OBJECTIVEEstablished with amphotericin B perforated patch-clamp technique, to study the electrophysiological properties of calyx synapses.

METHODSIn the present experiments, we studied the application of perforated patch clamp technique on the calyx synapses of mice with Amphotericin B.

RESULTSThe use of Amphotericin B significantly slowed down the decay of channel currents and the optimum concentration was 400 microg/ml.

CONCLUSIONThe syudy developed a stable of perforated patch clamp whole cell recording technique, could be more effecitve, more real reaction neurons electrophysiological characteristics of the channel current. Our work might provide the basic information to future users studying the signal transmission and regulation of auditory system of rodents.

Objective To evaluate the clinical efficacy of cutaneous scraping and cupping therapy for the treatment of hyperplasia of mammary glands. Methods Eighty patients with hyperplasia of mammary glands were randomized into test group(42 cases) and control group(38 cases). Both groups were given conventional basic treatment including psychological counseling and oral use of Chinese patent medicine, and the test group additionally received cutaneous scraping and cupping therapy on acupoints of Xuanji(CV21), Danzho ng (CV17), Jianjing(GB21), Kufang(ST14) , Tianzhong(SI11), Dazhui(GV14), and Ashi(focus of mammary mass and pain). The scores of pain visual analog scale(VAS) and World Health Organization Quality of Life Scale Brief Version(WHOQOL-BREF) were observed, and the clinical efficacy of the two groups was evaluated. Results (1) The total effective rate of the test group was 88.10%, and that of the control group was 65.79%, the inter-group difference being statistically significant (P<0.01). (2) After treatment, VAS scores of the test group were decreased obviously(P<0.01), and the control group showed a decreasing trend(P>0.05). Test group had better effect on improving VAS scores than the control group(P<0.05).(3) After treatment , the scores in physiological dimension of WHOQOL-BREF were much increased(P<0.05), and the changes in the scores of other dimensions were not obvious(P>0.05). The control group showed no obvious changes in the scores of each dimension of WHOQOL-BREF before and after treatment(P>0.05). The inter-group comparison showed that the test group had better effect on improving the scores in physiological dimension of WHOQOL-BREF (P<0 . 05). Conclusion Cutaneous scraping and cupping therapy is effective on relieving pain and improving QOL of patients with hyperplasia of mammary glands.

0.05).The death rate of cases with pneumonia combined with ascites was higher than that of cases with ascites only(?2=4.894,P=0.027) and cases without ascites and infections(?2=9.260,P=0.002).Unfavorable prognosis was found in cases with Enterococcus faecium isolated before OLT.CONCLUSIONS Severe lung infection before OLT is one of the main reasons of death.It is important to grasp characteristics of infection,evaluate risk fully,control infections and screen cases strictly before OLT to improve survival rate.

With the remarkable achievements made in the treatment targeted at tumor immune checkpoints, more and more new immunotherapy drugs have been applied to the malignancies treatment. Camrelizumab (AiRuiKa) is a novel human immunoglobulin G4 (IgG4) monoclonal antibody (mAb), which can target the programmed death 1 (PD-1) and block its binding to the programmed death ligand 1 (PD-L1), so as to restore the body's immune function and achieve anti-tumor effect. The drug was officially approved by National Medical Products Administration (NMPA) on May 29, 2019 for use in patients with recurrent or refractory classical Hodgkin's lymphoma (cHL) who are treated with at least second-line systemic therapy. In addition, the drug showed good anti-tumor activity in esophageal squamous cell carcinoma (ESCC), hepatocellular carcinoma (HCC), nasopharyngeal carcinoma (NPC), non-small cell lung cancer (NSCLC), and gastric cancer (GC) and gastroesophageal junction cancer (EGJC). The research progress of camrelizumab on mechanism of action, pharmacodynamics and pharmacokinetics, clinical studies, adverse reactions etc. were reviewed in present paper.

OBJECTIVETo observe the effect of hallux-trampling (HT) combined with Yaotongling suppository (YS) on the microcirculation at waist region and lower limbs in treating patients with lumbar intervertebral disc prolapse (LIDP), and to preliminarily explore its mechanism.

METHODSAdopting randomized, double-blinded medicine and single-blinded manipulation controlled method, 108 patients with LIDP of cold-accumulation and blood-stasis syndrome were assigned equally to 3 groups in random. Group A was treated with HT plus YS, Group B treated with HT plus placebo suppository, and Group C treated with YS plus mock HT. After 2-week treatment, the changes in score of symptoms and signs as well as the microcirculation at various site-points of waist and lower limbs were observed before and after treatment.

RESULTSThe total scores of symptoms and signs after treatment in Group A, B and C was 7.340 +/- 4.627, 9.543 +/- 4.745 and 10.086 +/- 4.631 respectively, which was significantly lowered as compared with those before treatment respectively (P < 0.05). Significant difference of microcirculation between pre- and post-treatment was shown at all site-points in Group A and B (P < 0.05), but only shown at the site-points of lower limbs in Group C, so significant difference (P < 0.05) was shown when compared the microcirculation in Group A or B with that in Group C (P < 0.05).

CONCLUSIONHT combined YS in treating LIDP could markedly improve the microcirculation at waist and lower limbs to correct the nutritional disturbance of nerve root, and the improvement of microcirculation is correlated with the changes of clinical symptoms and signs.

Objective To investigate the effects and the mechanism of tirofiban administration in myocardial ischemical reperfusion injury(MIRI) in patients with acute myocardial infarction(AMI) undergoing primary percutaneous coronary intervention(PCI). Method The study included 158 STEMI Patients who accepted primary PCI therapy and were randomly (random number) divided into two groups: tirofiban administration group and control group. Incidence of MIRI during PCI, Correct TIMI frame count(CTFC), ST segment resolution(STR), peak value and peak time of MB isoenzyme of creatine kinase( CK-MB), and incidence of major adverse cardiac events (MACE) during 30 days postoperation in both groups were measured. Results Tirofiban administration group was superior to control group in terms of incidence of MIRI, CTFC, STR, peak value and peak time of CK-MB, and incidence of MACE during 30 days postoperation (P < 0.05). Multiple factor logistic regression analysis indicated that intravenous tirofiban administration before primary PCI was the independently protective factor for MIRI. Conclusions Intravenous tirofiban administration in patients with STEMI before primary PCI can significantly decrease the incidence of MIRI,reduce myocardial damage and improve the prognosis.
