Objective To analyze clinical features and sum up experience for the treatment of ischemic bowel disease. Methods Clinical data of 73 patients with the diagnosis of ischemic bowel disease were retrospectively analyzed. ResultsTwenty-eight patients were male and 45 patients were female. The median of age was 65 years (range of 38 to 89 years). Forty-eight patients were associated with hypertension, 23%(17/73) patients had a history of coronary disease and 15% (11/73) had diabetes. Seventy patients presented symptom of abdominal pain and 93% (68/73) had hematochezia. Symptoms relieved by conservative treatment in 96% (63/66) patients. Nine patients underwent a surgery. One patient died of sepsis postoperatively. One suffered from colostomy necrosis and leakage of the rectum segment. Conclusion 1. Elder patients presenting symptoms of abdominal pain and hematochezia, especially with a history of cardio-cerebrovascular disease and diabetes should be considered for the possibility of ischemic bowel disease. 2. Most patients with ischemic bowel disease could be successfully treated by conservative therapy. 3. Surgery for patients with chronic relapsing and nonresponsible symptoms was difficult and patients often suffer from high postoperative complications.

OBJECTIVETo investigate the effect of Compound Qingqin Liquid (CQL) on the expression level of angiotensin II (Ang II) and COX-2 mRNA transcription and protein expression in the renal tissue of rats with uric acid nephropathy.

METHODSSD rats were randomly divided into the blank control group, the model group, the positive drug group, the high, moderate, and low dose CQL group according to number randomization principle. The model was established by gastrogavage of adenine, accompanied with yeast feeding. Distilled water was given by gastrogavage to rats in the blank control group and the model group. Allopurinol at the daily dose of 9.33 mg/kg was given by gastrogavage to rats of the positive control group. CQL at the daily dose of 3.77 g/kg, 1.89 g/kg, and 0.09 g/kg was respectively given by gastrogavage to rats in the high, moderate, and low dose CQL groups. All treatment lasted for 6 weeks. Rats were randomly divided at week 4 (3 in the blank control group, and 6 in the rest groups), and the rest rats were killed at week 6. The renal tissue was extracted. The expression level of Ang II and COX-2 mRNA transcription were detected by RT-PCR. The expression level of Ang II was detected by ELISA. The expression level of COX-2 protein was detected by Western blot and immunohistochemical assay.

RESULTSCompared with the blank control group, except the mRNA expression of Ang II at week 4, the mRNA and protein expression of Ang II and COX-2 obviously increased at week 4 and 6 in the model group (P < 0.01, P < 0.05). The COX-2 protein expression at week 4 was obviously lower in the high and moderate dose CQL groups than in the model group and the low dose CQL group (P < 0.05); the average integral of optical density value was obviously lower in the positive control group than in the model group. Except the mRNA expression of Ang II in the high dose CQL group at week 6, the mRNA and protein expression of Ang II obviously decreased in the positive control group and each dose CQL group (P < 0.01, P < 0.05). Of them, the effects were better in the high and moderate dose CQL groups than in the positive control group and the low dose CQL group (P < 0.05, P < 0.01). Besides, the mRNA expression of COX-2, the average integral of optical density value were obviously lower in the positive control group and each dose CQL group than in the model group (P < 0.05). The protein expression of COX-2 was obviously lower in the high and moderate dose CQL groups than in the model group (P < 0.05). Of them, the mRNA expression of COX-2 was better in the moderate dose CQL group than in the positive control group (P < 0.05); the protein expression of COX-2 was better in the high dose CQL group than in the low dose CQL group (P < 0.05).

CONCLUSIONCQL was capable of lowering the expression level of Ang II, COX-2 mRNA transcription and protein expression, thus suppressing the inflammatory pathological injury of the renal tissue.

OBJECTIVETo investigate the effect of compound qingqin liquid (CQL) on Toll-like receptor 2 (TLR2) and toll-like receptor 4 (TLR4) in rats with urate nephropathy, and to explore its renal protection mechanism.

METHODSTotally 55 SD rats were randomly divided into 5 groups, i.e., the normal control group (n =5), the model group (n =10), the positive drug group (n=10), and the high-, medium-, low-dose CQL groups (n=10) respectively. The urate nephropathy model was induced by intragastrically administering adenine and feeding yeast. Distilled water was intragastrically administered at the daily dose of 10 mL/kg to rats in the normal control group and the model group. Allopurinol was intragastrically administered at the daily dose of 9.33 mg/kg to rats in the positive control group. CQL was intragastrically administered at the daily dose of 3.77, 1.89, 0.94 g/kg to rats in the high-, medium-, and low-dose CQL groups. Rats of each group were executed in batches at the 4th and 6th week respectively. Their kidney tissues were taken out to determine the mRNA transcription level of TLR2 and TLR4 by reverse transcription-polymerase chain reaction (RT-PCR). The protein expression level of TLR2 and TLR4 were determined by Western blot. The protein expression level of TLR4 was also detected by immunohistochemical assay.

RESULTSAt week 4 and 6, the protein expression of TLR2 and TLR4 as well as the mRNA transcription of TLR4 increased in the model group, when compared with the control group (P < 0.05, P < 0.01). Compared with the model group, there was no statistical difference in the transcription level of TLR2 mRNA or TLR4 mRNA among the 3 CQL groups (P > 0.05) at week 4 and 6. Additionally, at week 6, the protein expression of TLR4 and TLR2 could be reduced by CQL (P < 0.05, P < 0.01).

CONCLUSIONCQL might protect kidney tissue against inflammatory injury by inhibiting the protein expression levels of TLR2 and TLR4.

OBJECTIVETo investigate the reversing effect of Bcl-XL small interfering RNA (siRNA) on the acquired resistance to tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) in human colon cancer.

METHODSHuman colon cancer cells DLD1-TRAIL/R, with acquired resistance to TRAIL, were firstly transfected with Bcl-XL siRNA for 24 h followed by the treatment of TRAIL protein. The survival rate of DLD1-TRAIL/R cells was assessed by FACS analysis and cell number counting, respectively, and activation of its apoptotic signaling was evaluated by Western blot.

RESULTSBcl-XL siRNA effectively downregulated the expression of Bcl-XL protein and reversed the acquired resistance to TRAIL in DLD1-TRAIL/R cells. After combination treatment of Bcl-XL siRNA and TRAIL protein, the apoptotic rate of DLD1-TRAIL/R cells was more than 50% and survival rate was less than 40%, whereas there was no effect on the survival of DLD1-TRAIL/R cells after treatment with control treatment or TRAIL protein treatment alone (P < 0.05). Western blot analysis demonstrated that caspase-8, caspase-9, Bid, caspase-3, and poly (ADP-ribose) polymerase (PARP) were obviously activated after combination treatment with Bcl-XL siRNA and TRAIL protein, and the release of cytochrome C was also significantly increased.

CONCLUSIONBcl-XL siRNA can effectively reverse the acquired resistance to TRAIL in human colon cancer cells, suggesting that it might be a new strategy for overcoming the resistance in cancer therapy.

OBJECTIVETo study the activity, protein and gene expression of renal HK-ATPase (HKA) in rats subchronic exposed to trimethyltin chloride (TMT).

METHODSIn subchronic toxic test (14-week), 55 female SD rats (age, 6 weeks) were divided randomly into 5 groups: control, low, medium, high and super high dosage, respectively, which drank water with TMT of 0, 8.20, 32.81, 131.25 and 262.50 microg x kg(-1) x d(-1) for 14 weeks. Then serum K+ levels were measured; the activities of HK-ATPase (HKA) in kidneys were detected by the method of determinated phosphorus content; Western Blot assay and real-time PCR were used to exam the protein and mRNA expression levels of HKA in kidneys, respectively.

RESULTSThe serum K+ level in super-high dosage group was (5.6 +/- 0.4) mmol/L, which was significantly lower than that [(6.9 +/- 0.3) mmol/L] in control group (P < 0.01). The HKA enzymatic activity of kidneys in low and super high dosage groups was 4.50 +/- 1.45 and 4.55 +/- 0.72 micromolPi x mg prot(-1)h(-1), respectively, which were significantly lower than that (6.55 +/- 0.77 micromol Pi x mg prot(-1) h(-1)) in control group (P < 0.05).

CONCLUSIONWhen rats were exposed subchronic to TMT, the renal HKA activity could reduce, but the expression levels of HKA protein and mRNA did not decrease.

OBJECTIVETo evaluate the safety, feasibility indications, prognosis and follow-up of laparoscopic distal pancreatectomy.

METHODSRetrospective study was employed on 10 patients collected from Feb. to Oct. 2005 with diagnosis of masses located at pancreatic body/tail. The mean age was 43 years and ratio between male and female was 1:9. Preoperative diagnosis: nine patients with cystic lesion located at pancreatic body and tail, one patient with pancreatic endocrine tumor with liver metastasis, which located at pancreatic tail. The mean size of the tumor was 4.0 cm. All patients received adjuvant examinations including CT contrast scan, abdominal ultrasound or endoscopic ultrasound. The serum levels of tumor markers (including CA19-9, CA242, CA50 and CEA) of the patients were all normal.

RESULTSAll patients received distal pancreatectomy by laparoscope successfully. Among them, seven procedures were spleen-preserved and three with splenectomy. Mean operative time was 228 +/- 26 min, and mean blood lose volume was 173 +/- 100 ml. One patient suffered with pancreatic fistula after operation but was successfully managed by conservative therapy in one month, pancreatic pseudocyst was detected in one patient and disappeared spontaneously in one month, no other morbidity occurred. The postoperative hospital stay was 12 - 16 d (mean, 13.5 d). The serum glucoses of 10 patients after operation were normal. The mean time of follow-up was 8 months (2 - 22 months). During the follow-up, nine patients with benign cystic lesions did not relapse. And the other one patient with malignant metastasis kept stable, not recurrence was detected in one year after operation.

CONCLUSIONSLaparoscopic distal pancreatectomy was safe and feasible for benign cystic tumors located at the body or tail of the pancreas.

OBJECTIVETo investigate the curative effect of antiphlogistic agent series on treating chronic nonbacterial prostatitis (CNP).

METHODSOne hundred and sixty patients were randomized into 4 groups for an 8-week clinical observation: group A (oral antiphlogistic medicinal granules only), group B (oral antiphlogistic medicinal granules + retention enema), group C (oral antiphlogistic medicinal granules + rectal), and group D (antiphlogistic medicinal granules + rectally + hip bath). Single blind trials were employed.

RESULTSThe curative rates of the 4 groups were 37.5%, 57.5%, 52.5% and 82.5% respectively, while the total efficacy rates were 42.5%, 82.5%, 77.5% and 92.5% respectively. Compared with groups A, B and C, the curative rate of group D was significantly higher (P < 0.05). The difference in efficacy rates was slight between groups B and D (P < 0.05), but significant between groups A and C (P < 0.05).

CONCLUSIONSCombined treatment therapy can improve the effect of CNP treatment and clear away heat and toxic material. The antiphlogistic agent series, with the effect of motivating blood circulation and removing blood stasis, turned out to be an effective traditional Chinese medicine in treating CNP.

OBJECTIVE: To analyze the detection rate of the inferior pyloric artery (IPA) in patients with gastric cancer by computed tomography arteriography (CTA). MATERIALS AND METHODS: Fifty-four patients (48 males and 6 females; mean age, 59.0 ± 1.5 years) who had undergone radical gastrectomy for gastric cancer from September 2016 to July 2017 at our institution were recruited prospectively. Patients underwent abdominal contrast-enhanced CT scans and CTA imaging reconstruction before the operation. The origin of the IPA in all cases was determined by a radiologist based on CTA images and verified by the surgeon. The accuracy of CTA in diagnosing the origin of the IPA was calculated. Dominant vessels of the origin were analyzed. RESULTS: IPAs were detected by CTA in 51 patients (94.4%). Among these, IPAs originated from the right gastroepiploic artery (RGEA) (24 cases), the gastroduodenal artery (GDA) (4 cases), and the anterior superior pancreaticoduodenal artery (ASPDA) (20 cases). In the remaining 3 cases, the IPAs contained two branches originating from the RGEA and ASPDA, respectively. During surgery, in 2 (3.7%) of the 54 cases of gastric cancer, IPAs could not be detected; the IPAs originated from the RGEA (22 cases), GDA (5 cases), and ASPDA (24 cases). One case had an IPA originating from both the RGEA and the GDA. Finally, the accuracy of CTA in diagnosing the origin artery of the IPA was 85.2% (46/54). CONCLUSION: CTA can detect the origin of the IPA accurately, which can aid surgeons while performing pylorus-preserving operations.
