OBJECTIVETo observe the efficacy and safety of Qizhi Jiangtang Capsule (QJC) in treating stage 3b diabetic kidney disease (DKD) patients with macroalbuminuria.
METHODSPatients who conformed to the diagnostic criteria of stage 3b DKD were randomly assigned to two groups according to random digital table, the experiment group and the control group, 84 in each group. All patients received a two-week elution period, and then were treated with basic Western therapy. Patients in the experiment group took QJC, 5 pills per time, 3 times a day, while those in the control group took Valsartan Capsule 160 mg each time, once daily. The observation period of follow-ups was limited within 6 months, and the time points were set as the baseline, 1st month, 3rd month, and 6th month. Systolic blood pressure (SBP), diastolic blood pressure (DBS), 24 h urine protein quantitative (24 h UPQ), plasma albumin (ALB), and serum creatinine (SCr) were detected and recorded, and estimated glomerular filtration rate (eGFR) was calculated. The occurrence of hypoglycemic reaction, coagulation disorder, gastrointestinal tract reaction, allergy, hyperkalemia, doubling of creatinine, and overall adverse events were observed and recorded at same time.
RESULTSFinally 81 patients in the experiment group and 80 patients in the control group were effectively included. Compared with the baseline level, SBP and DBS obviously decreased in the control group at month 1 of treatment (P < 0.05), and more significantly decreased at month 6 of treatment (P < 0.01). SBP at month 1, 3, and 6 of follow-ups; DBS at month 6 of follow-ups was lower in the control group than in the experiment group (P < 0.05). At month 1, 3, and 6 of follow-ups, 24 h UPQ of the experiment group was significantly lower than the baseline level (P < 0.01). It was also significantly lower than the level of the control group at the same time point (P < 0.05). There was no significant difference in 24 h UPQ at month 1, 3, and 6 of follow-ups between the control group and the baseline level (P > 0.05). ALB of the experiment group showed an increasing trend. It was significantly higher than the baseline level at month 6 (P < 0.05), which was also higher than that of the control group at same period (P < 0.05). There was no significant difference in the ALB level in the control group (P > 0.05). SCr of two groups showed an increasing trend. SCr of the experiment group was significantly higher at month 1, 3, and 6 follow-ups than the baseline level (P < 0.05). But the increment of SCr was higher in the control group than in the experimental group, and obviously higher than the baseline levels (P < 0.05). eGFR of both groups showed a decreasing trend. The decrement was higher in the control group than in the experimental group (P < 0.05). The proportion of progression of renal functions at month 1, 3, and 6 of follow-ups in the experimental group was 0.0% (0 case), 9.55% (8 cases), and 21.4% (18 cases), while they were 8.3% (7 cases), 21.4% (18 cases), and 40.5% (34 cases) in the control group. There was no statistical difference in the proportion of progression of renal functions between the two groups at month 3 and 6 of follow-ups (P < 0.05). There was no statistical difference in the incidence of adverse reactions between two groups (P > 0.05).
CONCLUSIONQJC could effectively reduce urinary protein of patients with stage 3b DKD, and delay the progression of renal functions.

Objective To investigate the radiobiological effects of radiation with different dose rates on human nasopharyngeal carcinoma cell line CNE-2 treated with or without a poly ADP-ribose polymerase (PARP) inhibitor,olaparib.Methods The concentration of olaparib used to treat cells equaled to the inhibition concentration IC10 of olaparib to CNE-2 cells.The CNE-2 cells were divided into acute radiotherapy (RT) group,fractionated radiotherapy (FRT) group,olaparib + RT group,and olaparib + FRT group.All groups were exposed to radiation of 0,1,2,3,5,7,and 10 Gy at a dose rate of 3 Gy/min.The delivery time for each dose point was 4 min in RT and 30 min in FRT.The colony forming assay was used to evaluate the survival of CNE-2 cells at each dose point.The multi-target,single-hit model was used to fit the cell survival curves and the parameters,D0,Dq,and SF2,were calculated.At dose points of 0.1,and 2 Gy,western blot was used to determine the expression of PARP-1 in the RT group and the FRT group and γH2AX in each group.Immunofluorescence was used to evaluate the γH2AX focus formation.A single factor analysis of variance was used to compare the 4 groups,and two two compared with SNK-q test.Results The IC10 value of olaparib to CNE-2 cells was 4.0 μmoL/L.At dose points of 1 and 2 Gy,the PARP-1 expression was significantly higher in the FRT group than in the RT group (P=0.029,0.022),while the γH2AX focus number was significantly smaller in the FRT group than in the other three groups (all P<0.05);compared with the RT group,the D0,Dq,and SF2 values in the FRT group were increased by 11.67%,15.78%,and 23.61%,respectively;compared with the FRT group,the D0,Dq,and SF2 values in the Olaparib+ FRT group decreased by 11.19%,6.44%,and 13.26%,respectively;there were no significant differences in above indices between the RT group,the Olaparib+RT group,and the Olaparib+FRT group.Conclusions For the same radiation dose,fractionation reduces the relative dose rate and weakens the radiobiological effects.lowdose olaparib can compromise the single strand break repair induced by the decline of the relative dose rate in a fractionated irradiation mode,which promotes the formation of double-strand break and improves the radiobiological effects.

Objective Pancreas perfusion is an essential step in human islet isolation.To develop the new methods for introductal canulation,collagenase infusion and to observe their effects on islets isolation.Methods A total of 17 pancreases were digested from March 2005 to April 2010.The pancreases were distended by three methods:the standard method (n =3),the one-cannula method (n =11) and three-cannula method (n =3).In the standard group,the pancreases were completely cut into half at the mid-body.Two catheters were inserted into the main duct:one directed toward the tail and the other to the head.In the one-cannula method group,a long tube was inserted into the duct at the head,advancing to the tail In the three-cannula method group,pancreatic parenchyma was then minimally cut at the mid-body and three catheters were inserted into the main pancreatic duct:one at the head (the first catheter) and two at the mid-body,one toward the tail (the second catheter) and the other toward the head (the third catheter).The pancreases were digested by improved Ricordi technique.Ficoll continuous density/grads centrifuge method was performed to purify the islets.DTZ staining was adopted to identify islets and count islet equivalent (IEQ). AO/EB fluorescence examination was used to count active islet percentage.Static glucose stimulating test (SGS) in vitro was designed to estimate islet function and calculate SI.Results The distension volume of the threecannula method group was 1.24 rnl/g pancreas,and higher than the other groups (for the standard group:0.71 ml/g pancreas; for one-cannula method group:0.96 ml/g pancreas,P<0.05).The yield of islet in the three-cannula method group and the one-cannula method group was 2514 and 2270 IEQ/g,which was significantly more than that in the standard group (1914 IEQ/g pancreas,P<0.05).The purity and viability of the islets were 74 %/79.3 %,75.6 %/79.4 % and 78.3 %/84.0 % respectively in the three groups with the difference being not significant among the groups.SI in the one cannula method group (4.74) and the three-cannula method group (5.27) was significantly higher than that in the standard group (3.46).ConclusionThe three-cannula method improved collagenase infusion and the islet yields.

Objective To assess the clinical value of high-frequency electrocautery in the treatment of massive hemorrhage of presacral venous plexus. Methods The clinical data of 8 patients with presacral venous hemorrhage treated with high-frequency electrocautery from February 2005 to March 2008 were analyzed. Once the presacral venous hemorrhage happened, the bleeding site was pressed with a gauze or finger and the accumulated blood was aspirated. Then, while simultaneously withdrawing the gauze or finger over the bleeding sites, high-frequency electrocautery was applied with a power of 80-100 W to coagulate all the bleeding sites. Results High-frequency electrocautery was used to stop bleeding in the 8 patients, and no electrocautery related complica-tions occurred postoperatively. Conclusions High-frequency electrocautery for massive hemorrhage of presacral venous plexus is simple, efficient and safe.

Objective To explore the clinical efficacy of artificial blood vessel sheath around re-nal vein for the treatment of left renal vein entrapment syndrome. Methods Eight cases with left re-nal vein entrapment syndrome (7 males and 1 female, mean age, 16 years) with history of gross hema-turia for 6 to 36 months were reviewed. Doppler ultrasound reports suggested compression of the left renal vein at mesenteric angle in all eases. CT scan showed the abnormal angle between aorta and su-perior mesenterie artery in 5 cases. Cystscopy showed hematuria from the left ureteral orifice in 5 ca-ses. All cases with left renal vein entrapment syndrome were treated ,with the method of putting artifi-cial blood vessel as a sheath around left renal vein. Results The operations were all successful. The average operation time was 150 min, the average blood loss was 50 ml, and the average hospital stay after operation was 9 d. No surgical complications occurred. The gross hcmaturia disappeared in 6 ca-ses and Doppler ultrasound showed that left renal vein outflow was normal in 7 when the patients dis-charged from the hospital. The gross hematuria disappeared during 2-24 months' follow-up in 7 pa-tients. Conclusions The surgical aim of renal vein entrapment syndrome is to reduce the compres-sion of renal vein. The method of putting artificial blood vessel around renal vein could be a simple, safe and effective method.

Objective To develop a tool capable of early and exactly predicting various outcomes in comatose survivors who restore spontaneous circulation after cardiopulmonary resuscitation (CPR) and validate its performance.Methods Variables that were both readily available and predictive of outcomes were identified by systematically reviewing published literature on resuscitation.A value was assigned to these variables.We used these variables in combination with APACHE Ⅱ/score to devise a multifactorial prediction score system,which we called PRCSs Prognostication Score (PRCSs-PS).Outcomes in 115 hospitalized comatose survivors after CPR were retrospectively reviewed using PRCSs-PS.Score of patients with different outcomes was compared.The area under the receiveroperating characteristic (ROC) curve was determined to evaluate performance of this tool to identify patients with a poor outcome (CPC4 and 5) and other outcomes (CPC1,2,and 3).Results There were differences of PRCSs-PS score among multiple groups with five different outcomes (CPC1-5)(F=65.91,P=0.000).Pairwise groups with different CPC were compared:no significant difference was noted between CPC 1 and CPC2 (12.41±6.49 vs 17.38±6.91,P=0.092),but difference between other pairwise CPC groups was statistically significant (CPC2 vs CPC3:17.38±6.91 vs 24.50±5.80,P=0.041,CPC3 vs CPC4:24.50±5.80 vs 32.29±5.24,P=0.006).The performance of PRCSs-PS to discriminate patients with a poor outcome from patients with other outcomes went as follows:it had 100% sensitivity,78.6% specificity,and 178.6 diagnostic index at the score cut-off22.5; it had 77.8% sensitivity,100% specificity and 176.4 diagnostic index at the score cut-off32.5.Score 23 and 33 were two key cut-offpoints.The area under the ROC curve was 0.968,showing excellent discrimination.Conclusions The final outcomes in post-resuscitation comatose survivors can be accurately predicted using PRCSs-PS Score.

Objective To investigate the effect of paclitaxel drug-coated balloon (DCB) dilatation in treating coronary in-stent restenosis (ISR) occurring after drug-eluting stent (DES) implantation,and to observe the long-term changes of the target vascular lumen area in order to clarify the curative effect of paclitaxel DCB in treating ISR.Methods Four patients with ISR whose clinical condition met the DCB indication were selected.According to the standard process,sufficient pre-expansion of ISR was performed first,then paclitaxel DCB dilatation was carried out to dilate the lesion segment of ISR,and no stent was implanted.Both coronary angiography and intravascular ultrasound (IVUS) were performed immediately after the treatment as well as 9 months to measure the minimum lumen area (MLA) and cross-sectional area (SA) of the stent,and the intimal hyperplasia was also been evaluated.Results In all 4 patients,angiography performed immediately after paclitaxel DCB dilatation showed that neither dissection of the dilated segment of the target artery nor obvious residual stenosis was observed.Angiography performed 9 months after the treatment revealed that all dilated segments of the target arteries were patent,and no pronounced restenosis of stent segment was seen.IVUS examination was indicated that MLA became enlarged,SA showed an increasing trend,and intimal hyperplasia showed a tendency to be inhibited.Conclusion For the treatment of ISR,pure paclitaxel DCB dilatation can obtain long-term lumen area enlargement,thus,repeated stent implantation can be avoided,which,in turn,can reduce the risk of ISR recurrence.Paclitaxel DCB dilatation can locally release paclitaxel,which has curative effect on the coronary artery wall to inhibit the excessive proliferation of intima.
