ABSTRACT

OBJECTIVE@#To investigate the clinical effects of dual mobility total hip prosthesis in treating femoral neck fracture patients with hemiplegia.@*METHODS@#A retrospective analysis was performed on 18 patients with femoral neck fracture combined with hemiplegia who underwent dual mobility total hip prosthesis replacement from March 2014 to December 2016. The follow up data of these patients was complete. There were 5 males and 13 females, aged 65 to 70 years old with an average of (66.50±1.38) years. The left side was involved in 12 cases, while the right side in 6 cases. There were 4 cases with Garden Ⅲ type and 14 cases with type Ⅳ. Limb muscle strength of hemiplegia were in grade Ⅳ. The posterior-lateral approach of hip joint was used in surgery for all patients. The implant position, dislocation and loosening of the prosthesis were evaluated by X-ray examination. Harris hip score and the Merle D'aubigne score were used to assess the hip function in the follow up.@*RESULTS@#The operation duration was for 70-90 (81.56±7.48) min and the blood loss during the operation was for 160-200 (170.32± 12.56) ml. No blood was transfused during the operation. Postoperative incisions were healed at the first stage. The follow-up time was for 28-60(36.0±3.5) months. Harris hip score increased from 16.94±0.73 preoperatively to 96.19±1.27 at the final follow-up(<0.05). Merle D 'Aubigne score increased from 3.96±0.06 preoperatively to 16.81±0.63 at the final follow-up(< 0.05). No fracture or nerve or vascular injury were found during the operation. The postoperative X-ray showed that the prosthesis was in good position. No complications such as joint dislocation, dislocation of prosthesis, loosening of prosthesis, fracture around the prosthesis, pain in the front of thethigh, fracture of the self tapping screw in the ilium, and delayed infection occurred in the patients after operation.@*CONCLUSION@#Dual mobility total hip prosthesis has the advantages of both good initial stability and low dislocation rate of the prosthesis, and the clinical application of total hip replacement in hemiplegic femoral neck fracture is satisfactory.

ABSTRACT

Synaptic cell adhesion molecules (CAMs) are a type of membrane surface glycoproteins that mediate the structural and functional interactions between pre- and post-synaptic sites. Synaptic CAMs dynamically regulate synaptic activity and plasticity, and their expression and function are modulated by environmental factors. Synaptic CAMs are also important effector molecules of stress response, and mediate the adverse impact of stress on cognition and emotion. In this review, we will summarize the recent progress on the role of synaptic CAMs in stress, and aim to provide insight into the molecular mechanisms and drug development of stress-related disorders.

ABSTRACT

Chronic stress may disrupt the normal neurodevelopmental trajectory of the adolescent brain (especially the prefrontal cortex) and contribute to the pathophysiology of stress-related mental illnesses, but the underlying molecular mechanisms remain unclear. Here, we investigated how synaptic cell adhesion molecules (e.g., nectin3) are involved in the effects of adolescent chronic stress on mouse medial prefrontal cortex (mPFC). Male C57BL/6N mice were subjected to chronic social instability stress from postnatal days 29 to 77. One week later, the mice exposed to chronic stress exhibited impaired social recognition and spatial working memory, simplified dendritic structure, and reduced spine density in the mPFC. Membrane localization of nectin3 was also altered, and was significantly correlated with behavioral performance. Furthermore, knocking down mPFC nectin3 expression by adeno-associated virus in adolescent mice reproduced the stress-induced changes in behavior and mPFC morphology. These results support the hypothesis that nectin3 is a potential mediator of the effects of adolescent chronic stress on prefrontal structural and functional abnormalities.

ABSTRACT

The main lysosomal protease cathepsin D (cathD) is essential for maintaining tissue homeostasis via its degradative function, and its loss leads to ceroid accumulation in the mammalian nervous system, which results in progressive neurodegeneration. Increasing evidence implies non-proteolytic roles of cathD in regulating various biological processes such as apoptosis, cell proliferation, and migration. Along these lines, we here showed that cathD is required for modulating dendritic architecture in the nervous system independent of its traditional degradative function. Upon cathD depletion, class I and class III arborization (da) neurons in Drosophila larvae exhibited aberrant dendritic morphology, including over-branching, aberrant turning, and elongation defects. Re-introduction of wild-type cathD or its proteolytically-inactive mutant dramatically abolished these morphological defects. Moreover, cathD knockdown also led to dendritic defects in the adult mushroom bodies, suggesting that cathD-mediated processes are required in both the peripheral and central nervous systems. Taken together, our results demonstrate a critical role of cathD in shaping dendritic architecture independent of its proteolytic function.

ABSTRACT

Objective:To analyze the cardiopulmonary function of stable patients with pulmonary arterial hypertension (PAH), and to explore effects of the cardiopulmonary exercise testing (CPET)-based individualized moderate-intensity exercise prescription on cardiopulmonary functional reserve and exercise capacity in patients with PAH. Methods:From April, 2018 to July, 2019, 31 stable patients with PAH (PAH group) and 32 healthy counterparts (normal group) were enrolled. All subjects underwent CPET. PAH group was assessed with 6-Minute Walking Test (6MWT), and then was divided into exercise group (n = 16) and control group (n = 15). Both groups were treated with ordinary targeted drugs, while the exercise group was additionally provided with an individualized moderate-intensity exercise prescription of △50% power treadmill training, five days a week for eight weeks. CPET and 6MWT were conducted again after intervention. Results:Before intervention, body mass, body mass index (BMI), force vital capacity (FVC), forced expiratory volume in one second (FEV1), maximum voluntary ventilation (MVV), anaerobic threshold (AT), peak heart rate (HRpeak), peak systolic blood pressure (SBPpeak), peak load power (WRpeak), peak oxygen uptake (VO2peak), peak oxygen pulse (VO2/HRpeak), peak cardiac output (COpeak), peak minute ventilation (VEpeak), peak end-tidal carbon dioxide (PETCO2peak), peak pulse oxygen saturation (SpO2peak) and oxygen uptake efficiency plateau (OUEP) were significantly lower (t > 2.419, P < 0.05), and the rest heart rate (HRrest), peak dead space to tidal volume ratio (VD/VTpeak), minimum ventilatory equivalent for carbon dioxide (Lowest VE/VCO2) and slope of ventilatory equivalent for carbon dioxide (VE/VCO2 slope) were higher (|t| > 2.615, P < 0.05) in PAH group than in the normal group. After intervention, FEV1, MVV, VO2peak (ml/min/kg) and VO2/HRpeak decreased in the control group (t > 2.272, P < 0.05); FVC, FEV1, MVV, AT, SBPpeak, WRpeak, VO2peak, VO2/HRpeak, COpeak, VEpeak, PETCO2peak, SpO2peak and 6-Minute Walking Distance (6MWD) increased (|t| > 2.167, P < 0.05), while the average Lowest VE/VCO2 and VE/VCO2 slope decreased (t > 2.264, P < 0.05) in the exercise group. Compared with the control group, the FEV1/FVC, AT, WRpeak, VO2peak, VO2/HRpeak, COpeak and 6MWD increased in the exercise group (|t| > 2.168, P < 0.05). Conclusion:The holistic cardiopulmonary function of stable patients with PAH decreases. CPET-based individualized moderate-intensity exercise could enhance the cardiopulmonary functional reserve and exercise capacity of patients with PAH.

ABSTRACT

OBJECTIVE@#Systemic sclerosis (SSc) is a remarkably systemic heterogeneous connective tissue disease with many organs involved. The heart is one of the major organs involved, carrying the threat of sudden cardiac death, especially in diffuse cutaneous SSc. This review summarizes the pathophysiology, types, new diagnostic approaches, and imaging and novel therapies of primary cardiac complications while underlining the effects of recently developed non-contrast cardiovascular magnetic resonance (CMR) in early diagnosis.@*DATA SOURCES@#Medline and Embase were searched for articles published up to July 2019. A combination of Medical Subject Headings (MeSH) terms and keywords pertaining to SSc ("Scleroderma, Systemic" OR "Systemic sclerosis" OR' SSc"), AND cardiology ("cardiology" OR "heart" OR "cardiac") were applied to the search strategies.@*STUDY SELECTION@#Literature was mainly printed in English and Chinese about cardiac complications in systemic sclerosis. After selected simply on the title and abstract, the articles were included for the full text. Article type was not limited.@*RESULTS@#Relevant cardiac manifestations are complex, including arrhythmias, pericardial effusion, myocardial dysfunction, and valvular diseases. Even though the symptoms of cardiac complications are well known, unfortunately, they appear to be poor prognostic factors. As systemic sclerosis with cardiac complications has a high mortality rate and patients might have a poor quality of life, it is essential to promote early diagnosis and treatment. With the advent of non-invasive imaging techniques, such as CMR, early diagnosis of cardiac complications in SSc is becoming more effective.@*CONCLUSIONS@#Cardiac complications play an essential role in SSc and carry the threat of sudden cardiac death. More basic and clinical studies are warranted to develop better management of cardiac involvement in patients with SSc.

ABSTRACT

OBJECTIVE@#To compare the immunomodulatory effects of the 2nd generation of tyrosine kinase inhibitors (TKIs)-dasatinib and nilotinib as well as the 1st generation of TKI-imatinib on chronic myeloid leukemia (CML) patients.@*METHOD@#To evaluate the T cell subtypes by flow cytometry on the CML patients of our center who received the treatment with dasatinib (n=10), nilotinib (n=26) or imatinib (n=44) for more than 3 months, and to analyze and correlate these data with the clinical remission situations and prognosis.@*RESULTS@#80.0% of the patients in dasatinib group, 16.6% of the patients in nilotinib group and 27.5% of the patients in imatinib group respectively had a Th1 proportion in the peripheral blood (Th1/CD4 T) above the upper limit of normal. More specifically, the Th1 proportion in dasatinib group (30.86%±9.75%) was significantly higher than that in nilotinib group(17.37%±9.35%) (P<0.001) and that in imatinib group (20.79%±9.01%) (P<0.001). Among the 3 groups, both the CD8 T cell proportion (CD8 T/Lymphocyte) and the Th2 proportion (Th2/CD4 T) in the peripheral blood did not show a statistically significant difference. The Treg proportion (Treg/CD4 T) in dasatinib group (1.31%±0.10%) was significantly lower than that in nilotinib group (2.65%±0.97%) (P<0.001) and that in imatinib group(2.99%±1.40%) (P<0.001).Among all the CML patients analyzed, for CML patients who had a Th1 proportion above the upper limit of normal(25.8%) (n=28), 84.62% of these patients obtained CCyR (complete cytogenetic response), 71.43% of these patients obtained MMR (major molecular response), 71.43% of these patients obtained MR4.5; for CML patients who had the Th1 proportion in the normal range(11.8%-25.8%) (n=45), 90.7% of these patients obtained CCyR, 75.56% of these patients obtained MMR, and 75.56% of these patients obtained MR4.5; for CML patients who had the Th1 proportion below the lower limit of normal (11.8%) (n=21), 57.14% of these patients obtained CCyR, 47.62% of these patients obtained MMR, and 47.62% of these patients obtained MR4.5. The above-mentioned data shows that the patients in high Th1 group and the normal Th1 group obtained the higher remission rate as well as the deeper remission level.@*CONCLUSION@#This study shows that during the CML treatment with TKIs, the increased or normal Th1 proportion indicates a bigger chance for CCyR, MMR, and MR4.5. Dasatinib may significantly increase the level of Th1 while decrease the level of Treg in the patients, as compared with nilotinib and imatinib.

ABSTRACT

Objective:To explore the effect of home-based rehabilitation on children with congenital muscular torticollis (CMT). Methods:From January, 2016 to January, 2018, 60 children with CMT were randomly divided in to control group (n = 30) and observation group (n = 30). Both groups received comprehensive physical therapy; the observation group received home-based rehabilitation in addition. Three months after treatment, the sternocleidomastoid thickness, severity classification of CMT, and clinic effect were compared. Results:After treatment, the sternocleidomastoid thickness decreased in both groups (t > 9.862, P < 0.001), and was better in the observation group than in the control group (t = 5.468, P < 0.001); the severity classification of CMT decreased in both groups (|Z| > 5.857, P < 0.001), and was better in the observation group than in the control group (Z = -2.226, P < 0.05), as well as the clinical effect (U = 2359, P = 0.018). Conclusion:Home-based rehabilitation combined with comprehensive physical therapy is superior to comprehensive physical therapy only.

ABSTRACT

OBJECTIVE@#To investigate the early clinical effects of transforaminal endoscopic spine system (TESSYS) for the treatment of bilateral lumbar disc herniation in single segment.@*METHODS@#The clinical data of 38 patients with single-segment bilateral lumbar disc herniation treated by TESSYS technique from February 2016 to February 2018 were retrospectively analyzed. There were 26 males and 12 females, aged from 30 to 55 years old with an average of(35.2±6.4) years, 6 cases of L₃,₄, 22 cases of L₄,₅, and 10 cases of L₅S₁1. Using the intervertebral foramen endoscope produced by Joimax GmbH, Germany, under local anesthesia, bilateral puncture to the outside of the intervertebral foramen of the diseased segment, four-stage dilatation catheter to complete the progressive enlargement of the intervertebral foramen, and the ring saw progressively enlarge the intervertebral foramen. The bilateral foramen was placed and the herniated nucleus was removed until the nerve root was completely released. Postoperatively, the patients were reviewed on regular outpatient visits and telephone follow-ups. Visual analogue scale (VAS) and Oswestry Disability Index (ODI) were compared before operation and after operation at 1, 3, 6, 12 months respectively. At the final follow-up, according to modified MacNab criteria to evaluate the clinical effect.@*RESULTS@#Thirty-six patients underwent successful surgery and were followed up for more than 12 months. The ODI score and VAS score of the lower extremities pain at 1, 3, 6, 12 months after operation were obviously improved (0.05). At the final follow-up, according to MacNab criteria, 14 cases got excellent results, 16 good, 4 fair, 2 poor.@*CONCLUSIONS@#Using TESSYS technique to remove the bilateral herniated nucleus from single segment can fully decompress for the nerve root, and can be effectively applied to patients with single-segment bilateral lumbar disc herniation.

ABSTRACT

Depression is a debilitating psychiatric disorder with a huge socioeconomic burden, and its treatment relies on antidepressants including selective serotonin reuptake inhibitors (SSRIs). Recently, the melatonergic system that is closely associated with the serotonergic system has been implicated in the pathophysiology and treatment of depression. However, it remains unknown whether combined treatment with SSRI and melatonin has synergistic antidepressant effects. In this study, we applied a sub-chronic restraint stress paradigm, and evaluated the potential antidepressant effects of combined fluoxetine and melatonin in adult male mice. Sub-chronic restraint stress (6 h/day for 10 days) induced depression-like behavior as shown by deteriorated fur state, increased latency to groom in the splash test, and increased immobility time in the forced-swim test. Repeated administration of either fluoxetine or melatonin at 10 mg/kg during stress exposure failed to prevent depression-like phenotypes. However, combined treatment with fluoxetine and melatonin at the selected dose attenuated stress-induced behavioral abnormalities. Moreover, we found that the antidepressant effects of combined treatment were associated with the normalization of brain-derived neurotrophic factor (BDNF)-tropomyosin receptor kinase B (TrkB) signaling in the hippocampus, but not in the prefrontal cortex. Our findings suggest that combined fluoxetine and melatonin treatment exerts synergistic antidepressant effects possibly by restoring hippocampal BDNF-TrkB signaling.

ABSTRACT

Fluoxetine, an anti-depressant drug, has recently been shown to provide neuroprotection in central nervous system injury, but its roles in subarachnoid hemorrhage (SAH) remain unclear. In this study, we aimed to evaluate whether fluoxetine attenuates early brain injury (EBI) after SAH. We demonstrated that intraperitoneal injection of fluoxetine (10 mg/kg per day) significantly attenuated brain edema and blood-brain barrier (BBB) disruption, microglial activation, and neuronal apoptosis in EBI after experimental SAH, as evidenced by the reduction of brain water content and Evans blue dye extravasation, prevention of disruption of the tight junction proteins zonula occludens-1, claudin-5, and occludin, a decrease of cells staining positive for Iba-1, ED-1, and TUNEL and a decline in IL-1β, IL-6, TNF-α, MDA, 3-nitrotyrosine, and 8-OHDG levels. Moreover, fluoxetine significantly improved the neurological deficits of EBI and long-term sensorimotor behavioral deficits following SAH in a rat model. These results indicated that fluoxetine has a neuroprotective effect after experimental SAH.

ABSTRACT

AIM:To investigate the mutation of FLT3-ITD gene in the patients with newly diagnosed acute myeloid leukemia (AML). METHODS:From March 1, 2015 to June 1, 2017, 207 patients with AML admitted to de-partment of hematology, sichuan provincial people′s hospital were enrolled in this study. The bone marrow samples were collected from the patients. PCR was used to detect the mutation of FLT3-ITD gene. After the corresponding chromosome was obtained by R-banding, the cells were made into strips and banding. Twenty karyotypes with relatively cleavage were automatically selected from each specimen to complete karyotyping. By analysis of the clinical data and following-up the prognosis, the FLT3-ITD gene mutation in diagnostic and evaluative values for AML were performed. RESULTS:FLT3-ITD gene mutation was found in 42 cases of 207 AML patients, the positive rate was 20. 29 % . FLT3-ITD positive patients showed 3 bands. FLT3-ITD gene mutation in 42 patients with positive results showed that FLT3-ITD gene mutations in turn met the end to end, and insert a number of nucleotides, but all the mutations were in-frame mutations. According to the FAB and WHO standard, in 42 cases of FLT3-ITD positive positive patients, M0 accounted for 0.00% , M1 accounted for 2.38% (1/42), M2 accounted for 23.81% (10/42), M3 accounted for 0.00% , M4 accounted for 2.38% (1/42), M5 accounted for 69.05% (29/42), M6 accounted for 0.00% , M7 accounted for 2.38% (1/42). The white blood cell ( WBC) level and complete response (CR) rate in FLT3-ITD positive patients were lower than those in FLT3-ITD negative patients (P<0.05). CONCLUSION:The WBC level and CR rate, which are lower in FLT3-ITD positive patients than those in negative patients, are the clinical risk factors. It will be helpful to determine the prognosis evaluation for AML pa-tients.

ABSTRACT

BACKGROUND:Currently, there is no explicit evidence-based medicine evidence to prove the merits or demerits of absorbable materials in the treatment of fractures of the lateral humeral condyle in children. OBJECTIVE:To evaluate the clinical efficacies of open reduction with absorbable material versus open reduction with Kirschner wire fixation for lateral condylar fracture of the humerus in children.METHODS:WanFang, VIP, CNKI, CBMdisc, EMbase, PubMed were retrieved for controlled trials concerning open reduction with absorbable material versus open reduction with Kirschner wire fixation for treating lateral condylar fracture of the humerus in children. After data extraction and quality evaluations, RevMan 5.3 software was used for systematic review. Postoperative functional recovery of the elbow joint, average hospitalization expenses, adverse events, delayed union, postoperative infection, nerve injury and deformity of the elbow were compared in patients undergoing different treatments. RESULTS AND CONCLUSION:A total of seven articles, involving 449 children with lateral condylar fracture of the humerus, were included for this Meta-analysis. Children in test group received open reduction with absorbable material, while those in control group were subjected to open reduction with Kirschner wire fixation. For treating lateral condylar fracture of the humerus in children, no significant inter-group difference existed in the aspects of postoperative functional recovery of the elbow joint [odds ratio (OR)=0.72, 95% confidence interval (CI) (0.37, 1.41),P=0.34]; postoperative delayed union [OR=0.46, 95%CI(0.16, 1.30),P=0.14]; deformity of the elbow [OR=0.70, 95%CI (0.24, 2.10),P=0.53]. Less adverse events and postoperative infections were observed in the test group compared with the control group [OR=0.17, 95%CI (0.08, 0.38),P < 0.0001;OR=0.09, 95%CI (0.02, 0.38),P=0.001]. However, up to now, we knew of no comparable data concerning average hospitalization expenses and indicators for nerve injury between the two groups. To conclude, compared with Kirschner wire fixation, open reduction with absorbable material can achieve similar effects on lateral condylar fractures of the humerus, but has better effects to prevent adverse events and postoperative infection. Further investigation on large-scale, double-blind, high-quality randomized controlled trials is warranted for confirming our results.

ABSTRACT

BACKGROUND: Bone marrow mesenchymal stem cells (BMSCs) and bone marrow mononuclear cells(BMMNCs) have been both used to treat spastic cerebral palsy. However, the differences in their therapeutic effects remain unknown. OBJECTIVE: To compare the therapeutic effects of BMMSCs and BMMNCs in cerebral palsy children as well as on fine motor function. METHODS: 105 children with spastic cerebral palsy were enrolled and randomly assigned to three groups: BMMSCs group, BMMNCs group and control group. Patients in the two transplantation groups received four intrathecal cell injections, and those in the control group received Bobath therapy, twice a day, for consecutive 3 weeks. The Gross Motor Function Measure (GMFM) and Fine Motor Function Measure (FMFM) were used to evaluate the therapeutic efficacy at 3, 6 and 12 months after transplantation. RESULTS AND CONCLUSION: At 3 months after cell transplantation, scores in A dimension of GMFM and in A, C dimensions of FMFM in BMMSC group were all superior to those of BMMNC group and control group (P < 0.05). At 6 months after cell transplantation, scores in A, B dimensions of GMFM and in A, B, C, D and E dimensions of FMFM in BMMSC group were better than those of BMMNC group and control group (P< 0.05), and total scores of GMFM and FMFM were also better in the BMMSC group (P < 0.05). At 12 months after cell transplantation, scores in A, B and C dimensions of GMFM and A, B, C, D and E dimensions of FMFM scores in BMMSC group were all superior to those of BMMNC group and control group (P < 0.05) as well as the total GMFM and FMFM scores. There were six cases of low intracranial pressure headache in BMMNC group and six cases of low-grade fever in BMMSC group. In summary, both BMMSCs transplantation and BMMNCs transplantation are safe, effective and feasible for the treatment of spastic cerebral palsy in children, and moreover, BMMSCs transplantation is a better method than BMMNCs transplantation to improve gross and fine motor functions of spastic cerebral palsy children.

ABSTRACT

Objective·To investigate changes of immune thrombocytopenia (ITP) patients-derived bone marrow mesenchymal cells (BMCs) in cells survival, cytokines expression as well as the effects of BMCs on the biological behaviors of megakaryocytes. Methods?·?BMCs were collected from 7 ITP patients and 5 normal controls (NC), and cultivated by the whole marrow adherent method. Surface markers and basal apoptosis rate of BMCs were analyzed by flow cytometry (FCM). Proliferation of BMCs was assessed by CCK-8 method. Phorbol 12-myristate 13-acetate (PMA) was used to stimulate differentiation of HEL cells. The induced HEL cells (inHEL) were divided into 3 groups: inHEL cultured alone (group a), inHEL co-cultured with BMCs derived from ITP patients (group b), inHEL co-cultured with BMCs derived from NC (group c). After 72 h incubation, the expression of cell surface proteins (CD41a, CD42b) and cell apoptosis rate were analyzed by FCM. The mRNA and proteins expression levels of cytokines IL6, IL11, TPO, SCF were detected by real-time fluorescent quantitative PCR (RT-qPCR) and enzyme linked immunosorbent assay (ELISA), respectively. Results?·?Compared with NC, BMCs from ITP patients grew progressively slowly (Day 4, P=0.039; Day 6, 10, P=0.009; Day 8, P=0.007), cell basal apoptosis rates were increased [AV+PI- (early apoptosis rate), P=0.036; AV+PI+(late apoptosis rate), P=0.003; AV+PI-/+(total apoptosis rate), P=0.004]. Compared with group a, the expression of CD41a in group c was much higher (P=0.000). The expression of CD41a in group b was higher than that in group a (P=0.015), but still much less than that in group c (P=0.000). Compared with group a, the early and total apoptosis rate in group b, c and the late apoptosis rate in group c were decreased obviously (all P=0.000), whereas there was no obvious change of the late apoptosis rate in group b. However, compared with group c, the late and total apoptosis rate in group b were significantly increased (both P=0.000). The expression levels of IL6, SCF mRNA and IL6 protein were significantly decreased in ITP BMCs (all P=0.000), but there was no obvious difference in the expression levels of IL11 and TPO between ITP BMCs and NC BMCs. Conclusion?·?BMCs from ITP patients show some defects in supporting megakaryocytic differentiation and survival under co-culture conditions, which mechanisms are related to the reduction of IL6 and SCF expression.

ABSTRACT

·AIM: To explore whether the drainage angle could be reopened by surgery in patients with severe acute angle-closure glaucoma at " the greatest degree " of angle closure, and to study the treatment methods, such as double-paracentesis, phacoemulsification combined with goniosychialysis, and the effectiveness. ·METHODS: Retrospective observational case series. From November 2008, to November 2015, there were 33 patients with severe acute angle-closure glaucoma and 360° angle closure. Drug treatment showed no effect on them, so initial double-paracentesis ( anterior chamber paracentesis combined with vitreous paracentesis ) was applied. Then, either phacoemulsification combined with goniosychialysis or trabeculectomy surgery was performed after 7-14d, which was chosen based on the result of gonioscope during the surgery. The intraocular pressure, angle changes, and complications were observed. The follow-up period was 6mo to 3a. ·RESULTS: Of 33 participants enrolled, 32 had normal intraocular pressure after " double-paracentesis" ( 2 had normal intraocular pressure after laser peripheral iridotomy ). The mean intraocular pressure was significantly reduced from 53. 4 ± 10. 7mmHg to 16. 9 ± 13. 2mmHg ( t= 9. 21, P<0. 001 ) by applying " double-paracentesis", and 1 still had higher intraocular pressure. The mean intraocular pressure ( 16. 7 ± 4. 8mmHg ) was 0. 2mmHg lower after phacoemulsification than after" double- paracentesis " while there was no significant difference (t=0. 38,P>0. 05). One patient had abnormal intraocular pressure until 30d after phacoemulsification. Every participant had 360° angle closed before " double-paracentesis", 32 patients had opened angle ( mean 131. 8°± 111. 3°) after " double-paracentesis " and mean (228. 6°± 108. 3°) during phacoemulsification, and mean (234. 6°± 107. 2°) at 3mo after phacoemulsification. There was a significant difference between the post -paracentesis and intraoperative values ( t = 4. 52, P <0. 001 ). There was no difference between the intraoperative and postoperative values ( t = 0. 46, P>0. 05). No patients had serious adverse events. · CONCLUSION: For the " maximum degree " angle closure of severe acute angle-closure glaucoma, "double-paracentesis" combined with phacoemulsification can be chosen to open the angle gradually, and reduce intraocular pressure in vast majority of patients.

ABSTRACT

<p><b>OBJECTIVE</b>To compared the early outcomes of patients undergoing elective surgeries for colon cancer with and without preoperative mechanical bowel preparation.</p><p><b>METHODS</b>Between July, 2014 and February, 2016, patients undergoing elective surgery for colon cancer with primary anastomosis were randomly assigned into control group with mechanical bowel preparation 12 h before surgery and treatment group without mechanical bowel preparation. Baseline data collection was completed within 12 h after the operation. The levels of hemoglobin, total protein, albumin, prealbumin and albumin<globulin ratio of the patients were recorded at 1 day before surgery and 1 day and 5 days after the surgery. The patients were followed up till 30 days after the surgeries and the complications were recorded.</p><p><b>RESULTS</b>Seventy-six patients were assigned in the treatment group and 72 in the control group. Significant differences were found in the incidence of wound infection and intra-abdominal infection (P<0.05) but not in that of anastomotic leakage or early postoperative bowel obstruction (P>0.05) between the two 2 groups. The first flatus time (P=0.03) and prealbumin level on the first postoperative day (P=0.03) differed significantly between the two groups, but the operation time was similar between them (P=0.06).</p><p><b>CONCLUSION</b>In patients undergoing elective surgeries for colon cancer, preoperative mechanical bowel preparation is associated with increased postoperative complications, delayed recovery of intestinal motility and poorer nutrition status early after the operation.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the antitumor effect of arsenic trioxide (ATO) combined with itraconazole (ITRA) on human multiple myeloma NCI-H929 cells by synergistically inhibiting Hedgehog (HH) signaling pathway.</p><p><b>METHODS</b>The inhibitory rate of NCI-H929 cells was assayed by MTT method. Tumor weight, tumor weight inhibition rate, and tumor volume of mouse model with multiple myeloma were examined. The ELISA were appled to detect the M-protein, qPCR and Western blot were used respectively to detect the expression level of Ptch, SMO, Gli and downstream target genes, the survival rate of tumor-bearing mice was analyzed.</p><p><b>RESULTS</b>ATO combined with ITRA significantly inhibited NCI-H929 cell proliferation as compared with a single administration. The combination of ATO and ITRA could synergistically inhibit tumor growth and obviously reduced tumor burden, survival time of tumor-bearing mice was significantly prolonged. qPCR and Western blot results confirmed that the ATO combined with ITRA could significantly down-regulated expression of Gli1, leading to significantly decrease of cyclinD1 and BCL-2 expression levels.</p><p><b>CONCLUSION</b>ATO combined with ITRA can more strongly suppress the growth of multiple myeloma NCI-H929 cells, as compared with a single administration. The synergistic effect of ATO and ITRA significantly down-regulates expression of Gli1 in HH signaling pathway, moreover the inhibition of target gene overexpression may be one of two drug mechanisms.</p>
