Qingzao Jiufeitang is a famous classical formula for treating lung injury caused by warm and dryness， included in the Catalogue of Ancient Famous Classical Formulas（The First Batch）. By systematically organizing ancient and modern literature on this formula， this study analyzed and verified the origin， medicinal composition， original plants and processing， dosage and decoction method， efficacy and application of this formula. According to the research， Qingzao Jiufeitang was first recorded in Yimen Falyu in the Qing dynasty， and its creation was mainly inspired by the Ming dynasty physician MIAO Xiyong's idea of the moisturizing drugs with sweet flavour and cold nature. Based on the 2020 edition of the Pharmacopoeia of the People's Republic of China（hereinafter referred to as the Chinese Pharmacopoeia） and the textual research results of modern scholars on traditional Chinese herbal medicines， the botanical sources and processing methods of the herbs in this formula are basically clarified. Among them， Mori Folium， Gypsum Fibrosum， Ginseng Radix et Rhizoma， Sesami Semen Nigrum， Asini Corii Colla， Ophiopogonis Radix and Eriobotryae Folium are consistent with the 2020 edition of the Chinese Pharmacopoeia. The primary source of Glycyrrhizae Radix et Rhizoma is the dried roots and rhizomes of Glycyrrhiza uralensis， family Leguminosae， while the primary source of Armeniacae Semen Amarum is the dried mature seeds of Prunus armeniaca， family Rosaceae. It is recommended to use Gypsum Ustum， stir-fried Sesami Semen Nigrum， stir-fried Armeniacae Semen Amarum， Asini Corii Colla bead， and honey-fried Eriobotryae Folium， and the rest of the raw products. According to the conversion of ancient and modern doses， the recommended dosages are 11.19 g for Mori Folium， 9.33 g for Gypsum Fibrosum， 3.73 g for Glycyrrhizae Radix et Rhizoma， 2.61 g for Ginseng Radix et Rhizoma， 3.73 g for Sesami Semen Nigrum， 4.48 g for Ophiopogonis Radix， 2.61 g for Armeniacae Semen Amarum， 3.73 g for Eriobotryae Folium. The decoction method is to add 300 mL of water， decoct it down to 180 mL， remove the residue， and then add 2.98 g of Asini Corii Colla into the decoction. Take it warm after meals， two to three times a day. Qingzao Jiufeitang has the effects of clearing dryness and moistening the lungs， nourishing Yin and invigorating Qi. In ancient times， it was mainly used to treat stagnation and depression of various Qi， as well as paralysis， asthma and vomiting. In modern clinical practice， it is mostly used to treat diseases in respiratory system， otolaryngology， skin system and digestive system caused by warm-dry impairing lung， deficiency of both Qi and Yin. The above research results can provide a reference for the later development of Qingzao Jiufeitang.

OBJECTIVE: To investigate the effectiveness of endoscopic-assisted median nerve decompression with one-stage extensor indicis proprius (EIP) tendon transfer for reconstruction of thumb abduction in patients with severe carpal tunnel syndrome (CTS). METHODS: The clinical data of 12 patients with severe CTS who met the selection criteria between December 2019 and December 2024 were retrospectively analyzed. There were 2 males and 10 females with an average age of 55.4 years ranging from 35 to 67 years. The symptom duration of CTS was 12-120 months (mean, 48.7 months) and the thenar muscle atrophy duration was 6-48 months (mean, 13.4 months). The median nerve was released with the help of endoscope, and the EIP tendon was transferred to reconstruct the abduction function of the thumb. The operation time and complications were recorded. Two-point discrimination, palmar abduction angle of the thumb, radial abduction angle of the thumb, and pinch force of the thumb were measured and compared before operation and at last follow-up, and the effectiveness was evaluated by Kapandji score and Disabilities of the Arm, Shoulder and Hand (DASH) score. The satisfaction of the operation was evaluated at last follow-up. RESULTS: All surgeries were successfully completed with a mean operation time of 54 minutes (range, 45-68 minutes). All patients were followed up 6-50 months, with an average of 15.3 months. There was no complications such as wound infection, scar pain of wrist, or tendon rupture of transposition, and there were 3 cases of mild limitation of finger extension in the donor site of index finger. At last follow-up, two-point discrimination, palmar abduction angle of the thumb, radial abduction angle of the thumb, Kapandji score, and DASH score were significantly better than those before operation ( P<0.05), but there was no significant difference in thumb pinch force between pre- and post-operation ( P>0.05). The evaluation of surgical satisfaction showed that 7 cases were very satisfied and 5 cases were satisfied. CONCLUSION The combination of endoscopic-assisted median nerve decompression and one-stage EIP tendon transfer effectively improves hand function and quality of life in patients with severe CTS by restoring thumb abduction and alleviating neurological symptoms.

Consecutively hospitalized patients with confirmed coronavirus disease 2019 (COVID-19) in Wuhan, China were retrospectively enrolled from January 2020 to March 2020 to investigate the association between the use of renin-angiotensin system inhibitor (RAS-I) and the outcome of this disease. Associations between the use of RAS-I (angiotensin-converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB)), ACEI, and ARB and in-hospital mortality were analyzed using multivariate Cox proportional hazards regression models in overall and subgroup of hypertension status. A total of 2771 patients with COVID-19 were included, with moderate and severe cases accounting for 45.0% and 36.5%, respectively. A total of 195 (7.0%) patients died. RAS-I (hazard ratio (HR)= 0.499, 95% confidence interval (CI) 0.325-0.767) and ARB (HR = 0.410, 95% CI 0.240-0.700) use was associated with a reduced risk of all-cause mortality among patients with COVID-19. For patients with hypertension, RAS-I and ARB applications were also associated with a reduced risk of mortality with HR of 0.352 (95% CI 0.162-0.764) and 0.279 (95% CI 0.115-0.677), respectively. RAS-I exhibited protective effects on the survival outcome of COVID-19. ARB use was associated with a reduced risk of all-cause mortality among patients with COVID-19.

Objective:To investigate the prevalence and risk factors of diabetic retinopathy (DR) in patients in Tibet.Methods:A total of 239 patients with DR who received treatment in Department of Endocrinology and Metabolism, Hospital of Chengdu Office of People's Government of Tibet Autonomous Region from December 2017 to December 2018 were included in this study. They were divided into Han nationality and Zang nationality groups according to ethnicity. The condition of DR was evaluated with nonmydriatic ocular fundus photography according to the staging criteria of the severity of retinopathy.Results:The prevalence of DR in Tibet was 18.0％. The prevalence of DR in Tibetan and Han patients with diabetes was 17.5% and 19.2%, respectively. There was no significant difference in the prevalence of DR between Tibetan and Han patients with diabetes ( χ2 = 0.10, P = 0.754). Logistic regression analysis revealed that the risk factors of developing DR in Tibet included diabetes duration ( OR = 1.14, 95% CI: 1.05-1.24, P < 0.05), insulin therapy ( OR = 2.74, 95% CI: 1.09-6.89, P < 0.05), fasting plasma glucose ( OR = 1.37, 95% CI: 1.07-1.75, P < 0.05) and hypertension ( OR = 1.98, 95% CI: 1.02-3.86, P < 0.05). Diabetes duration and fasting plasma glucose are independent risk factors of DR. However, although elevated glycated hemoglobin levels were high in Tibet, they could not be used to predict the risk for developing DR ( OR = 1.01, 95% CI: 0.82-1.25, P > 0.05). Conclusion:Hyperglycemia is an important risk factor of developing DR in Tibet. However, elevated glycated hemoglobin levels cannot be used to predict the risk of developing DR in Tibet. Findings from this study fill the gap in the research on DR prevalence and ethic difference of DR prevalence, providing scientific evidence for prevention and treatment of DR in high-altitude areas.

Objective : To investigate the influence and molecular mechanism of hypoxia-inducing factor-1 α( HIF- 1 α) gene silencing combined with methyl selenenic acid (MSA) on cervical cancer cell proliferation，apoptosis and cell migration． Methods : HeLa cells were transfected with HIF-1 interference RNA and negative control RNA．Af- ter transfection for 48 h，cells were stimulated with MSA for 24 h，and cell proliferation was determined by CCK-8 assay and colony formation．Apoptosis was determined by flow cytometry combined with Annexin V-FITC / PI．The expression levels of HIF-1α , Bcl-2 ，and E-cadherin were detected by Western blot assay． Cell migration ability was determined by Transwell assay. RNA-seq analysis was used to investigate the differentially expressed genes and differential signaling pathways. Results : Compared with the control group，interfering with HIF-1α combined with MSA significantly inhibited cell proliferation (P ＜0．01) ．Flow cytometry results showed that the combined drug group significantly induced apoptosis．Transwell results showed that interfering with HIF-1α combined with MSA inhibited HeLa cell migration．Compared with the control group，interfering with HIF-1α combined with MSA down- regulated the expression of Bcl-2 and up-regulated the expression of E-cadherin. RNA-sequencing combined with signal pathway enrichment results showed that the expression of apoptotic signal pathway and downstream genes was inhibited． Conclusion HIF-1α gene silencing combined with MSA can synergically inhibit the proliferation and induce apoptosis of cervical cancer cells，and its regulatory mechanism may be related to the expression of Bcl-2 family proteins and the inhibition of p53 signaling pathway.

Objective:To investigate the possible role of long non-coding RNA (LncRNA) 00602 in promoting browning in adipocytes induced by adenovirus type 36 (Ad36).Methods:According to Ad36 infection, adipose tissue samples of obese patients were divided into Ad36-negative group and Ad36-infected group. Realtime fluorescent quantitative PCR (qRT-PCR) was used to detect the changes in the expression of LncRNA00602 mRNA in omental adipose tissue of the two groups, and analyze the differences between the two groups. The correlation between waist-to-hip ratio, systolic blood pressure, diastolic blood pressure, fasting blood glucose, triacylglyceride and other indicators of the patients in the group with LncRNA00602 mRNA expression were analyzed. HE staining was used to detect the size of adipocytes in the omental adipose tissue of the Ad36 negative group and the Ad36 infection group. qRT-PCR and Western blotting were used to detect the mRNA and protein expression levels of uncoupling protein 1 (UCP1) and PR domain containing 16 (PRDM16) in omental adipose tissue of two groups of patients. Human adipose-derived stem cells (hADSC) were isolated and cultured, using Ad36 to induce differentiation, and divided into control group and LncRNA00602 knockdown group. On 0, 2, and 4 days after LncRNA00602 knockdown, fluoroboron dipyrrole (BODIPY) and mitochondrial red fluorescence (Mito-Tracker Red) were used to stain intracellular lipid droplets and mitochondria. At the same time, qRT-PCR and Western blotting were used to detect changes in the expression of UCP1 and PRDM16.Results:The expression of LncRNA00602 gene in the Ad36 infection group was higher than that in the Ad36 negative group (all P<0.05). The expression of LncRNA00602 in the Ad36 negative group was not significantly different from the above clinical indicators, while the expression of LncRNA00602 was negatively correlated with serum fasting blood glucose and triacylglyceride ( r=-0.522, -0.486, P<0.05) in the Ad36 infection group; HE staining showed that the average adipocyte area of the Ad36 infection group was smaller than that of the Ad36 negative group. At the same time, UCP1 and PRDM16 gene expression were higher than the negative group (all P<0.05). At the cellular level, on the 2nd and 4th days after knockdown of LncRNA00602, the lipid droplet area of adipocytes in the LncRNA00602 knockdown group was larger than that of the control group, the number of mitochondria decreased compared with the control group, and difference was statistically significant ( P<0.05 or P<0.01); Compared with the control group, there was significantly lower expression of the browning marker genes UCP1, PRDM16, and protein in the adipocytes in the LncRNA00602 knockdown group (all P<0.05). Conclusion:In Ad36-induced adipocyte differentiation, LncRNA00602 may positively regulate the expression of UCP1, PRDM16 and lipid droplet metabolism, and promote the browning of adipocytes.

BACKGROUND: Microglia plays an indispensable role in the pathological process of sleep deprivation (SD). Here, the potential role of microglial CX3C-chemokine receptor 1 (CX3CR1) in modulating the cognition decline during SD was evaluated in terms of microglial neuroinflammation and synaptic pruning. In this study, we aimed to investigat whether the interference in the microglial function by the CX3CR1 knockout affects the CNS's response to SD. METHODS: Middle-aged wild-type (WT) C57BL/6 and CX3CR1-/- mice were either subjected to SD or allowed normal sleep (S) for 8 h to mimic the pathophysiological changes of middle-aged people after staying up all night. After which, behavioral and histological tests were used to explore their different changes. RESULTS: CX3CR1 deficiency prevented SD-induced cognitive impairments, unlike WT groups. Compared with the CX3CR1-/- S group, the CX3CR1-/- SD mice reported a markedly decreased microglia and cellular oncogene fos density in the dentate gyrus (DG), decreased expression of pro-inflammatory cytokines, and decreased microglial phagocytosis-related factors, whereas increased levels of anti-inflammatory cytokines in the hippocampus and a significant increase in the density of spines of the DG were also noted. CONCLUSIONS These findings suggest that CX3CR1 deficiency leads to different cerebral behaviors and responses to SD. The inflammation-attenuating activity and the related modification of synaptic pruning are possible mechanism candidates, which indicate CX3CR1 as a candidate therapeutic target for the prevention of the sleep loss-induced cognitive impairments.

Objective: To analyze the biological effects of miRNA-155 in the cardiac myocyte apoptosis. Methods: The mouse-derived macrophage cell line RAW264.7 was treated by different concentration or different stage of oxidized low density lipoprotein (ox-LDL), and transfected by miR-155 mimic (M group), miR-155 mimics-NC (M-NC group), miR-155 inhibitor (I group) or miR-155 inhibitor-NC (I-NC group), respectively. The cell viability was measured by CCK-8 assay, cell apopotosis was measured by TUNEL and flow cytometry. Results: The ox-LDL induced cell viability of Raw264.7 cells decreased and the expression of miR-155 increased in dose and time dependent manner, after treatment with different concentration of ox-LDL (10, 20, 40, 80, 160 mg/L) or 80 mg/L of ox-LDL with different stage (6, 12, 24, 48, 72 h). The expression of miR-155 increased significantly. Raw264.7 cell viability decreased significantly, compared to that of the blank control. The difference between two groups had statistical significance (P<0.05). The cell viability in M group was significantly higher than that in M-NC group, in I group was significantly higher than that in I-NC group, and the difference between two groups was statistical significance (P<0.05). Compared to that in the M-NC group, the cell apoptosis rate in M group was significantly increased (P<0.05), compared to that in the I-NC group, the cell apoptosis rate in I group were significantly decreased (P<0.05). Conclusions miR-155 can enhance the Raw264.7 cell apoptosis induced by ox-LDL.
