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.

Objective To study the correlations between the TCM syndromes of gastrointestinal dyskinesis and the disorders of gastrointestinal hormone,electrogastrogram(EGG) and blood gas in patients with chronic obstructive pulmonary diseases(COPD) and cor pulmonale.Methods The 120 cases of COPD and cor pulmonale were diagnosed with TCM syndrome differentiation,and plasma motilin(MOT),vasoactive intestinal peptide(VIP),Gastrin(GAS),EGG and blood gas were anglyzed and compared with 26 healthy subjects.Results With the aggravation of COPD and cor pulmonale,the dyskinesis of stomach and intestine was getting worse,developed from Shi-excess to Xu-deficiency.In deficiency syndrome,basic electrorhythm decreased most obviously.In phlegm-damp in lung syndrome,MOT and GAS decreased most obviously.In lung-kidney deficiency syndrome and lung-spleen-kidney deficiency syndrome,VIP increased most obviously.In lung-spleen-kidney deficiency syndrome,anoxia and carbon dioxide retention were most serious but GAS increased.Conclusion All patients of COPD and cor pulmonale have dyskinesis of stomach-intestine to a certain degree,abnormal EGG and disordered gastrointestinal hormones.Severity of ventilatory disturbance,quantity of injured organs,and condition of anoxia due to gastrointestinal blood stasis are all correlated with the development of COPD and cor pulmonale.

[Objective]To evaluate the accuracy of computer-assisted cervical pedicle screw installation and discuss the reasons of screw malposition.[Method]Totally 144 cervical pedicle screws were installed by computer-assisted navigation in 25 patients with lower cervical spinal disease.All the patients were examined by X-rays and CT after operation.Screw position and direction were measured on the sagittal and transsection image of intraoperative navigation and post-operative CT.The result was analyzed statistically.[Result]Two screws perforated the upper pedicle wall,3 deviated from the lateral pedicle wal1.There was no statistical difference in screw position or direction between navigation and CT image.Navigational images were based on the principle of rigid tissue.[Conclusion]Computer-assisted navigation can improve the accuracy of cervical pedicle screw installation.Screw malposition is responsible for the excursion phenomenon.

OBJECTIVE:To observe therapeutic efficacy and safety of Zhenqi fuzheng granules in the adjunctive treatment of cervical cancer. METHODS:86 patients with cervical cancer were randomly divided into control group(43 cases)and observation group (43 cases). Control group was given intravenous dripping of Diphenhydramine hydrochloride injection 20 mg,Granisetron hydrochloride and glucose injection 5 mg,Cimetidine injection 20 mg at 0.5 h before chemotherapy. After 0.5 h of intravenous drip-ping,the patients received chemotherapy:Docetaxel injection 40 mg/m2,d1,d8,intravenous dripping;Cisplatin for injection 25 mg/m2,d1-3,intravenous dripping;21 d as a cycle,a total of 4-6 cycles. On the basis of control group,observation group was addi-tionally given Zhenqi fuzheng granules 5 g,twice 2 day. Clinical efficacies of 2 groups were observed as well as T cell subsets in-dexes [CD3+,CD4+,CD8+,natural killer cell(NK)],KPS scores,termination,terminal time,the times of chemotherapy and the oc-currence of toxic reaction before and after treatment. RESULTS:The total remission rate of observation group was significantly higher than that of control group;the proportion of termination of chemotherapy in observation group was significantly lower than control group;terminal time of chemotherapy was significantly shorter than control group;the times of chemotherapy was signifi-cantly more than control group;the incidence of gastrointestinal reaction,anemia,thrombocytopenia and leukopenia were signifi-cantly lower than control group,with statistical significance(P<0.05). There was no statistical significance in liver function dam-age,renal function injury and stomatitis between 2 groups (P>0.05). Before treatment,there was no statistical significance in T cell subsets indexes and KPS scores between 2 groups(P>0.05). After treatment,CD3+,CD4+ and NK cells in observation group were significantly higher than before treatment and control group,while CD8+ was significantly lower than before treatment and control group;KPS scores of 2 groups were significantly higher than before,and the observation group was significantly higher than the control group,with statistical significance(P<0.05). There was no statistical significance in T cell subsets indexes of con-trol group before and after treatment(P>0.05). CONCLUSIONS:On the basis of routine treatment,Zhenqi fuzheng granules can improve therapeutic efficacy,immune function and the quality of life,moreover,reduce toxic reaction in patients with cervical can-cer.

Objective To study the expression of aquaporins(AQPs) in the inner ear of normal guinea pig and guinea pigs with endolymphatic hydrops, and to investigate the mechanism and significance. Methods The guinea pigs were divided into two groups randomly: model group and control group. The guinea pigs in model group were given desmopressing 4 ?g?kg-1?d-1 introperitoneally for 1 week, while the guinea pigs in control group were given saline. After one week, the expression of AQPs in the inner ears of all guinea pigs was evaluated.Results Expression of AQP0, 1, 2, 3, 5, 7 and 8 were found in the ears of normal guinea pigs. Weak expression of AQP0 was found in stria vascularis and spiral ganglion. The distribution of AQP1 consisted of cellular lining the bony labyrinth, fibrocytes lining in the endolymphatic duct and sac, cells under the basilar membrane, fibrocytes of the spiral ligament and the spiral limbus, Corti's organ, inner and outer spiral sulcus, stria vascularis, saccular and utricular wall, and spiral ganglion. AQP2 were found in stria vascularis, Corti's organ, spiral ganglion and endolymphatic sac. AQP3, 7 and 8 were distributed in a similar manner as the surrounding membranous labyrinth, including Corti's organ, inner and outer spiral sulcus, stria vascularis, fibrocytes of the spiral ligament and the spiral limbus, saccular and utricular wall, endolymphatic sac and spiral ganglion. AQP5 was found at Corti's organ, inner and outer spiral sulcus, spiral ganglion and fibrocytes in spiral ligment. The AQP2 in stria vascularis and endolymphatic sac was stronger in the inner ears with ELH than that in normal ears.Conclusion There are various AQPs in inner ears of normal guinea pigs, and their distributions are overlapping and without obvious regional specificity. Desmopressing induces the expression of AQP2 in the inner ears of guinea pigs. The results indicate that ELH may correlate to upregulation of AQP2, but the mechanism remains unclear.
