Objective To find out about the risk factors and prevention and treatment measures for complication with hospital infection in patients with primary nephrotic syndrome. Methods An analysis was conducted by means of retrogressive survey of the relevant clinical data on 146 cases of patients with primary nephrotic syndrome. Results The rate of hospital infection in patients with primary nephrotic syndrome reached 35 6%, with the respiratory tract being the main infected site(46 4%) and the urinary tract being the next major infected site(17 9%); the rate of infection is related to such factors as length of stay(P

Objective To investigate the changes of coagulation function in the neonates patients with gastrointestinal dysfunction and chnical significance. Methods Forty neonates with gastrointestinal dysfunction were included, which were divided into three groups according to diagnosis criterion of gastrointestinal dysfunction: early group, medium group and late group. Coagulation function was tested and neonatal critical illness score(NCIS) was done. Forty normal neonates were selected as control group. The difference of coagulation function among all groups was observed, and the relationship between coagulation function and NCIS were evaluated. Results Compared with control group, the indexs of coagulation function of early group was no statistical difference (P>0.05), however the result between medium group and late group was significantly difference (P<0.05). The difference of coagulation function between medium group and late group was also significant (P<0.05), the lower NCIS was, the more serious the gastrointestinal function was. Conclusions The more serious the gastrointestinal dysfunction is, the poorer the coagulation function is and the lower the NCIS is, which suggest coagulation function should be monitored in neonates with gastrointestinal dysfunction, and early intervention should be done accordingly.

Objective To investigate the clinical effect of laparoscopic radical hysterectomy in the treatment of early-stage endometrial cancer.Methods A total of 60 consecutive patients preoperatively diagnosed as having stage Ⅰ or Ⅱ endometrial cancer from August 1998 to December 2004 was divided into two groups,receiving either laparoscopic(Laparoscopic Group) or open radical hysterectomy(Open Group).According to the involvement of the muscular layer,whether or not a pelvic lymphadenectomy was required was determined.Perioperative parameters and survival time were prospectively studied.Results As compared with the Open Group,the Laparoscopic Group presented a longer operation time(247.8?77.8 min vs 196.6?63.7 min;t=2.789,P=0.007),similar blood loss(265.0?187.6 ml vs 350.0?210.9 ml;t=-1.649,P=0.104),similar number of resected lymph nodes(22.0?5.0 vs 22.8?5.2;t=-0.607,P=0.546),insignificant difference in complication rate (10/30 vs 15/30;?2=1.714,P=0.190),earlier time to first passing flatus(44.3?11.1 min vs 55.2?12.8 min;t=-3.524,P=0.000),and shorter hospital stay(8.7?3.2 d vs 10.2?2.0 d;t=-2.177,P=0.034).The patients in the Laparoscopic Group were followed for 28.6?17.4 months with tumor-free survival.In the Open Group,a follow-up for 28.9?16.6 months found 3 deaths form metastasis or recurrence.Conclusions Laparoscopic radical hysterectomy and pelvic lymphadenectomy may be an alternative for early-stage endometrial carcinoma.

Objective To study on the effectiveness of endoscopy in diagnosing the gallbladder-intestine fistula. Methods The clinical datum of 24 patients with gallbladder-intestine fistula from January 1982 to March 2004 were reviewed and analyzed retrospectively. All patients were examined by endoscopy and confirmed from operation. Results Twenty-one out of 24 patients were finally diagnosed by endoscopy while 3 of them were misdiagnosed. Other examinations among the 24 patients included B ultrasound 11 , computer tomography (CT) 5, and abdominal plain films 7; none of them was finally diagnosed by these measures. Two out of 8 patients were finally diagnosed by barium meal or enema roentgenogram. Conclusion Endoscopy was an important method in diagnosing the gallbladder-intestine fistula. The diagnostic level would be improved if the specific characters of endoscopies in this entity were fully recognized.

Objective:To investigate procalcitonin and C-reactive protein levels in diarrheal patients who underwent irinotecan che-motherapy. Methods:Procalcitonin and C-reactive protein were detected among 85 diarrheal and 63 non-diarrheal patients after irinote-can chemotherapy. Results:According to WHO classification, patients without diarrhea are classified as grade 0, whereas patients with diarrhea can be classified as gradesⅠ-Ⅳ. In grades 0,Ⅰ,Ⅱ,Ⅲ, andⅣpatients, the levels of procalcitonin were 0.29 ± 0.17, 0.30 ± 0.18, 0.36 ± 0.20, 1.24 ± 0.22, and 2.15 ± 0.26 ng/mL on the second day, respectively. However, on the fourth day, the procalcitonin lev-els were 0.28 ± 0.15, 0.30 ± 0.14, 0.34 ± 0.18, 2.00 ± 0.22, and 2.40 ± 0.28 ng/mL, respectively. Moreover, in grades 0,Ⅰ,Ⅱ,Ⅲ, andⅣ, the levels of C-reactive protein were 6.06 ± 1.85, 6.12 ± 1.16, 6.20 ± 1.68, 22.62 ± 4.55, and 31.26 ± 5.23 mg/L on the second day, respectively. On the fourth day, the C-reactive protein levels were 5.80 ± 1.82, 5.94 ± 1.14, 6.15 ± 1.55, 30.52 ± 4.74, and 38.67 ± 5.68 mg/L, respectively. No significant difference was found between the procalcitonin and C-reactive protein levels of stagesⅠandⅡpa-tients (P>0.05), but a significant difference was found between stagesⅠ, andⅡpatients and stagesⅢandⅣpatients (P<0.05). Con-clusion: Monitoring levels of procalcitonin and C-reactive protein may be helpful in the early evaluation of the severity of diarrhea. This process has prognostic effect and can be used to assess whether patients have enterogenous bacterial infection. Monitoring the lev-els of these proteins has certain clinical value and can be used to guide early anti-infection therapy.

BACKGROUND: Up to date, studies concerning capspase 3 inhibitor mainly focus on peptide/non-peptide compounds synthesis and detection. Few reports addressing inhibits chondrocytes apoptosis using silenced caspase 3 gene. OBJECTIVE: To inhibit apoptosis of chondrocytes by blocking the apoptotic cascade reaction, gene silencing of caspase 3, and transduction of caspase 3 siRNA into chondrocytes with lentivirus vector.DESIGN, TIME AND SETTING: A single sample observation was performed at the Institute of Traumatic Surgery, Guangzhou Red Cross Hospital, Medical College of Jinan University from June 2008 to June 2009.MATERIALS: Chondrocytes were harvested from SD rats, and caspase 3 shRNA plasimid was constructed by our laboratory.METHODS: Rattus caspase 3 siRNA was synthesized and cloned into pSIH1-H1-copGFP plasmid. pSIH1-H1-copGFP-caspase 3 siRNA lentivirus was generated in 293TN cells by pPACKH1~(TM) Lentivector Packaging Kit and transducted into chondrocytes of rats.MAIN OUTCOME MEASURES: After the lentivirus was transducted into chondrocytes, the caspase 3 mRNA was tested by RT-PCR and the caspase 3 protein was tested by Western blot. Both the transducted cells and untransducted cells were induced apoptosis by tumor necrosis factor α (TNF-α). Cell apoptosis was assessed by flow cytometry, Annevin V/PI.RESULTS: The transduction rate of caspase 3 siRNA was about 90% by lentivirus vector. The expression of caspase 3 mRNA and caspase 3 protein in transducted chondrocytes was lower than the normal chondrocytes (P < 0.01). When the cells induced apoptosis by TNF-α, the apoptosis rate of the negative siRNA- chondrocytes was 7 times higher than that of caspase 3 siRNA-chondrocytes.CONCLUSION: The caspase 3 siRNA could inhibit caspase 3 expression and decrease drug-induced apoptosis of the chondrocytes.

Objective To investigate the effect of heme oxygenase-1 (HO-1) on hypoxia-reoxygenation (H/R) injury in cultured neonatal rat cardiomyocytes. Methods Primary cultured neonatal rat cardiomyocytes were randomly divided into4 groups: Ⅰ control group (group C), Ⅱ H/R group, Ⅲ hemin group and Ⅳ hemin+zinc protoporphyrin (ZnPP) group. In group H/R, the cardiomyocytes were exposed to 2 h of hypoxia followed by 6 h of reoxygenation. Hemin was added to the culture medium with a final concentration of 20 μmol/L 24 h before hypoxia and immediately before hypoxia in group hemin. Hemin and ZnPP were added to the culture medium with final concentrations of 20 μmol/L 24 h before hypoxia and immediately before hypoxia in group Henin + ZnPP. The cells were incubated in 35 mm culture dishes (2 ml in each dish) and 50 ml culture flasks (3 ml in each flask)(45 dishes and 3 flasks in each group). The HO-1 expression, cell survival rate, LDH activity, malondialdehyde (MDA) level and superoxide dismutase (SOD) activity were detected after the end of reoxygenation. Results Compared with group C, the LDH activity, MDA level and HO-1 expression were significantly increased, while the cell survival rate and SOD activity decreased in the other three groups ( P ＜ 0.05). Compared with group H/R,the LDH activity and MDA level were significantly decreased, while the HO-1 expression, cell survival rate and SOD activity increased in group hemin ( P ＜ 0.05 ), but no significant change was found in group hemin + ZnPP (P ＞0.05). H/R injury was obvious in group H/R and hemin + ZnPP, but was significantly attenuated in group hemin. Conclusion HO-1 can protect cardiomyocytes against H/R injury in neonatal rats.
