Tuberculous meningitis is an important global medical problem which gives rise to high morbidity and
mortality. It is the most severe form of extrapulmonary Mycobacterium tuberculosis. Comprehensive
prevention effort, prompt diagnosis and rational treatment are all keys to improving treatment outcomes;
yet many unsolved problems remain. On the other hand, the new problems, such as HIV co-infection and
drug-resistance are posing important challenges. This review outlines the epidemiology, pathogenesis,
diagnosis, management and prognosis of tuberculous meningitis. We mainly focus on research carried
out in the recent decades, giving special attention to the work done among the Asian populations

Objective To evaluate the effect of early continuous renal replacement therapy(CRRT)on patients with acute kidney injury(AKI)induced by severe sepsis. Methods A prospective study was conducted. 160 patients with AKI induced by severe sepsis admitted to intensive care unit(ICU)of Qingyuan People's Hospital between October 2009 and June 2013 were enrolled. According to the starting time of CRRT,the patients were randomly divided into two groups:an earl y treatment group and a regular treatment group(each,80 cases). All patients were treated in accordance with the principle of the cluster of severe sepsis. In early treatment group,the patents began to receive CRRT when the amount of urine output was<0.5 mL?kg-1?h-1 and had taken continuous conventional treatment over 6 hours,but the curative effect was not ideal. In the regular treatment group,the patients began to apply CRRT when the amount of urine output was<0.5 mL?kg-1?h-1 and had taken continuous conventional treatment persistently over 24 hours or difficultly corrected acidosis or heart failure developed. The changes in urine output,creatinine,saturation of blood oxygen,and albumin,and 28-day survival rate,length of ICU stay,time of organ support were measured and compared between the two groups to evaluate the therapeutic significance of the early CRRT. Results The mean length of ICU stay(day:6.5±1.7 vs. 8.2±1.6),length of organ support(day:5.3±1.8 vs. 6.0±1.4),the recovery time of urine amount(day:3.4±0.9 vs. 4.8±0.5)in early treatment group were significantly shorter than those in regular treatment group(all P<0.01);recovery ratio of urine in 1 week in early treatment group was significantly higher than that in regular treatment group(46.2%vs. 28.8%,P<0.05). The creatinine recovery ratio in 1 week in early treatment group was lower than that in regular treatment group(55.0%vs 78.8%),but there was no statistically significant difference(P>0.05). Early treatment group and regular treatment groups of creatinine recovery time were similar(day:5.1±1.3 vs. 5.2±1.2). 28-day survival rate in early treatment group was higher than that in regular treatment group(41.2%vs. 35.0%),but there was no statistically significant difference(P>0.05). Conclusion It is found that there is no evidence to suggest that early CRRT may improve the prognosis of the patients with AKI induced by severe sepsis,but it may be in favor of shortening the time of urine recovery,length of stay in ICU,length of organ support and length of dialysis.

Objective To study the similarities and differences on in vitro replication and expression of hepatitis C virus (HCV) between human fetal hepatocytes (HFH) and 7721 cell line. Methods Human fetal hepatocytes and a hepatoma cell line 7721 were incubated with a serum from hepatitis C patient. After incubation, the presence of HCV RNA, the expression of HCV NS3 antigens in cells and/or supernatant were examined by RT-PCR, in situ hybridization and immunohistochemistry, respectively. Results It was found that: ①The intracellular HCV RNA was first detected on d 2~3 post-incubation and then could be intermittently detected in cells and/or supernatant subsequently (HCV RNA could be detected in 7721 cells during a period of at least 66 days. In HFH, HCV RNA could be detected up to 25 days after incubation); ②HCV-NS3 antigen could be expressed in infected cells; ③Minus-strand RNA of HCV was mainly located within cytoplasm by in situ hybridization. Conclusion The results suggest that both the fetal hpatocytes and the hepatoma cell line 7721 are susceptible to HCV, and especially 7721 cell line can stably support HCV replication in vitro and may be used as the target cell for long-term cultures of HCV.

BACKGROUND: Distally based flap pedicled with the distal nutritional vessels in forearm is especially suitable for reconstructing the tissue defects in the distal end of hands, while high rotation point cannot satisfy the requirements of reconstructing the distal injuries or defects in hands, and severer lesion may even be caused in the donor site.OBJECTIVE: To study the anatomic proceeding of artery perforators in distal radial margin of forearms, so as to provide anatomic basis for the design of distally based compound flap pedicled with the nutrient vessel of cephalic vein in distal radial margin of forearms.DESIGN: Single sample experiment.SETTING: Center for Clinical Anatomy of the Department of Orthopedics,Fuzhou General Hospital of Chinese PLA of Nanjing Military Area Command.MATERIALS: The experiment was conducted in the Laboratory of Center for Clinical Anatomy of Department of Orthopedics, Fuzhou General Hospital of Chinese PLA of Nanjing Military Area Command between August and December 2004. The upper extremities of 30 cadavers injected with a mixture of red gelatin into the artery (provided by the Center for Clinical Anatomy of Department of Orthopedics, Fuzhou General Hospital of Chinese PLA of Nanjing Military Area Command) were adopted.METHODS: The vascular external diameter and distance were measured with sliding caliper and ruler with radial styloid process as the marker.MAIN OUTCOME MEASURES: ① The perforator artery in distal radial margin of forearms. ② The nutrient vessels of cephalic vein. ③ The relationship of blood supply between the nutrient vessels and vicinal bone and skin as well as the lateral antebrachial cutaneous nerve. ④ The superficial and deep communicating branches of cephalic vein.RESULTS: The perforator artery in distal radial margin of forearms derived from: 6-11 cutaneous branches of radial artery with external diameter of (0.7±0.3) mm; 2-6 cutaneous branches of superficial palma with the external diameter of (0.5±0.3) mm; 1-2 recurrent cutaneous branches of the styloid process of radius with the external diameter of (0.5±0.1) mm; 1-2 cutaneous branches of snuff tobacco with the external diameter of (0.6±0.2) mm. At 8.0-15.0 cm above radius styloid process there were 1-3 intermuscular cutaneous branches of radial artery with an initial external diameter of (1.1±0.2) mm, distributing in the exposureregion and corresponding skin of middle and inferior segments in radius. The above-mentioned perforator arteries all developed into cutaneous branch, fascia branch, periosteum branch, cephalic vein and nutrient vessel branch of distal cutaneous nerve,and constituted the vascular chain, the by-pass of cephalic vein, vascular chain of cutaneous nerve stem as well as superficial, deep fascias and periosteal vascular net.CONCLUSION: The perforator artery in distal radial margin of forearms is the source of nutrient vessels in cephalic vein, while the nutrient vessels share an isogeny with the nutrient vessels derived from vicinal bone, skin and lateral antebrachial cutaneous nerve, which provide an anatomic basis for designing the distally based compound flap pedicled with the nutrient vessels of cephalic vein. The rotation point of compound flap pedicled with the recurrent branch of radius styloid process (or branch of snuff tobacco) can reach the surface of rotation joint, which can be adopted in the transposition and reconstruction of distal tissue defects in hands.

Objective To discuss the clinical efficacy of compound gastritis mixture (CGM) in treating precancerous lesions of gastric carcinoma (PLGC).Methods Totally 85 PLGC patients were randomly divided into treatment group and control group. The treatment group took CGM and the control group took Vitacoenzyme tablets. One therapeutic course was three months, and the treatment lasted for two courses. The clinical symptoms, electronic gastroscopy presentation, and pathological tissues before and after treatment were observed, the clinical efficacy was evaluated.Results There was statistical significance in TCM syndrome between the two groups (P<0.05), and the effective rate in the treatment group was more obvious than that in the control group (P<0.01). The symptoms of the two groups were significantly improved (P<0.05,P<0.01), but the improvements of the main symptoms in the treatment group were superior to those in the control group (P<0.05,P<0.01). The total effective rate of electronic gastroscopy presentation was 80.0% (36/45) in the treatment group, which was better than that of the control group (P<0.05). Pathological curative effects of chronic atrophic gastritis, intestinal metaplasia, and dysplasia in the treatment group were also better than those in the control group (P<0.05).Conclusion CGM has definite clinical efficacy in treating PLGC.
