Objective It remains a controversy whether 5-lipoxygenase (5-LOX) is associated with colon cancer stem cells.This study was to investigate the effect of the 5-LOX inhibitor MK886 in maintaining the stemness of the human colon cancer cell line HT-29.Methods Using CCK-8 assay, we examined the inhibitory effects of different concentrations of MK886 (12.5, 25, 50, 75, 100, and 200 μmol/L) on the colon cancer HT-29 cells cultured in vitro and calculated its half-inhibitory concentration (IC50).Then, we detected the effects of MK886 IC50 on the clone-and sphere-forming abilities of the cells, determined the mRNA expressions of the stemness markers CD133, Lgr5, Oct4 and Ascl2 by real-time PCR after 24 and 48 hours of MK886 IC50 intervention, and measured their protein expressions by Western blotting after 24, 48 and 72 hours of MK886 IC50 intervention.Results The inhibition rates of MK886 on the HT-29 cells at 24 and 48 hours were significantly increased in a time-and dose-dependent manner ([14.99±3.06] and [19.98±0.57]％ at 12.5 μmol/L, [20.46±1.14] and [34.97±6.02]％ at 25 μmol/L, [50.76±5.94] and [66.90±5.74]％ at 50 μmol/L, [66.84±1.77] and [73.11±2.48]％ at 75 μmol/L, [72.67±2.36] and [77.78±3.30]％ at 100 μmol/L, [83.67±0.24] and [84.69±2.24] ％ at 200 μmol/L) as compared with the blank control (0％ and 0％) (P<0.05).The clone-forming rate and number of spheres formed were remarkably lower in the MK886 intervention than in the control group ([10.60±1.71] vs [44.67±3.21]％, P<0.05;6.00±1.60 vs 19.07±2.89, P<0.05).After 24 and 48 hours of MK886 intervention, the mRNA expression of CD133 in the HT-29 cells was markedly up-regulated in comparison with that at 0 hour (0.72±0.10 and 0.39±0.07 vs 1.66±0.33, P<0.05), and so were those of Lgr5, Oct4 and Ascl2 (P<0.05).Conclusion The 5-LOX inhibitor MK886 can inhibit the proliferation and clone-and sphere-forming abilities of human colon cancer HT-29 cells by down-regulating the expressions of the stemness markers and thus suppressing the stemness of the colon cancer stem cells.

OBJECTIVE: To observe the effects of Shenqi bufei decoction on air passage and lung function of COPD model rats with lung-qi deficiency.METHODS: Quantitative stimulation with tobacco and SO2 and papain aerosol inhalation were used to establish model COPD rats with lung-qI deficiency.Sixty male rats were randomly divided into: normal group (N),model group(M),low dose treatment group(LT),medium dose treatment group (MT),high dose treatment group (HT),and glucocorticoid treatment group (GCT).Pathomorphological change of lung tissue in rats was observed with light microscope.The thickness of airway wall and smooth muscle layer of the small airway and lung function were measured by means of semi-quantitative image analysis system with lung function detection and analysis system respectively.RESULTS: As compared to N group,in M group the thicknesses of the small airway wall and smooth muscle layer were significantly increased(P

Objective To evaluate the effect of rehabilitation training on dysphagia and trismus in patients with nasopharyngeal carcinoma after radiotherapy.Methods Fony-three post-radiotherapy nasopharyngeal carcino-ma patients were divided into a rehabilitation group and a control group.Both groups were subjected to routine treat-ment,while the rehabilitation group received rehabilitation training in addition.The patients were assessed with a wa-ter-swallowing test of swallowing.Late effects of normal tissues/subjective and objective medical analysis(LENT/SOMA)scored and inter-incisor distance were measured to assess trismus before and after treatment.Results The rehabilitation group displayed significant improvement in swallowing as well as increased inter-incisor distance.Con-clusions Rehabilitation training can improve swallowing,prevent or delay trismus and improve the quality of life of patients.

Objective To evaluate the clinical efficacy and safety of endovascular treatment for intracranial venous sinus thrombosis based on individual condition. Methods Twelve patients with intracranial venous sinus thrombosis were treated with endovascular management according to the severity and course of disease after they failed to respond to anticoagulant therapy. The clinical signs and symptoms,cerebrospinal fluid pressure and arteriovenous circulation time were observed and followed up (including MRV). Intravenous thrombolysis and mechanical thrombus maceration were carried out in all 12 patients,while intravenous thrombolysis, mechanical thrombus maceration in combination with intra-arterial thrombolysis were employed in 3. After the treatment, anticoagulant therapy was carried out for 6 months.The patients were followed up for 12 to 24 months. Results Of the twelve patients, clinical signs and symptoms included slight headache (2 cases), mild hemiplegia (1 case), ambiopia or blurred vision (3 cases). The cerebrospinal fluid pressure returned to under 26 cm H2O (1 cm H2O =0.098 kPa)following treatment from 28 to 38 cm H2O [ mean (32. 4 ±3.0) cm H2O] in preoperative measurement and the arteriovenous circulation time returned to below 10 s in all patients following treatment. Neither recurrence of thrombosis nor new symptoms of neurologic dysfunction was observed. No procedure-related intracranial or systemic hemorrhagic complications occurred both during and after the operation with the exception of a subcutaneous bleeding at the venopuncture site. Conclusion Endovascular treatment is effective and safe for patients with intracranial venous sinus thrombosis.

Objective: To analyze the epidemiological characteristics of pulmonary tuberculosis cases at ages of 60 years and older in Quzhou City, Zhejiang Province, so as to provide the evidence for formulating the pulmonary tuberculosis control strategy among the elderly. Methods: The data pertaining to pulmonary tuberculosis cases at ages of 60 years and older in Quzhou City from 2010 to 2020 were collected through the Tuberculosis Management Information System of the China Disease Prevention and Control Information System. The trends for incidence, population distribution, diagnosis and treatment of pulmonary tuberculosis cases aged 60 years and older were analyzed using a descriptive epidemiological method. Results: Totally 8 754 pulmonary tuberculosis cases aged 60 years and older were reported in Quzhou City from 2010 to 2020, accounting for 47.65% of all pulmonary tuberculosis cases, and the number of pulmonary tuberculosis appeared a tendency towards a rise ( χ2trend=173.320, P<0.001 ), while the incidence of pulmonary tuberculosis showed a tendency towards a decline ( χ2trend=389.820, P<0.001 ), with an annual decline rate of 177.11/105. There were 4 307 smear-positive pulmonary tuberculosis cases, accounting for 58.71% of all smear-positive cases, and the number of smear-positive pulmonary tuberculosis cases showed a tendency towards a rise ( χ2trend=126.320, P<0.001 ), while the proportion of smear-positive cases showed a tendency towards a decline ( χ2trend=21.680, P<0.001 ), with an annual smear-positive rate of 87.14/105. The incidence of pulmonary tuberculosis was 256.94/105 among males and 91.43/105 among females at ages of 60 years and older ( χ2=20.903, P<0.001 ). The highest incidence of pulmonary tuberculosis was seen in patients aged 80 to 84 years ( 235.17/105 ), and farmers were the predominant occupation ( 7 171 cases, 81.92% ), while the highest number of cases was reported in Quzhou City (8 676 cases, 99.11%). There were 7 752 treatment-naïve cases ( 88.55% ), while 5 830 cases with delay in seeking healthcare services, and the proportion of delay in seeking healthcare services showed a tendency towards a rise from 2010 to 2020 ( χ2trend=4.853, P=0.028 ), with an annual mean delay rate of was 66.60%. Conclusion The incidence of pulmonary tuberculosis appeared a tendency towards a decline among patients aged 60 years and older in Quzhou City from 2010 to 2020, and the elderly aged 80 years and older and farmers should be paid more attention.

To explore the effect of releasing aqueous humor of anterior chamber through lateral incision of cornea in treating early elevated intraocular pressure ( lOP ) after implantation of implantable collamer lens ( lCL) .METHODS: Patients with elevated lOP were analyzed after lCL implantation. When the lOP>25mmHg, aqueous humor was released slowly through lateral incision of cornea, and made the lOP reduce to 10 ~13mmHg. After operation, lOP was measured every 2h. The releasing of aqueous humor was repeated until the lOP was decreased to normal.RESULTS: One hundred sixty - seven patients ( 330 eyes) were implanted lCL, while the lOP of 32 patients (62 eyes) was higher than 25mmHg after lCL implantation. Viscoelastic material was found in aqueous humor of most of high lOP patients, and the lOP of 48 eyes did not increase again through releasing aqueous humor once. The lOP of all these eyes was decreased to normal through releasing aqueous humor in 3 times at most. There were no abnormal in postoperative follow-up.CONCLUSlON:The main reason of early elevated lOP after lCL implantation is the remaining of viscoelastic material of eyes. Releasing aqueous humor through lateral incision of cornea can decrease lOP effectively. lt is a simple, safe, painless and repetition, which the patients are willing to accept.

Objective To evaluate the clinical value of 131 Ⅰ SPECT/CT in the differentiation of indeterminate 131Ⅰ uptake on planer whole body scan (WBS) for patients with DTC after 131Ⅰ treatment. Methods Fifty-six DTC patients ( male: 19, female: 37, mean age: 45 ± 15 years, ranging from 20 to 85 years) underwent 131Ⅰ treatment. 131Ⅰ WBS was performed five days after 131 Ⅰ treatment, followed by regional 131Ⅰ SPECT/CT for the indeterminate foci with abnormal uptake on 131Ⅰ WBS. The diagnostic difference of the two imaging modalities was compared by x2 test. Results There were 288 foci with abnormal uptake on 131 Ⅰ WBS, including 108 indeterminate foci (37.5%). Subsequent 131Ⅰ SPECT/CT identified 27 foci as DTC metastases (25.0%) and 71 foci as non-metastases such as benign lesions at nose, oral cavity, salivary gland, maxillary cyst, thyroid remnant, thymus, gallbladder, gastrointestinal tract, and uterus, or non-specific uptake of body contaminations (65.7%). However, the remaining 10 foci (9.3%) remained indeterminate on 131 Ⅰ SPECT/CT imaging. The diagnostic accuracy of 131 Ⅰ SPECT/CT was significantly higher than that of 131Ⅰ WBS (x2 = 102.35, P＜0. 01). Conclusion 131Ⅰ SPECT/CT could significantly improve the diagnostic accuracy for the differentiation of indeterminate foci with abnormal uptake on 131Ⅰ WBS.
