Objective To investigate the MRI characteristics of the tumor of optic pathway and damage degree of visual function. Methods Analysis of 119 cases surgically and pathologically proved tumor suffering from optic pathway was carried out retrospectively. The patients included:36 ones with tumors in anterior segment of optic pathway,70 ones in middle segment of optic pathway,and 13 ones in posterior segment of optic pathway. The MRI examination series were transverse T 1WI SE,transverse and coronal T 2WI TSE,coronal T 2WI SPIR,and transverse,sagittal,coronal T 1WI SE after Gd DTPA enhancement. Results The tumors of optic pathway included:the primary tumors of the optic pathway and the tumors of any other part of the body which invaded the optic pathway. There was a special MRI feature on the each tumor suffering from optic pathway,but the pituitary adenoma which affects visual function was the most common tumor. Conclusion MRI is an effective method in the diagnosis of optic pathway tumor.

Results The mean operative time was 110 min and the mean blood loss 300 ml.The biggest stone was 6.5 cm?5.0 cm?3.0 cm and in one case the number of stones amounted to 1 400. Postoperative KUB showed no residual stones and postoperative IVU indicated normal renal function.All patients have been followed up for 1～3 years and have been free of stone. Conclusions The procedure has the advantages of no need of pedicle renalis occlusion,less bleeding,a clear operation field,easy staghorn calculi removal and the avoidance of renal hilum outlet obstruction.

Objective To observe the features of the manifestations of fundus fluorescein angiography (FFA) in multiple sclerosis (MS) and their value in clinical diagnosis. Methods The clinical data of 42 patients (84 eyes) with MS diagnosed by magnetic resonance imaging (MRI) and examination of cerebrospinal fluid (CSF) were retrospectively analyzed. The clinical data included visual acuity, ocular fundus examined by direct ophthalmoscope after mydriasis, FFA, visual field, CSF,visual evoked potential (VEP) and MRI examination. Results In 42 patients (84 eyes),the positive detectable rate of examination of direct ophthalmoscope, CSF, visual field, VEP, and MRI was 36.9%, 21.4%, (71.4%, and) 83.3% respectively. Abnormal results of FFA were found in 44 eyes (52.38%), including papillitis in 4 eyes (4.76%)at the early stage with extended physiological scotoma and central scotoma; neuroretinitis in 7 eyes (8.33%)at the medium stage with central or para- central scotoma; optic atrophy in 33 eyes(39.29%) at the late stage with centripetal constriction and even tubular visual field. Conclusion The main angiographic features of MS are papillitis, neuroretinitis and optic atrophy. The manifestations of FFA combined with the results of examination of CSF,visual field, VEP and MRI is helpful for comprehensive and exact diagnosis of MS.

Objective To establish the model of abdominal heterotopic heart transplantation and grope steady operation methods.Methods The heart transplantation was performed in the control group(group A) and experiment group(group B) with 30 rats in each group.Another 30 animals not performed the operation were as the blank group(group C).During the procurement of the donor heart saline solution containing heparitin was injected into the inferior vena cava of liver.At the same time abdominal aorta was transected.Then heart was perfused until it stopped.The activity of superoxide dismutase(SOD) and content of malondialdehyde(MDA) in blood was measured after transplantation.Results The total perfusion time of the graft was shortened within 2 min and hot ischemia time was shortened within 25 s in the group B.The activity of SOD and content of MDA between two groups was significantly different(P<0.05).Conclusion The perfusing method improved with new technique is quicker and more effective than the traditional one and results in the successful rate improvement.

Objectives To compare the co-infection statues of HSV, HBV and HCV in patients with STD and HIV infection for providing evidence of developing prevention and control strategies. Methods Serum samples confirmed to be infected with HIV/AIDS by Western blot, and serum samples of patients with STDs (syphilis, gonorrhoea and chlamydial infection) were tested for HSV2-IgG, HSV2-IgM, HBsAg and HCV-IgG by ELISA. The detection levels were compared between the two groups. Results Out of 76 specimens in STD group, HSV2-IgG was detected in 24 specimens (31.58%), HSV2-IgM in one specimen (1.32%), HBsAg positive in 8 (10.53%), and HCV antibody positive in 4 (1.32%). In 14 specimens of HIV/AIDS group, HSV2-IgG were detected in 7 (50.00%); HSV2-IgM in 5 (35.71%);8 (578.14%) were positive for HBsAg and 3 (21.43%) for HCV. In a total of 90 specimens, both HSV and HBV were detected in 6 specimens, both HSV-IgM and HBV in 2, and the four above-mentioned antibodies in 2. The infection rates of HSV, HBV and HCV were significantly higher in HIV-infected specimens than those in the STD specimens (P

Oral feeding of water cannot be accomplished in some critical patients due to coma, mouth-breathing or long-term indwelling of gastric tube, causing dry mouth which results in oral pain, ulcer, or infection, aggravating patients' discomfort and even affecting the prognosis. To solve this problem, the medical staff of the First Hospital of Jiaxing developed a novel oral humidifier and obtained the National Utility Model Patent of China (ZL 2019 2 0066979.0). The oral humidifier consists of a spraying device and a fixation device. The spraying device is a spraying housing with a water tank, and a spraying port where nanometer water mist can be emitted. The spraying housing is also equipped with a flashlight with a switch, and a schematic diagram of pupil size, which can be used to assess the pupil size conveniently. The fixing device is composed of a fixing frame, an adjustable rod and a clamp. The two ends of the adjustable rod are connected to the fixing frame and the clamp respectively, and can be adjusted to proper shape. The spraying housing can be placed on the fixing frame and installed on the bed and adjusted to the proper position quickly. This novel oral humidifier is a simple device which combines a spraying system with a pupil evaluation tool, implying significant clinical application in improving the convenience of nursing and alleviating dry mouth of critical patients.

At the beginning of the founding of People’s Republic of China, infectious diseases, such as smallpox, plague, cholera, dysentery, typhoid, measles, diphtheria, pertussis, meningitis, mumps, schistosomiasis, Kala Azar, hemorrhagic fever, leptospirosis, encephalitis B, typhus, malaria, Kala Azar, leprosy, scarlet fever and pinkeye, remained as epidemic in the country and endangered people’s health. During the past 70 years, the Chinese government spent huge efforts in infectious disease prevention and treatment by promulgating and implementing series of relative policies, laws and strategies, and also encouraged all Chinese people to participate in. The achievements of these efforts in controlling infectious disease epidemic were extremely successful. Today, the outbreaks and epidemic of infectious diseases in China were rarely happened with the rapid decreases in incidence and mortality rates of all notifiable infectious diseases. Smallpox was eradicated, and polio, filariasis, leprosy and neonatal tetanus were nearly eradicated. In addition, the incidence rates of vaccine-preventable diseases, i.e. measles, diphtheria, pertussis, meningitis, encephalitis B, hepatitis A, mumps, rubella, tuberculosis, were dramatically decreased and remained at relatively low levels for years. The incidence and prevalence rates of hepatitis B infection in Children decreased significantly and reached the phase objectives. Moreover, incidence rates of natural iatrogenic infectious diseases, i.e. diarrhea, typhoid and other intestinal infectious diseases, leptospirosis and schistosomiasis, and vectorborne diseases, i.e. typhus, malaria, Kala Azar, reached the lowest and some even closed to be eliminated in China. In general, infectious diseases dropped to the tenth from the top one leading cause of all deaths, which means that the achievement of Chinese infectious disease prevention and treatment strategies contributed tremendously in improving Chinese people’s health status and life expectancy.

Objective To analyze the indication,ways,therapeutic effect,dose prescription and complication of skull base tumor treated by Gamma Knife.Methods Clinical data,including general information,method of treatment and therapeutic effect of 278 benign skull base tumors treated by Gamma Knife were studied retrospectively.Results All patients were followed up for at least 2 years.The clinical conditions improved significantly in 130 patients,remained stable in 125 patients,and worsened in 23 patients.The 5 years progression-free survival rate was 89.5%(249/278)by Kaplan-Meier analysis.The results of Log-rank analysis revealed that better results appeared in patients with smaller tumors.≤3 cm compared with those tumors＞3 am(X2=5.41,P=0.02),and in patients experiencing tumor resection compared with those without history of su~ery respectively(X2=3.96,P=0.047).10 of the 11 cases with tumors＞3 cm who were treated by volume-staged prescription achieved local tumor control.Brain edema occurred in 3 patients,apoplexy of tumor in 1 patient,hydrocephalus in 3 patents,dysfunction of cranial nerves in 12 patients.Conclusion For skull base tumor,Gamma Knife is a major choice,with low risk and maybe an alternative for those small tumors.For those residues after craniotomy,Gamma Knife maybe an auxiliary treatment,and it can be cautiously applied in those with large tumors who cannot tolerate surgery for various reasons.
