Chinese Journal of Integrated Traditional and Western Medicine 2015;35(3):287-289
OBJECTIVETo observe the effect of Angong Niuhuang Pill (ANP) on Thl/Th2 in cerebral infarction patients and to explore the mechanism of phlegm-heat obstructing orifices.
METHODSRe- cruited were 30 cerebral infarction patients of phlegm-heat obstructing orifices syndrome (PHOOS) both in China and Indonesia. They were assigned to 4 groups according to the use of ANP, the Chinese treatment group, the Indonesia treatment group, the Chinese control group, and the Indonesia control group. Patients in the two control groups received conventional treatment, while those in the two treatment group additionally took ANP for 30 successive days. Their adverse reactions were observe, and levels of INF-γ and IL-4 were detected.
RESULTSThe INF-γ level and the INF-γ/IL-4 ratio significantly decreased, and the IL-4 level increased after treatment in the four groups with statistical difference (P < 0.05). Compared with the control group after treatment in the same country, the INF-γ level and the INF-γ/IL-4 ratio were lower, and the IL-4 level was higher in the two treatment groups (P < 0.05). Compared with the two Chinese groups, the INF-γ level and the INF-γ/IL-4 ratio were higher, and the IL-4 level was lower in the two Indonesian groups (P < 0.05). There was no statistical difference in the post-treatment indices between the two treatment groups.
CONCLUSIONSANP had moderating effect on Th1/Th2 in cerebral infarction pa- tients. Cerebral infarction patients of PHOOS might exist certain relation with Th1/Th2.

In the study, the inhibitory effect of epigallocatechin gallate (EGCG) on Calcium oxalate nephrolithiasis and its possible mechanism were investigated. The rat Calcium oxalate nephrolithiasis model was induced through the combined oral administration of ethylene glycol and ammonium chloride, which was intervened with EGCG. Rat blood samples were collected to detect blood creatinine (Cr), blood urea nitrogen (BUN) and blood calcium. Rat urine samples were collected to observe and compare 24-hour urine volume, oxalic acid (Ox) and calcium in urine. Renal samples were collected to prepare tissue slices and observe the pathological changes in Calcium oxalate nephrolithiasis. The expression of osteopontin (OPN) in renal tissues was evaluated by Real-time PCR and Western blot. According to the results, compared with normal rats, rats in the nephrolithiasis model showed significant increases in Cr, BUN, urine Calcium, urine Ox and renal OPN expression (P < 0.05), but obvious decrease in 24-hour urine volume (P < 0.05); Compared with rats with nephrolithiasis, those processed with EGCG revealed remarkable declines in Cr, BUN, urine Calcium and urine Ox (P < 0.05), with significant rise in 24-hour urine volume (P < 0.05) in a concentration-dependent manner. Additionally, compared with the control group, nephrolithiasis rats showed significant pathological changes in Calcium oxalate calculus. After ECCG treatment, the renal pathological changes and OPN expression attenuated significantly in a concentration-dependent manner. The results showed that EGCG inhibits the formation of calcium oxalate nephrolithiasis in rats and shows a notable protective effect on renal functions.

Objective To arthroscopically re-observe the remodeling and maturity process following anterior cruciate ligament(ACL) reconstruction with a hamstring tendon autograft.Methods Thirty-three patients who had undergone a previous arthroscopic ACL reconstruction with a homolateral hamstring autograft were given a second observation under arthroscope.The interval from initial reconstruction to second-look arthroscopy ranged 2~36 months(mean,11.9 months).According to different intervals,the patients were grouped as 1~,4~,7~,10~,13~,18~,and 25~ months.The shape,color,tension,covering synovial tissue,and vascularity of the grafts were evaluated.Results As the interval increased,the hamstring grafts tended to progress to normal ACL morphologically.Under arthroscopic observation,the tendon grafts were characterized as grayish-white thick ligamentous tissues without synovial membrane and blood vessels after 7 months following initial reconstruction,which corresponded with the maturation period of autogenous grafts and simulated normal ACL.Conclusions Remodeling and maturation of the hamstring autografts progresses with time,which is comparable to patellar tendon autografts.

Objective To investigate the gene therapy of hypoparathyroidism (HPT) with hemopoietic stem cell s(HSCs) integrated with parathyroid hormone (PTH) gene.Methods Human PTH gene was amplified by polymerase chain reaction from pcDNA 3.1 -PTH templates and inserted into murine stem cell virus (MSCV) vectors. The plasmids recombinated with PTH gene were transfected into PA317 packaging cells and screened for positive clones with Geneticin. The condensed recombinant retroviruses were obtained and used to infect HSCs coming from umbilical cord blood. The infected HSCs were injected into the mice suffering from HPT. The change of symptoms and serum level of PTH and calcium in each group of mice was observed.Results Human PTH gene was proved to be inserted into MSCV vectors and the titres were up to 2?10 7 colony forming unit (CFU)/ml in condensed retroviral solution. The secretion of PTH reached 15 ng per 10 6 cells per 48 h. The wild type viruses were not detected by PCR amplification. The mice suffering from HPT recovered quickly and the serum level of calcium and PTH remained normal for about 3 months after the HSCs recombinated with PTH gene were injected into them. In the groups of mice subject to the injection of the recombinant retroviruses containing PTH gene, the serum level of PTH and Calcium was significantly increased in a short time, and then declined slowly. And the mice took on the manifestation of hypoparathyroidism again. The mice only subject to the implantation of HSCs were all dead within 20 days.Conclusion A long term therapeutic effect could be obtained by infusing the HSCs which were integrated with PTH gene into the mice suffered from hypoparathyroidism.
