Based on the"You Gu Wu Yun"theory in traditional Chinese medicine(TCM),this paper believes that"Gu"in"You Gu Wu Yun"is extended to"state"from the perspective of"TCM state".In order to avoid the adverse reactions of TCM,the macro,meso,and micro three views should be used together,and macro,meso,and micro parameters should be integrated.We should also carefully identify the physiological characteristics,pathological characteristics,constitution,syndrome,and disease of human body by combining qualitative and quantitative method,highlighting the relationship between the prescription and the"state".The correspondence between prescription and the"state"will reduce the risk of adverse reactions of TCM.In this paper,we hope to focus on the guiding role of the"You Gu Wu Yun"theory in TCM research,to give full play to the characteristics and advantages of TCM,and to dialectically treat the role of TCM.

To summarize the nursing experience of a pediatric patient who underwent hematopoietic stem cell transplantation following liver transplantation for erythropoietic protoporphyria,several key nursing points were identified.These included implementing plasma exchange to prevent liver failure,employing light-avoidance therapy to reduce photosensitivity,enhancing skin and mucosal care to minimize bacterial colonization,and strengthening caregiver management to prevent cross-infection.After hematopoietic stem cell transplantation,the main focus of nursing care shifted towards drug management to mitigate liver damage,closely monitoring the patient's condition for potential nervous system lesions,implementing effective diarrhea management strategies to prevent perianal infection,prioritizing psychological support in order to alleviate negative emotions experienced by the patient,and providing individualized health education and follow-up management plans aimed at promoting rehabilitation.Because of meticulous nursing provided by a dedicated multidisciplinary team,the child showed significant improvement within 34 days post-transplantation and continued recovering well during outpatient follow-up visits conducted 4 months after hospital discharge.

Objective:To learn about the epidemic situation and trend of human brucellosis in Menyuan Hui Autonomous County (referred to as Menyuan County) of Qinghai Province, and to provide reference for formulating brucellosis prevention and control measures in Menyuan County.Methods:Data on human brucellosis in Menyuan County reported by the Infectious Disease Reporting Information Management System of China Disease Control and Prevention Information System from 2013 to 2020 were collected and analyzed by descriptive epidemiological analysis (three distribution).Results:A total of 186 cases of brucellosis were confirmed from 2013 to 2020, with an average annual incidence of 14.553/100 000. The annual incidence rate was increasing year by year(χ 2trend = 22.08, P = 0.002). The cases were distributed in 67 villages of 12 towns; cases were more common in the age group of 15-< 65 years old (96.24%, 179/186), and there were more men than women cases (sex ratio was 3.89∶1.00, 148/38). Conclusions:The incidence rate of brucellosis cases in Menyuan County is increasing year by year, and the scope of its impact is constantly expanding. A multi-sectoral joint prevention and control mechanism should be established to strengthen management, increase the prevention and control of brucellosis, and stop the spread of the epidemic to surrounding counties and cities.

Objective:To explore the effect of fully automatic image segmentation of adenoid and nasopharyngeal airway by deep learning model based on U-Net network. Methods:From March 2021 to March 2022, 240 children underwent cone beam computed tomography（CBCT） in the Department of Otolaryngology, Head and Neck Surgery, General Hospital of Shenzhen University. 52 of them were selected for manual labeling of nasopharynx airway and adenoid, and then were trained and verified by the deep learning model. After applying the model to the remaining data, compare the differences between conventional two-dimensional indicators and deep learning three-dimensional indicators in 240 datasets. Results:For the 52 cases of modeling and training data sets, there was no significant difference between the prediction results of deep learning and the manual labeling results of doctors（P>0.05）. The model evaluation index of nasopharyngeal airway volume: Mean Intersection over Union（MIOU） s （86.32±0.54）%; Dice Similarity Coefficient（DSC）: （92.91±0.23）%; Accuracy: （95.92±0.25）%; Precision: （91.93±0.14）%; and the model evaluation index of Adenoid volume: MIOU: （86.28±0.61）%; DSC: （92.88±0.17）%; Accuracy: （95.90±0.29）%; Precision: （92.30±0.23）%. There was a positive correlation between the two-dimensional index A/N and the three-dimensional index AV/（AV+NAV） in 240 children of different age groups（P<0.05）, and the correlation coefficient of 9-13 years old was 0.74. Conclusion:The deep learning model based on U-Net network has a good effect on the automatic image segmentation of adenoid and nasopharynx airway, and has high application value. The model has a certain generalization ability.

To investigate the evaluation and management of gastrointestinal fistula after upper gastrointestinal tunnel endoscopic surgery, a retrospective analysis was performed on 15 patients with gastrointestinal fistula after upper gastrointestinal tunnel endoscopic surgery, who were treated at the Endoscopy Center of Zhongshan Hospital, Fudan University from January 2012 to October 2022. All patients were treated successfully after comprehensive treatment. Three patients received metal clipping and gastric tube drainage; 10 patients received gastric tube drainage combined with jejunal nutritional tube placement, and 7 of them had gastric tube directly put into the fistula cavity; 2 patients received covered esophageal stent placement combined with jejunal nutritional tube placement. Five patients received wound tissue glue spraying; 2 patients underwent purse-string suture with nylon loops and metal clips after reduced fistula burned by hot biopsy forcep or argon plasma coagulation. The gastrointestinal fistula after tunnel endoscopic surgery is a complex postoperative complication, which needs early detection, careful evaluation and comprehensive treatment.

Myostatin gene (MSTN) encodes a negative regulator for controlling skeletal muscle growth in animals. In this study, MSTN^-/- homozygous mutants with "double muscle" phenotypic traits and stable inheritance were bred on the basis of MSTN gene editing rabbits, with the aim to establish a method for breeding homozygous progeny from primary MSTN biallelic mutant rabbits. MSTN^-/- primary mutant rabbits were generated by CRISPR/Cas9 gene editing technology. The primary mutant rabbits were mated with wild type rabbits to produce F1 rabbits, whereas the F2 generation homozygous rabbits were bred by half-sibling mating or backcrossing with F1 generation rabbits of the same mutant strain. Sequence analysis of PCR products and its T vector cloning were used to screen homozygous rabbits. The MSTN mutant rabbits with 14-19 week-old were weighed and the difference of gluteus maximus tissue sections and muscle fiber cross-sectional area were calculated and analyzed. Five primary rabbits with MSTN gene mutation were obtained, among which three were used for homozygous breeding. A total of 15 homozygous rabbits (5 types of mutants) were obtained (M2-a: 3; M2-b: 2; M3-a: 2; M7-a: 6; M7-b: 2). The body weight of MSTN^-/- homozygous mutant rabbits aged 14-19 weeks were significantly higher than that of MSTN^+/+ wild-type rabbits of the same age ((2 718±120) g vs. (1 969±53) g, P < 0.01, a 38.0% increase). The mean cross sections of gluteus maximus muscle fiber in homozygous mutant rabbits were not only significantly higher than that of wild type rabbits ((3 512.2±439.2) μm² vs. (1 274.8±327.3) μm², P < 0.01), but also significantly higher than that of MSTN^+/- hemizygous rabbits ((3 512.2±439.2) μm² vs. (2 610.4±604.4) μm², P < 0.05). In summary, five homozygous mutants rabbits of MSTN^-/- gene were successfully bred, which showed a clear lean phenotype. The results showed that the primary breeds were non-chimeric mutant rabbits, and the mutant traits could be inherited from the offspring. MSTN^-/- homozygous mutant rabbits of F2 generation could be obtained from F1 hemizygous rabbits by inbreeding or backcrossing. The progenies of the primary biallelic mutant rabbits were separated into two single-allelic mutants, both of which showed a "double-muscle" phenotype. Thus, this study has made progress in breeding high-quality livestock breeds with gene editing technology.

To investigate the feasibility and safety of endoscopic trans-gastric cholecystolithotomy(ETGC) combined with endoscopic retrograde cholangiopancreatography (ERCP) for cholecystolithiasis and choledocholithiasis. Data of patients with cholecystolithiasis and choledocholithiasis who underwent ETGC after ERCP in Zhongshan Hospital Affiliated to Fudan University from November 2018 to April 2019 were analyzed. Six patients with cholecystolithiasis and choledocholithiasis, 4 males and 2 females, were included in this study.The interval between ERCP and ETGC ranged from 1 to 77 days (median 5 days). All the 6 patients successfully completed ETGC after ERCP, with a surgical success rate of 100%. All the patients had multiple cholecystolithiasis and one patient was complicated with gallbladder polyps.The ETGC operation time was 22-100 min (median 65 min), and the length of hospital stay was 3-9 d (median 6.5 d). Two patients had dull pain in the upper abdomen and increased body temperature after surgery. Abdominal ultrasound in one patient suggested local effusion in the right upper abdomen.Both patients improved after conservative treatment.None of the patients had cholecystitis and cholangitis related symptoms such as right upper abdominal pain or fever during postoperative follow-up, and the follow-up rate was 100%with median follow-up time of 18 month.All the 6 patients underwent abdominal ultrasound examination after surgery. No recurrence occurred in 5 patients. One of the patients showed cholesterol crystals in the gallbladder wall and bile mud deposition.ETGC combined with ERCP is safe and feasible for cholecystolithiasis and choledocholithiasis.
