Objective To discuss the clinical characteristics and treatment methods of lumbar disc herniation in adolescent and to in-crease the awareness of lumbar disc herniation among orthopedists.Methods Retrospectively reviewed the clinical data of 201 adolescent pa-tients(aged 20 years or less)with lumbar disc herniation who were admitted in General Hospital of Shenyang Military Area Command from January 2001 to December 2010.Analyzed the clinical characteristics and treatment methods,and compared the VAS score and ODI score be-fore operation,one week after operation and at the last follow up.Meanwhile,the complications were observed and compared.Results Among the 201 patients,187 patients(93.0%)presented with low back pain with or without radiating pain,20 patients(10.0%)presented with leg pain for the first symptom.There were only 97 patients(48.3%)were diagnosed with lumbar disc herniation for their first diagnosis in other hospital.Totally 70 patients(34.8%)had a history of trauma before the onset.The most common segments were L4 /L5 (101 cases,50.2%) and L5 /S1 (70 cases,34.8%).There were 140 patients treated by microendoscopy discectomy(MED),25 patients treated by percutaneous endoscopic lumbar discectomy(PELD),and 36 patients treated by open lumbar discectomy(OLD).All the patients were followed up for more than 12 months with averagely followed up for(22.9 ±11.7)months.There was significant improvement one week after operation and at the last follow up compared with the preoperative VAS score and ODI score,and the differences were statistically significant(P <0.05).The rate of postoperative complications was 3.6%,4.0%,8.3% in patients with MED,PELD and OLD respectively.Conclusion Diagnosis of LDH in adolescent is usually delayed.Increase the awareness of lumbar disc herniation could help orthopedists to get a exact medical history,per-form a directed physical examination,and order appropriate imaging studies.Minimally invasive surgery is an effective method to treat lumbar disc herniation in adolescent.

Objective　To analyze the survival status and influencing factors among HIV/AIDS transmitted through homosexual contact from 2004 to 2022 in Nan'an District, Chongqing, China. Methods　HIV infected/AIDS patients transmitted through homosexual contact in Nan'an District, Chongqing from 2004 to 2022 were selected for analysis. The survival rate was calculated using the life table method, the median survival time was calculated using the Kaplan-Meier method, and the survival curve was plotted. The Cox regression model was performed to identify factors influencing survival. Results　A total of 3 110 subjects were included in the study, of which 1 199 individuals (38.55%) were transmitted through homosexual contact. The majority of patients were under 30 years old (694, 57.88%), unmarried (917, 76.48%), and had a higher education level of college or above (724, 60.38%), mainly belonging to the Han ethnicity (1 160, 96.75%). Students accounted for 10.43% of occupational status. The majority of patients were initially diagnosed with HIV (1 104, 92.08%), with 71.45% having a CD4+T lymphocyte count >350 cells/μL at the time of initial testing. The primary source of samples was from testing and consultation (52.88%), and the vast majority (93.16%) underwent antiviral treatment. The median survival time for patients transmitted through homosexual contact was 191.45 months, which was higher than 158.37 months of patients transmitted through other routes, demonstrating statistical significance (P<0.001). Multivariate analysis showed that among patients transmitted through homosexual contact, those with CD4+T lymphocyte count≤200 cells/μL had a higher risk of death compared to those with CD4+ T lymphocyte count>350 cells/μL. HIV infected/AIDS patients who did not receive antiviral treatment also had a higher risk of death. Conclusions　From 2004 to 2022, the reported incidence level of HIV/AIDS in Nan'an District showed an overall upward trend, with a slight decrease influenced by respiratory infectious diseases.The risk of death for individuals infected through same-sex transmission routes had not yet been found to be significantly lower than that of other transmission routes, which may be influenced by the late diagnosis time and short follow-up time of individuals infected through same-sex transmission routes.

On account of the dense cuticles of the fresh stem and the light, hard and pliable texture of the dried stem, Dendrobii Caulis is difficult to dry or pulverize. So, it is very important to the ancient doctors that Dendrobii Caulis should be properly treated and applied to keep or evoke its medicinal effects. The current textual research results about the preliminary processing, processing and usage methods of Dendrobii Caulis showed that: (1) In history the clinical use of fresh or processed Dendrobii Caulis as teas and tinctures were very common. (2) Its roots and rhizomes would be removed before using. (3) Some ancillary approaches were applied to shorten drying times, such as rinsing with boiling mulberry-ash soup, washing or soaking with liquor, mixing with rice pulp and then basking, etc. (4) According to the ancients knowledge, the sufficient pulverization, by means of slicing, rasping, hitting or pestling techniques, was necessary for Dendrobii Caulis to take its effects. (5) The heat processing methods for Dendrobii Caulis included stir-baking, stir-frying, steaming, decocting and stewing techniques, usually with liquor as an auxiliary material. Among above mentioned, steaming by pretreating with liquor was most commonly used, and this scheme was colorfully drawn in Bu Yi Lei Gong Pao Zhi Bian Lan (Ming Dynasty, 1591 CE) ; moreover, decocting in advance or long-time simmering so as to prepare paste products were recommended in the Qing Dynasty. (6) Some different processing programs involving stir-baking with grit, air-tightly baking with ondol (Kangs), fumigating with sulfur, which appeared in modern times and brought attractive outward appearance of the drug, went against ancients original intentions of ensuring drug efficacy.

Three days after interference, all experimental animals were executed. HE staining was used to evaluate morphologic change of the retina, immunohisochemical staining and western-blot tests for identifying and quantifying the distinct expression of Caspase-3 and GAP-43 among the groups.
RESULTS: Compared with the normal group and negative control group, retinal morphology of different concentrations of each Daidzein treatment group and positive control group was more complete, the expression of Caspase-3 protein was relatively lower, the expression of GAP-43 protein was relatively higher, the differences have statistically significance (P<0. 05).CONCLUSION: Daizein injection in the vitreous cavity has the capacity of protection and restoration in rat's acute nerve damages.

Objective To investigate the antitumor therapeutic effect of combined therapy of magnetic induction heating by nano-magnetic particles, herpes simplex virus thymidine kinase gene(HSV-tk suicide gene) and internal radiation in mice bearing MCF-7 breast carcinoma. Methods The transfection reagents, plasmids heat shock protein-HSV-tk (pHSP-HSV-tk), ferroso-ferric oxide nano-magnetic fluid flow and 188Re-ganciclovir-bovine serum albumin-nanopaticles (GCV-BSA-NP) were prepared. The heating experiments in vivo were carried out using ferroso-ferric oxide nano-magnetic fluid flow. Sixty mice tumor models bearing MCF-7 breast carcinoma were established and randomly divided into six groups. Group A was the control group, B was gene transfection therapy group, C was hyperthermia group, D was gene transfection therapy combined with radionuclide brachytherapy group, E was gene therapy combined with hyperthermia group, and F was gene therapy, hyperthermia combined with radionuclide brachytherapy group. The tumor growth, tumor mass and histopathological changes were evaluated. The expression of HSV-tk in the groups of B, D, E and F was detected by RT-PCR. Poisson distribution and one-way analysis of variance (ANOVA) were used for statistical analysis by SPSS 10.0 software. Results In the animal heating experiments, the temperature of tumor increased up to 39.6 ℃, 43.2 ℃, and 48.1 ℃ quickly with different injected doses (2, 4 and 6 mg respectively) of nano-magnetic particles and maintained for 40 min. The temperature of tumor tissue reduced to 36.8 ℃, 37.5 ℃ and 37.8 ℃ in 10 min when alternating magnetic field (AMF) stopped. The tumor mass in Groups C ((452.50 ±30.29) mg), D ((240.98 ±35.32)mg), E((231.87 ±27.41) mg) and F ((141.55 ±23.78) mg) were much lower than that in Group A ((719.12±22.65) mg) (F=800.07, P＜0. 01), with the most significant treatment effect in Group F.The tumor mass in Group B((684.05 ±24.02) mg) was higher than that in Group D (t =32. 805, P ＜0. 05). Semi-quantitative RT-PCR analysis showed that the expression of HSV-tk in Groups B and D (0.33 ±0. 13 and 0. 46 ±0.12) was significantly different from that in Groups E and F (0.66 ±0.13 and 0.74 ±0. 11)(F = 21. 573, P ＜ 0.05). Conclusion Combined use of hyperthermia, gene therapy and radionuclide brachytherapy could effectively depress the growth of MCF-7 breast carcinoma, thus possessing treatment potential for this tumor.

Pancreatoblastoma is a rare kind of malignant tumor of pancreas,which is commonly seen among children.A female child aged 5 years was admitted to the Dapiag Hospital with the chief complaint of painless abdominal mass on June 18,2010.The results of B ultrasound showed acoustic shadow of tumor calcification and an absent of normal pancreatic echo.The results of computed tomography(CT)showed that the tumor was located at the body and tail of the pancreas with a low-density and isopycnic shadow of intermixed huge block.The parenchyma of tumor showed unequal enhancement,the periphery showed lobular-like reticular enhancement,the central necrotic area showed no enhancement,and multiple metastatic foci were observed in spleen and liver under enhanced CT scan.The patient underwent resection of the body and tail of the pancreas and the spleen.Chemotherapeutics with vincristine,cyclophosphamide and doxorubicin were adopted postoperatively.After a period of 6-month follow-up,the results of CT showed that the size of tumor was decreased.
