Objective:To analyse the clinical characteristics of 214 cases of paediatric high altitude pulmonary edema（HAPE）and the efficacy of dexamethasone in adjunctive therapy.Methods:This retrospective study analyzed 214 pediatric cases of HAPE admitted to the Department of Paediatrics of the General Hospital of Tibetan Military between June 2015 to June 2017 and June 2019 to June 2021.Patients were divided into dexamethasone-treated group and dexamethasone-untreated group.Baseline data，clinical characteristics were collected to evaluate the treatment efficacy and drug side effects.Results:There were 107 children in each of the two groups with a median age of 8（5，11）years. The median age of the dexamethasone-treated group was 9（6，12）years and the mean age of the dexamethasone-untreated group was 7（3，10）years. The proportion of male children was 69.60%（149/214）；the onset of illness was mostly concentrated within 72 hours，accounting for 97.20%（208/214）of the cases；83.18%（178/214）of the cases had symptoms of combined upper respiratory tract infection before entering the plateau. The most important clinical symptoms of the children were cough（86.92%，186/214），cyanosis（70.09%，150/214），and shortness of breath（66.36%，142/214）. The proportion of auscultatory rhonchi was 83.18%（178/214），and all cases showed positive findings on chest radiography. After the dexamethasone regimen，the overall cure rate of the children was 94.39%，the average disappearance time of the symptoms and signs was（40.52±7.85）h，and the average hospital stay was（3.60±1.90）d. After treatment with the dexamethasone-free regimen，the overall cure rate was 92.52%，the mean time to disappearance of symptoms and signs was（42.10±7.62）h，and the mean length of stay in the hospital was(3.84±2.08)d. There was no significant difference in the cure rate，the disappearance time of symptoms and signs，and the average hospitalisation days between the two groups（ P>0.05），but a total of 11 children in the dexamethasone-treated group experienced adverse drug reactions，and no children in the dexamethasone-untreated group experienced adverse drug reactions. Conclusion:Han Chinese male children，particularly those with upper respiratory infections，should be closely monitored for HAPE risk within three days of ascending to high altitudes. This study does not recommend the use of dexamethasone for pediatric HAPE due to the lack of therapeutic benefits and potential adverse effects.

Objective To investigate the influencing factors associated with early neurological deterioration(END)in patients with minor acute ischemic stroke(mAIS),develop a clinical prediction model for END,and identify independent risk factors for 90-day neurological functional outcomes after stroke.Methods mAIS patients admitted consecutively to the Department of Neurology,Yijishan Hospital of Wannan Medical College(the First Affiliated Hospital of Wannan Medical College),from July 2023 to July 2024 were retrospectively collected.A minor ischemic stroke was defined as acute ischemic stroke with a National Institutes of Health stroke scale(NIHSS)score≤5 on admission.Baseline,clinical,and imaging data of all mAIS patients were collected and recorded,including demographic information(age,sex),past medical history(hypertension,diabetes mellitus,hyperlipidemia,coronary heart disease,atrial fibrillation),smoking history,alcohol consumption,baseline blood pressure,pre-onset modified Rankin scale(mRS),NIHSS scores at admission and during hospitalization(24 hours,48 hours,72 hours after admission),motor component subscore of the NIHSS scores,NIHSS scores at discharge,trial of Org 10172 in acute stroke treatment(TOAST)classification,laboratory indicators(fasting blood glucose,hemoglobin A1c[HbA1c],total cholesterol,triglycerides,high-density lipoprotein,low-density lipoprotein),clinical treatment information(intravenous thrombolysis,mono antiplatelet therapy,dual antiplatelet therapy,anticoagulation therapy)and length of stay.The status of stenosis and occlusion in the culprit vessel were assessed based on imaging results.Mild-to-moderate stenosis was defined as a stenosis rate of 0％to 69％,severe stenosis as a stenosis rate of 70％to 99％,and occlusion as complete interruption of the supplying artery.END was defined as an increase in NIHSS score of ≥2 points from baseline within 72 hours after admission,combined with an increase of at least 1 point in the motor score compared to the score at admission.Prognosis was assessed via telephone follow-ups at 90-day after onset using mRS score,with an mRS score ≤ 2 indicating a favorable outcome and an mRS score＞2 indicating a poor outcome.Variables with P＜0.05 in the univariate analysis were incorporated into multivariate Logistic regression analysis to identify the independent risk factors for END in mAIS patients.A nomogram model was constructed,and calibration curves along with decision curve analysis were plotted to evaluate the model's goodness-of-fit and clinical utility.Univariate and multivariate Logistic regression analyses were performed to identify factors associated with poor 90-day functional outcome after mAIS.Results(1)A total of 826 patients were included,aged 33-94 years,with a median age of 67(57,76)years.There were 571 males and 255 females.The NIHSS score at admission ranged from 0 to 5,with a median NIHSS score at admission of 3(2,4).The NIHSS motor subscore at admission ranged from 0 to 5,with a median baseline NIHSS motor score of 2(0,2).Among them,119 patients(14.4％)were in the END group and 707 patients(85.6％)were included in the non-END group.At 90days after stroke,744 patients(90.1％)had a favorable outcome,while 82 patients(9.9％)had a poor outcome.(2)Univariate analysis showed that there were statistically significant differences between the END group and the non-END group in terms of HbA1c,fasting blood glucose,baseline NIHSS score,baseline NIHSS motor subscore,history of alcohol consumption,diabetes mellitus,culprit vessel stenosis and occlusion,and TOAST classification(all P＜0.05).Statistically significant differences were observed between the favorable outcome group and the poor outcome group in HbA1c,fasting blood glucose,incidence of END,baseline NIHSS score,discharge NIHSS score,culprit vessel stenosis and occlusion,TOAST classification,and history of alcohol consumption(all P＜0.05).(3)Multivariate Logistic regression analysis indicated that mAIS patients with severe stenosis of the culprit vessel(OR,5.88,95％CI2.32-14.91,P＜0.01),occlusion of the culprit vessel(OR,5.74,95％CI 2.25-14.62,P＜0.01),history of alcohol consumption(OR,5.59,95％CI3.41-9.17,P＜0.01),elevated HbA1c(OR,1.67,95％CI 1.35-2.08,P＜0.01),and higher baseline NIHSS motor score(OR,1.43,95％CI 1.08-1.89,P=0.012)had an increased risk of END.A higher discharge NIHSS score(OR,2.59,95％CI 1.89-3.57,P＜0.01)and the occurrence of END(OR,18.42,95％CI 5.13-66.18,P＜0.01)were associated with poor 90-day functional outcome after mAIS.(4)The nomogram model constructed based on independent risk factors of END in mAIS patients demonstrated an AUC of 0.78(95％CI 0.73-0.83)for predicting END,with a sensitivity of 0.8 and a specificity of 0.7.The model showed good calibration,and the Hosmer-Lemeshow test indicated good agreement between predicted and observed values(P=0.333).Decision curve analysis revealed that the model provided a high net benefit across a range of high-risk thresholds(0.1-0.7),suggesting its potential clinical utility.Conclusions Severe stenosis of the culprit vessel,occlusion of the culprit vessel,glycated hemoglobin levels,baseline NIHSS motor subscale scores,and history of alcohol consumption are independent risk factors for END in patients with mAIS.The nomogram model constructed based on these factors demonstrated good predictive performance.END and NIHSS scores at discharge are independent predictors of poor 90-day outcomes in patients with mAIS.

Objective:To investigate the regulatory effect of long non-coding RNA (lncRNA) FTX on gastric cancer cell proliferation through miR-22-3p/NOD-like receptor protein 3 (NLRP3) inflammasome pathway.Methods:The gastric cancer cell line NCI-N87 were divided into blank control group, si-FTX-NC group, si-FTX group, si-FTX+miR-22-3p inhibitor-NC group and si-FTX+miR-22-3p inhibitor group. Quantitative real-time fluorescent PCR was performed to analyze the expression levels of lncRNA FTX and miR-22-3p, clone formation assay was performed to analyze the proliferation ability of NCI-N87 cells, western blotting was performed to analyze the expressions of NLRP3 inflammasome pathway proteins, and dual-luciferase reporter assay was performed to analyze the targeting relationship between lncRNA FTX and miR-22-3p.Results:The relative expressions of lncRNA FTX in the blank control group, si-FTX-NC group, si-FTX group, si-FTX+miR-22-3p inhibitor-NC group and si-FTX+miR-22-3p inhibitor group were 1.03±0.09, 1.01±0.15, 0.42±0.08, 0.45±0.06 and 0.46±0.13 respectively, with a statistically significant difference ( F=52.19, P<0.001). The relative expressions of miR-22-3p were 1.04±0.12, 0.97±0.08, 2.26±0.15, 2.23±0.13 and 1.15±0.11 respectively, with a statistically significant difference ( F=178.53, P<0.001). Compared with the blank control group and si-FTX-NC group, the relative expressions of lncRNA FTX in the si-FTX group, si-FTX+miR-22-3p inhibitor-NC group and si-FTX+miR-22-3p inhibitor group decreased (all P<0.001). Compared with the blank control group, si-FTX-NC group and si-FTX+miR-22-3p inhibitor group, the relative expressions of miR-22-3p in the si-FTX group and si-FTX+miR-22-3p inhibitor-NC group increased (all P<0.001). The clones of the five groups were 115.50±7.25, 112.33±8.46, 54.83±5.17, 56.17±6.32 and 85.67±9.43, with a statistically significant difference ( F=91.67, P<0.001). The levels of NLRP3 protein in the five groups were 1.84±0.17, 1.86±0.12, 0.95±0.09, 0.97±0.11 and 1.28±0.19, with a statistically significant difference ( F=60.62, P<0.001). Compared with the blank control group and si-FTX-NC group, the number of clones and the level of NLRP3 protein of the si-FTX group, si-FTX+miR-22-3p inhibitor-NC group and si-FTX+miR-22-3p inhibitor group decreased (all P<0.05). Compared with the si-FTX+miR-22-3p inhibitor group, the number of clones and the level of NLRP3 protein in the si-FTX group and si-FTX+miR-22-3p inhibitor-NC group decreased (all P<0.05). The dual-luciferase reporter assay found that miR-22-3p was the target gene of lncRNA FTX. Conclusion:Silencing the expression of lncRNA FTX can inhibit the proliferation of gastric cancer cells, and the mechanism may be related to the regulation of lncRNA FTX on the miR-22-3p/NLRP3 inflammasome pathway.

Bt Cry toxin is the mostly studied and widely used biological insect resistance protein, which plays a leading role in the green control of agricultural pests worldwide. However, with the wide application of its preparations and transgenic insecticidal crops, the resistance to target pests and potential ecological risks induced by the drive are increasingly prominent and attracting much attention. The researchers seek to explore new insecticidal protein materials that can simulate the insecticidal function of Bt Cry toxin. This will help to escort the sustainable and healthy production of crops, and relieve the pressure of target pests' resistance to Bt Cry toxin to a certain extent. In recent years, the author's team has proposed that Ab2β anti-idiotype antibody has the property of mimicking antigen structure and function based on the "Immune network theory" of antibody. With the help of phage display antibody library and specific antibody high-throughput screening and identification technology, Bt Cry toxin antibody was designed as the coating target antigen, and a series of Ab2β anti-idiotype antibodies (namely Bt Cry toxin insecticidal mimics) were screened from the phage antibody library. Among them, the lethality of Bt Cry toxin insecticidal mimics with the strongest activity was close to 80% of the corresponding original Bt Cry toxin, showing great promise for the targeted design of Bt Cry toxin insecticidal mimics. This paper systematically summarized the theoretical basis, technical conditions, research status, and discussed the development trend of relevant technologies and how to promote the application of existing achievements, aiming to facilitate the research and development of green insect-resistant materials.

Background: Cardiopulmonary resuscitation (CPR) strategies in COVID-19 patients differ from those in patients suffering from cardiogenic cardiac arrest. During CPR, both healthcare and non-healthcare workers who provide resuscitation are at risk of infection. The Working Group for Expert Consensus on Prevention and Cardiopulmonary Resuscitation for Cardiac Arrest in COVID-19 has developed this Chinese Expert Consensus to guide clinical practice of CPR in COVID-19 patients. Main recommendations: 1) A medical team should be assigned to evaluate severe and critical COVID-19 for early monitoring of cardiac-arrest warning signs. 2) Psychological counseling and treatment are highly recommended, since sympathetic and vagal abnormalities induced by psychological stress from the COVID-19 pandemic can induce cardiac arrest. 3) Healthcare workers should wear personal protective equipment (PPE). 4) Mouth-to-mouth ventilation should be avoided on patients suspected of having or diagnosed with COVID-19. 5) Hands-only chest compression and mechanical chest compression are recommended. 6) Tracheal-intubation procedures should be optimized and tracheal-intubation strategies should be implemented early. 7) CPR should be provided for 20-30 min. 8) Various factors should be taken into consideration such as the interests of patients and family members, ethics, transmission risks, and laws and regulations governing infectious disease control. Changes in management: The following changes or modifications to CPR strategy in COVID-19 patients are proposed: 1) Healthcare workers should wear PPE. 2) Hands-only chest compression and mechanical chest compression can be implemented to reduce or avoid the spread of viruses by aerosols. 3) Both the benefits to patients and the risk of infection should be considered. 4) Hhealthcare workers should be fully aware of and trained in CPR strategies and procedures specifically for patients with COVID-19.

Objective To explore the clinical efficacy and safety of off-clamping in robotic-assisted partial nephrectomy (RAPN) for the treatment of renal tumors.Methods From January 2015 to March 2017,the data of 48 patients who underwent off-clamping RAPN were reviewed retrospectively.There were 31 males and 17 females,and the mean age was 57 years (range:23-84 years).The mean tumor size was 3.1 cm (range:1.2-6.4 cm),with the upper,middle,and lower polar tumors account for 35.4％,27.1％,and 37.5％,respectively.The clinical tumor stage was T1N0M0 in all 48 cases,according to the AJCC tumor staging system for renal cancer.Results RAPNs were performed successfully in all 48 cases,without conversion to open surgery.In those patients,the application of off-clamping in robotic-assisted partial nephrectomy was performed in 44 cases.The renal artery and vein was exposed,dissected,isolated and then clamped in 4 cases due to bleeding.The mean surgical time was 85 min (range:75-185 min).The mean estimated blood loss was 134 ml (range:60-270 ml),and no blood transfusion was needed.The wound surface was closed using interrupted suture with Hem-o-lok clips securing each needle point.The mean time for renorrhaphy was 22 min (rang:11-31 min).No intraoperative severe complications such as vascular injury,trauma of abdominal organ occurred.There were 5 complications,including 2 cases of hematuria,2 cases of delayed healing of incision,and 1 case of pneumohypoderma.The pathological diagnosis included 40 cases of renal clear cell carcinoma,3 cases of papillary renal cell carcinoma,and 5 cases of angiomyolipomas.No tumor recurrence or distant metastasis was observed during the average follow-up of 17 months (range 3-27 months).Conclusions Off-clamping RAPN is safe and feasible approach to excise certain kidney tumors.It carries the benefits of less complication,quick recovery,and less ischemia reperfusion renal injury.Off-clamping RAPN would be suitable for those patients with solitary kidneys,renal insufficiency,and bilateral tumors.

Objective To investigate the iodine nutritional and thyroid stimulating hormone level of patients with thyroid nodules in different regions of Qinghai Province and analyze the characteristics of changes in different regions.Methods In 2014-2016,thyroid nodules in 9 regions of Qinghai Province (Tibetan areas:Xiewu,Nangqian,Jiegu,Guoluo;non-Tibetan areas:Xining,Huzhu,Menyuan,Minhe,and Ledu) were selected and serum thyroid stimulating hormone (TSH) and urine iodine were measured.Results A total of 553 thyroid nodules,the median urinary iodine (MUIC) was 160.8 μg/L and the median TSH was 2.97 mU/L.The iodine nutritional status was at an appropriate level.Among them,MUIC (206.8 μg/L) in thyroid nodules in the Menyuan area was slightly higher than the appropriate amount,there was a significant difference in MUIC among different region (x2 =47.747,P ＜ 0.05);of TSH in thyroid nudules in the 9 regions,the differences were statistically significant (x2 =34.832,P ＜ 0.05).Non-Tibetan areas were compared with Tibetan areas,there was a significant difference in MUIC (155.6,185.6 μg/L),TSH (2.68,3.45 mU/L,Z =-3.677,-5.410,P ＜ 0.05);Among them,the differences was statistically significant between MUIC (152.8,187.7 μg/L) of women with thyroid nodules (Z =-3.504,P ＜ 0.05);there was a statistically significant difference in TSH levels among men (2.58,3.46 mU/L) and women (2.80,3.44 mU/L) with thyroid nodules (Z =-3.613,-4.040,P ＜ 0.05);there were no significant differences in MUIC levels among thyroid nodules of each age groups (P ＞ 0.05);of the TSH level in 30-and 50-＜ 65 years groups (2.63,3.17;2.25,3.58 mU/L),the differences were statistically significant (Z =-2.892,-3.233,P ＜ 0.05),and other groups were no significant differences (P ＞ 0.05).Conclusion The iodine nutrition of patients with thyroid nodules in these regions of Qinghai Province is generally at an appropriate level,the MUIC and TSH levels in Tibetan areas were lower than those in non-Tibetan areas,and iodine nutrition status and TSH levels should be monitored for key populations.

Objective To summarize our experience in robotic-assisted laparoscopic surgery for adrenal diseases Methods The clinical data of 243 patients with adrenal tumor treated by robotic-assisted laparoscopic surgery from March 2010 to February 2017 were retrospectively reviewed.There were 99 men and 144 women.The mean age was 51.6 years (range, 19-84).Tumors located at left adrenal in 140 cases, right in 97 cases,and both sides in 6 cases.The average diameter was 3.32 cm (range, 0.8-12 cm).However, there were 41 cases whose tumor diameter were greater than 5 cm.Results There were 2 cases of conversion during operation, 1 case converted to open surgery and the other to the traditional laparoscope surgery.The mean operative time was 35 min (range, 20-130 min).Estimated blood loss was 80 ml (range,20-1 200 ml).Blood transfusion was needed in 6 cases.The mean postoperative hospital stay was 5d (range, 3-20 d).The pathological diagnosis included 37 cases of pheochromocytoma, 149 cases of cortical adenoma, 3 cases of cortical carcinoma, 5 cases of metastatic tumor, 9 cases of adrenal myelolipoma, 3 cases of adrenal cyst, 2 cases of bronchogenic cyst, 25 cases of adrenal nodular hyperplasia,2 cases of angiomyolipomas, 1 case of mature teratoma, 1 case of diffuse large B-Cell lymphoma, 1 case of angioma, and 4 cases of neurofibromatosis.Conclusions Robotic-assisted laparoscopic adrenalectomy was safe and effective.Robotic-assisted laparoscopic surgery has the advantages over laparoscopic surgery in treatment of complicated adrenal tumor, such as large adrenal tumors, pheochromocytoma, bilateral adrenal diseases, overweight and obese patients with adrenal diseases.
