[Efficacy observation of fire needle combined with narrow band ultraviolet-B (NB-UVB) for vitiligo].

OBJECTIVE: To compare clinical efficacy difference between fire needle combined with narrow band ultraviolet-B (NB-UVB) and NB-UVB therapy for vitiligo. METHODS: Ninety-three cases of vitiligo were randomly divided into an observation group (n = 48) and a control group (n = 45). In the observation group, fire needle was applied to ashi points around the damaged skin and Zusanli (ST 36), meanwhile NB-UVB therapy irradiating the local area. The control group was treated by NB-UVB therapy. The clinical efficacy was evaluated after the treatment of 12 weeks. RESULTS: The total effective rate was 79.2% (38/48) in the observation group, which was superior to that 48.9% (22/45, P < 0.05) in the control group. CONCLUSION: The fire needle combined with NB-UVB for vililigo achieves a more obvious efficacy than NB-UVB therapy.

[Studies on nitrobacteria and nitrification in Liaohe estuary wetland sediments].

Nitrobacteria, nitrification and its impact factors were discussed based on the method of on-site incubation and laboratory simulation in Liaohe estuary wetland sediments in June and August 2009, respectively. The results showed that the number of ammonia-oxidizing bacteria (AOB) ranged from 0.54 x 10(4) to 5.69 x 10(4) cells x g(-1) with an average of (2.21 +/- 2.32) x 10(4) cells x g(-1) in June and ranged from 1.90 x 10(4) to 7.90 x 10(4) cells x g(-1) with an average of (3.61 +/- 2.87) x 10(4) cells x g(-1) in August. The potential nitrification rates ranged from 9.72 to 16.45 mmol x (m2 x h)(-1) with an average of (12.54 +/- 3.14) mmol x (m2 x h)(-1) in June and ranged from 14.66 to 24.62 mmol x (m2 x h)(-1) with an average of (18.71 +/- 4.21) mmol x (m2 x h)(-1) in August. The net nitrification rates were 0.41 mmol x (m2 x h)(-1) in June and ranged from 0.20 to 0.53 mmol x (m2 x h)(-1) with an average of (0.35 +/- 0.16) mmol x (m2 x h)(-1) in August. The potential nitrification rates were apparently higher than the net nitrification rates. The AOB abundance and nitrification rates were all higher in August than in June. Ammonia concentration in the overlying water, pH, organic matter, total nitrogen content, total phosphorus content, ammonia nitrogen content and the number of AOB in sediments were the main environmental impact factors on nitrification by SPSS 13.0 statistical analysis (p < 0.05), and it also showed ammonia concentration in the overlying water, total phosphorus content and ammonia nitrogen content in sediments were key impact factors on nitrification by partial correlation analysis. The flux of transformed ammonium into nitrate by nitrification process was 1.14 x 10(5) kg per day, suggesting that nitrification was important on nitrogen cycle in Liaohe estuary wetland sediments.

[Observation on the therapeutic effect of a red-hot needle therapy combined with blood-letting puncture and cupping for treatment of neurodermatitis].

OBJECTIVE: To search for an effective therapy for neurodermatitis. METHODS: Ninety-six cases were divided into 2 groups by random number table. The treatment group (n = 54) were treated by hot-red needle therapy combined with blood-letting puncturing and cupping at skin-injured area, and the control group (n = 42) were treated with external smearing of halometasone cream. RESULTS: The cured rate and the total effective rate were 51.9% and 96.3% in the treatment group, and 28.6% and 81.0% in the control group, respectively, with a significant difference between the two groups in the therapeutic effect (P < 0.05). CONCLUSION: Red-hot needle therapy combined with blood-letting puncture and cupping has a definite therapeutic effect on neurodermatitis, without toxic and adverse effects.
