Ergosterol is the important component of the fungal membrane, and having stable structure. This makes it a suitable indicator for growth of fungi. In the paper, isolation and determination techniques of ergosterol as the indicator of the fungal biomass were reviewed. The methods of extracting ergosterol include traditional saponification and refluxing, rapid physical disruption, rapid ultrasonication, supercritical fluid extraction and so on. The ergosterol determination methods are high performance liquid chromatography, gas chromatography-mass spectrometry, liquid chromatography-mass spectrometry, and thin-layer chromatography, et al. The application of these techniques was also introduced. Finally, the paper prospected the feasibility of applying the ergosterol as the indicator of fungal biomass in composting.

OBJECTIVETo evaluate the efficacy and safety of Bushen Qiangji Granule (BQG) in treating ankylosing spondylitis (AS) patients with Shen-deficiency and blood-stasis syndrome.

METHODSA randomized controlled and single-blinded prospective clinical trial was carried out on 68 patients, who were randomly assigned into the BQG group treated with BQG alone and the combined treated (CT) group treated with BQG and sulfasalazine, six-month medication was successively applied to both groups. The therapeutic effects were evaluated before treatment and at the end of the 1st, 3rd and 6th month of the treatment.

RESULTSThe total effective rate was 81.82% in the BQG group and 86.82% in the CT group after 6 months of treatment, showing no significant difference between the two groups, but that after 1 months of treatment in the BQG group was lower than that in the combined group (15.15% vs. 27.59%, P < 0.01). Bath AS disease activity index (BASDAI), Bath AS function index (BASFI), and clinical symptoms such as ache and morning stiffness, as well as indexes of Schober test, activity of thoracic cage, finger-ground distance, erythrocyte sedimentation rate (ESR) and Creactive protein (CRP) in both groups were improved remarkably. BQG showed a time-dependant' effect, the therapeutic effect intensified as the time went by (P < 0.05 or P < 0.01). Moreover, the effect initiating time was earlier in the CT group than that in the BQG group.

CONCLUSIONBQG has satisfactory efficacy, good safety and compliance, and is convenient for administering, therefore, it has broad applying prospect with high exploiting value.

ObjectiveTo investigate the development trend of drinking water type of endemic fluorosis in Qinghai province, and to provide the basis for the prevention and treatment of the disease. MethodsIn 2009, six monitoring counties were chosen by using simple random sampling methods, all diseased villages of the six monitoring counties were classified into light, moderate and severe disease types according to water fluorine content on the historical data, and 1 village was respectively chosen from each type. In monitoring villages with improved water, 3 tap water and one source water samples were collected, respectively. Five water samples were collected randomly in water unimproved monitoring villages according to water well locations of east, west, south, north and center. The fluorine content in water and urine was determined according to the Standard Testing Methods for Drinking Water (GB/T 5750-2006). Children aged 8 to 12 were examined for dental fluorosis by Dean method.Clinical osteofluorosis of all the resident over the age of 16 was examined, 2 village of these counties were randomly selected, and clinically diagnosed patients with skeletal fluorosis were examined again by X-ray using Diagnostic Criteria of Endemic Skeletal Fluorosis (WS 192-2008). Urine sample of 30 children aged 8 to 12 and of 20 adults over the age of 16 were randomly collected and urinary fluoride was determined by F-ion selective electrode method (WS/T 89-2006). ResultsImproving water projects had been implemented in 14 monitoring villages of the 18 villages in 6 counties, the rate of improved-water was 77.78％(14/18). Among the 14 projects, 5 improved-water projects ran normally, and 9 projects ran with intermittently water supply. Seventy-five water samples were tested, themean of water fluoride was 0.48 mg/L. The prevalence of dental fluorosis was 31.95％ (285/892), that of clinical skeletal fluorosis was 36.55％(1570/4295) and the X-ray detection rate of skeletal fluorosis was 25.64％ (20/78).Five hundred and seventy-one urine samples of children were determined, and geometric mean of urinary fluorine was 1.04 mg/L; 370 adult urine samples were determined, and geometric mean of urinary fluorine was 1.52 mg/L Conclusion Epidemic of drinking water type of endemic fluorosis is still serious in Qinghai province, and drinking water defluoride measures should be further strengthened and improved.

OBJECTIVETo retrospective study the results of arthroscopic resection of articular capsule valvular treated popliteal cysts and examined the incidence of complication.

METHODSFrom July 2007 to July 2010, 45 patients with symptomatic popliteal cysts such as knee pain and limitation of motion were treated with arthroscopic technique to resect the connecting valvular mechanism at posteromedial compartment of articular capsule. Through the posteromedial viewing portal and cyst resection working portal, resected the valvular mechanism by shaver and plasma cutter, associated intra-articular pathology was treated simultaneously. The functional outcome was evaluated by employed Rauschning and Lindgren score before the surgery and the last follow-up. By using of Wilcoxon rank sum test to statistics analyze the clinic outcome.

RESULTIn all cases, 40 patients were found the associated intra-articular pathology, the incidence was 88.9%.The intra-articular pathology was medial meniscus tear (27 cases, 60.0%), lateral meniscus tear (20 cases, 44.4%), cartilage lesion (28 cases, 62.2%), which composed with patellofemoral joint (12 cases, 26.7%),medial condyles of femur (10 cases, 22.2%),lateral condyles of femur (6 cases, 13.3%). The anterior cruciate ligment injury was found in 2 cases, the incidence was 4.4%. All the patients achieved symptoms relief postoperative, such as posterior knee discomfort and swelling after activities.The Rauschning and Lindgren score was improved 1-2 grade in average (Z = -6.092, P = 0.00). The recurrence rate was 2.2%. All the incision healed good. No major complications were encountered such as saphenous nerve, great saphenous vein, blood vessel in popliteal injury.

·AIM: To investigate the effect of sodium hyaluronate eye drops on ocular inflammatory response and dry eye after phacoemulsification combined with intraocular lenses (IOL) implantation for age-related cataract. ·METHODS: The clinical data of age-related cataract patients treated with phacoemulsification combined with IOL implantation in 200 cases (200 eyes) of our hospital from June 2016 to July 2017 were retrospectively analyzed. According to the different postoperative application of eye drops they were divided into observation group and control group (100 cases each). The observation group was given sodium hyaluronate eye drops and the control group was given tobramycin dexamethasone eye drops. The results of BUT,FL,proteins concentration in aqueous and ocular surface disease index (OSDI) score were compared before and at the first day,the seventh day and the fourteenth day after the operation. And the incidence of conjunctival hyperemia and ciliary hyperemia was compared between 1d after surgery and 14d after surgery. ·RESULTS: There was no significant difference in OSDI scores between the two groups before and at 1d after surgery (P>0.05). The OSDI score of the two groups was higher than that before the operation on the first, the seventh and the fourteenth day after surgery (P<0.05). The OSDI score of the two groups decreased gradually after reaching the highest level on the first day after surgery (P<0.05). The OSDI scores of the observation group on the 7 and 14d after surgery were lower than those in the control group (P<0. 05). There was no significant difference in the BUT between the two groups before and at 1d after surgery (P>0.05). The levels of BUT in the two groups were lower than those before operation on the first,the seventh and the fourteenth day after surgery (P < 0. 05). BUT levels in both groups increased gradually after reaching the lowest level on the first day (P<0.05), the levels of BUT in the observation group were higher than those in the control group on the 7 and 14d after operation (P< 0. 05). There was no significant difference in FL level between the two groups before and the first day after operation (P>0.05). The levels of FL in the two groups were different from those before operation (P<0.05) on the first, the seventh and the fourteenth day after operation (P<0.05). FL levels in the two groups decreased gradually after reaching the highest level on the first day after surgery (P<0.05), the levels of FL in the observation group on the 7th day and the 14th day after operation were lower than those in the control group (P < 0. 05). There was no significant difference in the incidence of conjunctival hyperemia and ciliary congestion between the two groups on the first day after operation (P>0.05); the incidence of conjunctival hyperemia and ciliary hyperemia in the two groups on the fourteenth day after surgery was lower than that on the first day after surgery (P<0.05). However, the incidence of conjunctival hyperemia and ciliary congestion on the fourteenth day after operation was significantly lower in the control group than in the observation group (P<0.05). Postoperatively 1,7,14d, aqueous humor protein concentration in the two groups of patients compared with preoperative had difference (P< 0. 05), and two groups of patients with aqueous humor at postoperatively 1d after reaching the highest protein concentration decreased ( P < 0. 05 ), aqueous humor protein concentrations of the control group 7,14d after operation were lower than the observation group (P<0.05). ·CONCLUSION: The effect of sodium hyaluronate eye drops on improving dry eye after age-related cataract phacoemulsification combined with IOL implantation is greater than that of tobramycin dexamethasone eye drops, but it is less effective for eye inflammation than tobramycin dexamethasone eye drops.After comprehensive consideration, for the patients with light inflammation, small incision phacoemulsification combined with IOL implant, sodium hyaluronate eye drops is a good selection.
