Purpose To assess the left ventricular global systolic function changes using three-dimensional speckle tracking imaging (3D-STI) in female patients with subclinical hypothyroidism (SHT) undergoing L-thyroxine treatment. Materials and Methods Thirty-eight female patients with SHT and 40 healthy female volunteers of the same age (control group) were selected, all the SHT patients received L-thyroxine therapy and were followed for 1 year after euthyroid status was achieved; all the participants underwent blood biochemical examinations, complete conventional echocardiographic and 3D-STI examinations, left ventricular end-diastolic diameter (LVEDd), left ventricular end-systolic diameter (LVEDs), interventricular septal depth (IVSd), left ventricular posterior wall depth (LVPWd), left atrial diameter (LAD), diastolic mitral flow spectrum of A peak, left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), and left ventricular ejection fraction (LVEF) of the two groups were compared, and the correlation of parameters of three dimensional left ventricular global longitudinal strain (GLS), global circumferential strain (GCS), global radial strain (GRS), global area strain (GAS), and thyroid stimulating hormone (TSH) with each parameter was analyzed. Results IVSd and LVPWd in the study group were higher than those of the control group (t=3.30 and 3.64, P<0.05). Compared with the control group, GLS, GCS, GRS and GAS of left ventricular of SHT patients in the study group were significantly lower (t=8.60, 11.95, 9.78 and 5.92, P<0.05) before treatment. GLS, GCS, GRS and GAS of SHT patients improved after L-thyroxine therapy, and the difference was statistically significant (t=6.91, 9.41, 6.46 and 4.31, P<0.05).TSH level was negatively correlated with E/A ratio and E (r= - 0.39 and - 0.42, P<0.05), and also negatively correlated with GLS, GCS, GRS and GAS (r= - 0.38, - 0.56, - 0.33 and - 0.41, P<0.05). Conclusion Left ventricular global systolic function changes of SHT patients before and after L-thyroxine treatment can be evaluated properly using 3D-STI.

Objective To detect the levels of homocysteine (Hcy) and anti-phospholipid antibodies (APLA) in the hematoplasma of the patients with deep venous thrombosis (DVT), discuss the reason of DVT recurrence and search for the predictors of it. Methods Sixty cases with DVT in our department from January 2001 to April 2003 were collected, which were divided equally into two groups as primary and recurrent, and first degree relative of the 30 DVT recurrent patients were also collected. The author established a control group using 30 cases of out-patient clinic without varicose veins of lower extremity or insufficient venae profundae. Hcy was detected with fluorescence polarization immunoassay (FPIA) and APLA 〔anticardiolipin antibody, ACLA (IgG, IgM); lupus antibody (LA)〕were detected with enzyme linked immunosorbent assay (ELISA). Odds ratios (OR) were also calculated to assess the relative risk of each study group. Results The values of Hcy and ACLA (IgG, IgM) in the primary group and recurrent group were both significantly higher than those of control group and first degree relative group of DVT recurrent patients (P

Objective To investigate the diagnosis value of p16 combined with Ki67 protein in cervical lesions.Methods Totally 1 542 women with previous liquid-based cytology smear result of abnormality underwent a colposcopy-directed biopsy excision procedure.Biopsy specimens were detected by p16 and Ki67 immunostaining alongside hematoxylin and eosin (H&E) staining.A four-semiquantitative class was used to describe the immunohistochemical results.Results Biopsy results revealed 1 542 women included 473 women with negative for dysplasia (NEG),629 women with cervical intraepithelial neoplasia (CIN) Ⅰ,206 women with CIN Ⅱ,206 women with CINⅢ and 28 women with cervical squamous cell carcinoma (SCC).The averageage of this study population was 34.47 years.CINs mainly occurred in women aged 20-29 years and 30-39 years.The positive rates of p16 in NEG,CIN Ⅰ,CIN Ⅱ,CINⅢ and SCC were 15.22％,60.25％,98.06％,99.51％,100.00％ respectively,and the positive rates of Ki67 were 12.05％,63.12％,96.12％,98.06％,100.00％ respectively.p16 expression and Ki-67 expression significantly increased with disease progression (p16:r =0.758,P =0.000 ; Ki67:r =0.773,P =0.000).Expression level of p16 was positively related with Ki-67 (r =0.774,P =0.000).The positive expression rates of p16 and Ki-67 of NEG were significantly lower than those of CIN and SCC (p16:x2 =1 127.46,P =0.000;Ki67:x2 =1 316.85,P =0.000).The positive expression rates of p16 and Ki-67 were markedly higher in CIN Ⅰ than those in CINⅡ,CINⅢⅢ and SCC (p16:x2 =500.19,P =0.000;Ki67:x2 =603.23,P=0.000).Conclusion Women aged 20-39 years are key subjects for cervical cancer screening.p16 and Ki67 immunohistochemistry is important in the ancillary diagnosis of cervical lesions.

To understand epidemiological characteristics of Marek's disease virus (MDV) prevalent in china currently,3 Marek's disease (MD) strains were isolated and identified from white feather meat chickens vaccined with MDV CVI988 or 814 through necropsy,histopathological observation,virus isolation and IFA detection,named SDAU1501,SDAU1502 and SDAU1503,respectively.vIL8,pp38,MEQ gene of the three strains of MDV were amplified using PCR,and compared with reference strains.The homology between SDAU1501 and SDAU1502 and virulent strains was above 97％,suggesting some features of virulent strains;while meq gene of SDAU1503 lost P amino acid at the 194 th site as that in CVI988,But the distinctive 177 nucleotide insertion mutations was not existed,predicting that it may be a attenuated vaccine strain.New variations of MDV continued and different types of variants emerged,therefore,prevalence and genetic monitoring of MD should be proceeded;meanwhile,more attentions should be given to MDV vaccine development.

Objective: To investigate the current status of screen exposure among preschool children in Shanghai and its association with family screen environment, so as to provide a scientific basis for family screen management. Methods: Using a convenient sampling method, a total of 349 preschool children aged 4-6 years were selected from 36 kindergarten classes in Xuhui District and Pudong New Area in Shanghai during April to June in 2023. Demographic characteristics and family screen environment were surveyed through an online questionnaire. Screen exposure of children was assessed using a diary method, with parents recording the activities over a 7day period. Multiple Logistic regression analysis was employed to identify factors influencing childrens screen content. Results: The average daily screen exposure time for children was (61.2±40.2) minutes, with an average of (12.4±17.6) minutes spent on educational screen content, 80.8% predominantly watched noneducational screen content. The percentages of time spent on educational screen content for 4yearold boys, 4yearold girls, 5yearold boys, 5yearold girls, 6yearold boys, and 6yearold girls were 20.1%, 14.7%, 21.3%, 21.9%, 20.6%, and 26.9%, respectively. Multivariate Logistic regression showed that children aged 5yearold (OR=0.49, 95%CI=0.25-0.96) and 6yearold (OR=0.45, 95%CI=0.21-0.95) were negatively associated with more noneducational screen content (P<0.05). However, occasional (OR=2.02, 95%CI=1.09-3.75) and sometimes (OR=4.50, 95%CI=1.70-11.90) using electronic devices to calm young child when crying, as well as children using electronic devices without adult supervision (OR=1.81, 95%CI=1.01-3.24) were positively associated with more noneducational screen content (P<0.05). Conclusions Preschool children in Shanghai exhibit high exposure to noneducational screen content, and family screen environment and parentchild interaction are associated with noneducational screen exposure. Strategies for family screen management should be developed to regulate childrens screen exposure behaviors, allowing electronic devices to play a positive role in their developmental process.

OBJECTIVETo investigate the autopsy characteristics, pathologic type, malfomation and genetic characteristics of complete atrioventricular septal defect (CAVSD).

METHODSThirty five cases of CAVSD were collected from Maternal and Child Hospital of Haidian District during Jan.2003 to Jan.2015. Autoptic material, clinical history and chromosome examination were reviewed.

RESULTSAmong 35 cases of CAVSD between 18-38 gestational weeks, there were 26 cases with CAVSD A (74.3%, 26/35), 1 case with CAVSD B (2.8%, 1/35) and 8 cases with CAVSD C (22.8%, 8/35). Only CAVSD malformation was seen in 4 cases (11.4%, 4/35). Multiple malformations were seen in 31 cases (88.6%, 31/35). Combined malformations most frequently occurred in cardiovascular, respiratory and locomotor system. Among 15 cases with chromosome examination, chromosome aberrations was found in 13 cases (13/15) and trisomy-21 was found in 11 cases (11/15).

CONCLUSIONSCAVSD is a rare disease and CAVSD A is the most common type. CAVSD is usually combined with other malformations and chromosome aberrations.

Objective:To investigate the influence of T2DM Spleen-qi Deficiency syndrome on Ankle-Brachial Index (ABI).Methods:The clinical data of 298 patients with T2DM who were hospitalized in Dongzhimen Hospital, Beijing University of Chinese Medicine from January 2019 to December 2021 were retrospectively analyzed. According to the diagnostic criteria of spleen-qi deficiency syndrome, the patients were divided into two groups: spleen-qi deficiency syndrome group and non-spleen-qi deficiency syndrome group. There were 142 patients in the spleen-qi deficiency syndrome group and 156 patients in the non-spleen-qi deficiency syndrome group. The differences of ABI between the two groups were compared, and the correlation between spleen-qi deficiency syndrome and clinical indicators (gender, age, body mass index, course of diabetes, history of hypertension, smoking history, fasting glucose, total cholesterol, triglyceride, platelet, hemoglobin, serum albumin, blood urea nitrogen, serum creatinine, estimated glomerular filtration rate) and ABI in T2DM patients was analyzed.Results:The left ABI [1.09 (1.00, 1.19) vs. 1.13 (1.03, 1.22)] and the right ABI [1.09 (0.96, 1.17) vs. 1.12 (1.02, 1.20)] in T2DM spleen-qi deficiency syndrome group were significantly lower than those in non-spleen-qi deficiency group ( P<0.05).The left ABI was significantly correlated with spleen-qi deficiency syndrome ( r=0.122, P=0.035) and estimated glomerular filtration rate ( r=0.137, P=0.018), and the right ABI was significantly correlated with spleen-qi deficiency syndrome ( r=0.123, P=0.034) and PLT ( r=-0.115, P=0.047). After correcting for other confounding factors by multiple linear regression analysis, there was significantly correlation between spleen-qi deficiency syndrome and ABI. Conclusion:Compared with the non-spleen-qi deficiency syndrome group, T2DM patients in the spleen-qi deficiency group had a lower ankle-brachial index and were more likely to develop peripheral arterial disease.

Objective:To investigate clinical treatment regimens for ocular lesions in patients with severe ocular rosacea.Methods:A total of 28 patients (34 eyes) with severe rosacea complicated by blepharokeratoconjunctivitis were collected from outpatient department of the Affiliated Eye Hospital of Nanjing Medical University from December 1, 2019 to May 30, 2021. They were randomly divided into two groups: group A (13 cases, 16 eyes) topically treated with sodium hyaluronate 0.3% eye drops and levofloxacin 0.5% eye drops, and group B (15 cases, 18 eyes) topically treated with sodium hyaluronate 0.3% eye drops alone. Patients in both groups also received oral minocycline hydrochloride 100 mg every day for the first 2 weeks, and then 50 mg every day for the next 6 weeks. Meanwhile, all patients received same physical therapies such as meibomian gland massage, eyelid hot compresses and eyelid margin cleaning. LogMAR visual acuity, tear break-up time (BUT) , ocular surface disease index (OSDI) score, and meibomian gland function grading examination results in the two groups were recorded before and 8 weeks after treatment. Paired t test was used to compare within-group differences in the parameters before and after treatment, and two-independent-sample t test to compare intergroup differences after treatment. Results:After 8-week treatment, both group A and group B showed significantly increased LogMAR visual acuity ( t = 3.10, 2.15, P = 0.007, 0.046, respectively) , improved BUT ( t = 3.44, 2.85, P = 0.003, 0.011, respectively) , but significantly decreased OSDI scores ( t = 7.12, 9.33, respectively, both P < 0.001) and meibomian gland function scores ( t = 13.73, 16.82, respectively, both P < 0.001) compared with those before treatment. After treatment, no significant differences were observed in the LogMAR visual acuity ( P = 0.721) , BUT ( P = 0.189) , OSDI scores ( P = 0.808) and meibomian gland function scores ( P = 0.191) between the two groups. No adverse drug reactions occurred during the treatment. During the follow-up period (8 months or shorter) , no recurrence of ocular lesions was observed. Conclusion:Without topical antibiotics, oral minocycline hydrochloride combined with topical sodium hyaluronate eye drops is still effective for the treatment and prevention of recurrence of ocular lesions in patients with severe ocular rosacea.

Although immune checkpoint inhibitors(ICIs)are widely used in cancer therapy,showing great advantages and development potential,it is accompanied by a series of immune-related adverse reactions,of which myositis is a potentially fatal adverse event,which has attracted great attention.Herein,we reported a case of advanced esophageal cancer with myositis after treatment with camrelizumab,which was characterized by myasthenia gravis(MG)with myasthenic crisis,and recovered after active rescue by multidisciplinary cooperation.
