Objective To explore the effect of surgical treatment on primary gastrointestinal non-Hodgking lymphoma(NHL) in children.Methods Nine cases of clinical and follow-up data of primary gastrointestinal NHL were studied retrospectively to evaluate the effect of surgical treatment on primary gastrointestinal NHL in children.Results Seven cases were male and 2 cases were female.The mean age was(5.59?3.27)years old.The clinical manifestation included abdominal mass (7 cases),abdominal pain (5 cases),fever (2 cases),haematemesis and melena (2 cases),constipation (1 case) and paroxysmal abdominal pain with vomiting (1 case).Nine cases were diagnosed as primary gastrointestinal NHL,including 1 case of intussusception,1 case of acute appendicitis,2 cases of gastrointestinal obstruction,2 cases of gastrointestinal bleeding and 3 cases of abdominal mass.One case received the operation of intussusception reduction,tumor resection and intestinal anastomosis.One case received appendectomy.One case received the operation of tumor biopsy and transverse colon colostomy.Six cases received laparotomy.Six cases were diagnosed as Burkitt lymphoma.One case was anaplastic large cell lymphoma and 2 cases were diffuse large B-cell lymphoma.One case was at stage Ⅰ,1 case was at stage ⅠE,2 cases were at stage Ⅱ,3 cases were at stage ⅡE and 2 cases were at stage Ⅲ.Nine patients had received operation.One case died after operation and 8 cases had received combined chemotherapy.The 1 and 3 years survival rates were 75.0% and 37.5%,respectively.Conclusions Acute abdomen is often the first symptom of primary gastrointestinal NHL in children and comprehensive surgical treatment is an effective procedure for it.

Objective To characterize non-headache symptoms during the migraine attack phase in migraine patients. Methods We enrolled in the present investigation 71 patients with migraine with and without aura who had sought medical treatment in our department from January 2010 to January 2011. We used a self-made migraine questionnaire to investigate associations of the non-headache symptoms with the sociodemographic factors, subtypes, severities and attacks of the headache in the patients. Results There were no significant differences in the number of non-headache symptoms among patients with different ages, genders, education levels, subtypes, severities, mean attack frequencies per month (P＞0.05). The most frequently reported non-headache symptoms were nausea (87.3％),phonophobia (81.7％) and mood change (69.0％).The incidences ofphonophobia,sleep disorder and osmophobia were significantly higher in patients without aura than in patients with aura (P＜0.05).Conclusion Migraine attacks are often accompanied by a variety of non-headache symptoms of which the most frequently reported ones are nausea,phonophobia and mood change.Patients without aura tend to have more phonophobia,sleep disorder and osmophobia than those with aura.

OBJECTIVETo observe the therapeutic efficacy of Qianggu Granule (QGG), Diacerein Capsule (DC), and QGG + DC in treating knee osteoarthritis (KOA, belonging to Gan-Shen insufficiency induced vein stasis syndrome), and to explore the clinical advantages of QGG + DC.

METHODSNinety patients in line with the diagnosis standard were randomly assigned to three groups, i. e., the QGG group (30 case, treated by QGG), the Western medicine treatment group (30 case, treated by DC), and the combination therapy group (30 case, treated by QGG +DC). Then the patients' symptoms and signs were scored. Meanwhile, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), tumor necrosis factor alpha (TNF-alpha), comprehensive efficacy, and adverse reactions, etc. were assessed.

RESULTSThe ache could be obviously alleviated, the patients' joint function could be improved, and their quality of daily activities could be elevated in all the 3 groups. There was statistical difference in the symptoms and signs scores, CRP, ESR, and TNF-alpha before and after treatment (P < 0.05). Better effects were obtained in the combination therapy group (P < 0.05). As for the comprehensive efficacy, it was better in the QGG + DC group than in the QGG group and the DC group, showing statistical difference (P < 0.01).

CONCLUSIONSThe comprehensive therapeutic efficacy of applying QGG + DC in treating KOA (belonging to Gan-Shen insufficiency induced vein stasis syndrome) was superior to using QGG or DC alone. Besides, no obvious adverse reaction occurred.

OBJECTIVETo study the renal protective effect of Xinganbao Capsule on rats with adriamycin induced nephropathy (AIN).

METHODSForty male SD rats were randomly divided into four groups, i.e., the normal control group (N), the AIN model group (M), the Benazepril group (B),and the Xinganbao Capsule group (X). AIN rat model was established by left unilateral nephrectomy and repeated caudal vein injection of adriamycin. Gastric perfusion of xinganbao Capsule (at the dose of 500 mg/kg per day) and Benazepril (at the dose of 4 mg/kg per day) was given to rats in the X group and the B group respectively one week after nephrectomy. Rats were sacrificed at the 8th week after medication. The 24-h urinary protein excretion (24 h-UP) and blood biochemical indices were determined. Renal tissues were collected for pathological changes under light and electron microscopes. Expressions of fibronection (FN), collagen IV (COL-IV), and osteopontin (OPN) in renal tissues were detected by immunohistochemistry. mRNA levels of transforming growth factor-beta 1 (TGF-beta1), tissue inhibitor of metalloproteinase-1 (TIMP-1), and plasminogen activator inhibitor-1 (PAI-1) were measured by fluorescent Real-time PCR.

RESULTSWhen compared with the model group, 24 h-UP, blood urea nitrogen (BUN), and serum creatinine (SCr), and blood lipids levels were significantly lowered in the X group. The mesangial matrix percentage was less in the X group than in the M group. Renal FN, COL-IV, and OPN expressions more significantly decreased in the X group than in the M group. Similarly mRNA expressions of TGF-beta1,, TIMP-1, PAl-1 in renal tissues obviously decreased.

CONCLUSIONXinganbao Capsule could exert its renal protective action possibly through reducing the urinary protein excretion, correcting lipid metabolic disturbance, inhibiting excessive accumulation of extracellular matrix, decreasing the expression of fibrosis factors, and improving the pathological damage of kidneys in the AIN rat model.

OBJECTIVETo improve the method for monitoring sleep state and respiratory rhythm of SD rats, providing a solution for rats' chewing on the wires, signal loss and instability problems in the animal model of sleep apnea syndrome (SAS).

METHODSWe improved monitoring electrodes of both electrocorticogram (ECoG) and electromyogram (EMG), signal circuit and animal operation.

RESULTSOperation time was shortened and wound exposure time was reduced, which made it easier for postoperative recovery. The ECoG and EMG signals were more stable with sharp image, and signal circuit lines had better conductivity and material durability, achieving continuous monitoring for a long time and high success rate. We could precisely distinguish the sleep wake state and the sleep apnea events in rats according to these signals.

CONCLUSIONThe improved method is more reliable and practical to test the small animal model of SAS, and is more easily to operate and the signals are more stable.

Objective: Our aim was to investigate the effects of phenylephrine (PH) and angiotensin Ⅱ (AT) on reperfusion arrhythmias in the isolated rat heart and its mechanism. Methods: Isolated rat hearts were subjected to dual coronary perfusion. After 15 minutes of aerobic perfusion of both coronary beds, flow to the left coronary bed infused selectively into that bed. Ventricular tachycardia (VT) and fibrillation (VF) were analyzed 5 minutes after reperfusion. Results: The reperfusion arrhythmias was significantly exacerbated by PH; however, AT alone did not have the same effect. The selective Na+/H+ exchanger (NHE) inhibitor, HOE642, which was infused along with PH, reversed the proarrhythmic effects of PH. The specific protein kinase C (PKC) inhibitor GF109203X (GF) infused along with PH can only partially reverse the proarrhythmic effect of PH. The AT2 receptor inhibitor PD123319 (PD) alone increased the incidence of reperfusion-induced arrhythmias. However, no statistical significance showed. Combination of PD and AT significantly increased the incidence of reperfusion-induced arrhythmias. Conclusion: Activation of α1-adrenoceptor can exacerbate reperfusion-induced arrhythmias. The AT1 receptor activated by AT can exacerbate reperfusion-induced arrhythmias. The activation of AT2 receptor may reduce reperfusion-induced arrhythmias.

Acupuncture anesthesia is a technique by partially or completely replacing anesthetics with acupuncture in surgery based on the traditional acupuncture analgesia mechanism.It emerged in the 1950s,went viral in the 1970s and then gradually fell into decline.In the recent years,this technique has regained attention and further research.Acupuncture anesthesia can be classified as either pure acupuncture anesthesia or acupuncture-medication combined anesthesia.To expand the application of this technique,a patient with non-ST elevation acute coronary syndrome in urgent need of percutaneous coronary intervention (PCI) received pure acupuncture anesthesia because of an allergy to lidocaine,and the operation went successfully.This is the first time that pure acupuncture anesthesia and coronary arteriography were combined,which is of great significance in further study and development of acupuncture anesthesia.
