Objective To observe the clinical efficacy of bamboo-circled salt-partitioned moxibustion in treating arthritis of temporomandibular joint.Method Eighty patients were randomized into two groups. Forty cases in the bamboo-circled salt-partitioned moxibustion group received bamboo-circled salt-partitioned moxibustion at temporomandibular joint; forty cases in the warm needling group were intervened by selecting Xiaguan (ST7), Ashi point, etc. at the affected side. For the two groups, 3-day treatment was taken as a treatment course, and the therapeutic efficacy was analyzed after 2 treatment courses. The improvements in pain and mouth opening were observed before and after the treatment, and the treatment efficacy was evaluated by a 1-month follow-up study.Result The bamboo-circled salt-partitioned moxibustion group was superior to the warm needling group in comparing the real-time analgesic effect (P<0.05) and in the improvement of mouth opening (P<0.05); the comprehensive markedly effective rate was respectively 67.5% and 45.0% in the bamboo-circled salt-partitioned moxibustion group and warm needling group, and the between-group difference was statistically significant (P<0.05), indicating that bamboo-circled salt-partitioned moxibustion is better than warm needling in treating arthritis of temporomandibular joint; the follow-up study revealed satisfactory therapeutic efficacies in both groups: the effective rate was 92.5% in the bamboo-circled salt-partitioned moxibustion group versus 87.5% in the warm needling group, and the difference was statistically insignificant (P>0.05).Conclusion Bamboo-circled salt-partitioned moxibustion can produce a real-time analgesic effect and improve mouth opening; it's especially suitable to treat the patients who are afraid of needling, as it's significantly effective, safe, non-invasive,and easy-to-operate.

BACKGROUND:The important reason for failed back surgery syndrome is the postoperative epidural scar adhesions, therefore, exploring the methods of preventing postoperative lumbar epidural scar adhesions has always been a hot research in spine surgery field. OBJECTIVE:To investigate the effect of Shenshu point magnetic stimulation therapy on epidural scar adhesions in rat models of failed back surgery syndrome. METHODS:Sixty Sprague-Dawley rat models of failed back surgery syndrome were successfuly established using the method of laminectomy, and then divided into Shenshu magnetic therapy group and blank control group. Beginning from 1 week after modeling, rats in the Shenshu magnetic therapy group were subjected to bilateral Shenshu magnetic stimulation for 6 weeks, 5 days of treatment per week. Rats in the blank control group were not given any intervention. At 13 weeks after modeling, rats were harvested and the area ratio of epidural scars, range of adhesions and formation of colagen fibers were observed under light microscope. Fibroblasts were counted. Hydroxyproline content and transforming growth factor β1 expression in scar tissue were compared between these two groups.

Objective To investigate the clinical efficacy of heat-sensitive point moxibustion plus manipulative reduction in treating thoracic facet joint disorder. Method A single-blind randomized controlled trial was carried out. Eighty-two patients meeting the criteria were randomly allocated to an observation group of 42 cases and a control group of 40 cases. The observation group received heat-sensitive point moxibustion plus manipulative reduction and the control group, TDP plus manipulative reduction. Both groups were treated five times a week, five times as a course for a total of two courses (including the patients cured after less than two courses). The therapeutic effects were evaluated by using the McGill Pain Questionnaire the as the observation index, comparing pre-/post-treatment Pain Rating Index (PRI) scores, Visual Analogous Scale (VAS) scores and Present Pain Intensity (PPI) scores and referring to the Criteria of the Diagnosis of and the Therapeutic Effect on Syndromes in Traditional Chinese Medicine. Result After treatment, the PRI, VAS and PPI scores decreased significantly in both groups (P<0.01) and were lower in the observation group than in the control group (P<0.01). The cure rate was 57.1% (24/42) in the observation group, which was significantly higher than 27.5% in the control group (11/40,P<0.01). The total efficacy rate was 95.2% (40/42) in the observation group, which was significantly higher than 80.0% in the control group (32/40,P<0.01). Conclusion Heat-sensitive point moxibustion plus manipulative reduction has a very good therapeutic effect on thoracic facet joint disorder. The effect is significantly better than that in the control group.

A series of [1,3]dioxolo[4,5-f]isoindolone derivatives were designed, synthesized and evaluated as inhibitors of acetylcholinesterases (AChE). Furthermore, their effects on memory impairment of mice induced by scopolamine were investigated with step-through test. The results suggested that most of the target compounds exhibited potential inhibition on AChE with IC50 values at micromolar range. Compounds I1 (IC50 value of 0.086 μmol · L(-1)) and I2 (IC50 value of 0.080 μmol · L(-1)) showed the strongest AChE inhibitory activity, which are equipotent to donepezil (IC50 value of 0.094 μmol · L(-1)). Moreover, compounds I1-I4 could improve the memory impairment induced by scopolamine in mice.

Objective To explore the clinical diagnosis and management of focal nodular hyperplasia (FNH) of the liver. Methods Forty-two FNH cases treated in the past 9 years were studied retrospectively. The clinical and pathologic data were reviewed. Results Preoperative liver function test and AFP were normal. The preoperative radiography in FNH was usually not specific, with less than 50% cases were suggestive of FNH of the liver. Surgical resection resulted in a permanent cure with no significant postoperative complications. More than one year follow-up found recurrence in one case. Conclusion Clinical, laboratory and radiological findings when combined could help in establishing tentative diagnosis of FNH. Surgery is recommended in cases with equivocal diagnosis or in fear of hepatocellular carcinoma.

OBJECTIVETo investigate the chest X-ray manifestations of SARS cases.

METHODSA retrospective study was conducted among 52 clinically confirmed SARS patients from February 9 to May 10, 2003. Chest X-ray scanning was performed at a interval of 1 - 3 days according to the requirements. The manifestations and special features of SARS in X-ray were analyzed.

RESULTSSmall or large patchy shadows with intensive density in both lungs were observed in 31 cases, ground-glass like opacification in 16, small patchy shadows in one lung lobe or one lung segment in 18, nodular shadows in one lung segment in 1, and increased lung marking in lung interstitial tissues in 2. Rapidly changing consolidations revealed in chest X-ray images were found to be associated with SARS infections, and they were not affected by treatment with antibiotics.

CONCLUSIONChest X-ray provides a sensitive and specific method for the diagnosis and treatment of SARS, and those present with symptoms and signs should undergo chest X-ray scanning every 1 - 3 days.

Objective: To analyz the current situation of the diagnosis, treatment and prevention of methylmalonic acidemia, the phenotypes, biochemical features and genotypes of the patients in the mainland of China, were investigated. Methods: Tottally 1 003 patients of methylmalonic acidemia from 26 provinces and municipalities of the mainland of China were enrolled. The clinical data, biochemical features and gene mutations were studied. Blood aminoacids and acylcarnitines, urine organic acids, and plasma total homocysteine were determined for the biochemical diagnosis. Gene analyses were performed for the genetic study of 661 patients. The patients were treated with individual intervention and long-term follow up. Prenatal diagnoses were carried out for 165 fetuses of the families. Results: Among 1 003 patients (580 boys and 423 girls), 296 cases (29.5%) had isolated methylmalonic acidemia; 707 cases (70.5%) had combined homocysteinemia; 59 patients (5.9%) were detected by newborn screening; 944 patients (94.1%) had the onset at the ages from several minutes after birth to 25 years and diagnosed at 3 days to 25 years of age. The main clinical presentations were psychomotor retardation and metabolic crisis. Multi-organ damage, including hematological abnormalities, pulmonary hypertension, kidney damage, were found. MMACHC, MUT, MMAA, MMAB, HCFC1, SUCLG1, SUCLA2 mutations were found in 631 patients (96.6%) out of 661 patients who accepted gene analysis. MMACHC mutations were detected in 460 patients (94.7%) out of 486 cases of methylmalonic acidemia combined with homocysteinemia. MUT mutations were found in 158 (90.3%) out of 169 cases of isolated methylmalonic acidemia. The development of 59 patients detected by newborn screening were normal; 918 cases (97.2%) were diagnosed after onset accepted the treatment. Forty-five of them completely recovered with normal development. Twenty-six patients (2.7%) died; 873 (92.5%) patients had mild to severe psychomotor retardation. Methylmalonic acidemia were found in 35 out of 165 fetuses by metabolites assay of amniotic fluid and amniocytes gene analysis. Conclusion Combined methylmalonic acidemia and homocysteinemia is the common type of methylmalonic acidemia in the mainland of China. CblC defect due to MMACHC mutations is the most common type of methylmalonic acidemia combined with homocysteinemia. MUT gene mutations are frequent in the patients with isolated methylmalonic acidemia. Newborn screening is key for the early diagnosis and the better outcome. Combined diagnosis of biochemical assays and gene analysis are reliable for the prenatal diagnosis of methylmalonic acidemia.
