OBJECTIVETo study the predicting effect of proly 4-hydroxylase beta polypeptide (P4HB) in treating non-small cell lung cancer (NSCLC) patients by Yiqi Chutan Recipe (YCR).

METHODSTotally 46 stage III and IV NSCLC patients were treated by YCR for 4 therapeutic courses. Effect was assessed by RECIST of solid tumor. P4HB expression was detected in the lung cancer tissue by immunohistochemical assay. Factors affecting disease control rates (DCR) of YCR were analyzed by Logistic regression analysis. The correlation between P4HB expression and the effect of YCR was analyzed.

RESULTSThe DCR of advanced NSCLC treated by YCR was 36.96% (17/46 cases). P4HB was high expressed in advanced lung cancer tissue (6/15 cases). Gender, initial treatment, and retreatment are independent factors for affecting DCR of treating lung cancer by YCR.

CONCLUSIONP4HB might be taken as a factor for predicting the effect of YCR in treating NSCLC.

OBJECTIVETo explore the anesthetic effect of preemptive analgesia of frequency acupoint electrical stimulation on painless-induced abortion as well as its effect on anesthetics dosage.

METHODSNinety cases of early pregnancy who selected painless-induced abortion were randomly divided into two groups, 45 cases in each group. Frequency acupoint electrical stimulation at Ciliao (BL 32) and Shenshu (BL 23), disperse-densewave, 2 Hz/100 Hz in frequency for 15 to 20 min, was applied in the group A, which was followed by intravenous anesthesia of propofol. The intravenous anesthesia of propofol was applied in the group B. The blood pressure (BP), heart rate (HR) and SpO2 before, during and after surgery, anesthetic effect and dosage, waking time and adverse events were observed in the two groups.

RESULTSThe BP and HR during and after the surgery in the group A were not statistically different from those before the surgery (all P > 0.05). The BP was reduced and HR was slowed down during the surgery in the group B, which was significantly different from those before the surgery as well as those in the group A (all P < 0.05). The dosage of propofol was (114. 3-+6. 1) mg in the group A. obviously less than (193.2 +/- 8.9) mg in the group B (P < 0.05). The waking time was (5.6 +/- 1.2) min in the group A, obviously less than (10.1 +/- 3.9) min in the group B (P < 0.05). As for anesthetic effect, the incidence of Grade I in the group A was more than the group B (P < 0.05). The adverse events, including nausea, vomiting and contractions pain in the group A were evidently less than those in the group B (all P < 0.05).

CONCLUSIONThe preemptive analgesia of frequency acupoint electrical stimulation could significantly improve anesthetic effect of painless-induced abortion, reduce dosage of anesthetics, shorten waking time of surgery and guarantee the safety of surgery.

OBJECTIVETo observe the short-term clinical effectiveness of bone ring graft technique and to summarize the key points of related surgical operation to provide comprehensive clinical guidelines.

METHODSFifteen patients with severe alveolar bone absorption were selected to receive bone ring grafting and immediate dental implant. Final fixed prostheses were cemented five months after initial implantation. Cone beam CT scans were conducted on all subjects before the procedure, as well as four months post-operation to evaluate alveolar bone height and level of bone height and absorption around the implants. Four to six months after prosthesis installation, each implant's Jemt classification, gingiva attachment, and probing depth (PD) were analyzed. The difference of PD between implants and adjacent teeth, as well as the difference of the bone absorption between labial and lingual sides, was compared. The survival rate of the bone ring and the retention rate of implants were calculated. Complications and patient satisfaction were also investigated.

RESULTSBone graft survival rate was 94.4% and dental implantation retention rate was 100% four months post-operation. Average bone level increase was (6.06 +/- 1.06) mm, average bone absorption was (1.33 +/- 0.84) mm, and average bone thickness at the neck of the dental implant body was (6.94 +/- 0.73) mm. Approximately 4 to 6 months after crown restoration, average bone level increase was (5.62 +/- 1.03) mm, average bone absorption was (1.51 +/- 1.02) mm, and average bone thickness at the neck of the dental implant body was (6.77 +/- 0.72) mm. The PD around the implant body and the adjacent teeth was statistically insignificant. No major post-operative complication was observed, restorations were successful, and patient satisfaction level was high.

CONCLUSIONBone ring graft technique and immediate dental implantation are relatively simple to perform, and these techniques facilitate reduction in required treatment time. Short-term effect is reliable and satisfactory, whereas long-term outcomes require further follow up and study.

Objective To compare the efficacy of continuous ambulatory peritoneal dialysis (CAPD) and hemodialysis (HD) on polycystic kidney disease (PKD) patients with end-stage renal disease (ESRD). Methods Retrospective analysis was made on 29 patients with PKD who carded out dialysis therapy for over 3 months in our department from January 2001 to December 2007. They were divided into the CAPD group (10 cases, 34.5%) and HD group (19 cases, 65.5%). Ten cases of non-PKD CAPD patients were randomly selected as the control, who matched the CAPD group in terms of age and gender. The patient information was recorded, such as general data, initial dialysis data, comphcations, survival time, quit of dialysis or death, etc. Kaplan-Meier method and Log-rank test were adopted to analyze the survival rate. Results The survival rates of 1-, 3- and 5-year for the CAPD group were 90%, 75% and 25% respectively, while for the HD group were 94.4%, 67.6%, and 48.3%, and for the control were 83.3%, 44.4% and 22.2% respectively, with no significant differences among 3 groups (P>0.05). group and the control were quite similar. The incidence of peritonitis for the CAPD group (0.62 times/patient year) was similar to that for the control (0.30 times/patient year)(P>0.05). The duration of the lust peritonitis[(23.5±4.0) months vs (20.0±15.8) months] and the catheter exit-site infection (0 time vs 1 time) for two groups were similar as well (P>0.05). One patient had hernia in CAPD group and no patient in control group had hernia. The incidence of peritoneal dialysate leakage was similar between these two groups. In the HD group, two patients (10.5%) had cerebral hemorrhage resulting in death, and 10 patients (52.6%) had cystic hemorrhage, 5 out of whom underwent operation due to repeated cystic hemorrhage and 2 cases received unilateral nephrectomy because of severe hemorrhage. No patient in CAPD group had cerebral hemorrhage but 1 patient (10%) had cystic hemorrhage and recovered after conservative treatment. The hemorrhage complication incidence of CAPD group was significantly lower than that of HD group (P<0.05). Conclusions The prognosis and complication incidence in PKD and non-PKD patients treated with CAPD are similar. The prognosis of PKD patients treated with CAPD or HD is also similar, and the risk of hemorrhage complications of PKD patients treated with CAPD may be decreased compared with those treated with HD. PKD patients can choose HD or PD as the initial therapy of ESRD unless existence of hernia or intolerance. PKD is not the contraindication of PD.

OBJECTIVETo observe the feasibility of measuring multiple circulating cytokines by protein chips in patients with acute coronary syndrome (ACS).

METHODSCirculating cytokines were determined by protein chips in 50 control cases and 104 ACS cases of unstable angina pectoris (UA, n = 50) and acute myocardial infarction (AMI, n = 54) cases.

RESULTSThe levels of serum MMP-9, sCD40L, CRP, IL-6, H-FABP, cTnI and plasma IL-8, NT-proBNP, sVCAM-1, ET-1 in ACS group were significantly higher than those in the control group (all P < 0.01). Serum H-FABP and cTnI were significantly higher in AMI patients than in UA patients (P < 0.01). Serum MMP-9, sCD40L, CRP, IL-6 and plasma sVCAM-1, ET-1 tended to be higher in AMI patients as compared to UA patients (all P > 0.05). Serum MMP-9, sCD40L, and H-FABP were positively correlated with the severity of angina(r = 0.653, r = 0.745, r = 0.933, P < 0.01, respectively). Serum MMP-9, sCD40L, and H-FABP increased in proportion to the levels of Braunwald angina classes in UA patients (angina class I < angina class II < angina class III, P < 0.01).

CONCLUSIONSCirculating cytokines were significantly increased in ACS patients and positively correlated to Braunwald angina classes in UA patients.

OBJECTIVETo understand the clinical characteristics of hypoxic-ischemic encephalopathy (HIE) in full-term infants and to explore the value of magnetic resonance imaging (MRI) for the early prediction of HIE prognosis.

METHODSThe medical data, including histories, clinical manifestations, MRI findings and follow-up outcomes, of 348 full-term infants with HIE between January 2001 and December 2005 were retrospectively reviewed.

RESULTSHIE patients (348 cases) accounted for 8.25% of in-patients (4220 cases) over the five years. The etiology of HIE mainly attributed to birth asphyxia (76.2%), consisting of mild asphyxia (59.2%) and severe asphyxia (40.8%). A poor outcome was confirmed in 10.1% of these patients, including 27.3% in severe HIE, 10.0% in moderate HIE and 1.5% in mild HIE cases. All of patients whose MRI showed diffusion intraparenchymal hemorrhages and cerebral infarctions had poor outcomes. Fourteen (87.5%) out of the 16 cases with basal ganglia and thalamic or internal capsule injury and 9 (81.8%) out of the 11 cases with cytotoxic brain edema diagnosed by diffusion weighted imaging had poor outcomes.

CONCLUSIONSHIE is one of common diseases in newborn infants. The etiology of neonatal HIE mainly attributed to birth asphyxia, mild asphyxia accounting for a greater proportion. MRI findings can be helpful for the early prediction of HIE prognosis.

BACKGROUNDElevation of intraocular pressure is usually associated with primary open angle glaucoma and caused by increased outflow resistance. A two-color fluorescent tracer technique was developed to investigate the hydrodynamics of aqueous humor outflow with changing intraocular pressure within the same eye, to better understand the relationship between outflow facility and effective filtration area.

METHODSEighteen enucleated bovine eyes were first perfused at 30 mmHg with Dulbecco's phosphate-buffered saline containing 5.5 mmol/L D-glucose. After a stable baseline facility, red fluorescent microspheres (0.5 microm, 0.002% v/v) were exchanged and perfused. Eyes in the one-color control group (n = 6) were immediately perfused with fixative. In the experimental group (n = 6), eyes were perfused with green tracer after intraocular pressure reduced to 7 mmHg, while in the two-color control group (n = 6), eyes were perfused with green tracer with intraocular pressure remaining at 30 mmHg. All 12 eyes were then perfusion-fixed. Outflow facility was continuously recorded in all eyes. Confocal images were taken along the inner wall of the aqueous plexus and the percent of the effective filtration length (PEFL; length of inner wall exhibiting tracer labeling/total length of inner wall) was measured. The relationships between outflow facility and PEFL were analyzed statistically.

RESULTSNo significant differences were found in baseline facilities (microl x min(-1) x mmHg(-1)) among the three groups (the experimental group: 0.93 +/- 0.12; the two-color control group: 0.90 +/- 0.19; the one-color control group: 0.98 +/- 0.13). In the experimental group, the outflow facility was significantly higher at 7 mmHg (4.29 +/- 1.01) than that at 30 mmHg (1.90 +/- 0.67, P < 0.001), which corresponded to a significant increase in the PEFL at 7 mmHg (54.70 +/- 8.42) from that at 30 mmHg ((11.76 +/- 4.56)%, P < 0.001). The PEFL labeled by red fluorescent microspheres in the experimental group ((11.76 +/- 4.56)%) showed no significant difference from that of the one-color control group ((13.39 +/- 2.19)%, P = 0.473) or the two-color control group ((11.49 +/- 4.95)%, P = 0.930). The PEFL labeled by green fluorescent microspheres in the experimental group ((54.70 +/- 8.42)%) was significantly higher than that of the two color control group ((37.34 +/- 8.17)%, P = 0.010). A positive correlation was found between outflow facility and PEFL (r = 0.897, R(2) = 0.804) in the experimental group.

CONCLUSIONSChanges in aqueous humor outflow patterns before and after a change in intraocular pressure can be successfully distinguished within the same eye using our newly developed two-color tracer perfusion technique. The PEFL showed positive correlation with the outflow facility.
