A total of 154 sera from patients with nasopharyngeal carcinoma(NPC), patients with other head and neck tumors(OHNT) and healthy individuals (HI) from Shaanxi province were tested for IgA antibody to EB viral capsid antigen (VCA-IgA) by immunoenzyrnie method. 75.93% of 54 pretreated NPC patients had VCA-IgA antibody with a GMT of 1: 38. 00,whereas less than 12. 00%of 50 OHNT and 50 HI with a GMT of 1: 2. 5 ～ 1: 3. 35.The results showed that the detection of VCA-IgA was of great value in diagnosis of NPC from low risk areas. The elevated level of VCA-IgA was seen in well-differentiated squamous cell carcinoma which gave a pattern similar to that noted in vacuolar nuclear cell carcinoma or less-differentiated carcinoma, but not in undifferentiated carcinoma. The VCA-IgA positive ratio in NPC patients below 30-year-old was similar to that in OHNT, however the GMT was elevated markedly. The results above showed that VCA-IgA antibody was of little value in diagnosis of NPC below 30-year-old and undifferentiated carcinoma.

[Objective]To apply interal fixation with new pterygo-shape titanium mesh cage in the treatment of degenarative cervical spondylosis.[Method]Twenty-seven patients of degenarative cervical spondylosis were reconstructed after vertecotomy with the cage including 19 cases of CDH,8 cases of OPLL,18 cases in male and 9 cases in female;single segment degenaration were 21 cases,double segment degenaration were 6 cases.All cases were excluded fracture,dislocate by X-ray and MRI preoperatly.[Result]All 27 patients were followed up for an average time of 10 months(from 6 to 14 months).The anverage time of bone graft fusion was 10 weeks.[Conclusion]The pterygo_shape titanium mesh cage can provide immediate biomechanical stability and prevent the mesh cage displace,subsidence,exodus after operation.The surgical procedure is simple,safety and without illic-bone graft,meanwhile can greatly relieve patients' economy burden.Then the internal fixation is elastic fixation,the bone fusion shows a satisfactory result.

OBJECTIVETo compare the difference in the efficacy between acupuncture and oral administration of trazodone and the expressions of neurotransmitters in patients of insomnia differentiated as liver stagnation transforming into fire.

METHODSSeventy patients of insomnia differentiated as liver stagnation transforming into fire were randomized into an observation group and a control group, 35 cases in each one. In the observation group, acupuncture therapy was adopted at Shenmen (HT 7), Baihui (GV 20), Yintang (GV 29), Hegu (LI 4), Taichong (LR 3), etc. The needles were retained for 20 min each time. The treatment was given once a day, the treatment of 2 weeks made one session. In the control group, trazodone, 100 mg, oral administration, once a day, the treatment of 2 weeks made one session. Two sessions were required in the two groups. The scores in Pittsburgh sleep quality index (PSQI) and Asberg rating scale for side effects (SERS), the levels of neurotransmitters such as 5-hydroxy tryptamine (5-HT) and norepinephrine (NE) and the expressions of protein kinase C (PKC) and brain-derived neurotrophic factor (BDNF) in peripheral blood were observed before and after treatment in the two groups.

RESULTSPSQI score and SERS score after treatment were all decreased compared with those in both groups before treatment (both P<0. 05). After treatment, PSQI score and SERS score in the observation group were lower apparently than those in the control group (both P<0. 05). After treatment NE content and PKC level were decreased; 5-HT content and BDNF mRNA were increased compared with those in both groups before treatment (all P<0. 05). NE content and PKC level in the observation group were lower apparently than those in the control group (both P<0. 05). The serum 5-HT content and BDNF mRNA expression in the observation group were higher than those in the control group separately (both P<0. 05).

CONCLUSIONAcupuncture therapy improves the sleeping quality of patients of insomnia differentiated as liver stagnation transforming into fire, and reduces serum NE level and increases 5-HT content and BDNF expression, which achieves the better efficacy as compared with the oral administration of trazodone. It is one of the effective approaches to the treatment of insomnia differentiated as liver stagnation transforming into fire.

ObjectiveTo explore the value of acupuncture in treating insomnia due to stagnated liverqi transforming into fire and its theoretical foundation, by observing the treatment effect of acupuncture in treating insomnia due to stagnated liverqi transforming into fire and its influence on 5-hydroxy tryptamine (5-HT) content.MethodTotally 187patients with insomnia due to stagnated liver qi transforming into fire were selected and randomized into two groups. The 93 cases in the control group were intervened by orally taking Trazodone, 100 mg for each dose, twice a day, 10 d as a course, totallyfor 2 courses; the 94 cases in the observation group were intervened by acupuncture at Shenmen (HT7), Baihui (GV20), Yintang (GV29), Hegu (LI 4), and Taichong (LR 3), once a day, 10 d as a treatment course, totally for 2 courses. Peripheral blood was collected from the two groups before and after intervention to detect the change of 5-HT content. Meanwhile, the Pittsburgh Sleep Quality Index (PSQI), Hamilton Depression Scale (HAMD, 24-item version), Asberg Rating Scale for Side Effects (SERS), and clinicalefficacies were assessed.ResultThe difference in 5-HT content between the two groups was statistically insignificant before intervention (P>0.05); 5-HT contents were significantly increased in both groups after intervention (P<0.05), while the content in the observation group was markedly higher than that in the control group (P<0.05); after treatment, the PSQI and HAMD scores were decreasedin both groups (P<0.05), while the PSQI, HAMD, and SERS scores in the observation group were markedly lower than those in the control group (P<0.05);the total effective rate was 92.6% in the observation group, significantly higher than 81,7% in the control group (P<0.05). ConclusionAcupuncture can significantly down-regulate 5-HT content in insomnia patients, and its total effective rate is higher than that of medication.

Objective To investigate effects and its mechanisms of hypertonic saline hydroxyethyl starch 200/0.5 solution on intracranial pressure and brain water content in rats with ischemic cerebral edema.Methods All experiments were conducted in the animal experimental center of Sun Yat-sen University.The 28 male Sprague-Dawle (SD) rats were randomly (random number) divided into hypertonic saline hydroxyethyl starch group,hydroxyethyl starch group,control group and sham operation group,each n =7.Ischemic cerebral edema model was reproduced by middle cerebral artery occlusion (MCAO),followed by reperfusion after ischemia for 2 hours (If the moldel was not successful,other rats were operated to fill the missing models).Then reperfusion after ischemia 2 hours and received hypertonic saline hydroxyethyl starch and hydroxyethyl starch via tail vein at the beginning of reperfusion.The colloidal osmotic pressure (COP) and intracranial pressure (ICP) were evaluated on 0,2,6,12,18,24 hours after the surgery.The water content of the right hemisphere was measured on 24 h after the surgery.Results The ICP of hypertonic saline hydroxyethyl starch group,hydroxyethyl starch group and control group were significantly higher than that of sham operation group on 2,6,12,18,24 h after the surgery.The ICP of hypertonic saline hydroxyethyl starch group was significantly lower than those of hydroxyethyl starch group and control group on 2,6,12,18 and 24 h.But there was no significant difference in ICP of the hydroxyethyl starch group compared with that of control group at all time points.The COP of hypertonic saline hydroxyethyl starch group and hydroxyethyl starch group were significantly higher than the control group and sham operation group at each time point; There was no significant difference in COP (mmHg) of the hydroxyethyl starch group compared with that of hypertonic saline hydroxyethyl starch group at all time points.The brain water content (BWC) of hypertonic saline hydroxyethyl starch group,hydroxyethyl starch group and control group were significantly higher than that of sham operation group on 24 hours after the surgery [(81.24±0.36)％,(83.04±0.10)％,(83.14±0.41)％ vs.(78.37±0.37)％,all P=0.000],BWC of hypertonic saline hydroxyethyl starch group lower than these of hydroxyethyl starch group [(81.24±0.36)％ vs.(83.04 ±0.10) ％,P =0.000] and control group [(81.24 ±0.36)％ vs.(83.14 ±0.41) ％,P =0.000].There was no significant difference in BWC of the hydroxyethyl starch group compared with that of control group [(83.04 ± 0.10) ％ vs.(83.14 ± 0.41) ％,P =0.578].Conclusion Hypertonic saline hydroxyethyl starch solution could significantly ameliorate ischemic cerebral edema and reduce ICP,but the relationship between its elevated COP and reduced ICP has not been confirmed.

Objective To observe the influence of Sishen Pill on the NF-κB p65 mRNA and protein expressions of colonic mucosa in rats with experimental ulcerative colitis (UC), and identify its underlying mechanism of action. Methods The experimental rats were divided into blank group, model group, Sishen Pill group and SASP group. The models were prepared by TNBS/ethanol enema. Sishen Pill group was intragastrically administrated by Sishen Pill extract 5 g/kg, SASP group by SASP 0.3 g/kg, and blank group and model group by equal volume of normal saline. The morphological injury of colonic mucosa was observed and scored with the naked eyes, and NF-κB p65 gene and protein expression were detected by RT-PCR and immunohistochemical method. Results Inflammation and ulceration on the colonic mucous membrane were found in the model group by naked eyes, and had significant difference with the blank group (P<0.05). The relative expression amount of NF-κB p65 gene and protein of colonic tissues were increased in the model group compared with the blank group (P<0.01). Compared with the model group, the relative expression amount of NF-κB p65 gene and protein in Sishen Pill group were decreased (P<0.05, P<0.01). Conclusion Sishen Pill has effect for treating UC, which is probably related to the activation of NF-κB signal transduction pathway.
