Introduction Violence is defi ned by the WHO as “the intentional use of physical force or power, threatened or actual, against oneself, another person, or against a group or community, which either results in or has a high likelihood of resulting in injury, death, psychological harm, maldevelopment, or deprivation”. Violence can be divided into many types such as physical, psychological, sexual, neglect and economical etc. Violence against women and child is a manifestation of historically unequal power relations between men and women or child due to patriarchy in many countries of the world. Child maltreatment or violence is one of common public health problems in worldwide and psychologically harm in child’s later life. Objective To detect types, percent and some infl uencing factors of violence against child and adolescent among cases, which were involving into forensic psychiatric evaluation procedures. Materials and Methods We are analyzed all archive documents of NCMH, 2000-2014 by retrospective methodology on based ethical approval of NCMH administration (by ordering 2/189 Oct 28, 2015). Results Total 1067 cases of violence against child and adolescent were registered in 2000-2014 years and 84.7 percent of those (n=904) were sexual violence cases. Gender difference was defi ning among sexual violence cases (girls n=885, p<0.000; boys n=19, p<0.000) with statistically signifi cant. Sexual offender can be act his violence in drunken (OR=2.355; p<0.000; CI 95%; 1.601-3.463) or negative relationship between family members (OR=3.723; p<0.000; CI 95%-2.356-5.883) are more infl uenced to sexual violence against child and adolescent. Conclusion Sexual violence is more registered among child and adolescent maltreatment cases. Children and adolescents are more affected into sexual violence likely to have a negative relationship between the family members or offenders have used alcohol.

OBJECTIVE: To compare the polysaccharide contents of Dendrobium officinale in collection periods. METHODS: The contents of polysaccharide and mannose were determined by phenol-sulfuric acid method and HPLC. The ratio of peak area between mannose and glucose was worked out by HPLC. RESULTS: The polysaccharide content of Dendrobium officinale distributed from 26.52% to 46.78%, the mannose content was between 13.36% and 25.25%, and the ratio of peak area between mannose and glucose was 2.48-5.91. CONCLUSION: The polysaccharide contents of Dendrobii officinalis from different sources were diverse, all of which accorded with the standard of Chinese Pharmacopoeia: The content of polysaccharide in Dendrobium officinale from Yunnan province exceeded that from Zhejiang province, and the mannose content in biennial samples were higher than annual samples.

Xanthogranulomatous pyelonephritis (XGP) is an unusual form of chronic pyelonephritis in which the renal parenchyma is destroyed and replaced by lipid-laden foamy macrophages. It usually affects middle-aged women with a history of recurrent urinary tract infection, diabetes, or kidney stones. The inflammatory process is usually diffuse and can extend beyond the kidney. The rare focal forms may simulate primary renal tumours. The preoperative imaging diagnosis may be difficult. We reported five cases of XGP, The findings of ours were recorded including kidney size, shape, contour, the echogenecity of the renal parenchyma, the internal echoes of the dilate collecting system, the presence of perinephric fluid accumulation and obstruction. One of the 5 cases was a male patient, and the other four were female, with a mean age of 53 years. He affected kidneys of the 5 cases swelled in different degrees, and one of them was found with line-like anechoic fluid. Among the 5 cases, one kidney appeared as diffusely reducing of the parenchyma echogenicity, multiple hypoechoic areas, disappearance of corticomedullary differentiation and multiple hyperecho with shadow. A round cystic anechoic lesion was found in one kidney, with internal punctate echo and peripheral fluid. Ultrasonographic finding of 1 case was extremely hypoechoic lesion on the left kidney, protruding from the outline of the kidney, with the partial renal capsule discontinuous, the less clear boundary, and a little blood flow in it. Ultrasonographic demonstration of 2 cases was mild dilatation of the collecting system with irregular wall thickening and internal hypoechogenicity, and 1 case was solid lesion with less clear boundary to the pelvic wall and a small amount of blood flow signal, the another 1 case was showed floccule without internal blood flow. Three cases were caused by chronic obstruction verified by operation, of which one was staghorn calculi, one was poorly differentiated squamous cell carcinoma in the middle part of the ureter, and one was inflammatory stricture of upper ureteral. Through analysis of the above five cases and review of related literature, we explored diagnoses and management of the patients with XGP. Xanthogranulomatous pyelonephritis (XGP) is a rare chronic variant of pyelonephritis characterized by destruction of the renal parenchyma. Combining ultrasonographic features of XGP with clinical recurrent urinary infection and chronic obstruction, XGP can be included in the differentiation. The diagnosis of XGP suspected by ultrasound can be clarified by CT, MRI, contrast-enhanced ultrasound.

Objective: To study the relations between neck/shoulder or low back pain and their daily behavioral habits among middle school students in Shenzhen. Methods: We randomly chose 3 952 students from 10 high schools in Shenzhen to complete the questionnaires. Data was gathered and analyzed, using the IBM SPSS 23.0. Results: Of the 3 952 participants, 20.3% had neck/shoulder pain and 15.2% had low back pain. Among students experienced neck/shoulder pain, female (25.3%), high school (24.5%) and boarding students (24.4%) experienced higher rates of neck/shoulder pain (P<0.05). Female students (17.9%) also had higher rate of low back pain (P<0.05). Results from logistic regression analysis showed that factors as: gender, type of school, taking naps on the desk, staying up late, self-perceived stress from learning, overloading homework, time spent on mobile phone and TV, spending long time on computer etc. were related to the neck/shoulder pain (P<0.05). Factors as: gender, naps on the desk, stay up late, self-perceived stress, overloading homework, time spent on mobile phone and TV etc., were related to low back pain (P<0.05). Conclusion: Neck/shoulder pain and low back pain were both commonly seen while high self-perceived stress, sedentary behaviors and poor sleeping habits were associated with both neck/shoulder and low back pain in high school students in Shenzhen.

Cellular senescence is a biologically irreversible state of cell-growth arrest that occurs following either a replicative or an oncogenic stimulus. This phenomenon occurs as a response to the presence of premalignant cells and appears to be an important anticancer mechanism that keeps these transformed cells at bay. Many exogenous and endogenous triggers for senescence have been recognized to act via genomic or epigenomic pathways. The most common stimulus for senescence is progressive loss of telomeric DNA, which results in the loss of chromosomal stability and eventual unregulated growth and malignancy. Senescence is activated through an interaction between the p16 and p53 tumor-suppressor genes. Senescent cells can be identified in vitro because they express senescence-associated beta-galactosidase, a marker of increased lysosomal activity. Cellular senescence plays an integral role in the prevention and development of both benign and malignant gastrointestinal diseases. The senescence cascade and the cell-cycle checkpoints that dictate the progression and maintenance of senescence are important in all types of gastrointestinal cancers, including pancreatic, liver, gastric, colon, and esophageal cancers. Understanding the pathogenic mechanisms involved in cellular senescence is important for the development of agents targeted toward the treatment of gastrointestinal tumors.

We used ultra-high performance liquid chromatography-mass spectrometry (UPLC/MS) for analyzing and identifying the active components of newborn calf serum (NCS) and fetal bovine serum (FBS). The results demonstrated significant differences in the components between NCS and FBS. FBS appeared to have more complex components than NCS, with mass to ratios (m/z) of the substances of 498, 273 and 448. These substances in FBS may be the main active components to support the proliferation and differentiation of cells.

A new type wound dressing-aFGF/collagen composite sponge was prepared by bovine tendon and aFGF. Its physical function, biocompatibility, and hemocompatibility in particular, were studied for full assurance of its biosafety. The acute toxicity and skin irritation tests of composite sponge of high and low doses were negative. Recalcification test demonstrated that the recalcification time of composite sponge was much longer than that of the control group. Hemolysis test revealed that the composite sponge did not lead to hemolysis. Platelet adhesion test showed that the surface of composite sponge had less platelet adhesion than did the surface of glass, and the composite sponge did not destroy platelets. The results indicate that aFGF/collagen composite sponge has good biocompatibility and possibility for clinical use.

OBJECTIVETo use infrared thermography to take cat cerebral cortical temperature in order to visualize the temperature of its entire cerebral cortex as an image.

METHODSAfter performing craniotomy for exposure of cerebral hemispheres in 52 cats, their cortical temperatures were displayed and analyzed by computerized infrared thermovision.

RESULTSThe temperature distribution of the cerebral cortex was uneven, with a maximum difference of 2.3 degrees C among different cortical areas. The temperature in the cortical anterior-inferior area (including the Ant. Ectosylvian, the lower section of Mid. Ectosylvian and the Ant. Sylvian) was higher compared to the temperature in the posterior-super-parts (Post. Suprasylvian, Mid. Suprasylvian, Post. Lateral and Ant. Lateral). Locations with higher or lower temperatures showed little change within three days after craniotomy, and the cortical temperature held steady.

CONCLUSIONThe use of cortical infrared thermo-images for display of cat cortical temperature is possible and has many advantages over traditional methods. This new neuroimaging method has a practical value in neurological research.

Fallen leaves of Ficus altissima, F. virens, F. benjamina, F. fistulosa and F. semicordata, were collected in Chiang Mai Province in northern Thailand and examined for fungi. Eighty taxa were identified, comprising 56 anamorphic taxa, 23 ascomycetes and 1 basidiomycete. Common fungal species occurring on five host species with high frequency of occurrence were Beltraniella nilgirica, Lasiodiplodia theobromae, Ophioceras leptosporum, Periconia byssoides and Septonema harknessi. Colletotrichum and Stachybotrys were also common genera. The leaves of different Ficus species supported diverse fungal taxa, and the fungal assemblages on the different hosts showed varying overlap. The fungal diversity of saprobes at the host species level is discussed.
