AIM: To analyze the results of phacovitrectomy with internal limiting membrane(ILM) peeling to treat foveoschisis in ultra-high myopia.METHODS: Totally 32 eyes of 32 ultra-high myopia patients with foveoschisis were selected retrospectively.The preoperative refractive errors ranged from-12.00D to-20.00D with the mean of-15.78±2.16D.The best corrected visiual acuity(BCVA) were converted to LogMAR acuity, and the average BCVA was 4.1±0.4.Conventional phacovitrectomy with ILM peeling by ICG dying were performed.Gas tamponade were performed to end the operation.The BCVA and the foveoschisis cavity were observed by 1-9mo after the surgery, with the mean of 4.5mo.RESULTS: The foveoschisis cavity of 30 eyes were healed with BCVA increased and visual distortion alleviated distinctly (94%)(t=-7.91, P<0.05).CONCLUSION: Phacovitrectomy with ILM peeling is useful in treating foveoschisis in ultra-high myopia with visual function preserving.

OBJECTIVETo evaluate the outcomes of T3a prostate cancer with unfavorable prognostic factors treated with permanent interstitial brachytherapy combined with external radiotherapy and hormone therapy.

METHODSFrom January 2003 to December 2008, 38 patients classified as T3a prostate cancer with unfavorable prognostic factors were treated with trimodality therapy (brachytherapy + external radiotherapy + hormone therapy). The prescription dose of brachytherapy and external radiotherapy were 110 Gy and 45 Gy, respectively. The duration of hormone therapy was 2-3 years. The endpoints of this study included biochemical failure-free survival (BFFS), distant metastasis-free survival (DMFS), cancer-specific survival (CSS), and overall survival (OS). Survival curves were calculated using the Kaplan-Meier method. The Log-rank test was used to identify the prognostic predictors for univariate analysis.

RESULTSThe median follow-up was 71 months. The serum pre-treatment prostate-specific antigen (PSA) level ranged from 10.0 to 99.8 ng/ml (mean 56.3 ng/ml), the Gleason score ranged from 5 to 9 (median 8), and the percentage of positive biopsy cores ranged from 10% to 100% (mean 65%). The 5-year BFFS, DMFS, CSS, and OS rates were 44%, 69%, 82%, and 76%, respectively. All biochemical failures occurred within 40 months. The percentage of positive biopsy cores was significantly correlated with BFFS, DMFS, and OS (all P=0.000), and the Gleason score with DMFS (P=0.000) and OS (P=0.001).

CONCLUSIONST3a prostate cancer with unfavorable prognostic factors presents not so optimistic outcome. Hormone therapy should be applied to prolong the biochemical progression-free or metastasis-free survival. The percentage of positive biopsy cores and the Gleason score are significant prognostic factors.

OBJECTIVETo observe clinical effect of integrated Chinese medical (CM) treatment (as maintenance therapy) on the progression-free survival (PFS) and overall survival (OS) in patients with advanced non-small-cell lung cancer (NSCLC) after first-line chemotherapy.

METHODSThe study was a prospective, randomized, controlled clinical trial. Totally 69 non-progressive advanced NSCLC patients treated with first-line chemotherapy were randomly assigned to the test group (34 cases) and the control group (35 cases). Patients in the control group were treated with one Western drug chemotherapy (Gemcitabine or Alimta or docetaxel). Those in the test group were treated with integrated CM treatment (CM decoction, CM Intravenous preparation, and point application). Each cycle consisted of 21 days. Treatment lasted till the disease progressed, or intolerable toxic/adverse reactions occurred, or patients refused to continue the treatment. Patients' life spans were regularly followed-up.

RESULTS(1) The median cycle of maintenance therapy was 2 cycles for two groups with no statistical difference (P =0.274). The median PFS was 12.43 weeks in the test group and 10.00 weeks in the control group, showing statistical difference (P =0.025). The middle survival time (MST) was 18.8 months in the test group and 16.73 months in the control group, showing no statistical difference (P =0.437).

CONCLUSIONCM treatment (as maintenance therapy) showed quail effect to one Western drug chemotherapy in prolonging patients' life span.

OBJECTIVE: To explore the application value of postmortem multi-slice spiral computed tomography (MSCT) by observing and analyzing the injury features in the traffic accident victims. METHODS: Ten traffic accident victims were scanned with whole body MSCT. The systemic autopsy was subsequently performed to compare with the results of MSCT. The advantages and disadvantages of autopsy and MSCT for obtaining the information of traffic accident injuries were then analyzed. RESULTS: MSCT could reveal 3D shape of fractures clearly and detect air accumulation in different positions of the body, which showed the obvious advantages compared with autopsy. However, the resolution of MSCT was limited compared to the detection of organ and soft tissue injuries. CONCLUSION A combination of MSCT and autopsy is the best way for determining the manner and the cause of death in traffic fatality victims.

To study the effect of steaming and baking process on contents of alkaloids in Aconite Lateralis Radix (Fuzi), 13 alkaloids were analyzed by UPLC-MS/MS equipped with ESI ion source in MRM mode. In steaming process, the contents of diester-diterpenoid alkaloids decreased rapidly, the contents of monoester-diterpenoid alkaloids firstly increased, reached the peak at 40 min, and then deceased gradually. The contents of aconine alkaloids (mesaconine, aconine and hypaconine) increased all the time during processing, while the contents of fuziline, songorine, karacoline, salsolionl were stable or slightly decreased. In baking process, dynamic variations of alkaloids were different from that in the steaming process. Diester-diterpenoid alkaloids were degraded slightly slower than in steaming process. Monoester-diterpenoid alkaloids, aconine alkaloids and the total alkaloids had been destroyed at different degrees, their contents were significantly lower than the ones in steaming Fuzi at the same processing time. This experiment revealed the dynamic variations of alkaloids in the course of steaming and baking. Two processing methods which can both effectively remove the toxic ingredients and retain the active ingredients are simple and controllable, and are valuable for popularization and application.

Objective To investigate expressions of surface maturation markers, secreting cytokines and the stimulat?ing effect on T lymphocytes in the dendritic cells (DC) from peripheral blood of tuberculosis (TB) patients after loading dose treatment. Methods TB patients who received initial treatment (n=68) were collected at the fifth hospital of Shijiazhuang from 2013 June to 2014 January. Base on clinical diagnosis and treatment guidelines of tuberculosis, they were divided into sputum smear-negative group (35 cases) and sputum smear-positive group(33 cases). Forty cases of healthy adult were se?lected as control group. Mononuclear cells were isolated from peripheral blood and were cultured in medium to differentiate into DCs. Expression levels of CD83 and CD86 on DCs were examined by flow cytometry. The proliferation of allogeneic mixed lymphocyte stimulated by DCs was dectected using MTT assay. Contents of IL-12, IL-10 and INF-γin the cultural supernatant of DCs and blood serum from TB patients were detected by ELISA. Results Compared with controls ,the ex?pressions of CD83 and CD86 on DCs in TB patients after loading dose treatment decreased obviously(P<0.05), and the ability to stimulate the proliferation of lymphocytes reduced evidently(P<0.05). What’s more, IL-12 level increased mark?edly(P<0.05)while IL-10 and INF-γlevels presented no significant difference among the three groups (P>0.05). Conclu?sion The expressions of maturation markers of DC cells of the peripheral blood in TB patients after initial treatment de?creased. The ability of stimulating mixed lymphocyte proliferation is also significantly reduced while secretion of IL-12 was enhanced.

Objective To investigate the regional left ventricular function after mitral valve replacement with and without chordal preservation by strain rate imaging. Methods A total of 55 patients undergoing mitral valve replacement were enrolled. Twenty underwent complete excision of the subvalvular apparatus (group A), 20 preserved the posterior chordopapillary apparatus only (group B) and the other 15 underwent total chordal preservation (group C). Systolic peak strain rate (SRs) were measured preoperatively, at 7-10 days and 3 months after operation. Results Before operation, SRs had no differences between different segments of the left ventricular in each group (F=0.37, 0.74, 0.90, all P>0.05). At 7-10 days after operation, SRs in the most segments of left ventricular were signiifcantly lower than those of before operation (F=3.91, 8.12, 7.57, all P<0.05). At 3 months after operation, SRs in some segments of left ventricular were signiifcantly higher than those of preoperation in each group (t=2.12, 3.19, 3.25, 2.08, 2.78, 4.79, 2.81, 2.58, 2.87, 1.60, 0.34, 1.04, 0.73, 0.70, 1.68, all P<0.05). SRs had no signiifcant differences between each segment of left ventricular in group C (F=1.76, P>0.05). By contrast, SRs in some segments of left ventricular were different from those of other segments in group A and group B (F=17.8, 8.52, both P<0.05). Conclusion Comparing to conventional mitral valve replacement and mitral valve replacement with preservation of posterior subvalvular apparatus, mitral valve replacement with preservation of total subvalvular apparatus makes the papiltary function preserved completely, which are beneifcial for the motor coordination of left ventricular wall and the recovery of regional left ventricular function.
