Objective To explore the clinical features of pulmonary tuberculosis complicated with DM and related factors. Method The manifestations of 87 newly diagnosed PTB patients with type 2 DM(DM-PTB group) at two hospitals in Tianjin during October 2003 to October 2004 were compared to 88 PTB patients without DM who were randomly choosen from the same hosipital.The factors related to sputum-positive TB or cavity were explored through unconditional logistic regression model. Results DM-PTB patients showed significanly lower frequencies of cough(66.7% vs 83.0%),toxicity symptoms(37.9% vs 62.5%) and haemoptysis(16.1% vs 33.0%) than those of PTB group.Positive-sputum(63.2% vs 34.1%),cavity(56.3% vs 13.6%),wide lesions and bilateral lesions on chest radiographs was more common in DM-PTB group than in PTB one.Introversion(OR=1.582, 95%CI:1.063 ～2.355),type 2 DM(OR =2.186,95% CI:1.082 ~4.420)and cavity(OR =2.793,95% CI:1.308 ～5.964)were factors independently associated with positive-sputum TB.The factors related to cavity included diabetes(OR=14.199,95%CI:5.376~ 37.501),cough,postive sputum and lore-up lobe lesion.Conclusion This study confirmed that clinical manifestations and chest radiographs of PTB patients complicated with type 2 DM significantly departed from the typical presentation.Type 2 DM seems to have a negative effect on postive-sputum and cavity.So it should be alarmed that DM-PTB patients who tend to have untypical clinical symptom and higher rate of positive sputum become the reservoirs of infection to cause the transmission of TB.

Objective To investigate the clinicopathological features of hepatitis B virus-associated glomerulonephritis(HBV-GN) in children.Methods Clinical and pathological features were analyzed and correlated in 73 cases with renal biopsy-confirmed(HBV-GN).Sixty-six boys and 7 girls aged from 1 to 14 years old were included in this study,accounting for 14.4% in children under-(going) renal biopsy in the same period.Results Nephrotic syndrome(NS) was the prodominant clinical manifestation(53/73,72.6%),followed by glomerulonephritis(15/73,20.5%) and hematuria with proteinuria(5/73,6.9%).Serologic markers of HBV were found in all cases.Among them,55 cases(75%) were positive for hepatitis B surface antigen(HBsAg),hepatitis B e antigen(HBeAg) and anti-hepatitis B core(anti-HBc),14 cases(19.2%)positive for HBsAg,anti-HBe and anti-HBc,2 cases positive for HBsAg and anti-HBc,1 child positive for HBsAg and HBeAg,and another only positive for anti-HBc.The most common pathological type of HBV-GN was membranous nephropathy(MN),which was found in 69 cases(94.5%),followed by membranoproliferative glomerulonephritis(MPGN) and mesangial proliferative glomerulonephritis(MsPGN),2 cases(2.7%),respectively.All cases with NS presented themselves with MN.The pathological grades were significantly correlated with clinical manifestations through double trend analysis(?~2=5.22 P=0.022).Conclusions MN is predominant in childhood HBV-GN,which mainly presented with NS.Their clinical patterns are somewhat correlated with pathological grades.

Objective To investigate the extracellular regulated protein kinases (ERKs) pathway of hepatitis B virus(HBV) X protein(HBx) on glomerular mesangial cell(GMC) proliferation of rat and tumor necrosis factor(TNF)-? expression.Methods The HBV X gene was amplified by polymerase chain reaction(PCR),inserted into the eukaryotic expression vector PCI-neo and confirmed by restrict endonuclease digestion and sequence analysis.PCI-neo contained HBV X gene (PCI-neo-X) was transfected into cultured GMC via liposome.GMC proliferation,TNF-? and its mRNA expression were investigated in the condition of with or without U0126 in the culture media.HBx,ERK1/2 and phosphorynated-ERK1/2 (p-ERK1/2) expression in GMC were assessed by Western blot.TNF-? mRNA expression was assessed by semi-quantitative reverse transcriptase-PCR (RT-PCR).TNF-? level in supernatants was measured by enzymelinked immunosorbent assay(ELISA).GMC proliferation was assessed by methyl thiazolyl tetrazolium(MTT).Results HBx expression was found in transfected GMC,and became prominent at 36 and 48 hours after transfection whether with or without U0126 in culture media.TNF-? mRNA expression was significantly decreased in U0126 group compared with U0126-free group.TNF-? levels in supernatants in PCI-neo-X transfection without U0126 group were (189.0?18.1) ng/L at 36 hours and (172.3?24.3) ng/L at 48 hours after transfection,respectively.In contrast,TNF-? levels in supernatants with U0126 were (65.6?11.6) ng/L and (84.0?24.6) ng/L,respectively.The TNF-? le-vels in the latter groups were significantly lower than the formers (Pa

Objective To evaluate the clinical value of laparoscopic renalcyst unroofing as compared with open surgery.Methods The clinical data of 30 cases(group A) receiving glaparoscopic renalcyst unroofing from February 2002 to March 2005 and 15 cases(group B) receiving open renalcyst unroofing from February 2002 to February 2004 were retrospectively analyzed.The rating of depression and anxiety before operation,operating time,amount of bleeding during operation,recovery of intestinal function after operation,ambulation and normal activities after operation,the time of using intravenous after operation,the times of using analgesic after operation,the operation cost,total cost of hospitalization,the hospital stay and complications were compared between group A and group B.Results In group A,the amount of bleeding during renalcyst unroofing operation,the recovery of intestinal function after operation,ambulation after operation,the hospital stay,the resume of normal activities after operation and the occurrence of complications the time of using intravenous after operation,the times of using analgesic after operation were all better than those in group B(P

Objective To evaluate the effectiveness of spiral stone dislodger combined with pneumatic lithotriptor under ureteroscopy for managing upper ureteral stones. Methods 106 patients with upper ureteral stones with spiral stone dislodger combined with pneumatic lithotriptor under ureteroscopy were treated. The transverse diameter of the stones was 4～12mm and the vertical length 6～15mm. Results 87.7% (93/106) stones were fragmented for one session of treatment. 8 cases were pushed upward then undergoing extracorporeal shock wave lithotripsy(ESWL) after surgical operations. Operations in 5 cases had to be changed to open surgery,and ureteral perforations happened in 1 case. Conclusion Successful entrance of the uretersocop is a prerequisite for crushing the stone,appropriate fixation of the stone is the key to their crushing,spiral stone dislodger is an effective means of fixing ureteral stones.

Objective To assess the cause of iatrogentic urethral stricture,prevention methods.Methods A total of 21 cases of iatrogentic urethral stricture patients were retrospectively analyzed. Results 2 cases of corpus glandulare prostatae extraction on ospectinis,2 cases of urethrolithotomy, 12 cases of transurethral resection of the prostate foe the treatment of symptomatic BPH, 5 cases of exelcymosic UCL all gained urethral sounding and urethra sliver and electrotomy. Conclusion Iatrogentic urethral stricutre can be prevented by iatrogentic urethral catheterization operation technical,reconstruction the time size quality of urethral catheterization, using intravenous. By urethral sounding and intracavitary operation,iatrogentic urethral stricture all gained satisfaction.
