ObjectiveTo establish the specific chromatogram and quantitative analysis of multi-components by single-marker（QAMS） based on linear calibration using two reference substances（LCTRS）， explore the consistency between Hedyotis Herba dispensing granules and standard decoction， and evaluate the quality of the dispensing granules. MethodsHigh performance liquid chromatography（HPLC） specific chromatogram was established based on 15 batches of Hedyotis Herba standard decoction and 10 batches of the dispensing granules， and LCTRS was used to locate chromatographic peaks. The actual retention times of 7 characteristic peaks in the specific chromatogram was measured on 24 different types of C₁₈ columns， taking deacetyl asperulosidic acid and asperulosidic acid as the dual standard compounds， the retention times of the other 5 characteristic peaks were predicted and validated. Based on this， QAMS was developed to determine the contents of four components（deacetyl asperulosidic acid， deacetyl asperulosidic acid methyl ester， asperulosidic acid， and p-coumaric acid）. Then， the relative correction factors of deacetyl asperulosidic acid， deacetyl asperulosidic acid methyl ester and p-coumaric acid were calculated using the reference peak of asperulosidic acid in the dual standard compounds， and each component was quantified accordingly. Finally， the consistency between the dispensing granules and standard decoction was assessed by taking extract rate of the standard decoction， consistency of the specific chromatograms， contents and transfer rates of the indicator components as indexes， and the quality of the dispensing granules was evaluated. ResultsThere were 7 common peaks in the characteristic chromatogram of samples of Hedyotis Herba standard decoction and the dispensing granules， and four of them were identified by reference standards， namely deacetyl asperulosidic acid（peak 1）， deacetyl asperulosidic acid methyl ester（peak 3）， asperulosidic acid（peak 6） and p-coumaric acid（peak 7）. The similarity between the dispensing granules and the standard decoction was >0.9. The absolute deviation in the predicted retention time for each component by LCTRS was lower than that of the relative retention time method. The extract rate of the 15 batches of Hedyotis Herba standard decoction ranged from 7.89% to 14.60%， the contents of deacetyl asperulosidic acid， deacetyl asperulosidic acid methyl ester， asperulosidic acid and p-coumaric acid were 6.62-19.70， 3.83-17.99， 1.57-6.69， 1.62-4.52 mg·g^-1， and the transfer rates of these components from decoction pieces to the standard decoction were 22.89%-39.60%， 34.03%-62.24%， 24.25%-43.70%， and 40.58%-73.71%， respectively. The extract rate， index component contents and transfer rates from decoction pieces to the three batches of Hedyotis Herba dispensing granules（P1-P3）， produced by manufacturer A， were similar to those of the standard decoction prepared from the same batch of decoction pieces， and all fell within the specified range. The contents of the 4 indicator components in 7 batches of the dispensing granules（P4-P10） from manufacturers B-E were all within the range of the content converted from the standard decoction based on the quantity of the dispensing granules. ConclusionThe established specific chromatogram and QAMS based on LCTRS are reasonable and reliable. Based on the evaluation indicators of standard decoction yield， consistency of specific chromatograms， contents and transfer rates of the four index components， the 10 batches of Hedyotis Herba dispensing granules from various manufacturers have exhibited good consistency with the standard decoction， indicating that the current production process is relatively reasonable.

BACKGROUND: Severe stroke has high rates of mortality and morbidity. This study aimed to investigate the clinical course, causes of worsening, and outcomes of severe ischemic stroke. METHODS: This prospective, multicenter cohort study enrolled adult patients admitted ≤30 days after ischemic stroke from nine hospitals in China between September 2017 and December 2019. Severe stroke was defined as a score of ≥15 on the National Institutes of Health Stroke Scale (NIHSS). Clinical worsening was defined as an increase of 4 in the NIHSS score from baseline. Unfavorable functional outcome was defined as a modified Rankin scale score ≥3 at 3 months and 1 year after stroke onset, respectively. We performed Logistic regression to explore baseline features and reperfusion therapies associated with clinical worsening and functional outcomes. RESULTS: Among 4201 patients enrolled, 854 patients (20.33%) had severe stroke on admission. Of 3347 patients without severe stroke on admission, 142 (4.24%) patients developed severe stroke in hospital. Of 854 patients with severe stroke on admission, 33.95% (290/854) experienced clinical worsening (median time from stroke onset: 43 h, Q1-Q3: 20-88 h), with brain edema (54.83% [159/290]) as the leading cause; 24.59% (210/854) of these patients died by 30 days, and 81.47% (677/831) and 78.44% (633/807) had unfavorable functional outcomes at 3 months and 1 year respectively. Reperfusion reduced the risk of worsening (adjusted odds ratio [OR]: 0.24, 95% confidence interval [CI]: 0.12-0.49, P  <0.01), 30-day death (adjusted OR: 0.22, 95% CI: 0.11-0.41, P  <0.01), and unfavorable functional outcomes at 3 months (adjusted OR: 0.24, 95% CI: 0.08-0.68, P <0.01) and 1 year (adjusted OR: 0.17, 95% CI: 0.06-0.50, P  <0.01). CONCLUSIONS: Approximately one-fifth of patients with ischemic stroke had severe neurological deficits on admission. Clinical worsening mainly occurred in the first 3 to 4 days after stroke onset, with brain edema as the leading cause of worsening. Reperfusion reduced the risk of clinical worsening and improved functional outcomes. REGISTRATION ClinicalTrials.gov , NCT03222024.

BACKGROUND: The effect of the interval between previous Helicobacter pylori (H. pylori) eradication and rescue treatment on therapeutic outcomes remains unknown. The aim of this study was to investigate the association between eradication rates and treatment interval durations in H. pylori infections. METHODS: This prospective observational study was conducted from December 2021 to February 2023 at six tertiary hospitals in Shandong, China. We recruited patients who were positive for H. pylori infection and required rescue treatment. Demographic information, previous times of eradication therapy, last eradication therapy date, and history of antibiotic use data were collected. The patients were divided into four groups based on the rescue treatment interval length: Group A, ≥4 weeks and ≤3 months; Group B, >3 and ≤6 months; Group C, >6 and ≤12 months; and Group D, >12 months. The primary outcome was the eradication rate of H. pylori . Drug compliance and adverse events (AEs) were also assessed. Pearson's χ2 test or Fisher's exact test was used to compare eradication rates between groups. RESULTS: A total of 670 patients were enrolled in this study. The intention-to-treat (ITT) eradication rates were 88.3% (158/179) in Group A, 89.6% (120/134) in Group B, 89.1% (123/138) in Group C, and 87.7% (192/219) in Group D. The per-protocol (PP) eradication rates were 92.9% (156/168) in Group A, 94.5% (120/127) in Group B, 94.5% (121/128) in Group C, and 93.6% (190/203) in Group D. There was no statistically significant difference in the eradication rates between groups in either the ITT ( P = 0.949) or PP analysis ( P = 0.921). No significant differences were observed in the incidence of AEs ( P = 0.934) or drug compliance ( P = 0.849) between groups. CONCLUSION: The interval duration of rescue treatment had no significant effect on H. pylori eradication rates or the incidence of AEs. REGISTRATION ClinicalTrials.gov , NCT05173493.

Objective:To investigate the perinatal risk factors and correlation between bronchopulmonary dysplasia (BPD) and retinopathy of prematurity (ROP).Methods:A retrospective analysis was performed on 173 preterm infants born at less than 32 weeks' gestation with BPD who were admitted to the neonatal intensive care unit (NICU) of the Women and Children's Hospital of Qingdao University from June 2017 to July 2022. According to the diagnostic criteria for ROP, these preterm infants were divided into the ROP group ( n=64) and the non-ROP group ( n=109). Chi-square test, two independent samples t-test, and Mann-Whitney U test were used to compare the general data, treatment, and the incidence of complications between the two groups. Multivariate logistic stepwise regression analysis was used to analyze the independent risk factors of ROP in preterm infants with BPD and the receiver operating characteristic (ROC) curve was drawn to analyze the predictive value of independent risk factors on ROP. The correlation between the severity of BPD and the incidence of ROP was analyzed. Results:The gestational age at birth [(28.0±1.1) vs. (28.8±1.2) weeks, t=4.01], the birth weight [(1 075.9±141.4) vs. (1 143.2±168.6) g, t=2.68], the partial pressure of carbon dioxide [42.5 mmHg (1 mmHg=0.133 kPa) (34.0-51.0 mmHg) vs. 47.0 mmHg (39.0-54.0 mmHg), Z=－2.31], and the total fluid intake on the first day of birth [80.0 ml (72.3-88.7 ml) vs. 83.6 ml (76.6-92.8 ml), Z=－2.28] in the ROP group were all lower than those in the non-ROP group (all P<0.05). While the prothrombin time [15.7 s (14.1-17.7 s) vs. 14.6 s (13.1-16.7 s), Z=－2.17], activated partial thromboplastin time [64.7 s (52.9-77.9 s) vs. 55.8 s (48.4-68.9 s), Z=－2.12], the proportion of patients treated with pulmonary surfactant [71.9% (46/64) vs. 49.5% (54/109), χ 2=8.25], the total duration of oxygen supplementation [50.5 d (40.0-64.0 d) vs. 45.0 d (37.0-52.0 d), Z=－2.77], the duration of invasive ventilation [5.0 d (1.0-11.0 d) vs. 1.0 d (0.0-5.0 d), Z=－4.03], the duration of noninvasive ventilation or high-flow oxygen therapy [(31.7±12.7) vs. (26.4±13.1) d, t=－2.59], and the incidence of neonatal respiratory distress syndrome [76.6% (49/64) vs. 57.8% (63/109), χ 2=6.22] were increased in the ROP group (all P<0.05). There was no significant difference in the proportion of BPD treated with corticosteroids between the ROP and non-ROP groups [60.3% (38/63) vs. 74.3% (81/109), χ 2=3.67, P=0.055]. Multivariate logistic stepwise regression analysis showed that smaller gestational age ( OR=1.599, 95% CI: 1.126-2.272, P=0.009), less fluid intake on the first day ( OR=1.033, 95% CI: 1.004-1.062, P=0.024), and longer duration of invasive ventilation ( OR=1.076, 95% CI:1.017-1.138, P=0.011) were independent risk factors for ROP in BPD infants, while glucocorticoid treatment was an independent protective factor ( OR=0.378, 95% CI:0.173-0.827, P=0.015). Most patients with mild or moderate BPD did not develop ROP [64.6% (73/113) and 66.7% (34/51)], while those with severe BPD were more likely to be complicated by ROP (7/9) ( χ 2=6.84, P=0.033). Conclusions:BPD infants with smaller gestational age, longer duration of invasive ventilation, and less fluid intake on the first day of birth are more likely to develop ROP, while glucocorticoid therapy can reduce the incidence of ROP in this population. Severe BPD may increase the risk of ROP in infants.

Objective:To investigate the prevalence of adult skeletal fluorosis caused by drinking tea-type endemic fluorosis in Yushu Tibetan Autonomous Prefecture (hereinafter referred to as Yushu Prefecture), Qinghai Province, and provide scientific basis for prevention and control of the disease.Methods:In August 2021, one village was selected as a survey site in six counties (cities) in Yushu Prefecture, including Nangqian, Chindu, Yushu, Zadoi, Qumarlêb, and Zhiduo. Drinking water samples and 10 brick tea samples were collected from each village to determine the fluoride content in water and brick tea; at least 100 permanent residents aged ≥ 25, who had a habit of drinking brick tea and had lived in the local area for more than 5 years, were selected for X-ray imaging to examine the prevalence of adult skeletal fluorosis.Results:A total of 75 samples of residential drinking water were collected, with a fluoride content of (0.21 ± 0.05) mg/L, ranging from 0.11 to 0.34 mg/L; 60 samples of brick tea, with a fluoride content of (626.70 ± 157.27) mg/kg, ranging from 324.00 to 2 102.00 mg/kg. A total of 1 136 adults were examined, and 318 cases of skeletal fluorosis were diagnosed, with a detection rate of 27.99%. Among them, the detection rates of mild, moderate, and severe skeletal fluorosis were 20.95% (238/1 136), 6.07% (69/1 136), and 0.97% (11/1 136), respectively, with mild symptoms being the main. The detection rates of skeletal fluorosis in males and females were 29.09% (121/416) and 27.36% (197/720), respectively, with no statistically significant difference between the gender (χ 2 = 0.39, P = 0.533). Comparison of the skeletal fluorosis in different gender, the differences were statistically significant (χ 2 = 22.31, P < 0.001). The detection rates of skeletal fluorosis in the age groups of 25 - 35, 36 - 45, 46 - 55, 56 - 65, 66 - 75, and ≥76 years old were 6.86% (7/102), 22.37% (51/228), 24.02% (92/383), 37.44% (73/195), 43.48% (70/161), and 37.31% (25/67), respectively. The differences between the groups were statistically significant (χ 2 = 59.84, P < 0.001). Moreover, there was a statistically significant difference in the composition of skeletal fluorosis among different age groups ( H = 37.66, P < 0.001). The Spearman correlation analysis results showed that the severity of adult skeletal fluorosis was positively correlated with age ( r = 0.34, P < 0.001). Conclusions:There is a certain degree of prevalence of adult skeletal fluorosis in Yushu Prefecture. And as age increases, the condition of skeletal fluorosis becomes more severe.

Objective To analyze the influence of medication compliance of chronic type 2 diabetes management patients on disease control in two communities in Kunming.Methods A total of 138 patients with type 2 diabetes who were included in chronic disease management in Guandu and Xiaobanqiao communities of Kunming were selected from December 2021 to September 2022.Basic information collection and HbAlc and other related tests were improved.A questionnaire survey of 8-item Morisliy medication adherence scale(MMAS-8)was conducted to analyze the levels of HbAlc and other indexes of three groups with high(group A),medium(group B),and low(group C)adherence,and to conduct statistical analysis.Results Group A accounted for 22.5%,group B for 44.9%,and group C for 32.6%.There were significance differences in urinary albumin creatinine ratio(UACR),HbA1c and blood creatinine among the three groups(P<0.05).The levels of UACR,HbAlc and serum creatinine in group A were lower than those in group B and group C,and there was a negative correlation between UACR,HbAlc and serum creatinine and medication compliance rate(P<0.05).Conclusion In the Guandu Community and Xiaobanqiao community of Kunming,only 22.5%of patients with chronic type 2 diabetes had high medication compliance.The higher the compliance,the lower the level of UACR,HbAlc and serum creatinine,there is a correlation between the two,suggesting that medication compliance should be regarded as one of the key points in the management of chronic diabetes mellitus in the community,and the intervention of patients'medication compliance should be strengthened.

Objective To study the mechanism of the treatment of metabolism associated steatohepatitis(MASH)in rats with Xiaoyao Wan.Methods Twenty-four SD male rats were randomly divided into control group(CON group,n=8)and model group(n=8).The model group was given high-fat diet,carbon tetrachloride(CCl4)subcutaneous injection,hunger and satiety disorder and tail clamping for four weeks to establish the MASH model,and the rats were randomly divided into the MOD group and the Xiaoyao Wan group(XYW group),with 8 rats in each group.The rats of the XYW group were given Xiaoyao Wan,the other two groups were given normal saline.Four weeks after administration,the serum biochemical indexes and oxidative stress indexes of rats in different groups were detected.The pathological sections of rat liver tissue were observed by hematoxylin-eosin(HE)stai-ning and oil red O staining.The expression of cytochrome P450 2E1(CYP2E1),factor-related apoptosis ligand(FasL),tumor necrosis factor-α(TNF-α)and tumor growth factor-β1(TGF-β1)in rat liver were detected by Western blot method.The relative contents of CYP2E1,FasL,TNF-α and TGF-β1 mRNA in liver tissue were de-tected by RT-qPCR.Results The general condition of rats in the XYW group was significantly improved compared with the MOD group;the level of hepatic index was significant decrease compared with the MOD group(P＜0.01)and the level of body mass index was significant increase compared with the MOD group(P＜0.01);the serum levels of triglyceride,total cholesterol,low-density lipoprotein cholesterol,aspartate aminotransferase,alanine aminotransferase,malondialdehyde,monocyte chemotactic protein-1,TNF-α,and interleukin(IL)-18 were signif-icantly reduced compared with the MOD group(all P＜0.05),and the levels of high-density lipoprotein choles-terol,superoxide dismutase,and IL-10 were significantly elevated compared with the MOD group(all P＜0.05);the content of lipid droplets in hepatocytes of rats was significantly reduced compared with the MOD group under light microscope;the protein levels of CYP2E1,FasL,TNF-α and TGF-β1 in liver tissues were significantly re-duced compared with the MOD group(all P＜0.05),and the relative contents of CYP2E1,FasL,TNF-α and TGF-β1 mRNA were significantly reduced compared with the MOD group(all P＜0.05).Conclusion Xiaoyao Wan can regulate the expression of CYP2E1,FasL,TNF-α and TGF-β1 in the liver tissue of MASH rats by reduc-ing the accumulation of fat in the liver,so as to achieve the purpose of treating MASH.

Small cell lung cancer (SCLC) accounts for about 13%~17% of primary bronchial lung cancer. Due to its rapid growth rate, aggressive behavior, early metastasis and poor prognosis, about 70% of patients were diagnosed with extensive-stage (ES) disease. Although most ES-SCLC patients are sensitive to initial chemotherapy, local recurrence and distant metastasis develop in the short term. Immunotherapy has brought the dawn to overcome it. At present, immune checkpoint inhibitor combined with chemotherapy has become an important strategy as first-line therapy for ES-SCLC. Nevertheless, patients are still at a high risk of chest lesion recurrence after initial systemic therapy. Whether the addition of thoracic consolidation radiotherapy (TRT) can reduce chest lesion recurrence rate remains to be determined. In this review, we summarized the latest research progress in the mode of first-line chemotherapy combined with immunotherapy followed by TRT in ES-SCLC, aiming to provide reference for clinical practice.
