OBJECTIVETo determine the recognition of healthy medical students on deqi after acupuncture, reveal the qualitative and quantitative rules of deqi and understand whether these rules are the factors of the clinical application of acupuncture therapy.

METHODSThe class questionnaires were used for the investigation study on the understanding of deqi after acupuncture at Hegu (LI 4) or Zusanli (ST 36) in 86 healthy students in the clinical medicine class.

RESULTS(1) Deqi was a kind of complicated compound feelings, with many sensation qualities such as distending pain, distension and pain. (2) Deqi was a kind of mild and moderate sensations. In 10-score credit sys tem of Massachusetts General Hospital acupuncture sensation scale (MASS), the scores of distending pain (4.69 +/- 2.83), distension (4.39 +/- 2.91) and soreness and distension (3.93 +/- 2.93) were around 5 (moderate degree), the scores of stabbing pain (1.89 +/- 2.02) were around 2 (mild degree). (3) The differences in the quantitative scores were significant for stabbing pain, distending pain, distention, soreness and distention and the others before and after treatment (all P<0.05).

CONCLUSIONDeqi of acupuncture is the mild and moderate complicated sensations manifested as distension, soreness, pain and numbness. As the invasive therapy, the filiform needle puncture will bring a certain psychological impacts on the receptors. The subjective sensation is possibly the factor for the patients' selection of acupuncture treatment.

Objective To describe the CT features of giant lymph node hyperplasia in abdomen.Methods A retrospective study of CT features of giant lymph node hyperplasia in abdomen confirmed by surgery or biopsy pathology was performed.CT findings of all lesions were assessed by two radiologists including size,location,pattern of enhancement and density characteristics.Results 1 2 patients with giant lymph node hyperplasia in abdomen were confirmed including 7 women and 5 men with age range from 11 to 75 years (median age 3 9 years).All patients underwent pre-and post-contrast enhanced CT.CT showed a single mass in 9 patients lo-cated at retroperitoneum in 5,porta hepatic in 2,and mesentery in 2.Multiple masses were located at chest,abdomen and neck in 3.The lesions ranged in size from 1.2 to 11.9 cm in maximum diameter with an average size of 3.7cm.CT showed all lesions with well-defined margin and regular shape.The lesions less than 5 cm in diameter usually showed homogeneous enhancement,and how-ever those more than 5 cm showed heterogeneous enhancement.The calcification was seen in two patients.Conclusion CT features of giant lymph node hyperplasia in abdomen are characteristic.

As a kind of additive in feed of monogastric animals, the application of natural phytase is limited due to its disadvantages. In this paper, the strategies of phytse reform was introduced. Furthermore, the research and progress on protein engineering of feed phytase was reviewed, including phytase over-expression, phytase thermostability, catalytic efficiency and optimum pH.

Objective To analyze the distribution and clinical characters of cyanotic congenital heart diseases in newborns.Method We examined the suspicious cases with color doppler ultrasonic cardiogram(CFM),and compared with the results of autopsies.Results The most common congenital diseases in the group were complete transposition of the great arteries,with the proportion of 34.4%, and most of them were compounded cardiovascular disorders. The most common symptom was cyanosis, took the proportion of 84.3%; some patients had no cyanosis, tachypnea and murmurs.The cases with cardiovascular disorders most were combined with type Ⅱrespiratory failure and metabolic acidosis.Conclusions There are many types of congenital heart diseases, the symptoms are untypical,so the suspicious cases shall examine with CFM as early as possible.

Objective To detect the levels of anti-gliadin IgA and anti-gliadin IgG antibodies in the plasma of the patients with schizophrenia, and to investigate the association between schizophrenia and anti-gliadin IgA, IgG bodies in a Chinese Han population, and to clarify the effect of gliadin on the occurrence of schizophrenia.Methods The plasma samples were collected from 428 patients with schizophrenia and 555 cases of normal control subjects in a Chinese Han population.The gliadin antibodies in plasma,including IgA and IgG,were tested using a native anti-gliadin ELISA test kit.The positive rates of plasma anti-gliadin IgA,and anti-gliadin IgG were tested by Chi-square test between the patients with schizophrenia and control subj ects. The differences of the levels of anti-gliadin IgA and anti-gliadin IgG were tested by Mann-Whitney U test between the patients with schizophrenia and control subjects.Results Compared with normal control group,the anti-gliadin IgA level and the positive rate of plasma anti-gliadin IgA in patient group were increased significantly(P<0.01),but there were no significant differences of the positive rate and the level of anti-gliadin IgG in plasma between patient and control groups (P>0.05).The anti-gliadin IgA levels in the patients with delusion of observation,delusion of being revealed,delusion of persecution, delusion of j ealousy, delusion of grandeur, incoherence of thinking, illogic thought, bizarre behavior,aggressive behavior,hallucination-delusion syndrome,poverty of thought,emotional blunting/apathy and aboulia were higher than that of the normal controls (P<0.05);the anti-gliadin IgG levels in the patients with delusion of being revealed and delusion of grandeur were higher than that of the normal controls (P<0.05 ). Conclusion Gliadin is associated with the onset of schizophrenia in Chinese Han population, and the plasma antibodies of gliadin maybe play an important rale in the onset of schizophrenia.

Objective To explore the relationship between pulse wave velocity(PWV)and blood pressure classification and cardiovascular risk factors stratification in patients with essential hypertension. Methods Totally,390 patients with essential hypertension were recruited in the study and their carotid- femoral PWVs were recorded by an automatic pulse wave velocity measurement system.The patients were stratified by their cardiovascular risk factors.PWVs were compared between patients with varied blood pressures or with and without cardiovascular risk factors.Results There was no significant difference in PWV between patients of phase 1 and phase 2 hypertension,[(10.8?1.7)m/s vs.(11.9?1.2)m/s,P =0.398].PWV in patients with more than one risk factor was significantly higher than that in those with hypertension alone,[(10.4?1.4)m/s vs.(11.7?1.4)m/s,P=0.018].Conclusions PWV in hypertensive patients with one or more than one other risk factors was significantly higher than that in those without other risk factors.Cardiovascular risk factor might play a more important role in arterial stiffness.

Objective To explore the skill of mien)surgical removal and preservation and functional recovery of facial nerve for large acoustic neuromas.Methods The clinical data of 82 consecutive patients with large acoustic neuromas operated upon through the suboccipital retrosigmoid approach were retrospectively reviewed.The cases with HB grade Ⅲ - Ⅵ of facial nerve were divided randomly into two groups,the one group was given conventional therapy and the other group was given Kabato rehabilitation training.Results In those cases,acoustic neuromas were totally removed in 77 (93.9%),subtotally removed in 5.Facial nerve was kept anatomically intact in 78 cases of the patients (95.1%).Recovery of facial nerve function was faster and more effective in the training group than that in the un-training group.During the follow-up ranging from 6 months to 3 years,among 5 cases of subtotally resection,2 cases relapsed.Three patients in our series complained of chronic headache postoperatively.No patient long time coma or died.Conclusion The goal of large acoustic neuromas treatment should be total removal in one stage and preservation of facial nerve function,as they determine a patient's quality of life.Kabat rehabilitation training is the effective method of functional recovery of facial nerve after operation.

Objective To summarize the clinical characteristics and therapeutic approaches of Kasabach-Merritt syndrome (KMS).Methods The data from 17 KMS patients that had been definitely diagnosed from December,2007 to January,2012 in our tertiary center were collected retrospectively.Results We described 17 patients,13 of whom were male and 4 of whom were female,with an age range of 17 hours to 28 days.Of the 17 cases,4 cases had hemangioma of internal organs,13 on the surface of the body.All of them had thrombocytopenia and coagulation dysfunction.Seventeen cases were initially treated with corticosteroids.The responses were varied:excellent and rapid improvement (n =6),failure (n =11),recurrence (n =3).Then the cases of failure and recurrence accepted artery embolization:excellent and rapid improvement (n =8),failure (n =4),recurrence (n =1),with 1 giving up.At last,the cases resistant to artery embolization therapy accepted vincristine therapy.Four cases had rapid improvement,and 1 died from disseminated intravascular coagulation.In this study,a response rate to corticosteroids was 35.3％,and the recurrent rate was 50％.The response rate to artery embolization was 61.5％.Five patients unresponsive to hormone therapy and artery embolism were treated with vincristine,and the effective rate was 80％.Conclusion In the therapy of neonatal KMS,the resistant to corticosteroids is common.Combinative therapy of corticosteroids with artery embolization is recommended as the first-line therapy.Vincristine is suggested as a therapy when there is resistance to the other therapy.

Objective To investigate the clinical features and characteristics of coronary artery lesion between Hui and Han nationality young pa?tient with acute myocardial infarction(AMI)who were referred to the affiliated hospital of Ningxia Medical University. Methods A total of 189 con?secutive AMI young patients(age≤44 years)who underwent coronary angiography were retrospectively retrieved from the database.Those patients with AMI were divided into Hui group(46 cases)and Han group(143 cases). The clinical features and results of coronary angiogram were com?pared between the two group. Results Compared with Han group,Hui group are more younger than Han group,high prevalence rate of diabetes, lower smoking history and lower drinking history(P<0.05). Coronary angiography showed the incidence of three?vessel lesions was significant low?er in Han group than in Hui group(P<0.05). Both group showed single vessel was the most common lesion. Conclusion Hui nationality patients with acute myocardial infraction are more younger and are are more prone to suffering from diabetes history、lower smoking history and lower drinking history than Han nationality patients. The coronary artery lesions of Hui nationality patients with acute acute myocardial infraction are more three?branch lesions than Han nationality patients.
