Objective To evaluate the pain control, general condition and well-being of the patients with advanced cancer treated with transdermal fentanyl as well as the effects of transdermal fentanyl on heart rate variability (HRV) and endocrine function. Methods This open prospective study included 40 patients with advanced cancer. The direct conversion ratio from oral morphine to transdermal fentanyl system (TFS) was 100:1 daily. In patients who had never received any opioid before the initial dose of TFS was 25?g/h. The transdermal system was changed every 72h and the dosage was adjusted to the need of the patients according to the VAS scores and the requirement of morphine. 8 hospitalized patients were monitored by 24h Holter for changes in HRV. Blood samples were taken before transdermal fentanyl patch when pain was severe and 24h after TFS for determination of ACTH,?-endorphin, growth hormone(GH) and insulin levels.Results Pain relief during treatment with transdermal fentanyl was significant accoring to VAS scores. Well-being scores showed that patients' quality of life including appetite, sleep, mental state and daily activities was significantly improved after two weeks treatment. The ratio of LF vs HF, which is one of HRV frequency indices, was obviously reduced at 24h after transdermal fentanyl patch as compared with that before TFS (P

Objective To investigate the influence of genital tract cytomegalovirus and chlamydia infection on the incidence of tubal pregnancy. Methods Ninety five women with tubal pregnancy (study group) and 42 women with ovarian cysts (control group) were selected for this study. Serum cytomegalovirus (CMV) IgM was identified by enzyme link immunosorbent assay (ELISA). Cervical secretions, endometrium, and salpinx tissue were tested for CMV gH gene and chlamydia heat shock protein (HSP) gene by nest polymerase chain reaction (PCR) and PCR respectively. Results CMV IgM was positive in 14 (15%) women with tubal pregnancy, and 1 (2%) in the control group. CMV gH gene was detected in 18 women (19%) and chlamydia HSP gene in 25 (26%) of the tubal pregnancy group, and 2 (5%) and 2 (5%) in the control group respectively. There were significant differences between the study and the control group ( P

The B.subtilis ywtD gene,encoding a ?-polyglutamic acid(?-PGA)depolymerase,was amplified from the genome of B.subtilis NX-2 by PCR.The comparability between the cloned ywtD gene sequence to the reported sequence is high to 99.0%.Only one of the substituted nucleotide base caused the change to the amino acid sequence.The recombinant plasmid pET-15b-ywtD was then transformed into E.coli Rosetta(DE3)and the ywtD gene product could be expressed with the induction of 0.5mmol/L IPTG.The YwtD protein exhibited a remarkable activity in ?-polyglutamic acid degradation.The molecular weight of ?-PGA could be reduced from 700kDa to 20kDa after 72h through the enzymatic hydrolysis and consequently trended to be constant.

Objective To evaluate the clinical efficacy and safety of different courses of topical tacrolimus 0.1％ ointment in facial corticosteroid-dependent dermatitis and to observe the rebound in patients after treatment with these regimens.Methods A total of 104 patients with facial corticosteroid-dependent dermatitis were randomly divided into 3 groups to be treated with topical tacrolimus 0.1％ ointment twice daily for 4,8 and 16 weeks respectively.The patients were followed up every 2 weeks within the early 4 weeks of treatment and every 4 weeks thereafter.The rebound phenomena was observed in patients on week 4 after the withdrawal of tacrolimus.Results Finally,90 patients completed this trial,including 32 patients in the 4-week group,29 patients in the 8-week group and 29 patients in the 16-week group.No significant differences were observed between the 4-,8- and 16-week groups in the total reponse rate (75.00％,82.76％,86.21％,respectively,x2 =1.35,P ＞ 0.05).The rebound rate in the 16-week group significantly differed from that in the 4- and 8-week group (20.69％ vs.46.88％ and 41.38％,both P＜ 0.05),while no statistical difference was noted between the 4- and 8-week groups.Local burning and itching were reported in 31.73％ of these patients,and all of these irritant reactions occurred within the first week of treatment.Conclusions Topical tacrolimus 0.1％ ointment is safe and effective for the treatment of facial corticosteroid-dependent dermatitis.The total response rate does not increase with the extended treatment course,and 4 weeks of treatment is enough for the marked and stable improvement of facial corticosteroid-dependent dermatitis,but the rebound rate is likely to be reduced by extended treatment course.

OBJECTIVETo compare the clinical therapeutic effects on intractable facial paralysis among acupuncture, acupoint catgut embedding and PDS embedding.

METHODSTwo hundred and seventy-nine patients of intractable facial paralysis were randomized into an acupuncture group, a catgut embedding group and a PDS embedding group, 93 cases in each one. Cuanzhu (BL 2), Yuyao (EX-HN 4), Taiyang (EX-HN 5), Xuanlu (GB 5), Dicang (ST 4), Jiache (ST 6), Quanliao (SI 18), Qianzheng (Extra), Xiaguan (ST 7) and Fengchi (GB 20) on the affected side and bilateral Hegu (LI 4) and Zusanli (ST 36) were selected in the three groups. In the acupuncture group, acupuncture was applied to those acupoints, once every two days; 10 treatments made one session; the successive three sessions were required. In the catgut embedding group and the PDS embedding group, catgut and PDS were embedded separately, once every 10 days; 3 treatments made one session and the successive two sessions were required. The therapeutic cycle was 2 months in the three groups. The therapeutic results were analyzed statistically 2 months later. The scores of Sunnybrook facial nerve grading system and the facial nerve electroneurography (ENoG) were used for the efficacy assessment before and after treatment in the three groups.

RESULTSAfter treatment, the score of Sunnybrook facial nerve grading system was improved apparently after treatment as compared with that before treatment in any of the three groups (all P < 0.05). The score in either of the embedding groups was better than that in the acupuncture group (both P < 0.05). The difference was not significant between the catgut embedding group and the PDS embedding group (P > 0.05). After treatment, ENoG wave ampli tude values in the frontal muscle and orbicularisoris muscle on the affected side were improved as compared with those before treatment in the three groups (all P < 0.05). Those in the catgut embedding group and the PDS embedding group were better than those in the acupuncture group (all P < 0.05), and had no significant difference as compared with those on the healthy side (P > 0.05). In the acupuncture group, ENoG wave amplitudes on the affected side were lower than those on the healthy side (both P < 0.05).

CONCLUSIONAcupuncture, catgut embedding and PDS embedding at acupoints all achieve the therapeutic effects on intractable facial paralysis. However, the acupoint embedding therapy presents more advantages on the recovery of facial nerve function. The efficacy is similar between the catgut embedding and the PDS embedding.

Objective To explore the clinical features of drug hypersensitivity syndrome(DHS). Method Retrospective analysis of 18 cases of DHS was made in detail including clinical situation, laboratory examination, treatment instance,duration and prognosis. Results The earliest symptoms of all patients were skin rash and fever, which occurred in 2 to 8 weeks after the administration of the drugs, accompanied with superficial lymphadenopathy in 13 patients, liver dysfunction in 14 patients, renal impairment in 11 patients, leukocytosis in 13 patients and eosinophilia in 10 patients. The skin lesions were multiform. The common eruption was purpura-like erythemas, accompanied with swelling and repeated desquamation. The suspected drugs were as follows: allopurinol in 11 cases, carbamazepine in 4 cases, phenytoin in 2 cases and minocycline in 1 case. Corticosteroid was the first line of treatment Conclusions DHS is a clinical syndrome to have characteristic symptom and a relatively severe disease. It is crucial to discontinue the suspected drugs promptly and to start sufficient dose of corticosteroid.
