Objective To explore the ultrasonographic, clinical and histopathological characteristics features of primary uterus lymphoma. Methods The clinical, sonographic and histopathological characteristics of nine patients who were pathologically comfirmed as primary uterus lymphoma were analyzed. Results Among the nine cases of primary uterus lymphoma, three lesions were found in the uterine bodys and 6 were found in the cervixes. Two patients with uterine body lymphoma had painless pelvic masses and six patients with cervix lymphoma had contact bleeding, including irregular vaginal bleeding in four patients. In sonograms, six lesions showed remarkable hypoechogenicity with homogeneous internal echogenicity;the margins of most lesions were circumcribed;all lesions had posterior enhancement. In color Doppler lfow imaging, abundant vascularities were detected in eight lesions. In the cases of uterine body lymphoma, all of the uterine bodys showed diffuse symmetrical enlargement without disruption of the endometria, while in ifve cases of cervix lymphoma, the tumors showed the shape of lobule. The pathological examination showed that all tumors were diffuse B-cell type non-Hodgkin lymphoma. Conclusions Primary uterus lymphoma has some clinical and ultrasonic features, including contact bleeding or irrgular vaginal bleeding, diffuse symmetrical enlargement of uterine body, complete endometria, remarkable hypoechogenicity, homogeneous echogenicity and posterior enhancement. Final diagnosis depends on the histopathology.

OBJECTIVETo observe the clinical effect of Ziyin Huoxue Granule (ZHG) combined glucocorticoids and antibiotics in treatment of radiation pneumonitis.

METHODSTotally 70 radiation pneumonitis patients were assigned to the treatment group and the control group according to random digit table, 35 in each group. All patients received glucocorticoids and antibiotics. Patients in the treatment group additionally took ZHG, one dose per day for 4 successive weeks. Watters clinical-radiologic-physiologic (CRP) score, Karnofsky Performance Status Scale (KPS) , and acute radiation injury classification [set by Radiation Therapy Oncology Group (RTOG)] were observed in the two groups before and after treatment. The application time for antibiotics and glucocorticoids was compared between the two groups.

RESULTSAll patients completed this trial, and nobody dropped out or died. There was no statistical difference in Watters-CRP scores, KPS, or RTOG between the two groups before treatment (P > 0.05). Compared with before treatment in the same group, RTOG classification was obviously improved in the two groups (P < 0.05). Compared with the control group, Watters-CRP scores decreased, KPS increased, the application time for antibiotics and glucocorticoids was reduced (P < 0.05). The efficacy of RTOG classification was better in the treatment group than in the control group, but with no statistical difference between the two groups (P > 0.05).

CONCLUSIONZHG combined glucocorticoids and antibiotics was superior in treating radiation pneumonitis to using glucocorticoids or antibiotics alone in elevating Watters-CRP scores, shortening the application time for glucocorticoids and antibiotics, and improving patients' physical conditions.

Abstract: Objective　To investigate the fundus arteriosclerosis and its influencing factors in HIV/AIDS patients after long-term highly active antiretroviral therapy (HAART). Methods　The clinical basic data and fundus examination data of 203 HIV/AIDS patients before and after HAART in the Fourth People 's Hospital of Nanning from January 2020 to June 2022 were collected to evaluate the occurrence of fundus arteriosclerosis and analyze its influencing factors. Results　Of the 203 HIV/AIDS patients, 159 patients developed fundus arteriosclerosis, with an incidence of 78.33%, including 33 patients with grade Ⅰ(20.75%), 87 patients with grade Ⅱ (54.72%), 28 patients with grade Ⅲ(17.61%), and 11 patients (6.92%) with Grade Ⅳ. Before HAART, there was no significant difference in CD4+T lymphocyte count, CD8+T lymphocyte count, viral load, white blood cell count, platelet count, hemoglobin, serum creatinine, blood urea nitrogen, triacylglycerol, total cholesterol, fasting blood glucose, alanine aminotransferase, aspartate aminotransferase and serum total bilirubin between the atherosclerosis group and normal group (P>0.05). After 6 months of HAART, CD8+T lymphocyte count, triacylglycerol and fasting blood glucose in atherosclerosis group were significantly higher than those in normal group (P<0.05). In the stratified comparison of CD4+ and CD8+ lymphocyte counts after 6 months of HAART, the proportion of patients with CD4+ lymphocyte count (CD4+)<200 (cells/μL) in the atherosclerosis group was significantly higher than that in the normal group; the proportion of patients with CD4+ lymphocyte count (CD4+)≥500 (cells/μL) was significantly lower than that in the normal group; the proportion of patients with CD8+ lymphocyte count CD8+≥ 800/μL was significantly higher than that in the normal group (all P<0.05). Binary logistic regression analysis showed that opportunistic infection, HIV course, CD4+T, CD8+T lymphocyte count after HAART and triglyceride were independent risk factors for ocular fundus atherosclerosis in HIV/AIDS patients (all P<0.05). Conclusions　The incidence of ocular fundus arteriosclerosis is high in HIV/AIDS patients. More than 4 years of HIV course, combined opportunistic infection, Low CD4+T lymphocyte count after 6 months of HAART, high CD8+T lymphocyte count and high triglyceride level are independent risk factors for ocular fundus arteriosclerosis in HIV/AIDS patients. Fundus screening should be performed before and after HAART in such population, HAART program should be formulated for the risk of cardiovascular disease, and risk management of cardiovascular disease should be strengthened during treatment to improve patient outcomes.

Abstract: Objective To investigate the impact of SARS-CoV-2 virus infection on the risk of thrombosis in COVID-19 outpatient patients with mild and regular symptoms. Methods Outpatient patients during the SARS-CoV-2 large-scale infection period after the policy adjustment for COVID-19 in Beijing in 2022 were selected as the observation group, and the dynamic zero-clearing period before the policy adjustment and outpatient patients during the 2022/2021/2020 period were taken as the three control groups. The patients with physiological factors that may increase the risk of coagulation, such as thrombotic diseases, malignant tumors, female pregnancy and other physiological factors, were excluded. Pediatric patients under 14 years old were also excluded. Age was expressed as median (interquartile). The changes in blood routine, fibrin/fibrinogen degradation products, and D-Dimer in Beijing outpatient patients were studied with statistical method and data analysis techniques. Results Compared with the control groups, the observation group showed a statistically significant decrease in red blood cells (RBC), hemoglobin (Hb), and hematocrit (HCT) levels, and an increase in monocytes (MONO) and platelet (PLT) counts, all showed statistically significant differences (P<0.0001). The proportion of fibrinogen degradation product (FDP) and D-Dimer of observation group exceeding the range increased significantly. Compared with the three control groups, the number of outpatient fibrinogen degradation products (FDP) in the observation group of patients aged 50 years and verage number of patients under 50 years old in the observation group with D-Dimer exceeding the threshold increased by more than 48.98%, and the monthly average number of patients with D-Dimer exceeding the threshold in patients aged 50 or older increased by 346%-998%. Conclusions The results of this study suggest that outpatient patients with mild or regular SARS-CoV-2 infection are also at risk for thrombotic events, and monitoring blood coagulation indicators such as D-dimer is recommended to avoid the sudden onset of thrombosis-related fatal complications .

Objective To construct cDNA entry library and cDNA expression library of Armillifer agkistrodontis (A.) nymphs and make a preliminary immunoscreening for the cDNA expression library.Methods The nymphs were collected from the Kunming mice infected experimentally with A.agkistrodontis eggs and the total RNA were extracted from the nymphs using TRIzol Reagent.After purifying the mRNA,the synthesized cDNAs were cloned into the donor vector pDONR222 by BP reaction of Gateway technology and the recombinants were transformed into the DH10B cells by electroporation,the cDNA entry library was obtained.Next,the expression vector pDEST17 was ligated with entry clones by LR reaction,and the recombinants were transformed into the BL21 (DE3) cells.Hence,the cDNA expression library was constructed.Then,the expression library was immunoscreened with the mixed sera of mice infected with A.agkistrodontis,and the insertions of positive clones were sequenced.After that,the open reading frame(ORF) of positive slone sequence,the homology of the screened genes and their encoded proteins were analyzed by Finder and BLAST (basic local alignment search tool) program of National Center of Biotechnology Information(NCBI),and the discovered new genes were submitted into the GenBank.Besides,the physico-chemical properties,secondary structure and B cell epitopes of encoded proteins were also analyzed by bioinformatics software.Results The average titer and total clones of the cDNA entry library were 1.45 × 105 CFU/ml(colony-forming unit,CFU) and 1.74 × 106 CFU,respectively,and the range of fragment length of the inserted cDNA was between 0.2-4.0 kb,with an average of 1.4 kb.The total clones of cDNA expression library were 1.00 × 105 CFU,and the fragment length of the inserted cDNA was between 0.3-2.2 kb,with an average of 1.0 kb.Five positive clones,coded S1,S5,A1,D1 and F1,respectively,were obtained through preliminary immunoscreening.The sequence and homology of the five positive clones were sequenced and analyzed by BLAST program.No significant similarities were found in pentastomida species,which meant that they were all novel genes of A.agkistrodontis.The gene sequences were submitted to GenBank,with the accession number from JQ180451 to JQ180455.Also,results obtained by bioinformatics software showed that the predictive encoding proteins were all potential to be valuable recombinant diagnostic antigens.Conclusions The cDNA library of A.agkistrodontis nymphs is successfully constructed,and five new genes of A.agkistrodontis are discovered.The establishment of cDNA library and the discovery of the new genes will lay a foundation for further studying the gene functions and screening the immunodiagnostic antigens.

Objective To explore the correlation between hypokalemia and sudden death in young and middle-aged people. Methods One hundred and twenty-nine young and middle-aged patients with sudden death during treatment were selected as observation group. Then 100 cases of healthy volunteers were randomly selected as control group. The incidence of cardiovascular disease, incidence of hypokalemia and intake of potassium were compared between 2 groups. Results The incidences of hypertension, arrhythmia, myocardial infarction, heart failure and hypokalemia in observation group were significantly higher than those in control group: 17.05% (22/129) vs. 5.00%(5/100), 13.18% (17/129) vs. 2.00% (2/100), 26.36% (34/129) vs. 9.00% (9/100), 9.30% (12/129) vs. 1.00% (1/100) and 55.04% (71/129) vs. 12.00% (12/100), and there were statistical differences (P<0.01). The ratios of higher, common, lower intake of potassium in observation group were 1.55%(2/129), 27.91% (36/129) and 70.54%(91/129), in control group were 15.00% (15/100), 58.00% (58/100) and 27.00% (27/100), and there was statistical difference (P<0.01). Logistic regression analysis result showed that hypertension, arrhythmia, myocardial infarction, heart failure, hypokalemia and lower intake of potassium were the risk factor for sudden death (P<0.01). The incidences of hypertension, arrhythmia, myocardial infarction and heart failure in hypokalemia patients were significantly higher than those in normokalemia patients: 28.92% (24/83) vs. 2.05% (3/146), 19.28% (16/83) vs. 2.05% (3/146), 44.58%(37/83) vs. 4.11% (6/146) and 13.25% (11/83) vs. 1.37% (2/146), and there were statistical differences (P<0.01). The incidence of hypokalemia in people with lower intake of potassium was significantly higher than that in people with higher and common intake of potassium: 56.78% (67/118) vs. 2/17 and 14.89%(14/94), and there was statistical difference (P<0.01). Conclusions There is a significant correlation between hypokalemia and sudden death in young and middle-aged people. Preventive measures of sudden death should be made according to serum potassium level in clinic. People should pay attention to the uptake of potassium in daily life.
