Clinical study of modified Ganmai Dazao decoction in the treatment of yang deficiency climacteric depression and observe the effects of modified Ganmai Dazao decoction on neuroendocrine system in patients with yang deficiency climacteric depression. 86 cases were randomly divided into treatment group treated with modified Ganmai Dazao decoction and control group treated with Deanxit. The curative effect was evaluated with Hamilton's depressive scale (HAMD) and pittsburgh sleep quality scale (PSQI) before and at the end of the two and four weeks of the treatment, the serum levels of serotonin (5-HT), norepinephrine (NE), estradiol (E2), follicle stimulating hormone (FSH), luteotropic hormone (LH) were detected before and after the four weeks of the treatment The results showed that the total effective power of treatment group was 88.4% and the total effective power of control group was 81.4% after four weeks interference, with insignificant difference between the two groups. After two and four weeks of the treatment, the score of HAMD decreased remarkably in both groups (P < 0.01), with insignificant difference between the two groups in same phase. After two and four weeks of the treatment, the total score of PSQI decreased remarkably in both groups (P < 0.05), with significant difference between the two groups after four weeks (P < 0.01). After four weeks of treatment, the serum levels of 5-HT and NE increased (P < 0.01), with insignificant difference between the groups. After four weeks of treatment, the serum levels of E2 increased obviously (P < 0.05), the levels of FSH decreased obviously (P < 0.05), the levels of LH decreased insignificant, with insignificant difference between two groups. This study indicates that modified Ganmai Dazao decoction has obvious therapeutic effects in the treatment of climacteric depression, and showed equivalent efficacy with Deanxit, and modified Ganmai Dazao decoction has better effect on improving the sleep quality in patients than Deanxit, the effect of improved clinical symptoms may be through adjusted levels of 5-HT, NE, E2, FSH and LH of climacteric depression.

OBJECTIVETo evaluate the neuroprotective effect of tetramethylpyrazine (TMP) against focal cerebral ischemic injury in rats with diffusion-weighted magnetic resonance imaging (DWMRI).

METHODSRat models of focal cerebral ischemic injury were established in 16 male SD rats. They were randomly divided into the TMP group and the control group, eight in each group, and pretreated with TMP and normal saline respectively before modeling. Change of infarcted cerebral focus was observed with DWMRI at 1, 2, 6, 12 and 24 hrs after infarction, and the infarction volume (IV) at 24 hrs after modeling was estimated by triphenyltetrazolium chloride (TTC) stain.

RESULTSThe IV in all time points observed in the TMP group with DWMRI was significantly smaller than that in the control group (P<0.01). Compared with that at 1 hr after infarction, in the control group at 2, 6, 12 and 24 hrs after modeling, the IV enlarged by 13.3%, 29.7%, 50.3% and 57.3% respectively, while that in the TMP group 9.9%, 21.3%, 37.1% and 40.5% respectively. The cerebral IV estimated by TTC stain 24 hrs after modeling was larger than that estimated by DWMRI.

CONCLUSIONTMP pretreatment before modeling was effective in protecting brain against cerebral ischemic damage in rats. DWMRI dynamic scanning observation has important significance in observing the cerebral ischemic developing process and evaluating the effectiveness of brain protective measures.

OBJECTIVETo study the antiangiogenetic and tumor inhibitory effects of endostatin (Es) by intratumoral versus intravenous administration combined with adriamycin (Adm) for treatment of transplanted tumor in mice.

METHODSForty mice were subjected to subcutaneous implantation of H22 cells and randomly divided into 4 groups by the body weight when the tumor diameter reached 1 cm, namely the control group (with intratumoral and intravenous injection of normal saline), Es intratumoral group (with intratumoral injection Es and intraperitoneal Adm injection), Es vein group (with intravenous Es injection and intraperitoneal Adm injection), and Adm group (with intratumoral saline injection and intraperitoneal Adm injection). The tumor volumes and tumor inhibition rates were calculated, and the expression of vascular endothelial growth factor (VEGF) and the microvessel density (MVD) of the tumors were examined, with the survival time of the mice also observed.

RESULTSThe tumor volume was smaller in Es intratumoral group than in the other groups (P<0.05). The expression of VEGF and M VD in Es intratumoral group was significantly decreased as compared with that in the other groups (P<0.05). The survival time was significantly longer in Es intratumoral group and Es vein group than in the other groups (P<0.05), but showed no significant difference between Es intratumoral group and Es vein group (P>0.05).

CONCLUSIONIn combination with Adm regimen, Es given intratumoral injection produces better effect than intravenous Es injection against angiogenesis and tumor growth, no significant difference can be found in the survival time between them.

Pyronaridine and artesunate have been shown to be effective in falciparum malaria treatment. However, pyronaridine is rarely used in Hainan Island clinically, and artesunate is not widely used as a therapeutic agent. Instead, conventional antimalarial drugs, chloroquine and piperaquine, are used, explaining the emergence of chloroquine-resistant Plasmodium falciparum. In this article, we investigated the sensitivity of P. falciparum to antimalarial drugs used in Hainan Island for rational drug therapy. We performed in vivo (28 days) and in vitro tests to determine the sensitivity of P. falciparum to antimalarial drugs. Total 46 patients with falciparum malaria were treated with dihydroartemisinin/piperaquine phosphate (DUO-COTECXIN) and followed up for 28 day. The cure rate was 97.8%. The mean fever clearance time (22.5+/-10.6 hr) and the mean parasite clearance time (27.3+/-12.2 hr) showed no statistical significance with different genders, ages, temperatures, or parasite density (P>0.05). The resistance rates of chloroquine, piperaquine, pyronarididine, and artesunate detected in vitro were 71.9%, 40.6%, 12.5%, and 0%, respectively (P<0.0001). The resistance intensities decreased as follows: chloroquine>piperaquine>pyronarididine>artesunate. The inhibitory dose 50 (IC50) was 3.77x10(-6) mol/L, 2.09x10(-6) mol/L, 0.09x10(-6) mol/L, and 0.05x10(-6) mol/L, and the mean concentrations for complete inhibition (CIMC) of schizont formation were 5.60x10(-6) mol/L, 9.26x10(-6) mol/L, 0.55x10(-6) mol/L, and 0.07x10(-6) mol/L, respectively. Dihydroartemisinin showed a strong therapeutic effect against falciparum malaria with a low toxicity.

Objective To study the optimal waist circumference (WC) cut-off values for identifying metabolic risk factors in middle-aged and elderly subjects in Shandong Province of China.
Methods A total of 2 873 men and 5 559 women were included in this cross-sectional study. Metabolic syndrome (MetS) was diagnosed according to the definition of Chinese Diabetes Society in 2004. The relation between WC and MetS was analyzed by multivariate logistic regression analysis. The optimal WC cut-off values were identified using the area under the ROC curve and the different diagnostic criteria for central obesity were compared.
Results The WC was the risk factor for MetS independent of BMI, blood glucose, blood lipid, and blood pressure. The optimal WC cut-off value was 83.8 cm and 91.1 cm for identifying MetS in women and men, respectively. Compared with 80 cm and 85 cm for women and men, 85 cm and 90 cm had a higher Youden index for identifying all metabolic risk factors and MetS in women and men.
Conclusion The appropriate WC cut-off value is 85 cm and 90 cm for identifying central obesity and MetS in women and men in Shandong Province of China.

Chronic refractory wound (CRW) is one of the most challengeable issues in clinic due to complex pathogenesis, long course of disease and poor prognosis. Experts need to conduct systematic summary for the diagnosis and treatment of CRW due to complex pathogenesis and poor prognosis, and standard guidelines for the diagnosis and treatment of CRW should be created. The Guideline forthe diagnosis and treatment of chronic refractory wounds in orthopedic trauma patients ( version 2023) was created by the expert group organized by the Chinese Association of Orthopedic Surgeons, Chinese Orthopedic Association, Chinese Society of Traumatology, and Trauma Orthopedics and Multiple Traumatology Group of Emergency Resuscitation Committee of Chinese Medical Doctor Association after the clinical problems were chosen based on demand-driven principles and principles of evidence-based medicine. The guideline systematically elaborated CRW from aspects of the epidemiology, diagnosis, treatment, postoperative management, complication prevention and comorbidity management, and rehabilitation and health education, and 9 recommendations were finally proposed to provide a reliable clinical reference for the diagnosis and treatment of CRW.
