Objective To analyze and evaluate the characteristics of cerebral sparganosis on MRI. Methods MRI appearances of 15 cases of cerebral sparganosis proven by pathology or serological test were retrospectively studied.Results A total of 21 lesions were found,some of them were single and some were multiple but asymmetrical.8 lesions were found in parietal lobe,6 in frontal lobe,2 in temporal lobe,2 in oceipital lobe,1 in basal ganglia,1 in cerebellar hemisphere and 1 in pons.The lesions carried slightly hypointense on T_1-weighted images and moderate hyperintense on T_2-weighted images.Most lesions showed pefilesional brain parenchyma edema.Enhanced MRI was performed in 10 cases,and all of them demonstrated abnormal enhancement such as peripheral ring-type,tortuous beaded shape or serpiginons tubular shape enhancement.Follow-up MR images in 6 eases were analyzed,and the location and shape of the lesions changed in 2 of them.Conclusion There are some specific MRI findings on cerebral sparganosis.Enhanced MRI and follow-up examination are important for the diagnosis of cerebral sparganosis.

Background In China,esophageal squamous cell carcinoma (ESCC) and gastric cardia adenocarcinoma (GCA) share susceptibility loci,but different rates of multiple primary cancer and male/female ratio suggest the proportion of familial cancer is not equal.Methods The percent of cases with a positive family history,median onset age,rate of multiple primary cancer,and male/female ratio associated with upper,middle,lower third ESCC and GCA were compared to reveal the proportion of familial cancer.The 7267 subjects analyzed constituted all ESCC and GCA cases in whom the cancer was resected with cure intention between 1970 and 1994 at the 4th Hospital of Hebei Medical University.Results A positive family history for cancer was most often associated with the multiple primary ESCC and/or GCA cases,e.g.with 42％ of the males and 59％ of the females.For upper,middle,lower third ESCC and GCA,the percent of cases with a positive family history decreased by 38.5％,26.3％,26.5％,and 11.2％ in males (P ＜0.000) and 25.0％,22.3％,23.9％,and 9.8％ in females (P ＜0.0001).Median onset age increased from 49,52,55,to 56 years old in males and from 50,53,55,to 56 years old in females (both P ＜0.0001) for upper,middle,lower third ESCC and GCA.Male/female ratio increased from 2.2,2.1,2.2,to 6.2:1 for upper,middle,lower third ESCC and GCA (P＜0.0001).For upper,middle,lower third ESCC and GCA,the percent of multiple primary cancers decreased from 21.2％,2.3％,2.2％,to 1.5％ in males and from 14.3％,2.4％,3.4％,to 3.1％ in females.The preponderance of males,smoking,drinking,or onset-age ≥50 years was significantly higher in GCA than in ESCC,and the difference in the rates of multiple primary cancers between the preponderant and the non-preponderant cases was significant in GCA,but not in ESCC,suggesting non-equal requirement for genetic susceptibility when environmental hazards did not exist.Conclusions The proportion of familial cancer in upper gastrointestinal carcinomas decreases by the priamry site of upper,middle,lower third esophagus and gastric cardia.Considering familial and sporadic cancers differ in preventability,screening strategy and recurrence,our findings have basic and clinical implications.

AIMTo search for new compounds with strong anti-inflammatory activity and low gastrointestinal (GI) side effects.

METHODSA series of p-(methanesulfonyl) styrene-linked cyclic ketone derivatives were synthesized. Their anti-inflammatory activities against xylene-induced mice ear swelling and carrageenan-induced rat paw edema were evaluated, and their GI side effects in the rats were examined.

RESULTSNine target compounds (ZA(1-9)) were obtained, and their structures were determined by IR, 1HNMR, MS and elemental analysis. Compared with controls diclofenac (DC) and rofecoxib (RC) , ZA(3, 5-9) showed no significant difference in anti-inflammatory activity against xylene-induced ear swelling in mice. ZA(3, 7, 8) showed potency comparable to DC and RC (P > 0.05) and ZA6 was more potent than DC and RC (P < 0.05) in the treatment of carrageenan-induced rat paw edema. ZA(3, 5-9) showed less GI side effects than DC (P < 0.05, P < 0.01) and no significant difference compared with RC (P > 0.05).

CONCLUSIONp-(Methanesulfonyl) styrene-linked cyclic ketone derivatives showed strong anti-inflammatory activity but few GI side effects and deserve to be further investigated.

The aim of the present study was to investigate the effect of glucagon-like peptide-1 (GLP-1) on palmitate-induced apoptosis of human umbilical vein endothelial cells (HUVECs) and the underlying mechanism. HUVECs were cultured in vitro, and then treated by palmitate to induce apoptosis. Meanwhile, GLP-1 was added to explore its effect. After 24 h of the treatments, Caspase-3 activity and DNA fragmentation were measured using ELISA kits. Phospho-p38 mitogen-activated protein kinase (p-p38 MAPK) expression was detected by Western blot. The results showed that incubating HUVECs with 0.125 mmol/L GLP-1 increased Caspase-3 activity and DNA fragmentation. GLP-1 significantly inhibited palmitate-induced increases of Caspase-3 activity and DNA fragmentation in a concentration-dependent manner. Moreover, GLP-1 inhibited the up-regulation of p-p38 MAPK expression induced by palmitate in HUVECs. These results suggest GLP-1 protects HUVECs against lipo-apoptosis, and this effect may be mediated through inhibiting p38 MAPK pathway.

BACKGROUNDIn China, esophageal squamous cell carcinoma (ESCC) and gastric cardia adenocarcinoma (GCA) share susceptibility loci, but different rates of multiple primary cancer and male/female ratio suggest the proportion of familial cancer is not equal.

METHODSThe percent of cases with a positive family history, median onset age, rate of multiple primary cancer, and male/female ratio associated with upper, middle, lower third ESCC and GCA were compared to reveal the proportion of familial cancer. The 7267 subjects analyzed constituted all ESCC and GCA cases in whom the cancer was resected with cure intention between 1970 and 1994 at the 4th Hospital of Hebei Medical University.

RESULTSA positive family history for cancer was most often associated with the multiple primary ESCC and/or GCA cases, e.g. with 42% of the males and 59% of the females. For upper, middle, lower third ESCC and GCA, the percent of cases with a positive family history decreased by 38.5%, 26.3%, 26.5%, and 11.2% in males (P < 0.000) and 25.0%, 22.3%, 23.9%, and 9.8% in females (P < 0.0001). Median onset age increased from 49, 52, 55, to 56 years old in males and from 50, 53, 55, to 56 years old in females ( both P < 0.0001) for upper, middle, lower third ESCC and GCA. Male/female ratio increased from 2.2, 2.1, 2.2, to 6.2:1 for upper, middle, lower third ESCC and GCA (P < 0.0001). For upper, middle, lower third ESCC and GCA, the percent of multiple primary cancers decreased from 21.2%, 2.3%, 2.2%, to 1.5% in males and from 14.3%, 2.4%, 3.4%, to 3.1% in females. The preponderance of males, smoking, drinking, or onset-age ≥ 50 years was significantly higher in GCA than in ESCC, and the difference in the rates of multiple primary cancers between the preponderant and the non-preponderant cases was significant in GCA, but not in ESCC, suggesting non-equal requirement for genetic susceptibility when environmental hazards did not exist.

CONCLUSIONSThe proportion of familial cancer in upper gastrointestinal carcinomas decreases by the primary site of upper, middle, lower third esophagus and gastric cardia. Considering familial and sporadic cancers differ in preventability, screening strategy and recurrence, our findings have basic and clinical implications.

Objective: To observe the effects of acupuncture plus spinal manipulations on the physical functioning and levels of alkaline phosphatase (ALP), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and osteoprotegerin (OPG) in patients with ankylosing spondylitis (AS). Methods: A total of 128 AS cases were allocated into a control group and an observation group using random number table method, with 64 cases in each group. Patients in both groups took sulfasalazine and meloxicam. Patients in the observation group received additional acupuncture plus spinal manipulations. The efficacy, Bath AS functional index (BASFI), Bath AS disease activity index (BASDAI), and the levels of ALP, ESR, CRP and OPG were compared between the two groups after eight weeks of treatment. Results: After treatment, the symptom scores of traditional Chinese medicine in both groups were decreased (all P<0.05), and these scores in the observation group were significantly lower than in the control group (all P<0.05); the VAS, BASFI and BASDAI scores in both groups were decreased (all P<0.05), and these scores in the observation group were significantly lower than in the control group (all P<0.05); and the ALP, ESR, CRP and OPG levels in both groups were decreased (all P<0.05), and these levels in the observation group were significantly lower than in the control group (all P<0.05). The total efficacy rate was 92.2％ in the observation group, versus 78.1％ in the control group, presenting a statistical significance (P<0.05). Conclusion: Conventional medication combined with acupuncture and spinal manipulations can improve clinical symptoms, accelerate the recovery of physical functioning, and reduce the ALP, ESR, CRP and OPG levels.
