The rat c-erbA? cDNA fragment was used as probe to investigate the expression of T3 receptor gene in brain, heart and kidney in hyperthyroid and hypothyroid rats. There were three types of c-erbA? mRNA-6. 0kb, -5. 0kb and -2. 0kb in all examined tissues. In heart and kidney, the levels of c-erbA? mRNA decreased in hyperthyroid rats and increased in hypothyroid rats. It might be a compensatory mechanism. In brain, however, the level of c-erbA? mRNA was unaffected by thyroid status. The results suggest that the T3 receptor gene may have an auto-regulatory mechanism in rat heart and kidney under different thyroid status.

Objective To investigate the application effect of pelvic rocking with balloon bionic midwifery in head dystocia. Methods Prospective research method was selected, and 400 pregnant women with head dystocia were divided into 2 groups by random digits table method with 200 cases each. The observation group was given pelvic rocking with balloon bionic midwifery delivery, and the control group was given gauge and comfortable posture with manual rotation fetal head delivery. The labor stage and delivery outcome were observed in two groups. Results The rate of successfully correct the fetal position was 91.00%(182/200) in observation group and 65.00%(130/200) in control group,and there was significant difference between 2 groups, χ2=39.394,P<0.01. The cesarean section rate was 7.00%(14/200) in observation group and 27.00%(54/200) in control group,and there was significant difference between 2 groups, χ2=113.119,P<0.01. The first, second and total labor stage were (8.86 ±2.20), (0.72 ±0.52), (9.78 ±2.82) h in observation group and (12.60±2.10), (1.02±0.82), (13.83±3.01) h in control group, and there were significant differences between 2 groups, t=15.684,4.058,12.609, P<0.01. The incidence of episiotomy, perineal laceration of Ⅱ degree, fetal distress, neonatal asphyxia and postpartum hemorrhage were 17.20%(32/186), 6.45%(12/186), 1.00%(2/200), 0, (150.80 ±43.54) ml in observation group, and 42.47%(62/146), 41.48%(61/146), 9.00%(18/200), 3.00%(6/200), (254.60±83.50) ml, and there were significant differences between 2 groups, P <0.01 or 0.05. Conclusions Pelvic rocking with balloon bionic midwifery can effectively correct the fetal position, reduce head dystocia and cesarean section rate, shorten the first labor stage, the second labor stage, reduce the occurrence of complication of mother and infant.

Objective Based on the result of evaluating the nutritional state of in-patients using the methodologies of European Nutritional Risk Screening 2002(NRS 2002),we judged the rationality of nutritional therapy,and the rate of accepting nutritional therapy in hospital patients.Methods Totally 3567 inpatients consisted with the requirement of NRS2002 were investigated nutritional state and the situation of nutritional therapy within 2 weeks in hospital.Except BMI used as the standard of China,all the other methods were from NRS2002.Nutritional therapy included parenteral and enteral nutrition.Results In all objects,834 patients' number score was≥3(23.39%),and 256 got nutritional therapy among them(30.70%).The number of accepting nutritional therapy was 661(18.53%),and only 38.73% of them had a patient number score≥3.Conclusion NRS2002 is a good method to evaluate the nutritional state of in patients.The nutritional therapy should be on the basis of patient's nutritional state,but there isn't one specification in clinical nutrition-support.Many malnourished patients were ignored,while a lot of nutritional therapies were not suitable.Now one of method to solve this question is to set up Nutrition Support Team(NST).

An elderly female patient was admitted to Shenzhen Traditional Chinese Medicine Hospital on May 4, 2023, due to recurrent cough for 4 years and aggravation with fever for 6 days. Chest CT showed bronchiectasis with pulmonary infection. Sputum smear microscopy indicated the possibility of Nocardia, and sputum fungal culture revealed Aspergillus fumigatus. After several days of anti- Nocardia and anti- Aspergillus fumigatus treatment, the patient′s inflammatory index decreased but she still had a low-grade fever. Effective communication between the laboratory and clinicians facilitated the culture of bronchoalveolar lavage fluid and the detection of metagenomic next-generation sequencing. The patient made progress after receiving anti-infection treatment for three suspected pathogenic bacteria- Nocardia amamiensis, Mycobacterium tuberculosis, and Aspergillus fumigatus-detected by the above methods. For the diagnosis of coinfection, the combination of multiple methods can improve the accuracy of pathogen identification, thereby better guiding clinical treatment.
