Objective To report a retroperitoneal laparoscopic surgery for ureteropelvic junction obstruction (UPJO) by double renal veins.Methods A 28-year-old male patient with left low back pain for 6 months was diagnosed as left hydronephrosis and UPJO.A ureteral stent had been placed 3 months before and failed to improve hydronephrosis,so the ureteral stent was pulled out.CT scan showed that left UPJ went through the two renal veins,suggesting UPJO.Nephrogram showed that left GFR and right GFR were 35 ml/min and 34 ml/min,respectively.These results indicated mechanical obstruction of left upper urinary tract.The patient underwent retroperitoneal laparoscopic Anderson-Hynes dismembered pyeloplasty.Results The surgical procedure was successful.Two left renal veins were found,and the ventral one was in front of ureter,compressing the ureter.An aberrant renal artery went into left kidney with the ureter.0.5 cm stenosis of ureteropelvic junction was excised,and pyeloplasty was performed.A ureteral stent was placed into the ureter,then the pelvis and the ureter were sew up in front of the ventral renal vein.The surgical time was 240 min,and blood loss was 50 ml.Postoperative hospital stay time was 4 d.During 4 months' follow up,hydronephrosis was attenuated significantly.Conclusion Retroperitoneal laparoscopic surgery for UPJO with aberrant two renal vein might be a minimally-invasive and effective procedure.

Objective To evaluate the application of health education in patients with cholecystectomy. Methods From October 2009 to July 2010, 93 patients in our hospital with cholecystectomy were randomly divided into the control group (45 cases) and the observation group(48 cases). The control group was given routine nursing care, the observation group received perioperative health education in addition to the routine nursing care, then compared the nursing effect of two groups. Results In the observation group, the patients' knowledge and awareness rate of their own disease was 95.8%, and the control group was 80.0%, the difference was statistically significant between two groups. The recovery of gastrointestinal function in the observation group was significantly better than the control group, the difference was statistically significant between two groups. Conclusions Health education can enable patients with cholecystectomy correct understanding of their disease, eliminate negative emotions, and help the recovery of gastrointestinal function in patients, which is worthy of attention.

Objective: To analyze the efficiency of ureteroscope and biopsy in the diagnosis of tumor grade, muscle-invasiveness and multifocality in suspected upper tract urinary carcinoma (UTUC) patients in order to find out whether it can be used in the risk stratification of UTUC patients.Methods: A retrospective study of 76 UTUC patients who underwent preoperative ureteroscope and/or biopsy and received radical nephroureterectomy in Peking University Third Hospital during January 2014 to December 2016 was undertaken.Results: In this study, 76 patients were included.There were 31 males (40.8%), and 45 females (59.2%).The median age was 64.5 years (31-88), and 51 patients had the symptom of hematuresis.The tumor was located in renal pelvis in 39 patients, and in ureter in 37 patients.Post-operative pathology confirmed that all the 76 patients included in this study suffered from UTUC, of whom 21 (21.6%) were of low-grade, 51 (67.1%) were of high-grade, 4 (5.3%) were undetermined, and 47 (61.9%) patients were muscle-invasive, and 27 (35.5%) were not, and 2 (2.6%) were undetermined.Among the 50 patients, in whom the grade of the tumor could be diagnosed by biopsy, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value for low-grade tumor was 88.2%, 69.7%, 76.0%, 60.0% and 92.0%, respectively.Among the 27 patients, in whom the muscle-invasiveness could be diagnosed by biopsy, 5 patients were diagnosed with muscle-invasiveness, all confirmed by pathology after surgery and 22 patients were diagnosed with none muscle-invasiveness, turned out to be 50% muscle-invasive and 50% none-muscle invasive after surgery.The accuracy was 59.3%.The accuracy of ureteroscopic biopsy to diagnosis multifocality was 61.0%.On univariate ana-lysis, biopsy grade was associated with postoperative pathology (P=0.001), while gender, age, side, body mass index (BMI), hematuresis, preoperative estimated glomerular filtration rate (eGFR), hydronephrosis, tumor size, location, multifocality and sessile were not associated with postoperative pathology grade.Biopsy grade (P=0.02), preoperative eGFR<90 mL/(min·1.73 m2)(P=0.025) and tumor located in pelvis (P=0.049) were associated with muscle invasiveness.Gender, age, side, BMI, hematuresis, hydronephrosis, tumor size, multifocality and sessile were not significantly associated with muscle invasiveness.Conclusion: Ureteroscope and biopsy can assist risk stratification in upper tract urothelial carcinoma patients.

Objective To discuss the clinic characters of clear cell papillary renal cell carcinoma ( CCPRCC) and the efficacy of related laparoscopic surgery.Methods From October 2013 to December 2015, 4 cases were treated as CCPRCC including 3 male and 1 female.Their age ranged from 34 to 67 years old ( mean 53 years old) .The duration of illness ranged from 7 days to 3 months, which the average duration was 1.5 months.The location of tumor included left side in 2 cases and right side in other 2 cases.All tumors were found incidentally, without symptoms or positive sign.Ultrasound showed that 2 cases were solid, and the other 2 cases were cystic solid with low, high or mixed echo and rich blood flow signals.The tumors were enhanced in CT arterial phase, and calcification showed in one case.MRI showed heterogeneous signal.The mean size of tumor was 3.0 cm,ranging 2.3 to 4.5 cm.After preoperative examination, all cases underwent retroperitoneal laparoscopic partial nephrectomy.During the operation, 2 cases were confirmed as cystic solid tumors, and the other 2 cases were solid tumors.Renal artery and renal mass were dissociated , then the artery was blocked.The tumor was complete resected, and kidney was sutured. Results All surgery was performed successfully without conversion.The operation time was 137-191 min (average 157 min).The blood loss was 10-100 ml (average 45 ml) without blood transfusion.The warm ischemia time was 15-35 min ( mean 22 min) .The postoperative hospitalization time stay 6-8 d ( average 7 d).Pathologic report was CCPRCC, including 3 cases of WHO/ISUP grade 1, and 1 case of WHO/ISUP grade 2.2 cases were cystic solid tumor, and other 2 cases were solid tumor.Bland-appearing tubules and occasional small papillae, and uniform small nuclei are arranged in a linear manner away from the basal aspect of the tubules in microscope.Immunohistochemistry showed that CA IX, CK7, 34 E12 were positive, but CD10 , P504S and CD117 were negative.The mean duration of postoperative follow-up was 14 months, ranging 4 to 30 months.No recurrence was found in those patients.Patients were followed up for 4-30 months ( average 14 months) without recurrence or metastasis.Conclusions CCPRCC is a rare subtype of renal tumor, which mainly diagnosed by pathological diagnosis . Retroperitoneal laparoscopic partial nephrectomy is an effective method for the treatment with good prognosis.

SUMMARY Anaphylaxis is an acute and fatal systemic allergic reaction to an allergen , and it could be an unpre-dictable and life-threatening cause during anesthesia .The main purpose of this paper is to report a case of anaphy-lactic shock during the anesthesia induction and to review the prophylaxis and treatment of anaphylactic reactions and anaphylactoid reactions during the anesthesia period .A 63-year-old man, with a mass on his adrenal , was scheduled to a laparoscopic adrenal tumor excision .During the anesthesia induction period , after administrated sul-fentanil, propofol and rocuronium , the blood pressure was decreased and the heart rate was increased .Then, the patient had rash on his whole body and developed an anaphylactic shock .After being treated with the anti-allergic agents and norepinephrine , the rash disappeared and the vital sign become stable .The patient felt nothing uncom-fortable during the two weeks ’ follow-up.Anaphylactic reactions and anaphylactoid reactions are not rare during the anesthesia period .The most common inducements are muscle relaxant , latex and antibiotics .Anaphylactic reac-tions in the perioperative period are often serious and potentially life-threatening conditions , involving multiple or-gan systems in which the clinical manifestations are the consequence of the release of preformed mediators from mast cells and basophils .Before anesthesia , we should acquire the allergic history .During the anesthesia period , the vi-tal sign and the skin should be observed carefully .

Background::Although the impact of tumor complexity on peri-operative outcomes has been well established using several nephrometry scoring systems, the impact of adherent perirenal fat remains poorly defined. This study aimed to develop a novel nephrometry scoring system for predicting the peri-operative outcomes of laparoscopic partial nephrectomy (LPN) by integrating and optimizing the RENAL score (RNS) and Mayo adhesive probability (MAP) score.Methods::We retrospectively evaluated 159 patients treated with retroperitoneal LPN. The patients’ demographic parameters, RNSs, and MAP scores were evaluated as potential predictors of perioperative outcomes, including operation time, estimated blood loss (EBL), and margin, ischemia, and complication (MIC) achievement rate. The independent predictors were used to develop a novel nephrometry scoring system. The predictive value and inter-observer agreement for the novel nephrometry scoring system were evaluated.Results::Tumor radius (R score), nearness to the renal sinus or collecting system (N score), and posterior perinephric fat thickness were independent predictors of peri-operative outcomes and were used to develop the RNP score. The univariate analysis revealed that the RNP score was significantly associated with operation time, EBL, and MIC achievement rate ( P < 0.050). The RNP score was an independent predictor of operation time ( P < 0.001), EBL ( P = 0.018), and MIC achievement rate ( P = 0.023) in the multivariate analysis. The RNP score was not inferior to RNS in the area under the curve for predicting peri-operative outcomes and performed better in inter-observer agreement (76.7% vs. 57.8%) and kappa value (0.804 vs. 0.726). Conclusion::The RNP score, combining the advantages of the RNS and MAP score, demonstrated a good predictive value for the peri-operative outcomes of retroperitoneal LPN and better inter-observer agreement.

OBJECTIVETo evaluate the effect of health education on lung function and quality of life in stabilized patients with chronic pulmonary disease (COPD).

METHODS117 stabilized COPD patients were randomly devided into 4 groups with numbers as 31,26, 20 and 40 identified as Groups 1 to 4. Patients in Group 1 did not receive health education, but Groups 2,3 and 4 received one, two, three or more times health education in file. FEV1, FEV1%, FEV1/FVC and SGRQ score were compared pre and 6-month post the health education program.

RESULTSHealth education seemed successful in delaying the decline of FEV1, FEV%, FEV1/FVC and groups 2-4 were superior to group 1(P < 0.05) while groups 3 and 4 were superior to groups 1 or 2(P < 0.05). Health education was effective in raising the SGRQ score among the stabilized COPD patients with groups 2-4 superior to group 1 (P < 0.05) while groups 3 and 4 superior to groups 1 or 2 (P < 0.05).

CONCLUSIONHealth education could effectively delay the decline of both lung function and quality of life in stabilized patients with COPD.

It has been shown that mitochondria not only control their own Ca(2+) concentration ([Ca(2+)]), but also exert an influence over Ca(2+) signaling of the entire cell, including the endoplasmic reticulum or the sarcoplasmic reticulum, the plasma membrane, and the nucleus. That is to say, mitochondria couple cellular metabolic state with Ca(2+) transport processes. This review focuses on the ways in which the mitochondrial Ca(2+) handling system provides integrity and modulation for the cell to cope with the complex actions throughout its life cycle, enumerates some indeterminate aspects about it, and finally, prospects directions of future research.
