Objective To investigate the indication and timing of surgery for acute necrotizing pancreatitis. Methods 82 cases of acute necrotizing pancreatitis were analyzed retrospectively. 10 cases were treated non-operatively. Early operation was performed on 44 cases, while 28 cases underwent surgery on late stage. Results The overall morbidity and mortality was 24% and 18%, respectively. All 10 patients in the non-operative group were cured with a morbidity of 10%. The morbidity and mortality in the early operation group was 14% and 11%, respectively, compared with 46% and 36% of those receiving surgery on late stage(P<0.01, P<0.05). Among those in late surgery group, patients not complicating infection had significant lower morbidity and mortality rate than those suffering from severe infection or organ dysfunction(P<0.01, P<0.05). Conclusions Early operation is necessary for some severe cases.In patients with severe pancreatic necrosis surgery should be performed before severe infection occurs.

Objective:To investigate the evaluation of disease perception, treatment compliance and community follow-up services of community schizophrenia patients, family members and personnel in Shantou City, and to provide a reference basis for improving the quality of management treatment.Methods:With the method of stratified sampling qualitative research, a community sample of 17 198 patients with schizophrenia in seven districts or county in Shantou City were sampled from February to August 2019, with 2 towns being drawn from each district or county, and 10 patients, 10 family members and 3 personnel were selected in each town. The evaluation of disease perception, treatment compliance and community follow-up services were investigated and analyzed. Respondents were eventually included in 137 patients, 138 family members and 41 personnel.The interviewees were conducted with semi-structured interviews, the data were collected according to traditional methods, and the descriptive statistical analysis was carried out with SPSS 12.0.Results:(1)34.3% of patients and 32.6% of the family members were not fully aware of the disease.22.6% of the patients and 23.2% of the family members had a sense of ill shame. (2)26.3% of patients did not comply with treatment, 29.9% of patients had not insight, 53.3% of patients and 24.6% of family members on the side effects of drugs and addiction understood improperly, and, 35.0% of patients and 13.0% of the family had a misunderstanding of illness and using drugs. (3)29.2% of patients and 31.2% of their families were tired of taking long-term medication, 24.8% of patients and 21.0% of their families felt socially isolated, and, 17.5% felt unsupported and 18.8% of their families admitted that they did not care enough about patients. (4)31.4% of patients did not actively receive follow-up services, 37.2% of patients and 20.3% of family members did not cooperate with follow-up doctors, and, 21.2% of patients and 10.1% of family members were not satisfied with follow-up services. (5)The personnel of psychiatric care could basically grasp the conditions of patients in the jurisdiction and carried out follow-up services on a regular basis (90.2%), master emergency disposal methods (92.7%), and have carried out training (97.6%). However, the psychiatric practice of the personnel were lower than (58.5%) and most lying part-time (78.0%), the average length of service was 5.7±1.4 years. The personnel satisfaction with the community follow-up service was higher (95.1%), but most of them thought that the psychiatric care was more difficult (36.6%), and were dissatisfied with the multi-functional staff to undertake a number of public services (31.7%).Conclusion:The management treatment project of mental disorders services in Shantou City show initial results.The patients were satisfied with the community follow-up service, but the patients and their families still have low level of cognition, poor compliance, obvious negative emotions, and have concerns about drug treatment.It is necessary to strengthen the professionalization of personnel, to carry out early mental health education and rational emotional behavior training for patients and their families.

Objective To study the possible causes of ST-elevated acute myocardial infarction (STEAMI) occurring one month after percutaneous coronary intervention (PCI). Methods One hundred and ninety two patients aged from 40-79 years who had a successful previous PCI and also received primary PCI due to STEAMI in this hospitalization were included in this study. The AMI-related lesions and previous angiographic findings such as the number of lesions, the degree of the stenosis, the type of stents and the acute results of last PCI, etc. were recorded in detail. If the AMI-related lesion was localized in-stents or at the edge of stents (distance from the edge ≤5 mm), it was defined aslate thrombosis, otherwise it was regarded as an AMI induced by new-lesion. Results New lesions, as the cause of STEAMI, were found in 144 cases (Group A, 75%), and late thrombosis in 48 patients (Group B, 25%). There was a significant difference in the average time from previous PCI to AMI (30.1±12.4 vs. 20.3±11.9 months) between the two groups. Diabetes mellitus (DM) and drug-eluting stents (DES) utilization were associated with markedly higher morbidity of late thrombosis in adjusted logistic regressionanalysis [hazard ratio (HR) 3.387, 95% CI 1.053-10.898 and HR 5.311, 95% CI 1.066-26.464]. Conclusions STEAMI occurred 1 month after PCI are more likely to be developed from previous insignificant lesions than from late thrombosis in stents. Moreover, DM and DES are associated with a high incidence of late thrombosis, which may indicate that intensive antiplatelet therapy should be considered in diabetic patients receiving PCI.

OBJECTIVETo explore the relation between genetic polymorphisms of NQO1, GSTT1 and risks of chronic benzene poisoning (BP).
METHODSA case-control study was conducted. 152 BP patients and 152 workers occupationally exposed to benzene without poisoning manifestations were investigated. Polymerase chain reaction (PCR), denaturing high-performance liquid chromatography(DHPLC) and sequencing were used to detect the single nucleotide polymorphisms(SNPs) of the promoter and complete coding-region of NQO1 gene. Multiple PCR was used to detect GSTT1 genotype.
RESULTSIn smoking population, there was 7.73-fold (95% CI: 1.71-34.97, P = 0.010) of risk in BP subjects carrying NQO1c. 609 T/T genotype, compared with those carrying C/C and C/T. genotype. In drinking population, the individuals carrying the 6th extron of NQO1c. 609 T/T homozygote genotype had a 11.00-fold(95% CI: 1.89-63.83, P = 0.005) risk of BP compared to those with NQO1c. 609 C/T and C/C genotypes.
CONCLUSIONThe subjects carrying NQO1c. 609 T/T genotype and together with the habit of smoking or drinking may be more susceptible to BP.
