OBJECTIVETo observe interventional effects of anti-viral therapy and Compound Qin-gre Granule (CQG) on host cellular immune functions of acute virus infection patients.

METHODSThirty acute virus infection patients were recruited to detect peripheral lymphocyte subsets. They were randomly assigned to two groups, the Western medicine treatment group (treated with anti-virus Western medicine) and the integrative medicine treatment group (treated with anti-virus Western medicine plus CQG). T-cell subsets were re-examined 7 days later. Changes between before and after treatment were observed. Effect on host cellular immune functions and efficacy were compared between the Western medicine treatment and the integrative medicine treatment.

RESULTSCompared with the normal control group, the percentage of peripheral T cells increased, and the percentage of B/NK cells decreased in acute virus infection patients (P < 0.01). Meanwhile, in T cell subsets, the percentage of CD8+ T cells and CD8+ CD38+ T cells increased (P < 0.05, P < 0.01); and percentages of CD4+ T cells, CD4+ CD28 + T cells, and CD8+ CD28+ T cells decreased (P < 0.05, P < 0.01). After one-week treatment, percentages of CD4+ T cells, CD4+ CD28+ T cells, and CD8+ CD28+ T cells increased (P < 0.05, P < 0.01), while the percentage of CD8+ CD38+ T cells decreased (P < 0.01). More significantly, these changes were greater in the integrative medicine treatment group than in the Western medicine treatment group (P < 0.05).

CONCLUSIONSDisarranged cellular immune functions existed in acute virus infection patients. CQG could significantly improve viral infection induced immunologic derangement and immunologic injury.

OBJECTIVETo observe the effect of Baichanting Compound (BC) on dopamine (DA) in striatum of Parkinson's disease (PD) mice, and to screen the optimal component proportion.

METHODSThe PD model was established in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) induced C57BL/6 mice. By using uniform design, they were intervened by three extracts of BC in different proportions [Acanthopanax senticosus extract (X1): white peony root extract (X2): Uncaria rhynchophylla extract (X3) = 30.00: 34.92: 82.50, 48.00: 19.98: 72.19, 18.00: 44.88: 61.88, 36.00: 29.94: 51.56, 54.00: 15.00: 41.25, 24.00: 39.90: 30.94, 42.00: 24.96: 20.63). Equal volume of 5% carboxymethylcellulose sodium was administered to mice in the model group and the normal group by gastrogavage. All medication was lasted for 20 successive days. The dopamine (DA) content was determined by ultra performance liquid chromatography tandem mass spectrometry (UPLC-MS). Except 10 in the normal group, 20 PD model mice were screened and divided into the model group and the BC group (with the optimal proportion) according to random digit table. BC extract in optimal proportion was administered to mice in the BC group by gastrogavage, while equal volume of 5% carboxymethylcellulose sodium was administered to mice in the model group and the normal group by gastrogavage. All medication was lasted for 20 successive days. Praxiology was observed in each group. DA content in striatum was also detected. Results Compared with the normal group, the DA content in striatum decreased significantly in the model group (P < 0.01), suggesting a successful PD modeling. Compared with the model group, the DA content in striatum increased significantly in 1 and 2 groups (P<0.05). According to results of quadratic polynomial stepwise regression statistics, the regression equation obtained was: Y = 0.265 + 0.026 X 2 - 0.056 X 3 + 0.334 x 10(-3) x X1 x X3 + 0.691 x 10(-3) X X3(2). X3 extract was the main factor influencing the effectiveness (P < 0.01). The optimal proportion of BC was predicted by the regression equation: X1 = 54.00 mg/(kg x d), X2 = 44.88 mg/(kg x d), the X3 = 82.50 mg/(kg x d). The pole climbing time was shortened, times of autonomic activities increased, DA content was elevated, all with statistical difference in BC groups (P < 0.01, P < 0.05).

CONCLUSIONBC could increase DA content in PD model mice with the optimal proportion as 54.00: 44.88: 82.50.

Objective To explore protective effect of topiramate (TPM) and folic acid (FA) on mitochondrial damage in hippocampal CA3 neurons during pentylenetetrazol- induced kindling in immature rats.Methods Pentylenetetrazol (PTZ) - induced kindling in rats was used to establish rat models of epilepsy.Forty-eight 3-week-old male Wistar rats were randomly divided into 4 groups: two therapy groups with TPM 40 mg/(kg?d) or TPM 40 mg/(kg?d) and FA 5 mg/(kg?d) administration, 2 control groups (positive control group and negative control group) with the equal amount of distilled water administration. The seizure behaviors of rats were evaluated. Two months later, the rats were killed and the brain sections were made. The mitochondrial ultrastructures of neurons in hippocampal CA3 region were observed with transmission electron microscope.Results In the positive control group, the frequency of seizure was (48.4 ? 3.7)times, while in TPM group (44.3 ? 3.1)times and in TPM and FA group(40.8 ? 3 .7)times.The differences were significant among three groups (Pa

A P2P technology-based personal digital library sharing model, MIPDLM, was established using the P2 P technology according to the decentralized characteristics of personal digital library in order to improve the per-sonal digital library sharing, in which the topology remodeling was studied according to the interest clusters in per-sonal digital library. The searched messages are constantly transmitted to personal digital library with a high interest similarity, which can thus reduce the searching scope. Simulation experiment showed that MIPDLM could improve the successful searching rate, reduce the average path length, and increase the location rate of resources.

Objective:To compare the effectiveness of fire needle versus Western medicine in the treatment of herpes zoster. Methods:Randomized controlled trials comparing fire needle with Western medicine in the treatment of herpes zoster were identified using 8 databases. A meta-analysis was performed using RevMan 5.3 software. Results:Eight trials involving 569 patients were included in this meta-analysis, and the results showed that fire needle was superior to Western medicine comparing the effective rate [risk ratio (RR)=1.13, 95％ confidence interval (CI): 1.06 to 1.20;P=0.0002], the visual analog scale (VAS) score [mean difference(MD)=–7.95, 95％ CI: –10.71 to –5.20;P<0.00001], time of pain disappearance (MD=–7.61, 95％CI: –9.38 to –5.84;P<0.00001), time of blister-stop (MD=–1.34, 95％CI: –1.51 to –1.18;P<0.00001), time of crusted scab (MD=–2.92, 95％CI: –3.62 to –2.23;P<0.00001), and time of scab off (MD=–4.64, 95％CI: –5.83 to –3.46;P<0.00001). In addition, a significantly lower incidence of postherpetic neuralgia was found in the fire needle group in 30 d (RR=0.23, 95％CI: 0.11 to 0.51;P=0.0002) and 60 d (RR=0.33, 95％CI: 0.12 to 0.91; P=0.03) after treatment. Conclusion:Fire needle has a favorable effect in increasing the effective rate, relieving pain, recovering skin lesions and decreasing incidence of postherpetic neuralgia in the treatment of herpes zoster. However, considering the limitations in this study, the findings should be interpreted cautiously.

OBJECTIVESTo study the relationship between the mutation of Leu60Val in HBV core region and the cellular immunity in patients with chronic hepatitis B (CHB).

METHODSHBV DNA C gene mutation was confirmed by polymerase chain reaction (PCR) and sequencing the products directly. The cytokines (IFN-gamma, TNF-alpha and IL-2) levels in serum were measured by enzyme linked immunosorbent assay (ELISA). The distribution of T-lymphocyte subpopulations in peripheral blood was detected by flow cytometry (FCM).

RESULTSThe mutation of Leu60Val was found in 19 out of the 91 CHB patients. With the CHB severity, the mutation rate was getting higher, especially in the severe hepatitis group. The IFN-gamma and TNF-alpha levels were much higher in mutant strain group than those in wild strain group (t=2.584, 4.766, P<0.01), so was the ratio of CD4+/CD8+ (t=2.275, P<0.05).

CONCLUSIONThe mutant strain of 60Val may increase affinity to HLA-I molecule, or up-regulate the expression of HLA-I molecule, resulting in the activation of CTL to release the cytokines and cause immune response in liver.
