OBJECTIVETo compare the clinical, pathological, laboratory test and follow-up data between familial and sporadic patients with distal myopathy with rimmed vacuoles (DMRV) and discuss the characteristics of this disorder in Chinese population.
METHODSThe clinical and pathological features, laboratory data and follow-up results of 33 sporadic and 4 familial cases of pathologically confirmed DMRV were summarized and compared retrospectively.
RESULTSThe patients age, onset age, or disease duration showed no significant difference between sporadic and familial cases; the onset pattern and affected muscle groups were also similar, but the sporadic cases showed more frequent dysmorphic features than the familial cases. The patients showed mild to moderate elevation of the muscle enzymes by one to three folds, and the familial patients had more significant elevation than the sporadic ones. No correlation was found between the disease duration and the level of muscle enzymes. The pathological findings were similar between the cases, and Gomori staining showed rimmed vacuoles and inclusion bodies without inflammatory cell infiltration. Follow-up results of 29 cases showed no significant difference between the two groups. The disease was slowly progressive and severely affected the quality of life of the patients, but did not produce obvious effect on the life expectancy.
CONCLUSIONThe clinical, pathological and laboratory data of Chinese DMRV patients are basically similar to those of Japanese cases. Sporadic cases tend to show more dysmorphic features than the familial ones, and occasional sporadic cases have early disease onset in early childhood.

OBJECTIVETo explore the effect of compound qizhu granule (CQG) on cellular immunity of chronic hepatitis B (CHB) patients.
METHODSTotally 103 CHB patients treated with lamivudin (LAM) for 6 months, who had partial virological response (HBeAg positive) were randomly assigned to two groups, 50 in the treatment group and 53 in the control group. All patients took LAM 100 mg (once a day) plus ADV 10 mg (once a day). Patients in the treatment group additionally took CQG, one dose per day. After one-year treatment hepatitis B virus (HBV) DNA negative rates, HBeAg seroconversion, levels of HBV specific cytotoxic T lymphocyte (CTL), non-specific CTL and natural killing (NK) cells were compared between the two groups.
RESULTSAfter 1-year treatment, HBV DNA negative rate of the treatment group was 88: 0% in 44 cases, slightly higher than that of the control group (41 cases, 77.4%), but with no statistical difference (P >0.05). HBeAg seroconversion of the treatment group was 32.0% in 16 cases, higher than that of the control group (8 cases, 15.1%), with statistical difference (P <0.05). Levels of HBV specific CTL (0.79%±0. 07%), non-specific CTL (19.4%±1.8%) and NK cells (14. 1%± 1.5%) of the treatment group were higher than those of the control group (0.58% ± 0.08%, 17.5% ± 1.7%, and 11.1%±1.5%, respectively; allP <0.01).
CONCLUSIONTreating CHB patients with partial virological response by ADV plus CQG could improve specific and non-specific cellular immunity, thereby elevating HBeAg seroconversion rate.

OBJECTIVEThis study aimed to explore the impact of specimen collection and storage consumable products on trace element quantitative analysis.
METHODSDevices and consumable products of different brands used in specimen collection or storage were selected and treated separately as below:urine collection and storage tubes (Brand A, B, C and D, 2 samples for each brand) were treated with 1% of HNO(3) volume fraction for 2 - 4 h; blood taking device (Brand O, P and Q, 3 samples for each brand) were used for ultra-pure water samples collecting as simulation of blood sampling;dust sampling filters (Brand X, Y and Z, 2 samples for each brand) were cold digested by nitric acid for 12 h, followed by microwave digestion. Then cadmium, cobalt, chromium, copper, iron, manganese, molybdenum, nickel, lead, selenium, stannum, titanium, vanadium and zinc concentrations in the solutions obtained during the course of collect or storage were quantified by inductively coupled plasma mass spectrometer.
RESULTSFor the urine collection and storage consumable products, background values of elements were described as mean of parellel samples. The consentration of 14 quantified elements were relatively low for 5 ml cryogenic vials (brand B) with background values range of 0.001 - 0.350 ng/ml. The background values of copper of 50 ml centrifuge tubes (brand A), chromium of 5 ml cryogenic vials (brand C) and zinc of 1.5 ml centrifuge tubes (brand D) were relatively high, which were 1.900, 1.095 and 1.368 ng/ml, respectively. Background values of elements in blood sampling devices were described as x(-) ± s. Background values of chromium for brand O, P and Q were (0.120 ± 0.017), (0.337 ± 0.093) and (0.360 ± 0.035) ng/ml; for copper were (0.050 ± 0.001), (0.017 ± 0.012) and (0.103 ± 0.015) ng/ml; for lead were (0.057 ± 0.072), (0.183 ± 0.118) and (0.347 ± 0.006) ng/ml; for titanium were (7.883 ± 0.145), (8.863 ± 0.190) and (8.613 ± 0.274) ng/ml; zinc were (2.240 ± 0.573), (42.140 ± 22.756) and (8.850 ± 3.670) ng/ml. There were statistically differences of background values for chromium, copper, lead, titanium and zinc among the above three brands of blood sampling devices (all P values < 0.05). For air sampling filters, background values of elements were described as mean of parellel samples. Background values of chromium and nickel of sampling filters (brand X) were lowest, which were 17.000 and 15.400 ng per piece, respectively; while background values for other elements were relatively high, the quantification of cadmium, cobalt, copper, iron, manganese, molybdenum, lead, selenium, stannum, titanium, vanadium and zinc were 0.250, 0.550, 48.500, 690.000, 25.500, 0.900, 6.500, 10.550, 7.950, 10.500, 0.850, 370.000 ng per piece, respectively. Background values of chromium and nickel of sampling filters (brand Z) were highest, which were 171.000 and 29.850 ng per piece.
CONCLUSIONBackground values of trace elements varied among products of different brands, and the most noticable differences were found in chromium, manganese, nickel, lead, stannum and zinc.

BACKGROUNDTo explore the cut-off period of subclassification and pathological features of severe hepatitis (SH).
METHODSBased on combined clinical and pathological analyses, the complete clinical and biopsy or autopsy liver tissues data from 196 cases of patients with severe hepatitis were investigated. Meanwhile, proliferative hepatocytes, cholangioepithelia and collagens were identified by a panel of monoclonal antibodies such as those against albumin, cytokeratin 18,19 and collagen I, III with immunohistochemical method.
RESULTSThe clinical and pathological analyses indicated the cut-off periods of acute, subacute and chronic SH (ASH,SSH and CSH) were (13.4+/-7.2) d, (77.4+/-69.3) d and (80.5+/-63.2) d, respectively. Among all SH cases, one case of ASH patient presented clinical manifestation and pathological changes of ASH for 21 days, however, one patient with SSH was demonstrated 12 day course by histological examination. The time of cut-off period between ASH and SSH in child cases was shorter than that in adult cases. Histologically, ASH liver tissues showed massive and/or submassive necrosis caused by one attack, with congestive sinusoid frameworks and proliferative cholangioepithelium-like hepatocytes, while SSH liver tissues presented combined fresh and old submassive or massive necrosis caused by multiple attacks, accompanied by obviously proliferative bile ducts and sinusoid framework collapse.However, the pathological changes of CSH showed ASH- or SSH-like lesions on the background of chronic liver injury.
CONCLUSIONOur data indicated that the cut-off period between ASH and SSH is in accordance with the Scheme of Viral Hepatitis Prevention and Therapy, China, published in 2000, but excluded a part of child SH cases. In our study, the authors found a few pathological features in ASH and SSH.

Lung is the largest organ of the respiratory system. During hypoxia, pulmonary cells undergo rapid damage changes and activate the self-rescue pathways, thus leading to complex biomacromolecule modification. Death from mechanical asphyxia refers to death due to acute respiratory disorder caused by mechanical violence. Because of the absence of characteristic signs in corpse, the accurate identification of mechanical asphyxia has always been the difficulty in forensic pathology. This paper reviews the biomacromolecule changes under the pulmonary hypoxia condition and discusses the possibility of application of these changes to accurate identification of death from mechanical asphyxia, aiming to provide new ideas for related research.
