OBJECTIVETo compare the efficacy differences between dog-days medicinal vesiculation and regular-day medicinal vesiculation for perennial allergic rhinitis (PAR), and observe their effects on serum immune globulin E (IgE) and interleukin-4 (IL-4).

METHODSSeventy-two patients were randomly divided into a dog-days moxibustion group (34 cases) and a regular-day moxibustion group (38 cases). In the dog-days moxibustion group, medicinal vesiculation was applied on the 1st dog-day, 2nd dog-day and last dog-day in summer by lunar calendar, 3 treatments per dog-day for totally 9 times. In the regular-day moxibustion group, the moxibustion was given on the regular day for continuous 9 times. The symptom score, rhinoconjunctivitis quality of life questionnaire (RQLQ) and the level of IgE and IL-4 were compared before and after treatment in two groups; the short-term and two-year efficacy evaluation were performed too.

RESULTSThe short-term total effective rate was 88.2% (30/34) in the dog-days moxibustion group, which was not significantly different to 86.8% (33/38) in the regular-day moxibustion group (P>0.05). The long-term total effective rate was 97.1% (33/34) in the dog-days moxibustion group, which was significantly superior to 81.6% (31/38) in the regular-day moxibustion group (P<0.05). After treatment, the serum IgE, IL-4 and RQLQ were significantly reduced (all P<0.01), but the difference between two groups was not significant (all P>0.05).

CONCLUSIONMedicinal moxibustion could be taken as a regular treatment for PAR, which could be performed during the whole year, and dog-days moxibustion could be considered as an enhanced method for prevention and treatment of PAR.

The nitrite-reducing activity of aerobic denitrifying bacterial strain N6-1 was studied. It showed that the nitrite-reducing activity reached the highest at 30℃, 120 r/min, pH 8.5 and C/N ratio 12, using CH3COONa and NaNO2 as the sole carbon source and nitrogen source, respectively. When the initial NaNO2 concentration was 2 g/L, NO2--N was reduced completely after 20 hours cultivation with the reducing rate of 20.3 mg/L?h. There would be no effect on its nitrite-reducing activity in the present of 1.5% NaCl or 1% peptone. The cell concentration could reach 1.2?1011 CFU/mL after 24 hours cultivation in 10 L fermentor.

Segmental Spinal Instrumentation (S.S.I.) is considered to the effective operative procedure in unstable fracture and fracture-dislocation of the thoracolumbar spine, providing improved correction effect, high rate of fusion and immediate rigid fixation which obviates the need for postoperative immobilization. Retrospective study was carried out of 24 cases of fracture or fracture-dislication of the thoracolumbar spine, There were treated with Harrington rod instrumentation and sublaminar wiring (8 cases) and Luque rod instrumentatiom and sublaminar wiring (16 cases) in Soonchnhyang University, from January 1986 to June 1988. We have analyzed the results of treatment, which were as follows ; 1. Thoracolumbar junction (T12 Ll) was most commomly involved segment (63%) and falling from a height was most common cause of injuries. 2. The most common type by Denis classification was burst fracture (38%). 3. About improvement of neurologic status by injury site and type of instrumentation, thoracolumbar junction (38.5%) and lumbar spine (35%) were better prognosis than thoracic spine (8.75%). 4. In commparison with kyphotic deformity and displacement, Harrington rod (66.4%) was better than Luque rod (58.9%) in postoperative correction. Also in total correction, Harrington rod was better than Luque rod in spite of more or less large amount of loss of correction. words : Thoracolumbar spine, Unstable fracture-dislocation, Segmental spinal instrumentation (S.S.I.)

OBJECTIVETo observe the effects of Tongfu Decoction (TFD) on the gastric emptying of normal rats, thus exploring whether it could promote gastric emptying rapidly.

METHODSThirty Sprague-Dawley (SD) rats were randomly divided into 3 groups, i.e., the normal control group, the domperidone group, and the TFD group, 10 in each group. They were respectively administered with normal saline, the domperidone suspension, and TFD by gastrogavage. Thirty min later the gastric emptying of mice was detected by single photon emission computed tomography technology (SPECT) labeled with 99m Tc-DTPA, and the gastric half-emptying time and the gastric emptying rate were calculated.

RESULTSThe gastric half-emptying time was (19.0 +/-1.7) min in the normal control group, (12.9 +/- 3.4) min in the domperidone group, and (12.7 +/- 4.1) min in the TFD group. Compared with the normal control group, the gastric half-emptying time was significantly shortened in the domperidone group and the TFD group (P <0.05). The gastric emptying rate at 15 min was 41.1% +/- 5. 8% in the normal control group, 52.9% +/- 10.9% in the domperidone group, and 56.0% +/- 10.3% in the TFD group, while at 30 min it was 65.6% +/- 2.8%, 72.9% +/- 2.6%, and 72.4% +/- 4.9%, respectively. Compared with the normal control group, the gastric emptying rate at 15 min and 30 min both significantly increased in the domperidone group and the TFD group (P <0.05). There was no statistical difference in the gastric half-emptying time or the gastric emptying rate between the two groups (P >0.05).

CONCLUSIONTFD showed similar effects as domperidone in rapidly promoting gastric emptying, and could shorten the gastric half-emptying time in normal rats.

Objective To investigate the value of MR on diagnosis of intracranial primary lymphoma in immunocompetent patients.Methods The MR features of 28 cases with pathology proved intracranial primary lymphoma were analyzed retrospectively.Conventional MRI scans,enhanced MRI scan were observed.Immunohistochemical staining were done and the results were compared with the MR imaging signs. Results Twenty-eight cases were all B-cell type Non-Hodgkin's lymphoma,16 cases were single lesion (57%)and 12 cases were multiple lesions (43%).The tumors mainly located in the deep white matter,7 cases in callus corpus and grew crossing the midline supratentorial.The lesions presented mass or node (20/28),11 cases showed massive edema.On T1WI,lesions were mostly hypo-or iso-intense to gray matter.On T2WI,tumors showed iso-or hyper-intense.All lesions presented hyper-or iso-to hyper-intense on diffusion weighted imaging(DWI).Most lesions show marked mass-like or nodular-like contrast enhancement on MR imaging,8 cases presented"incision sign",5 cases showed"fist sign"and 7 cases showed"butterfly-like".Immunohistochemical staining showed that GFAP(-) was 78.6% (22/28),as well as CD20 (+)96.4% (27/28),CD79α(+)67.9% (19/28),CD10(+)10.7% (3/28),Bcl-6 (+)75% (21/28),Mum1 (+)89.3% (25/28).Ki-67 was greater than or equal to 50% (22/28).Among the 28 patients,25 cases (89.3%) showed an"activated non-germinal center B-cell(non-GCB)"in origin and 3 cases(10.7%)were considered as a"GCB"subset.Conclusion The imaging features of marked mass-kike or nodular-like on MRI enhancement scan and hyper-or iso-to hyper-intense on DWI are helpful in the diagnosis and the differential diagnosis of intracranial primary lymphoma.

Objective: To establish a scoring system for predicting the risk of side branch occlusion(SBO) in coronary bifurcation intervention based on visual estimation of quantitative coronary angiography (QCA). Methods: RESOLVE scoring system was developed from QCA. A total of 1545 patients with 1601 bifurcation lesions by RESOLVE study were enrolled. Based on RESOLVE scoring system, visual estimation was conducted to compare the consistency. According to SBO occurrence after main branch stent implantation, our research was divided into 2 groups: SBO group, which was defined by coronary angiography confirmed TIMI grade decreasing, n=114 patients with 118 lesions and Non-SBO group, n=1431 patients with 1483 lesions. Using RESOLVE scoring method as reference,V-RESOLVE scoring system was established, the discrimination, goodness-of-fit and V-RESOLVE score for the incidence of SBO were assessed;the diagnostic value for predicting the risk of SBO in coronary bifurcation intervention was compared between 2 scoring systems. Results: The consistency between visual and QCA was from fair to moderate (weighted Kappa=0.22-0.44). Compared with Non-SBO group, SBO group had the higher degrees of pre-operative bifurcation stenosis and side branch stenosis before main branch stent implantation; larger bifurcation angle and vessel diameters in main/side branches, all P<0.01. The area of V-RESOLVE under ROC curve was 0.76(95%CI 0.71-0.81) which was similar to the area of RESOLVE under ROC curve:0.77 (95% CI 0.72-0.81), P=0.74, Hosmer-Lemeshow P=0.17. The patients were categorized into 2 conditions by V-RESOLVE: high risk (V-RESOLVE score≥12)and non-high risk (V-RESOLVE score<12), the incidence of SBO was higher in high risk patients (16.7% vs 4.3%), P<0.01. The incidences of SBO were similar in non-high risk patients by V-RESOLVE and RESOLVE (4.3% vs 3.4%), P=0.22 and in high risk patients (16.7% vs 18.0%), P=0.60. Conclusion: V-RESOLVE scoring system may predict the risk of SBO in patients with coronary bifurcation intervention.

Pulmonary blast injury has become the main type of trauma in modern warfare, characterized by externally mild injuries but internally severe injuries, rapid disease progression, and a high rate of early death. The injury is complicated in clinical practice, often with multiple and compound injuries. Currently, there is a lack of effective protective materials, accurate injury detection instrument and portable monitoring and transportation equipment, standardized clinical treatment guidelines in various medical centers, and evidence-based guidelines at home and abroad, resulting in a high mortality in clinlcal practice. Therefore, the Trauma Branch of Chinese Medical Association and the Editorial Committee of Chinese Journal of Trauma organized military and civilian experts in related fields such as thoracic surgery and traumatic surgery to jointly develop the Clinical treatment guideline for pulmonary blast injury ( version 2023) by combining evidence for effectiveness and clinical first-line treatment experience. This guideline provided 16 recommended opinions surrounding definition, characteristics, pre-hospital diagnosis and treatment, and in-hospital treatment of pulmonary blast injury, hoping to provide a basis for the clinical treatment in hospitals at different levels.

OBJECTIVE: To investigate the protective effects of curcumin(CUR) and its mechanism on a rat model of neurotoxicity induced by manganese chloride (MnCl₂), which mimics mangnism. METHODS: Sixty male SD rats were randomly divided into 5 groups, with 12 rats in each group. Control group received 0.9% saline solution intraperitoneally (ip) plus double distilled water (dd) H₂O intragastrically (ig), MnCl₂ group received 15 mg/kg MnCl₂(Mn²⁺ 6.48 mg/kg) intraperitoneally plus dd H₂O intragastrically, CUR group received 0.9% saline solution intraperitoneally plus 300 mg/kg CUR intragastrically, MnCl₂+ CUR1 group received 15 mg/kg MnCl₂ intraperitoneally plus 100 mg/kg curcumin intragastrically, MnCl₂+ CUR2 group received 15 mg/kg MnCl₂ intraperitoneally plus 300 mg/kg CUR intragastrically, 5 days/week, 4 weeks. Open-field and rotarod tests were used to detect animals' exploratory behavior, anxiety, depression, movement and balance ability. Morris water maze (MWM) experiment was used to detect animals' learning and memory ability. ICP-MS was used to investigate the Mn contents in striata. The rats per group were perfused in situ, their brains striata were removed by brains model and fixed for transmission electron microscope (TEM), histopathological and immunohistochemistry (ICH) analyses. The other 6 rats per group were sacrificed. Their brains striata were removed and protein expression levels of transcription factor EB (TFEB), mammalian target of rapamycin (mTOR), p-mTOR, Beclin, P62, microtubule-associated protein light chain-3 (LC3) were detected by Western blotting. Terminal deoxynucleotidyl transterase-mediated dUTP nick end labeling (TUNEL) staining was used to determine neurocyte apoptosis of rat striatum. RESULTS: After exposure to MnCl₂ for four weeks, MnCl₂-treated rats showed depressive-like behavior in open-field test, the impairments of movement coordination and balance in rotarod test and the diminishment of spatial learning and memory in MWM (P < 0.05). The striatal TH⁺ neurocyte significantly decreased, eosinophilic cells, aggregative α-Syn level and TUNEL-positive neurocyte significantly increased in the striatum of MnCl₂ group compared with control group (P < 0.05). Chromatin condensation, mitochondria tumefaction and autophagosomes were observed in rat striatal neurocytes of MnCl₂ group by TEM. TFEB nuclear translocation and autophagy occurred in the striatum of MnCl₂ group. Further, the depressive behavior, movement and balance ability, spatial learning and memory ability of MnCl₂+ CUR2 group were significantly improved compared with MnCl₂ group (P < 0.05). TH+ neurocyte significantly increased, the eosinophilic cells, aggregative α-Syn level significantly decreased in the striatum of MnCl₂+ CUR2 group compared with MnCl₂ group. Further, compared with MnCl₂ group, chromatin condensation, mitochondria tumefaction was alleviated and autophagosomes increased, TFEB-nuclear translocation, autophagy was enhanced and TUNEL-positive neurocyte reduced significantly in the striatum of MnCl₂+ CUR2 group (P < 0.05). CONCLUSION Curcumin alleviated the MnCl₂-induced neurotoxicity and α-Syn aggregation probably by promoting TFEB nuclear translocation and enhancing autophagy.

A population-based case-control study was conducted to evaluate the relative factors in the environments, agricultural works, outdoor activities, and the effectiveness of Lyme borreliosis (LB)- associated personal protective measures in Beijing. Thirty-four cases and 272 controls were personally interviewed by well-trained interviewers. Venous blood samples were taken from each subject. Sowing or harvesting in summer (OR=2.571, 95% CI: 1.109-5.962), living in house with weeding in the yard (OR=2.247, 95% CI: 1.062-4.755), and residence at the plain area (OR=2.630, 95% CI: 1.050-6.588) were the independent relative factors for seropositive LB. Wearing long pants and clothes with cuffs was the only protective behavior against tick bite (OR=0.186, 95% CI: 0.041-0.846). The findings showed that local farmers were easily infected with LB and almost no protective measure was taken against LB infection. Infection with LB was easier in residents of plain regions. Pets raising and outdoor activities were not the risk factors for infection with LB. Further studies are needed to fully understand the risk of infection with LB in China.
