Serum free fatty acids were isolated with trichloromethane and esterified with boratotrifluoricether/methanol. Heptadecanoic acid (17:0) was used as internal standard. The recovery rate of this method was 86.4% and coefficient of variation was 6.9%. The mean level of 25 normal adult serum samples was coincident with the data reported.

The total fatty acid in adipose tissue and total and free fatty acid in plasma, using tridecanoic (Cl3:0) and heptadecanoic acid (Cl7:0) as the internal standard (IS) respectively, were analysed by GC. In analysing total fatty acid, the esterification rate was 103.53% (IS Cl3:0) and 102.86% (IS C17:0); the recovery of lauric, myristic, stearic and arachidic acid was 101.0-103,3%, 102,1-494.1%, 103,1-104.5% and 100,0-105.0%; the CV of individual fatty acid were within the range of 2.24-8.46%. In analysing free fatty acid, the esterification rate in use of C17: 0 as the IS was 102.99%; the recovery of lauric, myristic, stearic and arachidic acid was 83.5-87.3%, 96.4-99.6%, 94.3-101.9%, and 82.0-105.0% respectively, the CV of individual fatty acid were within the range of 1.41-6.21%. The procedure analysing total fatty acid is especially simple, speedy, and reliable.

According to the analysis of 9 237 hospitalized type 2 diabetic patients, the prevalence of diabetic retinopathy ( DR )was 32.9％ , with the prevalence of mild, moderate, and serious non-proliferative DR and proliferative DR being 10. 1％, 18. 3％, 3.2％, and 1.3％ respectively. The prevalence of diabetic macular edema ( DME ) was 3.56％ in type 2 diabetics and i 0. 8％ in patients with DR. Diabetes duration and proteinuria were the common risk factors of DR and DME.

Through retrospective analysis of the clinical and laboratory data of 1 466 inpatients with type 2 diabetes mellitus(T2DM),we investigated the prevalence of chronic kidney disease (CKD) and analyzed the risk factors.The prevalence of CKD in hospitalized patients with T2DM was 52.25％.In the patients with CKD,protein urine was present in 93.47％ of the cases,27.93％ of them had glomerular filtration rate(eGFR) ≤60 ml · min-1 · 1.73 m-2,damage of renal tubular function was present in 24.28％,and abnormal renal imaging in 14.88％.Logistic regression showed that age,body mass index(BMI),duration of diabetes,systolic blood pressure,serum uric acid,low density lipoprotein-cholesterol (LDL-C),and smoking were independently associated with patients of T2 DM and CKD.The prevalence of CKD was increased with aging,diabetic course,BMI,and LDL-C.CKD is a common chronic complication in patients with T2DM,especially in patients with prolonged course,advanced age,and obesity.Much attention should be paid to early detection of CKD in patients with diabetes.In addition to detecting urinary protein and eGFR,renal tubular function and morphological examination should also be included.

Objective To study the expression and clinical significance of Livin ( anti-apoptosis protein) and Smac (promoting apoptosis factor) in patients with the non-Hodgkin lymphoma (NHL).Methods The expression of Livin and Smac were detected by immunohistochemical staining(SP) assay in 31 patients with NHL, and the relationship between Livin/Smac and clinical staging, IPI and prognosis were analyzed. Results The patients with positive expression of Livin had B symptom, high risk IPI, late clinical staging (Ⅲ/Ⅳ stage) and short survival time, while the ones with positive expression of Smac had no B symptom, early clinical staging( Ⅰ /Ⅱ stage), low risk IPI and good prognosis. The expressions of both Livin and Smac were not related to gender and age. Expression of Livin was not correlated to that of Smac (r =0.003,P ＞0.05). Conclusion For patients with NHL, the expression of Livin protein was related to poor prognosis and adverse clinical features, whereas the expression of Smac protein was related to good prognosis and clinical feature.

OBJECTIVE: To explore the different character of children from 0 to 3 years old, understand their psychological features, give guidances about nurturing and educating children, and supply theoretical base for preventing problems of children behaviors. METHOD: Two hundred and fifty-one children patients from 0 to 3 years old were surveyed from clinic of maternal and child health care with children character software and questionnaire. RESULT: Among all characters, 32.3% children were easy and medium nurturing type, 31.1% easy nurturing type, 23.1% difficult nurturing type, 7.5% slow startup and 6.0% difficult and medium type. CONCLUSION Main character of children from 0-3 years old are easy and medium nurturing type and easy nurturing type. Children with different ages and sexes have different characters, so pertinent education and guidance should be given according to characters of different ages and sexes so as to improve their health.

Primary seminal vesicle adenocarcinoma is a rare malignant tumor of reproductive system. A 21-year-old patient with primary seminal vesicle adenocarcinoma was treated in our hospital in August 2014. Without surgical treatment, the patient survived for 4.5 years after 6 cycles of chemotherapy and pelvic radiotherapy. Local recurrence was found in February 2019 and laparoscopic radical prostatectomy was performed. There was no local recurrence and metastasis after follow-up for 10 months.

Objective To investigate the relationship and clinical significance between the concentration of 25-hydroxy vitamin D3 [25-(OH)D3 ]in the serum and community-acquired pneumonia(CAP)in infants.Methods The study recruited 98 infants.There were 68 cases of mild pneumonia and 30 cases of severe pneumonia.The con-centration of 25-(OH)D3 in serum,IgA and alkaline phosphatase(AKP)were measured.33 infants who accepted physical examination in the outpatient department were selected as control group at the same time.Results The serum 25-(OH)D3 concentration of severe pneumonia was (21.09 ±7.32)ng/mL,mild pneumonia was (25.77 ± 8.06)ng/mL and the control group was (37.13 ±6.94)ng/mL.The differences among the three groups had statisti-cally significant differences(t =9.18,3.72,5.34,all P <0.05).The differences of serum IgA concentration among the three groups had statistically significant differences (t =5.42,3.96,8.92,all P <0.05).But serum AKP concen-tration among the three groups had no statistically significant differences(t =0.86,0.58,0.47,all P >0.05).The prevalence of Vitamin D deficiency was 40.0%,which was higher than mild pneumonia patients(20.6%)and the healthy children(9.1%)(χ2 =8.43,17.55,all P <0.05).Conclusion The serum 25-(OH)D3 concentration and IgA of CAP patients were lower than healthy children,especially in severe pneumonia cases.The prevalence of Vita-min D deficiency was significantly higher than healthy children.There were no relevance between the serum concentra-tion of 25-(OH)D3 ,IgA and AKP.25-(OH)D3 plays an important role in the development of CAP.The low level of serum 25-(OH)D3 concentration may be one of the risk factors and has correlation to the severity of pneumonia.

Objective:To explore the interaction needs between depressed adolescents with non-suicidal self-injury behavior and their parents.Methods:From June to November 2023, purposive sampling was used to select depression adolescents with non-suicidal self-injury behavior and their parents admitted to Huai'an Third People's Hospital as respondents. The semi-structured interview was used to collect data. The paired interview and Colaizzi 7-step analysis methods were used to analyze and summarize interview data.Results:Fifteen pairs of adolescents and their parents were interviewed. The needs of depressed adolescents with non-suicidal self-injury behavior for parental attention were summarized as controlling emotions, empathetic perception, reducing stress, mental dependence, autonomous decision-making, and mutual respect. The needs of parents for depressed adolescents with non-suicidal self-injury behavior were summarized as overcoming depression, restoring education, emotional response, actively seeking help, deep communication, and easing relationships.Conclusions:There are various interactive needs between depressed adolescents with non-suicidal self-injury behavior and their parents, which are closely related but contradictory in coping with the illness. It is recommended that medical and nursing staff conduct research on patients and their parents as a whole and provide personalized and targeted two-way guidance and emotional support through in-depth understanding and careful consideration of the multi-level interaction needs of both parties.
