OBJECTIVETo observe the effect of Chinese medicine and pharmacy (CMP) on the mortality of senile HIV/AIDS patients as adjunctive therapy.
METHODSHIV/AIDS patients of a certain rural area of Hanna Province, who were recruited in national CMP HIV treatment trial program (NTCMTP) in 2004, were enrolled as the CMP treatment group. HIV/AIDS patients in the same village without recruiting in NTCMTP were enrolled as the non-CMP treatment group. Data related to subjects were collected from the database of NTCMTP and National HAART Reporting System. Multiple regression analysis under Cox proportional hazard model was applied to examine the risk factors for death of senile HIV/AIDS patients.
RESULTSA total of 436 HIV/AIDS were enrolled in this study, 204 in the CMP treatment group and 232 in the non-CMP treatment group. There were 70 AIDS-relative deaths in the CMP treatment group, with 8-year mortality rate of 37.74%. There were 111 AIDS-relative deaths in the non-CMP treatment group, with 8-year mortality rate of 48.34%. The 8-year mortality rate was higher in the non-CMP treatment group than in the CMP treatment group (chi2 = 5.136, P < 0.05). Results of univariate Cox proportional hazards regression analysis showed the hazard ratio in the non-CMP treatment group was 1.41 times that of the CMP treatment group (P < 0.05). Result of multivariate Cox proportional hazards regression analysis showed the hazard ratio in the non-CMP treatment group was 1.44 times that of the CMP treatment group (P < 0.05). Besides, gender and marital conditions were significantly associated with death of HIV/AIDS patients.
CONCLUSIONCMP treatment was favorable to lower the mortality rate of senile HIV/AIDS patients, and its objective evaluation awaits for further prospective study.

Laggera pterodonta is commonly used for treating influenza in Southwest China, especially in Yunnnan province. The main clinical effects of L. pterodonta include anti-influenza, anti-microbial, anti-inflammatory. To investigate the anti-influenza A (H1N1) virus effect of L. pterodonta, neutralization inhibition and proliferation inhibition tests were performed. MDCK culture method was used to observe the cytopathic effect (CPE) of extracts from L. pterodonta in inhibiting influenza A (H1N1) virus and haemagglutination titre of H1N1 virus in vitro. The culture medium were collected at 24 h, 48 h, 72 h, 96 h, and detected by Real time RT-PCR, in order to compare the effect of different extracts from L. pterodonta on in vitro proliferation of H1N1, virus. The result of neutralization inhibition test showed that hemagglutination titer of ethyl acetate extract were 8 times lower at 72 h; in proliferation inhibition test, hemagglutination titer of ethyl acetate extracts reduced by 2 and 4 times. According to the results of Real time RT-PCR test, the H1N1 inhibition ratio of ethyl acetate extract was 72.5%, while the proliferation inhibition ratio of ethyl acetate extract was 25.3%; as for petroleum ether extracts, the H1N1 inhibition ratio was 60.2%, while the proliferation inhibition ratio was 81.4%. In conclusion, both ethyl acetate extract and petroleum ether extract of L. pterodonta have significant neutralization and direct proliferation inhibition effects on influenza A virus.

OBJECTIVETo study the changes in serum cortisol levels in adolescents with type 1 diabetes (T1DM) and elevated depressive symptoms.
METHODSTwenty-eight adolescents with T1DM and 31 healthy peers were assessed for depressive symptoms using a depression self-rating scale developed by the Epidemiological Survey Center. Selected subjects were classified into four groups: T1DM with elevated depressive symptoms group (n=15), T1DM without elevated depressive symptoms group (n=13), elevated depressive symptoms without T1DM group (n=15), and normal control group (n=16). Fasting blood samples were collected in the morning, and the levels of serum cortisol were compared among the four groups. The correlations of serum levels of cortisol and glycosylated hemoglobin A1c (HbA1c) with the score of depression self-rating scale were evaluated by Pearson correlation analysis.
RESULTSThe fasting serum cortisol levels in the 28 T1DM patients were significantly higher than in the 31 healthy peers (P<0.01). The fasting cortisol levels in the T1DM with elevated depressive symptoms group were significantly higher compared with those in the elevated depressive symptoms without T1DM group and normal control group (P<0.01). In adolescents with T1DM, serum HbA1c level was positively correlated with the score of depression self-rating scale (r=0.481, P=0.010).
CONCLUSIONSThe fasting serum cortisol levels in adolescents with T1DM and elevated depressive symptoms are significantly increased, suggesting that the patients with comorbidity of T1DM and depression develop dysfunction of the corticotropin-releasing hormone-adrenocorticotropic hormone-cortisol axis. The elevated depressive symptoms may be associated with a poor control of glucose metabolism.

OBJECTIVETo study the characteristics of the normal subjects with postural sway test and discuss the value of postural sway test in the diagnosis of dizzy patients.
METHODSTotally 112 normal subjects, 72 patients with peripheral vertigo, and 30 patients with central vertigo were examined using a stabilometer (EAB-100, Anima Co., Japan). Items include patterns, length of locus, envelope area, deflection average center displacement, and romberg rate were recorded and compared.
RESULTSThe postural sway was classified into the following five patterns: centripetal, forward and backward, right and left, diffuse, and multicentric. Centripetal pattern was the most prominent figure pattern in the normal subjects, while diffuse pattern was the most prominent figure pattern in the patients with central vertigo. When the normal subjects closed their eyes, age was linearly correlated with the length of locus, envelope area, rectangel area, and unit area path length (P < 0.05). Sex was not correlated to all of these parameters. The length of locus and envelope area in the patient groups were significantly increased when compared with the normal subjects (P < 0.0167). Romberg rate was not significantly different between the patients and the normal subjects.
CONCLUSIONSThe pattern of postural sway is useful for the diagnosis of vertigo. Age is an important factor that affects the balance function. Sex seems has no influence. Visual input plays an important role in maintaining postural balance. Stabilometer is a useful tool for evaluating balance function, and postural sway test may be a valuable assistant examination.

OBJECTIVETo prospectively investigate the effectiveness of suction drainage for correction of maxillofacial deformities caused by cystic lesions of the mandible.
METHODSSuction drainage was performed in 21 cases with large cystic lesions of the mandible which had expanded facial contour. Clinical and radiological examinations of these patients were carried out regularly. The volume of the cavity was measured during treatment. The expansion indexes on axial CT image and area of the cyst on a panoramic radiograph were measured preoperatively and postoperatively. The curettage via intraoral incision was completed until the extent of disease significantly shrunk.
RESULTSAfter a mean duration of suction drainage of 5.1 months, the volume and the size on the panoramic radiographic of the cystic lesions were reduced by an average of 84% and 63% respectively. The expansion indexes were reduced notably during treatment. Computerized tomography of the mandible showed that the contour of expanded mandible was restored greatly and notable new bone was formed in the area of cortex perforation.
CONCLUSIONSSuction drainage is a useful treatment modality for the primary management of giant cystic lesion of the mandible, and can fast correct maxillofacial deformities caused by bony expansion and perforation in the area of cystic lesions.

The changes of microRNA expression in rat hippocampus after traumatic brain injury (TBI) were explored. Adult SD rats received a single controlled cortical impact injury, and the ipsilateral hippocampus was harvested for the subsequent microarray assay at three time points after TBI: 1st day, 3rd day and 5th day, respectively. We characterized the microRNA expression profile in rat hippocampus using the microRNA microarray analysis, and further verified microarray results of miR-142-3p and miR-221 using quantitative real-time PCR. Totally 205 microRNAs were identified and up-/down-regulated more than 1.5 times. There were significant changes in 17 microRNAs at all three time points post-TBI. The quantitative real-time PCR results of miR-142-3p and miR-221 indicated good consistency with the results of the microarray method. MicroRNAs altered at different time points post-TBI. MiR-142-3p and miR-221 may be used as potentially biological markers for TBI assessment in forensic practice.

Chloride channels have been identified in vascular smooth muscle cells (SMCs). It has been shown that these channels are involved in myogenic tone regulation and neuromuscular transmission in various vascular beds. However, whether the chloride channels are responsible for the formation of excitatory junction potentials (EJPs) of SMCs in the spiral modiolar artery (SMA) remains unelucidated. In the present study, the effects of chloride channel blockers (niflumic acid, NFA; indanyloxyacetic acid 94, IAA-94; disodium 4, 4'-diisothiocyanatostilbene-2, 2'-disulfonate, DIDS) on EJP were explored in guinea pigs, using intracellular recording techniques on acutely isolated SMA. It was found that EJP was evoked in the majority of the SMCs (75%, n=49) with an adequate electronic stimulation. The amplitude of the EJP was partially blocked (30% approximately 80%) by combined application of alpha(1) receptor antagonist (prazosin) and alpha(2) receptor antagonist (idazoxan) at concentration of up to 1 micromol/L, and P(2x) receptor antagonist (PPADS, 10 approximately 100 micromol/L). NFA (100 micromol/L) could further inhibit the residual EJP in the presence of alpha(1), alpha(2)-adrenergic and P(2x) receptor antagonists. IAA-94 or DIDS not only inhibited the amplitude but also shortened the duration of EJP. Decrease of extracellular chloride concentration from 135.6 mmol/L to 60 mmol/L would enhance EJP. Moreover, IAA-94 (100 micromol/L) and DIDS (200 mumol/L) could reverse the enhancement of EJP by low extracellular Cl(-). NFA (100 micromol/L) could also block the residual depolarizations evoked by norepinephrine (NE, 1 approximately 50 micromol/L). Based on these results, it is inferred that NE could activate a novel adrenoceptor to open the chloride channel on the membrane of the SMCs, leading to a transmembrane Cl(-) current. This current is involved, at least partially, in the formation of EJP.

OBJECTIVETo explore correlation of seven apoptosis-related proteins (Hsp90a, p53, MDM2, Bcl-2, Bax, Cytochrome C, and Cleaved caspase3) with clinical outcomes of ALK+ anaplastic large-cell lymphoma (ALCL).
METHODSUsing immunohistochemistry and immunofluorescence double staining methods, the expressions of these seven apoptosis-associated proteins were studied to clarify their relationship with clinical outcomes of 36 ALK+ and 25 ALK-systemic ALCL patients enrolled between 1996 and 2006. The relationship of these apoptosis-regulating proteins with NPM-ALK status was also evaluated with the tyrosine inhibitor herbimycin A (HA) in vitro by immunocytochemistry, Western blotting and flow cytometric assays.
RESULTSThe presence of Hsp90α-, MDM2-, Bax-, Cytochrome C, and Cleaved caspase3-positive tumor cells was found significantly different in ALK+ and ALK-ALCLs, which was correlated with highly favorable clinical outcome. The Bcl-2- and p53-positive tumor cells were found in groups of patients with unfavorable prognosis. Inhibition of NPM-ALK by HA could reactivate the p53 protein and subsequent apoptosis-related proteins and therefore induced apoptosis in ALK+ ALCL cells.
CONCLUSIONOur results suggest that these seven proteins might be involved in apoptosis regulation and associated with clinical outcome of ALK+ systemic ALCLs. We also reveal a dynamic chain relation that NPM-ALK regulates p53 expression and subsequent apoptosis cascade in ALK+ ALCLs.

OBJECTIVETo observe the change of erythrocyte theology in rabbits with acute renal failure (ARF).
METHODSThirty-eight healthy rabbits were randomly divided into control group (n = 8), model group (establishing ARF model via intramuscular injection 1% HgCl2, and divided into 12 h, 24 h, 48 h subgroups, all n = 10), the arterial blood sample was taken out through carotid artery at corresponding times after anesthetization with urethane, for detecting the indices of renal function and erythrocyte rheology.
RESULTSThe levels of urea and creatinine in plasma of model rabbits at 12 h, 24 h and 48 h were higher than those of control group, and there was a rise trend along with the time extension. The erythrocytes electrophoresis time at 12 h of model group was higher, the electrophoresis rate and migration rate of erythrocytes were lower compared with those of control group; the erythrocytes electrophoresis time at 24 h of model group was lower and the electrophoresis rate and migration rate were higher compared with those of model group at 12 h; and there were no statistical differences in erythrocytes electrophoresis indices between model group at 48 h and other groups. Meanwhile, there was a rise trend in erythrocyte sedimentation rate (ESR), K value of equation and emendation along with the time extension of ARF, but these indices only at 48 h of model group was lower significantly than that of control group. There were no statistical differences in aggregation index and deformability index of erythrocytes among groups.
CONCLUSIONDuring the process of ARF, the erythrocytes electrophoresis time lengthen and electrophoresis rate and migration rate decrease at early stage, and these indices gradually return to normal; the indices of ESR increase gradually.
