Blue light has been widely used for the treatment of neonatal hyperbilirubinemia since the 1950s. Neonatal phototherapy can decrease plasma unconjugated bilirubin level, thus preventing bilirubin encephalopathy, and greatly reduces the exchange transfusion rate. Generally, it is accepted that the side effects of neonatal phototherapy are not serious and seem to be well controlled, however recent research has provided new evidence. The short-term side effects of phototherapy include interference with maternal-infant interaction, imbalance of thermal environment and water loss, electrolyte disturbance, bronze baby syndrome and circadian rhythm disorder. In addition, phototherapy may be associated with some long-term side effects such as melanocytic nevi and skin cancer, allergic diseases, patent ductus arteriosus and retinal damage. Therefore, it is necessary to develop evidence-based guidelines, new light devices and alternative agents, as well as individualized treatments, to minimize the side effects of phototherapy.

Objective To retrospectively analyze 45 cases of oral and maxillofacial malignant tumors and to assess the efficacy and feasibility of oral and maxillofacial malignant tumors implanted with 125I radioactive seeds under guidance of ultrasound.Methods A total of 47 focuses in these 45 patients were determined with the size of these tumors by imaging study,the section was planed by ultrasound,the number and distribution of radioactive seeds were determined with the help of the particle treatment planning system,and were percutaneously implanted particles under guidance of ultrasound.The number and the distribution of particles were assessed by CT.Efficacy endpoints were reexamined and evaluated regularly by ultrasonic and CT according to the standards of WHO.Results The total percentage of efficacy was 70.2% (including complete remission,partial remission).The treatment effect of metastatic carcinoma of lymph node is superior to the parotid tumor.There was no serious complication during the period of implanting and 2 patients with oral ulcers were found after operation.Conclusion The oral and maxillofacial malignant tumor treated implanted with 125I radioactive seeds under guidance of ultrasound is very effective and safe,which is deserved to popularize.The ultrasound is the first choice as a guided method for oral and maxillofacial malignant tumors.

Objective To analyze the antimicrobial susceptibility of Mycoplasma isolates for rational antimicrobial therapy. Methods BioM?rieux IST kit was used for identification and susceptibility testing of Mycoplasma strains.Results Mycoplasma was positive in 49.5% of the specimens tested.Of the Mycoplasma detected,Ureaplasma urealyticum(Uu)alone accounted for 74.7%,Mycoplasma huminis(Mh)alone accounted for 18.1%,and Uu+Mh was identified in 7.2% of the patients.The results of antimicrobial susceptibility testing showed that the Mycoplasma isolates were most susceptible to doxycycline (98.1%).Ciprofloxacin was the least active (17.3%).Conclusions Doxyeycline,josamycin,and clarithromycin can be used in the treatment of urinary tract infections caused by Mycoplasma.

OBJECTIVETo investigate the effect of Busheng Huoxue Capsule (BHC) on the quality of life (QOL) in senile male osteoporosis (OP) patients, and to explore its mechanisms.

METHODSTotally 200 senile primary OP patients were randomly assigned to two groups according to random digit table method, 100 in each group. Patients in the treatment group took BHC plus caltrate-D (600 mg CaCO3), while those in the control group took alendronate (70 mg per week) plus caltrate-D. The therapeutic course was 12 months for all. Chinese medical symptom score and quality of life (QUALEFFO-41) score, bone mineral density (BMD) of lumbar vertebra (L2 -L4) and left femoral neck were compared between the two groups before and after treatment. Serum free testosterone (FT) and estradiol (E2) were also measured.

RESULTSChinese medical symptom scores and QUALEFFO-41 scores, serum FT and E2 levels increased in the two groups after treatment (P < 0.05, P < 0.01). The therapeutic effect was superior in the treatment group (P < 0.05, P < 0.01). After treatment the BMD of lumbar vertebra (L2 -L4) and the left femoral neck were somewhat improved (P < 0.05), but with no statistical difference between the two groups (P > 0.05).

CONCLUSIONBHC could effectively improve the QOL of senile male OP patients, which might be correlated with elevating the BMD levels and regulating the levels of sex hormones.

Objective To observe the changes of rat microglial inflammation and migration after exposure to sodium metavanadate(NaVO3·2H2O), and to analyze the possible mechanisms of vanadium neurotoxicity. Methods Primary cultured rat microglial cells were incubated with NaVO3·2H2 O. Morphological changes and the Iba1 expression of microglia were tested by immunofluorescence assay. iNOS, Cox-2, ERK and p-ERK protein expressions were determined by western blotting. The levels of TNF-α and IL-1β in the culture medium were tested by enzyme-linked immunosorbent assay. The migration of microglia was tested by immunofluorescence staining using wound-healing assay. Results Microglia changed from resting state with ramous shape to round shape in activated state after NaVO3·2H2 O exposure, and the expression of Iba1 increased obviously. The protein expressions of iNOS and COX-2 increased significantly compared with the control. The levels of TNF-αand IL-1βwere also increased significantly. NaVO3·2H2 O promotes the migration of microglia through ERK pathway. Conclusions Exposure to NaVO3·2H2 O promotes primary cultured rat microglial inflammation and migration. These results suggest that the inflammatory reaction of microglia may be one of the possible mechanisms of neurotoxicity caused by vanadium exposure.

OBJECTIVETo investigate the relationship between cardiac Cerebrovascular disease and serum uric acid(SUA) in the coastal inhabitant, and try to provide base for prevention of the local metabolic disease and cardiac Cerebrovascular disease.

METHODWe got 3111 local people who had participated in the annual physical examination in the perch hospital for the research on the level of SUA and the relative risk factor. According to SUA level we divided the cases into two groups. One is hyperuricemia group and the other is control group.

RESULTS(1)The average SUA level was (380.2-/+62.58) micromol/L in the males, while (290.82-/+60.32) micromlo/L in the female. The sick rate of hyperuricaemia rate, was 21.8% for male, and the 17.6% of female. This disease affected more men than women. It has significant difference (P<0.01); (2)The SUA level of the showed a positive correlation with the indexes of the total cholesterol, the triglyceride, the blood pressure and the body weight index. The SUA level in overweight/obesity people was obviously higher than that of the normal weight people.

CONCLUSIONS(1)The sick rate of hyperuricaemia is high in Zhongshan coastal area, which due to many related factors. As far as, few people know it, so we should adopt the synthesis measure to prevent and control it to reduce the sick rate; (2)the rise of The SUA level possibly becomes one of the independent dangerous and predictive factor for the heart cerebral von disease.
