2.Treatment of minimal hepatic encephalopathy
Journal of Clinical Hepatology 2014;30(10):1094-1096
Minimal hepatic encephalopathy (MHE)is defined as early hepatic encephalopathy without grossly evident neurologic abnormali-ties,but with cognitive deficits that can be revealed by psychometric testing.However,numerous studies have shown a lack of obvious clini-cal manifestations in MHE patients,and there is no international unified diagnostic gold standard for this disease.Affected patients′quality of life and ability to work are markedly impaired,and some even gradually progress to symptomatic hepatic encephalopathy.The treatment methods for MHE mainly include eliminating the precipitating factors for this disease and medication.This review presents the options for treatment of MHE and gives an objective evaluation of the efficacy of each treatment scheme.Currently,several treatment methods are used together,but no studies have demonstrated that combined use of treatment methods can improve the treatment outcome.
3.Two cases of bullous pemphigoid after long-term treatment with toripalimab
Chinese Journal of Dermatology 2021;54(2):131-135
Case 1, a 63-year-old female patient presented with blisters and bullae arising in erythema all over the body with itching for 2 months. Two years ago, the patient underwent peri-intestinal lymph node dissection for the treatment of malignant melanoma of the rectum and anal canal, and received intravenous injection of toripalimab for preventive treatment for 1 year, and generalized skin lesions occurred 2 weeks after drug withdrawal. Direct immunofluorescence testing of erythema on the upper extremities showed that immunoglobulin G (IgG) was deposited along the basement membrane zone; salt-split indirect immunofluorescence testing of a serum sample showed liner deposition of IgG in the epidermis. Enzyme-linked immunosorbent assay (ELISA) revealed that the serum level of anti-BP180 antibodies was over 200 U/ml. The patient was diagnosed with bullous pemphigoid, but it was doubtful whether the disease was caused by PD-1 inhibitor toripalimab or not. Then, the patient received oral minocycline at a dose of 200 mg/d and prednisolone acetate at a dose of 20 mg/d, and topically applied halometasone cream all over the body. After half-a-month treatment, the blisters crusted over and the erythema darkened in color. Case 2, a 36-year-old female patient presented with generalized blisters and itching for more than 3 months. The skin lesions manifested as tense blisters, bullae, bloody bullae and crusts on the edematous erythema. The patient had a 3-year history of vaginal malignant melanoma, which was stage Ⅳ postoperative melanoma with local recurrence and lymph node metastasis nearby the right iliac vessels. After 2-year treatment with intravenous injection of toripalimab, generalized skin lesions occurred all over the body. Direct immunofluorescence testing of the erythema showed weakly positive staining for IgG, and linear deposition of IgG along the basement membrane zone; salt-split indirect immunofluorescence testing of a serum sample showed liner deposition of IgG in the epidermis. ELISA revealed that the serum level of anti-BP180 antibodies was over 200 U/ml. The case 2 was diagnosed with bullous pemphigoid, but it was also doubtful whether the disease was caused by PD-1 inhibitor toripalimab or not. Then, the case 2 was treated with oral doxycycline at a dose of 200 mg/d and oral prednisolone acetate at a dose of 40 mg/d. After 2-week treatment, the blisters completely crusted over and erythema darkened in color.

Objective To study the volume of total prostate and the volume of its transitional zone in different age groups of elderly men. Methods 213 elderly men of 50 to 79 years of age from a community of Beijing city were divided into 3 groups and studied. The volume of total prostate and the volume of the transitional zone were measured by rectal ultrasonography and the index of the transitional zone was calculated. All the data were evaluated with statistical analysis. Results The number of subjects in the 50~59 age group was 75,in the 60~69 age group 81 and in the 70~79 age group 57.The volume of total prostate was 23.82?8.83,29.16?10.01 and 33.77?11.74 respectively and the transitional zone 1.52?1.19, 3.60?3.66 and 7.25?7.02ml respectively. The index of transitional was 0.10?0.12, 0.13?0.11, 0.20?0.11 respectively. The difference in volume of the total prostate has not been statistically significant whereas the difference in the volume of the transitional zone between the 3 age groups has been significant. Conclusions The volume of total prostate and that of the transitional zone increases with age. The speed of hyperplasia of the transitional zone has been faster than that of the whole prostate.The index of the transitional zone indicates the difference of the whole prostate and the transitional zone in hyperplasia.

OBJECTIVE:To analyze and compare the congruity between Maria and DDW-J standard and Roussel uclaf causali-ty assessment method(RUCAM)for diagnosing drug-induced liver injury(DILI),and evaluate its application. METHODS:In ret-rospective analysis,the clinical data of 122 patients with DILI with RUCAM ≥3 scores was quantitatively scored by Maria and DDW-J standard,χ2 test was conducted for statistical analysis. RESULTS:Among the 122 cases,120 cases(98.4%)were classi-fied as“likely and possible”by DDW-J standard,which was significantly higher than the 58 cases(47.5%)that classified as“pos-sible”by Maria standard,with statistical significance;and compared with Maria standard,DDW-J standard was more closer to RU-CAM scoring results. CONCLUSIONS:DDW-J standard is superior to Maria standard,and close to RUCAM scoring results for DI-LI;RUCAM is still the DILI diagnostic evaluation system with high accuracy and operability.

Objective To construct a cDNA subtractive library of genes transactivated by c-terminally truncated middle surface protein of hepatitis B virus(MHBs t) with suppression subtractive hybridization technique for cloning genes associated with transactivation. Methods The mRNA was isolated from HepG2 cells transfected with pcDNA3.1(-)-Mt167 and pcDNA3.1(-) empty vectors, respectively, then cDNA was synthesized. After restriction enzyme Rsa I digestion, small-size cDNAs were obtained. Then tester cDNA was divided into two groups and ligated to the specific adaptor 1 and adaptor 2, respectively. After tester cDNA was hybridized with driver cDNA twice and underwent two times of nested PCR and then was subcloned into T/A plasmid vectors to set up the subtractive library. Amplification of the library was carried out with E. coli strain JM109. The cDNA was sequenced and analyzed in GenBank with Blast search after PCR. Results The subtractive library of genes transactivated by MHBs t was constructed successfully. The amplified library contained 94 positive clones. Colony PCR showed that these clones contained 200-800bp inserts. Sequence analysis was performed in 50 clones,and the full length sequences were obtained with bioinformatics method. 23 coding sequences were obtained in total, which consisted of 19 known and 4 unknown ones.Conclusions The obtained sequences may be target genes transactivated by MHBs t, among which some genes coding proteins may involve in cell cycle regulation, immune response and tumour genesis.
