Objective To explore the mechanism of tripterygium wilfordii hook f(TWHF)for Henoch-Schonlein purpura nephritis(HSPN,nephrotic type)in children.Methods All the children with HSPN(nephrotic type)were divided into 3 groups casually.Method of radioactive pairs conjugating analysis was used to determine the numbers of glucocorticoid(GC)receptors(GCRs).Results were statistically analysed respectively.Results GCRs tested in all the patients with HSPN(nephrotic type)before treatment were statistically lower than those in control group of normal children;GCRs in all the patients tested after 1 week treatment with GC were lower than before treatment.Three weeks later,GCRs in patients treated with TWHF increased much higher than them without TWHF.Following up the recurring times of all the patients 3 months to 5 years,they were much more in patients treated without TWHF treatment than in patients treated with it.Conclusions TWHF treatment on HSPN(nephrotic type)is obviously effective.It can not only decrease the dosage of GC,but decrease the recurring times.One of the mechanism may be TWHF can resist the down-regulation GC to GCR,and enhance the effect of GC.

After brief introduction of FISH (fluorescence in situ hybridization),it was discussed of the FISH's application status in research on biological nitrogen removal in recent years. Base on the FISH technology,Characterization of the community in biological reactor could be showed exactly,but more research should be carried out for the study on the effluence on microbial community composition,which was caused by changing operating parameter of biological reactors on the microbial community composition,such as SRT,DO and C/N ratio.The combination of FISH and other methods such as PCR-DGGE and 16S rRNA/rDNA will led to the identification of the microbial community which response for the nitrogen-removal in wastewater treatment plant.

OBJECTIVESTo introduce the method and experience of three-piece inflatable penile prosthesis for treatment of erectile dysfunction (ED).

METHODSBoth AMS700CX/CXM and MENTOR ALPHA I three-piece inflatable prosthesis were used for 48 cases of ED.

RESULTSThere were no rejection, mechanical problems, urethral injury and penile skin necrosis after surgery. All patients had satisfaction of sexual life. Only one case had trauma of tunica albuginea (2.08%) and the implantation had to be cancelled. There were 2 cases of post-operative infection (4.17%), 10 cases of prepuce edema(20.8%), 8 cases of penile pain(16.67%). The effective rate was 97.9% and satisfaction rate was almost 100%.

CONCLUSIONSThree-piece inflatable penile prosthesis was more compatible to human physiology. It is natural, easy to hide and use, and it caused little trauma in surgery with high rate of successful implantation and patient satisfaction. It was indicated for all kinds of ED, especially suitable for refractory and drug incurable ED patients.

OBJECTIVETo study the rehabilitation effects ergometry on COPD patients.

METHODSThirty COPD out-patients in our Hospital were randomly divided into 2 groups. Rehabilitation group, 15 patients, performed leg ergometry exercise of 80% peak Watt x 30min/d x 3d/w x 12w. Another 15 patients were control group without exercise. All patients received conventional therapy. Pulmonary function testing (PFT), cardiopulmonary exercise testing (CPET), arterial blood gas analysis (ABG), Borg and CAT sores were done at both baseline and 12 w.

RESULTSThere was no statistically difference in lung function testing, blood gas analysis and cardiopulmonary exercise test when pre- exercises between 2 sub-groups. The IC, peak VO2 and peak, W of rehabilitation group significantly increased (P < 0.05); and Borg and CAT.scores significantly decreased (P < 0.05) from baseline; and other PFT and ABG did not change (P > 0.05). While there was no difference in control group (P > 0.05).

CONCLUSIONLeg submaximal ergometry rehabilitation improves health condition and ameliorate dyspnea symptoms in COPD patients.

OBJECTIVETo observe the changes in serum contents of interleukin-6 (IL-6) and interleukin-10 (IL-10) in patients with severe burn injury, and to investigate their relation with occurrence of sepsis and prognosis of patients.

METHODSOne-hundred and sixty adult patients admitted into our hospital (1.0 ± 6.0) h after injury during March 2007 to March 2011 with massive and severe burns were enrolled in the investigation. Patients were divided into non-sepsis group (NS, n = 112), sepsis-survival group (SS, n = 36), and sepsis-deceased group (SD, n = 12) based on the occurrence of sepsis and death. Sepsis occurred on post burn day (PBD) 9 ± 5 in patients in the latter two groups. Patients died on PBD 18 ± 4 in SD group. Twenty healthy adult volunteers were chosen as healthy control group (HC). The age of subjects for observation among four groups, and total burn area and full-thickness burn area of patients among NS, SS, and SD groups were compared. Serum was isolated from blood samples collected from each patient every day from day of admission till PBD 20 to determine the contents of IL-6 and IL-10 by ELISA, and the same determinations were done in HC group. Data of trial subjects were processed with one-way analysis of variance. Data of IL-6 and IL-10 contents were processed with analysis of variance of repeated measure data and SNK method (q test).

RESULTS(1) There was no significant statistical difference among four groups in age (F = 2.090, P > 0.05). Total burn areas of patients in SS and SD groups were significantly larger than that in NS group (q test, with P values both below 0.05), and total burn area of patients in SD group was obviously larger than that in SS group (q test, P < 0.05). Full-thickness burn areas of patients in SS and SD groups were significantly larger than that in NS group (q test, with P values both below 0.05). (2) Serum contents of IL-6 of patients in NS, SS, and SD groups from PBD 1 to 20 were obviously higher than that of volunteers in HC group. There was no significant statistical difference among NS, SS, and SD groups in serum contents of IL-6 from PBD 1 to 7 (with F value from 0.188 to 2.897, P values all above 0.05). Serum content of IL-6 of patients in NS group decreased from PBD 4. Serum content of IL-6 of patients in SS group decreased gradually from PBD 13, but that in SD group increased continuously at the same time points. Serum contents of IL-6 of patients in NS group [(262 ± 25) pg/mL on PBD 8] were lower than those in SS group [(287 ± 38) pg/mL on PBD 8, q test, P < 0.05] and SD group [(299 ± 22) pg/mL on PBD 8, q test, P < 0.05] from PBD 8. Serum contents of IL-6 of patients in SS group [(300 ± 33) pg/mL on PBD 13] were obviously lower than those in SD group [(338 ± 22) pg/mL on PBD 13, q test, P < 0.05] from PBD 13. (3) Serum contents of IL-10 of patients in NS, SS, and SD groups were higher than that in HC group at each time point. There was no significant statistical difference among NS, SS, and SD groups in serum contents of IL-6 from PBD 1 to 5 (with F values from 1.802 to 2.538, P values all above 0.05). Serum content of IL-10 of patients in NS group was obviously lower than that of patients in SD group from PBD 6 (q test, P values all below 0.05). On PBD 8, serum content of IL-10 of patients in SS group [(54 ± 19) pg/mL] was obviously lower than that in SD group [(91 ± 23) pg/mL, q test, P < 0.05]. The sum of sensitivity (83.33%, 10/12) and specificity (91.67%, 33/36) minus 1 was maximum when the critical value of IL-10 content was set at 77 pg/mL based on the comparison between SS group and SD group in serum content of IL-10 on PBD 8.

CONCLUSIONSThe occurrence and outcome of sepsis is related to burn area and depth when the patients are in similar age. Serum contents of IL-6 and IL-10 play important roles in the pathogenesis of sepsis after burn. IL-6 content in early stage shall not be used in predicting the prognosis of patients with sepsis. IL-10 continuously higher than 77 pg/mL in early stage forecasts unfavorable prognosis of patient.

OBJECTIVETo investigate the association of MK2 gene with low density lipoprotein cholesterol (LDL-C) and tumor necrosis factor-alpha (TNF-Α) between different gender in Xinjiang Uygur population.

METHODSA total of 350 Uygur males and 595 females were recruited randomly from Hetian area. Two single nucleotide polymorphisms (44890c/t, rs 45514798) in MK2 gene were selected and genotyped by Taqman-PCR in these subjects. All subjects underwent questionnaire-based survey, physical examination, measurement of lipid profiles and plasma TNF-Α determination.

RESULTSAmong the male subjects, the concentration of total cholesterol (TC) [TT vs. CT vs. CC: (4.35±1.20) mmol/L vs. (4.69±1.34) mmol/L vs. (4.83±1.44) mmol/L, P=0.033]and TNF-Α [TT vs.CT vs.CC: (106.63±62.39) ng/dL vs. (128.44±86.15) ng/dL vs. (153.06±82.99) ng/dL, P=0.001]were significantly different in 3 genotypes of 44890c/t. However, the LDL-C levels in TT, CT, and CC genotypes of 44890c/t were not different neither in males nor in females [males: (2.64±1.16) mmol/L vs. (2.81±1.28) mmol/L vs. (3.04±1.32) mmol/L, P>0.05; females: (2.42±1.11) mmol/L vs. (2.36±0.99) mmol/L vs. (2.43±1.05) mmol/L, P>0.05]. None of the allele and genotype frequencies of 44890c/tand rs 45514798 were different between high LDL-C group and control group. Linear regression analysis indicated that body mass index (BMI) (beta=0.089) and TNF-Α (beta=0.092) were significantly associated with LDL-C levels in males (P<0.05), while the age, BMI, and waist/hip ratio with LDL-C levels in females (P<0.05).

CONCLUSIONThe nucleotide polymorphisms (44890c/t and rs 45514798) in MK2 gene may not be associated with LDL-C in both males and females in the Uygur population in Hetian, Xinjiang.

OBJECTIVETo study the clinical and pathological features of drug-induced liver injury (DILI).

METHODSLiver specimens were obtained through needle biopsies from 100 patients with DILI. The histological preparations of the specimens were stained with haematoxylin eosin, several histochemistry methods, and immunohistochemistry stains. The pathological changes of the livers were analyzed together with the patients's clinical data. The patients were divided into two groups, an acute DILI group (n=39) and a chronic DILI group (n=61), based on their clinical courses and histological changes in their livers. In the chronic DILI group, the clinical courses were longer than 6 months and/or fibrosis or cirrhosis occurred in their liver tissues.

RESULTSAmong our cases the leading cause of DILI was Chinese herb medicine, accounting for 21% of the 100 cases; steroids induced cases were 11% of the total. 78% of the patients presented elevated serum transaminases and/or jaundice. The degree of transaminases elevation and the frequency of jaundice happening in the acute group were significantly higher than those in the chronic group (P less than 0.05). The histopathological liver changes in these DILI cases included: (1) necrosis commonly occurred in acinar zone 3, (2) abundant neutrophil and/or eosinophil infiltrations, (3) hepatocytic and/or canalicular cholestasis with little or no inflammation, (4) microvesicular steatosis mixed with macrovesicular steatosis, and (5) presentation of epitheloid cell granuloma. There were no significant differences in liver histopathology between the acute and the chronic DILI groups, except that the fibrosis and the ductular proliferation were different.

CONCLUSIONDILI has become a notable liver disease in mainland China, and the use of Chinese herbal medicine must be improved, standardized and regulated more closely.

OBJECTIVETo explore the etiology, clinical aspects, diagnosis and therapeutic strategies of acute low-tone sensorineural hearing loss (ALHL).

METHODSThirty patients (31 ears) with ALHL were selected for this study. Detailed history collection, otological examination and systematic audiological evaluations were conducted. The hearing tests included pure tone audiometry, acoustic immittance, auditory brainstem response (ABR) and otoacoustic emissions (OAE). All cases received therapeutic trial of corticosteroid for 15 days with 6 to 14 months' following-up.

RESULTSALHL mainly affected young people. Low-tone tinnitus, a sensation of ear fullness and hearing impairment were the frequent complains. Otological examinations showed normal results. Mild to moderate sensorineural hearing loss at low frequencies and type "A" tympanograms were found in all patients. Acoustic stapedial reflexes were elicited in 26 of 31 affected ears, and 14 of them had positive results on the Metz test. ABR responses were normal in all 20 tested ears. In 14 out of 20 ears, TEOAEs were absent and DPOAE grams at low frequencies (0.5, 0.75 kHz) were abnormal on the first visit. After steroid therapy, 24 ears demonstrated complete recovery, but 4 ears showed partial recovery and 3 ears unchanged. The total improvement rate was 90.3%.

CONCLUSIONSALHL patients are clinically characterized by low-tone tinnitus, aural fullness and hearing loss, which mainly involved unilateral ear. Audiological findings indicate a cochlear impairment, which only invades low frequency region. The basic pathological feature may be endolymphatic hydrops involves immune response. Conflicting data exist on whether ALHL is an independent disorder or a subtype of Meniere's disease. Ideal therapeutic strategy has not been established by now and corticosteroid is probably an effective agent.

OBJECTIVE: To determine the expression of cyclooxygenase-2 (COX-2) mRNA in peripheral blood monocytes in patients with acute coronary syndrome (ACS), and to explore the effect of the expression of COX-2 mRNA in ACS. METHODS: The expressions of COX-2 mRNA in peripheral blood monocytes from 18 normal subjects and 42 ACS patients were analyzed by reverse transcription polymerase chain reaction (RT-PCR), and the monocytes from patients were incubated with celecoxib in vitro. The concentrations of interleukin-6 (IL-6) and matrix metalloproteinase-9 (MMP-9) in supernates of monocytes were measured by enzyme-linked immunosorbent assays (ELISA). RESULTS: The expression of COX-2 mRNA and the secrections of IL-6 and MMP-9 in peripheral blood monocytes in ACS patients significantly increased compared with those from normal controls [0.61 +/- 0.17 vs 0.11 +/- 0.09; (97.24 +/- 11.21) ng/L vs (22.15 +/- 6.30) ng/L; (41.20 +/- 8.41) g/L vs (11.76 +/- 4.23) g/L; all P < 0.05, respectively]. Celecoxib reduced IL-6 and MMP-9 secretion level of monocytes from ACS patients up to 48% and 50% respectively (all P < 0.05), in a concentration-dependent manner. CONCLUSION COX-2 in peripheral blood monocytes may play an important role in the acute coronary syndrome.
