· AIM: To evaluate the safety of eye anterior tissue when plasmin (Pm) and hyaluronidase (HS) are injected into pigs'vitreouses to induce posterior vitreous detachment(PVD).· METHODS: 15 pigs without ocular diseases were randomly assigned to groups A,B,C (5 in each group). For each pig, one eye was experimental, the other eye was control. The experimental eye received intravitreal injection with enzyme:group A: 50U(0.1mL) HS; group B: 0.5U(0.1mL) Pm; group C: 0.5U(0.05mL) Pm combined with 50U(0.05mL) HS; while the control eye received intravitreal injection with equivalent dose of balanced salt solution (BSS). Postoperative reactions in the eyes were carefully observed by clinical examinations such as slit-lamp microscopy and direct and indirect ophthalmoscopy and measurement of intraocular pressure (IOP). Eyeballs were extirpated 7 days after the operation and histological examination was carried out. The corneas and irises were observed under light microscope (LM). The epithelia of ciliary bodies and lens were studied with transmission electron microscope (TEM).· RESULTS: In all experimental eyes and control eyes of group A, B and C, histological examination showed: under LM ,the corneas and irises of experimental eyes had no histological abnormality in structure; Under TEM, epithelial cells of ciliary bodies and the lens were tightly arrayed with clear cellular boundaries, clear intracellular structure, intact cell membranes, and intact nuclei; There was no significant difference in the clinical examinations and in the change of IOP between preoperation and postoperation, between the experimental group and the control group.· CONCLUSION: With 0.5U Pm and HS 50U injected into pigs' vitreouses to induce PVD, alone or combined with two enzymes, evaluation revealed no evidence of toxicity on the eye anterior tissue. The dosage was proved to be safe for eye anterior tissue.

Concealed penis is usually found in children, which affects the patients both physiologically and psychologically. Some of the patients are wrongly treated by circumcision, which may bring about serious consequences to the sexual life of the patients in their adulthood. In the recent years, this disease has been receiving more and more attention from both doctors and parents. However, controversies remain as to its classification, pathogenesis, pathology, and treatment. This paper focuses on the understanding and advances in the studies of concealed penis.

OBJECTIVETo evaluate the clinical effects of the massage method of micro-regulating with vertical cross pressing lying on one side in treating cervicogenic headache (CEH).

METHODSTotal 136 patients with CEH were collected in the study from August 2012 to April 2014. They were divided randomly into two groups according to random digits table. Sixty-nine patients accepted the treatment of micro-regulating with vertical cross pressing lying on one side (pressing micro-regulating group), including 29 males and 40 females with an average age of (50.55 ± 11.38) years old; 67 patients received the treatment of traditional massage (traditional massage group), including 28 males and 39 females with an average age of (51.20 ± 11.90) years old. Clinical effect was observed according to the standard of curative effect of State Administration of Traditional Chinese Medicine; the function of cervical vertebra and all body status were evaluated according to NDI score. VAS score, frequency and time of headache were recorded and compared before and after treatment.

RESULTSNo adverse reactions were found after treatment, all patients were followed up from 1 to 6 months with an average of 3.1 months. In pressing micro-regulating group, 25 cases got fully recover, 26 excellence, 14 effectiveness and 4 inefficiency; and in traditional massage group, the results were 12,21,22, 12;clinical effect of pressing micro-regulating group was better than that of traditional massage group (P<0.01). NDI score in pressing micro-regulating group decreased from preoperative 13.48 ± 4.83 to postoperative 6.23 ± 3.76; in traditional massage group also decreased from preoperative 13.82 ± 5.78 to postoperative 8.25 ± 4.75; the improvement of the pressing micro-regulating group was obviously better than that of traditional massage group (P < 0.01). VAS score in pressing micro-regulating group decreased from preoperative 4.75 ± 0.97 to postoperative 1.88 ± 1.78; and in traditional massage group decreased from pre-operative 4.78 ± 0.98 to postoperative 2.84 ± 1.94; pressing micro-regulating group was more notable than that of traditional massage group (P < 0.01). The frequency per week,the pain time in pressing micro-regulating group decreased from preoperative (5.38 ± 1.96) times and (6.87 ± 3.67) hours to postoperative (1.71 ± 2.04) times and (0.97 ± 1.74) hours,respectively,in traditional massage group the above parameters decreased from preoperative (5.22 ± 1.81) times and (6.90 ± 3.79) hours to postoperative (2.81 ± 2.42) times and (1.83 ± 2.21) hours;pressing micr-regulating group was more notable than that of traditional massage group (P < 0.01 or P < 0.05).

CONCLUSIONUsing the tuina method of micro-regulating with vertical cross pressing lying on one side to treat CEH can improve function of cervical vertebra and all body status, lessen the intensity, frequency, duration time of pain, and had advantage of higher security, simple operation, and evident effect.

This paper analyzed the necessity of due diligence in hospital mergers and acquisitions from the perspective of two trading parties,and summarized such roadblocks in hospital due diligence,as lack of awareness,information asymmetry and lack of co-ordination of the investigated.Going through the five main aspects of due diligence in hospital mergers and acquisitions,including business due diligence,financial due diligence,human resource due diligence,legal due diligence and hospital environmental and occupational safety due diligence,the authors put forward pertinent suggestions and countermeasures on efficient due diligence work.

Objective: To evaluate the effect of Jinqijiangtang Tablet prepared by new technology on blood glucose and lipids in rats with type 2 diabetes. Methods: Type 2 diabetic rat model was established by high fat diet combined with STZ injection. Metformin was used for a positive drug in the present study. Fasting blood glucose, glycosylated serum protein, serum insulin, and insulin resistance index were determined to evaluate the hypoglycemic effect of Jinqijiangtang Tablet prepared by new technology. And serum triglyceride, cholesterol, high density and low density lipoprotein were observed to evaluate the lipid-lowering effect of Jinqijiangtang Tablet prepared by new technology. Results: Jinqijiangtang Tablet prepared by new technology and metformin both could reduce the fasting blood glucose and glycosylated serum protein, and improve glucose tolerance and insulin resistance. Jinqijiangtang Tablet could reduce the levels of cholesterol and HDL.Conclusion: Jinqijiangtang Tablet prepared by new technology can effectively improve insulin resistance, and it has a lipid-lowering effect.

The formation of malignant ascites is concerned with non-obstructive factors including immunity regulator(IL-2,TNF,IFN-?)and factors of inducing blood vessel penetrability(VEGF,MMP) besides obstructive factors. Intraperitoneal chemotherapy makes drug directly act on peritoneum and arrives at the aim of controlling and treating malignant ascites.
