Hemorrhage of the basal ganglia is common in hypertensive patients, and most of the cases are spon- taneous unilateral hemorrhage. Traumatic basal ganglia hemorrhage is uncommon, while bilateral hemorrhage of the basal ganglia after trauma is an extremely rare entity. This report described a rare case of bilateral hemorrhage of the basal ganglia after head trauma. We also analyzed the mechanisms and reviewed relative literatures.

To determine the role of vagi in heart rate variability, conscious rabbits were employed and electrocardiogram was recorded under conditions of bilateral vagi intact, unilateral vagotomy, and bilateral vagotomy. The variability of RR intervals (RRI) was analyzed using power spectrum and approximate entropy (ApEn). The results showed that the values of high frequency power (HF) component, low frequency power (LF) component and ApEn in animals with bilateral vagi intact were the highest, but the LF/HF ratio was the lowest; unilateral vagotomy decreased ApEn, right vagotomy increased LF/HF ratio but left vagotomy did not; the LF/HF ratio increased while ApEn decreased significantly in animals with bilateral vagotomy. It is suggested that the variability of RRI is mainly regulated by the vagi and the role of right vagi is more important than that of the left. When measuring heart rate variability, the results obtained with conventional method are consistent with those with nonlinear method.

OBJECTIVETo analyze hepatotoxicity of Polygonum multiflorum and clinical character- istics of drug-induced liver injury (DILI) caused by Polygonum multiflorum and its preparations.

METHODSA retrospective study was performed in 158 patients treated at 302 Military Hospital between January 2009 and January 2014. All of them had used Polygonum multiflorum and its preparations before the onset of DILI, and their clinical characteristics and prognoses were analyzed.

RESULTSOf the 158 DILI patients who used Polygonum multiflorum or its preparations, 92 (58.2%) combined with Western medicine or Chinese herbal preparations without Polygonum multiflorum; 66 patients (41.8%) used Polygonum mult florum and its preparations alone. In 66 DILI patients induced by Polygonum multiflorum or its preparations alone, 51 cases (77.3%) were induced by Polygonum multiflorum compounds and 22.7% by single Po- lygonum multiflorum; 4 cases (6.1%) were caused by crude Polygonum multiflorum and 62 (93.9%) by processed Polygonum multiflorum and its preparations. Clinical injury patterns were hepatocellular 92.4% (61 cases), cholestatic 1.5% (1 case), and mixed 6.1% (4 cases). Pathological examination was per- formed by liver biopsy in 32 cases (48.15%), manifested as hepatocellular degeneration and necrosis, fibroplasia, Kupffer cells with pigment granule, and a large number of eosinophil infiltration, were ob- served. Four patients were developed into liver failure, 4 into cirrhosis, and 1 died.

CONCLUSIONPolygo- num multiflorum and its preparations could induce DILI, but clinical diagnosis of Polygonum multiflorum induced hepatotoxicity should be cautious.

OBJECTIVETo study whether the live attenuated AroA-auxotrophic mutant of Salmonella (S.) typhimurium (SL7207) could be used as DNA delivery vehicle to induce more efficient immune response by using the eukaryotic expression plasmid pCMV-beta as report gene.

METHODSMurine peritoneal macrophages were infected with SL7207(pCMV-beta) in vitro, then the expression of the beta-gal were detected by X-gal staining or RT-PCR. After mice were orally immunized with SL7207(pCMV-beta), the expression of beta-gal in the lymphoid tissue were tested by RT-PCR, humoral responses were tested by ELISA, splenic lymphocyte proliferation were tested by 3H-TdR incorporation and cytotoxic T lymphocyte reaction were tested by JAM test.

RESULTSThe results indicated that the plasmid pCMV-beta could be delivered by SL7207 into the nucleus of the murine macrophages efficiently and expressed well in vitro; after mice received oral immunizations with attenuated S.typhimurium SL7207 harboring plasmid pCMV-beta mice, the expression of beta-gal could be detected in the spleen, mesenteric lymph nodes and Peyers patches of the mice. Furthermore, the experiments demonstrated that specific humoral immune responses and cell-mediated immune responses were successfully induced in these immunized mice. Compared with the naked DNA vaccination, SL7207 (pCMV-beta) oral immunization were more efficient in inducing cellular immune responses.

CONCLUSIONSAttenuated Salmonella typhimurium SL7207 could be used as DNA delivery vehicle for oral immunization, which have the ability to deliver the antigen-encoding DNA specifically to APC directly for inducing the specific immune response being dominant with cellular immune response.

OBJECTIVETo describe the incidence and mortality rates of esophageal cancer from 1974-2002 in Cixian county of Hebei province. Basic information on comparative geographical, epidemiological, and clinical research was collected.

METHODSIn early 1970s, cancer registry system in Cixian was established, collecting information on all the esophageal cancer cases in Cixian. Data was checked manually, then computerized, coded and analyzed using the software--SPSS 11.5.

RESULTSFrom 1974 to 2002, there were 18 471 esophageal cancer cases in Cixian, with 11 068 males and 7403 females, respectively. The age standardized incidence rate (ASR) for males was 208.77 per 100,000, while 120.47 per 100,000 for females. The trend of incidence rate of esophageal cancer had decreased during the 29 years from 1974 to 2002 (trend chi(2) = 19.94, P < 0.001). From 25 years of age onward, the incidence rates of the lower age groups declined with the increase of age. As for geographic distribution, the incidence rate in mountainous areas and hilly areas showed a significant declining trend in mountainous areas, chi(2) = 195.00, P < 0.001; hilly areas, chi(2) = 46.08, P < 0.001. The esophageal cancer incidence in plain areas remained steady, but had a slight increase in recent years. From 1969 to 2002, there were 18,736 cases died of esophageal cancer with 11 598 males and 7138 females. The ASR for male was 127.17 per 100,000 and 101.57 per 100,000 for female. Compared with the year 1969, the mortality rate of esophageal cancer in 2002 had a 37.96% decline. The proportion of esophageal cancer among malignant tumors in different decades decreased significantly.

CONCLUSIONThe trend of the incidence rate of esophageal cancer had been decreasing for the last 29 years. The incidence rate in mountainous areas and hilly areas showed a declining trend while in the plain areas it remained steady but having slight increase in the recent years. The mortality rate of esophageal cancer had a significant decrease from 1969 to 2002.

BACKGROUNDSevere acute respiratory syndrome (SARS) is a disease with a mortality of 9.56%. Although SARS is etiologically linked to a new coronavirus (SARS-CoV) and functional cell receptor has been identified, the pathogenesis of the virus infection is largely unclear.

METHODSThe clinical specimens were processed and analyzed using an indirect enzyme-linked immunosorbent assay (ELISA) in-house. Further investigations of target antigen included reviews of phage display technique, rapid amplification of cDNA ends (RACE) technique, protein expression and purification, Western blotting validation, serological and immunohistochemical staining in postmortem tissue.

RESULTSA type of medium or low titer anti-lung tissue antibodies were found in the sera of SARS patients at the early stage of the disease. Human long interspersed nuclear element 1 (LINE1) gene endonuclease (EN) domain protein was one of the target autoantigens and it was aberrantly expressed in the lung tissue of SARS patients. Anti-EN antibody was positive in the sera of 40.9% of SARS patients.

CONCLUSIONSHuman LINE1 endonuclease domain was identified as a putative target of SARS-associated autoantibodies, which were presented in the serum of SARS patients and may be involved in the pathogenesis of SARS.
