The statement"Blood is the material carrier of spirit and qi"indicates that the generation of blood relies on the coordinated governance of spirit and qi,while simultaneously serving as their material foundation.Based on the physiological connection among"blood-spirit-qi",this article explores the pathogenesis of premature ovarian insufficiency(POI)accompanied by anxiety and depression.It proposes that essence and blood deficiency,premature exhaustion of Tian Gui(reproductive essence),and failure of blood to nourish the spirit form a pathological chain:"blood deficiency-spirit disturbance-POI with anxiety and depression".Blood stasis obstructing the uterine chamber,disorder of the chong and ren meridians,and failure of blood to carry the spirit give rise to the transformation:"blood stasis-spirit depression-POI with anxiety and depression".Liver qi stagnation and disruption of qi and blood further exacerbate the imbalance between blood and spirit,aggravating the disease progression.Based on this pathological analysis,the general treatment principle of"regulating blood,harmonizing spirit,and rectifying qi"is established.For patients with blood deficiency syndrome,treatment should focus on tonifying essence and blood,replenishing reproductive essence,and nourishing the spirit,selecting Guanyuan(CV4),Zusanli(ST36),and Sanyinjiao(SP6)as main acupoints.For patients with blood stasis syndrome,treatment should aim to regulate the chong and ren meridians,promote blood circulation,and calm the spirit,selecting Qichong(ST30),Zhongji(CV3),and Xuehai(SP10)as main acupoints.Simultaneously,the method of regulating the liver should be applied throughout the entire treatment process to soothe the liver,regulate qi,relieve depression,and calm the spirit,selecting Baihui(GV20),Taichong(LR3),and Ganshu(BL18)as main acupoints.Appropriate acupuncture techniques and methods should be chosen according to the patient's constitution and condition,providing new therapeutic ideas and approaches for clinical practice.

Objective The aim of this study is to evaluate the effect of the payment reform of basic medical insurance on cost,medical behavior and patients′ burden.So as to provide a reference for improving the payment reform in Changsha.Methods Interrupted time-series method was used to analyze the changes of the same-day readmission rate,average hospitalization cost per time and the out-of-pocket proportion before and after the payment reform.Stakeholder interviews were used to investigate suggestions and possible reasons for the change.Results The average hospitalization cost per time and the out-of-pocket proportion of insured patients decreased significantly in early stage of the reform,and then showed an increasing trend.The growth rate of the total number of inpatients and the decrease of same-day readmission rate declined.The results of interrupted time-series analysis showed that the growth rate of total inpatients decreased from 600 per month to 20 per month after the payment reform.The same-day readmission rate increased by 0.237%in the short term after the reform,but showed a downward trend in the long term,with the rate decreasing from 0.014%per month before the reform to 0.003%per month.In the short term after the reform,the average hospitalization cost per time fell by 786.360,and the proportion of out-of-pocket decreased by 2.089%.Conclusion The effects of controlling cost and alleviating patients′ burden were obvious in the initial reform of the basic medical insurance for urban employees in Changsha,but the long-term supervision needs to be strengthened,especially for decomposition of hospitalization and patients′burden relief.

Objective:To investigate the survival of 2019 novel coronavirus (2019-nCoV) on the surface of inanimate objects at different temperatures.Methods:CNKI, WanFang Database, VIP, PubMed, Web of Science, Cochrane Library and Embase were searched for articles published from January 1, 2020 to June 15, 2022 with "2019-nCoV, surface, inanimate, environments, environmental, matrices, factors, conditions, contact, personal protective equipment, transmission, stability, persistence, viability, survival, survivability, infectivity, transmission". The literature was screened according to the inclusion and exclusion criteria. After the data in the literature were extracted, the improved MINORS scale was used to evaluate the literature quality. RevMan5.4 software was used for meta analysis, and Stata17.0 software was used for Begg′s test and Egger′s test to evaluate the publication bias.Results:A total of 20 studies were included. Meta-analysis result showed that the survival ability of 2019-nCoV on the surface of non-porous objects (stainless steel, glass and plastic) was significantly different from that on the surface of porous objects (cloth, wood board, banknote, cotton, cardboard) ( Z=5.94, P<0.001; Z=17.85, P=0.004; Z=38.20, P<0.001). The result of subgroup analysis showed that there was no significant difference in the survival ability of the virus between banknotes and glass, plastic surfaces under the same conditions ( Z=0.81, P=0.420; Z=1.79, P=0.070). The half-life of the virus at 4 ℃ was significantly different from that at 25 ℃[ MD=47.49 h, 95% CI: 7.00~87.99, Z=2.30, P=0.020]; The half-life of the virus at 25 ℃ was also significantly different compared with that at 35 ℃[ MD=5.46 h, 95% CI: 0.13~10.78, Z=2.01, P=0.040]. Conclusions:Under the same conditions, the survival time of 2019-nCoV on the surface of nonporous objects was longer than that on the surface of porous objects, and the higher the temperature, the shorter the survival time.

Objective:To systematically evaluate the clinical efficacy and adverse effects of Janus kinase (JAK) inhibitors in the treatment of Coronavirus Disease 2019 (COVID-19).Methods:Meta-analysis of the clinical efficacy and adverse effects of Janus kinase inhibitors in the treatment of COVID-19 was performed on 19 papers that met the inclusion criteria, including tests for heterogeneity, relative risk ( RR), mean difference( MD) and publication bias. Results:For the Janus kinase inhibitor group compared with the control group in 19 studies, RR and 95% confidence interval (95% CI) were 0.52 (95% CI: 0.44-0.62), 0.45 (95% CI: 0.25-0.83), and 1.21 (95% CI: 1.03-1.43) for mortality, clinical deterioration and recovery rates, and the mean difference and 95% CI in recovery time was -0.96 (95% CI: -1.13--0.79); for adverse events (including serious adverse events, infections, embolism, deep vein thrombosis, pulmonary embolism, liver dysfunction, psychiatric disorders, renal and urinary disorders), only the P-value for serious adverse events was statistically significant, P=0.010, and the RR and 95% CI were 0.83 (95% CI: 0.72-0.97). Conclusions:JAK inhibitors help reduce mortality and improve clinical outcomes in patients hospitalized with COVID-19 without increasing the risk of adverse events.

Nasopharyngeal carcinoma (NPC) is a malignant tumor that mainly occurs in East and Southeast Asia. Although patients benefit from the main NPC treatments (e.g., radiotherapy and concurrent chemotherapy), persistent and recurrent diseases still occur in some NPC patients. Therefore, investigating the pathogenesis of NPC is of great clinical significance. In the present study, replication factor c subunit 4 (RFC4) is a key potential target involved in NPC progression via bioinformatics analysis. Furthermore, the expression and mechanism of RFC4 in NPC were investigated in vitro and in vivo. Our results revealed that RFC4 was more elevated in NPC tumor tissues than in normal tissues. RFC4 knockdown induced G2/M cell cycle arrest and inhibited NPC cell proliferation in vitro and in vivo. Interestingly, HOXA10 was confirmed as a downstream target of RFC4, and the overexpression of HOXA10 attenuated the silencing of RFC4-induced cell proliferation, colony formation inhibition, and cell cycle arrest. For the first time, this study reveals that RFC4 is required for NPC cell proliferation and may play a pivotal role in NPC tumorigenesis.
