Wake-Promoting Effect of Bloodletting Puncture at Hand Twelve Jing-Well Points in Acute Stroke Patients: A Multi-center Randomized Controlled Trial / 中国结合医学杂志

OBJECTIVE@#To assess the effect and safety of bloodletting puncture at hand twelve Jing-Well points (HTWPs) in acute stroke patients with conscious disturbance.@*METHODS@#In this multi-center and randomized controlled trial, 360 patients suffered from ischemic or hemorrhagic stroke with conscious disturbance within 48 h from the onset of symptom were divided into bloodletting (180 cases) and control (180 cases) groups using a block randomization. Patients in both groups received routine Western medicine, and patients in the bloodletting group received additional bloodletting puncture at HTWPs on admission immediately before conventional treatment. The primary outcome measure was Glasgow Coma Scale (GCS) score and the secondary outcomes included blood pressure, respiratory rate and pulse rate. All variables were evaluated at baseline (before bloodletting), 0 (after bloodletting immediately), 15, 30, 50 and 80 min post bloodletting.@*RESULTS@#At 80 min post bloodletting, the proportion of patients with improved consciousness in the bloodletting group was greater than the control group (P0.05).@*CONCLUSION@#The bloodletting puncture at HTWPs was safe and could improve conscious levels of ischemic stroke patients, highlighting a first-aid intervention for acute stroke.

Small molecule proteomics quantifies differences between normal and fibrotic pulmonary extracellular matrices / 中华医学杂志(英文版)

BACKGROUND@#Pulmonary fibrosis is a respiratory disease caused by the proliferation of fibroblasts and accumulation of the extracellular matrix (ECM). It is known that the lung ECM is mainly composed of a three-dimensional fiber mesh filled with various high-molecular-weight proteins. However, the small-molecular-weight proteins in the lung ECM and their differences between normal and fibrotic lung ECM are largely unknown.@*METHODS@#Healthy adult male Sprague-Dawley rats (Rattus norvegicus) weighing about 150 to 200 g were randomly divided into three groups using random number table: A, B, and C and each group contained five rats. The rats in Group A were administered a single intragastric (i.g.) dose of 500 μL of saline as control, and those in Groups B and C were administered a single i.g. dose of paraquat (PQ) dissolved in 500 μL of saline (20 mg/kg). After 2 weeks, the lungs of rats in Group B were harvested for histological observation, preparation of de-cellularized lung scaffolds, and proteomic analysis for small-molecular-weight proteins, and similar procedures were performed on Group C and A after 4 weeks. The differentially expressed small-molecular-weight proteins (DESMPs) between different groups and the subcellular locations were analyzed.@*RESULTS@#Of the 1626 small-molecular-weight proteins identified, 1047 were quantifiable. There were 97 up-regulated and 45 down-regulated proteins in B vs. A, 274 up-regulated and 31 down-regulated proteins in C vs. A, and 237 up-regulated and 28 down-regulated proteins identified in C vs. B. Both the up-regulated and down-regulated proteins in the three comparisons were mainly distributed in single-organism processes and cellular processes within biological process, cell and organelle within cellular component, and binding within molecular function. Further, more up-regulated than down-regulated proteins were identified in most sub-cellular locations. The interactions of DESMPs identified in extracellular location in all comparisons showed that serum albumin (Alb) harbored the highest degree of node (25), followed by prolyl 4-hydroxylase beta polypeptide (12), integrin β1 (10), apolipoprotein A1 (9), and fibrinogen gamma chain (9).@*CONCLUSIONS@#Numerous PQ-induced DESMPs were identified in de-cellularized lungs of rats by high throughput proteomics analysis. The DESMPs between the control and treatment groups showed diversity in molecular functions, biological processes, and pathways. In addition, the interactions of extracellular DESMPs suggested that the extracellular proteins Alb, Itgb1, Apoa1, P4hb, and Fgg in ECM could be potentially used as biomarker candidates for pulmonary fibrosis. These results provided useful information and new insights regarding pulmonary fibrosis.

Observation on therapeutic effect of post-apoplectic unilateral sensory disturbance treated with wrist-ankle acupuncture / 中国针灸

<p><b>OBJECTIVE</b>To observe the clinical effect of wrist-ankle acupuncture combined with conventional acupuncture on post-apoplectic unilateral sensory disturbance.</p><p><b>METHODS</b>Eighty cases of acute cerebral apoplexy patients of unilateral sensory disturbance were randomly divided into an observation group and a control group, 40 cases in each one. In control group, the conventional acupuncture was applied at bilateral Fengchi (GB 20), and Jianyu (LI 15), Quchi (LI 11) and Waiguan (TE 5) etc. on the affected side. In observation group, wrist-ankle acupuncture was adopted in combination with conventional acupuncture. In wrist-ankle acupuncture, the needles were inserted from the Upper 1-6 and the Lower 1-6 on the affected side, and were remained for 5 to 6 h. The needles were punctured in the morning and removed in the afternoon. The clinical efficacy, the score in the sensory disturbance assessment as well as the changes in the limb sensory disturbance degree based on the patients' feelings were observed in two groups.</p><p><b>RESULTS</b>The total effective rate in observation group was 90.0% (36/40), which was superior to 75.0% (30/40) in control group (P < 0.05). The improvements were obtained in the total scores of the limb sensory function, superficial sensibility and cortical sensibility after treatment in either group (P < 0.05, P < 0.01), but there was no remarkably improvement in proprioception (both P > 0.05). All the scores above were improved much remarkably in observation group as compared with control group (all P < 0.05).</p><p><b>CONCLUSION</b>Wrist-ankle acupuncture combined with conventional acupuncture is the effective therapy for post-apoplectic unilateral sensory disturbance.</p>

Effects of androgen on the bone / 中华男科学杂志

Androgen is an anabolic steroid composed of 19 carbon atoms. As a sex hormone, it has far-ranging effects on many sites within the body, including bone metabolism. Androgen has important effects on bone development and homeostasis. It has been proved that the androgen receptor (AR) expresses in bone cells, which indicates that androgen has direct effects on bone cells. Furthermore there is convincing evidence that aromatization to estrogen is an important way of mediating the action of testosterone. Androgen not only plays an important role in gaining the peak bone mass and maintaining the bone mass, but also has a close correlation with aging-related bone loss.
