ObjectiveMyelodysplastic syndromes （MDS） is a group of clonal hematopoietic stem cell disorders，and this study aims to investigate the expression of hypoxia-inducible factor-1α（HIF-1α） in the bone marrow cells of patients with MDS and its correlation with the clinical features of MDS，the therapeutic efficacy of arsenic-containing Chineseherbal compound，and the survival prognosis. MethodAccording to the inclusion and exclusion criteria，27 MDS patients treated with arsenic-containing Chinese herbal compound in the Department of Hematology，Xiyuan Hospital，China Academy of Chinese Medical Sciences from January 2022 to September 2022 were included，and their bone marrow samples were collected by myelotomy. HIF-1α expression level in bone marrow cells was detected by real-time polymerase chain reaction （PCR） to analyze its correlation with clinical features，and logistic and Cox regression was used to analyze the risk factors affecting the efficacy and prognostic survival of MDS patients. ResultThe HIF-1α mRNA expression level was lower in bone marrow cells of MDS patients than in healthy subjects. HIF-1α was positively correlated with the degree of myelodysplasia（r=0.384，P<0.05） and bone marrow granulocytic system%（G%）（r=0.560，P<0.01）. Logistic regression showed that HIF-1α was a risk factor for the prognosis in the follow-up of the efficacy of treatment（P<0.05）and Cox regression showed that HIF-1α was an independent factor affecting the survival prognosis of MDS patients ［odds ratio（OR）=398.968，95% confidence interval（CI）（1.281，116 858.743），P<0.05］. ConclusionThe level of HIF-1α expression in bone marrow cells of MDS patients was closely related to the degree of clinical myelodysplasia and G%，and HIF-1α was a risk factor for the efficacy for and survival prognosis of MDS patients.

Objective:To examine the associations of pre-pregnancy body mass index (BMI), gestational weight gain, and gestational diabetes mellitus (GDM) with early childhood BMI trajectories.Methods:A total of 1 227 mother-child pairs from the Peking University Birth Cohort in Tongzhou were included in this study. In the cohort, maternal pre-pregnancy weight, height, gestational weight gain, and GDM diagnosis were collected. The children were followed up at birth and at 1, 3, 6, 9, 12, 18, 24, 30, and 36 months of age to obtain height/length and weight data. The longitudinal data-based k-means clustering algorithm was used to identify early childhood BMI trajectory groups. The associations of maternal pre-pregnancy BMI, gestational weight gain, and GDM with early childhood BMI trajectories were analyzed using the logistic regression model. We further explored whether there is an interaction effect between pre-pregnancy overweight/obesity and excessive gestational weight gain on the risk of the high BMI trajectory in early childhood through multiplicative and additive interaction analyses. Results:The prevalence rates of overweight and obesity before pregnancy were 21.2% (260 cases) and 6.6% (81 cases) respectively. The prevalence of excessive gestational weight gain and GDM was 57.7% (708 cases) and 30.9% (379 cases). The early childhood BMI trajectories were named low, medium, and high trajectories, accounting for 30.5%, 45.4% and 24.1%, respectively. After controlling potential confounding factors, it was found that pre-pregnancy overweight ( OR=1.54, 95% CI: 1.12-2.12), obesity ( OR=2.33, 95% CI: 1.41-3.85), and excessive gestational weight gain ( OR=1.47, 95% CI: 1.10-1.97) were risk factors for being in the high BMI trajectory in early childhood. GDM was not significantly associated with early childhood BMI trajectories ( P>0.05). Compared with the independent effects of pre-pregnancy overweight/obesity ( OR=1.90, 95% CI: 1.17-3.09) and excessive gestational weight gain ( OR=1.45, 95% CI: 1.03-2.04), the risk of being in the high BMI trajectory in early childhood was greater when the two factors coexisted ( OR=2.38, 95% CI: 1.60-3.54). However, both the multiplicative and additive models showed no interaction effect between pre-pregnancy overweight/obesity and excessive gestational weight gain. Conclusions:Maternal pre-pregnancy overweight/obesity and excessive gestational weight gain are independent risk factors for children being in the high BMI trajectory in early childhood, providing scientific evidence for obesity prevention.

[Objective]To explore the inheritance status and academic characteristics of SHI's acupuncture and moxibustion school in northern Zhejiang,and to further enrich the connotation of Xiushui medical school.[Methods]Using the method of reviewing and researching the traditional medical history literature and modern literature,the origin,inheritance and academic characteristics of SHI's acupuncture and moxibustion were excavated,analyzed and sorted out.[Results]The culture of traditional Chinese medicine in northern Zhejiang is profound,there are many genres of acupuncture and moxibustion,and many famous doctors and scholars.The more influential schools of acupuncture and moxibustion are LING,SHI,YAN,SHENG and JIN,which have been passed down from generation to generation and innovated repeatedly.As one of the typical representatives,SHI's acupuncture has a long history,active inheritance and rich content.In clinical practice,great importance is attached to the spleen and stomach,and the treatment principle is to strengthen the spleen and benefit the stomach,warm and transport Yang Qi of middle-Jiao,and be good at applying warm acupuncture,so that Qi can be warmed and operated easier,and the acupuncture can be helped to regulate Qi.SHI's acupuncture also pays attention to the combination of acupuncture and moxibustion,and the combination of acupuncture and medicine to improve clinical efficacy.SHI's descendants are constantly innovating while inheriting and keeping the right,so as to enrich the disease spectrum,enrich the treatment methods and improve the clinical efficacy.[Conclusion]In the process of continuous inheritance and innovation,SHI's acupuncture has gradually formed a diagnosis and treatment system with acupuncture characteristics in northern Zhejiang,which can provide learning and reference for clinical practice.

Acute high altitude disease (AHAD) is a general term for a series of clinical reactions that occur when the body fails to adapt to the low-pressure hypoxic environment of high altitudes. Mild cases can cause symptoms such as headache, nausea and vomiting, while more severe cases can lead to life-threatening conditions such as pulmonary edema, cerebral edema and other critical conditions that can be fatal. With the increasing demand for high altitudes deployment, understanding the common preventive measures of AHAD can reduce its morbidity or mortality to a certain extent, which is of great benefit to those who reside temporarily at high altitudes. In recent years, as people's health awareness has improved, there has been a growing attention towards non-pharmacological methods of disease prevention. At the same time, non-pharmacological therapy has significant therapeutic effects in preventing and treating high-altitude diseases, which has attracted the attention of researchers in this field. This review summarizes the major non-pharmacological preventive components of modern medicine and outlines the current non-pharmacological approaches to AHAD from the perspective of traditional Chinese medicine, intending to serve clinical purposes and improve the onset and prognosis of AHAD.

Objective:To construct a physical restraint reduction scheme based on eCASH concept (that is early Comfort using Analgesia, minimal Sedatives and maximal Human care for adult patients after cardiac surgery, and intervene, and to evaluate its effectiveness.Methods:A non-synchronous case-control study was conducted. A total of 486 patients after cardiac surgery admitted to the cardiac surgery intensive care Unit (ICU) of Shandong Provincial Hospital Affiliated to Shandong First Medical University from July to October 2022 were enrolled as subjects. According to the implementation time node of the physical restraint reduction scheme, 250 patients admitted from July to August were served as the control group, and 236 patients admitted from September to October were served as the observation group. The control group adopted the routine physical restraint nursing process, including selecting the appropriate restraint device according to the patient's condition and consciousness and following the doctor's advice, and checking on time to prevent adverse reactions. The observation group implemented the physical restraint reduction scheme based on eCASH concept, including preoperative visit, postoperative assessment of whether patients needed physical restraint according to the restraint decision wheel and the physical restraint flow, and adopted personalized nursing programs. The restraint rate, restraint duration, incidence of restraint-related complication (edema of the limbs, redness and swelling of the skin in the restricted area, skin rupture, etc.), restraint device application standard rate, delirium rate and incidence of unplanned extubation event were compared between the two groups.Results:There was no significant difference in age, gender, cardiopulmonary bypass, endotracheal catheter retention duration and operation type between the two groups with comparability. The restraint rate in the observation group was significantly lower than that in the control group [16.95% (40/236) vs. 84.40% (211/250), P < 0.01], and the restraint duration was significantly shorter than that in the control group [hours: 0 (0, 1.0) vs. 7.0 (5.5, 10.0), P < 0.01], the incidence of restraint-related complication and delirium were significantly lower than those in the control group [restraint-related complication: 0.85% (2/236) vs. 1.60% (4/250), delirium: 0% (0/236) vs. 2.80% (7/250), both P < 0.05], and the restraint device application standard rate was significantly higher than that in the control group [100.00% (40/40) vs. 90.52% (191/211), P < 0.05]. No unplanned extubation event occurred in both groups. Conclusion:The physical restraint reduction scheme based on eCASH concept in adult patients after cardiac surgery can effectively reduce the restraint rate and the incidence of restraint-related complication, shorten the restraint duration, reduce the incidence of delirium, improve the standardization of restraint device application, without increasing the incidence of unplanned extubation events.

Objective To observe the value of three-dimensional ultrasound virtual organ computer-aided analysis(VOCAL)technique for measuring choroid plexus volume(CPV)and lateral ventricle volume(LVV)in normal fetus of 11-13+6 gestational weeks.Methods Three-dimensional ultrasonic data of 428 normal singletons at 11-13+6 gestational weeks were retrospectively analyzed.The fetuses were divided into 11-11+6 weeks group(n=77),12-12+6 weeks group(n=225)and 13-13+6 weeks group(n=126).Fetal CPV,LVV and CPV/LVV ratio were measured and calculated using VOCAL technique and compared between groups.Pearson correlation analysis was performed to observe the correlations of CPV,LVV,CPV/LVV ratio with crown-rump length(CRL).Results Significant differences of CPV,LVV and CPV/LVV ratio were found among groups(all P＜0.05).Among 11-11+6 weeks group,12-12+6 weeks group and 13-13+6 weeks group,CPV and LVV increased progressively,while CPV/LVV ratio decreased progressively(all adjusted P＜0.05).During 11-13+6 gestational weeks,CPV and LVV were both highly positively correlated with CRL(r=0.904,0.929,both P＜0.05),while CPV/LVV ratio was highly negatively correlated with CRL(r=-0.893,P＜0.05).Conclusion Three-dimensional ultrasound VOCAL technique was feasible for measuring CPV and LVV in normal fetus of 11-13+6 gestational weeks.

Objective:To explore the effectiveness and safety of endoscopic ultrasound-guided pancreatic duct drainage (EUS-PD).Methods:A retrospective analysis was conducted on data of 16 patients who underwent EUS-PD because of endoscopic retrograde pancreatography (ERP) failure, poor effectiveness or anatomical changes and couldn't undergo the routine ERP in Nanjing Drum Tower Hospital from June 2018 to July 2022. The technical success of EUS-PD, clinical efficacy and post-procedure adverse events were analyzed.Results:In the 16 patients, there were 14 males and 2 females, with age of 50.69±12.95 years. A total of 19 times of EUS-PD operations were included, 3 of them were rendezvous-assisted endoscopic retrograde pancreatography (RV-ERP), 15 transgastric or transenteric EUS-guided stent placement and 1 was EUS-guided nasopancreatic duct placement. Technical success was achieved in 84.21% (16/19) patients, and among whom 93.75% (15/16) achieved clinical success. The overall incidence of postoperative adverse events was 52.63% (10/19) including 47.37% (9/19) abdominal pain, 15.79% (3/19) fever and 15.79% (3/19) postoperative pancreatitis. All adverse effects were relieved after general conservative treatment and no primary disease or surgery-related death occurred. The mean follow-up was 17.6 (8.2,22.3) months and 93.75% (15/16) of the patients were followed up. By the time of follow-up, 76.92% (10/13) of the patients who had successfully received EUS-PD had no recurrence of abdominal pain or distension.Conclusion:EUS-PD is a safe and effective alternative therapy for those with pancreatic diseases with ERP failure, poor efficacy or anatomical changes.

Objective:To evaluate the effects of hemoclips on preventing delayed bleeding for early gastric cancer (EGC) after endoscopic submucosal dissection (ESD).Methods:Clinical data of 459 patients who underwent ESD for EGC in Beijing Friendship Hospital from June 2013 to August 2020 were collected retrospectively. Patients were divided into group A (hemoclip group, n=162) and group B (non-hemoclip group, n=297) according to whether preventive hemostatic clip treatment was performed after resection. Delayed bleeding within 2 weeks after ESD was observed. Univariate analysis and subgroup analysis were conducted for the delayed bleeding incidence and clinicopathological features. Results:Delayed bleeding incidences of group A and group B were 3.1% (5/162) and 8.1% (24/297) with significant difference between the two groups ( χ2=4.418, P=0.036). Subgroup analysis showed that there were significant differences in the delayed bleeding incidence between the two groups when the diameter of the tumor >20 mm [3.5% (2/57) VS 15.3% (13/85), χ2=5.016, P=0.025], the tumor located in the lower part of the stomach [1.0% (1/97) VS 10.4% (20/192), χ2=8.425, P=0.004], and the depth of tumor invasion was M/SM1 [3.2% (5/157) VS 8.1% (23/285), χ2=4.072, P=0.044]. There were no significant differences in the delayed bleeding incidence between group A and group B when the diameter of the tumor ≤20 mm, the tumor located in the upper/medial part of the stomach and the depth of tumor invasion was SM2 ( P>0.05). Conclusion:Hemoclips can prevent delayed bleeding after ESD for EGC, which is mainly observed in a tumor of diameter >20 mm, located in the lower part of the stomach and M/SM1 tumor invasion. It has little effect on the prevention when the tumor diameter ≤20 mm and located in the upper/medial part of the stomach.
