Phosphate-dissolving microorganisms are widely distributed in soil, rhizosphere and other ecological environment. Understanding the characteristics of these microorganisms in solubilizing phosphates is helpful to apply them in improving P use efficiency. The obtained results indicated that the fungi had much higher capacity to dissolve the rock than the bacteria. Existence of Fe, Al, Mg and Na in the culture media reduced the rock solubilization by the bacteria, but increased the solubilization of the fungi. The higher content of the rock in the media, the lower capacity of the rock phosphate solubilization was found. The capacity was also significantly reduced if the concentration of C material in the media was higher than 3%. It was also found that the microorganisms destroyed the rock structure. The P was more easily released from the rock at further incubation. In conclusion, there is some potential to utilize the microorganisms to activate the rock phosphate.

Xanthine oxidase (XOD), catalyzing purine metabolism, is the key enzyme in uric acid (UA) biosynthesis, and becomes an important target for hyperuricemia treatment. The inhibition on XOD plays an important role in the treatment of hyperuricemia-related diseases, such as gout, as well as oxidative stress-induced tissue injury. Here, studies on the natural products with XOD inhibition are reviewed.

? AlM: To evaluate the efficacy of the method of vitrectomy combined with posterior sclera reinforcement for retinal detachment due to macular hole in high myopia.
?METHODS:From January 2012 to December 2013, in 45 eyes of 45 high myopic patients with retinal detachment due to macular hole, 28 eyes were in group A of vitrectomy with posterior sclera reinforcement and 17 eyes were in group B of vitrectomy. Preoperative examinations included visual acuity, intraocular pressure, indirect ophthalmoscopy and OCT were performed. ln follow - up 6 to 12mo, postoperative examinations of visual acuity, OCT were performed and effects of retinal reattachment and macular hole closure were compared between the two groups.
?RESULTS: ( 1 ) Postoperative examinations: visual acuity was 1. 19±0. 39 in group A and 1. 51±0. 34 in group B. The differences were statistically significant(P<0. 05). (2) The retinal reattachment rate was 100% in group A and 88. 24% in group B. There was no statistical significance between them(P>0. 05). (3) The macular hole closure rate was 82% in group A and 53% in group B. The differences were statistically significant(P<0. 05).
? CONCLUSlON: The treatment of vitrectomy with posterior sclera reinforcement is safe and feasible, which could improve visual acuity and increase the rate of macular hole closure in treating retinal detachment due to macular hole in high myopia.

OBJECTIVETo explore lupus nephritis (LN) patients' monocyte chemotactic protein 1 (MCP-1) and urinary IP-10 (ulP-10) levels, the correlation between each clinical activity index and rheumatism syndrome, thereby proving objective evidence for microscopic typing of rheumatism syndrome.

METHODSTotally 60 LN patients were assigned to the rheumatism group (31 cases) and the non-rheumatism group (29 cases). Besides, 20 healthy volunteers were recruited as the normal control group. Clinical data and renal pathology were collected, and urinary levels of MCP-1 and IP-10 detected by ELISA. The correlation between rheumatism syndrome and each activity index as well as manifestations of clinical activities was comprehensively analyzed. Results (1) Patients in the rheumatism group were more liable to occur fever, serositis, edema, and hypertension (P<0.05). (2) Compared with the non-rheumatism group, patients in the rheumatism group exhibited much higher levels of 24 h protein quantification and blood urea nitrogen, higher levels of uMCP-1 and ulP-10. Microscopic hematuria, anti-ds-DNA, anti-Sm, the positive rate of AnuA, scores of SLEDAI and BILAG were higher in the rheumatism group than in the non-rheumatism group (P<0.05). Levels of plasma albumin and complement C3 were lower in the rheumatism group than in the non-rheumatism group (P<0.05). (3) The average activity index (AI) of the renal pathology was higher in the rheumatism group than in the non-rheumatism group. The most frequent pathological type of rheumatism group was type IV of LN.

CONCLUSIONSMore severe renal damage and immune abnormality occurred in LN patients of rheumatism syndrome. Rheumatism syndrome is closely correlated to clinical activity indices.

ResultsEleven flaps survived.One case met with partial necrosis.The follow-up time ranged from 3 to 6 months(average of 4.5 months).The finges had good appearance.Ten cases had gained full postoperative sensory recovery and the two-point discrimination was 4-Smm at 3 months after operation.ConclusionUsing the flaps pedicled with digital artery perforator is a feasible solution for treatment of fingertip defects.

Objective To explore the clinical efficacy and side effects of paclitaxel combined with cisplatin chemotherapy for patients with locally advanced cervical cancer. Methods From May 2008 to May 2009,78 patients with locally advanced cervical cancer in our hos-pital were randomly divided into PF group (39 cases) and Taxol group (39 cases). Patients from PF group were treated with cisplatin com-bined 5-Fu while patients in Taxol group were cured with paclitaxel combined with cisplatin. After chemotherapy,all patients were given anes-thesia extensive hysterectomy and pelvic lymph node dissection. The clinical efficacy,side effects and three-year survival of 2 groups were as-sessed and compared. Results The main adverse reactions of PF group were gastrointestinal reactions,oral mucositis and bone marrow sup-pression;the major side effects of Taxol group were bone marrow suppression,oral mucositis and renal toxicity. After chemotherapy,the com-plete remission rate of Taxol group reached 30. 77%,which was higher than that of PF group 10. 26% (χ2 =5. 032,P=0. 025). The average survival time of PF group and Taxol group were 33. 5 months and 34. 7 months,the three-year survival were 59. 6% and 70. 2%,respectively (χ2 =1. 859,P=0. 173),and the difference was not statistically significant. Conclusion The adverse effects of different chemotherapy were observed in 2 groups. The clinical efficacy of Taxol group were better than that of PF group.

Objective To evaluate the effect of isoflurane anesthesia on noise-induced hearing loss in guinea pigs.Methods Forty-eight healthy adult male guinea pigs,aged 3 months,weighing 400-500 g,were randomly divided into 4 groups (n =12 each) using a random number table:control group (C group),isoflurane group (I group),noise-induced hearing loss group (N group),and isoflurane + noise-induced hearing loss group (I + N group).Isoflurane was inhaled for 140 min at a concentration of 1％ in I and I + N groups.N and I + N groups were exposed to the noise of 4 kHz center frequency and 118-122 dB sound pressure level for 120 min starting from 20 min after administration.Mean arterial pressure (MAP) was recorded at 10,40,70,100 and 120 min of exposure to noise and cochlear blood flow (CoBF) was recorded before administration and at 10,40,70,100 and 120 min of exposure to noise.Auditory brainstem response (ABR) threshold was recorded before administration and at 1 h,72 h,and 10 days after the end of exposure to noise.Arterial blood samples were obtained and the plasma noradrenaline (NE) concentration was detected by HPLC before exposure to noise and immediately after the end of exposure to noise.Results Compared with group C,MAP and the change rate of CoBF were significantly decreased,and the plasma NE concentration was increased immediately after the end of exposure to noise in I group,and MAP was increased,the change rate of CoBF was decreased,and the plasma NE concentration immediately after the end of exposure,and ABR threshold after the end of exposure were increased in N and I + N groups.Compared with N group,MAP was significantly decreased,the change rate of CoBF was increased,the plasma NE concentration immediately after the end of exposure,and ABR threshold at 1 and 72 h after the end of exposure were increased,and no significant was found in ABR threshold at 10 days after the end of exposure in I + N group.Conclusion Isoflurane anesthesia exerts temporary but not permanent protective effects against noise-induced hearing loss in guinea pigs and partial inhibition of activation of sympathetic nerve and increased CoBF may be involved in the mechanism.
