OBJECTIVE To clarify the weight index and optimize the technology of compound Mingmu Yijing pills. METHODS Water content, dissolution time limit and bolus-forming pass rate were included as evaluation indexes. The analytic hierarchy process(AHP) and the criterion importance through inter-criteria correlation(CRITIC) method based on the objectivity of indicators were adopted, AHP-CRITIC mixed weighting method. In this way, the relative coefficients of each index were calculated for weight distribution and comprehensive score, and the molding process was optimized and verified by Box-Behnken response surface test. RESULTS Compared with the single weighting method, the AHP-CRITIC mixed weighting method was more reasonable and stable. This method finally optimized the forming process conditions of Mingmu Yijing pills as follows: adding water amount of 0.8 times, the damp mass infiltration for 0.5 h, drying temperature of 60 ℃, drying time of 8 h. The mean comprehensive score of validation experiment was 88.21, RSD was 0.29%. CONCLUSION AHP-CRITIC method scientifically determines the weight of multiple indicators, and the verification test confirms that the optimized molding process is stable and feasible, which can be used in practical large-scale production.

Objective:To investigate the factors influencing the success of external cephalic version.Methods:Pregnant women who underwent an external cephalic version due to breech or transverse presentation by the same operator in the Third Affiliated Hospital of Zhengzhou University from July 2015 to July 2021 were selected as the study objects. Univariate analysis and logistic regression analysis were used to explore the clinical factors influencing the success of the external cephalic version. The receiver operating characteristic (ROC) curve was used to analyze the best cut-off value of gestational week and amniotic fluid index at the time of operation and to evaluate the predictive value of the influencing factors on the success of the external cephalic version.Results:(1) A total of 118 cases finally entered this study. Among the 118 cases,77 cases (65.3%) succeeded in the external cephalic version, among which the success rate was 49.1% (27/55) for primipara and 79.4% (50/63) for multipara. The vaginal delivery rate was 56.8% (67/118). (2) Complications occurred in 19 (16.1%) of the 118 cases. The main complications were abnormal fetal heart rate (13 cases, 11.0%), umbilical cord presentation, and fetal position reversion (two cases and 1.7% in each), and the serious complications were intrauterine fetal death and placental abruption (one case and 0.8% in each).The complication rate of patients with successful external cephalic version was 7.8% (6/77), which was lower than that of those who failed the external cephalic version [31.7%(13/41)] ( χ 2=11.33, P=0.001). (3) Multivariate analysis showed that gestational week at surgery before 38, amniotic fluid index >11.10 cm, and multipara were the factors affecting the success of the external cephalic version [ OR(95% CI)=0.561(0.351-0.897), 1.173(1.018-1.351) and 4.201(1.547-11.404), all P<0.05]. (4) The area under the ROC curve of the combination of the gestational week at surgery, amniotic fluid index, and parity was 0.744 (95% CI: 0.640-0.848, P<0.001), and the Youden index was 0.518, with a sensitivity of 70.0% and a specificity of 81.8%. Conclusion:Gestational weeks, amniotic fluid index, and multipara are related to the success of the external cephalic version, and the combination of the three has certain predictive power for the success of the surgery.

We report a case of a pregnant woman with 46,XX karyotype and positive sex-determining region on the Y chromosome ( SRY) gene and her female fetus. Ultrasound examination at 12 +6 gestational weeks indicated a thickened fetal nuchal translucency, and 46, XX with a positive SRY gene was detected in the fetus through quantitative fluorescent-polymerase chain reaction and amniotic fluid karyotype. However, the ultrasound showed that the gender of the fetus was female, which was inconsistent with the phenotype of male syndrome with 46, XX combining positive SRY gene. The fluorescent in situ hybridization (FISH) revealed that the short arm of the Y chromosome translocated to the long arm of one of the X chromosomes, namely Yp11.3-Xq28. In addition, a copy number variation at Yp11.31p11.2 copy (about 1 MB) was found by chromosomal microarray analysis, which validated the result of FISH and was consistent with the mother. After genetic counseling, the parents chose to continue the pregnancy to full term, and no abnormalities were found in the infant during the follow-up.

OBJECTIVE： To study the effects of cimetidine on low dose rate irradiation-induced liver cell apoptosis in Beagle dogs. METHODS： Healthy male Beagle dogs were randomly divided into normal control group， model control group， positive drug group （lentinan， 21.33 mg/kg） and cimetidine low-dose， medium-dose and high-dose groups （5.33， 10.67， 21.33 mg/kg）， with 4 Beagle dogs each. Except for normal control group， other groups were given 60Co-γ accumulative irradiation （dosage rate： 0.040 8 mGy/min） for 23 d； the medication groups were given relevant medicine orally before irradiation， once a day. Twenty-four hours after stopping irradiation， TUNEL method was used to detect the apoptosis of liver cells in Beagle dogs. The percentage of apoptotic cells was calculated. The expression level of apoptosis-related proteins （Bax， Bcl-2， Caspase-3， p53） in liver tissue was detected by immunohistochemistry. RESULTS： Compared with normal control group， apoptotic cells and Bax， Caspase-3， p53 positive cells were increased significantly in liver tissue of Beagle dogs in model control group； the percentage of apoptotic cells， protein expression levels of Bax， Caspase-3 and p53 were increased significantly； Bcl-2 positive cells were decreased significantly， and its protein expression level was decreased significantly （P＜0.05 or P＜0.01）. Compared with model control group， above positive cells of liver tissue in Beagle dogs were changed to different extents in medication groups； the percentage of apoptotic cells and protein expression levels of p53 in medication groups， protein expression levels of Bax in positive drug group， cimetidine low-dose and high-dose groups as well as protein expression levels of Caspase-3 in cimetidine groups were decreased significantly； protein expression levels of Bcl-2 were increased significantly in cimetidine groups. The percentage of apoptotic cells in cimetidine medium-dose and high-dose groups as well as protein expression levels of Caspase-3 in cimetidine groups were all lower than positive control group. Protein expression level of p53 in cimetidine low-dose group was significantly higher than positive drug group （P＜0.05 or P＜0.01）. CONCLUSIONS： Cimetidine can inhibit the low dose rate irradiation-induced apoptosis of liver cells in Beagle dogs， and certainly protect liver cells against irradiation. The mechanism of it may be associated with up-regulating the protein expression of Bcl-2 and down-regulating the protein expression of Bax， Caspase-3 and p53 in liver cells.
