Objective To evaluate the effect of pulmonary function test on infants with obstructive sleep apnea-hypopnea syndrome (OSAHS). Methods Forty-eight patients were divided into two groups based on physical examination. Pulmonary function were measured in 48 patients. Age-matched healthy infants were enrolled as controls. The parameters included ratio of volume to PEF to total expiratory volume(VPTEF/VE,tPTEF/tE),inspiratory time/expiratory time(TI/tE),inspiratory time/total respiratory time(TI/Ttot),ratio of 50% of the tital inspiratory flow to tital volume(TIF_ 50 /V_T),mean inspiratory flow(V_T/TI),function capacity(FRCp),resistance effective(Reff).Results TI/Ttot,ratio of 50% of the tital expiratory flow to 50% of the tital inspiratory flow(TEF_ 50 /TIF_ 50 ),FRCp,Reff were significantly higher in patients compared with controls(P

ObjectiveTo investigate the clinical manifestation, mechanism and optimal treatment of hydronephrosis after spinal cord injury. Methods58 slight and moderate cases were retrospectively analyzed. ResultsThere were no differences in the remitted time among the therapies of indwelling catheter, intermittent catheterization and medicine, mixed therapy. 56 (96.55%) SCI hydronephrosis remitted after treatment, 28(48.28%) recurred within 3 months. The recurrence rate of the patients with detrusor sphincter dyssynergia (57.14%) was higher than that of the detrusor hyperreflexia (28.57%) and the detrusor hyporeflexia (14.29%). The recurrence was associated with the fact that many patients couldn't keep up with the systematic therapy.ConclusionThe onset of SCI hydronephrosis is indistinct and recurrent easily. Keeping up with intermittent catheterization and taking medicine can prevent SCI hydronephrosis recurrence effectively.

OBJECTIVETo assess clinical therapeutic effect and safety of acupuncture combined with fuxiting on depression.

METHODSFifty-three cases of depression were divided into an observation group (n = 30) treated by acupuncture combined with fuxiting and a control group treated by fuxiting. Their clinical therapeutic effects were assessed by HAMD, HAMA and CGI, and adverse effects by TESS.

RESULTSAfter treatment of 6 weeks, the total effective rate was 80.0% in the observation group and 69.6% in the control group with no significant difference between the two groups (P > 0.05). There were significant differences in scores of HAMD and HAMA before and after treatment in the two groups (P < 0.01), with no significant difference between the two groups (P > 0.05). The adverse effect in the observation group was less and milder than that in the control group.

CONCLUSIONAcupuncture combined fuxiting has good therapeutic effect on depression with less and mild adverse effects.

Purpose:To clarify the perioperative management for living-related kidney donors. Methods:Thepre, mid, and postoperative clinical manifestations of 5 living related donors were analyzed retrospectively. Re-sults:5 living-related kidney donors were dismissed 15 days after the operations on average. Following up for 3～10 months, their postoperative blood routine, urine routine, hepatic function, renal function, the amount oturine protein in 24 hours were all within normal range. Conclusions:The safety of operation for living-related kid-ney donors is high and the donors can recover well.

OBJECTIVETo observe the effect of bone morphogenetic protein-7 (BMP-7) on the transdifferentiation of cultured human tubular epithelial cell (HKC) induced by TGF-beta1 and to elucidate its possible mechanism.

METHODSThe cultured HKC cells were divided into 5 groups: serum-free group (negative control); single TGF-beta1 treated group (positive control); single BMP-7 treated group; combined TGF-beta1 and BMP-7 treated group; and BMP-7 pre-treated group. Expression of keratin of HKC cells was assessed by indirect enzyme immunohistochemistry (IEI), expression of alpha-smooth muscle actin (alpha-SMA) and E-cadherin by immunohistological method, percentage of alpha-SMA positive HKC cells by flow cytometry, and mRNA expression of alpha-SMA, TGF-beta1, and TGF-beta type II receptor by reverse transcription PCR.

RESULTSThe expression of alpha-SMA and the percentage of alpha-SMA positive HKC cells markedly increased after having been treated by TGF-beta1 while the expression of E-cadherin and keratin decreased. In the group pre-treated with BMP-7 (50 ng/ml) and then added with TGF-beta1 (8 ng/ml), expression of alpha-SMA was significantly lower than in the positive control group, while expression of E-cadherin and keratin significantly higher than in the positive control group. Measurement of the percentage of alpha-SMA positive HKC found significant deference between the combined TGF-beta1 and BMP-7 treated group and the positive control group (9.7% vs 19.8%; 5.8% vs 19.8%; P < 0.05). Significant difference existed between the BMP-7 (50 ng/ml) pre-treated group and the positive control group (8.7% vs 19.8%, P < 0.05). mRNA expression of alpha-SMA was measured by RT-PCR and the results showed that it significantly decreased in the group treated or pre-treated with BMP-7 (50 ng/ml) (15% and 12% of the results in the positive control group, respectively). The mRNA expression levels of both TGF-beta1 and its type II receptor significantly decreased (28% and 19%; 47% and 36%, compared with the positive control group, respectively).

CONCLUSIONTransdifferentiation of cultured renal epithelial cell induced by TGF-beta1 can be inhibittd by certain levels of BMP-7, cultured together with TGF-beta1 or pretreated. BMP-7 can prevent and inhibit the mRNA expression of TGF-beta1 and its type II receptor, which may be an important mechanism by which BMP-7 inhibit the transdifferentiation of renal tubular epithelial cell.

OBJECTIVETo research the hereditary stability of Dendrobium huoshanense which were subcultured 7-8 times in the same tissue culture system.

METHODUsing three primers of arbitrary decamer oligonucleotide sequences from 20 primers for DNA amplification, random amplified polymorphic DNA (RAPD) were performed.

RESULTThe genetic similarity coefficient was varied from 85.4% to 98.4%. The variation of protocorm, germination and monoleaf were rather more notable than that of bileaf and inflorescence.

CONCLUSIONThe variation of the same pod is quite small. It is feasible to set up the rapid propagation system of D. huoshanense

OBJECTIVEIn order to explore the role of toll-like receptors 2 (TLR2) in initiating inflammatory response, the expression of TLR2 of the liver and IL-18, TNF-alpha and IFN-gamma of plasma in fulminant hepatic failure was analysed.

METHODSD-galactosamine (D-Gal, 900 mg/kg) and lipopolysaccharide (LPS, 10 microg/kg) were administered intraperitoneally into the BALB/C mice. To evaluate the hepatic injury, serum transaminase (ALT and AST) and plasma IL-18, TNF-alpha and IFN-gamma were determined and the mortality was observed at various time points following the intraperitoneal injection. The level of TLR2 mRNA was measured by semiquantitative RT-PCR. The protein expression of TLR2 in the liver was detected by immunohistochemistry. The data was analyzed by SAS software.

RESULTSAfter 4 hours of intraperitoneal injection of D-Gal/LPS, the serum transaminase and plasma IL-18, TNF-alpha and IFN-gamma levels were elevated. The treated mice began to die at 7 hours. The mortality reached up to 80% at 10 h. TLR2 mRNA was expressed at a low level in liver tissues of normal mice, while it was significantly increased and maintained at a higher level following intraperitoneal injection with D-Gal/LPS. The expression of TLR2 protein was similar to that of the TLR2 mRNA, and the expression of TLR2 mRNA was positively correlated with the concentration of plasma IL-18, TNF-alpha and IFN-gamma (r=0.36, P=0.02; r = 0.48, P 0.003; r = 0.72, P<0.001) at different time points.

CONCLUSIONSOur results showed that TLR2 was involved in initiating and inducing the expression of proinflammation cytokines in this model of fulminant hepatic failure. The results suggest that adjusting the expression of TLR2 might be a new strategy in preventing the development of infectious diseases
