OBJECTIVETo explore the effect of acupuncture-anesthetic composite anesthesia (AACA) on the incidence of postoperative cognitive dysfunction (POCD) and changes of TNF-alpha, IL-1beta, and IL-6 in elderly patients.

METHODSTotally 83 patients undergoing surgical resection of gastrointestinal tumor were randomly assigned to the simple anesthesia group (A group, 41 cases) and the AACA group (B group, 42 cases). Patients in Group A received endotracheal general anesthesia. Those in Group B were induced by acupuncture anesthesia for 30 min by needling at Baihui (DU20), Neiguan (PC6), Zusanli (ST36). The electro-acupuncture (EA) apparatus was connected after arrival of qi, with the wave pattern of density 2/100 Hz. The stimulus intensity was set by patients' tolerance, with the peak current of 5 mA. Then the endotracheal general anesthesia was performed and the EA lasted till the end of the surgery. The cognitive function of all patients was assessed before operation and at day 3 after operation using mini-mental state examination (MMSE). POCD was confirmed if with one or more decreased stand- ard. The peripheral venous blood was collected before anesthesia induction (TO), immediately at the end of surgery (T1), 24 h after operation (T2), and 48 h after operation (T3), and serum concentrations of IL-1beta, IL-6, and TNF-alpha were correspondingly measured using ELISA.

RESULTSThe postoperative anesthesia awakening time was shorter in Group B than in Group A [(20.37 +/- 6.09) min vs (29.24 +/- 7.48) min, P < 0.05]. The remifentanil dose used during the operation was less in Group B than in Group A (P < 0.05). The incidence of POCD at day 3 was lower in Group B than in Group A [10/41 (23.8%) vs 15/42 (36.5%), P < 0.05]. The concentrations of IL-1beta, IL-6, and TNF-alpha at T1-T3 were higher than those at TO in the two groups (P < 0.05). The increment of TNF-alpha and IL-1beta was less in Group B than in Group A (P < 0.05). CONCLUSION AACA could reduce the incidence of POCD and inhibit postoperative release of TNF-alpha, IL-1beta, and IL-6 in elderly patients undergoing colorectal cancer resection.

OBJECTIVETo observe the impacts of different frequencies of electroacupuncture (EA) on post-operative cognitive function and the change in serum S-100beta protein under the compound anesthesia of acupuncture and drugs.

METHODSOne hundred and twenty-four patients of abdominal operation at selective time were randomized into a routine drug anesthesia group (group A, 24 cases), a meridian point 2 Hz group (group B, 26 cases), a me ridian point 2 Hz/100 Hz group (group C, 25 cases), a meridian point 100 Hz group (group D, 24 cases) and a transcutaneous acupoint electric stimulation 2 Hz/100 Hz group (group E, 25 cases). In group A, the endotrachea-lgeneral anesthesia was applied. In the rest groups, the acupuncture anesthesia was induced for 30 min before the endotracheal general anesthesia, at Baihui (GV 20), Yintang (GV 29) and Neiguan (PC 6), with G6805-2 electric acupuncture apparatus used. In group B, the continuous wave and 2Hz in frequency were selected. In group C, the disperse-dense wave and 2 Hz/100 Hz in frequency were selected. In group D, the continuous wave and 100 Hz in frequency were selected. In group E, the disperse-dense wave and 2 Hz/100 Hz in frequency were selected, and the electrode pads were stick on the acupoints and connected with the electric stimulation till the end of operation. Mini-mental state examination (MMSE) was adopted to evaluate and record the changes in cognitive function 1 day before operation and on the 3rd day after operation. The conditions of post-operative cognitive dysfunction (POCD) in the patients and the changes in serum S-100beta protein were monitored before and at the end of operation.

RESULTSThe incidence rate of POCD on the 3rd day after operation was 41.7% (10/24) in group A. The incidence rates of POCD were 26.9% (7/26), 16.0% (4/25), 33.3% (8/24) and 16.0% (4/25) in group B, C, D and E separately. Compared with group A, the incidence rate of PCOD in group B, C, D and E were reduced (all P<0.05), the incidence rate in group C and E were lower than that in groups B and D (all P<0.05). At the end of operation, the level of serumS-100beta protein was (0.186 +/- 0.027) microg/L in group A, the levels were (0.165 +/- 0. 028) microg/L, (0.166 +/- 0.027) microg/L, (0.163 +/- 0.025) microg/L and (0.164 +/- 0.025) microg/L in group B, C, D and E separately. The levels of serum S-100beta protein in group B, C, D and E were lower than that in group A separately (all P<0.05).

CONCLUSIONThe general anesthesia assisted with EA at different frequencies reduces the incidence of cognitive dysfunctionand, decreases the level of serum S-100beta protein after intestinal cancer resection. The effects of the meridian point electric stimulation at 2 Hz/100 Hz and the transcutaneous electric stimulation at 2 Hz/100 Hz are the best. Hence, these two approaches of anesthesia deserve to be recommended practically.

Objective To observe whether the expression of interferon-regulatory factor genes are re- lated to systemic lupus erythematosus (SLE).Methods The clinical data of 45 SLE patients and 37 normal controls were collected.Total RNA of peripheral blood was extracted and transcripted into cDNA.Sybr green dye based real-time quantitative PCR method was used to compare the expression (indicated as-??Ct value) of IRFI,IRF4,IRF8 in patients with SLE and those in the controls.Results The levels of IRF1,IRF4 and IRF8 mRNA were-3.90?0.19,-8.04?0.25 and 3.60?0.15 respectively in normal controls.In SLE patients, IRF4 mRNA expression was -8.82?0.18,higher than that in normal (P=0.011).But IRF8 mRNA expression was 3.09?0.13,lower than that in normal (P=0.012).Conclusion Abnormal IRF mRNA expression is found in the peripheral blood of SLE patients.IRFs may play roles in the pathogenesis of SLE by affecting the differen- tiation of Th cells.

OBJECTIVETo investigate the expressions of telomerase reverse transcriptase (TRT) and vascular endothelial growth factor (VEGF) and their correlation in prostate cancer (PCa).

METHODSTRT and VEGF expressions were assayed in 30 cases of PCa and 30 cases of benign prostatic hyperplasia (BPH) by means of immunohistochemistry (SP) combined with computer assisted image analysis.

RESULTSThe expression of TRT was detected in 19 of the 30 cases of PCa and 5 of 30 cases of BPH, and that of VEGF in 23 of the 30 PCa and 14 of the 30 BPH patients. TRT and VEGF expressions were significantly higher in cancer tissues than in BPH (P < 0.05). A significant correlation was observed between TRT and VEGF expressions (r = 0.8333, P < 0.05).

CONCLUSIONThe expression of TRT or VEGF might be a malignant phenotype in PCa. The expression of TRT is significantly correlated with that of VEGF, but the mechanisms are yet to be further studied.

BACKGROUND: Posterior internal fixation is one of the most common methods for thoracolumbar fractures. There is a lack of systematic evaluation about the efficacy of injured vertebra pedicle screw fixation(IVPSF)versus short-segment pedicle instrumentation (SSPI) for thoracolumbar fracture. OBJECTIVE: To compare the clinical outcomes of IVPSF and SSPI for single thoracolumbar fracture through a METHODS: A computer-based on-line research of PubMed, Medline, Embase, Cochrane Library, CNKI, and WanFang databases was performed for the studies regarding IVPSF versus SSPI for thoracolumbar fracture from 1990 to 2016. meta-analysis. The randomized controlled trials and cohort studies were collected based on the strict criteria of inclusion and exclusion. A meta-analysis was conducted on Revman5.3 sofeware. RESULTS AND CONCLUSION: (1) Eleven articles were enrolled, including 5 English and 6 Chinese ones, involving 689 patients (328 cases for IVPSF and 361 cases for SSPI). (2) The meta-analysis indicated that the operation time, blood loss and mean hospital stay showed no significant differences between two groups. IVPSF showed more effective than SSPI in the kyphotic angle correction and anterior vertebral height recovery at postoperation and 1-5 years of follow-up. Moreover, the incidence of postoperative fixation failure in IVPSF was lower than that in SSPI. (3) These findings suggest that IVPSF that reduces the postoperative fixation failure rate for thoracolumbar fractures provides better kyphosis correction and restoration of anterior vertebral height at post-operation and 1-5 years of follow-up.

OBJECTIVEThe aim of this study is to investigate the changes of hard tissue profile in anterior-posterior and vertical direction in bimaxillary protrusion patients after orthodontic treatment.

METHODSA total of 24 bimaxillary protrusion patients (male 8, female 16), aged from 11.2 to 29.0 (average 16.9 years old), were selected to be treated with standard edgewise technique consisted of 4 first premolars extraction. Cephalometrics were taken before and after treatment. The changes of hard tissue profile were studied using the computer-aid X-ray cephalometric analysis.

RESULTS1. The length of the maxillary and the mandible increased significantly, but the anterior-posterior relationship of the maxillary and the mandible did not change significantly. 2. The anterior and posterior facial height increased significantly, but the ratio of anterior and posterior facial height and the angle of MP-FH which reflected the inclination of the mandible plane did not change significantly. 3. The height of the upper and lower first molar increased significantly along with the increase of the anterior and posterior facial height. 4. The height of the upper incisors increased significantly, but the height of the lower incisors decreased significantly.

CONCLUSIONThe anchorage in anterior-posterior and vertical direction were controlled preferably, the patients did not manifest disadvantageous vertical growth trend.

To evaluate the adjuvant effect of recombinant enterovirus 71 (EV71) subunit vaccine formulated with chitosan, rabbits were orally immunized with recombinant VP1 (rVP1) or rVP1 mixed with chitosan adjuvant. Levels of virus-specific IgG and IgA antibodies in sera, mucosal wash buffer (intestine, nasal cavity, and lung), and feces were determined by indirect enzyme-linked immunosorbent assay (ELISA). The titers of neutralizing antibodies against EV71 were determined using cytopathic effect-based neutralizing assay, and levels of cytokines (IFN-gamma and IL-4) secreted from in vitro-cultured rabbit splenic lymphocytes under antigen stimulation were also determined by ELISA. Results showed that immunization with rVP1 alone could only induce low levels of serum IgG and mucosal IgA, while rVP1 combined with chitosan adjuvant were able to induce significantly higher levels of antibodies, rVP1 can only induce neutralizing antibodies when used in combination with chitosan. Levels of IFN-gamma and IL-4 in the group immunized with rVP1 plus chitosan were significantly higher than those in the group immunized with rVP1 only or those in the control groups. Our study lays the foundation for development of oral VP1 vaccine against EV71 infection.

Objective To validate the value of age-adjusted D-dimer combined with clinical probability to confirm or exclude deep vein thrombosis (DVT) in elderly patients.Method Elderly patients (≥65 years) suspected with DVT were evaluated by Wells score and D-dimer test.All patients underwent ultrasonography examination except for patients with Wells score ＜ 2 and negative D-dimer test results.Conventional cut-off value is 500 μg/L,while age-adjusted cut-off value is set as patient's age × 10 μg/L.We compared the sensitivity and specificity using the 2 cut-off values in confirming or excluding the diagnoses of DVT.Results The study population consisted of 624 patients [mean age (76.4 ± 19.3) years],DVT was confirmed in 192 (30.8％) patients.Using Wells score model,326 patients(52.2％) were scored as unlikely DVT and DVT was confirmed by ultrasonography in 44 patients (13.5％),and 298 patients as likely DVT patients and DVT was confirmed in 148 patients (55.0％).The sensitivity,specificity,positive predictive value,and negative predictive value by conventional and age-adjusted D-dimer cut-off value for diagnosing DVT in low-risk patients evaluated by Wells score model were 95.5％,40.4％,20.0％,98.3％ and 95.5％,61.0％,27.6％,87.1％,respectively,and which were 89.9％,67.3％,73.1％,87.1％ and 89.2％,89.3％,89.2％,89.3/％,respectively,in high-risk patients evaluated by Wells score model.Thus,specificity increased about 20％ using age-adjusted D-dimer cut-off value compared with conventional D-dimer cut-off value.Conclusion The age-adjusted D-dimer cut-off value combined with clinical probability evaluation could increase diagnosing specificity of DVT in elderly patients.

OBJECTIVETo research the efficacy,security and necessity of combined therapy for preventing postsurgery stiffness after elbow fracture.

METHODSFrom May 2009 to April 2010, 60 patients with elbow fractures treated by operation were randomly divided into two groups: combined therapy group and past procedure group. Thirty patients in the combined therapy group,including 12 males and 18 females, ranging in age from 23 to 63 years, averaged (43.53 +/- 7.74) years old; 15 patients had two parts fractures, including humeral intercondylar fractures combined with olecroanon and (or) ulna coronoid process fractures in 8 cases, fractures of exterior and interior humeral condyle combined with capitulum radius in 3 cases, fractures of olecroanon and ulna coronoid process in 3 cases, fractures of olecroanon and capitulum radius in 1 case; other 15 patients had one part fractures, including fractures of exterior or interior humeral condyle in 8 cases,fractures of olecroanon or ulna coronoid process in 6 cases, fractures of capitulum radius in 1 patient. Thirty patients in the past procedure group,including 11 males and 19 females, ranging in age from 24 to 67 years, averaged (46.13 +/- 6.22) years; 15 patients had two parts fractures, including fractures of humeral intercondylar fracture combined with olecroanon and(or) ulna coronoid process in 7 cases, fractures of exterior and interior humeral condyle combined with capitulum radius in 2 cases,fractures of olecroanon and ulna coronoid process in 5 cases,fractures of humeral intercondylar fracture combined with capitulum radius in 1 patient; 15 pa- tients had one part fracture, including fractures of exterior or interior humeral condyle in 6 cases, fractures of olecroanon or ulna coronoid process in 8 cases, fractures of capitulum radius in 1 patient; the patients in the past procedure group were treated with past procedure methods. Mayo Elbow Performance Score (including gmotion of elbow joint) and security (using X-ray to recheck displacement fracture, internal fixation failure and heterotopic ossification) were evaluated at postoperative 6 months. From 2002 to 2006, 30 patients were reviewed as historical control group, including 17 males and 13 females, ranging in age from 27 to 62 years, averaged (47.17 +/- 7.83) years; 15 patients had two parts fractures, including fractures of humeral intercondylar combined with olecroanon and(or) ulna coronoid process in 7 cases, fractures of exterior and interior humeral condyle combined with capitulum radius in 1 case, fractures of olecroanon and ulna coronoid process in 6 cases, fractures of ulna coronoid process and capitulum radius in 1 case; 15 patients had one part fractures,including fractures of exterior or interior humeral condyle in 9 cases, fractures of olecroanon or ulna coronoid process in 5 cases,fractures of capitulum radius in 1 case. The Mayo Elbow Performance Score of the patients in historical control group was evaluated retrospectively at postoperative 6 months and the results were compared with that of past procedure group.

RESULTSMayo score of combined therapy group was (91.00 +/- 7.81)surpassed to (76.83 +/- 10.71) of the past procedure group and (73.17 +/- 1.99) of historical control group (F = 24.98, P < 0.05). The range of motion of elbow was (102.40 +/- 9.16) degrees of combined therapy group surpassed to (83.57 +/- 6.21) degrees of the past procedure group (t = 9.325, P < 0.05). There were no internal fixation loose,obvious fracture displacement and heterotopic ossification in each X-ray examination of patients in the combined therapy group. The Mayo score of historical control group was (73.17 +/- 11.99), showing no significant differences when compared with (76.83 +/- 10.71) of the past procedure group (LSD, P = 0.172).

CONCLUSIONCombined therapy including different stage, different method combination and different subject to practice to prevent postsurgery stiffness after elbow fracture is effect, security and necessity.
