Objective: To observe the clinical efficacy of heat-sensitive moxibustion for adjuvant treatment of depression in Parkinson disease and explore its mechanism. Methods: A total of 80 patients with Parkinson disease coupled with depression were randomized into an observation group and a control group, with 40 cases in each group. The control group was treated with levodopa and benserazide hydrochloride tablets and paroxetine tablets, while the observation group was treated with heat-sensitive moxibustion on the basis of the medications in the control group. The treatment course was 2 months. The Hamilton depression scale-17 (HAMD-17), unified Parkinson's disease rating scale (UPDRS) and Parkinson's disease quality of life questionnaire-39 (PDQ-39) were scored before and after the treatment, and the efficacy was evaluated after treatment. Levels of patients' serum dopamine (DA), 5-hydroxytryptamine (5-HT), tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) were detected before and after the treatment. Results: After treatment, the total effective rate of the observation group was higher than that of the control group (P<0.05). The HAMD-17 scores in the two groups decreased significantly after treatment (both P<0.05), and the score in the observation group was obviously lower than that in the control group (P<0.05). The component scores and total scores of UPDRS in both groups decreased significantly (all P<0.05), and the scores in the observation group were lower than those in the control group (all P<0.05). The score of PDQ-39 in the observation group decreased significantly (P<0.05), and was lower than that in the control group (P<0.05). After treatment, the serum DA and 5-HT levels in the observation group increased significantly (both P<0.05) and the TNF-α and IL-6 levels decreased significantly (both P<0.05), which were statistically different from those in the control group (all P<0.05). Conclusion: Heat-sensitive moxibustion has certain auxiliary effect in treating depression in Parkinson disease, significantly improving clinical symptoms and the quality of life, which may be related to the up-regulation of DA and 5-HT levels and down-regulation of TNF-α and IL-6 levels.

Objective: To observe the clinical efficacy of acupoint pressure plus long-snake moxibustion for upper-limb spastic hemiplegia after cerebral infarction. Methods: A total of 100 patients were randomized into a control group and an observation group, with 50 cases in each group. Both groups were treated with the same conventional internal medicine and rehabilitation training. The control group was treated with additional acupoint pressure therapy, and the observation group was treated with long-snake moxibustion on the basis of the treatment given to the control group. The Ashworth grade, Fugl-Meyer assessment upper limb scale (FMA-UL) and Barthel index (BI) were evaluated, and the root mean square (RMS) values of biceps brachii and flexor carpi radialis on the affected side were measured before and after treatment. The efficacy was evaluated after treatment. Results: After treatment, the total effective rate of the observation group was significantly higher than that of the control group (P<0.05). After treatment, the Ashworth grade of the observation group was superior to that of the control group (P<0.05). The scores of FMA-UL and BI in both groups increased compared with those before treatment (all P<0.05), and the scores of FMA-UL and BI in the observation group were higher than those in the control group (both P<0.05). The RMS values of biceps brachii and flexor carpi radialis in both groups decreased compared with those before treatment (all P<0.05), and the RMS values of biceps brachii and flexor carpi radialis in the observation group were lower than those in the control group (both P<0.05). Conclusion: Based on conventional internal medicine and rehabilitation training, acupoint pressure plus long-snake moxibustion has great therapeutic efficacy for upper-limb spastic hemiplegia after cerebral infarction. It can improve the degree of spasticity of the affected upper limb, reduce the muscle tone of biceps brachii and flexor carpi radialis on the affected side, and enhance the mobility of the affected limb and the activities of daily living.

OBJECTIVETo study the impact of IFN-gamma on liver fibrosis and its possible mechanism. Thirty healthy male SD rats were randomly divided into two groups: fibrosis model group, IFN-gamma treatment group. Experimental liver fibrosis was induced by subcutaneous injection of CCl4. After 12-week-treatment, serum hyalurnic acid and TGF-beta1 was examined, histopathological changes and degrees of fibrosis were observed by optical microscopy. Meanwhile, the expression of TGF-beta1, TbetaR- I and Smad2/3 proteins was detected by immunohistochemistry and quantified by using computerized image analysis.

RESULTS(1) Pathological observation of hepatic specimens: histological examination showed that there were significant difference between normal group and fibrosis model group by comparing with the degrees of inflammation and fibrosis (P < 0.05). And the difference between fibrosis model group and IFN-gamma treatment group was significant (P < 0.05). (2) Changes of the hepatic fibrosis index (serum HA and TGF-beta1): the levels of serum HA, TGF-beta1 in fibrosis model group were higher than IFN-gamma treatment groups (P < 0.05). (3) Changes of gene protein levels about TGF-beta1/Smad: the expressions of TGF-beta1, TbetaR- I and Smad2/3 in rat hepatic tissue were detected with immunohistochemistry techniques. The expressions of the three items in model group were higher than normal group (P < 0.01). The difference between model group and IFN-gamma treatment group was significant (P < 0.05);

CONCLUSIONIFN-gamma treatment group had significant results on treating experimental hepatic fibrosis. By the way of inhibiting expressions of TGF-beta1, TbetaR- I, Smad2/3, IFN-gamma treatment group exerted its anti-fibrosis effect.

AIM:To investigate the effect of insulin on vascular smooth muscle cells (VSMCs) proliferation and to evaluate the intracellular signaling pathways involved.METHODS:VSMCs separated from Sprague-Dawley rats were used in this study. The proliferation of VSMCs induced by insulin was assayed by [3H]-thymidin incorporation. The protein expression and activity of p-ERK1/2 were determined by immunblot and [?-32P]ATP incorporation.RESULTS:Insulin induced cell proliferation in a concentration-dependent manner. The proliferative effect of insulin on VSMCs was inhibited partly by LY294002 (48.8%),an inhibitor of PI-3 kinase,and the ERK1/2 inhibitor PD98059 (43.6%),respectively. Moreover,phosphorylation of ERK1/2 and activity of ERK1/2 induced by insulin were also inhibited partly by LY294002.CONCLUSION:PI-3 kinase and ERK1/2 are involved in insulin induced VSMCs proliferation.

Objective To study the effect of antiapoptosis factors PED/PEA-15 and XIAP on prostate cancer cells(PC-3)apoptosis.Methods The expressions of XIAP and PED/PEA-15 in prostate cancer cells(PC-3)were respectively assayed using the RT-PCR technique.XIAP and PED/ PEA-15 specific siRNA vectors were designed and constructed and then were transiently cotransfected into PC-3 cells under induction of liposome.The effects of siRNA vectors on PED/PEA-15 and XIAP transcription were assayed by RT-PCR technique,and the effect of XIAP and PED/PEA-15 on cancer cell apoptosis were determined by flow cytometry and microscope observation.Results PED/PEA- 15 and XIAP were both highly expressed in PC-3 cells.Enzyme digestion analysis and DNA sequencing confirmed that the PED/PEA-15 and XIAP-specific siRNA expression vectors were constructed successfully.The designed siRNA sequences of PED/PEA-15 and XIAP could specifically inhibit their transcription.The PC-3 cells which were cotransfected with PED/PEA-15 and XIAP- specific siRNA vectors were more sensitive to doxorubicin.The apoptosis rate of cotransfected cells was significantly increased.Conclusions PED/PEA-15 and XIAP might be involved in the development of prostate cancer.

OBJECTIVETo explore the effects of rotatory reduction manipulation and acupoint massage on blood flow velocity of vertebrobasilar artery (VBA) in younger cervical vertigo of high velocity,and to observe the difference of clinical therapeutic effect between two manipulations.

METHODSSeventy-six patients who diagnosed as high flow velocity of younger cervical vertigo were randomly divided into rotatory reduction manipulation group (group A, 38 cases)and acupoint massage group (group B, 38 cases). The changes of flow velocity of VBA before and after treatment were observed using transcranial Doppler (TCD) and the therapeutic effects were observed also.

RESULTSThe mean flow velocity in left vertebral artery (LVA)and basilar artery (BA)of group B and in BA of group A were significantly decreased as compared with those before treatment (P < 0.05, P < 0.01) 1 week after treatment,and there was significant difference in the change of mean flow velocity in LVA between two groups (P < 0.01). The mean velocity in LVA, right vertebral artery (RVA) and BA were obviously lower than thosfre before treatment in two groups (P < 0.01) 3 weeks after treatment. There was obvious difference in LVA, RVA between two groups (P < 0.01). The therapeutic effect of group B was superior to that of group A (P < 0.05).

CONCLUSIONThe effect of acupoint massage on flow velocity of VBA was superior to that of rotatory reduction manipulation, and the therapeutic effect of acupoint massage might be better than that of rotatory reduction manipulation in treating younger cervical vertigo of high flow velocity.

The aim of this study was to observe and compare the endogenous circadian rhythm and photoresponse of Clock gene transcription in the suprachiasmatic nucleus (SCN) and pineal gland (PG) of rats. With free access to food and water in special darkrooms, Sprague-Dawley rats were housed under the light regime of constant darkness (DD) for 8 weeks (n=36) or 12 hour-light: 12 hour-dark cycle (LD) for 4 weeks (n=36), respectively. Then, their SCN and PG were dissected out every 4 h in a circadian day, 6 rats at each time (n=6). All animal treatments and sampling during the dark phases were conducted under red dim light (<0.1 lux). The total RNA was extracted from each sample and the semi-quantitative RT-PCR was used to determine the temporal mRNA changes of Clock gene in the SCN and PG at different circadian times (CT) or zeitgeber times (ZT). The grayness ratio of Clock/H3.3 bands was served as the relative estimation of Clock gene expression. The experimental data were analyzed by the Cosine method and the Clock Lab software to fit original results measured at 6 time points and to simulate a circadian rhythmic curve which was then examined for statistical difference by the amplitude F test. The main results are as follows: (1) The mRNA levels of Clock gene in the SCN under DD regime displayed the circadian oscillation (P<0.05). The endogenous rhythmic profiles of Clock gene transcription in the PG were similar to those in the SCN (P>0.05) throughout the day with the peak at the subjective night (CT15 in the SCN or CT18 in the PG) and the trough during the subjective day (CT3 in the SCN or CT6 in the PG). (2) Clock gene transcription in the SCN under LD cycle also showed the circadian oscillation (P<0.05), and the rhythmic profile was anti-phasic to that under DD condition (P<0.05). The amplitude and the mRNA level at the peak of Clock gene transcription in the SCN under LD were significantly increased compared with that under DD (P<0.05), while the value of corresponding rhythmic parameters in the PG under LD were remarkably decreased (P<0.05). (3) Under LD cycle, the circadian profiles of Clock gene transcription induced by light in the PG were quite different from those in the SCN (P<0.05). Their Clock transcription rhythms were anti-phasic, i.e., showing peaks at the light phase ZT10 in the SCN or at the dark time ZT17 in the PG and troughs during the dark time ZT22 in the SCN or during the light phase ZT5 in the PG. The findings of the present study indicate a synchronous endogenous nature of the Clock gene circadian transcriptions in the SCN and PG, and different roles of light regime in modulating the circadian transcriptions of Clock gene in these two central nuclei.

Objective To explore the activation and function of Janus protein-tyrosine kinase (JAK)/ signal transducer and activator of transcription (STAT1) signal transduction pathway in kidney,lung and brain of MRL/lpr mice.Methods MRL/lpr mice with systemic lupus erythematosus (SLE) were studied at the age of 12 weeks up.Non-SLE MRL/lpr mice were used as controls.We used phosphospecific antibodies to detect STAT1 activation in kidney,lung and brain by immunohistochemistry and Western blots.Gene expression of the STAT induced feedback inhibitors of cytokine signaling 1 (SOCS-1) was investigated by SYBR green I real-time reverse transcriptase polymerase chain reaction (PCR).Results Phosphorylation of STAT1 protein was markedly activated in these three organs,although renal and pulmonary STAT1 activation were much more evidently activated.SOCS-1 gene expression increased in all three organs,while renal SOCS-1 gene expres- sion increased less than lung and brain.Conclusion The activation of JAK/STATI signal transduction path- way may be pathogenic in the organ involvement and progression of SLE.The pathogenesis of lupus nephritis may also be associated with the down-regulation of SOCS-1 feedback inhibition.
