Objective: To observe the therapeutic efficacy of music electric stimulation of points in treating anxiety. Methods: By adopting a design of multi-centered randomized controlled trial (RCT), a total of 270 patients with anxiety were randomized into a treatment group and a medication group. The treatment group was intervened by music electric stimulation of points, while the medication group was intervened by oral administration of doxepin. The two groups were evaluated by using Hamilton anxiety rating scale (HAMA) and Chinese revised edition of self-rating anxiety scale (SAS-CR) before and after the intervention. The therapeutic efficacies were also compared. Results: The total effective rate was 93.6% in the treatment group versus 92.3% in the medication group, and the between-group difference was statistically insignificant (P>0.05). After the treatment, the aggregate scores of HAMA and SAS-CR were significantly changed in both groups (both P<0.001), and the inter-group differences were statistically insignificant (P>0.05). Conclusion: Music electric stimulation of points can produce equivalent efficacy in treating anxiety compared to doxepin. Thus, it can be taken as a choice in the treatment of anxiety.

OBJECTIVETo establish a primary culture method of rat testis Leydig cell.

METHODSThe primary rat Leydig cells were treated with or without 4 U/ml human chorionic gonadotropin (hCG), and testosterone in culture medium was detected by radioimmunoassay. The morphology and biological characteristics of Leydig cell were observed.

RESULTSThe culture cells were highly homogeneous, proliferative and had a high differentiation rate. The high purified Leydig cells were verified by their dynamic morphological changes and 3beta-hydroxysteroid dehydrogenase delta4-delta5 isomerase (3beta-HSD) histochemical staining. The testosterone secretion induced by hCG significantly increased (P < 0.05) 24 hours after inoculation than that induced without hCG in the control.

CONCLUSIONIt suggests that the Leydig cell cultured in vitro may secrete high concentration of testosterone, and this study laid the basis of androgen replacement therapy for partial androgen deficiency in aging male.

OBJECTIVETo explore the pathophysiological and biomechanical features of skeletal muscular injury for providing a rational basis for its treatment, prevention and rehabilitation.

METHODSIn 70 adult rabbits, the left tibialis anterior (TA) muscle was stretched to injury, while the right TA muscle served as control. Histological, enzymohistochemical and biomechanical changes were observed on days 0, 1, 2, 3, and 7 after injury. Cytochrome oxidase (CCO), acid phosphatase (ACP), ATPase, succinate dehydrogenase (SDH), malate dehydrogenase (MDH), NADH-diaphorase (NADHD), glutamatedehydrogenase (GDH), alpha-glycerophosphate dehydrogenase (alpha-GPD) and lactate dehydrogenase (LDH) were measured. The examined biomechanical parameters included maximal contractile force, ultimate load, length, energy absorption, tangent stiffness, and rupture site.

RESULTSPartial or complete rupture of TA muscle occurred near the muscle-tendon junction. There was an intense inflammatory reaction on day 1 and 2 after injury. Endomysium fibrosis and myotube formation were observed on day 3, and developed further on day 7. The activity of cell oxidases (CCO, ATPase, MDH, alpha-GPD, SDH, NADHD and GDH) showed a significant drop from day 0 to 2, and resumed with different levels on day 3. The increment of enzymatic activities continued on day 7 and the levels of NADHD and alpha-GPD reached to the levels of control muscle. Maximal contractile force was 70.17%+/-3.82% of controls immediately after injury, 54.82%+/-3.09% at 1 day, 66.41%+/-4.36% at 2 days, 78.39%+/-4.90% at 3 days and 93.64%+/-5.02% at 7 days. Ultimate load was 85.78%+/-7.54% of controls at the moment of injury, 61.44%+/-5.91% at 1 day, 49.17%+/-4.26% at 2 days, 64.43%+/-5.02% at 3 days, and 76.71%+/-6.46% at 7 days.

CONCLUSIONSEndomysium fibrosis and scar formation at the injured site are responsible for frequent recurrence of skeletal muscle injury. Recovery of tensile load slower than that of maximal contractile force may be another cause. Whether the injured muscle returns to normal exercise is mainly determined by the tensility on which the muscle-tendon can bear rather than the maximal contractile force.

OBJECTIVETo investigate the serum level of carboxy-terminal telopeptide of type I collagen (ICTP) and explore its correlation with MMP-2 and MMP-9 in patients with coronary artery disease (CHD).

METHODSA total of 103 CHD patients treated in our hospital between October, 2013 and May, 2014 were enrolled, including 39 with stable angina pectoris (SAP), 39 with unstable angina (UA), and 25 with acute myocardial infarction (AMI), with 38 non-CHD volunteers as the control group. The serum levels of ICTP, MMP-2, and MMP-9 were detected in all the subjects using enzyme-linked immunosorbent assay (ELISA).

RESULTSNo significant difference in serum levels of MMP-2, MMP-9, or ICTP was found between the control and SAP groups or between UA and AMI groups (P>0.05), but the latter two groups had significantly higher serum levels of MMP-2, MMP-9, and ICTP than the former two groups (P<0.05). Serum ICTP level was found to negatively correlated with the fibrotic area and positively with the lipid component in the plaques (P<0.05). Regression analysis revealed significant positive correlations of serum ICTP with MMP-2 and MMP-9 (P<0.05).

CONCLUSIONAn elevated serum ICTP level is indicative of the presence of unstable plaques in CHD patients. Serum ICTP is more strongly correlated with MMP-2 than with MMP-9, and can be used as a non-invasive marker for assessing vulnerable plaques in patients with acute coronary syndrome.

OBJECTIVETo study the preventive and therapeutic effects of recombinant IFN-alpha2b for nasal spray on SARS-CoV infection in Macaca mulata (rhesus monkey).

METHODSTen rhesus monkeys were divided into two groups, 5 in interferon group, and 5 in control group. Before and after SARS-CoV attack, the virus was detected in samples such as pharyngeal swab in all the two groups by Real-time PCR (RT-PCR) and virus isolation was performed.

RESULTSAfter virus attack, the level of SARS-CoV-specific IgG and neutralizing antibody were induced by SARS-CoV in the interferon group was weaker than in control group. Hematology items showed no apparent changes after virus attack in treated group. Through pathological examination, the morphology of the lung tissues of two Macaques in the treated group was normal, while the other three displayed the interstitial pneumonia with the thickened septum and infiltration with mononuclear cells. Among which, one monkey showed part of thickened septum fused with each other. These lesions in the interferon treated animals were similar to those seen in the animals in control group, but with smaller scope of pathological changes. No significant abnormity was detected in other organs.

CONCLUSIONRecombinant IFN-alpha2b could effectively interdict or weaken SARS-CoV injury in monkeys.

Aim To investigate the effectiveness and safety of alfentanil in general anesthesia.Methods In this study, a multicenter randomized double-blind con¬trolled study was conducted.A total of 352 subjects were selected and randomly assigned to fentanyl group (group A, n =176) and alfentanil group (group 15, n = 176).Anesthesia induction: intravenous midazolam 0.03 mg • kg-1 + fentanyl 25 p.g • kg"'(group A) or alfentanil 4 p,g • kg-1 ( group 15) + propofol 2 mg • kg"1 + rocuronium 0.8 mg • kg"1.Sevoflurane + fent¬anyl ( group A ) or alfentanil ( group B ) + rocuronium were used for anesthesia.The vital signs of patients re¬covery time and extuhation time, anesthesia-related complications and the use of related remedial drugs during anesthesia induction and maintenance were compared between the two groups.Results During the induction and maintenance period of anesthesia, alfentanil and fentanyl could equally effectively inhibit the stress response induced by endotracheal intubation and surgical stimulation.Alfentanil also showed more effective inhibition on stress response induced by endo¬tracheal intubation and surgical stimulation than that of fentanyl ( P < 0.05 ) .However, there was no signifi¬cant difference in the incidence of intraoperative hypo¬tension and hypertension and the time of anesthesia re¬covery and extubation between the two groups.Conclu¬sions Both alfentanil and fentanyl can effectively in¬hibit the stress response induced by surgical stimulation and could be safely used in general anesthesia in sur¬gery.Alfentanil has more advantages in maintaining the stability of blood pressure and heart rate during an¬esthesia induction and maintenance.

Volatile oil of traditional Chinese medicine （VOTCM） is a plant volatile component obtained through distillation or supercritical fluid extraction. The volatile oil is rich in terpenes and phenylpropanoids， with many different effect. It is not only widely used in healthcare products， but also has a variety of pharmacological effect， such as analgesia， antioxidant， antibacterial， anti-inflammatory， anti-tumor effect. Malignant tumor is an important threat to human health. At present， the drugs commonly used in clinical treatment of tumors are expensive with certain toxic and side effect. Although new treatment technologies are also being promoted step by step， they have higher treatment costs than traditional chemotherapies， and the long-term efficacy remained to be further confirmed. The effect of volatile oil of traditional Chinese medicine（TCM） on cancer is receiving more and more attention. In particular， it has a significant inhibitory effect on lung， liver， colon， and stomach cancer. Specifically， it can not only reduce the side effect of chemotherapy drugs， but also effectively prolong or stop the tumor recurrence， with special effects in treatment and adjuvant treatment. At the same time， various anti-tumor mechanisms of volatile oils have been discovered， such as inducing tumor cell apoptosis， inhibiting tumor blood vessel formation， inhibiting tumor cell proliferation， inducing tumor cell differentiation， interfering with multidrug resistance， and regulating the body's immune function. However， there are still some problems in the basic research， achievement transformation， and product development of volatile oil of TCM， which restricts its clinical and daily application. This paper summarizes the antitumor mechanism of volatile oil of TCM by consulting relevant domestic and foreign literatures， analyzes the current situation of volatile oils， and proposes improvement directions for its problems and development， in the expectation of laying the foundation for the research of volatile oil of TCM in anti-tumor research.

OBJECTIVE: To compare the clinical efficacy and safety of oral administration of Buxue Yimu Pills (BYP, ), ferrous sulfate (FS), and the combination of BYP and FS on gynecological anemia, and investigate the mechanisms using network pharmacology. METHODS: A randomized, controlled, multi-center clinical trial was conducted. Totally 150 patients with hemoglobin of 70-110 g/L due to gynecological conditions were recruited and randomized (using the block randomization method) into Buxue Yimu Pills group (24 g/d), oral iron group (FS Tablets, 0.9 g/d), and combined treatment group (BYP, 24 g/d plus FS Tablets, 0.9 g/d), 50 patients in each group. At the enrollment and 4-week treatment, complete blood count, serum iron indexes were evaluated. Adverse events, liver and renal functions, as well as blood coagulation were observed. Network pharmacology was conducted to identify the active ingredients and explore the potential mechanisms of BYP. RESULTS: Ten (20%) and 7 (14%) participants discontinued the therapy due to gastrointestinal symptoms in oral iron and combination treatment groups. All 3 groups showed elevated hemoglobin. The patients in the iron group exhibited typically elevated in serum iron and ferritin and decreased in total iron-binding capacity. No change in iron indexes was observed in BYP group. The patients in the combination treatment group neither showed significant changes in serum ferritin nor total iron-binding capacity. No significant adverse reactions were observed in the BYP group. The network pharmacology identified 27 bioactive compounds and 145 targets of BYP on gynecological anemia. Biological processes and pathways including regulation of inflammation, hormone, angiogenesis and hemostasis, response to decreased oxygen levels, effects on myeloma cell, and response to metal ions were identified. CONCLUSION BYP contributes to the practical improvement on gynecological anemia potentially through multi-target mechanisms and optimized iron re-distribution. (Trial registration: No. NCT03232554).
