AIM: To analyze the screening status of neonatal fundus disease and the related influencing factors of common fundus retinal hemorrhage in Longhua District of Shenzhen, so as to provide references for the prevention, screening and intervention of neonatal fundus disease in clinical practice.METHODS: A total of 3 101 neonates who received fundus screening in the People's Hospital of Longhua, Shenzen from September 2019 to October 2022 were selected as research objects. The screening results were summarized, and the risk factors for neonatal retinal hemorrhage were analyzed by Logistic regression model.RESULTS: The detection rate of neonatal fundus abnormalities was 12.71%, and the detection rate of neonatal retinal hemorrhage was the highest(12.19%). The other types of fundus abnormalities included periretinal white focus, chromatosis, pigment shedding, choroid coloboma and nystagmus. Hemorrhage grade I accounted for the largest proportion of 378 neonates with retinal hemorrhage(75.66%). Follow-up found that different grades of retinal hemorrhage could be automatically absorbed over time without excessive intervention. Logistic analysis suggested that spontaneous delivery [OR=3.180, 95%CI(1.543～6.555)], twin pregnancy [OR=2.119, 95%CI(1.121～4.007)] and umbilical cord round the neck [OR=1.547, 95%CI(1.239～1.930)] were risk factors affecting neonatal retinal hemorrhage.CONCLUSION: Retinal hemorrhage is the most common type of fundus abnormalities in neonates. Spontaneous delivery, twin pregnancy and umbilical cord around the neck are risk factors of retinal hemorrhage. It is recommended that pay attention to the above factors and choose appropriate intervention means to avoid serious fundus complications.

Objective: The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population. Methods: The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models. Results: A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices). Conclusion An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.

OBJECTIVETo investigate melamine-induced pathological changes in the kidney.

METHODWistar rats were fed with a diet containing 0, 1% and 2% melamine for 15 weeks. After melamine feeding was stopped, various outcome measures were observed for 4 weeks.

RESULTRats fed with melamine showed reduced caloric intake, slower weight gain and impaired renal function. The blood urea nitrogen of group A and B [(13.23 ± 5.10) mmol/L and (18.30 ± 5.90) mmol/L, respectively] and serum creatinine levels of group B [(19.90 ± 2.90) mmol/L] were higher than that of group C [(8.23 ± 2.30) mmol/L and (10.04 ± 1.73) mmol/L](P < 0.01, respectively). Additionally, the kidney coefficients of group A and B were higher than that of group C (P < 0.01, respectively). Crystals, tubular ectasia and interstitial inflammation and fibrosis were found in the kidneys of melamine fed rats. Four weeks after discontinuation of feeding with melamine-contained diet, the caloric intake and weight of the rats increased, the coefficients of the kidney decreased, and the blood urea nitrogen of group A and B [(17.96 ± 2.04) mmol/L and (19.20 ± 3.36) mmol/L, respectively] and serum creatinine levels of group B [(24.20 ± 5.28) mmol/L], which became worse than 4 weeks before (P < 0.01;P < 0.05, respectively), and were still higher than that of group C [(8.30 ± 1.79) mmol/L and (9.87 ± 2.71) mmol/L, P < 0.01, respectively]. Crystals remained inside the kidney, changes in the renal interstitium did not improve.

CONCLUSION(1) Melamine-induced urinary calculus rat model can be established by feeding 3-week old male Wistar rats with a diet containing 2% melamine for 15 weeks. The main constituent of the urinary calculus was melamine (> 90%), with a little uric acid and traces of cyanuric acid. (2) Melamine damaged the renal function, formed renal crystals, and led to the pathological changes of kidneys. All the influences seemed to be dose-depended and was related with the obstruction of the crystals or calculus in the kidney. (3) The renal function and the pathological changes did not improve 4 weeks after discontinuation of feeding with melamine-contained diet.

Objective To study the effect of nursing intervention on the depression patients and their members. Methods 116 depression patients were randomly divided into two groups, the study group ( n = 59) and the control group (n = 57 ). 59 family members of the study group were selected. Patients of the two groups all accepted the routine therapy and nursing intervention. At the same time, the family members of the study group accepted the family nursing intervention once a week, and the intervention continued for 8 weeks. The curative effects of patients were evaluated by HAMD ( Hamilton Depression Rating Scale) and SDS, and the psychological state of family members were examined by SCL-90 (Symptom Checklist 90). Results Through 8 weeks of nursing intervention, scores of HAMD and SDS of the study group were (13.74±6.34)and (3.82±1.24), respectively, showing a statistical meaning compared to the control group (P <0.05). The scores of somatization, depression and anxiety in SCL-90 were significantly improved in the family members of depression patients in the study group. Conclusions Implementing nursing intervention among the depression patients and their family members can improve the curative effect, facilitate the rehabilitation, and ameliorate the psychological health of family members.

OBJECTIVEThis study attempted to explore the value of combining serum hepatic fibrosis-related markers and ultrasound parameters together on diagnosis of hepatic fibrosis.

METHODSSix serum markers and 8 ultrasound parameters were measured from 100 patients with chronic hepatitis B or cirrhosis. The results of the serum hepatic fibrosis-related markers and ultrasound in disease group were analyzed and compared with the findings of hepatic pathology.

RESULTSBy filtrating,the group of platelet derived growth factor-BB (PDGF-BB) plus hyaluronic acid (HA) plus echo characteristics of liver parenchyma (LPEC) plus length of spleen (SL) had the highest Se and Spe, which were 90.7% and 85.4% respectively.

CONCLUSIONThe advantageous combination of serum markers and ultrasound parameters can significantly improve Se and Spe, which is superior to any single serum index or ultrasound parameter. And it was a better non-invasive method for diagnosing hepatic fibrosis.

The study was aimed to investigate the different prognosis of acute myeloid leukemia (AML) with inv (16). A 13-year-old patient diagnosed as M4Eo presenting with bulky lymphadenopathy was reported, the curative process of patients was presented and the related issues were discussed. The karyotype and inv (16) were detected by conventional cytogeneties and fluorescence in situ hybridization (FISH), respectively, the immunophenotype was detected by flow cytometry. The results showed that conventional cytogenetics and FISH analysis revealed inv (16). Induction therapy included idarubicin and cytarabine. After complete remission, patient received consolidation theray containing high-dose cytarabine (HDAC). FISH analysis revealed poor response of patient to HDAC. It is concluded that bulky lymphadenopathy in AML with inv (16) may be a negative prognostic sign. FISH for inv (16) is specific and constitutes an reliable tool to be used for diagnosis and minimal residual disease (MRD).

OBJECTIVETo understand the state of health of the middle-aged and old males in Jiangsu Province.

METHODSA total number of 3 551 middle-aged and old males aged 46 approximately 69 years were randomly selected from 13 counties of Jiangsu Province. All of them received physical examinations, including laboratory tests of liver and kidney function, sugar and cholesterols, radioimmunoassay of testosterone and free testosterone levels in the serum, and B-ultrasonic examination of the prostate volume and remaining urine. They also underwent inquiries according to the International Index of Erectile Function (IIEF-5) and the questionnaire for PADAM (partial androgen deficiency of the aging male).

RESULTSThe prostate volume differed significantly (P < 0.05), while the testosterone level showed no significant difference in different age groups (P > 0.05). The level of the free testosterone in the serum descended with the increase of age. The incidence of ED and PADAM was also correlated with the increase of age.

CONCLUSIONIn the old and middle-aged population of males, with the increase of age, sexual function decreases, the prostate volume enlarges, and the incidence of ED and PADAM obviously increases (P < 0.001).
