Purpose To study the clinicopathological and immunohistochemical features, carcinogenesis and differential diagnosis of female pelvic serous carcinoma. Methods The clinical data, macroscopic and microscopic features and immunostaining results of 20 patients with pelvic serous carcinoma were studied, and some associated literatures were reviewed. Results 20 cases of PSC aged from 23 to 87, with the mean age being 58. 9. PSC may occur in fallopian tube, ovary and peritoneum, while they were referred to hospital because of abdominal distention, abdominal pain or pelvic mass. The tumor often invasive pelvic organs diffusely when they were diag-nosed, so, the primary site were difficultly determined. Usually, the primary focus of serous carcinoma of fallopian tube is small and easily planted in pelvic. The patients with ovarian serous carcinoma or peritoneal serous carcinoma had serous tubal intraepithelial car-cinoma at the mean time. Conclusions The tubal epithelial cells may be the major source of PSC. About the specimen of PSC, we need check the fallopian tube carefully to determine the primary site, and make differential diagnosis with peritoneal malignant mesothe-lioma and metastatic carcinoma from other sites than pelvic when it diffusely invasive peritoneum.

Objective To investigate the clinical therapeutic effect of citicoline sodium combined with Shenxiong glucose in the treatment of senile hypertensive cerebral infarction in the elders.Methods 80 elderly patients with senile hypertensive cerebral infarctiontreated in our hospital were selected and randomly divided into the single treatment group and the combination treatment group,40 cases in each group.Both groups received the routine treatment.The single treatment group additionally received Shenxiong glucose injection (100 ml/d),while patients in the combination treatment group additionally received Shenqiong glucose injection combined with citicoline sodium intravenous infusion therapy (0.5 g/d),both groups were treated for 2 weeks.The levels of serum inflammatory factors,the neurological deficit score,the cognitive function score were compared and analyzed before and after treatment between two groups.Results After systemic treatment,the blood pressure and blood lipid levels of two groups were significantly improved,but there was no significant difference between the two groups (P ＞ 0.05);The serum levels of interleukin (IL)-6,IL-8 and tumor necrosis factor-α (TNF-α) of the combination treatment group improved more significantly (P ≤0.05).After treatment,the oxidative stress indexes were significantly improved in the two groups (P ≤ 0.05).The content of malondialdehyde (MDA) was decreased,while the superoxide dismutase (SOD) activity and nitric oxide (NO) content were increased significantly (P ≤ 0.05);and the improvement degree in the combination treatment group was better than in the single treatment group (P ≤0.05).The degree of improvement in the Modified Edinburgh-Scandinavia Stroke Scale (MESSS) and Hasegawa Dementia Scale (HDS) scores of the combination treatment group was more significant than those in the single treatment group (P ≤ 0.05).The total effective rate of the combination treatment group was 92.5％,which was significantly higher than that of the single group (75.0％),with statistically significant difference (P ≤ 0.05).No obvious adverse reactions happened in two groups during treatment.Conclusions Combination of citicoline sodium and shenxiang glucose on the basis of routine treatment can significantly reduce oxidative stress and inflammation levels,promote the recovery of neurological and cognitive functions,and improve the clinical efficacy and safety.It is worth popularizing and applying in the clinical treatment of senile hypertensive cerebral infarction.

Objective To assess the risk of human Spirometra mansoni infections and investigate the knowledge, attitude and practice (KAP) towards sparganosis mansoni among residents in Henan Province, so as to provide insights into formulation of the sparganosis mansoni control measures. Methods Qinling Village in Fugou County of Zhoukou City, Bali Village in Yancheng District of Luohe City, Duzhai Village in Puyang County of Puyang City and Doushan Village in Luoshan County of Xinyang City were sampled as survey sites in Henan Province from July to August 2023, and more than 40 frogs were sampled from ponds or streams in each survey site for detection of Sparganum mansoni infections. At least 150 residents were sampled using a cluster sampling method from each survey site, and the sero-prevalence of anti-S. mansoni IgG antibody was estimated. In addition, a questionnaire survey was conducted on the KAP towards sparganosis mansoni among participants, and the proportion of eligible KAP, rate of correct KAP and KAP scores were calculated. Results A total 229 frogs were collected from 4 survey sites in 2023, and the overall prevalence of S. mansoni infection was 4.37% (10/229) in frogs, with 7.75% (10/129) prevalence in wild frogs and 0 in farm-bred frogs. A questionnaire survey was performed among 649 residents sampled from 4 survey sites, and 649 serum samples were collected. The seroprevalence of anti-S.mansoni IgG antibody was 0.15% (1/649) and the overall proportion of eligible KAP was 23.73% (154/649) among participants. There were age- (χ² = 30.905, P = 0.000), educational level- (χ² = 41.011, P = 0.000), and occupation-specific proportions of eligible KAP among participants (χ² = 10.721, P = 0.005), and the proportion of eligible KAP decreased with age (χ² _trend = 22.717, P = 0.000) and increased with education levels (χ² _trend = 40.025, P = 0.000). The rates of correct KAP towards sparganosis mansoni were 40.81% (2 119/5 192), 96.66% (1 882/1 947) and 63.81% (3 727/5 841) (χ² = 1 913.731, P = 0.000) among residents, respectively. The rates of correct KAP towards sparganosis mansoni varied significantly among survey sites (χ² = 136.872, 42.347 and 255.157; all P values= 0.000, with the highest rate of correct knowledge (51.94%, 748/1 440) and practices (75.86%, 1 229/1 620) in Yancheng District of Luohe City and the highest rate of correct attitudes in Puyang County of Puyang City (99.11%, 446/450) (all P values< 0.05). Conclusions There is still a high transmission risk of sparganosis mansoni in Henan Province, and the KAP towards sparganosis mansoni is required to be improved among residents.
