OBJECTIVE: To explore a simple speedy specific and sensitive method to detect specific IgM (sIgM) and IgG (sIgG) antibodies of hemorrhagic fever with renal syndrome (HFRS),and to study the therapeutic effects of integrated traditional Chinese and western medicine on HFRS. METHODS: The serum of 559 patients with HFRS were tested with colloidal gold immuno-dot assay (CGIDA) for sIgM and sIgG antibodies and compared with enzyme linked immunosorbent assay (ELISA) or indirect fluorescent antibody test (IFAT). One hundred and one patients with HFRS were randomized into treatment group (n=50),treated with Kuhuang Injection, Shenmai Injection and Huangqi Liquid) and control group (n=51),treated with Ribarvirin and Ganlixin Injection). RESULTS: The positive rate of sIgM detected with CGIDA was 70.8% and the positive rate of sIgG detected with CGIDA was 87.5%. The days for fever decline, symptoms alleviation and sign relief between the treatment group and control group were similar (P>0.05). The days for recovery of kidney function in the control group was less than that in the treatment group (P<0.01). The rate of crossing shock stage in the treatment group was higher than that of the control group (P<0.01). CONCLUSION: CGIDA was more simple, speedy, specific and sensitive than ELISA or IFAT in detecting the sIgM or sIgG antibodies in serum of patients with HFRS. Although the sensitivity of CGIDA was lower than that of ELISA the CGIDA had no false positive reaction the sensitivity of CGIDA was higher than that of IFAT on detecting IgG. The effect of the treatment group was similar to that of the control group. But the crossing shock stage rate in the treatment group was higher than that of the control group while the control group was better than the treatment group in recovering the kidney function.

ObjectiveTo study the effect of negative pressure suction during laser in situ keratomileusis (LASIK) on rabbit retinal structure.Methods32 New Zealand white rabbits were randomly divided into normal control, experimental control, negative suction 45 seconds and negative suction 3 minutes groups. Experimental control groups were treated only using eximer laser. In negative suction groups, rabbit eyes were suction for 45 seconds or 3 minutes by negative pressure generator. The tissues of optic nerve and retina both after negative pressure suction and of normal rabbit eyes were examined with electron and light microscope 0, 7, 14, 28 days after operation. ResultsThere was no change in the tissues of optic nerve and retina between normal control and experimental control. After the negative pressure suction for 45 s, the optic nerve and retinal cells changed lightly at different time point. After the negative pressure suction for 3 min, the optic nerve fibers and retinal cells changed sharply during postoperative instant to 14th days, which can be recovered until 28 days after operation.ConclusionUltrastructural changes of retina and optic nerve may be induced by acute intraocular pressure elevation caused by negative pressure suction during LASIK.

Objective Adhesion or too highly located folds upper eyelid and even hlepharoptosis are common complications after double eyelid operation. The method was designed to correct these de-formities. Methods The incision of upper eyelid was designed under the scar. Skin was resected between the former and the new double line, if there was excessive skin. Completely relieve the adhesion until nor-mal tissue was exposed. Expose lateral extension of retro-orbicularis oculi fat pad. An upper pedicle fat flap was formed after cutting tissues off along bilateral borders. Appropriately and transversely cutting lateral portion of the pedicle made it rotate inside downward with enough blood supply. The fat flap was fixed with released orbital fat and the lower edge of fat flat fixed with upper border of supratarsal to restorate the volume. For severe condition, fat granule injection could be used after the skin was sutured. Results 42 cases (80 eyes) were treated in the past two years. The deformities of 32 cases were corrected by the application of retro-orbicularis oculi fat pad. Fat granule injection was applied for the other 10 pa-tients meanwhile. 30 cases (60 eyes) were followed up for 6 to 24 months. The results were satisfactory. Conclusion The methods are performed easily and the results are satisfied. It is worth of recommenda-tion.

Objective To investigate the dynamic changes and analyze the influencing factors of quality of life (QOL) among adult patients undergoing hematopoietic stem cell transplantation (HSCT). Methods Totally 143 HSCT patients were investigated by the common questionnaire, the Perceived Social Support Scale (PSSS) and the Functional Assessment in Cancer Therapy—Bone Marrow Transplant (FACT-BMT) before checked in the purification bin,1 month post transplantation and 3 months post transplantation. Results The QOL were different among different time points of HSCT patients (P<0.05). Multiple factors analysis showed that the factors before checked in the purification bin including social support (OR=4.480, P=0.019), residence (OR=3.167, P=0.036) and disease diagnosis (OR=0.036, P=0.042). The factors 1 month post transplantation included social support (OR=3.573, P=0.018), whether or not the platelets were reconstructed during storage (OR=2.735, P=0.018) and whether there were transplant related complications (OR=0.214, P=0.016). The factors 3 month post transplantation included social support (OR=9.639, P<0.01) and whether there were transplant related complications (OR=0.167, P=0.003). Conclusions The QOL was low among HSCT patients, and it dynamically changed at different points. Social support is the only sustainable influencing factor of quality of life. This prompts us that we should pay abundant attention on social support and use it to improve the QOL of HSCT patients.

Objective To search for independent predictive factors of diabetic kidney disease(DKD)in patients with type 2 diabetes mellitus(T2DM),construct and validate an optional machine learning(ML)model for the risk of DKD.Methods A total of 528 patients with T2DM,hospitalized in the Endocrinology Department of Chengde Central Hospital from October 2019 to September 2020,were selected as the study objects,and patients were randomly divided into a training set(370 cases),and a validation set(158 cases).The training set was divided into the DKD group(89 cases)and the non-DKD group(281 cases)according to whether DKD existed.The general data and diagnostic examination of patients were performed by univariate analysis,in which variables with statistical differences were used to screen the best predictors by least absolute shrinkage and selection operator(LASSO)regression analysis.The best predictors were used to establish eight ML algorithms by three cross-validation methods,including Logistic regression(LR),K-nearest neighbor(KNN),support vector machine(SVM),decision tree(DT),random forest(RF),naive Bayes(NB),artificial neural network(ANN),and extreme gradient lift(XGBoost).The optimal prediction model was selected by receiver operating characteristic(ROC)curve,Delong test and GiViTI calibration curve.Decision curve analysis(DCA)was used to evaluate the clinical practicability of the model.Results Age,alanine aminotransferase,creatinine,triglyceride,cystatin C,25-hydroxy vitamin D and monocyte count were independent predictive factors of DKD.Eight ML models were established based on the above 7 predictors,and the ANN model performed best in the 8 ML models.The GiViTiI calibration curve indicated that the model had good accuracy(P＞0.05),and the DCA showed that the prediction model curve had clinical practical value in the threshold probability range of 0.027-0.612.Conclusion In this study,the ANN model constructed in this study to predict the risk of DKD is helpful for early discrimination of high-risk T2DM patients with DKD.

OBJECTIVE: To explore the clinical features of acute urine retention (AUR) ocurring in patients with benign prostate hyperplasia (BPH). METHODS: Clinical data from 548 patients diagnosed with BPH were retrospectively studied, and the clinical parameters of these patients with or without AUR were analyzed by statistical methods. RESULTS: Development of AUR was found in 164 patients (29.9%). Patients' age, IPSS, maximum flow rate (Q(max)), residual urine volume, prostate volume, transition zone volume, prostate-specific antigen (PSA) density, total PSA (tPSA) and free PSA (fPSA) including the ratio of free to total PSA(f/tPSA) were significantly different in the 2 groups (P<0.05), while there were no significant differences in the disease duration and transition zone index between the 2 groups (P>0.05). Multivariate logistic regression analysis showed that IPSS score, residual urine volume, tPSA, and Q(max) were risk factors for predicting the development of AUR. CONCLUSION BPH patient's age, IPSS, Q(max), residual urine volume, prostate volume, transition zone volume, tPSA and fPSA, and PSA density all influence the occurrence of AUR, in which symptom severity, residual urine volume, total PSA and Q(max) are the principal risk factors for prognosing AUR.

Objective Using Wisconsin Stone Quality of Life questionnaire (WISQOL) to compare standard percutaneous nephrolithotomy(PCNL) and tubeless PCNL.Methods From January 2017 to June 2017,patients who met the criteria (no urinary tract infection,stones between 1-3 cm,hydronephrosis larger than 3cm,renal cortex thickness ＞ 2 cm and without serious heart,lung,liver and kidney dysfunction and coagulation dysfunction) and underwent PCNL were prospectively enrolled and randomized into 2 groups,standard PCNL group and tubeless PCNL group.Diclofenac sodium suppositories were used to relieve pain in all patients with obvious pain.The quality of life of these patients were estimated and compared by using WISQOL.Safety and efficacy were also estimated.Result At the end of the study,a total of 50 patients were included in the analysis.There were 24 patients in the standard PCNL group and 26 patients in the tubeless PCNL group.There were 9 male patients in the standard PCNL group and 17 male patients in the tubeless PCNL group.There was no significant difference in gender between the two groups.The differences between the standard PCNL group and tubeless PCNL group in mean age (yrs.) [(53.21 ±13.35) vs.(51.1 ± 11.5),P =0.55],stone diameter (mm) [(18.46 ± 5.58) vs.(18.75 ± 5.39),P =0.85],stone-free rate (23/24 vs.24/26,P =0.60),mean hemoglobin decline (g/L) [(11.87 ± 9.20)vs.(10.43 ± 8.49),P =0.56] were not significant.Mean dosage of acesodyne(pcs) in tubeless PCNL group (4.07 ± 1.49) was significantly less than that in standard PCNL group (7.54 ± 2.23).There were no patient need transfusion or postoperative fever management.The influence of perioperative quality of life of patients treated with tubeless PCNL is significantly better than those treated with standard PCNL in 16 items which includ energy,sleep,work and family,physical symptoms,concerns related to intimacy and travel,and general emotional well-being.Conclusion Tubeless PCNL can improve patients' quality of life compared with standard PCNL.

Objective? To explore the effects of the problem-oriented intervention model on major nursing issues, self-care behavior and illness perception in elderly patients with type 2 diabetes. Methods? Totally 112 elderly patients with type 2 diabetes admitted in the First Hospital of Jiaxing from September 2016 to September 2017 were selected by convenient sampling and divided into the control group (n=56) and the observation group (n=56) based on the time of admission. Patients in the control group received conventional nursing care, while patients in the observation group received conventional nursing care in addition to problem-oriented nursing interventions. The Omaha Problem Classification Scheme was used to evaluate the nursing issues in the two groups, and the Chinese version of Summary of Diabetes Self-Care Activities (SDSCA) and the Brief Illness Perception Questionnaire (BIPQ) were used to evaluate the intervention effects between the two groups. Results? After 6 months, the resolution rate of major nursing issues in the observation group was 82.93% (68/82), while that in the control group was 63.16% (48/76); (χ2=7.898, P＜ 0.05). The self-care behavior and illness perception in the observation group totaled (27.33±7.36) and (38.49±5.76), respectively, both higher than that in the control group (t=5.180, 7.201; P＜ 0.01). Conclusions? The problem-oriented nursing intervention model can effectively enhance the self-care ability and illness perception in elderly patients with type 2 diabetes.
