OBJECTIVE: To investigate the efficacy and safety of Yisui Shengxue Granule (YSSXG), a compound traditional Chinese herbal medicine, in treating beta-thalassemia. METHODS: A randomized single-blinded trial was designed. Sixty patients with beta-thalassemia were divided into two groups: 30 patients in YSSXG-treated group and 30 in placebo parallel-control group. The patients in the two groups were assigned to receive either YSSXG or placebo for three months. The patients' symptoms and their blood indexes such as hemoglobin (Hb), red blood cell (RBC), reticulocytes (Ret) and fetal hemoglobin (HBF) were examined before and after the treatment. Meanwhile, the liver and spleen were examined with B-mode ultrasound. RESULTS: In the YSSXG-treated group, the blood indexes (Hb, RBC, Ret and HBF) and the symptoms of the patients were improved after three-month treatment, with statistical significance compared to those before treatment (P<0.01); hepatauxe and splenomegaly were also relieved (P<0.05) and no adverse reactions were monitored. In the placebo parallel-control group, no significant improvement of the blood indexes and symptoms, as well as the hepatauxe and splenomegaly had been found (P>0.05). CONCLUSION: YSSXG demonstrates obvious clinical efficacy and no adverse reactions in treating beta-thalassemia.

Objective To explore the ultrasonographic features ,diagnostic clues and methods of fetal aortic arch anomalies ,and to improve the diagnosis rate of prenatal ultrasonography for fetal aortic arch anomalies . Methods Fetuses with aortic arch anomalies diagnosed by prenatal ultrasound were selected as the study objects . The prenatal ultrasonographic features of the three views of the aortic arch were carefully observed . The three views included the followings :the transverse view ( the view of three vessels and trachea) ,the sagittal view ( the longitudinal view of the aortic arch) ,and the coronal view ( the coronal view of the descending aorta) . The prenatal diagnostic clues and diagnostic techniques of aortic arch anomalies were summarized and analyzed . Results Eighty-one cases with aortic arch anomalies were followed up . Fifteen cases were left-sided aortic arch and left-sided ductus arteriosus with aberrant right subclavian artery ,22 cases with right aortic arch and left-sided ductus arteriosus with aberrant left subclavian artery ,4 cases were mirror right aortic arch and left-sided ductus arteriosus ,2 cases were mirror right aortic arch and right-sided ductus arteriosus ,11 cases were double aortic arch ,23 cases were coarctation of the aorta ,and 4 cases were interruption of aortic arch . Among them ,27 cases were complicated with other cardiac and extra-cardiac malformations and 13 cases with chromosomal abnormalities . Prenatal ultrasonographic clues for diagnosis of coarctation of the aorta included the three vessels and trachea view showing small diameter and disproportion to the diameter of the ductus arteriosus . And the longitudinal view of the aortic arch was helpful for showing the position and the extent of coarctation of the aorta . Prenatal ultrasonographic clues for diagnosis of interruption of aortic arch were that the three vessels and trachea view and the longitudinal view of the aortic arch showed the interruption between aortic arch and descending aorta . And the abnormal combination cases of the aortic arch segments also had their corresponding diagnostic clues . These clues included that the three vessels and trachea view showed abnormal position ,arrangement and running of the branches of the aortic arch . And the coronal view of the descending aorta also showed abnormal changes in the branches of aortic arch . Conclusions Various types of congenital aortic arch anomalies have characteristic ultrasonography and their corresponding diagnostic clues and methods . The combined use of the three views of the aortic arch is effective in prenatal diagnosis for aortic arch anomalies .

CD3⁺ (1 087.34/μl ± 432.19/μl vs. 918.27/μl ± 199.72/μl, t=2.511), CD4⁺ (738.16/μl ± 326.75/μl vs. 588.43/μl ± 212.55/μl, t=2.716) and CD4/CD8 (1.87 ± 0.56 vs. 1.16 ± 0.55), t=6.483) were significantly higher than those of the control group (P<0.05); CD8⁺ (788.32/μl ± 214.56/μl vs. 976.37/μl ± 318.62/μl, t=3.462) was significantly lower than that of the control group (P<0.05). Conclusions Heshi-Gejiugao can reduce the symptoms and improve the quality of life by regulating the multi target and multi direction of the neuroendocrine immune network of perimenopausal patients.

Objective: To analyze the plague monitoring results in Ulanqab City of Inner Mongolia in 2018, to master the changes in rat density and the prevalence of plague in rats, and provide a basis for scientific prevention and control of plague. Methods: According to "The Plague Monitoring Scheme of Inner Mongolia", we surveyed Siziwang Banner, Chahar Right Back Banner, Huade County, and Shangdu County of Ulanqab City from April to November 2018 to monitor the plague. Rat density was surveyed using a one-day bow clamp method; small rodent was surveyed using a 5 m clamping method. Rodents were obtained by sample method, 5 m clamping method, daily method, collecting dead animals and the like, and fleas were picked up from the captured rats and rat nest. The rodents and fleas were carried out pathogen detection, the serum of rodents was tested by indirect hemagglutination test. Laboratory test results were analyzed based on the "Diagnostic Criteria for Plague" (WS 279-2008). Results: Totally 1 463 mice were captured overlapping a monitored area of 416 hm², the average rat density was 3.52 per hectare; the number of Meriones unguiculatus was 1 235, and the rat density was 2.97 per hectare. Totally 1 603 mice were grooming, 404 mice with fleas, the flea infected rate was 25.20%, the number of fleas were 1 348, and the flea index was 0.84. A total of 22 mouse nests were dug, 17 nests with fleas, the flea infected rate was 77.27%, the number of fleas were 131, and the flea index was 5.95. Totally 1 603 rodents were checked by etiology, the results showed that 7 plague rats were all Meriones unguiculatus. Totally 1 479 fleas of 581 groups were cultured, 14 fleas of 5 groups were detected, 3 fleas of 1 group in Siziwang Banner, and 11 fleas of 4 groups in Huade County. Totally 243 samples of murine animal serum were tested and the results were all negative. Conclusions The epidemic of plague in Ulanqab City is in an active state, so monitoring should be strengthened in this area to prevent the prevalence of human plague.
