In April 2022,an epidemic occurred in Gongshu District,Hangzhou,where Zhejiang Cancer Hospital is loca-ted.And the hospital was confronted with the most extensive,the most unusual and the most urgent public health emergency crisis since its establishment.Taking patients as the core and proceeding from the public perspective,an authoritative voice of a hospital was conveyed in a timely and accurate manner,which demonstrated the hospital's resolution and executive power in the crisis.Based on Malcolm Gladwell's"tipping point"theory,the paper reveals the situation of online public opinion caused by the sudden epidemic and its response,discusses the hospital's communication practices in handling public health emergencies and provides hospitals with practical reference for brand promotion and operation.

Objective To investigate the distributions of vitamin K1 and K2 in infants of different age groups by comparing the serum levels of vitamin K1 and K2 in them.Methods 1177 infants from 0 to 3 months were divided into 6 age groups.Those born/treated in the subject units(pediatrics,neonatology,child health care,obstetrics)were selected as the study subjects and grouped by age:0～3 days(591 cases),4～7 days(255 cases),8～5 days(104 cases),1 month(118 cases),2 months(40 cases),and 3 months(69 cases).General data of the infants were collected,and the serum vitamin K1 and K2 levels were determined by HPLC-mass spectrometry(LC-MS)on a unified platform,and analyzed from the distribution of vitamin K1 and K2 at different ages.Results The distributions of vitamin K1 and K2 levels were statistically significant(P<0.001);newborns were highly vulnerable to vitamin K1 deficiency,and vitamin K2 deficiency was higher than vitamin K1 with age.Conclusion Maintaining the normal growth of vitamin K1 and K2 is crucial for the normal growth and development of infants of all ages,so we should pay close attention to the monitoring and supplement of vitamin K1 and K2.

The ultimate goal of cardiac arrest-cardiopulmonary resuscitation (CA-CPR) is to reduce brain damage and promote neurological recovery. Although the return of spontaneous circulation (ROSC) has improved, the proportion of patients who survive to discharge is very low, so how to evaluate the recovery of brain function after resuscitation is particularly important in clinical work. From a clinical perspective, although early prognostic indicators are not perfect, identifying high-risk features may help clinicians determine the severity of brain injury caused by a patient's potential course of disease. This review, based on recent literature, selects several commonly used clinical brain function evaluation indicators to provide theoretical and practical support for assessing brain function recovery in patients after CPR.

OBJECTIVE: To investigate the survival of patients with cardiac arrest and cardiopulmonary resuscitation (CA-CPR), and to analyze the factors influencing survival at 30 days after restoration of spontaneous circulation (ROSC). METHODS: A retrospective cohort study was conducted. Clinical data of 538 patients with CA-CPR admitted to the People's Hospital of Ningxia Hui Autonomous Region from January 2013 to September 2020 were enrolled. The gender, age, underlying disease, cause of CA, type of CA, initial rhythm, presence or absence of endotracheal intubation, defibrillation, use of epinephrine, and 30-day survival rate of patients were collected. The etiology of CA and 30-day survival rate among patients with different ages were compared, as well as the clinical data between patients who survived and died at 30 days after ROSC were also compared. Multivariate Logistic regression was used to analyze the relevant factors affecting the 30-day survival rate of patients. RESULTS: Among 538 patients with CA-CPR, 67 patients with incomplete information were excluded, and 471 patients were enrolled. Among 471 patients, 299 were males and 172 were females. Aged from 0 to 96 years old, 23 patients (4.9%) were < 18 years old, 205 patients (43.5%) were 18 to 64 years old, and 243 patients (51.6%) were ≥ 65 years old. 302 cases (64.1%) achieved ROSC, and 46 patients (9.8%) survived for more than 30 days. The 30-day survival rate of patients aged < 18 years old, 18-64 years old and ≥ 65 years old was 8.7% (2/23), 12.7% (26/205) and 7.4% (18/243), respectively. The main causes of CA in patients younger than 18 years were severe pneumonia (13.1%, 3/23), respiratory failure (13.1%, 3/23), and trauma (13.1%, 3/23). The main causes were acute myocardial infarction (AMI; 24.9%, 51/205), respiratory failure (9.8%, 20/205), and hypoxic brain injury (9.8%, 20/205) in patients aged 18-64 years old, and AMI (24.3%, 59/243) and respiratory failure (13.6%, 33/243) in patients aged ≥ 65 years old. Univariate analysis results revealed that the 30-day survival rate of patients with CA-CPR may be related to the the cause of CA was AMI, initial rhythm was ventricular tachycardia/ventricular fibrillation, endotracheal intubation and epinephrine. Multivariate Logistic regression analysis results showed that CA was caused by AMI [odds ratio (OR) = 0.395, 95% confidence interval (95%CI) was 0.194-0.808, P = 0.011] and endotracheal intubation (OR = 0.423, 95%CI was 0.204-0.877, P = 0.021) was a protective factor for 30 days of survival after ROSC in patients with CA-CPR. CONCLUSIONS The 30-day survival rate of CA-CPR patients was 9.8%. The 30-day survival rate of CA-CPR patients with AMI after ROSC is higher than that of patients with other CA causes, and early endotracheal intubation can improve the prognosis of patients.

Objective: To evaluate the effectiveness of enteral nutrition in children with accidental upper gastrointestinal injury. Methods: The medical records of 128 patients with mechanical or chemical gastrointestinal mucosal injury, who were hospitalized in Department of Gastroenterology, Children's Hospital of Zhejiang University School of Medicine from January 1, 2011 to December 30, 2017, were collected. All cases were treated with enteral nutrition. The clinical features and etiologies were retrospectively analyzed. Weight-for-age Z score and lab findings including white blood cells, C-reactive protein, neutrophils, albumin, prealbumin, urea nitrogen and hemoglobin before and after treatment were extracted. The clinical characteristics, the duration of enteral nutrition and gastrointestinal mucosal healing between different etiologies were further analyzed. Normal distribution variables and categorized variables were compared with t test and χ² test respectively, and abnormal distribution data was compared with Wilcoxon test. Results: Among all the cases, 77 were males and 51 were females. The average age was (29±22) months. The mean duration of hospitalization and enteral nutrition were (11±7)d and (27±20)d respectively. Vomiting was the most common clinical presentation (72 cases, 56.3%). In 79 cases the problems were caused by mechanical injury, among which coins were most commonly seen. The rest 49 cases were caused by chemical injury. However, the duration of hospitalization ((13±8) d vs. (10±6)d, t=-3.089, P=0.002) and enteral nutrition ((39±22) vs. (19±14) d, t=-5.365, P=0.000) were longer in children with chemical injury than those with mechanical injury. A total of 112 cases got complete blood count and C-reactive protein both before and after enteral nutrition. Inflammatory markers, including leukocytes ((7.7±2.7) ×10⁹/L vs. (13.7±5.0) ×10⁹/L, t=12.244, P <0.05), neutrophils ((3.4±1.9)×10⁹/L vs. (9.4±4.6) ×10⁹/L, t=13.655, P<0.05), and C-reactive proteins (5.0(3.0,7.8) vs. 13.5(6.0,40.5) mg/L, Z=7.776, P <0.05) were significantly decreased. The nutritional markers, including the weight-for-age z score (-0.1 ± 1.0 vs. 0.0 ± 1.0, t=-2.622, P=0.010) and the prealbumin (0.1 ± 0.1 vs. 0.2 ± 0.0 g/L, t=-3.671, P=0.001) were significantly increased. Fifty-five (82.1%) children in mechanical injury group recovered in 4 weeks, while 27 (79.4%) children in chemical injury group recovered in 7 weeks. Conclusion Enteral nutrition can provide adequate nutritional requirements for children with upper gastrointestinal injury, and may help to decrease imflammation and improve mucosal healing.

BACKGROUND:Hip segmentation based on CT image has been widely used in computer-assisted surgery planning, prosthesis design and finite element analysis. OBJECTIVE:To explore application effects of automatic segmentation method for hip joint based on Bayesian Decision Theory in computer-assisted hip surgery. METHODS:An accurate outer surface segmentation and extraction remain chal enging due to deformed shapes and extremely narrow inter-bone regions. In this paper, we present an automatic, fast and accurate approach for segmentation of femoral head and proximal acetabulum. The outline of the femur was segmented and extracted by contrast enhancement, thresholding algorithm and region growth algorithm. The boundaries of the bone regions are further refined based on Bayes decision rule. RESULTS AND CONCLUSION:Automatic segmentation method for hip joint based on Bayesian Decision Theory is an accurate segmentation technique for femoral head and proximal acetabulum and it can be applied in computer-assisted hip surgery and prosthesis design.

OBJECTIVETo investigate the efficacy of infliximab versus corticosteroids in achieving clinical remission in pediatric patients with Crohn's disease in China.

METHODData of all newly diagnosed active Crohn's disease pediatric cases seen from June 2009 to December 2013 in Children's Hospital, Zhejiang University School of Medicine were retrospectively recorded and reviewed.

INCLUSION CRITERIAthe age of the children was less than 18 years; pediatric Crohn's disease activity index (PCDAI) was more than 10; infliximab or corticosteroids were used for inducing remission; infliximab, immunosuppressive medications or mesalamine was prescribed for maintaining remission. Patients in steroids group were followed up for more than 1 year. The enrolled patients were divided into two groups: infliximab group and steroids group. Clinical data, laboratory findings and side effects of the medications were collected at week 2, 4, 12, 24 and 48. PCDAI and Crohn's disease endoscopic index score (CDEIS) were calculated. Clinical response rate, clinical remission rate, relapse rate, mucosal healing and growth were evaluated.

RESULTEleven children received infliximab therapy and 11 subjects received corticosteroids. In Infliximab group, 6, 5 and 7 patients were in clinical remission at week 2, 4, and 8, while so were 6, 9, and 9 patients in steroids group. The difference was not statistically significant (χ² = 0.00, 3.14, 0.92, P > 0.05). In infliximab group, 8, 8, and 11 patients were in clinical remission at week 2, 4, and 8, so were 8, 9, and 9 patients in steroids group. The difference was not statistically significant (χ² = 0.00,0.26, 2.20, P > 0.05). When compared with data at baseline, significant decreases were observed in the median PCDAI between the two groups at week 2, 4, and 8 (all P < 0.05). But there were no significant differences between two groups at week 2, 4, and 8 (all P > 0.05). At week 12, 24 and 48, 8/11, 7/8, 3/5 cases on infliximab versus 7/11, 9/11, 8/11 cases on steroids maintained remission. There was no significant differences between the two groups (all P > 0.05). In 7 patients and 9 patients remission was successfully induced at week 8. The relapse rate was similar at week 12, 24, and 48 (χ² = 0.83, 0.09, 1.00, all P > 0.05). Height for age Z score in infliximab group was significantly higher than that in steroids group at week 24 (P < 0.05). Body mass index Z score between the two groups at week 8, 24, and 48 were not statistically significant (all P > 0.05). Of the children treated with infliximab, 3 developed side effects. All the children treated with steroids got Cushing's syndrome.

CONCLUSIONIn children with Crohn's disease, infliximab therapy is as effective as corticosteroids to induce remission.Less side effects were observed with infliximab therapy compared with immunosuppressive medication and mesalamine.

Results There was no statistical difference in age and foreskin status between the two groups (P＞0.05).For the Shang Ring group,the operation time was(5±1)rain,blood loss was (0.98±1.14)ml,pain score during operation was 0.25±0.54,24-hour pain score after operation was 1.63±0.87,the postoperative complication rate was 6.89% (33/479),wound healing time was (20±5)d,the satisfaction rate of appearance was 99.79% (478/479),and treatment cost was (871±52) yuan.For the conventional group,the operation time was (27±5) min,blood loss was (8.30±3.60)ml,pain score during operation was 3.29±1.57,24-hour pain score after operation was 5.56±1.42,the postoperative complication rate was 13.28%(47/354),wound healing time was (13±2)d,satisfaction rate of appearance was 92.37% (327/354),and treatment cost was (554±46) yuan.Compared with the conventional group,the Shang Ring group had a shorter operation time,less blood loss,less pain score,higher appearance satisfaction rate and a lower complication rate (P＜0.05).But wound healing time was longer and treatment cost was higher in the Shang Ring group (P＜0.05). Conclusions Chinese Shang Ring circumcision is simpler and an improved approach over conventional circumeision with shorter operative time,less blood loss,less pain,relatively lower complication rate and higher satisfaction and acceptability.

Objective To investigate the effect of Aidi injection combined with chemotherapy on CD+4CDhi25CDlow127regulatory T (Treg) cells in peripheral blood of advanced non-small-cell lung cancer (NSCLC).Methods Sixty patients with advanced NSCLC were randomly divided into the study group (treated with Aidi injection combined with chemotherapy) and the control group (treated with chemotherapy).The levels of CD+4CDhi25CDlow127Treg cells were detected by flow cytometry (FCM), and TGF-β1 and IL-10 levels were determined by enzyme linked immunosorbent assay (ELISA) before and after chemotherapy. A group consisted of 20 healthy persons was set up meanwhile.Results There was a significantly higher percentage of CD+4CDhi25CDlow127Treg cells in patients with NSCLC (5.77±1.50) % than that(3.84±0.96) % of healthy volunteers (P=0.000).The IL-10 and TGF-β1 levels[(24.09±6.74), (197.76±43.76) ng/ml]in the serum of patients with NSCLC were also significantly higher than that[(19.39±5.73), (141.13±32.17) ng/ml]of healthy volunteers (P =0.006,P =0.002). In control group, levels of CD+4CDhi25CDlow127 Treg cells were obviously lower than that before chemotherapy (P =0.048).Levels of TGF-β1 and IL-10[(22.25±6.79), (184.85±49.11) ng/ml]were slightly decreased, which showed no significant difference contrast to pretherapy[(24.37±8.10), (197.16±44.57) ng/ml](P =0.276, P =0.314).In study group, levels of CD+4CDhi25CDlow127Treg cells and TGF-β1, IL-10[(4.36±1.19) %,(20.16±4.73), (165.42±39.57) ng/ml]were obviously lower than that before chemotherapy[(5.78±1.50) %,(23.81±5.15), (198.35±43.68) ng/ml](P=0.000, P=0.003, P =0.006).Conclusion The CD+4CDhi25CDlow127 Treg cells in the peripheral blood of advanced NSCLC patients is significantly increased. Aidi injection combined with chemotherapy can obviously reduce the level of CD+4CDhi25CDlow127 Treg cells in patients with advanced NSCLC, and the combined therapy could improve the immune function of patients.
