Objective:To explore the correlation of different HBV DNA loads with peripheral blood lymphocyte subsets and interleukin-6 (IL-6) in patients with chronic hepatitis B.Methods:A cross-sectional study was conducted. A total of 519 patients with chronic hepatitis B admitted to the Fifth Medical Center of the General Hospital of the People′s Liberation Army from April 2019 to June 2024 were included. The patients were divided into high, medium, and low viral load groups and a negative group based on HBV DNA load. Another 100 healthy individuals who underwent physical examinations during the same period were recruited as the control group. The quantities of peripheral blood lymphocyte subsets and IL-6 levels were compared among the groups. Meanwhile, alanine aminotransferase (ALT) levels were recorded and compared among the groups. The correlation of HBV DNA levels with lymphocyte subsets and IL-6 was analyzed using Pearson correlation analysis.Results:HBV DNA loads were negatively correlated with the counts of CD3 +, CD4 +, CD8 +, CD19 +, and CD56 + lymphocyte subsets (correlation coefficients r were -0.483, -0.508, -0.524, -0.573, and -0.561, respectively; all P<0.001) and positively correlated with IL-6 levels ( r=0.862, P<0.05). Compared with the control group, the counts of each lymphocyte subset were higher in the high, medium, and low viral load groups ( P<0.05). In the HBV DNA-negative chronic hepatitis B group, the counts of CD8 + and CD19 + lymphocyte subsets were significantly higher [712.32(526.00,898.64) and 495.62(345.74,645.50) cells/μl] than those in the control group [612.10(479.89,744.31) and 470.32 (396.00,544.64) cells/μl] ( P<0.05). Conclusion:The degree of HBV replication activity in patients with chronic hepatitis B is associated with the immune status of the body, and negatively correlated with the quantities of lymphocyte subsets and positively correlated with IL-6 levels.

Objective:To investigate the staging of cardiovascular-kidney-metabolic (CKM) syndrome before onset, and to analyze its impact on short-term prognosis in patients with acute myocardial infarction (AMI).Methods:The clinical data of 2 993 patients with AMI from January 2017 to December 2023 in Xuanwu Hospital, Capital Medical University were retrospectively analyzed. The basic information, baseline data, in-hospital data, cardiac-related examination results, CKM syndrome staging and in-hospital outcomes were recorded.Results:Among the 2 993 patients with AMI, the CKM syndrome stage 0 was in 23 cases (0.77%), stage 1 in 35 cases (1.17%), stage 2 in 2 015 cases (67.32%), stage 3 to 4 in 920 cases (30.74%). The male proportion, high density lipoprotein-cholesterol (HDL-C) and neutrophil-to-lymphocyte ratio in patients with CKM syndrome stage 0 and 1 were significantly higher than those in patients with CKM syndrome stage 2 and 3 to 4, the hypertension proportion, diabetes proportion, chronic kidney disease proportion, triglyceride (TG), glycated hemoglobin (HbA 1c) and creatinine were significantly lower than those in patients with CKM syndrome 2 stage 3 to 4, and there were statistical differences ( P<0.05); the body mass index (BMI) and non-ST-elevation myocardial infarction (NSTEMI) proportion in patients with CKM syndrome stage 0 were significantly lower than those in patients with CKM syndrome stage 1, 2 and 3 to 4, and there were statistical differences ( P<0.05); the cerebrovascular diseases proportion, Killip stage ≥3 proportion, N-terminal pro-brain natriuretic peptide (NT-proBNP) and left main coronary artery lesions proportion in patients with CKM syndrome stage 0, 1 and 2 were significantly lower than those in patients with CKM syndrome stage 3 to 4, and there were statistical differences ( P<0.05); the global registry of acute coronary events score (GRACE score) in patients with CKM syndrome stage 0 was significantly lower than that in patients with CKM syndrome stage 3 to 4, and there was statistical difference ( P<0.05). Although there were statistical differences in low density lipoprotein-cholesterol (LDL-C) and number of blood vessels involved among the four groups ( P<0.05), but pairwise comparisons showed no statistically significant differences ( P>0.05). There were no statistical differences in age, smoking history, hyperlipidemia, high-sensitivity C-reactive protein, uric acid, cardiac troponin I (cTnI) peak, left ventricular ejection fraction and left ventricular end-diastolic diameter among the four groups ( P>0.05). The incidence of in-hospital major adverse coronary events (MACE) was 10.76% (322/2 993). Among them, the incidence of MACE, all-cause mortality and longer length of stay in patients with CKM syndrome stage 0, 1 and 2 were significantly lower than those in patients with CKM syndrome stage 3 to 4: 4.35% (1/23), 8.57% (3/35) and 8.59% (173/2 015) vs. 15.76% (145/920), 0, 2.86% (1/35) and 2.38% (48/2 015) vs. 4.78% (44/920), (8.17 ± 3.87), (8.15 ± 5.32) and (8.89 ± 6.42) d vs. (9.81 ± 9.29) d, and there were statistical differences ( P<0.05); the incidences of acute kidney injury and atrial fibrillation in patients with CKM syndrome stage 0 and 1 were significantly lower than those in patients with CKM syndrome stage 2 and 3 to 4: 8.70% (2/23) and 8.57% (3/35) vs. 24.17% (487/2 015) and 34.35% (316/920), 0 and 0 vs. 3.52% (71/2 015) and 10.00% (92/920), and there were statistical differences ( P<0.05); there were no statistical differences in the incidences of ventricular tachycardia/ventricular fibrillation, cardiac arrest, mechanical complications and mechanical circulatory support among the four groups ( P>0.05). Conclusions:The severity of CKM syndrome is closely related to the occurrence of AMI. CKM patients with higher CKM stages have more severe AMI and poorer in-hospital prognosis. CKM syndrome staging can serve as a potential prognostic indicator for AMI patients.

OBJECTIVE To evaluate the therapeutic efficacy of 5 regimens of colistin sulfate for common Gram-negative bacilli infection based on pharmacokinetics(PK)/pharmacodynamics(PD)theory and Monte Carlo simulation.METHODS Minimal inhibitory concentration(MIC)data of colistin sulfate against Acinetobacter baumannii,Pseudomonas aeruginosa,Klebsiella pneumoniae,Escherichia coli and Enterobacter cloacae in 2023 were collected from the China Antimicrobial Resistance Surveillance System.Monte Carlo simulation was conducted with the ratio of the area under the concentration-time curve from 0 to 24 hours in the unbound state to the MIC(fAUC0-24 h/MIC)≥15 as the target value,the probabilities of target attainment(PTA)of 5 regimens of colistin sulfate to achieve the target ratio were obtained at different MIC;and the expected population PTA,specifically the cumulative fraction of response(CFR),for each regimen within a specific bacterial population was further calculated,to evaluate the therapeutic efficacy of the five colistin sulfate regimens.RESULTS When bacterial MIC≤0.5 μg/mL,PTA of all colistin sulfate regimens(500 000 IU,q12 h;500 000 IU,q8 h;750 000 IU,q12 h;750 000 IU,q8 h;1 000 000 IU,q12 h)were all more than 90%.When bacterial MIC=1 μg/mL,PTA for regimen(750 000 IU,q8 h)against A.baumannii,K.pneumoniae,P.aeruginosa,E.coli and E.cloacae,and for regimen(1 000 000 IU,q12 h)against the other four bacterial species(excluding P.aeruginosa)remained above 90%.When bacterial MIC≥2 μg/mL,PTA of 5 colistin sulfate regimens were all lower than 90%.For E.coli,the CFR of only colistin sulfate regimen(500 000 IU,q12 h)was less than 90%;for K.pneumoniae,the CFR of only colistin sulfate regimen(750 000 IU,q8 h and 1 000 000 IU,q12 h)was greater than 90%;for the other three bacteria,CFR of 5 regimens were all less than 90%.CONCLUSIONS When the MIC of Gram-negative bacteria is less than 0.5 μg/mL,colistin sulfate regimen with a routine dose can be selected for treatment.When MIC was 1 μg/mL,an increase in the dosing amount or frequency is required.The empirical treatment of the other four bacterial infections excluding E.coli requires the use of off-label doses.

Objective:To improve the diagnosis and treatment of thyroid carcinoma in flying personnel by analyzing the clinical characteristics of thyroid carcinoma.Methods:The clinical and pathological data of flying personnel with thyroid carcinoma diagnosed and treated by Air Force Medical Center of PLA from January of 2010 to December of 2022 were retrospectively analyzed. Clinical characteristics such as age, flying hours, aircraft types, thyroid function at diagnosis, and pathological characteristics such as tumor site, tumor size, lymph node metastasis, calcification and sand and Ki-67 positive ratio were collected, and the clinical and pathological characteristics were statistically analyzed.Results:Thyroid nodule was found as the first diagnosis of thyroid carcinoma in 57 flying personnel. The age of onset was 22-58 years old, the median age was 37 years old, the flying hours was 4-18 000 h, and the median flying hours was 2 000 h. Thyroid carcinoma was detected in both thyroid glands, and the histological type was papillary thyroid carcinoma. Thyroid function was normal in most cases when thyroid carcinoma was detected. Lymph node metastasis of thyroid carcinoma was low positively correlated with tumor size ( r=0.304, P=0.021), and was low positively correlated with the positive proportion of Ki-67 ( r=0.360, P=0.006). Other clinical and pathological characteristics did not show clear correlation. With the extension of flying hours, the incidence of lymph node metastasis of thyroid carcinoma increased, and the difference was statistically significant ( χ2=6.32, P=0.012). There was no statistical difference among the clinical characteristics of flying personnel with different age and aircraft types ( P>0.05). Conclusions:The thyroid carcinoma is usually diagnosed without clinical symptoms and the thyroid function is basically normal. The thyroid ultrasound examination should be emphasized during physical examination, and further examination should be conducted for the flying personnel with thyroid nodules.

Objective:To summarize the perioperative nursing points of percutaneous kyphoplasty (PKP) in elderly patients with osteoporotic vertebral compression fractures assisted by robots, so as to provide reference for orthopedic nursing.Methods:From July 2019 to February 2021, the data of 72 patients undergoing robot-assisted PKP in the spinal surgery of the First Affiliated Hospital of Anhui Medical University were retrospectively analyzed. The perioperative nursing points were summarized, and the nursing experience was summarized. The nursing under the new measures of precise minimally invasive treatment was analyzed and discussed. The length of hospital stay, postoperative ambulation time, complications and satisfaction survey results of patients were collected and recorded. The Numerical Rating Scale(NRS) score, Self-rating Anxiety Scale(SAS) score and Oswestry Disability Index (ODI) score before and after surgery were compared. The correlation analysis of the scores of various factors was combined to comprehensively evaluate the surgical and nursing effects.Results:All patients had no complications related to machine use during and after operation, and their symptoms were improved to varying degrees. Fifty-seven cases of indwelling catheter, catheter time (19.00±14.24) h. The preoperative hospitalization time was (6.16±2.22) d, and the postoperative hospitalization time was (1.94±0.99) d. Postoperative bed time was (16.34±6.81) h. Postoperative nursing satisfaction was (98.55±2.44)%.The postoperative NRS and SAS scores were (1.00±0.55) and (32.06±5.33) points, respectively, which were lower than those before operation (3.51 ± 0.71) and (39.08±8.86) points, and the differences were statistically significant ( t values were 33.976, 8.184, P<0.01). There were statistically significant differences in six indicators of ODI scores before and after surgery, including low back pain, walking, standing, sitting, sleep and self-care ( P<0.01). Correlation analysis showed that there was a strong correlation between the six ODI score factors and the NRS score. The four factors of sitting, walking, low back pain and standing were highly correlated with SAS. Conclusions:The implementation of good perioperative nursing management for patients with PKP assisted by robot can effectively promote the rehabilitation of patients, reduce the incidence of complications and improve patient satisfaction.

A 71-year-old male patient with advanced lung adenocarcinoma received pemetrexed (0.8 g, IV infusion on the first day) and carboplatin (500 mg, IV infusion on the first day) combined with pembrolizumab (200 mg, IV infusion on the second day) and 21 days was a cycle. Before the third cycle of treatment, the patient developed palpitations, irritability, increased appetite, and emaciation. Laboratory tests showed triiodothyronine (T 3) 2.88 nmol/L, thyroxine (T 4) 247.90 nmol/L, free triiodothyronine (FT 3) 10.57 pmol/L, free thyroxine (FT 4) 39.63 pmol/L, thyroid stimulating hormone (TSH) 0.014 mU/L, anti-thyroglobulin antibody (TGAb) 15.9 μg/L, thyroid peroxidase antibody (TPOAb) >1 300.0 kU/L. Immunerelated hyperthyroidism was considered, which may be related to pembrolizumab. The above-mentioned treatment was continued due to the patient′s condition, and thiamazole and metoprolol were given orally at the same time. One month later, laboratory tests showed T 3 2.50 nmol/L, T 4 153.40 nmol/L, FT 3 7.70 pmol/L, FT 4 33.61 pmol/L, TSH 0.007 mU/L, TGAb 15.7 μg/L and TPOAb >1 300.0 kU/L; 2 months later, laboratory tests showed T 3 1.84 nmol/L, T 4 81.20 nmol/L, FT 3 3.86 pmol/L, FT 4 11.56 pmol/L, TSH 1.979 mU/L, TGAb 15.7 μg/L, and TPOAb >1 300.0 kU/L.
