Objective: Our aim was to investigate whether the immune RNA (iRNA) can inhibit the endotoxin-induced uveitis (EIU). Methods: The EIU was induced by injecting endotoxin of E.Coli into rats hypodermically. iRNA was abstracted from the livers and spleens of the rabbits which had been injected by E.Coli six times. The iRNA was introduced intraperitoneally into the rats both at half an hour and 3 hours after the injection of endotoxin. The effect of iRNA was evaluated by protein determination and cell count in aqueous houmer(AH). Results: The appearance of EIU in the iRNA treated rats was delayed, about 3 hours later than the rats received only endotoxin injection. The AH protein decreased by 58.34% and cellular infiltration decreased by 27.62% in iRNA treated group at the 24 hours. Conclusion: The iRNA may partly prevent the development of EIU and significantly reduce the severity of EIU.

Objective To explore the side effects of pemetrexed in the maintenane therapy of nonsmall-cell lung cancer (NSCLC) at advanced stage and summarize the nursing measures. Methods Fifty-one NSCLC patients were treated maintenance therapy by pemetrexed. The side effects were observed and corresponding nursing measures were taken. Results The side effects included bone marrow depression of 33 cases, adverse reactions in gastrointestinal tract of 14 cases, and skin rashes of 4 cases, all at the degree of I-II. All of them were alleviated after active treatments. Conclusion Such nursing measures as close of side effects and careful nursing to the NSCLC patients treated with maintenance therapy with temetrexed are main measures for the success of treatment.

[Summary] According to the cutpoint of plasma triglycerides concentration ≥ 1.7 mmol/L,waist circumference ≥85 cm in men or ≥80 cm in women,459 patiens with type 2 diabetes mellitus were divided into four groups:normal waist circumference and triglycerides,normal waist circumference and hypertriglyceridemia,abdominal obesity and normal triglycerides,and hypertriglyceridemic-waist (HTWC) group.The results showed that body mass index,waist circumference,systolic blood pressure,triglycerides,microalbuminuria,and homeostasis model assessment insulin resistance index (HOMA-IR) in HTWC group were higher than those in non-HTWC groups (all P＜0.01),as well as higher diabetic nephropathy incidence (P＜0.05).Multiple logistic regression analysis revealed that HTWC was an independent risk factor of diabetic nephropathy (OR =2.070,95 ％ CI 1.195-3.586).

Objective To investigate the clinical value of bone scintigraphy for the diagnosis of synovitis, acne, pustulosis, hyperostosis and osteitis (SAPHO) syndrome. Methods The characteristics of SAPHO syndrome on 99Tcm-MDP imaging of 8 cases were retrospectively analyzed. Results The 99TcmMDP bone scan was positive for all patients. Seven cases were found lesions in the costoclavicular region, 3cases involved with unilateral sacroiliac joint, 2 cases involved with spine and 1 patient with extremity. Four lesions were found without relevant clinical symptoms. Conclusion Bone scintigraphy is useful for the diagnosis of SAPHO syndrome, especially for those lesions with no clinical symptoms.

Abstract: Objective　To explore the value of real-time shear wave elastography in evaluating the severity of liver fibrosis in hepatitis B, and to analyze the factors that affecting its accuracy. Methods　A total of 196 chronic hepatitis B patients, who admitted to the Third Affiliated Hospital of Chengdu Medical College from February 2018 to October 2020, were selected for retrospective analysis. Demographic indicators such as gender, age, body mass index(BMI), and laboratory indicators such as fasting blood glucose, liver function, and blood lipid composition were collected. The patients were detected by real-time shear wave elastography. Taking the pathological test results as the gold standard, the diagnostic value of real-time shear wave elastography in the severity of liver fibrosis in chronic hepatitis B was analyzed, and the comprehensive effect of various factors on the diagnostic accuracy of real-time shear wave elastography was evaluated by Logistic regression analysis. Results　The differences in real-time shear wave elastography of patients with different severity of liver fibrosis in hepatitis B were statistically significant, and F0 grade

?AIM: To discuss the effect of laser exposure on visual acuity and macula.?METHODS: Retrospective and consecutive case series. A retrospective analysis of 11 patients (11 eyes) with laser retinal injury was carried out from January 2014 to June 2015 in Ophthalmology Department of No. 474 Hospital of Chinese PLA. All individuals underwent visual acuity, best corrected visual acuity ( BCVA ) , and spectral-domain optical coherence tomography ( SD-OCT) for macular at first visit, and fundus fluorescein angiography ( FFA ) , visual field, and multifocal electroretinogram ( mf ERG ) were perform if necessary. Symptomatic therapies, supportive therapies and pars plana vitrectomy ( PPV ) were performed depended on the patient’s condition. The patients were followed-up at 1, 3 and 6mo after the first visit, and patients were undertaken visual acuity, BCVA, macular SD-OCT and so on.?RESULTS: Eight patients ( 73%) were under 18 years old and all patients were young males, who were injured by laser pointers when playing. Three patients ( 27%) over 18 years old were injured accidentally at work. Ten (91%) patients’ BCVA were ≤0. 3, while one ( 9%) patient’s BCVA was higher ≥0. 3. Full-thickness macular holes ( the diameter 224-519 μm ) were detected in 10 patients (91%), while sub-foveal RPE changes and IS/OS injury in 1 patient ( 9%) . Macular hole with traction or cystoid edema in 6 eyes (55%) were received PPV, while the other 5 eyes ( 4 eyes with stable macular hole and 1 eyes with RPE injury ) received conservative treatment. Macular hole closed successfully in 1 eye ( 17%) after PPV, while macular hole in the other 5 eyes ( 83%) were stable after PPV of which the cystoid edema faded. The 4 patients with macular hole and 1 patient with RPE injury were stable during follow-up period. However, the BCVA in all patients had no significant improvement at end.?CONCLUSION: Exposure to laser devices could lead to severe macula injury that could reduce central vision, which is permanent.

To study the genetic stability of Panax quinquefolium after introduced into China for 30 years, the samples of P. quinquefolium from 14 regions of China were studied. RAPD molecular marker technology was applied in this research, and POPGEN32 data analysis and NTSYS2. 10 cluster diagram were used to analyze the data. The results showed that there are abundant genetic diversity in the ginseng samples. There were 81 polymorphic bands based on the 13 random primers. The polymorphism was 83.51%, the effective number of alleles (N(e)) was 1.456 7; Nei's gene diversity index (H) was 0.274 8; Shannon's diversity index (H(o)) was 0.419 4. The clustering analyses indicated that P. quinquefolium and P. ginseng were classified into two obvious groups, especially, it was also found that the P. quinquefolium could be divided into two obvious groups based on whether the P. ginseng was cultivated in the same region or not, but it was thought that there was not genetically a qualitative difference. Thus it suggests that a good breeding field should be established in Jilin Province of China for the germplasm purification.
