Recently many researches have demonstrated that insulin resistant (IR), as an important pathologic process, is increasingly involved with a series of diseases such as central obesity and diabetes. Hypertension is highly associated with IR. The relationships between IR and glucose or lipid metabolism disorders are well established. However, association of IR with hypertension is less covered. Current researches on insulin resistance and pathogenesis of hypertension are reviewed in this paper, which holds that traditional Chinese medicine treatment on IR in patients with hypertension has a good prospect.

Objective To assess the value of high-resolution ultrasonography in diagnosis of cubital tunnel syndrome. Methods Forty-two patients (43 elbows) initially diagnosed as cubital tunnel syndrome underwent ultrasonography (US), while 15 healthy contralateral elbows of these patients taken as self controls, and 15 healthy volunteers as normal controls underwent US of the ulnar nerve. The findings of US measurements were compared with that of intra-operative results and pre-operative electromyography. Results High-resolution US displayed changes and some etiological factors of cubital tunnel syndrome. The measurements of ulnar nerve at the proximal part of the compression were higher than those in the control groups. The cut-off point of cross-sectional area (CSA) and CSA tumefaction ratio was 0.11 cm~2 and 141.50%, respectively. The sensitivity of US was 92.86% compared with intra-operative results, and was 100% when combined with pre-operative electromyography. Conclusion High-frequency ultrasound can be used as an effective method to diagnose cubital tunnel syndrome.

Background and purpose:Recent researches have shown that Secreted Protien Acidic and Rich in Cysteine (SPARC) was closely related to tumor genesis, tumor progression and tumor metastasis. SPARC was highly expressed in malignant melanoma, glioma, meningioma, bladder cancer, lung cancer and prostate cancer, etc. In this study we investigated SPARC expression in hepatocellar carcinoma (HCC) and its signifi cance. Methods:RT-PCR was used to detect SPARC mRNA expression in cancer tissue samples and their adjacent liver tissue samples from 62 patients with hepatocellar carcinoma and 30 normal liver tissue samples, respectively. And the differential protein expression of SPARC between these groups was analyzed by immunohistochemistry (IHC). Results:SPARC mRNA was highly expressed in HCC(14.0?3.6) and in the adjacent liver tissue (6.8?1.8); compared with low expression of 2.7?0.9 in normal liver tissue, there were signifi cant differences among the three groups (p=0.000). SPARC positively stained was found in 54 of 62 patients with HCC and 4 of 30 normal liver tissue, there was significant difference between these two groups (P=0.000). SPARC immunohistochemical score was 21.5?4.8 in the carcinoma group; 11.3?3.6 in paracarcinoma group and 5.7?1.8 in the normal group, there were also significant differences among the three groups (P=0.000). The expression of SPARC protein was significantly upregulated with the progress of Enmondson pathological classification. There was obviously differences between Ⅰvs Ⅱ(P=0.029), and Ⅱ vs Ⅲ Ⅳ(P=0.008). There was more SPARC expression in the patients with metastasis of HCC (26/27, 96.3%) than that without metastasis(23/35, 65.7%)(P=0.004). Conclusion:SPARC mRNA expression and its protein were related to HCC histological differentiation and metastatic lymph node; SPARC is helpful to clinical evaluation of HCC.

Methods:30 Sprague-Dawley(SD) rats were randomly divided into 6 groups:sham operation group,model group,Naotaifang extract groups(low,middle,and high dosage) ,and Naofukang group. Some indexes were detected such as neurological scores,VEGF mRNA expression by RT-PCR,and the number of VEGF positive cells by immunohistochemical methods. Results:The symptoms in nervous function were improved in the Admin. groups,especially in the Naotaifang middle dosage group. The number of VEGF positive cells and VEGF PCR production in Naotaifng middle dosage group was higher than that in the model group. Conclusion:Naotaifang has neuroprotective effect against focal cerebral ischemic injury by improving the expression of VEGF.

This study is to prepare the pantoprazole sodium enteric-coated tablet which is compacted by pellets. The enteric-coated pantoprazole sodium pellets were prepared by fluid bed coating technology. The pantoprazole sodium enteric-coated tablets were prepared by direct compression of the enteric-coated pellets and suitable excipients. In vitro dissolution method and scanning electron microscope method were used for the observation of the drug release behavior before and after compression of the pellets. The optimized formulation is: the coating level is 55%, the plasticizer content is 20%, the ratio of Eudragit L30D-55/NE30D is 8 : 2, enteric-coated pellets/excipients (MCC/PPVP/PEG 6000 = 2 : 1 : 1) is 5 : 5, the enteric-coated tablets release in artificial gastric fluid in 2 h is less than 10%, while in artificial intestinal fluid in 1 h is more than 85%. The release behavior of pantoprazole sodium enteric-coated pellets-type tablet is quite well. And it may be used in industrial production.

One of the important approaches for further prolonging remission duration and eradicating minimal residual disease in acute leukemia is immunotherapy. Four kinds of immunotherapy for acute leukemia are under investigation: (1) monoclonal antibodies, among them, Mylotarg (cytotoxic antibiotic calicheamicin linked to CD33 Mab) is given for the treatment of refractory or relapsed acute myeloid leukemia and molecular relapse in acute promyelocytic leukemia with good results, Campath-1H (antiCD52 Mab) is administered in the treatment of prolymphocytic leukemia and Rituximab (anti-CD20 Mab) in B-PLL with high complete remission rates. Other Mabs under preclinical and clinical trials include anti-IL-2 receptor Mab for the treatment of acute T lymphocytic leukemia, anti-220 kD Mab-6G7 for acute leukemias, recombinant immune toxin BL22 (anti-CD22) for hairy cell leukemia and Mabs labeled with radio-isotopes for different types of acute leukemias; (2) adoptive cellular immunotherapy using cytokine-induced killer cell, alloreactive NK cells, allogeneic or autologous leukemic-specific CD8(+) cytotoxic T lymphocytes, and other immune effector cells; (3) cytokines and other immune modulators comprising IL-2, IL-12, GM-CSF, CD40L, FLT-3L and thalidomide and its derivatives; (4) leukemia vaccines of several different formulations including antigen-specific, leukemia cell-based, leukemia antigen-pulsed dendritic cell (DC) and leukemia-derived DC vaccines, the latter two formulations are more attractive. In conclusion, up to now, the most effective example of immunotherapy in acute leukemia is provided by the administration of Mabs, and the majority of other approaches in immunotherapy for acute leukemia although promising, need further studies.

ObjectiveTo investigate the distribution of human immunodeficiency virus-1 (HIV-1)subtypes and the relationship with transmission routes in Shenzhen city. MethodsThe epidemiological survey was conducted in 429 subjects with HIV-1 infection.Vein blood was collected and prepared with anticoagulation.Thereafter,the viral nucleic acid was extracted and subsequently amplified for HIV-1 env,gag genes by reverse transcription nested polymerase chain reaction. The viral sequences were analyzed using Mega software and compared with those in HIV database. The HIV-1 subtypes were confirmed and evolutionary tree was established. The gene discrete rate of different subtypes was calculated.ResultsFour hundred qualified samples were identified as CRF01_AE (n=207),CRF07_BC (n=115),CRF08 _BC (n=14),CRF02_AG (n=1),B (n=49) and C(n=14),respectively.CRF01_AE was the predominant subtype that was detected in the subjects with different transmission routes,such as homosexual contact,heterosexual contact,intravenous drug use and hospital-acquired infection. Among these,sexual contact was the most common route.There were nine cases infected with subtype B HIV-1 in 10 case who were blood borne. The gene discrete rate was more significant in subtype B HIV-1 compared to the other subtypes.According to the evolutionary tree analysis,the viruses under the same subtype formed the relatively independent clusters by different transmission routes. But some overlaps were observed as well. Conclusions Tbere are many HIV-1subtypes in HIV-1 infected subjects in Shenzhen, while the recombinant viruses present as the predominant form.Transmission routes are various with sexual contact as the most common route.Every subset distributes unevenly and forms its own characteristic.Overlap can be observed among the gene distribution of different HIV-1 subtypes.

Stem cells are crucial for embryonic development and in the maintenance of adult cellular homeostasis.Understanding the regulatory network of stem cells,including embryonic and adult stem cells,will allow us to learn the pathogenesis and possibly design novel approaches to treat many diseases (such as cancer and degeneration).The retinoblastoma (Rb) pathway controls cellular proliferation,differentiation and death.More and more evidences support an important role of Rb activity in the biology of stem and progenitor cells.Transiently inactivating Rb pathway might favor the expanding of functional stem cell populations,thus have values in the future stem cell applications.
