rats were treated for three months by gavaging different doses of glufosinate-ammonium (0, 100, 250, 500 mg/kg bw) for the experimental group and 2% Tween-80 solution for the control group. All the rats were weighted once a week. The activity of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) in the serum were determined at the end of the study. Liver weight was measured and liver index was calculated. Pathological examination was performed. Results Treated with high-dose of glufosinate-ammonium, a retarded growth of rats was seen, the activity of ALT, AST and ALP increased significantly in both male and female rats, the liver index increased significantly and pathological changes of the liver were also observed compared with the control. No significant changes were found in the rats treated with moderate and low dose compared with the control. Conclusion Glufosinate-ammonium may produce a toxic effect on the liver of rat when the exposed dose is more than 500 mg/kg.
