Objective To solve the problem of erectile dysfunction in clinical forensic medicine investigation by using the nocturnal penile tumescence (NPT) testing. Method 13 cases who complained erectile dysfunction after trauma were studied by using RIGISCAN PLUS SYSTEM. Results In 13 cases, the results of NPT testing showed that the erectile function was normal in 3 cases, slight dropping in 5 cases, medium dropping in 2 cases, and completely losing in 3 cases. In 5 cases which were serious erectile dysfunction as tested by IIEF, the NPT showed that the erectile function was normal in 1 case, slight dropping in 1 case, medium dropping in 1 cases, and losing completely in 2 cases. Conclusion The nocturnal penile tumescence testing can solve the problem of erectile dysfunction in forensic medicine investigation including the estimatieon of the severity of injury, labor ability assessment and some related questions.

Objective It aims to investigate the relationships among the categories of Comprehensive Version for Stroke as described in the International Classiifcation of Functioning, Disability and Health (ICF) Core Set, and to provide new supports for Judicial Appraisal of functioning in stroke by ICF functioning mapping.Methods The variables of 59 categories of ICF assessment scale and the samples of 106 persons’ are selected and used in the least absolute shrinkage and selection operator (LASSO) for mining dependencies among those variables. The graphical modeling and analyzing with the software Gephi provides a visual map of the correlations among those classiifcations. Results 59 interconnected categories which organized into the functioning mapping. b340, b735, b175 and b152 are centrally positioned categories because of their high correlation.Conclusion Functioning mapping by graphical modeling can reveal complex relational structures embedded in functioning classiifcations, which provides the support for using ICF to appraisal stroke.

OBJECTIVEWe studied the licorice provenance rule under the manual simulative water stress conditions, discussed geographical variation pattern and the ecology mechanism and laid the theoretical basis for the licorice seed regionalization and the seed allocation.

METHODOn the spot we investigated and collected seed materials. Setting up water potential gradient by PEG, we observed the seed germination characteristic through the experiment of indoor germination.

RESULTThe sensitivity of various provenance seed germinative energy show quite remarkable difference for water potential reducing. Along with geographic longitude increasing, the seed germinates variation sensitivity increasing gradually to the water stress. The results of climatic factors' correlation analysis indicated that provenance seed germinate energy to the water stress is sensitive, in which the annual average temperature is low and annual precipitation is abundant. But it is insensitive in which the annual precipitation is little, the annual average temperature, average temperature in July and the annual average ground temperature is high.

CONCLUSIONUnder the water stress condition the licorice provenance seed germination characteristic exists remarkable geographical variation. Geographical variation is the result of natural selection.

The article is study about principle of lower extremities on Guides to the Evaluation of Permanent Impairment. We reviewed the latest concept in lower extremities evaluation of GEPI, such as regional impairment, diagnosis based impairment and grade modifier. We also introduced maximum medical improvement and conversion from lower extremities impairment to whole person impairment. To provide advice for construction of disability evaluation system in China.

Objective:To compare the clinical efficacy, prognosis and complications between intravenous chemotherapy (IVC) combined with intra-arterial chemotherapy (IAC) and single IAC in the treatment of children retinoblastoma (RB).Methods:A cohort study was performed.A 4-year follow-up of 300 children (352 eyes) with intraocular RB enrolled in the Children's Hospital Affiliated of Zhengzhou University from June 2015 to June 2019 was conducted.According to the different treatment methods, the children were divided into IAC group (140 cases, 160 eyes) treated with IAC combined with local laser photocoagulation/cryotherapy and IVC+ IAC group (160 cases, 192 eyes) receiving IVC combined with IAC treatment.The clinical efficacy (eye salvage rate), survival and complication incidence of the two groups were compared.The survival analysis was performed by Kaplan-Meier method.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Children's Hospital Affiliated of Zhengzhou University (No.20150503). Written informed consent was obtained from custodians of each child prior to their entering into the cohort.Results:All of the children were followed up for 2-60 months.Within the follow-up, the eye retention rate of the IAC group and IVC+ IAC group was 85.62%(137/160) and 81.21%(154/192) respectively, without statistically significant difference ( P>0.05). The recurrence rate and metastasis rate of IAC group were 18.75%(30/160) and 8.57%(12/140), which were significantly higher than 10.94%(21/192) and 3.13%(5/160) of IVC+ IAC group ( χ2=4.299, P=0.038; χ2=4.143, P=0.042). There was no significant difference in one-year survival rate between the two groups ( χ2=1.766, P=0.184), but the overall survival rate of IVC+ IAC group was 95.00%(152/160), significantly higher than 88.57%(124/140) of IAC group ( χ2=4.193, P=0.041). Kaplan-Meier analysis showed that the overall recurrence-free, metastasis-free and survival rate of IVC+ IAC group were better than those of IAC group, and the differences were statistically significant (all at P<0.05). There was no significant difference in the incidence of eyelid edema and/or ptosis, fundus hemorrhage, enophthalmos and cataract between the two groups (all at P>0.05). The incidence of myelosuppression was 32.14%(45/140) in IAC group, significantly lower than 43.75%(70/160) of IVC+ IAC group ( χ2=4.255, P=0.039). Conclusions:Compared with single IAC treatment, IVC combined with IAC can reduce the metastasis rate, recurrence rate in RB child patient and improve the survival rate, but it is with relatively high incidence of systemic complications.

The article is study about range of motion on lower extremities on Guides to the Evaluation of Permanent Impairment. We reviewed the latest range of motion concept about lower extremities evaluation of GEPI. We also introduced measurement and procedure of range of motion evaluation.
