ObjectiveTo observe the effect of auricular point sticking plus acupressure on blood pressure and lipid in hypertension patients with a dampness-phlegm constitution.MethodThe eligible subjects were randomized into antreatment group of 38 cases and a control group of 40 cases. The control group was intervened by conventional medication, while thetreatment group was additionally intervened by auricular point sticking plus acupressure. Before and after intervention, the blood pressure and lipid levels [total cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL), low density lipoprotein (LDL)] were detected. ResultAfter intervention, the blood pressure, TC and TG levels were decreased in thetreatmentgroup (P<0.05,P<0.01), while the changes of HDL and LDL were statistically insignificant (P>0.05).ConclusionAuricular point sticking plus acupressure can somehow improve the blood pressure, TC and TG of hypertension patients with a dampness-phlegm constitution.

Objective To evaluate the application value of polymerase chain reaction (PCR)-fluorescence probe method in identifying genotypes of hepatitis C virus (HCV).Methods One hundred and sixty six serum samples from patients with chronic HCV infection were collected nationwide from March to June 2016.HCV Core-E1 gene region was amplified and sequenced by nested reverse transcription-PCR (RT nested-PCR)and genetic subtypes were analyzed by phylogenetic tree,meanwhile HCV genotypes were also determined by PCR-fluorescent probe method.Kappa test was used to compare the consistency of two methods.Results Among 166 samples detected by RT nested-PCR,the genotype of 66 samples (39.8%) was 1 b,34 (20.5%)was 2a,16 (9.6%)was 3a,27 was 3b (16.2%),23 (13.9%)was 6a.Two samples with 3b genotype detected by RT nested-PCR were identified as 1 b by PCR-fluorescent probe.The consistency rate of two methods was 98.7% (164 /166),there was no significant difference between two methods (χ2 =0.0492,P >0.05).Conclusion PCR-fluorescence probe method can accurately identify HCV genotypes and can be used in clinic.

The binding function of EGF1 domain peptide with tissue factor (TF) and its ability of triggering coagulation were explored. The TF expression model in vitro was established by lipopolysaccharide induction. The affinity of EGFP-EGF1 and TF expressing cells was analyzed by fluorescence microscopy and flow cytometry (FCM). The affinity of EGFP-EGF1 and rat soluble TF was quantitated by surface plasmon resonance (SPR). The ability of EGFP-EGF1 in triggering coagulation was tested by prothrombin time assay. The FCM results showed recombinant factor VII (rFVII) could definitely depress the integration of EGFP-EGF1 with recombinant TF (rTF) (68.65%+/-3.86% vs 57.98%+/-4.71%, P<0.01). The SPR results indicated the association constant ka of EGFP-EGF1 proteins was higher than rFVII (8.29+/-1.39 vs 3.75+/-0.32, P<0.01). However, the EGFP-EGF1 protein lost the activity of triggering coagulation as compared with blood plasma of normal SD rats (56.8+/-3.2 s vs 17.8+/-3.4 s, P<0.01). It was concluded that the rat EGF1 peptide could specifically bind to TF without the ability of triggering coagulation. EGF1 peptide may be a good target head for delivering drugs to TF in anticoagulation therapy.

This study examined the association of a common polymorphic allele (25G) of the low-density lipoprotein receptor-related protein1 (LRP1) gene with myocardial infarction (MI). The genotypes of LRP1 25CG (rs35282763) were determined in 347 MI patients and 347 age- and sex-frequency-matched controls from an unrelated Chinese Han population. Factor VIII (FVIII) levels were measured in the MI patients and controls by chromogenic assay and enzyme-linked immunosorbent assay (ELISA). The results showed that LRP1 25CG (rs35282763) genotype distribution did not differ significantly between patients (n=206 for 25CC, n=122 for 25CG) and controls (n=191 for 25CC, n=126 for 25CG; P>0.05). The 25G allele was not associated with a reduced risk of MI (P>0.05). Further stratifications for age, sex, and other cardiovascular risk factors did not affect the negative findings. It was concluded that the presence of the G allele at the 25CG (rs35282763) polymorphism of the LRP1 is not associated with a reduced risk of MI, and genotyping for LRP1 25CG (rs35282763) polymorphism is not useful in assessing the individual risk of MI.

Objective To compare the efficacy of different models of attention rehabilitation on attention deficits after acquired brain injury. Methods According to the training models, 47 patients with attention deficits were randomly assigned to 3 groups: computer-assisted training group(n=16), face-to-face training group(n=21) and control group(n=10). The training groups were given attention training once a day which sustained 30 minutes for 6 weeks. All patients were tested with the Montreal Cognitive Assessment (MoCA) and the Loewenstein Occupational Therapy Cognitive Assessment Battery (LOTCA) before and 6 weeks after the rehabilitation. Results The performance of both the computer-assisted training group and the face-to-face training group significantly improved (P<0.05). The various of the scores was the most in the computer-assisted training group among them (P<0.05). Conclusion The computer-assisted training is a high-effective method for attention deficits.

Objective:To compare the postoperative efficacy and complications of frontalis suspension and levator resection in the treatment of blepharoptosis.Methods:According to the Cochrane systematic review method, we searched PubMed, Medline, Cochrane Library, Wanfang database, VIP Database, and China Knowledge Network database. The randomized and non-randomized controlled trials for comparing frontalis suspension and levator resection in the treatment of blepharoptosis were included. Revman 5.3 Meta analysis software was used.Results:A total of 13 clinical trials were involved in this study, including 1308 patients. Frontalis suspension was performed in the experimental group and levator resection was performed in the control group. The OR value of postoperative efficacy between the 2 groups was 2.91, 95% CI (1.57-5.39), P<0.01, the difference was statistically significant. Postoperative lagophthalmos after frontalis suspension was better [ MD=-1.05, 95% CI (-1.43--0.68), P<0.01], the difference was statistically significant. The OR value of undercorrection between the 2 groups was 0.24, 95% CI(0.16-0.36), P<0.01, the difference was statistically significant. Conclusions:The postoperative efficacy after frontalis suspension is higher. Postoperative complications after frontalis suspension are less.

Objective To compare the efficacy of different rehabilitation models on acalculia after acquired brain injury. Methods 113 cases were randomly assigned to 3 groups: control group(n=37), computer-assisted training group(n=38) and face-to-face training group(n=38). The control group just received cognitive dysfunction evaluation. The training groups received cognitive rehabilitation training 5 days a week and 30 minutes a day which sustained for 6 weeks. And 33 patients were selected to prolong for 12 weeks. They were evaluated with Revised EC301Calculation and Number Processing Battery in Chinese version (EC301-CR) at the beginning, the 6th week point and the 12th week point respectively. Results 6-week after treatment, The performance of both the computer-assisted training group and face-to-face training group significantly improved(P<0.001); It showed that computer-assisted group>face-to-face group>control group(P<0.001) both 6 weeks and 12 weeks latter. Significant negative correlation was found between age and performance of EC301-CR(P<0.05).Conclusion The effect of computer-assisted training on acalculia is superior to face-to-face training; The first 6 weeks of training is the best period for rehabilitation; The younger the patient is, the better results are.

Patients with severe or critical coronavirus disease 2019 (COVID-19) are at high risk of death primarily due to respiratory failure caused by the cytokine storm in pulmonary tissues. The treatment response of these patients remains limited. Recently, low-dose radiation therapy (LDRT) has been clinically adopted to treat severe or critical COVID-19 patients in multiple medical centers abroad, indicating high feasibility and effectiveness. However, the mechanism and optimal radiation dose are still incompletely clear. This paper reviews the radiobiological mechanism, effectiveness, adverse reactions, and radiotherapy dose of LDRT in the treatment of severe or critical COVID-19 patients, aiming to better understand the clinical benefits and adverse reactions of LDRT.
