AIM To evaluate the chemical constituent consistency in formula granules and traditional decoctions of Gouteng Jiangya Formula.METHODS HPLC characteristic chromatograms were established,the analysis was performed on a 30 ℃ thermostatic YMC-Triart C18 column(4.6 mm× 250 mm,5 μm),with the mobile phase comprising of acetonitrile-0.2％phosphoric acid flowing at 1.0 mL/min in a gradient elution manner,and the detection wavelength was set at 240 nm.Puerarin was used as an internal standard to calculate the relative correction factors of 3'-methoxy puerarin,puerarin apioside,magnolflorine,paeoniflora,daidzin,baicalin,palmatine,berberine,wogonoside and benzoylpaeoniflorin,after which the content detemination was made by quantitative analysis of multi-components by single-marker(QAMS).RESULTS The characteristic chromatograms of 9 batches of formula granules and 15 bacthes of traditional decoctions demonstrated the similarities of more than 0.90 at the detection wavelengths of 192,210,240,260,280,300,320,360 nm,along with similar total peak areas.Eleven constituents showed good linear relationships within their own ranges(r＞0.999 0),whose average recoveries were 97.27％-101.64％with the RSDs of 0.36％-1.11％,the result obtained by QAMS and external standard method demonstrated no significant differences(P＞0.05).The contents of various constituents in the formula granules approximated those in the traditional decoctions.CONCLUSION The consistent kinds and contents of various constituents are obversable in formula granules and traditional decoctions of Gouteng Jiangya Formula,which can provide a reference for the reasonable clinical application of this formula.

Objective To investigate the application value of peripheral blood soluble human leukocyte antigen-G(sHLA-G)combined with immune cytokines in the differential diagnosis of renal transplant rejection.Methods This case-control study retrospectively analyzed 81 renal transplant patients hospitalized in the Department of Organ Transplantation,the Second Affiliated Hospital of Naval Medical University from April 2020 to December 2023,due to elevated serum creatinine.Among them,32 patients were diagnosed with acute rejection(acute rejection group),29 with chronic rejection(chronic rejection group),and 20 with elevated creatinine due to non-rejection causes(non-rejection group).Fifty renal transplant inpatients and outpatients with normal and stable serum creatinine were selected as control group during the same period.Clinical data such as gender,age,serum creatinine,estimated glomerular filtration rate(eGFR),and urine protein positive rate,etc.were collected.Peripheral blood of patients was sampled to measure the levels of plasma sHLA-G and immune cytokines[interferon-γ(IFN-γ),tumor necrosis factor-β(TNF-β),interleukin(IL)-2,IL-4,IL-10,IL-5,IL-6,IL-17]using enzyme-linked immunosorbent assay(ELISA).Stratify and compare the differences in sHLA-G levels among different groups and all renal transplant inpatients by gender.Results Compared with control group,serum creatinine levels and urine protein positive rate were significantly higher in acute rejection group,chronic rejection group,and non-rejection group,while eGFR was significantly lower,serum creatinine levels in chronic rejection group and non-rejection group were higher than those in acute rejection group,while eGFR was lower than that in acute rejection group,with statistically significant differences(P<0.05).No statistically significant differences were observed in gender,age,blood type,body mass index,transplantation duration,and immunosuppressive agent use among acute rejection,chronic rejection,non-rejection,and control groups(P>0.05).Plasma sHLA-G levels in acute rejection and chronic rejection groups were significantly lower than those in control group[(19.665±11.233)U/ml vs.(24.785±21.668)U/ml vs.(44.918±39.898)U/ml,P<0.05].The sHLA-G/IL-2 ratio in chronic rejection group was significantly higher than that in acute rejection group(5.844±6.248 vs.1.825±1.574,P<0.05),and the sHLA-G/IFN-γ ratio in non-rejection group was significantly higher than that in chronic rejection group(3.452±3.283 vs.1.543±2.030,P<0.05).Among 131 renal transplant inpatients,female sHLA-G levels were significantly higher than male(P<0.05).Within each group,female sHLA-G levels in chronic rejection group were significantly higher than male(P<0.05).Although female sHLA-G levels in acute rejection,non-rejection,and control groups were higher than those of male,the gender difference was not statistically significant(P>0.05).Conclusions Peripheral blood sHLA-G levels are correlated with renal transplantation rejection.The application of sHLA-G/IL-2 and sHLA-G/IFN-γ ratios has potential value in the diagnosis and differentiation of elevated creatinine caused by acute/chronic rejection,chronic rejection and non-rejection causes,respectively.

Objective To investigate the prevalence of specific IgE antibodies against Alternaria alternata and Aspergillus fumigatus in serum samples from clinical allergy patients across selected provinces in China.Methods Data on specific IgE antibodies for Alternaria A.and Aspergillus F.were collected from 20 hospital laboratories in 17 cities spanning 11 provinces.The study analyzed the levels of specific IgE and their variations across different provinces and seasons.Results A total of 27 471 cases of Alternaria A.and 32 843 cases of Aspergillus F.specific IgE data were included.The national average positive rate of Alternaria A.IgE was 10.40%,with the highest rate of 22.68%in Jiangsu and the lowest rate of 2.06%in Guangxi.For Aspergillus F.specific IgE,the average positive rate was 4.24%,with Hubei province having the highest rate(7.25%)and Hunan province the lowest(1.23%).The difference in IgE levels for both Alternaria A.and Aspergillus F.among provinces were statistically significant(H=9 955,16 993,all P<0.0001).Among patients,5.85%had Alternaria A.specific IgE levels at grade 3 or above,while only 0.57%had Aspergillus F.specific IgE levels at this level.When examining seasonal variations using data from Liaoning,Hunan and Anhui provinces,significant seasonal changes were observed for both Alternaria A.and Aspergillus F.IgE antibodies(HAlternaria A=347.6,338.0,401.3,HAspergillus F=196.6,133.7,231.7,all P<0.0001).Conclusion The sensitization to Alternaria A.and Aspergillus F.exhibits distinct geographical characteristics and vary significantly with seasons.Given the relatively high IgE levels associated with Alternaria A.,it should be given adequate clinical attention.

Objective:To explore the application value of right-opening single flap valvuloplasty based on tubular stomach in gastrointestinal reconstruction after laparoscopic proximal gastrectomy.Method:Use a linear cutting stapler to make a parallel curve from the angle of the stomach to the junction of the gastric fundus to remove the lesser curvature of the stomach, and detach the gastric body about 5 cm away from the tumor to create a tubular stomach. Use a marker pen to draw a C-shaped seromuscular flap area with a width of 2.5 cm and a height of 3.5 cm 1.5 cm below the residual stomach closure nail, and create a free muscle flap in the gap between the plasma muscle layer and the submucosal layer. Make a transverse incision of 3 cm at the lower edge of the mucosal bed, and intermittently suture the entire lower edge of the gastric wall with 3 stitches. Under laparoscopy, use 4-0 barbed wire to suture the 1 cm wide muscular layer at the top of the tubular stomach and the posterior wall of the esophagus about 5 cm away from the esophageal stump with 3 stitches. Push the upper end of the tubular stomach into the mediastinum, and then tighten the barbed wire to ensure a tight fit between the stomach and the posterior wall of the esophagus. Use an ultrasonic scalpel to remove the esophageal stump, suture the entire posterior wall of the esophagus with the gastric mucosa, and use barbed wire to suture the anterior wall from left to right. The anastomotic site is completely covered with a free muscle flap, and the barbed line is used to continuously suture the muscle flap along the C-shaped line to the gastric pulp muscle layer at the edge of the mucosal bed, embedding the anastomotic site and completing the reconstruction of the digestive tract.Results:Clinical data of 23 patients (18 from the First Affiliated Hospital of Wenzhou Medical University and 5 from the Quzhou Hospital affiliated with Wenzhou Medical University) who underwent laparoscopic proximal gastrectomy, tubular gastroesophageal anastomosis, and pure manual right flap reconstruction surgery for esophagogastric junction adenocarcinoma and proximal gastric cancer from October 2023 to August 2024. There were 15 males and 8 females, with an age of (65.3±7.7) years, the BMI was (22.9±2.8) kg/m 2. All patients in the group successfully completed the surgery, with a surgery time of (218.5±38.1) minutes, including (73.5±19.2) minutes for anastomosis, intraoperative blood loss of (64.5±15.4) ml, postoperative passage of gas on (3.4±0.5) days, first consumption of liquid food after surgery of (3.9±1.1) days, and postoperative hospital stay of (9.1±0.8) days. One patient developed anastomotic stenosis (grade I) after surgery, presenting with mild swallowing obstruction, which returned to normal after dietary adjustment, and there were no cases of secondary surgery. The median follow-up time for the entire group was 4.0 (0.7-7.0) months, during which there were no deaths or tumor recurrence or metastasis, no complications such as anastomotic stenosis or gastric emptying disorders, and no complaints of acid reflux or heartburn. At one month of postoperative follow-up, the reflux symptom index (RSI) score was (3.1±2.9) points, and at three months, the RSI score was (2.4±1.4) points. Conclusions:The application of right-opening single flap valvuloplasty based on tubular stomach for gastrointestinal reconstruction after laparoscopic proximal gastrectomy is safe,feasible,and has satisfactory short-term efficacy.

OBJECTIVES: To study the effect of prophylactic phenytoin (PHT) or levetiracetam (LEV) on busulfan (BU) blood concentration in children undergoing hematopoietic stem cell transplantation. METHODS: Pediatric patients conditioned with BU plus cyclophosphamide and fludarabine at the First People's Hospital of Chenzhou from September 2023 to February 2025 were retrospectively included. Patients were grouped by prophylactic antiepileptic regimen into PHT (n=24) and LEV (n=26). BU blood concentrations at the end of infusion (0 hour) and at 1, 2, and 4 hours post-infusion were compared between groups. RESULTS: At 0 hour post-infusion, BU blood concentrations did not differ significantly between groups (P>0.05). At 1, 2, and 4 hours post-infusion, BU blood concentrations were higher in the LEV group than in the PHT group (P<0.05). The area under the concentration-time curve from 0 to ∞ (AUC_0-∞) was greater in the LEV group (P<0.001), and the attainment rate of AUC_0-∞ was higher in the LEV group than in the PHT group (73% vs 21%, P<0.001). No significant differences were observed between groups in time to hematopoietic engraftment or in the incidence of BU-related adverse drug reactions (P>0.05). CONCLUSIONS Compared with PHT, LEV prophylaxis is associated with higher BU blood concentration and a higher AUC_0-∞ attainment rate. There is no observed difference in BU efficacy or safety between PHT and LEV.

OBJECTIVE: To examine the effectiveness of Chinese medicine (CM) Lianhua Qingwen Granule (LHQW) and Jingyin Gubiao Prescription (JYGB) in asymptomatic or mild patients with Omicron infection in the shelter hospital. METHODS: This single-center retrospective cohort study was conducted in the largest shelter hospital in Shanghai, China, from April 10, 2022 to May 30, 2022. A total of 56,244 asymptomatic and mild Omicron cases were included and divided into 4 groups, i.e., non-administration group (23,702 cases), LHQW group (11,576 cases), JYGB group (12,112 cases), and dual combination of LHQW and JYGB group (8,854 cases). The length of stay (LOS) in the hospital was used to assess the effectiveness of LHQW and JYGB treatment on Omicron infection. RESULTS: Patients aged 41-60 years, with nadir threshold cycle (C_T) value of N gene <25, or those fully vaccinated preferred to receive CM therapy. Before or after propensity score matching (PSM), the multiple linear regression showed that LHQW and JYGB treatment were independent influence factors of LOS (both P<0.001). After PSM, there were significant differences in LOS between the LHQW/JYGB combination and the other groups (P<0.01). The results of factorial design ANOVA proved that the LHQW/JYGB combination therapy synergistically shortened LOS (P=0.032). CONCLUSIONS Patients with a nadir C_T value <25 were more likely to accept CM. The LHQW/JYGB combination therapy could shorten the LOS of Omicron-infected individuals in an isolated environment.

Objective:This study aims to initially establish a scoring system for comprehensively reflecting the severity of intracranial atherosclerotic lesions and to explore the correlation between this score and atherosclerotic risk factors as well as stroke events.Methods:This study retrospectively analyzed patients who underwent head and neck computer tomography angiography(CTA)examinations and had head MRI examinations within one month before or after the CTA examination from January 2021 to August 2024 in Beijing Hospital.An intracranial atherosclerosis disease score(ICADS)system was constructed based on the degree and number of vascular stenosis.The relationship between ICADS and atherosclerotic risk factors was explored by grouping patients according to the quartile of ICADS.Patients were divided into acute stroke group and non-acute stroke group to compare differences in ICADS and cerebrovascular disease risk factors between the two groups, and to investigate the correlation between stroke events and ICADS.Results:There were statistically significant differences in the proportions of patients with hypertension and diabetes among different ICADS groups.Multiple linear regression analysis showed that hypertension( B=1.17, 95% CI: 0.20-2.14, P<0.05)and diabetes( B=2.75, 95% CI: 1.85-3.64, P<0.001)were risk factors for higher ICADS.The ICADS was higher in the acute stroke group than in the non-acute stroke group(9 vs.6, P<0.001), and a higher ICADS was identified as a risk factor for stroke( OR=1.10, 95% CI: 1.07-1.14, P<0.001). Conclusions:ICADS can comprehensively reflect the severity of intracranial atherosclerotic lesions and is correlated with stroke events, making it useful for clinical screening of high-risk patients for stroke.
