To evaluate the inhibiting effect of Homoharringtonine (HHT) on the corneal haze after excimer laser photorefractive keratectomy (PRK) in rabbits. 18 healthy rabbits which underwent PRK were randomly divided into three groups (A, B and C). The refractive degree of ablation was - 10.0DS in each group. Group A was locally treated with a piece of filter paper soaked with 1 mg/mL HHT for 5 min, and then the entire cornea was repeatedly irrigated with balance solution; Group B was dropped with 0.1 mg/mL HHT after PRK for 3 months; Group C was the control group. Corneal haze, histopathology, response, ect. were investigated. The corneal haze was significantly less in group A, while the difference between group B and group C was insignificant. Keratocytes and fibrocytes in corneal stroma were more active up to 3 months in group B and group C. Intraoperative use of topical HHT can reduce corneal haze after PRK in rabbits.

Objective To establish a spontaneous abortion rat model for a syndrome in traditional chinese medicine, kidney deficiency, and observe the changes of physiological indicators and related cytokine expression in the model. Methods 40 female and 20 male rats were used in this study. The female and male rats were mated (mating ratio 2:1). The day of vaginal smear with a large number of sperm was considered as the first day of pregnancy. The rats were randomly divided into control group and model group. The model group received 450 mg/kg hydroxyurea every day. Mifepristone was given on the eighth day in a dose of 3.75 mg/kg. The diet amount, the diameter index of kidney, ovary and embryos were analyzed. The mRNA expression of Th1/Th2 cytokine was detected by RT-PCR, and the expression of co-stimulating factors CD80, CD86, CD28, CTLA-4 were determined by flow cytometry.Results Comparing the model group with control group on the eighth day, there were significant differences between the model and control groups in quantity of food and water intake, and weight increase (P<0.05), and also in the embryonic diameter index, average of abortion rate, Th1/Th2 type cytokines, co-stimulating factor CD80, CD86, CD28, and CTLA-4 (P<0.05). Conclusion A rat model of spontaneous abortion due to kidney deficiency can be successfully established with hydroxyurea and mifepristone. The high expression of Th1 (TNF-α, IFN-γ) may cause abortion and be harmful to pregnancy. Th2 type (IL-4, IL-10) may facilitate pregnancy. The expression co-stimulating factor CD80, CD86, CD28, CTLA-4 may be relevant to the spontaneous abortion.

By using the methods of experience summary and case report, professor's clinical experience of acupuncture for migraine was summarized.Professorproposed the different acupuncture plans should be established according to the active stage and remission stage of migraine; in the active stage acupuncture should be applied at gallbladder meridian with penetration needling technique to reinforce the stimulation intensity; in the remission stage the aim was to regulateand back-points should be emphasized.In addition, attention should be paid on acupuncture technique and preventive treatment.For menstruation-type and psychological disorder-type migraine, different acupuncture plans should be adopted and regulating meridian and spirit was essential in the treatment.

Neurogenic orthostatic hypotension （nOH） is a common neurodegenerative disease， and is usually differentiated as kidney-yang depletion syndrome in traditional Chinese medicine （TCM）. Fire needling on governor vessel （督脉） acupoints as well as Shenshu （BL 23） and Zhishi （BL 52） can dredge the qi and blood of governor vessel， so as to warm yang and unblock the channels， supplement essence and boost marrow. A case of elderly nOH treated by fire needling mainly at governor vessel points， Shenshu （BL 23） and Zhishi （BL 52） was reported. After nearly two months of treatment， the patient's orthostatic blood pressure difference and yang deficiency-related symptoms were significantly improved， and the results of blood pressure monitoring， TCM syndrome scale evaluation and Shenshu （BL 23） area infrared imager detection all showed definite clinical effect.

OBJECTIVE: To observe the effect of acupoint injection of bone mesenchymal stem cells (BMSCs) combined with Chinese herbs of benefiting for activating blood circulation for capillary density and arterioles density in skeletal muscle in ischemic hind limb of diabetes mellitus (DM) rats. METHODS: A total of 80 rats were randomized into a normal sham operation group (10 rats) and a model group (70 rats). Disposable intraperitoneal injection of streptozotocin (STZ, 50.0 mg/kg) was used to establish DM model, and the rats in the model group were randomized into 7 subgroups, 10 rats in each one. The subgroups were the DM sham operation group, DM ischemic group, Chinese herb group (intragastric herbs of benefiting for activating blood circulation), local injection group (BMSCs local injection), local injection + Chinese herb group (BMSCs local injection combined with intragastric herbs of benefiting for activating blood circulation), acupoint injection group (BMSCs acupoint injection), acupoint injection + Chinese herb group (BMSCs acupoint injection combined with intragastric herbs of benefiting for activating blood circulation). The local injection was phosphate buffer (PBS) injection at the equidistant 5 points along the line between the ischemic tissue and the normal tissue a time. The acupoints were "Sanyinjiao" (SP 6), "Zhaohai" (KI 6), "Huantiao" (GB 30), "Housanli" (ST 36) and "Yanglingquan" (GB 34). 100 μL BMSCs with 1×10/mL was totally injected at the above acupoints for one rat, 20 μL an acupoint. 1.5 kg/L Chinese herbs were applied by intragastric administration, including 120 g Radix Astragali, 120 g Codonopsis, 48 g Radix Glycyrrhiza, 120 g Angelica sinensis, 120 g Blood Rattan, 48 g Achyranthes bidentata. Intragastric distilled water was used in the other non-Chinese herb groups. The expressions of α-smooth muscle actin (α-actin), latelet endothelial cell adhesion molecule (CD31) and von willebrand factor (vWF) in the skeletal muscle were detected with immunohistochemical SP two-step method. RESULTS: Twenty-one days after intervention, the expressions of α-actin and CD31 on the operation hind limb were higher than those on the healthy hind limb in all the groups, except the Chinese herb group (<0.05<0.01). The vWF expressions on the operation side were lower than those on the healthy side in the Chinese herb group, the local injection group, the local injection + Chinese herb group and the acupoint injection + Chinese herb group (<0.05, <0.01). The α-actin expression on the operation side in the acupoint injection + Chinese herb group was higher than those in the normal sham operation group, DM sham operation group, the DM ischemic group and the local injection group (<0.05, <0.01). The CD31 expressions in the acupoint injection group, the acupoint injection + Chinese herb group, local injection + Chinese herb group were higher than those in the normal sham operation group, DM sham operation group and DM ischemic group (<0.05, <0.01). The CD31 expression in the acupoint injection + Chinese herb group was higher than those in the Chinese herb group and the local injection group (both <0.05). The vWF expressions in the local injection + Chinese herb group, the acupoint injection group and the acupoint injection + Chinese herb group lower than those in the DM sham operation group and the DM ischemic group (<0.05, <0.01). CONCLUSION schemia increases the expressions of the vascular density related factors of α-actin and CD31. It is more obvious for the increasing expressions of α-actin and CD31, and decreasing expression of vWF with the interventions of simple BMSCs injection and simple Chinese herbs of benefiting for activating blood circulation, especially with the combination of the above tow methods. It is indicated that acupoint injection of BMSCs combined with Chinese herbs of benefiting for activating blood circulation can improve the angiogenesis of ischemic tissue.
