Objective To evaluate the efficacy of narrow-band ultraviolet B (NB-UVB) for the treatment of early-stage mycosis fungoides (MF).Methods A retrospective study was performed on 98 patients with early-stage MF treated with NB-UVB from January 2003 to December 2013.The rate of and time to recurrence of MF were assessed,and long-term side effects were evaluated in these patients.Results Among 52 patients achieving complete remission,the median number of sessions of NB-UVB radiation was 30 (range,18-87),the median cumulative radiation dose was 24.16 J/cm2 (range,9.11-108.86 J/cm2),and the median follow-up duration was 41 months (range,11-90 months).Relapse occurred in 14 (26.9％) patients with the median time to recurrence being 8.2 months (range,3-60 months).The patients suffering from relapse achieved complete remission after treatment with NB-UVB again.Adverse reactions mainly included skin erythema and itching at the early stage of radiation,as well as temporary pigmentation after radiation.Cutaneous carcinoma occurred in none of these patients during 11-90 months of follow-up.Conclusions NB-UVB phototherapy appeared to be effective for the treatment of early-stage MF,and no cutaneous carcinoma occurred in these patients during the follow-up.Although MF may relapse in some cases,repeated NB-UVB phototherapy is still effective.

Objective To explore the potential of converting the chloramphenicol resistant clinical E. Coli isolates to chloramphenicol sensitive ones by employing external guide sequence(EGS) technique in vitro. Methods Recombinant plasmids with EGScat 1+2 and tetracycline resistant gene, named PAlterl EGScat1+2, was constructed. Routine Cacl 2 method was used to introduce recombinant plasmid into the chloramphenicol resistant clinical isolates E. Coli 4758. Colony PCR was used to test and A600 was used to detect growth rates in liquid and solid culture of various concentrations of chloramphenicol. Results The chloramphenicol resistant clinical isolates E. Coli 4758 grew well in chloramphenicol(35 ?g/ml, 70 ?g/ml, 105 ?g/ml, 170 ?g/ml) plates whereas the transformants tE4758 with PAlter1 EGScat 1+2 failed to grow in these concentrations, which indicated its resistance to the chloramphenicol was reversed. Conclusions EGS molecules are able to convert the drug resistance in clinical E. Coli isolates in vitro.

To determine the relationship between Barrett's esophagus (BE) and features of gastroesophageal acid reflux, 24 h esophageal pH monitoring was performed in 90 patients. The patients were divided into 3 groups: 31 subjects with BE, 21 with mild esophagitis and 38 with severe esophagitis. The following parameters were evaluated: the percentage time of pH < 4; the number of reflux episodes over 5 min; the duration of longest episodes and DeMeester score over total period and the auterior three parameters in erect and supine position. All these parameters in BE were significantly different from those with mild esophagitis (P < 0.01) and not significantly different from those with severe esophagitis (P > 0.05). During supine position all the above parameters in BE were significantly different from those with reflux esophagitis (P < 0.05). It is concluded that the quantity of acid reflux is not an important factor in development of BE in gastroesophageal reflux (GER), and the acid reflux in supine position might be important in development of BE in GER.

The effects of mycophenolic acid (MPA) on high glucose-induced expression of transforming growth factor-beta (TGF-beta) and connective tissue growth factor (CTGF) in mesangial cells (MC) were investigated. Rat MC were cultured in the presence of different concentrations of MPA (1.0 and 10.0 micromol/L) or MPA plus high glucose for 72 h. The expression of TGF-beta and CTGF was detected by Western blot. The results showed that high glucose could induce the expression of TGF-beta and CTGF in MC, but MPA could inhibit this effects. MPA did not influence the expression of TGF-beta and CTGF in normal glucose. It was concluded that MPA might prevent the progression of diabetic nephropathy by inhibiting the expression of TGF-beta and CTGF in MC.

Objective To evaluate the efficacy of fluoroscopy-guided intercostal nerve radiofrequency coagulation in treating postherpetic neuralgia. Methods A total of 40 patients with postherpetic neuralgia (VAS ≥ 4.0) were randomly and equally divided into two groups. Patients in group A (control group) were treated with gabapentin, amitriptyline and oxycodone, while patients in group B (study group) were treated with intercostal nerve radiofrequency coagulation together with the same medicines used in group A. VAS score and oxycodone dosage were determined before the treatment and one, 7, 30, 90 and 180 days after the treatment. The side effects and complications during the treatment were recorded. The results were analyzed and compared between the two groups. Results The VAS scores of patients in group A and group B before the treatment and one, 7, 30, 90 and 180 days after the treatment were (8.2 ± 1.6) vs (8.1 ± 1.1), (6.1 ± 1.7) vs (4.5 ± 1.2), (4.2 ± 1.4) vs (2.7 ± 1.4), (3.6 ± 1.1) vs (2.3 ± 1.3), (3.3 ± 1.3) vs (1.6 ± 0.9), and (2.7 ± 1.2) vs (1.3 ± 1.0), respectively (P<0.05 in all), while the oxycodone dosages in group A and group B were (28.5 ± 5.4) mg vs (28.7 ± 5.8) mg, (35.2 ± 8.5) mg vs (17.3 ± 5.4) mg, (1.6 ± 8.5) mg vs (12.3 ± 3.8) mg, (18.6 ± 4.4) mg vs (5.1 ± 1.7) mg, (10.4 ± 2.3) mg vs (5.6 ± 1.1) mg, and (8.4 ± 1.6)mg vs (4.0 ± 1.1)mg, respectively (P < 0.05 in all). The drug side effects in group B were obviously very mild, and no serious complications occurred. Conclusion Fluoroscopy-guided intercostal nerve radiofrequency coagulation can rapidly relieve the pain in patients with postherpetic neuralgia, and reduce the oxycodone dosage and the occurrence of drug-related side effects as well. Therefore this technique is a safe and effective method for postherpetic neuralgia.
