ABSTRACT

Objective:To investigate the advantages and safety of subxiphoid uniportal thoracoscopic thymectomy.Methods:From October 2014 to December 2019, a total of 308 patients diagnosed with early stage thymic epithelial tumor underwent uniportal thoracoscopic thymectomy were included. Subxiphoid group including 40 males and 37 females, aged 32-80 years old, mean age(58.0±11.8)years old. Intercostal group including 114 males and 117 females, aged 25-78 years old, mean age(54.8±11.4)years old. Short-term and long-term postoperative pain scores was compared in a propensity score matching analysis.Results:Propensity score analysis revealed that 62 patients treated with the subxiphoid approach and 62 patients treated with the lateral intercostal approach had the same baseline characteristics. There were no significant differences in lesion size, stage, pathological type, intraoperative blood loss, postoperative drainage volume and postoperative hospital stay between the two groups( P>0.05). Compared with those in the intercostal group, patients in the subxiphoid group yielded lower pain scores on the first day after operation and less patients with postoperative pain lasting more than 3 months. Patients required for additional analgesic therapy in subxiphoid group was less than intercostal group. One patient in subxiphoid group developed myasthenia after operation, which prolonged the duration of mechanical ventilation. No serious perioperative complications and death occurred in other patients. Conclusion:Subxiphoid uniportal thoracoscopic thymectomy is safe and feasible, it has the advantages of no injury to intercostal nerve and less short-term and long-term postoperative pain compared with intercostal approach.

ABSTRACT

Compared to conventional cancer treatment, combination therapy based on well-designed nanoscale platforms may offer an opportunity to eliminate tumors and reduce recurrence and metastasis. In this study, we prepared multifunctional microspheres loading I-labeled hollow copper sulfide nanoparticles and paclitaxel (I-HCuSNPs-MS-PTX) for imaging and therapeutics of W256/B breast tumors in rats. F-fluordeoxyglucose (F-FDG) positron emission tomography/computed tomography (PET/CT) imaging detected that the expansion of the tumor volume was delayed (<0.05) following intra-tumoral (i.t.) injection with I-HCuSNPs-MS-PTX plus near-infrared (NIR) irradiation. The immunohistochemical analysis further confirmed the anti-tumor effect. The single photon emission computed tomography (SPECT)/photoacoustic imaging mediated by I-HCuSNPs-MS-PTX demonstrated that microspheres were mainly distributed in the tumors with a relatively low distribution in other organs. Our results revealed that I-HCuSNPs-MS-PTX offered combined photothermal, chemo- and radio-therapies, eliminating tumors at a relatively low dose, as well as allowing SPECT/CT and photoacoustic imaging monitoring of distribution of the injected agents non-invasively. The copper sulfide-loaded microspheres, I-HCuSNPs-MS-PTX, can serve as a versatile theranostic agent in an orthotopic breast cancer model.

ABSTRACT

Objective To compare the clinical significance of peripheral blood neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) in predicting prognosis of patients with hepatocellular carcinoma (HCC).Methods The clinical data of 661 patients with HCC were retrospectively analyzed.Routine peripheral blood test results were used to calculate the NLR and PLR,and the receiver operating characteristic (ROC) curves were drawn.Using the thresholds of NLR and PLR,the patients were divided into the low NLR group and the high NLR group,and the low PLR group and the high PLR group.Overall survival (OS) and disease free survival (DFS) were evaluated by the Kaplan-Meier method.Independent prognostic predictors were determined by the Cox proportional hazard model.Results The NLR and PLR thresholds were 2.790 and 99,respectively.Analysis of the ROC curves showed higher NLR and PLR were significantly associated with poorer OS and DFS (all P < 0.05).Multivariate analysis showed that NLR was an independent risk factor of OS and DFS (both P < 0.05).The results remained unchanged when the NLR was further analyzed by applying different cut-off values of 2.810 and 3.In subgroup analysis,NLR remained an independent factor of Barcelona Clinical Liver Cancer staging system (BCLC) 0/A/B (P < 0.05 for all measurements).Conclusion An elevated preoperative NLR could be a better prognostic predictor for HCC patients in comparison with PLR,especially for BCLC 0/A/B patients.

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the correlation between skeletal muscle mass and age among check-up adults.</p><p><b>METHODS</b>The study objects were those who aged 18-87 years old and came to a city hospital of Qiqihar for health examination from December, 2013 to September, 2014, excepted those with coronary heart disease, infectious disease, endocrine system disease, hypertension, anemia, cancer, liver disease, kidney disease and those carrying with heart pacemaker. A total of 1 836 respondents were finally enrolled into analysis. Appendicular Skeletal Muscle (ASM) was measured by a Body Composition Analyzer, and relative skeletal muscle index (RSMI) was calculated. The relationship among ASM, RSMI and age was assessed by linear regression analysis. The difference of height, weight, BMI, waist-hip-ratio (WHR), total muscle mass and percentage of body fat between genders were tested by t-test. The difference of ASM and total skeletal muscle mass between genders and among age groups was tested by multi-factor variance analysis. The difference of the muscle decline between genders was compared by Chi-square test.</p><p><b>RESULTS</b>The total muscle mass in males was (52.22 ± 6.65) kg, which was significantly higher than that in females ((38.05 ± 4.39) kg) (t=28.20, P<0.001). ASM in 18-29, 30-39, 40-49, 50-59, 60-69, 70-87 years was (24.64 ± 3.23), (24.00 ± 3.12), (24.35 ± 3.03), (23.33 ± 2.97), (22.54 ± 2.91) and (21.40 ± 3.36) kg (F=16.12, P<0.001) in males, respectively, and (16.48 ± 3.14), (16.72 ± 1.93), (16.75 ± 1.93), (16.84 ± 2.28), (16.52 ± 2.35) and(14.70 ± 2.37)kg (F=4.38, P=0.001) in females, respectively. ASM in males ((23.72 ± 3.16) kg) was higher than that in females ((16.65 ± 2.25) kg) (t=55.97, P<0.001).

ABSTRACT

Background Researches showed that ADP-ribosylation factor (ARF) promotes intracorneal secretion of multiple angiogenesis-related factors,such as vascular endothelial growth factor (VEGF) and nitricoxide synthase (NOS) etc., and therefore results in corneal neovascularization.However, whether ARF affects the tube formation of human retinal endothelial cells(HRECs) is unelucidated.Understanding the effect of ARF tube formation of HRECs is important for the target treatment of retinal vascular diseases.Objective The aim of this study was to explore the effect and mechanism of ARF inhibitor on tube formation of HRECs in vitro.Methods HRECs (HREC line) were cultured and passaged.The growth-well cells were harvested and divided into two groups.The cells were regularly cultured in the control group,and ARF antagonist (lml) was added in the culture medium in the ARF antagonist group.The expression levels of ARFmRNA and protein in the cells were examined by reverse transcription (RT)-PCR and Western blot.The morphology and number of HREC tube formation were detected by using three-dimensional Matrigel assay.The relative expression levels of VEGF, NOS, focal adhesion kinase (FAK) and heat shock protein 90 (HSP90) at gene level and protein level were examined by RT-PCR and Western blot in vitro.Results The relative expression levels of ARFmRNA in the cells were 0.65 ±0.14 and 0.32±0.10, and those of ARF protein were 0.85±0.15 and 0.24±0.17 in the control group and ARF antagonist group,showing significant differnces between the two groups (t =7.32, P =0.00;t =5.15, P =0.00).The number of HREC tube formation was (34.66±8.57)/field in the ARF antagonist group, which was significantly lower than (51.46±7.12)/field in the control group (t=2.99 ,P=0.04).The relative expression levels of VEGF mRNA, NOSmRNA and their proteins in the cells were significantly lower than those of the control group (t =3.02, P =0.04;t =3.68, P =0.02;t =3.33,P=0.03;t=2.89 ,P=0.04).The relative expression levels of FAKmRNA and HSP90mRNA in the ARF antagonist group were 0.65±0.18 and 0.28±0.05 ,which were significantly lower than 0.76±0.25 and 0.46±0.09 in the control group (all at P<0.05).Conclusions ARF antagonist appears to have an inhibitory effect on the tube formation ability of HRECs propably by down-regulating the expressions of VEGF, NOS and the downstream signal transduction factors FAK and HSP90 in HRECs in vitro.

ABSTRACT

Objective To investigate the effects of different acupuncture therapies on serum branched-chain amino acids (BAC and free tryptophan (F-Trp) in high-intensity military training soldiers. Methods Ninety healthy soldiers were randomly allocated to groups A, B and C, 30 soldiers each. Group A received treatment with electroacupuncture at Zusanli; group B, treatment by cupping on Zusanli;group C, no treatment. The three groups did a high-intensity 5 km running exercise after two weeks of treatment. Serum BACC and F-Trp contents were measured in the three groups before and at the end of treatment and at five days after treatment. Results It can be seen from table 2 that there were no statistically significant pre-treatment differences in serum BACC and F-Trp contents between the three groups of soldier subjects (P>0.05); there were statistically significant pre-/post-treatment differences in serum BACC and F-Trp contents in the three groups of soldier subjects (P<0.05). There was a statistically significant post-treatment difference in serum BACC content between group A or B and group C (P<0.05). There was a statistically significant difference in serum F-Trp content between group A or B and group C at the end of treatment and at five days after treatment (P<0.05). Conclusion Acupuncture therapy can effectively improve bodily anti-fatigue ability and reduce high-intensity exercise induced muscular injury in military training soldiers.

ABSTRACT

BACKGROUND:Research on hand braces is relatively backward, which is difficult to be promoted widely. Zone II extensor tendon has a complex structure, and poor recovery is commonly seen after injury. The main treatment for zone II extensor tendon injury is the fixation with plaster slab, plywood and polymer materials, and up to now, there is no ideal brace for zone II extensor tendon injury. OBJECTIVE:To evaluate the effect of home-made multi-function hand brace on the repair of zone II extensor tendon injury. METHODS:Seventy-six patients with zone II extensor tendon injury were randomly divided into test group and control group, with 38 in each group. In the test group, patients were given appropriate rehabilitation education and multi-function hand brace based apart from conventional hand surgery on zone II extensor tendon; in the control group, patients underwent conventional hand surgery and guiding functional training. Total active motion of the extensor tendons of fingers were evaluated at 1, 2, 3 months after treatment; and the manual dexterity and fine motor of the hand were assessed at 2 and 3 months after treatment. RESULTS AND CONCLUSION:The difference in the total active motion of extensor tendons of fingers was of great significance between the two groups at 1, 2, 3 months after treatment (P 0.05), but less cost was used for one point increase in the above-mentioned three functional scores of the test group than the control group (P < 0.05), indicating the implementation of cost-effective treatment. This home-made brace can prevent adhesions and anchylosis during the postoperative auxiliary exercise; meanwhile, it can improve the range of motion, flexibility and fine motor ability of the hand and has a higher cost performance in the postoperative adjuvant exercise therapy of zone II extensor tendon injury.

ABSTRACT

Objective To investigate the effects of electroacupuncture on head Shen-acupoints on cognitive dysfunction after stroke. Methods 35 cases with cognitive dysfunction after stroke were divided into treatment group (n=19) and control group (n=16). The control group received conventional treatment, while the treatment group received electroacupuncture on Sishencong (EX-HN1), Shenting (GV24) and Benshen (GB13) in addition. They were assessed with Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) before and after 4-week treatment. Results The scores of MMSE and MoCA increased more in the treatment group than in the con-trol group (P<0.05). The scores of visuospatial abilities and executive functions, attention and concentration, calculation, memory and orien-tation of MoCA improved more in the treatment group than in the control group (P<0.05). Conclusion Electroacupuncture on head Shen-acupoints can improve cognitive function in patients after stroke.
