OBJECTIVE To explore the pharmacokinetic characteristics of 3 blood-absorbed components of Xiangshao sanjie oral liquid in rats with hyperplasia of mammary gland （HMG）. METHODS Female SD rats were divided into control group and HMG group according to body weight， with 6 rats in each group. The HMG group was given estrogen+progesterone to construct HMG model. After modeling， two groups were given 1.485 g/kg of Xiangshao sanjie oral liquid （calculated by crude drug） intragastrically， once a day， for 7 consecutive days. Blood samples were collected before the first administration （0 h）， and at 5， 15， 30 minutes and 1， 2， 4， 8， 12， 24 hours after the last administration， respectively. Using chlorzoxazone as the internal standard， the plasma concentrations of ferulic acid， paeoniflorin and rosmarinic acid in rats were detected by UPLC-Q/TOF-MS. The pharmacokinetic parameters [area under the drug time curve （AUC0－24 h， AUC0－∞）， mean residence time （MRT0－∞）， half-life （t1/2）， peak time （tmax）， peak concentration （cmax）] were calculated by the non-atrioventricular model using Phoenix WinNonlin 8.1 software. RESULTS Compared with the control group， the AUC0－24 h， AUC0－∞ and cmax of ferulic acid in the HMG group were significantly increased （P＜0.05）； the AUC0－24 h， AUC0－∞ ， MRT0－∞ ， t1/2 and cmax of paeoniflorin increased， but there was no significant difference between 2 groups （P＞0.05）； the AUC0－24 h and MRT0-∞ of rosmarinic acid were significantly increased or prolonged （P＜0.05）. C ONCLUSIONS In HMG model rats， the exposure of ferulic acid， paeoniflorin and rosmarinic acid in Xiangshao sanjie oral liquid all increase， and the retention time of rosmarinic acid is significantly prolonged.

PURPOSE: Traumatic brain injury (TBI) is a significant public health issue that impacts individuals all over the world and is one of the main causes of mortality and morbidity. Decompressive craniectomy is the usual course of treatment. Basal cisternostomy has been shown to be highly effective as an alternative procedure to decompressive craniectomy. METHODS: We conducted a retrospective cohort of patients who received surgery for severe TBI between January 2019 and March 2023. Inclusion criterias were patients between the ages of 18 and 70 years who met the diagnostic criteria for severe TBI at first presentation and who underwent surgical intervention. The exclusion criteria were patients who have severe multiple injuries at the time of admission; preoperative intracranial pressure > 60 mmHg; cognitive impairment before the onset of the disease; hematologic disorders; or impaired functioning of the heart, liver, kidneys, or other visceral organs. Depending on the surgical approach, the patients were categorized into decompressive craniectomy group as well as basal cisternostomy group. General data and postoperative indicators, including Glasgow coma scale, intracranial pressure, etc., were recorded for both groups of patients. Among them, the Glasgow outcome scale extended assessment at 6 months served as the primary outcome. After that, the data were statistically analyzed using SPSS software. RESULTS: The trial enrolled 41 patients (32 men and 9 women) who met the inclusion criteria. Among them, 25 patients received decompressive decompressive craniectomy, and 16 patients received basal cisternostomy. Three days postoperative intracranial pressure levels were 10.07 ± 2.94 mmHg and 17.15 ± 14.65 mmHg (p = 0.013), respectively. The 6 months following discharge Glasgow outcome scale extended of patients was 4.73 ± 2.28 and 3.14 ± 2.15 (p = 0.027), respectively. CONCLUSION Our study reveals that basal cisternostomy in patients with surgically treated severe TBI has demonstrated significant efficacy in reducing intracranial pressure as well as patient prognosis follow-up and avoids removal of the bone flap. The efficacy of cisternostomy has to be studied in larger, multi-clinical center randomized trials.

Objective:To examine the burden and trends of acute viral hepatitis in Guangdong Province from 1990 to 2019, and provide reference evidences for hepatitis prevention and control in the province.Methods:Data on acute viral hepatitis (hepatitis A, B, C, and E) in Guangdong from 1990 to 2019 were extracted from the Global Burden of Disease Study 2019 database. The incidence, prevalence, mortality, and disability-adjusted life years (DALY) data were analyzed by age and gender, and the estimated annual percentage change (EAPC) was calculated to describe the changing trends in disease burden.Results:From 1999 to 2019, the standardized incidence, prevalence, mortality, and DALY of acute viral hepatitis in Guangdong were higher than the national averages. In 2019, 51.43% (2 245 087/4 365 221) of acute viral hepatitis cases in Guangdong Province were mainly attributed to hepatitis B, and 77.18% (106/138) of deaths were due to acute hepatitis B. In different age groups, except for acute hepatitis B, which was more common in adults, the incidence rates of other types of viral hepatitis such as hepatitis A, B, and E showed an overall decreasing trend with age. The mortality rates of different types of acute viral hepatitis, except for the <5 age group, increased with age. The overall incidence and mortality rates of acute viral hepatitis were higher in men than in women.Conclusions:The overall burden of acute viral hepatitis in Guangdong declined in 2019, but remained higher than the national level. Further efforts are needed to strengthen hepatitis prevention and screening in different population in Guangdong Province, especially in children and the elderly.

As color doppler ultrasound listed as the thyroid to regular physical examination project, the positive detection rate of benign and malignant thyroid diseases has increased year by year. The population of patients after thyroid surgery is getting larger and larger, however, the research on how to replace the absent thyroid with exogenous thyroid hormone is not perfect. As the switch of thyroid hormone activation and deactivation, deiodinase plays an important role in maintaining the internal environment of human body. The expression of these enzymes will change with the different needs of each organ in the individual. In the past, many authors have made a detailed description of deiodinase in basic medicine, but the principle of action in clinical aspects is relatively lacking. In this paper, the mechanism of deiodinase was reviewed through literature reading, to explore the basic principle of deiodinase in exogenous thyroid hormone supplementation after thyroid surgery.

Objective We aimed to investigate the mechanism of Tianma(tall gastrodia tuber)-Hongjingtian(rose root)medicinal pair in regulating tumor necrosis factor-α(TNF-α)/nuclear factor-κB(NF-κB)to protect the endothelial cell barrier in mice with hypoperfused-cerebral small vessel disease.Methods Seventy male C57BL/6 mice were assigned to the sham operation group,model group,Tianma-Hongjingtian groupⅠ,Ⅱ,and Ⅲ(the mass ratio of Tianma to Hongjingtian were 1:1,2:1,and 1:2),with 14 mice in each group.A unilateral common carotid artery occlusion mouse model was established.The mice of each group were gavaged once at six hours after the surgery then once every 24 h thereafter.The doses of Tianma-Hongjingtian groupⅠ,Ⅱ,and Ⅲ were 1.30,1.95,and 1.95 g/(kg·d),and the sham operation and model groups were administered with the same volume of saline.Cerebral blood flow detection and behavioral post and sampling were performed on the 3rd day(acute phase)and 7th day(subacute phase)of the experiment.Laser diffuse linear ratio imaging was used to observe changes in cerebral blood flow.A gait analyzer was used to evaluate motor coordination.Hematoxylin-eosin staining combined with light microscopy was used to observe pathological and morphological changes in brain tissue.Western blotting was used to detect the expression level of albumin.Immunofluorescence and Western blotting were used to detect the expression levels of tight junction proteins(Occludin and ZO-1).The expression levels of TNF-α,NF-κB,IL-β,and IL-6 were detected through RT-PCR and Western blotting.Results Compared with the sham operation group,cerebral blood flow was reduced on the 3rd day and 7th day in the model group(P<0.05);gait abnormalities of prolonged swing duration,reduced stride frequency,and reduced gait equilibrium(P<0.05)were observed;severe pathological damage was observed in brain tissues,with increased level of albumin expression,decreased protein expression levels of Occludin and ZO-1(P<0.05);mRNA and protein expression levels of TNF-α,NF-κB,IL-β,and IL-6 increased(P<0.05).Compared with the model group,the cerebral blood flow of mice on the 3rd and 7th day in the three Tianma-Hongjingtian groups was elevated(P<0.05);swinging duration was shortened,step frequency increased,gait equilibrium was elevated(P<0.05);brain histopathological damage was reduced,albumin expression level decreased(P<0.05),and the expression levels of Occludin and ZO-1 proteins were elevated(P<0.05);the mRNA and protein expression levels of TNF-α,NF-κB,IL-β,and IL-6 were decreased(P<0.05).Among them,the combined efficacy was better on the 3rd day of Tianma-Hongjingtian group Ⅱ;the combined efficacy was better on the 7th day of Tianma-Hongjingtian groupⅢ.Conclusion Tianma-Hongjingtian can increase cerebral blood flow,improve gait abnormalities,reduce pathological damage to brain tissue,and protecte the function and structure of the endothelial barrier in mice with hypoperfused cerebral small vessel disease,and the mechanism may be related to decreasing the expression of inflammatory factors.

Purpose: This study was to investigate the work experience of newly recruited male nurses during the COVID-19 pandemic. Methods: With a phenomenological approach, this qualitative study was adopted semistructured interviews by phone or video calls. A total of 9 male nurses newly recruited for the COVID-19 wards in Chinese hospitals were interviewed for this study. And Colaizzi's method was applied for evaluation in the data analysis. Results: Based on our findings, three themes were extracted. First, the newly recruited male nurses showed negative emotions at the beginning of COVID-19 epidemic, which was caused by changes in working conditions and content, but also prompted the nurses to change the way of coping with the crisis. Second, they gradually mastered the working skills and psychological training to cope with COVID-19 and developed a positive attitude toward life and a high sense of professional responsibility. Finally, we learned about their needs to respond to public health emergencies such as the COVID-19 pandemic. Conclusion COVID-19 is a disaster for all of humanity. The newly recruited male nurses are an important force in emergency rescue. Although they suffered from short-term negative emotions, they quickly adapted to the crisis. In order to better prepare for future emergencies, the disaster response capacity of newly recruited male nurses needs to be further improved. In addition, newly recruited male nurses have a strong demand for timely and personalized career development guidance.

Objective:To clarify the anatomical characteristics and adjacent relationship of the superior segment of the inferior vena cava during laparoscopic surgery.Methods:In December 2018, two frozen and two fresh adult cadavers were dissected. The chest of the frozen cadavers was opened along the bilateral midline of the clavicle, the anterior pericardial wall was opened, and the superior vena cava and the inferior vena cava was dissected. The abdominal cavity was opened along the midline of the abdomen, the left and right hepatic lobes were turned over, the inferior vena cava and the second hilum of the posterior segment of the liver were exposed, and the hiatus of the inferior vena cava was opened and entered the pericardium.The anatomical characteristics and adjacent relationship of the superior segment of the inferior vena cava were observed, and the length of the superior segment of the inferior vena cava was measured. The fresh frozen cadaver patients underwent laparoscopic surgery.Five 12 mm trocars were placed at the side of umbilicus, right rectus abdominis about 4 cm from umbilicus, midline of abdomen about 6 cm above umbilicus, right axillary front about 2 cm below inferior edge of liver, left midline of clavicle about 2 cm below inferior edge of liver. Laparoscopic-assisted turning of the left and right hepatic lobes, exposing the posterior inferior vena cava and the second hilum of the liver, opening of the vena cava hiatus into the pericardium.The anatomical characteristics and adjacent relationship of the upper diaphragmatic segment of the inferior vena cava were observed.Results:In two autopsies, the inferior vena cava entered the chest through the cava sulcus of the liver and the phrenic foramen cava, and then through the fibrous pericardium into the right atrium. The length from the diaphragm of inferior vena cava to the right atrium was 1.67 cm, 2.57 cm. In laparoscopic operation, the diaphragm entrance of the posterior segment of the liver inferior vena cava, the second hepatic portal and the inferior vena cava could be well exposed.The diaphragm could be opened along the hole of the vena cava with a relatively non vascular anatomical layer of adipose tissue.There was a large anatomical gap between the pericardium and the right atrium, and the inferior vena cava, the superior vena cava and the right atrium could be well exposed, and the whole diaphragm could be completely and continuously exposed from the bottom to the inferior vena cava at the entrance segment of the right atrium.Conclusions:There was a relatively avascular anatomical layer beside the inferior vena cava. During laparoscopic operation, opening the diaphragm through the abdominal cavity could safely enter the pericardium and expose the inferior vena cava, the superior vena cava and the right atrium, which provides a possibility for the removal of Mayo Ⅳ grade inferior vena cava tumor thrombus through this approach.
