ObjectiveTo observe the therapeutic efficacy of warm needling plus Chinese medicinal fumigation and rehabilitation training in treating post-stroke shoulder pain.MethodSixty eligible patients were randomized into a treatment group (warm needling plus Chinese medicinal fumigation and rehabilitation) and a control group (rehabilitation training), 30 casesin each group. The Visual Analogue Scale (VAS), Fugl-Meyer Assessment Scale (FMA) and Barthel Index (BI) were respectively used to evaluate pain intensity, upper-limb motor function and activities of daily living, and the clinical efficacies were compared between the two groups.ResultAfter 30-day treatment, the improvements of shoulder pain intensity, upper-limb motor function and activities of daily living in the treatment group were more significant than that in the control group (P<0.05). There were no adverse events happened in the two groups.ConclusionWarm needling plus Chinese medicinal fumigation and rehabilitation training can effectively and safely mitigate shoulder pain, improve upper-limb motor function, and enhance the activities of daily living, and its therapeutic efficacy is superior to that of the control group.

Objective In order to enhance the understanding of Churg- Strauss syndrome, the clinical manifestations and the pathological features of 15 patients were reviewed. Methods The clinical and patho- logical findings of 15 patients with Churg- Strauss syndrome admitted to Peking Union Medical College Hospi- tal were retrospectively analysed. Results In 15 cases, the initial clinical manifestations were poly- mononeu- ropathy, gastrointestinal disorders and skin lesions. Peripheral eosinophilia was significant in all cases. Biopsies were taken in all cases. The typical pathological features usually demonstrated in diffiferent stage of the dis- ease. Conclusions If a patient shows a clinical manifestation of fever, skin lesions, neuropathy, abdominal pain and diarrhea, as well as eosinophilia in peripheral blood, the diagnosis of Churg- Strauss syndrome should be considered. It is necessary to take biopsies from several sites at different time.

Objective:To investigate the effect of metformin and arsenic trioxide on KG1a cells proliferation of acute myeloid leukemia and its possible mechanism.Methods:CCK-8 method was used to detect the killing effect of metformin,arsenic trioxide and combined application on KG1a cells.Annexin V-FITC/P1 Dual Stain Flow Cytometry was used to detect the effect of combined application on apoptosis of KG1 a cells.Western blot was used to detect the expression of intracellular apoptosis-,autophagy-related protein.Results:Metformin and arsenic trioxide alone or in combination could inhibit the proliferation of KG1 a cells and induce apoptosis of KG1 a cells,and the proliferation inhibition rate and apoptosis rate in the combined drug group were higher than those in the drug group alone(P＜0.05).The combination of drugs induced upregulation of Caspase 8 protein and P62 protein expression and was higher than that in the drug group alone(P＜0.05).Conclusion:Metformin can synergize with arsenic trioxide to kill KG1a cells,and its mechanism of action may be related to inducing apoptosis and enhancing autophagy.

Objective: To interview the role of CGRP to hepatic microcirculation in acute liver injury induced by coneanavalin A(Con A). Methods: Sixty Kunming rats were divided into three groups randomly(n=20), acute liver injury was established by injection with 20 mg/kg Con A through the tail vein. A saline control group was established by injection with saline. In CGRP-administered group, CGRP was given to rats 30 min before Con A injected. Ten mice in each group were used to observe the average liver blood flow volume and concentration by laser-doppler flow-instrument, and the other ten rats were observed the hepatic microcirculation velocity in vivo by an inverted microscope. Liver damage was assessed by histological evaluation after the rat had been killed. Results: Compared to the injury group, the average liver blood flow volume and velocity were significantly increased in CGRP-administered group, meanwhile, the pathological injury was markedly alleviated, whereas the blood concentration was almost the same. Conclusion: CGRP can decrease the dysfunction of hepatic microcirculation by means of improving the tissue perfusion, and alleviate the pathological damage during acute liver injury.

The microstructure of cationic cyclopeptide (TD-34) treated Caco-2 cell membrane was observed, and we discussed the relationship between membrane structure and insulin transmembrane permeability. Atomic force microscope (AFM) was used to observe living cell membrane in air condition and tapping mode. Results showed that the surface of Caco-2 cell membrane treated with TD-34 lost its smoothness and nearly doubled its roughness. Apparent permeability coefficients (P(app)) of insulin in Caco-2 cell monolayers increased 2.5 times. In conclusion, AFM can be used to observe microstructure of cationic cyclopeptide treated cell membrane and cationic cyclopeptide enhanced insulin delivery across Caco-2 cell membrane by increasing membrane fluidity.

AIMTo investigate the role of serine/threonine protein phosphatases in regulation of cell signal transduction on voltage-dependent sodium channels in rat trigeminal ganglion (TRG) neurons. METHODSWhole-cell patch clamp techniques were used to record the total sodium current (INa-T) and the tetrodotoxin-resistant sodium current (INa-TTX-R) before and after okadaic acid, a potent inhibitor of the serine/threonine protein phosphatases 1 and 2A, perfusion on adult rat TRG neurons. RESULTS1μmol*L-1 okadaic acid inhibited INa-T by (20±13)% (n=9, P<0.05) and INa-TTX-R by (4±3)% (n=6, P<0.05), respectively. The inhibition on INa-T was significantly greater than that on INa-TTX-R (P<0.05). Furthermore, 1μmol*L-1 okadaic acid produced significant 3-4 mV hyperpolarizing shifts in the conductance-voltage curves of INa-T, while it had no effect on that of INa-TTX-R. CONCLUSIONThe serine/threonine protein phosphatases take part in the regulation of total and TTX-R sodium channels on rat TRG neurons. In addition, small-diameter TRG neurons express various voltage-gated sodium channel with different sensitivity to okadaic acid.

This paper systematically introduces the standardization management system of medical equipment and some effective methods in hospital from 7 aspects such as the concept of medical equipment standardization,basic ideas,current management situation,fundamental methods,main measures,main effectiveness and recommendations.It emphasizes the necessity to strengthen the standardization of medical equipment in hospital under the new period and new condition.Personnel,equipment,environment and management should be gotten the optimum combination in order to maintain the hospital overall strength and competition.Through this way it can make medical equipment enter into a well-ordered cycle of quality,efficiency and benefit.

Objective To study the value of heart-type fatty acid-binding protein(H-FABP)for the early diagnosis of blunt cardiac injury(BCI).Method A prospective stuay was carried out in 42 patients,who suffered from blunt thoracic injury and were admitted from January 2007 to June 2008,and another42 heathy individuals in the health center of the Shanghai Fifth Hospital were recruited as control.Serum H-FABP,cTn Ⅰ and Myo levels of both healthy individuals and petients at 3,6 and 12 hours after trauma were measured by using ELLSA.Serum cTn Ⅰ levels was taken as a golden standard for the diagnosis of BCI.Accroding to serum cTn Ⅰ levels.42 patients with blunt thoracic injury were divided into group of patient with myocardial damage(13 patients)and group of patients without(29 patients).The receiver operating characteristic curves(ROC)of H-FABP and cTn Ⅰ in the diagnosis of BCI drawed at 3,6 and 12 hours after trauma,respectively,and the areas under curve(AUC)of ROC were compared.The values of H-FABP and cTn Ⅰ for diagnosing at 3,6 and 12 hours after trauma were analyzed Differences in serum H-FABP,cTn Ⅰ and Myo concentrations between groups were compared by Kruskal Wallis tegt.The delong.clarkepearson test was used to compare the areas under the ROC curves.Results AUCH-FABP and AUCcTn Ⅰfor diagnosing BCI at 3 hours after trauma were 0.9257 and0.6844,respectively,and AUCH-FABF was significantly more than AUCcTn Ⅰ(P=0.0125).AUCH-FABP,was significantly less than AUCcTnⅠ(0.9841 vs0.8276,P=0.0278)for diagnosing BCI at 12 hours after trauma.There was no significant difference in diagnosing BCI between AUCH-FABp and AUCcTn Ⅰat 12 hours after trauma(0.9655 vs.0.9125,P=0.2609).Conclusions H-FABP is valuabe in the early diagnosis of BCI,and its sensitivity is higherthanthat of cTnⅠ in diagnosing BCI at 3 hours after trauma.
