OBJECTIVETo evaluate and compare the effect of naso-intestinal tube decompression and octreotide in conservative management of early post-operative inflammatory ileus (EPII).

METHODSFrom March 2005 to January 2009, forty-five patients diagnosed with EPII, who failed to improve with conventional conservative management including nasogastric tube decompression, were enrolled in this study. All patients were prospectively nonrandomized into naso-intestinal tube group (n = 23) or Octreotide group (n = 22). The outcomes were compared between nasogastric tube, naso-intestinal tube and Octreotide groups.

RESULTSAll the forty-five patients with EPII refractory to conservative management with nasogastric decompression were treated successfully with the naso-intestinal tube decompression or octreotide in 3-12 days. Compared with the Octreotide group, the first passage of flatus was earlier [(4.7 +/- 1.9) d vs (6.7 +/- 1.6) d] and abdominal circumference recovered faster [(90.4 +/- 2.0)% vs (95.1 +/- 1.3)%] in the naso-intestinal tube group (P < 0.05). But the volume of cumulative and daily gastrointestinal decompression were more in naso-intestinal tube group than those in Octreotide group [(4037 +/- 1155) ml vs (3316 +/- 1038) ml; (890 +/- 181) ml vs (492 +/- 83) ml; P < 0.05].

CONCLUSIONSPatients with EPII could be safely and effectively managed by naso-intestinal tube decompression or octreotide. It is possible for those patients to avoid second laparotomy. Naso-intestinal tube decompression and octreotide are associated with faster recovery and less fluid loss respectively.

A full-length cDNA encoding a MYB-related regulatory gene was isolated from a cDNA library prepared from mRNAs of the red line callus of S. medusa by TD-PCR. The cDNA, designated SmP, is 969 nucleotides long and has an open reading frame of 771 bp with a deduced amino acid sequence of 256 residues. The putative protein of SmP has two typical conversed R2R3-Myb DNA-binding domains in N-terminal and displays a rather high degree of similarity to OsMYB from rice and LBMI from tobacco, showing 73% and 70% identity within the DNA-binding domains. However, the C-terminal domain of the SmP protein does not show obvious similarity to any other known protein sequence. It is rich in hydrophilic amino acids, especially in serine residues (18.38%), partly organized in homopolymeric stretches, a feature often found in activation domain of transcription factors.

OBJECTIVETo discuss the individual operation standard and safety on the deep puncturing at Tianshu (ST 25).

METHODSThe deep insertion through the peritoneum about 1-2 millimeter was taken as individual standard depth at Tianshu (ST 25) for 39 patients. Using CT cross-section scanning and image surveying, the regression analysis was conducted on the impacts of abdominal circumference (AC,cm) to the peritoneum depth.

RESULTSIt was concluded the formula for calculating the satisfactory depth of individual insertion at Tianshu (ST 25), depth = -0.562 + 0.045 x AC.

CONCLUSIONThe depth of insertion, 1-2 millimeter through peritoneum at Tianshu (ST 25) is safe and feasible in acupuncture treatment, which can be used significantly as the reference and guidance for the assessment of clinical operation and safety on the deep puncturing of the other acupoints on the abdominal region.

Objective To investigate the change of the basic fibroblast growth factor(bFGF) leve in human detrusor muscle(DM)in bladder outlet obstruction(BOO)due to benign prostatic hyperplasia(BPH)and its implication.Methods Fifty-four patients with BPH were divided into two groups:the obstructive DM stability and instability groups;and 15 men with bladder tumor who underwent operation in the same period were enrolled in the control group.The bFGF mRNA level in DM was measured by reverse transcription and polymerase chain reaction(RT-PCR)and the bFGF protein level was measured by immunohistochemical staining method.Results The bFGF-mRNA expression level of bladder smooth muscle cells was significantly lower in the control group than that in the obstructive DM stability and instability groups(all P＜0.05),but there was no significant difference between the obstructive DM stability and instability groups(P＞0.05). Conclusions The expression level of bFGF mRNA in bladder DM is elevated in BOO due to BPH,but there is little or no correlation between the increased expression of bFGF mRNA and detrusor muscle instability.

Objective To investigate the effect of green light laser in complex posterior urethral stricture after surgical treatment of benign prostatic hyperplasia (BPH).Methods Green light laser was applied in treating 20 cases of complex iatrogenic posterior urethral stricture.Of these cases,12 had false passages,5 had more than 2 strictures and 5 had concurrently urethratresia.The scar tissues were transure- thrally vaporized and resected.The in-dwelling urethral catheter time was 1-2 months after operation. Results All the patients were initially cured without serious complications.The mean operative time was 39 rain (range,30-65 min).During the follow-up of 2-10 months,1 case had mild incontinence:another case (Q_(max)＜9ml/s 2 weeks after surgery) got satisfactory results(Q_(max)＞15ml/s)after the scheduled urethral dilatation.The other 18 cases were treated successfully and voided fluently with postoperative Q_(max)＞15ml/s in all.Conclusions It is suggested that transurethral green light laser procedure is not only safe and ef- fective,but also simple and minimally iuvasive for complex posterior urethral stricture following surgical treat- ment of BPH.

Objective To report a large family with an autosomal dominant dementia associated with mutation in the prion protein gene(PRNP)and the detailed clinical,neuroimaging and pathological manifestations.Methods Two patients from a large family of dementia were admitted to our ward and the data of their medical history,physical examination,video electroenceplialogram,neuroimaging were colleted.A sterotactic biopsy of the right frontal lobe of the proband was done.After the informed consent from the family members obtained,the genomic DNA was extracted from peripheral blood leucocytes of 5 persons followed by in,vitro amplification using polymerase chain reaction(PCR).The PCR products were directly sequenced by Sanger method.PRNP gene sequence was also examined in 150 normal Chinese to exclude single nueleotide polymorphism.Results A missense mutation of PRNP gene in 5 farnily members was detected,resulting in Gll4V mutation in the prion protein,with M/M genotype of eodon 129.This mutation was not detected in 150 normal Chinese.The proband was diagnosed as inherited prion disease by her clinical features,including neuropsychiatrie disturbances and progressive dementia,and manifestations of neuroimaging,EEG,neuropathology and PRNP gene mutation.Conclusion The first autosomal dominant pedigree of family prion disease is found in China with G114V mutation in PRNP gene which may lead to the prion disease directly.

OBJECTIVETo investigate the effects of lentivirus-mediated RNA interference targeting vascular endothelial growth factor receptor 1 (VEGFR1) gene on the proliferation, migration and apoptosis of leukemic cell line U937.

METHODSShort hairpin RNAs (shRNA) targeting VEGFR-1 was synthesized and cloned into pRNAT-U6.2 lentiviral vector. The expression vectors were transfected into 293T cell line to produce packaged lentivirus. After infected with the packaged lentivirus, the expression of VEGFR-1 gene of U937 cells at mRNA and protein level was detected by real-time PCR and Western blot. VEGF production by the cells was determined by ELISA. Cell proliferation and survival under regular culture and in the presence of cytarabine (Ara-C) was determined by CCK-8 assay. Migration assays were performed by 5 µm pore transwell inserts.

RESULTSThe lentiviral shRNA vector targeting VEGFR-1 was successfully constructed and transfected into U937 cells. The shRNA vector effectively inhibited the expression of VEGFR-1 gene in U937 cell line at mRNA and protein levels. As compared to that of the control, the proliferation rate of U937-shVEGFR-1 cells reduced; The VEGF production and migrated cell number of U937-shVEGFR-1 cells decreased dramatically. After treated with Ara-C, the inhibition rate and apoptotic rate of U937-shVEGFR-1 cells increased significantly. The number of migrated cells in the KD group under regular culture and in the presence of VEGF was markedly lower than that in the NC group and CON group. Bevacizumab could decrease the number of migrated cells in the NC group and CON group, but could not in the KD group.

CONCLUSIONSLentivirus-mediated RNA interference targeting VEGFR1 gene reduces the proliferation, migration of U937 cell line and enhances its sensitivity to Ara-C.

OBJECTIVETo study the prevalence rate of hypertension and the risk factors in Guangxi Hei Yi Zhuang population.

METHODSA total of 1068 people of Hei Yi Zhuang nationality aged 20 and over were surveyed. Blood pressure, height, weight, serum lipid and apolipoprotein levels were measured ,and both body surface areas and body mass index were calculated. Results were compared with those in 933 people of Han nationality living in the same district.

RESULTSThe prevalence rates of hypertension in Hei Yi Zhuang population were significantly higher than that in Han population (25.2% vs. 17.3%, P < 0.001) ,as well as the isolated systolic hypertension (12.5% vs. 3.9%, P < 0.001). The mean levels of systolic pressure and pulse pressure in Hei Yi Zhuang population were significantly higher than those in Han population (125.20 +/- 18.62 vs. 121.88 +/- 15.99 mm Hg, P < 0.001 and 48.64 +/- 14.75 vs. 44.98 +/- 11.12 mm Hg, P <.001; respectively). The prevalence rate of hypertension in Hei Yi Zhuang population was positively correlated with triglyceride, sex and age whereas the prevalence rate of hypertension in Han population was positively correlated with total cholesterol, sex, age, and alcohol consumption. Rates of awareness on hypertension in Hei Yi Zhuang and Han population were 8.6% vs. 21.1% (P <.001), patients with treatment rate of established hypertension were 4.5 vs. 15.5 (P < 0.001) with the control rates as 1.9 vs. 10.6 (P < 0.001).

CONCLUSIONThe prevalence rate of hypertension in Guangxi Hei Yi Zhuang population was significantly higher than that in Han ethnic group. The causes of high prevalence rate of hypertension might be ascribed to special geographical surroundings, unhealthy life style, high sodium intake, low education, and possibly genetic factors. The rates on awareness, treatment and control of hypertension were still under satisfaction.
