AIM:To evaluate the clinical effect of traditional Chinese medicine plus laser photocoagulation on eyes which have peripheral retinal hole with shallow detachment.
METHODS: The 227 cases ( 246 eyes ) of retinal hole with shallow detachment were randomly divided into an integrated Chinese and western medicine group and a western medicine group. The former underwent laser photocoagulation combined with oral Chinese medicine;while the latter was treated with laser photocoagulation alone. Analyses of the effect were performed two months after treatment.
RESULTS:The total cure rate of integrated Chinese and western medicine group was 87. 7%, while that of western medicine group was 71. 6%, significant difference was considered between the two groups (P<0. 01).
CONCLUSION: Chinese medicine combined with laser photocoagulation plays an exact role in eyes which have peripheral retinal hole with shallow detachment, especially when the detached range is greater than 1PD, and it is significantly better than western laser therapy.

To study the chemical constituents from the bark of Myrica rubra, fourteen compounds were isolated from the methanolic extract using various chromatographic techniques, including silica gel, Sephadex LH-20 and preparative HPLC. Their structures were identified on the basis of chemical properties and spectroscopic data, as 3, 5-dimethoxy-4-hydroxymyricanol (1), myricanol (2), myricanone (3), myricanol 11-sulfate (4), myricitrin (5), quercetin (6), quercetin-3-rhamnoside (7), tamarixol (8), uvaol (9), ursolic acid (10), taraxerol (11), myricadiol (12), β-sitosterol (13) and β-daucosterol (14).

OBJECTIVETo investigate the effects of hysteroscopic treatment of women with previous cesarean scar defect (PCSD).

METHODSFrom May 2006 to October 2008, 12 patients with PCSD were diagnosed and treated hysteroscopically in our hospital, all of them were successful followed-up for one year postoperatively, and their clinical data were analyzed.

RESULTSAll 12 hysteroscopic procedures were completed successfully, and there were no surgical complications. Nine patients with longer periods and 1 patient with intermenstrual spotting preoperatively remained asymptomatic after hysteroscopic surgery, and 1 patient with longer periods and infertility experienced normal periods, while remained infertility, and the remaining 1 patient complaining postcoital bleeding preoperatively had recurrence of the bleeding.

CONCLUSIONHysteroscopic surgery of women with PCSD was minimally invasive and effective.

Bispecific antibodies have been exploited as both cancer immunodiagnostics and cancer therapeutics, which have shown promises in clinical trials in cancer imaging and therapy. To improve the anti-tumor effect, an scDb (bispecific single-chain diabody) was constructed from the variable domain genes of two scFvs (single-chain variable fragment antibodies) directed against human EGFR (epidermal growth factor receptor) and VEGFR2 (vascular endothelial growth factor receptor 2) extracellular domains. The anti-EGFR/ anti-KDR scDb was constructed into pHEN2 plasmid and expressed in Escherichia coli HB2151 host. After purification by one-step affinity chromatography of IMAC, scDb protein was characterized by Western blotting. The yield of scDb protein was 570 microg per liter medium. scDb bound to EGFR as efficiently as the parental antibody scFv-E10, while a little bit weaker than the parental antibody scFv-AK404R when bound to KDR. In conclusion, the scDb protein could bind both EGFR and KDR specifically and could be applied for further anti-tumor research.

The deubiquitinating enzyme ubiquitin specific peptidase 15 (USP15) is regarded as a regulator of TGFβ signaling pathway. This process depends on Smad7, the inhibitory factor of the TGFβ signal, and type I TGFβ receptor (TβR-I), one of the receptors of TGFβ. The expression level of USP15 seems to play vital roles in the pathogenesis of many neoplasms, but so far there has been no report about USP15 in psoriasis. In this study, immunohistochemical staining of USP15, TβR-I and Smad7 was performed in 30 paraffin-embedded psoriasis specimens and 10 normal specimens to investigate the expression of USP15, TβR-I and Smad7 in psoriasis and to explore the relevance among them. And USP15 small interfering RNA (USP15 siRNA) was used to transfect Hacat cells to detect the mRNA expression of TβR-I and Smad7. Of 30 cases of psoriasis in active stage, 28, 24 and 26 cases were positive for USP15, TβR-I and Smad7 staining, respectively. The positive rates of USP15 and Smad7 were significantly higher in psoriasis specimens than in normal skin specimens (44.1%±26.0% vs. 6.1%±6.6%, 47.2%±27.1% vs. 6.6%±7.1%), and positive rate of TβR-I (20.3%±22.2%) in psoriasis was lower than that in normal skin specimens (46.7%±18.2%). There was a significant positive correlation between USP15 and Smad7 expression, and significant negative correlations between USP15 and TβR-expression, an I d between TβR- and Smad7 expression I in psoriasis. After transfection of USP15 siRNA in Hacat cells, the expression of TβR-mRNA was up I -regulated and that of Smad7 was down-regulated. It is concluded that USP15 may play a role in the pathogenesis of psoriasis through regulating the TβR-I/Smad7 pathway and there may be other cell signaling pathways interacting with USP15 to take part in the development of psoriasis.

Objective To observe the effect of hypoxia reoxygenation on activity of superoxide dismutase(SOD)and MDA content as well as[Ca~(2+)],concentration and mitochondria membrane poten- tial of intestinal epithelial cell-6(IEC-6)in IEC culture medium and explore the protective effect and mechanism of serum containing Ziqi-liquid(a preparation of Chinese herbal medicine)on hypoxia reoxy- genation damaged IEC-6.Methods Hypoxia reoxygenation damage model of IEC-6 was made.SOD activity and MPA content in IEC-6 culture medium were determined by ultraviolet spectrometry after hy- poxia reoxygenation and treatment with Ziqi-liquid.Meanwhile,MMP changes and[Ca~(2+)]concentration were detected by laser scanning confocal microscopy.Results After hypoxia reoxygenation,SOD and MMP were significantly decreased,but MDA content and[ Ca~(2+)] concentration significantly increased (P＜0.01),and significantly facilitated by serum containing Ziqi-liquid.Conclusion Hypoxia reoxy- genation can damage IEC-6,but the serum containing Ziqi-liquid has significant protective effect on it.

Objective: To observe the clinical efficacy of acupuncture plus bloodletting therapy in treating insomnia in people with blood stasis constitution. Methods: Seventy-two patients were randomized into a treatment group and a control group by using the random number table, 36 cases each. The treatment group received acupuncture plus bloodletting therapy, while the control group was intervened by oral administration of estazolam. One-week treatment was taken as a course, for 3 successive courses in total. A follow-up study was conducted 3 months later. The Pittsburgh sleep quality index (PSQI) was evaluated before and after the intervention, as well as in the follow-up. The clinical efficacies were also compared. Results: The total effective rate was 88.9% in the treatment group versus 83.3% in the control group, and the between-group difference was statistically significant (P<0.05). After the intervention, the PSQI scores dropped significantly in both groups (both P<0.05); the between-group difference in PSQI score was statistically significant (P<0.05). The follow-up study showed that the between-group difference in the global score of PSQI was statistically significant (P<0.05). Conclusion: Acupuncture plus bloodletting therapy can produce a more significant efficacy than oral administration of estazolam in treating insomnia in people with blood stasis constitution.
