ABSTRACT
Objective To recapitulate the clinical traits of conjunctiva-corneal carcinoma in situ with microinvasion,and explore the early diagnosis and precise therapeutic methods.Methods The clinical features,diagnosis,surgical methods and follow-up results of a hospitalized patient with keratoconjunctival in situ carcinoma with microinvasion were retrospectively analyzed and related literature was consulted.Results Surgical resection of the tumor and 2 mm marginal tissue outside the edge of the tumor was performed.Fresh corneal lamellar grafts were used to treat the disease.After 2 years of follow-up,the operation was effective and no recurrence was found.Conclusion Early diagnosis plays an important role in improving the prognosis of keratoconjunctival carcinoma in situ with microinvasion and preventing recurrence.For patients with keratoconjunctival carcinoma in situ acompanied with microinvasion,we have to expand the surgical resection of the tumor (≥2 mm at the edge of the tumor),and follow-up at regular intervals,if necessary,supplemented with chemotherapy or anti-metabolic treatment.
ABSTRACT
OBJECTIVE:To observe the outcomes of umbilical cord blood mesenchymal stem call transplantation for treating neural function of multiple system atrophy (MSA) patients.METHODS:A total of 20 MSA patients were selected at the Beijing Wu Stem Cells Medical Center from January to October 2008.All patients received treatment of vessel distention,anti-free radical,trophic nerve and call membrane stabilization,as well as umbilical cord blood mesenchymal stem call transplantation via intrathecal injection.Patients at left-lateral position,and body bent at hips,knees and necks.Acupuncture was conducted at the space of lumbar vertebra 3 and 4.Following local anesthesia,No.9 needle was directly pricked into the subarachnoid cavity.2 mg dexamethasone was slowly infused,and 5 mL (5×106 stem cells) umbilical cord blood mesenchymal stern call injection was obtained and slowly infused into the subarachnoid cavity within 10 minutes,once per week,four times as a course,totally one course.We adopted Unified Multiple System Atrophy Rating Scale (UMSARS) to evaluate those MSA patients.The higher score represented a severe pathogenetic condition.RESULTS:Compared with pretransplantation,the UMSARS score was significantly decreased in 20 patients 4 weeks follwing transplantation (P ＜ 0.01).After the treatment,patient's clinical symptoms such as slow movement,balance disturbance,orthostatic hypotension,urinary and bowel disorders had full obvious improvement.Graft versus host disease was not found.CONCLUSION:It is indicated that mesenchymal stem call transplantation is effective,can partly improve MSA patients' clinical symptoms,and improve patients' life quality.
ABSTRACT
BACKGROUND:Qingre Huoxue Xiaozhong composition Ⅰ and Ⅱ made by ourselves are effective in treating bone fracture complicated by soft tissue injury.However,its mechanism is still unclear.OBJECTIVE:To observe the effect of Qingre Huoxue Xiaozhong composition on the levels of intedeukin 1β(IL-1β) and interleukin 6(IL-6) in serum of patients with closed bone injury-induced soft tissue injury.DESIGN:Randomized controlled observation.SETTING:Wards of the Department of Traditional Chinese Medicine,the 401 Hospital of Chinese PLA.PARTICIPANTS: Eighty-eight inpatients with bone fracture at early and moderate stages accompanied by soft tissue injury were chosen as volunteers to be studied in the Department of Traditional Chinese Medicine,the 401 Hospital of Chinese PLA between February 2000 and February 2002.The involved inpatients were assigned into 2 groups according to the table of random digit:Oingre Huoxue Xiaozhong composition Ⅰ + Ⅱ group (n=45) and Qingre Huoxue Xiaozhong composition Ⅱ group (n=43).Oingre Huoxue Xiaozhong composition Ⅰ was for internal administration,and Qingre Huoxue Xiaozhong composition Ⅱ was for external fumigation.METHODS:①Treatment of bone injury:Both caltrate D pellets and pills for strengthening bone joints were used in two groups.②Treatment of soft tissue injury: In the Qingre Huoxue Xiaozhong composition Ⅰ+ Ⅱ group,Qingre Huoxue Xiaozhong composition Ⅰ was decocted.Each decoction was 450 mL,and was packed into 3 pouches, 150 mL/pouch,three times a day;Qingre Huoxue Xiaozhong composition Ⅱ was decocted.Each decoction was 600 mL,and was packedinto 4 Douches,150 mL/pouch.Four pouches of Qingre Huoxue Xiaozhong composition Ⅱ was diluted by 2 000 mL water,then heated and used for fume-washing, twice a day, 20 to 30 minutes once. Four pouches could be used for fume-washing for 2 days successively. In the Oingre Huoxue Xiaozhong compositionⅡgroup, only Oingre Huoxue Xiaozhong composition Ⅱ was used to fume-wash the lesioned region.The concrete method was the same as that in the Qingre Huoxue Xiaozhong composition Ⅰ+Ⅱ group.In each group, ten days were set as one course of treatment,and totally, there are 2 courses of treatment.IL-1β and IL-6 levels in serum of patients were detected by with ELISA kit before.one and two courses after treatment, and compared separately.MAIN OUTCOME MEASURES: Levels of IL-1β and IL-6 in serum of patients in two groups before, one and two courses after treatment.RESULTS: In the eingre Huoxue Xiaozhong composition Ⅰ+Ⅱ group,the level of IL-1β and IL-6 was respectively significantly lower after 2 courses of treatment as compared with the previous one and one course after treatment (P＜0.05-0.01), also at the same time point in compared with the Qingre Huoxue Xiaozhong composition Ⅱ group (P＜0.05).In addition, in the Oingre Huoxue Xiaozhong composition Ⅰ+Ⅱ group,the level of IL-1β and IL-6 was respectively significantly decreased after one course of treatment as compared with before treatment (P＜0.05). In the Oingre Huoxue Xiaozhong composition Ⅱ group,after 2 courses of treatment,the level of IL-1β was significantly decreased as compared with before treatment, and the level of IL-β was also significantly decreased as compared with before treatment and after one course of treatment (P＜0.05).CONCLUSION: Qingre Huoxue Xiaozhong composition Ⅰ+Ⅱ can be used to treat bone fracture accompanied by soft tissue injury by inhibiting the levels of IL-1β and IL-6. The effect of the combination of Oingre Huoxue Xiaozhong composition Ⅰ and Ⅱ is superior to that of each alone.
ABSTRACT
Objective To identify and quantitate the conjunctival aerobic bacterial flora from healthy people of 3 age groups in Chongqing city.Methods Samples taken with moist swabs from the lower fornix of both eyes of 33 children(9.85?0.57 years old),31 youths(21.23?0.88 years old)and 30 elders(72.97?4.94 years old)were given bacterial cultures.Positive ones were identified and colony forming units(CFUs)were counted.Bacterial quantity was expressed as the number of CFUs divided by the weight of each sample measured before and after collection.Results The elders showed a higher isolation frequency(93.33%)than children(45.45%)and youths(50.00%)which had statistically difference(P
ABSTRACT
ObJective To measure the level of MDA and SOD in cerebrospinal fluid from patients with cysticercosis indifferent stages and to investigate their effects on this dieases. Methods Forty-nine patients with a single cysticercus incerebral parenchyma and twenty normal controls parlticipated in the study. According to the magnetic resonance imaging(MRI) results, patients were divided into four stages. The level of MDA,SOD in CSF were tested. The data were analyzedwith the software of SPSS. Results The amount of SOD was significantly decreased in all stages except the fourth stage,while the level of MDA was increased in all the stages,and reached its peak in the second stage. There was a negative cor-relation between SOD and MDA. Conclusion The data suggested oxygen free radicals may be a main mechanism of para-site killing.
ABSTRACT
Thirty-four patients with severe chronic active viral hepatitis were divided into 2 groups. One group was treated with prostaglandin E_1, (PGE_1,) and supportive therapy, and the other was treated with supportive therapy only and served as the control. The effects of PGE_1, on plasma lipid peroxides (LPO) level, plasma prostacyclin (PGI_2) and thromboxane A_2 (TXA_2), plasma cyclic nucleotide and liver function were determined to investigate the mechanism of PGE1. It was found that PGE_1 could achieve the following effects.1. Reduction of plasma LPO level (P
ABSTRACT
Effect of cell-free preparation of human fetal liver (cytosol and its dialysa-te) , human fetal muscle cytosol(FMC) and human adult liver cytosol (ALC) on survival rate of rats with acute hepatic failure induced by D-galactosamine was studied. The components of the 4 preparations were analysed preliminarily. Results: 1 ,fetal liver cytosol(FLC) could increase the survival rate(SR) of rats with hepatic failure(HF) comparing with normal saline(P0.05) . The SR of rats with HF was reduced by ALC markedly) 2,IgG,IgA,IgM and C3 could not be detected in FLC, but a few kinds of hormones, trace elements, glucose and lipids, and biological large molecule substances (BLMS) such as nucleic acids and proteins were found. As to free amino acid,content of branch chain amino acids in FLC was significantly higher than that in ALC, but the content of aromatic amino acids and ammonia was markedly lower than that in ALC.The components in FLD were almost the same as in FLC except BLMS.These data suggest that the soluble BLMS in FLC may play a key role in treating HF. ALC could reduce SR and contained a large amount of poisonous substances such as aromatic amino acids and ammonia.
ABSTRACT
The effects of different vitamin E(VE) containing diets on lipid peroxi-dation and the degree of liver damage in rats were observed in the model of liver necrosis induced by galactosamine(D-GAL).The results were as follows: After 8 weeks, the basic levels of VE in plasma and liver tissue of the group fed VE-supplemented diet were significantly higher than that of the group fed normal VE diet, in the company with a significant lower basic plasma MDA level. At each time interval after D-GAL injection, the plasma and liver VE levels were found higher in the VE-supplemented group, and the content of GSH as well as the activities of SOD, GSH-Px, HPT were maintained satisfactorily while the MDA content and OCT, m-AST activities were very significantly lowered and the pathological changes of the liver were not so severe as compared with that in the normal VE diet group. It was noteworthy that the changes of almost all the parameters metioned above in the group fed VE-deficient diet went to an opposite direction to the VE-supplemented group. The results indicated that the VE-supplemented diet has a good liver protective effect, which may be established on the increased VE content and suppressed lipid peroxidation in the liver. VE-deficient diet could sharply reduce the VE content in the body and significantly intensify the susceptibility of liver to the harmful agents.
