Objective To make a concrete analysis of micro-perfusion pump and compatible syringes used in neonatal intensive care unit (NICU) for low birth weight infants,and to find solutions to the defects in application.Methods 20 ml sterile syringes were set different infusion rates (1ml/h,5ml/h,6ml/h,10ml/h),different infusion time (5min,30min,lh).Then,the card slot on the micro-perfusion pump where the end of 20ml sterile syringe was placed was regulated.The regulated syringes were also set different infusion rates (5ml/h,6ml/h,l0ml/h) and time as before.The error accuracy was calculated.Results The results showed that at the end stage of 20ml sterile syringes pumping,there was always 0.5～1.5 ml residual liquid which could not be pumped out,but perfusion pump displayed injection was completed.Before regulation,the error accuracy between different infusion rates of 20ml sterile syringes was 6.00％,3.80％,2.33％,1.30％ respectively.However,after improvement,the regulated syringes could completely pump all liquid out,and the error accuracy between different infusion rates and different infusion time was also superior to pre-improvement.Conclusions Improved micro-infusion pump and sterile solution prefilled syringe have no drug residual,and display high accuracy and small error accuracy.

Objective To compare the effect,relapse rate and outcomes between mycophenolate mofetil(MMF)and pulse intravenous cyclophosphamide(CTX)in the induction therapy of pauci-immune crescentic glomerulonephritis(PICGN)in Chinese.Methods A total of 44 patients who had PICGN[16 male,28 female,age(46.8?13.7)y],of whom 25 patients were ANCA positive,were enrolled in this study.All patients had renal involvement with ≥50% crescent formation prior to the study and received either MMF treatment(MMF group,n=22)or intermittent CTX pulse therapy(CTX group,n=22).The patients in both groups also received methylprednisolone(MP)pulse therapy followed by oral prednisone.General conditions,clinicopathological findings,remission rate,relapse rate,and outcomes were compared.All the patients were followed up until June 2005,with an average follow-up of 8～60(Med 27)months in the MMF group,and 6～72(Med 29)months in the CTX group.Results No significant difference was found between MMF group and CTX group in general conditions,base parameters of clinical and pathological findings.The remission rate at the 12th month in MMF and CTX group was 90.9% and 72.7% respectively.The complete remission rate in MMF group(59.1%)was significantly higher than that of the CTX group(27.3%)(P

Objective To investigate the clinical-pathological features, treatment and prognosis of thrombotic thrombocytopenic purpura in patients with lupus nephritis (LN). Methods A retrospective ana-lysis was carried out based on the clinical-pathological data for the treatment and prognosis of eight patients with LN related TIP. All patients had thrombocytopenia and hemolytic anemia, neurological symptoms and renal dysfunction. Six patients had fever. Results All 8 patients had sudden-onset of rapid progressive glomeurlonephritis (RPGN), one patient with continuous gross hematuria, the pathological features of these patients revealed TMA lesions. Immune suppressive therapy was initiated and blood purification therapy were applied in seven patients. Three cases had plasmapheresis and (or) immunoabsorption. One case was lost during follow-up, the other seven patients were followed with period at one year. One patient died, three patients went into peritoneal dialysis in which one of them was changed to hemodialysis finally. The other three patients had stable renal function. Conclusion The LN patients with TTP had severe clinical-patho-logical changes, rapid progressive and poor outcome, so we should diagnose and treat these patients as early as possible.

Objective To investigate the protective effect of dexamethasone on hearing loss induced by canalwall-down mastoidectomy.Methods A total of 76 patients (76 ears) were randomized to dexamethasone group and non dexamethasone group with 38 patients in each group.For dexamethasone group,gelfoam soaked with dexamethasone (5 mg/ml) was topically applied to the round window niche at the end of the surgery,and dexamethasone was administrated intravenously at the dosage of 5 mg/50 kg immediately after the surgery.While for non-dexamethasone group,dexamctbasone was not used.The pure-tone audiograms were performed before mastoidectomy and 90 days after the surgery.Absolute bearing change was defined as the difference in hearing thresholds in decibels before and after the surgery.Results The changes of bone conduction thresholds in dexamethasone group were 8.3± 3.9 dB at 6 kHz,11.3±5.2 dB at 8 kHz,and 10.1±7.2 dB for HPTA (4-6-8 kHz high tone average).As in non-dexamethasone group,the changes of bone conduction thresholds were 13.7±4.6 dB at 6 kHz,25.1±5.4 dB at 8 kHz,19.3±9.7 dB for HPTA.There were significant differences in the changes of bone conduction thresholds between dexamethasone and non dexamethasone groups at frequencies of 6 kHz (P=0.039),8 kHz (P=0.007) and HPTA (P=0.009).Conclusion The results demonstrated that application of dexamethasone significantly reduced sensorineural high frequencies (6 kHz and 8 kHz) hearing loss after canal-wall down mastoidectomy,thus the use of dexamethasone is recommended.

Objective To study the protective effects of salvia miltiorrhiza on acute acoustic trauma (AAT) showed by temporary threshold shifts (TTS) induced by impulse noise.Methods A total of 62 male soldiers from a boot camp were randomly divided into the experimental group and the control group,each with 31 persons.The experimental group was treated with salvia miltiorrhiza,and the control group with placebo.Salvia miltiorrhiza was taken orally at the dosage of 780 mg each time,three times a day for 3 consecutive days before the live fire training and 1 day after the live fire training.The pure tone thresholds of right ears of these two groups were measured and compared 72 hours before live fire training and 6 hours after the live fire training.Results The puretone averages at 0.5,1 and 2 kHz of the right ears of the experimental group and the control group before live fire training were 16.32±6.12 dB and 16.21±5.42 dB,respectively,and the averages at 4,6 and 8 kHz were 14.22±5.16 dB and 14.89±5.38 dB,respectively.There were no significant differences between the 2 groups(P＞0.05).The PTAs of the right ears of the experimental group and the control group 6 hours after live fire training were 21.88±5.71 dB and 21.66±6.62 dB,respectively(P＞0.05),while the HPTAs were 25.89 ± 7.97 dB and 39.75 ± 7.84 dB,respectively(P＜0.01).There were significant differences in TTS between the two groups at 4,6 and 8 kHz(P＜ 0.01).Conclusion Salvia miltiorrhiza can reduce TTS at high frequencies induced by AAT.It has a potential preventive effect on AAT.

OBJECTIVETo investigate retrospectively the incidence, distribution of primary disease and clinicopathologic characteristics of diffuse crescentic glomerulonephritis (DCGN) in Chinese patients.

METHODSOne hundred and seventy-two consecutive patients diagnosed as having DCGN out of 9828 cases of non-transplanting renal biopsies over sixteen years, were studied. DCGN is categorized into three types according to immunopathologic characteristics. The incidence of this disease, its primary diseases, clinical characteristics and serum antineutrophil cytoplasmic antibodies (ANCAs) were analyzed.

RESULTSThe distribution of patients among the three classifications was 8.7% type I, 68.6% type II and 22.7% type III. Clinically, the majority of patients (69.8%) presented rapidly progressive glomerulonephritis (RPGN), but 30.2% manifested a chronic nephritic syndrome or chronic renal failure. In terms of related conditions, 93% were anemic, 61.6% had hypertension, 50.6% oliguria, 45.3% nephrotic syndrome, 43% uremic syndrome and 39.5% displayed gross hematuria. Those patients who were positive in serum for ANCAs had predominantly type III DCGN. Two cases with anti-GBM-antibody crescentic glomerulonephritis and three with lupus nephritis were also positive for ANCAs in serum.

CONCLUSIONDCGN is not rare in Chinese patients. A majority of patients in our study presented with RPGN, but 30.2% manifested a chronic renal failure. Lupus patients with DCGN that were positive for ANCAs had more severe vasculitic lesions.

OBJECTIVETo analysis the pathological demography in Chinese patients undergoing renal biopsy from our nephrology center.

METHODSBetween January 1979 and October 2000 in Jinling Hospital, Nanjing, China, 10,002 attempts of percutaneous renal were performed in patients with renal disease from 33 provinces of China. The pathological classifications were made according to the WHO criteria of 1982 for renal pathology or the modified WHO criteria of 1995 by a panel of pathologists and nephrologists during routine clinical-pathological rounds. The pathological demography between those specimens collected from 1979 - 1989 and those from 1990 - 1999 was compared.

RESULTSThe mean age of the 10,002 subjects undergoing renal biopsy was 31.4 +/- 13.0 years (ranging from 1 to 78 years), with a male to female ratio of 1.3:1; for the 592 renal transplant recipients, the mean age was 37.5 +/- 9.1 years (ranging from 16 to 66 years), with a male to female ratio of 2.36:1. Primary glomerular diseases (PGD) accounted for 71% of the total patients undergoing renal biopsies, secondary glomerular nephritis (SGN) 23%, tubular-interstitial diseases 3.2%, unclassified renal diseases 1.3%, hereditary and congenital renal diseases 1.0%, end stage renal diseases 0.96%, and recently realized or rare renal diseases 0.15%. IgA nephropathy (IgAN) was the most frequent pathological pattern (40%) of PGD, followed by mesangial proliferative lesion (MsPL) (30%), membranous nephropathy (MN) (10%), and focal segmental glomerulosclerosis (FSGS) (6%). Lupus nephritis (LN) was the most pathology common seen (74%) in SGN. During the 22 years of the study period, there was a steady increase in patients with SGN discovered during pathological evaluation of renal disorders. A rise in prevalence was found in IgA nephropathy, MN (both P < 0.001), crescentic glomerulonephritis (P < 0.0001), anti-GBM disease, and hemolytic-uremic syndrome/thrombotic thrombocytopenic purpura related renal damages (both P < 0.001). There was a decrease in endocapillary proliferative glomerulonephritis (P < 0.001) and IgM nephropathy (IgMN) (P < 0.01) from 1990 - 1999 as compared to 1979 - 1989. Infrequent renal pathological entities were also diagnosed in this group, including Niemann Pick disease, Fabry's disease, POEMS syndrome, and lipoprotein glomerulonephropathy.

CONCLUSIONSThis is the largest series of renal biopsy data in China, and therefore may reflect the demographic picture of renal diseases in this country. Changes in prevalence of renal pathological entities were reflected in this group of patients over the last 22 years. In primary glomerular diseases, IgA nephropathy is still the most frequently observed pathological pattern. In SGN, LN appeared the most often. Increased prevalence was found in anti-GBM nephritis and HUS/TTP.

Objective : To study the effect of crisaborole on imiquimod (IMQ) Ⅳinduced psoriasis in mice. Methods: Forty eight Balb/c mice were randomly divided into crisaborole group (7. 5 , 15 , 30 mg/cm2），halometasone group ( 15 mg/cm2 ) , model group and normal group. IMQ was applied to the back of mice to establish the psoriasis model. Psoriasis area and severity index ( PASI) score was calculated , pathological changes , skin epidermal thickness and inflammatory cell infiltration in the dermis were observed by HE staining. The expressions of keratin (K) 1 , K10 , K6 , K16 and K17 in skin lesions were detected by Western blot and immunohistochemistry. The levels of cyclic adenosine monophosphate ( cAMP) , protein kinase A ( PKA) and phospho⁃cAMP response element binding protein (p⁃CREB) were detected. Results : Compared with the model group , the PASI score of the crisaborole group decreased , the expression levels of proliferative keratin ( K6 , K16 and K17 ) decreased( F = 12. 62、19. 41、28. 39 ,P < 0. 01) , and the expression levels of differentiation keratin (K1 and K10) increased(F = 27. 95、9. 64 , P < 0. 01) . Conclusion Crisaborole plays a therapeutic role in IMQ⁃induced psoriasis in mice by regulating the abnormal proliferation and differentiation of keratinocytes.
