OBJECTIVE:To observe clinical efficacy and ADR of blue and red light phototherapy combined with TCM exter-nal treatment in the treatment of ecthyma. METHODS:64 ecthyma patients were randomly divided into experimental group and control group by number with 32 cases in each group. Both groups were provided with intravenous drip of Erigeron injection and Shenxiong glucose injection to improve limb microcirculation. The experimental group was also provided with blue and red light phototherapy (blue light 20 min+ red light 20 min) combined with TCM external treatment once a day;while control group was provided with only TCM external treatment once a day. After 1 month treatment,clinical efficacy and healing time of 2 groups were observed and compared,and ADR monitoring was conducted. RESULTS:The cure rate of experimental group was 78.13%, and the total effective rate was 96.88%,which were higher than those of control group(40.63% and 81.25%),there was statisti-cally significant difference (P<0.05). The average healing time of experimental group was (18.75 ± 5.97) d,and that of control group was(27.12 ± 6.67)d;there was statistically significant difference between 2 groups (P<0.05). No ADR was found in 2 groups during treatment. CONCLUSIONS:Blue and red light phototherapy combined with TCM external treatment in the treatment of ecthyma has the remarkable curative effect and good safety,and shorten the healing time.

We present the binding ability of a new peptide (CMPQVMPMC-) with dental enamel after being evaluated in the present study. Under a standard procedure, the recovery of M13 filamentous phage was greatly enhanced by displaying the peptide in phage coat protein p III. Then the cyclic peptide was synthesized using a solid method. The effect of the cyclic peptide in vitro biomineralization was tested in a single-diffusion microtiter plate gel system. Absorbance at 405 nm of each sample was recorded for 24 h at every 6 h intervals. The relatively increased values of each sample were expressed as percentages relative to the blank group (100%). The cyclic peptide resulted in a concentration-dependent delayed nucleation. In addition, the overall values of peptide groups at the end of 24 h were lower than those in the control group but much higher than those in the BSA control group.

Objective To study the role of gasless laparoscopic techniques in the treatment of abdominal trauma. Methods A retrospective analysis was made on clinical data of 52 cases of abdominal trauma considered unfit for pneumoperitoneum treated by gasless laparoscopic surgery. Results Prompt diagnosis and treatment were achieved in 43 cases. A conversion to laparoscopic exploration under pneumoperitoneum was required in 5 cases. The remaining 4 cases of severe injuries of the spleen and the bowel were cured by a conversion to open surgery after the determination of the incision site under gasless laparoscope. There were no fatal cases in the study. Conclusions Use of gasless laparoscopic techniques for the diagnosis, treatment and determination of incision site in patients with abdominal trauma considered unfit for pneumoperitoneum is feasible. It is a necessarily additional alternative to traditional laparoscopic surgery.

Objective To learn the incidence of the inherited metabolic diseases in Beijing. Methods Urine samples were analyzed by gas chromatography-mass spectrometry(GC-MS)for inherited metabolic diseases in high risky infants in Beijing . Results Urine samples from 411 high risky infants were analyzed by gas chromatography-mass spectrometry. 269 cases (65.5%) were detected to have metabolic abnormalities, including 19 cases (4.6%) diagnosed of inherited metabolic diseases in which there were 15 cases of methylmalonic academia and 1 case each of propionic academia, hyperphenylalaninemia, urea cycle abnormality and pyroglutamic aciduria. There were 22 suspected cases (5.4%) of inherited metabolic diseases including 13 cases of lactic acidosis, 5 cases of primary glycerol aciduria, 4 cases of fatty acid metabolic disorders including 1 case each of Citrin defects, tyrosinemia, galactosemia 3-methylcrotonoyl coenzyme A carboxylase deifciency and maple syrup urine disease. There were also 228 cases (55.5%) of metabolic abnormalities, such as increasing urine levels of lactic acid, sucrose,lactose, galactose, N-acetyl tyrosine, succinic acid, dicarboxylic acid and abnormal serine/threonine ratio. Conclusions Methylmalonic academia might be the most common inherited metabolic diseases in high risky infants in Beijing. For infants with clinical manifestations but unclear etiology, GC-MS should be performed. MS-MS and gene analysis could be combined if necessary.

Objective To analyze the risk factors of root caries.Methods With randomly stratified cluster sampling method,we selected 600 elderly in Tangshan city and performed oral examination.Data was analyzed by Logistic regression analysis.Results Gingival recession,age,oral calculus index,false tooth restoration were the risk factors of root caries.The vertical brushing tooth method and using fluoride toothpaste were the protective factors.Conclusion Gingival recession,age,oral calculus index(CI-S),false tooth restoration were the major risk factors of root caries.
