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.
6. Application of PD-1 inhibitor Camrelizumab in advanced malignancies
Medical Journal of Chinese People's Liberation Army 2020;45(6):672-679
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.

To investigate the clinical characteristics and angio-architecture features of patients with dural arteriovenous fistulas (DAVF).The clinical data of 48 patients with DAVF were analyzed retrospectively.All patients were diagnosed by digital subtract angiography and 43 cases were also examined by MRI.Patients were divided into the bleeding group and non-bleeding group,whose clinical features and angio-architecture were compared.Of 48 cases,13 patients demonstrated intracranial bleeding,and men were more common in bleeding group (M/F:10/3) than in non-bleeding group (M/F:15/20) (P =0.036).The Cognard scores of bleeding group and nou-bleeding group were 3.77 ±0.28 and 2.49 ±0.21,respectively (P =0.002) ; however,there was no significant difference in age and the number of feeding artery between two groups.The results indicate that male patients with high Cognard scores tend to intracranial bleeding.
