OBJECTIVETo observe the clinical efficacy differences among warming-promotion acupuncture, regular acupuncture and psychological care for post-earthquake depression.
METHODSNinety cases of post-earthquake depression in Gansu province were randomly divided into a warming-promotion acupuncture group, a regular acupuncture group and a care group, 30 cases in each one. The psychological treatment was applied in the care group; the regular acupuncture at Baihui (GV 20), Sishencong (EX-HN 1)), Fengchi (GB 20), Shenmen (HT 7), Yang-lingquan (GB 34), Taichong (LR 3) and Sanyinjiao (SP 6) was used in the regular acupuncture group; based on the treatment of regular acupuncture group, the warming-promotion acupuncture was applied in the warming-promotion acupuncture group, once a day. Ten days were taken as one course with an interval of two days between two courses. Totally 3 treatment courses were completed. The Hamilton depression (HAMD) scale before and after treatment in each group was observed while the efficacy was analyzed.
RESULTSAll three treatments were effective for depression. The total cured rate was 86.67% (26/30) in the warming-promotion acupuncture group, which was obviously superior to 50.00% (15/30) in the regular acupuncture group (P < 0.01) and 33.33% (10/30) in the care group (P < 0.001). After the treatment, the score of HAMD was all reduced in three groups, in which the effect in warming-promotion acupuncture group was superior to that in the regular acupuncture group and care group (9.02 +/- 2.37 vs 10.73 +/- 2.28 and 11.05 +/- 2.01, P < 0.05, P < 0.01).
CONCLUSIONThe warming-promotion acupuncture has positive effect on post-earthquake depression, which has special effect and is worthy of clinical generalization and application.

To investigate the RNA interference (RNAi) effect induced by vector-derived small interfering RNA (siRNA) targeting the three gatekeeper genes (Rad52, Ku70, Ku80) and screen the more effective target sites from candidates for further research, by using siRNA design tools online, we selected 2 candidate sequences directed to every gatekeeper gene. According to the sequences, six vector-derived siRNAs (denoted psiRNA1-6) and one mocking psiRNA7 were constructed. Among them, psiRNA1 and psiRNA2 targeted Rad52, psiRNA3 and psiRNA4 to Ku70, psiRNA5 and psiRNA6 to Ku80. The mocking psiRNA7 was used as control. After sequence identification, the seven plasmids were transfected into HepG2 cell line. siRNA-induced silencing of gatekeeper genes was determined by using RT-PCR at RNA level and Western Blot at protein level. The results showed that the six plasmids specifically targeting the coding region of gatekeeper genes were successfully designed and constructed. To some extent, the six plasmids could reduce the expression of target gene. Comparatively, the plasmid-derived siRNA psiRNA1, psiRNA4 and psiRNA5 were more effective than their counterparts. The results suggest that the gene silencing efficiency of siRNA is different, depending on their targeted region, and siRNA may provide us with practical tools for further study on the three gatekeeper genes, i.e. Rad52, Ku70, Ku80.

The epidemic of COVID-19 has brought great challenges to the global public health prevention and control system combined with clinical diagnosis and treatment system, and it makes the development of effective antiviral drugs an important task in current pharmaceutical research. Traditional Chinese medicine (TCM) has played an important role in the prevention and control of COVID-19. Due to its numerous chemical components and various structural types, TCM becomes a natural library for searching for lead compounds against SARS-CoV-2. In this study, a novel dual-target surface plasmon resonance (SPR) biosensor was developed for S protein receptor binding domain (SRBD) and angiotensin converting enzyme 2 (ACE2) which are two key proteins in the process of SARS-CoV-2 invading cells according to characteristics of synergistic effects of multiple components and comprehensive regulation of multiple targets of TCM. The SPR biosensor was applied to screen and identify active components from six TCMs, and daidzin from Puerariae Lobatae Radix was identified to bind with SRBD and ACE2. The affinity constant (

Armillariella tabescens EJLY2098 was induced to produce ?-mannanase with konjac fine flour (Amorphopallus rivieri) as single carbon source. This induced enzyme was then purified using DEAE ion exchange chromatography and named atMAN47. Zymologic analysis showed that the molecular weight of this ?-mannanase was approximately 47 kD. The enzyme was stable when pH ranged from 5.0 to 6.5 and could be activated by Na+ and Ba2+. With an optimal temperature of 50?C. Action mode analysis of TLC revealed that the enzyme belonged to the endo-?-mannanase family. Being a meta-acid endo-?-mannanase, it was suitable to be applied to feed industry with a promising future as an enzyme preparation.

Objective:To investigate the effect of staphylococcus aureus on expressions of inducible nitric oxide synthase (iNOS) and interleukin-1 beta (IL-1β) in THP-1 monocytes under high glucose concentrations. Methods:THP- 1 monocytes were incubated at different surroundings with 2×2 factorial design. There were 4 experimental groups in the study, which were analyzed by univariate analysis of variance. The total RNA was distilled. The expressions of iNOS and IL-1β were examined by SQ-RT-PCR. Results:The expressions of iNOS and IL-1β were affected by high glucose concentration, bacteria and both of them together in THP-1 monocytes. The expressions of iNOS and IL-1β were weakened in high glucose concentration compared with that of control(P < 0.01). The expressions of iNOS and IL-1β were weakened in the high glucose concentration and bacterial infection compared with that of the high glucose concentration only(P < 0.01). The expressions of iNOS and IL-1β increased in bacterial infection compared with that of control(P < 0.01). The expression of IL-1β increased in high glucose concentration and bacterial infection compared with that of the high glucose concentration only(P < 0.01) but the expression of iNOS was not distinct. Conclusion:When staphylococcus aureus infected monocytes, the expressions of iNOS and IL-1β were weakened in high glucose concentration, which suggested that the depressed function of immunocyte was related with high glucose concentration.
