Objective To investigate the clinicopathological features of primary gastric malignant lymphoma.Methods 32 cases of primary gastric non Hodgkin's malignant lymphoma(NHL)were studied by clinicopathology,immunohistochemistry and ultrastructure.Results 3 cases of NHL arose from fundus of stomach,7 cases from body of stomach,8 cases from gastric angle,and 14 cases from gastric antrum.The paraffin sections of all cases were stained.There were 31 cases(96\^9%)exhibiting B cell phenotype,only 1 case(3\^1%)exhibiting T cell phenotype.11 cases of NHL and 6 cases of undifferentiated carcinoma(UC)in stomach were observed comparatively under electron microscope(EM).The ultrastructural characteristics of NHL were much different from those of UC.Conclusion Most primary gastric malignant lymphoma are B cell lymphomas.Immunohistochemistry and ultrastuctural observation are much helpful in the diagnosis and differential diagnosis between NHL and UC.

[Objective]To determine the efficacy and characteristics of percutaneous vertebroplasty in treating patients with vertebral osteoporosis fractures combined with intraosseous cyst.[Method]Thirteen cases of vertebral osteoporosis fractures combined with intraosseous cyst were performed with percutaneous vertebroplasty.Bone cement containing appropriate proportion allograft bone powder were injected to vertebral body according to the sererity of osteoporosis and the size of intraosseous cyst.[Result]According to standard of World Health Organization about pain,complete pain relief was in 10,partial in 2,and slight in 1 patient.One case developed bone cement leakage into the paravertebral soft tissues during operation,but there were no clinical signs and symptoms.The next vertebral body fracture was found at sixteen days after percutaneous vertebroplasty in 1 case,and percutaneous vertebroplasty was repeated to relieve his pain.This patient was followed-up for 1 year,and no refracture was observed.[Conclusion]Vertebral osteoporosis fractures combined with intraosseous cyst is a special disease in elderly population.Percutaneous vertebroplasty is effective and it shouled be the first option for treatment of patients with vertebral osteoporosis fractures combined with intraosseous cyst.The complications could be reduced by local treatment combined with anti-osteoporosis drugs and correct rehabilitation.

Objective To observe the therapeutic efficacy of acupuncture at the interiorly-exteriorly related meridians plus rehabilitation training in treating post-stroke shoulder-hand syndrome. Methods Sixty eligible patients with post-stroke shoulder-hand syndrome were randomized into a treatment group and a control group, 30 in each group. The treatment group was intervened by acupuncture at the interiorly-exteriorly related meridians plus rehabilitation training, while the control group was by rehabilitation training alone. After 2 treatment courses, the Fugl-Meyer Assessment (FMA), visual analogue scale (VAS) and edema score were observed and compared. Results The FMA, VAS, and edema scores were significantly changed in both groups after intervention (P＜0.01). There were significant differences in comparing the FMA, VAS, and edema scores between the two groups after intervention (P＜0.05). The total effective rate was 83.3%in the treatment group versus 76.7%in the control group, and the difference was statistically significant (P＜0.05). Conclusion Acupuncture at the interiorly-exteriorly related meridians plus rehabilitation is an effective method in treating post-stroke shoulder-hand syndrome.

Obiective To evaluate the current status of studies on interventional recallalization of fallopian tube.Methods According to the standard of evidence-based medicine,literatures were analyzed by two readers in three time periods:1997 to 2000,2001 to 2004 and 2005 t0 2008.Two separate evaluation results were tested by the statistical method Kappa to test its consistency.Scores of clinical controlled trials (CCT)and randomized controlled trials(RCT)were calculated according to Jadad score scale.The accurate criteria of case selection,case exclusion,and effect determination;the method of randomization;the number of samples:the comparability of baseline;the blinded procedure;the therapeutic method;the method of statistical analysis:the follow-up cases; the drop-out cases and the conclusions derivation of RCT and CCT into descriptive analysis were evaluated Results One hundred and fifty seven therapeutic articles were searched and 30 RCT and CCT articles(25 RCT and 5 CCT)were analyzed.The Kappa value was 0.85 and P＜0.05 indicating that the evaluation was in good consistency.2,15 and 8 RCT received 0 point,1 point and 2 points respectively in Jadad score scale.RCT and CCT contained 9 articles(30.0%)fulfilled the accurate criteria of case selection and exclusion:12 articles(40.0%)met the accurate criteria of effect determination:4 articles(13.3%)utilized the definite method of randomization;27 articles (90.0%)had the number of sample beyond 60;14 articles(46.7%)met the baseline comparability;only 1 article(3.3%)used the single-blinded method,17 articles(56.7%)utilized the method of statistical analysis;13(43.3%)mentioned follow-up in articles;4(13.3%)mentioned drop-out cases in the articles and 14(46.7%)articles had the conclusions derived by considering the statistical significance and clinical significance.Conclusion The quality of studies on interventional recanalization of fallopian tube is poor and could not meet the standard of evidence-based medicine.

BACKGROUND: Osteolysis has always occurred in pelvis. Percutaneous injection of bone cement stabilized bone fracture, relieved pain or even treated tumor. However, leakage of bone cement might cause severe complications. OBJECTIVE: To explore the therapeutic effect of peroutaneous injection of bone cement on treating osteolysis pelvic disease in 9 cases by the CT guidance. METHODS: By the CT guidance, needing degree was determined firstly. Focal size and scanning layers were used to calculate focal volume and estimate injected dose of bone cement. Three-dimensional targeting device was used to introduce the puncturation. The bone cement which was 0.2-0.5 mL less than the calculated volume was injected into osteolysis site. The accuracy, injected dose, clinical efficacy, and complications were investigated. RESULTS AND CONCLUSION: The following-up ranged from 5 months to 4 years, with mean duration of 1.5 years. At 1-48 hours after operation, symptoms were recovered, including complete recovery (n=6), partial recovery (n=2), and light recovery (n=1). Leakage of bone cement was not detected out around focal region. This suggested that percutaneous injection of bone cement into the erosion site is an effective method to treat pelvic osteolysis disease, characterizing by security, effective, and less invasive.

Objective To evaluate the relationship between the concentration of pentane in the exhaled air and degree of the lung injury in non-heart-beating (NHB) rabbits.Methods Twenty-four healthy male Japanese white rabbits weighing 2.4-3.0 kg were randomly divided into 4 groups ( n =6 each):A,B,C and D groups.The NHB model was established by exsanguination through the femoral artery.The exhaled gases were collected and lung tissues were removed at 0,30,60 and 120 min after cardiac arrest in A,B,C and D groups respectively.The concentration of pentane in the exhaled gases was detected immediately using the gas chromatography-mass spectrography.The wet to dry (W/D) lung weight ratio and content of malondialdehyde (MDA) in lung tissues were measured.The lung injury score (LIS) was recorded.The maximal volume ( Vmax ) of the lung was recorded when the airway pressure reached 30 cm H2O.Results Compared with groups A and B,the exhaled pentane concentration was significantly increased in group C,and the W/D ratio,content of MDA and LIS were significantly increased,while Vmax was significantly decreased in group D ( P ＜ 0.05).Compared with group C,W/D ratio and LIS were significantly increased in group D ( P ＜ 0.05 ).Conclusion The concentration of exhaled pentane can not reflect the degree of the lung injury in NHB rabbits.

The clinical data of 143 patients with type Ⅱ a hepatolithiasis with normal function of the sphincter of Oddi were analyzed.The patients were divided into two groups at random.The data of the 2 groups of patients were compared on the operating time,hospitalization,rates of complication,residual stone rates and recurrence rates.The A group patients underwent laparoscopic video choledochoscopic hepaticocholangiolithotomy,T-tube drainage and choledochoscopic lithotomy.The B group patients underwent laparoscopic video hepatectomy and choledochoscopic lithotomy.For most of the patients in the A group,the treatment had the advantages of less trauma,less complications and quicker recovery.There was no significant differences in residual stone rates and recurrence rates between the two groups.As it was difficult to remove stones in the caudate lobes of Ⅱ a type patients in A group due to the sharp angle between the hepatic duct and bile ducts of the caudate lobe,individualized programs should be adopted according to the location of stones on individual patients.

To analyze the relationships among syndrome, therapeutic method and Chinese herbal medicine in patients with coronary artery disease (CAD).

OBJECTIVE: To explore the effect of delta-opioid receptor (DOR) in electroacupuncture (EA) protecting the brain against acute ischemic injury. METHODS: Fifty-one rats were randomly divided into sham ischemia group, ischemia group, sham EA group, EA group, and EA+DOR antagonist (naltrindole) group. Transient focal cerebral ischemia (1 hour) was induced in rat brain by middle cerebral artery occlusion (MCAO) method. EA was applied on Shuigou (GV 26) and Neiguan (PC 6) for 30 min, starting immediately after the onset of reperfusion. Neurological deficit scores and volume of cerebral infarction were detected after 24-hour reperfusion. Other 12 rats were randomly divided into sham ischemia group, ischemia group, EA group and EA + naltrindole group. DOR protein expressions were assessed by Western blotting after 24-hour reperfusion. RESULTS: In comparison with the ischemia group and sham EA group, EA significantly reduced ischemic infarction and neurological deficits (P<0.05); EA significantly increased the expression of 60 kD DOR protein (P<0.05) and tended to increase that of 36 kD DOR protein (P>0.05). When naltrindole was combined with EA, the naltrindole completely abolished the EA-induced protection in ischemic infarction and neurological deficits, and also arrested the expression of DOR. CONCLUSION: EA can up-regulate DOR expression and protect the brain from ischemia-reperfusion injury.
