Streptococcus dysgalactiae subspecies equisimilis (SDSE) belongs to group C or group G β-hemolytic Streptococcus, SDSE infection cases are mostly related with the consumption of contaminated dairy or meat products, the major symptom is upper respiratory tract infection, and is easily to be misdiagnosed.In June 2014, an outbreak of acute upper respiratory tract infection due to SDSE occurred in a kindergarten in Xi'an City.All cases were followed up, the initial case developed as latent nephritis, the main cause for the development of latent nephritis was not performing diagnosis and treatment timely.In order to enhance the understanding of the epidemiological and clinical features of SDSE infection, strengthen prevention and control ability, and reduce the occurrence of adverse sequelae, investigation of the case and epidemic situation should be reported.

Objective To determine the iodine content of common foods in different geographical areas (coastal city,coastal rural area,mountainous city and rural area) in Fujian Province and provide basic data for evaluation of dietary iodine intake.Methods In 2010,based on the types of food of the total diet study,one food sample(consumption rate is greater than 1％) was collected in coastal city(Taijiang),coastal rural area(Xiang'an),mountainous city (Sanyuan) and rural area(Mingxi).These foods including cereal,beans,potato,meat,eggs,milk,aquatic products,vegetables,fruits,sugar,beverages,liquor and seasoning,and so on 184 kinds of common foods.The iodine content of these food was tested by As (Ⅲ)-Ce4+ catalytic spectrophotometry.Results Among the 184 kinds of food tested,164 were not indicated food iodine content in the Chinese Food Composition Tables (2004).The iodine content of common food in Fujian Province in descending order were salt (30 000 μg/kg),aquatic products(341.4 μg/kg),eggs(255.9 μg/kg),dairy(106.7 μg/kg),meat(103.2 μg/kg),cereals (40.7 μg/kg),vegetables(30.7 μg/kg),beans(12.9 μg/kg),sugar(8.5 μg/kg),fruits(6.7 μg/kg),potatoes(2.4 μg/kg) and alcohol(2.1 μg/kg).The iodine content of kelp and laver was the highest in all the food,which was 314 780.1,176 956.5 μg/kg,respectively.The iodine content of food from animal(241.4 μg/kg) was much higher than that of the food from plant(25.4 μg/kg).The iodine content of common cereals,potatoes,beans,sea algae,meat,eggs and aquatic products was compared in the four areas,and the difference was not statistically significant (M =135.5,20.0,42.0,16.0,54.0,4.0,x2 =1.4,all P ＞ 0.05).The iodine content of vegetables and fruits was compared,and the difference was statistically significant (x2 =8.5,M =204.5,all P ＜ 0.05).Conclusion The iodine content of different foods is different.

OBJECTIVETo investigate the clinical application of the ureteral dilation catheter combined with the balloon catheter under the ureteroscope in the treatment of urethral stricture in men.

METHODSUnder the ureteroscope, 45 male patients with urethral stricture received placement of a zebra guide wire through the strictured urethra into the bladder and then a ureteral dilation catheter along the guide wire, followed by dilation of the urethra from F8 initially to F14 and F16. Again, the ureteroscope was used to determine the length of the strictured urethra, its distance to the external urethral orifice, and whether it was normally located. An F24 balloon catheter and then a metal urethral calibrator was used for the dilation of the strictured urethra. After removal of the F18-F22 urethral catheter at 8 weeks, the urinary flow rate was measured immediately and again at 3 months.

RESULTSAll the operations were successfully performed without serious complications. The maximum urinary flow rate was (13.3-29.9) ml/s (mean [17.7 ± 3.2] ml/s) at the removal of the catheter and (15.2-30.8) ml/s (mean [19.8 ± 3.9] ml/s) at 3 months after it. Smooth urination was found in all the patients during the 6-24 months follow-up.

CONCLUSIONThe application of the ureteral dilation catheter combined with, the balloon catheter under the ureteroscope is a good option for the treatment of male urethral stricture for its advantages of uncomplicatedness, safety, effectiveness, few complications, less pain, high success rate, and repeatable operation.

Objective: To observe the clinical efficacy of tuina manipulations in treating different types of tic disorders (TD). Methods: Eligible TD patients were classified into three types, transient tic disorders (TTD), chronic multiple tic disorders (CMTD) and Tourette syndrome (TS), according to their disease duration and severity. The three types of children were treated with the same tuina manipulations. Changes in the Yale global tic severity scale (YGTSS) score, effective rate for tic, and cervical spine imaging examination results (including asymmetry of the lateral atlanto-dental interval, broadened anterior atlanto-dental interval, C2 spinous process deviation, occipito-atlanto-axial flexion/ extension instability) were observed after 1-month and 3-month treatments respectively. Results: The YGTSS score changed significantly after 1-month and 3-month treatments compared with that before treatment (both P<0.01); the effective rate for TD was 46.6％ and 86.7％ respectively after 1-month and 3-month treatments; there were significant differences comparing the effective rate for tic between different types of TD after 1-month and 3-month treatments (all P<0.05); comparing the effective rate for tic after 1-month treatment with that after 3-month treatment for the same type, the intra-group differences were statistically significant [TTD group (P<0.01), CMTD group (P<0.01), TS group (P<0.05)]; the abnormal parameter rates in neck imaging examination after 3-month treatment were significantly different from those before treatment (all P<0.01). Conclusion: Tuina manipulation is effective for TTD, CMTD and TS. It can correct the abnormal alterations of patients' cervical vertebrae, and its efficacy for TTD is most significant.

Acute myeloid leukemia (AML) is a genetic heterogeneous disease in which primordial and juvenile myeloid cells proliferate or accumulate abnormally in bone marrow, peripheral blood and other tissues, resulting in damage to normal hematopoietic function. Studies have shown that about 30% of AML patients have FMS-like tyrosine kinase 3 (FLT3), FLT3 abnormal regulation is closely related to the occurrence and development of AML. At present, FLT3 has become an important target for developing small molecular targeted drugs. Currently, a variety of FLT3 inhibitors and FLT3 degraders have been developed targeting FLT3, and some compounds have exhibited good anti-AML activity. This article summarizes and sorts out the current mainstream drugs for AML therapeutic targeting FLT3, in order to provide a reference for the development and design of AML drugs.

Objective: To understand characteristics of men who have sex with men (MSM) who applied for HIV antibody self-testing reagents through "AIDS self-testing" column of a WeChat official account named "Dark Blue Public Health Center" in Tianjin City, so as to provide insights into exploring online modes of HIV antibody self-testing for MSM. Methods: Data of MSM who were 18 years old or above, currently lived in Tianjin City, had sex with men in the past six months and applied for HIV antibody self-testing reagents through "AIDS self-testing" column from May 2018 to December 2022 were collected. Demographic characteristics, results return and positive findings were descriptively analyzed. Results: Data of 2 064 MSM were collected, including 1 052 MSM aged 20 to 29 years (50.97%), 1 522 unmarried MSM (73.74%), 545 workers (26.41%), 1 385 MSM with college education or above (67.10%), and 315 MSM without testing for HIV antibody in the past (15.26%). A total of 6 470 self-testing reagents were applied, and 5 942 testing results were returned, with a return rate of 91.84%. There were 33.28% (687/2 064) of the applicants applying for 66.32% (4 291/6 470) reagents multiple times. There were 73 MSM with positive results, accounting for 1.23%. Conclusions The MSM applying for HIV antibody self-testing reagents through "AIDS self-testing" are mainly young and highly educated, including some who have never tested for HIV. However, attention should be paid to duplicate applications and the return rate should be increased.

Objective To evaluate the impact of breathing motion on target volume and the factors influencing the set-up errors during tangential whole breast irradiation.Methods From Jan 2003 to Dec 2003,patients with early-stage breast cancer after breast conserving surgery,were selected to be eligible for the study.All patients were immobilized in treatment position by breast beard of Med-Tec 250.The motion of the breast treatment volume was observed on a fluoroscope in different directions under free breathing in 16 patients.The set-up errors in different dimensions during irradiation were measured by weekly portal films (PF) in comparison with digital reconstructed radiographs (DRR) in 11 patients.Results The central lung distance (CLD) variation during free breathing was (2.1?1.2) mm which is greater than the motion to- wards the other directions.By comparing the PF and DRR,the systemic error,random error and overall er- ror in the outer,inner and cranio-caudal directions was 1.9,1.6,2.5 and 2.4,1.7,3.1 and 2.6,2.3, 3.5 mm,respectively.In addition,the discrepancy of the treatment position in cranio-caudal direction and breast volume was most obvious at the beginning 2 weeks with the peak of breast volume at the second week. It decreased gradually during the following 3 weeks.Conclusions This study suggests that the mean value of the motion of the breast target volume during one breathing cycle is less than 2 mm.The set-up errors dur- ing irradiation is the greatest in cranio-caudal direction,suggesting that the fixing precision of the breast board should be further improved.The set-up error during irradiation are most obvious at the beginning two weeks,with the peak of the breast volume in the second week.

Kidney injury and decreased chemosensitivity of tumor cells are obstacles with cisplatin (CDDP) chemotherapy. Down-regulation of the organic cation transporter 2 (OCT2) and multidrug resistance-associated protein 2 (MRP2) is a key means to alleviate CDDP-induced kidney injury and increase chemosensitivity. Astragaloside IV (AS IV) is obtained from the well-known traditional Chinese herb Astragalus membranaceus. This study explored the role of AS IV in preventing kidney injury and enhancing the antitumor effect of CDDP by suppressing OCT2 expression in kidney and MRP2 in tumors. This project was reviewed and approved by the Animal Ethics Committee of the First Hospital of Jilin University. The effects of AS IV on CDDP inhibition of tumor growth and promotion of apoptosis were assessed in Lewis lung tumor (LLC)-bearing mice by H&E and TUNEL staining. Kidney injury was assessed by serum biochemical parameters and H&E staining. We used Western blotting and immunohistochemistry assays to detect OCT2 and MRP2 expression in kidney and tumor. The concentration of CDDP in kidney and tumor was measured by HPLC-MS/MS. AS IV enhanced CDDP chemosensitivity by increasing tumor cell apoptosis and slowing tumor growth, and decreased kidney injury as evidenced by lower blood creatinine (Cr) and blood urea nitrogen (BUN). Co-administration of AS IV suppressed MRP2 overexpression induced by CDDP in tumor tissues and may be an important mechanism for enhancing CDDP chemosensitivity. Moreover, AS IV reduced CDDP-induced kidney injury in mice along with suppression of OCT2 expression in kidney. The concentration of CDDP was increased in tumor but decreased in kidney. In total, AS IV not only enhanced the antitumor effect of CDDP by suppressing MRP2 expression in tumor cells, but also decreased kidney injury induced by CDDP. The results provide new insight into the combined use of a chemotherapy drug and natural ingredients to treat cancer.
