Dendritic cells (DCs)are the most potent antigen presenting cells,which play crucial roles in initiating and amplifying both the innate and adaptive immune responses.In DCs' whole life,the dynamics of cytoskeleton is involved in the regulation of their deformation,migration,adhesion,endocytosis and antigen presentation.The cytoskeleton is a complex system and regulated by lots of cytoskeletal proteins.With the research going,our understanding on cytoskeleton system is getting clear.Based on these,we summarized the effects of filamentous actin (F-actin)cytoskeleton remodeling on the morphology and immune functions of DCs.

ObjectiveTo explore the relationship between flash visual evoked potentials (fVEP) and intracranial pressure (ICP), and the effect of fVEP on monitoring ICP treatment.MethodsICPs of 37 patients with large area cerebral infarction and intracranial hypertension were measured before and at 10 min, 20 min, 30 min, 40 min, 50 min and 60 min after mannitol treatment.ResultsThe mannitol effect to cure the large area cerebral was not well.ConclusionfVEP can monitor ICP exactly and harmless, and has importance value to instruct therapy of ICP in clinic.

OBJECTIVETo observe the protective effect of electroacupuncture (EA) at "Zusanli" (ST 36) on inflammatory injury induced by intestinal ischemia/reperfusion (I/R) in rats.

METHODSForty-eight Wistar rats were randomly divided into a sham injury group, a model group, an EA group and a sham EA group, 12 rats in each group. Intestinal I/R rat models were established by method of clamping with occlusion of superior mesenteric artery (SMA) for 45 min followed by reperfusion. The EA group was treated with EA (2.5 mA, 2 Hz/100 Hz, 0.5 h) at "Zusanli" (ST 36) 30 min before reperfusion, and at the same time, the sham EA group was treated with fast insertion at two non-meridian acupoints on skin surface (2 cm horizontally away from linea alba abdominis and about 5 cm paralleled to cartilago ensiformis downward). No interventions were added on the sham injury group and the model group. The degree of pathological injury in intestines, water rate of intestines, diamine oxidase (DAO) activity and intestinal mucosal blood flow (IMBF) were examined at 1 h and 3 h after reperfusion.

RESULTSAt 1 h and 3 h after reperfusion, the intestinal pathological injury in EA group was significantly attenuated compared with that in model group, and the intestinal water rate of (74.00 +/- 2.11)% and (78.78 +/- 0.80)% in EA group were significantly lower than (80.69 +/- 1.66)% and (83.17 +/- 2.08)% in model group (both P < 0.01), but DAO of (68.83 +/- 4.31) U/L and (47.84 +/- 5.57) U/L as well as IMBF of (152 +/- 5.8) PU and (139.8 +/- 6.1) PU in EA group were significantly higher than DAO of (32.86 +/- 4.72) U/L, (17.01 +/- 2.96) U/L as well as IMBF of (124.7 +/- 8.3) PU and (89.4 +/- 13.2) PU in model group (all P < 0.01). Meanwhile, the above mentioned changes in sham EA group showed no significant differences compared with those in model group (all P > 0.05).

CONCLUSIONElectroacupuncture can not only reduce the inflammatory injury induced by intestinal IR but also increase intestinal blood supply so as to protect the intestine function.

Objective To study the prevalence of mental disorders among the Chinese youths aged 15-34 years,in rural areas and to identify risk factors related to suicide.Methods A consecutive sampling strategy was used for suicidal cases in 16 randomly selected counties in Hunan,Liaoning,and Shandong provinces.Between 2005 and 2008,a total of 392 suicide cases were recruited with 416 community controls at the same age range,selected from the same areas one family member together with one close friend of each suicidal case were interviewed,using the psychological autopsy (PA) method.The same method with structured instruments was performed on the two informants for each control in the same community.SCID was used for the diagnosis of mental disease.Results 48.0％ of the suicides were diagnosed as having at least one mental disorder episode,in comparison with only 3.8％ among the controls.It was found that mental disorder was the most important risk factor for the Chinese young suicide cases in the rural areas.Conclusion As seen in the Western countries,mental disorder had also been the number one correlate on suicidal cases in China,with the difference as other social and psychological factors might have played relatively more important roles in China.

OBJECTIVETo observe analgesic effect of acupuncture anesthesia.

METHODSSixty-nine cases undergoing rectal cancer surgery were randomly divided into 3 groups, group I, II and III, 23 cases in each group. Both Zusanli (ST 36) and Sanyinjiao (SP 6) were selected for acupuncture anesthesia. Group I received general anesthesia after acupuncture induction, group II received acupuncture after general anesthesia, and group II received only general anesthesia. Minimum alveolar concentration (MAC) before and after operation was recorded.

RESULTSMAC was (1.35 +/- 0.19) vol% in the group I, (1.49 +/- 0.22) vol% in the group II and (1.64 +/- 0.27) vol% in the group III. Acupuncture before and after general anesthesia could decrease respectively by about 0.29% and 0.15% of MAC in rectal cancer surgery undergoing general anesthesia, with a very significant difference (P < 0.01) or a significant difference (P < 0.05) among the 3 groups.

CONCLUSIONAcupuncture anesthesia has a certain adjuvant action for anesthesia and analgesia, and acupuncture before general anesthesia has a better action.

AIMTo develop a high-throughput multiplex, fast and simple assay to scan azoospermia factor (AZF) region microdeletions on the Y chromosome and establish the prevalence of Y chromosomal microdeletions in Chinese infertile males with azoospermia or oligozoospermia.

METHODSIn total, 178 infertile patients with azoospermia (non-obstructed), 134 infertile patients with oligozoospermia as well as 40 fertile man controls were included in the present study. The samples were screened for AZF microdeletion using optimized multi-analyte suspension array (MASA) technology.

RESULTSOf the 312 patients, 36 (11.5%) were found to have deletions in the AZF region. The microdeletion frequency was 14% (25/178) in the azoospermia group and 8.2% (11/134) in the oligospermia group. Among 36 patients with microdeletions, 19 had deletions in the AZFc region, seven had deletions in AZFa and six had deletions in AZFb. In addition, four patients had both AZFb and AZFc deletions. No deletion in the AZF region was found in the 40 fertile controls.

CONCLUSIONThere is a high prevalence of Y chromosomal microdeletions in Chinese infertile males with azoospermia or oligozoospermia. The MASA technology, which has been established in the present study, provides a sensitive and high-throughput method for detecting the deletion of the Y chromosome. And the results suggest that genetic screening should be advised to infertile men before starting assisted reproductive treatments.

OBJECTIVETo prove analgesia and sedative effect of adjuvant anesthesia with magnetic auricular point-sticking on abdominal gynecological operation and its effect on postoperative recovery of body function.

METHODSNinety-two patients with abdominal gynecological operation were randomly divided into 3 groups. The auricular point-sticking group (APS group, n=31) was pasted and pressed by plasters with magnetic beads at bilateral Shenmen, Pizhixia (subcortex), Zigong (uterus) and Penqiang (pelvic cavity), etc. the night before operation. The placebo group (n=31) was pasted by plasters without magnetic beads. The blank group (n=30) was given no intervention. The mental and gastrointestinal functional changes before and 3 days after the operation were observed.

RESULTSAs compared with those in the control group and the blank group, the postoperative score of Self rating Anxiety Scale (SAS) was less (25.5 +/- 0.81 vs. 28.9 +/- 3.19, 28.3 +/- 2.36, both P < 0.01), with lower-dose of Innovar [(2.5 + 1.1) mL vs. (3.4 + 1.8) mL, (3.2 + 1.6) mL, both P < 0.05], earlier exsufflation after the operation [(34.2 + 12.1) h vs. (46.3 + 10.9) h, (43.2 + 14.8) h, both P < 0.01] and higher level serum of beta-endorphin before and after the operation in the APS group (all P < 0.05).

CONCLUSIONThe magnetic auricular point-sticking has sedative, analgesic and function-regulating effects on the abdominal gynecological operation.
