Objective To observe angiogenic effect of platelet-released growth factors (PRGF) from platelet-rich plasma (PRP) on mierovessel formation at early stage after anterior crueiate ligament (ACL) reconstruction by freeze-dried Achilles tendon. Methods The study involved 14 rabbits, of which 12 rabbits were used as experiment group and the other 2 as control group. In the experiment group, after two sides of rabbit ACL were removed, freeze-dried Achilles tendon treated by PRGF was transplanted into random one side of the knee to substitute the original ACL (PRGF group), while the other side was transplanted with freeze-dried Achilles tendon treated only by normal saline (NS group). Only one side of the knee was removed in the control group. The grafts were observed by HE and immuno- histeehemical staining 2, 4 and 6 weeks after operation. Microvessel density (MVD) was measured by Weidner method. Results Compared with NS group, MVD in PRGF group was significant higher at 2,4 and 6 weeks after operation (P<0.05). MVD of NS group at 2,4 and 6 weeks after operation was 2.52±0.45, 3.41±0.44 and 2.57±0.51 respectively, but that of PRGF group at 2,4 and 6 weeks af- ter operation was 3.56±0.81,4.91±0.46 and 3.01±0.75 respectively (P<0.05). The time of neo- vascular formation and the depth of vascular penetration into the grafts of the PRGF group were superior to those of NS group. Conclusion PRGF can significantly promote microvessel formation at early stage after ACL reconstruction with freeze-dried Achilles tendon.

Microbial selective side-chain degradation of phytosterol,which can obtain the steroid medicine intermediate compounds-androst-4-ene-3,17-dione (4-AD) and androsta-1,4-diene-3,17-dione (ADD),has an important meaning to pharmacy. There is no systematic literature concerned in existence. Its mechnism,approaches,influencing factors and so on over these years were fully reviewed in the paper. The trend of development in the area is expanded.

Objective:To establish an HPLC method for the determination of related substances in enalapril maleate dispersible tablets.Methods:AKromasil100-SC8(250mm×4.6mm,5μm)columnwasused. ThemobilephaseAwas0.01mol·L-1potassi-um dihydrogen phosphate (adjusting pH to 2. 2 with phosphoric acid) and mobile phase B was acetonitrile with gradient elution,and the flow rate was 1. 0 ml· min-1 . The detection wavelength was 215nm,the column temperature was 40℃,and the injection volume was 20 μl. Results:The linear range of enalaprilat,enalapril maleate and eanlapril diketopiperazine was 14.64-43.92 μg·ml-1(r =0. 999 8), 9. 29-27. 87 μg·ml-1(r=0. 999 1)and 10. 80-32. 40 μg·ml-1(r=0. 999 5), respectively. Enalaprilat was not detec-ted out and enalapril diketone was 0. 2% using the method described in Chinese pharmacopeia, and the content of enalaprilat was 0. 1% and that of enalapril diketone was 0. 2% using the gradient elution. The related substances and enalapril maleate could be sepa-rated well. Conclusion:The method is sensitive, accurate and highly specific in the quality evaluation and control.

In the present study, we observed the effects of cholinergic enhancement by pyridostigmine (PD), a cholinesterases inhibitor, on GH release in both normal (n = 13) and GH deficient children and adolescents (n = 8). Responses of GH to insulin hypoglycemia were also observed. In the normal subjects, PD-induced serum GH peak levels were significantly higher than that induced by insulin (P

Objective:To study the expression and clinical significance of GPRC5A and SOCS3 in colorectal carcinoma.Methods:SP immunochemical method was performed to detect the expression of GPRCSA and SOCS3 in 45 cases of colorectal carcinoma,25 cases of colorectal adenomas and 22 cases of normal colorectal tissues.Results:1)Expression of GPRC5A in colorectal cancinoma tissue (22.2％) was significantly lower than that in adenomas tissue (52.0％,P＞0.05).The Latter was significantly lower than that in normal colorectal tissue (81.8％,P＜0.05).GPRC5Awas closely related to lymph node metastasis,Duke's stages and the deepness of invasion (P＜0.05).2) Expression of SOCS3 in colorectal cancinoma tissue (24.4％) was significantly lower than that in adenomas tissue (56.0％,P＜0.01).The Latter was significantly lower than that in normal colorectal tissue (86.4％,P＜0.05).SOCS3 was closely related to pathological differentiation,the deepness of invasion,Duke's stages and lymph node metastasis (P＜0.05).3)The expression of GPRC5A was positive correlated with SOCS3 (P＜0.05).Conclusions:The reduced expressions of GPRC5A and SOCS3 may participate in the occurence and development of colorectal carcinorma,suggesting that GPRC5A and SOCS3 may act as biological markers for evaluating the malign degree,prognosis and therapeutic targets of colorectal carcinorma.

Objective To investigate the infection of human papilloma virus(HPV) and expression of serum squamous cell antigen (SCCAg) in the follow - up of 120 cervical squamous carcinoma patients who had received operation or operation combined with radiotherapy or only radiotherapy. Methods 120 cases of therapical cervical squamous carcinoma patients were detected HPV - DNA by HC - Ⅱ and serum SCCAg using immunohistochemical method. Results The positive rate of HPV - DNA and serum SCCAg was 49.17% and 17.50% , with a significant difference between them( P 0.05 ). Conclusion HPV - DNA test with HC - Ⅱ for follow - up of cervical squamous carcinoma patients was feasible. It was more sensitive than serum SCCAg. But it suggested that high risk type HPV -DNA test combined with serum SCCAg may be the independent prognostic factors.

Objective The current study was to investigate the clinical and pathological features of macroscopic hematuria associated acute kideny injury (MH-AKI) in patients with IgA nephropathy (IgAN) and its associated prognostic factors.Methods We performed an analysis on the clinical and pathological features of biopsy-proven IgAN patients diagnosed during 2004 to August of 2007,who had experienced MH associated AKI.The patients enrolled in the study were followed up.The renal lesions were evaluated with Katafuchi pathological scores of IgAN.Results 5 patients with IgAN had experienced at least one episode of MH-AKI,accounting for 1.3% of IgAN diagnosed during the same period and 13.5% of IgAN patients with macroscopic hematuria.High proportion of tubules filled with red blood cell casts and tubular injury were demonstrated in all biopsy specimens.Renal function of 3 patients completely recovered within 14 days.One patient (patient 4) got quick recovery in the first month of the disease but completely recovered 418 days later.The other patients only had an incomplete recovery during the 20-month follow-up.The incompletely recovered one had relatively an older age,longer persistence of MH,more sclerotic glomeruli and a more severe tubule-interstitial damage.Conclusion AKI is commonly seen during episodes of MH in patients with IgAN.Not all patients with MH-AKI showed a complete recovery.Age,duration of MH,proportion of glomerular sclerosis and the severity of tubular necrosis might be the risk factors of an incomplete recovery of renal function.
