OBJECTIVE: To investigate the effectiveness of Xuanshen Yishen Decoction (XYD) in the treatment of hypertension. METHODS: Hospital electronic medical records from 2019-2023 were utilized to emulate a randomized pragmatic clinical trial. Hypertensive participants were eligible if they were aged ⩾40 years with baseline systolic blood pressure (BP) ⩾140 mm Hg. Patients treated with XYD plus antihypertensive regimen were assigned to the treatment group, whereas those who followed only antihypertensive regimen were assigned to the control group. The primary outcome assessed was the attainment rate of intensive BP control at discharge, with the secondary outcome focusing on the 6-month all-cause readmission rate. RESULTS: The study included 3,302 patients, comprising 2,943 individuals in the control group and 359 in the treatment group. Compared with the control group, a higher proportion in the treatment group achieved the target BP for intensive BP control [8.09% vs. 17.5%; odds ratio (OR)=2.29, 95% confidence interval (CI)=1.68 to 3.13; P<0.001], particularly in individuals with high homocysteine levels (OR=3.13; 95% CI=1.72 to 5.71; P<0.001; P for interaction=0.041). Furthermore, the 6-month all-cause readmission rate in the treatment group was lower than in the control group (hazard ratio=0.58; 95% CI=0.36 to 0.91; P=0.019), and the robustness of the results was confirmed by sensitivity analyse. CONCLUSIONS XYD could be a complementary therapy for intensive BP control. Our study offers real-world evidence and guides the choice of complementary and alternative therapies.

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.

COVID-19 pandemic caused by SARS-CoV-2 infection severely threatens global health and economic development. No effective antiviral drug is currently available to treat COVID-19 and any other human coronavirus infections. We report herein that a macrolide antibiotic, carrimycin, potently inhibited the cytopathic effects (CPE) and reduced the levels of viral protein and RNA in multiple cell types infected by human coronavirus 229E, OC43, and SARS-CoV-2. Time-of-addition and pseudotype virus infection studies indicated that carrimycin inhibited one or multiple post-entry replication events of human coronavirus infection. In support of this notion, metabolic labelling studies showed that carrimycin significantly inhibited the synthesis of viral RNA. Our studies thus strongly suggest that carrimycin is an antiviral agent against a broad-spectrum of human coronaviruses and its therapeutic efficacy to COVID-19 is currently under clinical investigation.

Japanese Society for Cancer of the Colon and Rectum (JSCCR) guideline 2019 recommended that lymph node dissection for advanced rectal cancer should include the lymphatic adipose tissue at the root of the inferior mesenteric vessels, but the ligation site of the inferior mesenteric artery (IMA) was not determined, and the NCCN guideline did not indicate clearly whether to retain the left colonic artery (LCA). Controversy over whether to retain LCA is no more than whether it can reduce the incidence of anastomotic complications or postoperative functional damage without affecting the patients' oncological outcome. Focusing on the above problems, this paper reviews the latest research progress. In conclusion, it is believed that the advantages of retaining LCA are supported by most studies, which can improve the blood supply of the proximal anastomosis, and technically can achieve the same range of lymph node dissection as IMA high ligation. However, whether it affects the survival of patients, reduces the incidence of anastomotic leakage, and improves the quality of life of patients, more high-quality evidence-based medical evidence is still needed.

BACKGROUND: Despite the recent advances in treatments for rheumatoid arthritis (RA), there are still unmet needs in disease outcomes. This study aimed to analyze the satisfaction with drug therapies for RA according to the levels of disease severity (patient-assessed) and proportions of treatment cost to household income. METHODS: This was a subgroup study of a cross-sectional study in patients with RA and their physicians. The patients were subdivided into different subgroups based on their self-assessed severity of RA and on the proportions of treatment cost to household income (<10%, 10-30%, 31-50%, and >50%). The Treatment Satisfaction Questionnaire for Medication version II was used to assess patients' treatment satisfaction. RESULTS: When considering all medications, effectiveness, convenience, and global satisfaction scores were lower in the severe and moderate RA subgroups than those in the mild and extremely mild RA subgroups (all P < 0.001). Effectiveness, side effects, and convenience scores were higher in the <10% subgroup compared to those in the >50% subgroup (all P < 0.05). Global satisfaction score was higher in the <10% subgroup than that in the 31% to 50% subgroup (F = 13.183, P = 0.004). For biological disease-modifying anti-rheumatic drugs, effectiveness and convenience scores were lower in the severe RA subgroup than those in the extremely mild RA subgroup (both P < 0.05). Convenience score was higher in the <10% subgroup compared to that in the 31% to 50% and >50% subgroups (F = 12.646, P = 0.005). Global satisfaction score was higher in the <10% subgroup than that in the 31% to 50% subgroup (F = 8.794, P = 0.032). CONCLUSION Higher disease severity and higher financial burden were associated with lower patient satisfaction.

【Objective】To provide a rabbit model for dry eye using a dry environment induced by Controlled Drying System.【Methods】Twenty-four male New Zealand rabbits were used in the experiment. They were randomly divided into control group and dry group，each one with 12 rabbits. The dry group was randomly housed in Controlled Drying System（CDS）for 14 days. The relative humidity，airflow and temperature were kept at（22±4）%，3~4 m/s and（23~25）℃， respectively. The control group were fed in a normal environment where relative humidity，airflow and temperature were kept at 60%~70%，0.2 m/s and（23~25）℃. The Schirmer test，corneal fluorescein staining，conjunctival lissamine green staining were performed during the experimental process on days 0，3，7，and 14. On the last day，the rabbits were euthanized and the eye tissues were made into paraffin-cut sections. After staining，we evaluated the corneal epithelial thickness and goblet cell number in the conjunctiva using light microscopy. MUC5AC in the conjunctival epithelium was detected by immunofluorescence. The apoptosis level changes on the ocular surface were evaluated using Caspase- 3 by immunohistochemistry. 【Results】 Decreased tear production ，increased corneal fluorescein staining and increased conjunctival lissamine green staining were found on days 3，7，and 14 in the dry group compared with the control group（P < 0.001）. Corneal epithelial thickness of control group and dry group were （58.0±7.2）μ m and（47.8±7.6）μ m ，which showed corneal epithelial thickness of dry group was decreased（P＜0.05）. Goblet cells in the conjunctiva of control group and dry group were 15 ± 4 and 10 ± 2，which showed goblet cells of dry group was decreased（P＜0.01）. The expression of MUC5AC（consistent with goblet cells deficiency） was also reduced. Caspase- 3 was highly expressed on the corneal epithelium in the dry group. IOD/field of control group and dry group were（17±2）% and（20±2）%（P＜0.01）.【Conclusions】 Dry environment can make rabbits have pathological changes of dry eye on ocular surface epithelium. This dry eye model of rabbit caused by Controlled Drying System would be an effective tool to study the pathogenesis of dry eye.

This study aimed to establish an animal model of decompression-induced lung injury (DILI) secondary to repetitive diving in mice and explore the role of macrophages in DILI and the protective effects of high-concentration hydrogen (HCH) on DILI. Mice were divided into three groups: control group, DILI group, and HCH group. Mice were exposed to hyperbaric air at 600 kPa for 60 min once daily for consecutive 3 d and then experienced decompression. In HCH group, mice were administered with HCH (66.7% hydrogen and 33.3% oxygen) for 60 min after each hyperbaric exposure. Pulmonary function tests were done 6 h after decompression; the blood was harvested for cell counting; the lung tissues were harvested for the detection of inflammatory cytokines, hematoxylin and eosin (HE) staining, and immunohistochemistry; western blotting and polymerase chain reaction (PCR) were done for the detection of markers for M1 and M2 macrophages. Our results showed that bubbles formed after decompression and repeated hyperbaric exposures significantly reduced the total lung volume and functional residual volume. Moreover, repetitive diving dramatically increased proinflammatory factors and increased the markers of both M1 and M2 macrophages. HCH inhalation improved lung function to a certain extent, and significantly reduced the pro-inflammatory factors. These effects were related to the reduction of M1 macrophages as well as the increase in M2 macrophages. This study indicates that repetitive diving damages lung function and activates lung macrophages, resulting in lung inflammation. HCH inhalation after each diving may be a promising strategy for the prevention of DILI.

Kidney stones are a common urinary system condition that can progress to kidney disease. Previous studies on the association between tea consumption and kidney stones are inconsistent. A cross-sectional study to investigate the association between tea consumption and kidney stones was conducted from 2013 to 2014 and recruited 9,078 northern Chinese adults. A total of 8,807 participants were included in the final analysis. Participants' prevalence of kidney stones was 1.07%, 1.73%, and 2.25% based on their tea consumption frequency of never, occasionally, and often groups, respectively. Compared with the 'never' group, the odds ratios (95% confidence intervals) for the occurrence of kidney stones were 1.57 (1.00-2.46) and 1.65 (1.06-2.57) in the 'occasionally' and 'often' groups, respectively. After adjusting for sex, age, and other potential confounding factors, tea consumption still significantly increased the risk of kidney stones. Tea consumption is independently associated with an increased risk of kidney stones in the investigated population, suggesting that a decrease in the consumption of tea may be a preventive strategy for kidney stones.

OBJECTIVETo investigate the cut-off value in screening of thalassemia in pregnant women from Shenzhen region by capillary hemoglobin electrophoresis.

METHODSThe data of capillary hemoglobin electrophoresis and genetic diagnosis of thalassemia from 2122 examined prenatal women were retrospectively analyzed. Capillary hemoglobin electrophoresis and α-, β- genetic diagnosis of thalassemia were carried out for every woman. Hemoglobin electrophoresis was performed using Capillarys 2 full-automated electrophoresis instrument. Gap polymerase chain reaction and reverse dot blot were used for genetic diagnosis of thalassemia genotyping test. The cut-off value in screening of thalassemia was determined by receiver operating characteristic curve and next to analyze the value of HbA2 and HbF in screening of thalassemia using the decided cut-off value.

RESULTSThe areas under the curve (AUC(Roc)) of HbA2 for diagnosis of α-, β- thalassemia were 0.75 and 0.981 respectively, and the AUC(Roc) of HbF for diagnosis of β-thalassemia was 0.787. When HbA2 ≤ 2.55 was taken as the cut-off value of HbA2 for diagnosis of α-thalassemia, the sensitivity, specificity, positive likelihood ratio (LR(+)) and negative likelihood ratio (LR(-)) were 89.5%, 54.8%, 1.98, 0.19 respectively. When HbA2 ≥3.9 was taken as the cut off value of HbA2 for diagnosis of β-thalassemia, the sensitivity, specificity, LR(+) and LR(-) were 96.1%, 99.8% 480.5, 0.04 respectively. When HbF ≥0.75 was taken as the cut off value of HbF for diagnosis of β-thalassemia, the sensitivity, specificity, LR(+) and LR(-) were 83.6%, 61.8% respectively.

CONCLUSIONThe cut-off value in screening of thalassemia by capillarys 2 full automated electrophoresis instrument is different from that of the traditional method of hemoglobin electrophoresis, such as cellulose acetate membrane electrophoresis and agarose gel electrophoresis. Each laboratory should establish their own respective cut off value.
