The mechanism of chromium accumulation and microstructure transformation of the fused yeast were studied in this paper.The result showed that the process of Cr6+ reduction and adsorption was accom-panied by the H+ consumption.The main adsorptive groups on the strain surface included amino,hydroxyl,phosphate group and amide,among which phosphate group played vital role in the chromium accumulation.The removal rate of chromium and reduction rate of hexavalent chromium declined 70% and 46%,respec-tively,when phosphate group was masked.During the adsorption process the chromium ions complexed on the surface of fused yeast was transported into the cell wall and combined with inclusion to form steady spe-cies and this took 90 min to reach the equilibrium.The biosorption and reduction of Cr on the cell surface would alter microstructure of cell surface,reduce cell membrane potential and increase cell membrane per-meability.

Objective To present the experience in surgical treatment method and clinic application of axillary tuberculous lymphadenitis in infant.and discuss its etiology.Methods From 1995 to 2003, axillary tuberculous lymphadenitis mass in 14 hospitalized cases were resectioned.Results The incision healing was better in 3 cases of regional lymphadenectomy and 11 cases of axillary lyphoidectomy.The tuberculous lymphadenitis was not relapse during patients were followed-up.All discharge patients were not suffer from extrapulmonary and intrapulmonary tuberculosis.Conclusions The prompt regional lymphadenectomy and axillary lyphoidectomy are preferred to axillary tuberculous lymphadenitis and suspicious tuberculous lymphadenitis.It is effective to avoid the patients suffering from tuberculosis in other organs of human body and eliminate antituberculous drugs lesion to important organs of body.

In Western countries, more and more people select acupuncture and moxibustion as medical ways, and more and more acupuncture and moxibustion research organizations are set up. Britain TCM foundation is such one center for acupuncture research. This center is aimed at promoting acupuncture research. Since 1991, a series of clinical trials and several big research tasks have been completed. The clinical designs in the center are very careful and scientific, being worth to be learnt. In the paper, clinical studies in the center are introduced for increasing levels of acupuncture and moxibustion research at home.

The stability of microbial flocculant (MBF) produced by Aspergillus sojae and its application to municipal thickened sludge dewatering were studied. The results showed that the MBF had high heat and acid-base endurance with high flocculating activity in a wide range of pH from 1.5 to 12. The MBF retained 96% of flocculating activity after 35 days preservation at 4℃, but in different pH the flocculating activity difference was very apparent after 35 days store at room temperature. The experimental results also demon- strated that the MBF was better than PAM and PAC in reducing specific resistance filtration. The optimal dose of MBF used for intensifying thickened sludge dewatering is 7%(volume fraction). And the more the volume of sludge is treated, the less the cost of MBF for unit volume sludge treatment.

Keratoconus (KC) is a common cornea ectatic disorder characterized by myopia,irregular astigmatism and other visual impairment caused by corneal thinning and cone-shaped protrusion.With a wide range of effects,the etiology of this disease is unknown,and genetic factors may be involved in its pathogenesis.This paper summarizes the research progress on KC genetic etiology for reviewing the selected candidate genes and loci based on traditional/genome-wide linkage studies,genome-wide association studies and central corneal thickness in recent years.Genetic studies on KC pathogenesis will advance our understanding of this disease and further promote the development of potential therapies.

Mycoplasma hyopneumoniae (M .hyopneumoniae) and Mycoplasma hyorhinis (M .hyorhinis) infections are common in China .To investigate the prevalence of M .hyorhinis and M .hyopneumoniae in Jiangsu Province of China ,a mo-lecular epidemiological survey was conducted from 399 nasal swab samples of unvaccinated pigs using nested Polymerase Chain Reaction (nested PCR) .Nasal swab samples were collected from Jiangquhai porcine lean (JQHPL) strain pigs and other West-ern breeds .Clinical samples were taken from each pig and divided into different groups based on ages of pigs (7 ,14 ,21 ,28 , and 35 days) .Results indicated that the prevalence of M .hyorhinis was 70 .9% from different herds in Jiangsu Province in China ,while the prevalence of M .hyopneumoniae was 13 .5% .M .hyorhinis infection was more common in pigs for less than 5 weeks of age compared to M .hyopneumoniae infection .Co-infection was also observed in 30 samples (7 .5% ) in which both M .hyorhinis and M .hyopneumoniae were detected .The M .hyorhinis infection increased as the animals grew from 7 to 35 days .The M .hyopneumoniae infection did not change significantly as the pigs grew older .Significant difference of M .hyorhi-nis infection was observed between other Western breeds and JQHPL pigs (P<0 .001) .JQHPL pigs appear to be more sensi-tive to the M .hyorhinis infection as compared to the other Western breeds .However ,there is no obvious relationship between the breed type and M .hyopneumoniae infection (P>0 .05) .

OBJECTIVETo study the efficacy and safety of Eviprostat for the treatment of benign prostatic hyperplasia (BPH).
METHODSAn open, multicentral clinical trial was conducted in 100 patients with BPH. Patients received a 12-week oral administration of Eviprostat 2 tablets per-time, 3 times a day. The main indexes of efficacy include international prostatic symptom score (IPSS), maximum urinary flow rate (Qmax), residual urine ( Ru) and prostatic volume (V). The additional indexes are quality of life score (QOL) and average urinary flow rate (Qave).
RESULTSAfter a 12-week therapy, IPSS, QOL score, Qmax and Qave were significantly improved. IPSS was averagely decreased by 5.67 (P < 0.001); QOL score was averagely decreased by 1.44 (P < 0.001); Qmax was averagely increased by 1.70 ml/s (P <0.001); Qave was averagely increased by 1.15 ml/s (P < 0.001); Ru was averagely decreased by 5.07 ml (P = 0.046) , PSA level was averagely decreased by 0.129 microg/L (P < 0.017). The clinical adverse event rate was 1%.
CONCLUSIONEviprostat is a kind of safe, effective and preferable drug for treating BPH. It can improve the subjective symptoms and objective measures of the patients.

OBJECTIVETo observe the early bone integration of oral implants after injection of exogenous nerve growth factor (NGF) and investigate the effects of NGF on peri-implant osseointegration.
METHODSTwelve New Zealand white rabbits were used in this study to establish bi-mandible implant model. Then local injection of 1 µg NGF was given on the right side of the mandible as experimental group and normal saline only was injected on the left side as control group once a day for seven days. The rabbits were respectively sacrificed at 2, 4 and 8 weeks after surgery. The implant-bone grinding samples were prepared and stained by toluidine blue for general observation, X-ray, histology and bone histomorphometry analysis.
RESULTSThe density of the new bone around implants at 2 and 4 weeks was lower than normal bone. Compared with the control group, the quantity of new bone and bone-implant contact ratio significantly increased in the experimental group. At 8 weeks, the new bone density in both groups was similar to the normal bone. In the experimental group, the haversian system was observed. Bone contact ratio was significantly different between experimental and control group at 2 and 4 weeks, but similar at 8 weeks.[control group at 2 weeks (26.67 ± 3.88)%, 4 weeks (52.59 ± 5.07)% and 8 weeks (97.33 ± 6.75)%, experimental group at 2 weeks (42.24 ± 6.67)%, 4 weeks (72.25 ± 6.30)% and 8 weeks (99.15 ± 4.68)%].
CONCLUSIONSApplying exogenous NGF in the early phase could accelerate the formation and maturation of trabecular bone around the implants and shorten the period of osseointegration. Nerve growth factor could promote osseointegration in the early stage of oral implantation.
