The ultrasonic estimation of fetal weight at delivery is of important prognostic significance in obstetrical practice. The convertional regression formulas used for estimating fetal weight have the disadvantage of less reliability. In this study, we used the back propagation neural network (BP) to estimate Fetal Weight. Some input variables were adopted in constructing the BP model: biparietal diameter (BPD), cerebellum transverse diameter (TCD), abdominal circumference (AC), liver length (LL), femur length (FL), fetal thigh soft tissue thickness (FSTT), and gestational age (GA). The fetal weights of 109 singleton fetuses were estimated. In the training group and validation group, coincidence rates were 89.77% and 76.19% respectively. The results show that the estimation based on neural network is more accurate than that by regression method. GA, its unit is not week but day in our formulas, is very valuable in combination with other ultrasonic parameters on estimation.

Objective:To investigate the seroepidemiological status of Toxoplasma gondii among humans, dogs and cats and its influencing factors in three counties of Yunnan Province, and to assess the risk of dogs and cats transmitting Toxoplasma gondii to humans and causing disease and epidemics. Methods:Three pestis foci of demestic rodent in Mile City, Mang City and Lianghe County in Yunnan Province were selected as the investigation areas, and blood samples of humans, dogs and cats from 16 natural villages were collected. Serum IgG antibodies against Toxoplasma gondii were detected by indirect enzyme-linked immunosorbent assay, and the influencing factors were analyzed by logistic regression. Results:A total of 368 human serum samples, 307 dog serum samples, and 12 cat serum samples were tested. The positive rates of serum IgG antibodies against Toxoplasma gondii in humans, dogs and cats were 54.62% (201/368), 90.88% (279/307), and 91.67% (11/12), respectively. Logistic regression analysis showed that the risk of Toxoplasma gondii infection (serum IgG antibodies positive) in humans of Mang City and Lianghe County were 8.20 times ( AOR = 8.20, 95% CI: 4.38 - 15.36) and 2.22 times ( AOR = 2.22, 95% CI: 1.24 - 3.97) higher than those in Mile City, respectively, and the risk of Toxoplasma gondii infection (serum IgG antibodies positive) in humans in the age group of 30 - < 40 years old decreased by 57% compared to the age group of 30 years old ( AOR = 0.43, 95% CI: 0.19 - 0.98, P < 0.10). The risk of Toxoplasma gondii infection (serum IgG antibodies positive) in dogs of Lianghe County was 89% lower than that in Mile City ( AOR = 0.11, 95% CI: 0.02 - 0.47). The risk of Toxoplasma gondii infection(serum IgG antibodies positive) in dogs aged 2 years old and older was 2.05 times higher than that in dogs aged younger than 2 years old ( AOR = 2.05, 95% CI: 0.91 - 4.64, P < 0.10). Conclusions:The positive rates of serum IgG antibodies against Toxoplasma gondii in humans, dogs and cats in the three counties where the three pestis foci of demestic rodent are located in Yunnan Province is relatively high. The risk of Toxoplasma gondii infection (serum IgG antibodies positive) in humans, dogs is related to the region and age. The risk of dogs and cats transmitting Toxoplasma gondii to humans and other animals is relatively high. It is necessary to strengthen monitoring in key regions, carry out health education, and take corresponding health measures.

Objective To analyze the reported data of national rural cervical cancer screening project from 2012 to 2013 and to evaluate the project implementation condition. Methods Data of the national breast carcinoma and cervical cancer (two-cancer) screening project for rural women were collected from the online report system of key women and children's public health service programs.The screening items included: preliminary screening of cervical lesions (cervical cytology, using Traian Bethesda System (TBS) or Pap grading for classification and reporting), acetate/iodide staining (VIA/VILI), colposcopy, histopathological examination, and pathological diagnosis. The study collected the quarterly reported data from 1 183 counties of 30 provinces in 2014 and 1 130 counties of 30 provinces in 2013. Chi-square test was used to test the difference of positive detection rate, as well as precancerous cervical lesions, and cervical cancer detection rates among difference preliminary screening methods in 2012 and 2013. Results In 2012 and 2013, the number of cervical cancer screening was 10 621 482 and 10 321 835. The percentage of using ThinPrep cytological test as the screening method was 77.17%(n=8 196 627) and 77.07%(n=7 954 949) in 2012 and 2013, respectively. Among these ThinPrep cytological tests in these two years, 65.49%(n=5 368 194) and 71.67% (n=5 701 033) used TBS report system. The abnormality rate of colposcopy increased from 27.29% (170 063/623 161) to 31.15% (203 397/652 935) (χ2=2 295.94, P<0.001). The abnormality rate of histopathology test increased from 19.54% (37 992/194 394) to 35.43% (59 004/166 518) (χ2=11 523.58,P<0.001). All together, 27 341 cervical cancer or precancerous lesions have been detected in these two years. The detection rate of invasive cervical cancer increased from 18.02/100 000 in 2012 to 19.71/100 000 (χ2=7.90, P=0.005) in 2013 and that of precancerous lesions rose from 106.85/100 000 to 119.26/100 000 (χ2=70.82, P<0.001). The early detection rate was 89.60% (11 883/13 263), and 89.57%(12 609/14 078), respectively in 2012 and 2013. In these two years, the rank of the detection rate of each cervical lesion were CIN1, CIN2, CIN3, invasive carcinoma, adenocarcinoma in situ, and microinvasive carcinoma, from the highest rate to the lowest rate. Conclusion The program has achieved certain screening effect and the screening method has been improved. However, the quality of colposcope and histopathology should be enhanced.

ObjectiveTo investigate the mechanism of topical treatment of allergic contact dermatitis (ACD) mice with Portulacae Herba based on the nuclear factor E2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1)/nuclear factor-κB (NF-κB) signaling pathway. MethodsA total of 70 6-week-old specific pathogen free (SPF) female Kunming mice were adaptively fed for 1 week and randomly divided into blank group, model group, compound dexamethasone acetate cream group (2.075×10-2 g·g-1), blank matrix cream group, low-dose Portulacae Herba cream group (0.1 g·g-1), high-dose Portulacae Herba cream group (0.2 g·g-1), and Portulacae Herba + inhibitor group (0.2 g·g-1 + 30 mg·kg-1 ML385), with 10 mice in each group. One day before the experiment, the mice were shaved on the neck and back. Except for the blank group, the mice in the other groups were treated with 2,4-dinitrochlorobenzene (DNCB) to establish an ACD model. After respective administration, the skin lesion of the mice was scored, and the histopathological changes of the skin were stained with hematoxylin-eosin (HE). Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of interleukin-6 (IL-6), interleukin-1β (IL-1β), reactive oxygen species (ROS), superoxide dismutase (SOD) activity, and malondialdehyde (MDA) in serum of mice. The expression of Nrf2/HO-1/NF-κB signaling pathway-related proteins in mouse skin tissue was detected by immunohistochemistry (IHC), Western blot, and real-time fluorescence quantitative polymerase chain reaction (Real-time PCR). ResultsCompared with the blank group, the mice in the model group had an increased skin lesion score (P<0.01), severe pathological damage to skin tissue, increased content of IL-1β, IL-6, ROS, and MDA in their serum (P<0.01), and decreased content of SOD (P<0.01). In addition, the mRNA and protein expression levels of Nrf2, HO-1, and nuclear factor-κB inhibitor α (IκBα) in skin tissue were up-regulated (P<0.01), while the protein expression levels of phosphorylated (p)-IκBα and p-NF-κB p65 and the mRNA expression of NF-κB p65 were down-regulated (P<0.01). Compared with the model group and the blank matrix cream group, the mice treated with Portulacae Herba had a decreased skin lesion score (P<0.01), reduced pathological damage to skin tissue, decreased content of IL-1β, IL-6, ROS, and MDA in their serum (P<0.01), and increased content of SOD (P<0.01). Additionally, the mRNA and protein expression levels of Nrf2, HO-1, and IκBα in skin tissue were down-regulated (P<0.05,P<0.01), and the protein expression levels of p-IκBα and p-NF-κB p65 and the mRNA expression of NF-κB p65 were up-regulated (P<0.05,P<0.01). Compared with the Portulacae Herba + inhibitor group, the high-dose Portulacae Herba cream group had a decreased skin lesion score (P<0.01), alleviated pathological damage to skin tissue, decreased content of IL-1β, IL-6, ROS, and MDA in the serum of mice (P<0.05,P<0.01), and increased content of SOD (P<0.01). The protein expression levels of Nrf2, HO-1, and IκBα and the mRNA expression of Nrf2 and HO-1 in skin tissue were up-regulated (P<0.05,P<0.01), and the protein expression levels of p-IκBα and p-NF-κB p65 and the mRNA expression of NF-κB p65 were down-regulated (P<0.05). ConclusionPortulacae Herba can improve DNCB-induced ACD skin damage in mice by regulating the Nrf2/HO-1/NF-κB signaling pathway.

【Objective】 To explore the surgical treatments and therapeutic outcomes for benign testicular tumor. 【Methods】 Clinical data of 53 patients with benign testicular tumor treated with surgery during May 2004 and Jul.2021 were retrospectively analyzed. 【Results】 The postoperative pathological diagnosis of 53 patients included 33 patients with epidermal cysts, 12 with mature teratomas, 2 with bilateral testicular tumors (one of them was epidermal cysts in the left and mature teratoma in the right, and the other was bilateral leiomyomas), and 6 benign cases. Testis sparing surgery (TSS) group had 23 patients and radical orchiectomy (RO) group had 30 patients. There were no significant differences in patients’ age, tumor location, disease course, and ultrasound examination results between the two groups (P>0.05). The tumor size of the RO group was (2.60±0.94) cm, which was larger than that of the TSS group (1.55±0.52) cm (P<0.001). There were no statistically significant differences in surgical time and postoperative hospital stay between the two groups (P>0.05). A total of 15 patients (13 with TSS and 2 with RO) underwent intraoperative frozen rapid pathological examination (FSA), which was consistent with post-operative paraffin pathological results. Durign the follow up of 2-219 months,median 38 months, there was no recurrence in either groups. 【Conclusion】 Testis sparing surgery is a reliable treatment modality for benign testicular tumor, which may also decrease the level of androgen and incidence of asthenozoospermia. It can be considered for tumors less than 2 cm with benign tendency or uncertain nature.
