AIM: To compare the control effectiveness among orthokeratology(OK), defocus incorporated multiple segments(DIMS)and single-vision spectacles(SVS)in adolescent myopia.METHODS: Retrospective study. A total of 111 myopic patients(221 eyes)in Ningbo Aier Guangming Eye Hospital from April 2020 to March 2021 were selected, and they were grouped into OK group(42 cases, 83 eyes), DIMS group(30 cases, 60 eyes)and SVS group(39 cases, 78 eyes)according to the method in myopia correction. All patients were followed up for 24mo, and the changes of axial length and spherical equivalent before and after treatment were recorded and analyzed.RESULTS: After 6, 12, 18 and 24mo of treatment, the axial length grew in three groups of patients, and the growth of axial length in SVS group was higher than that in OK group and DIMS group(P<0.01). After 24mo of treatment, the control effect of axial length with OK and DIMS was 59.7% and 41.7% respectively. After 12, 18 and 24mo of treatment, the spherical equivalent increased in both DIMS and SVS groups, and the increase of spherical equivalent in SVS group was higher than that in DIMS group(P<0.01). After 24mo of treatment, the control effect of myopia with DIMS was 58.6%.CONCLUSION: Both OK and DIMS showed good clinical effectiveness in the control of adolescent myopia, and the effectiveness of OK is better than that of DIMS.

Guanxin Danshen Dripping Pills Improve Quality of Life and Cardiovascular Prognoses of CHD Patients after PCI with Anxiety or Depression (GLAD Study): A Randomized Double-Blind Placebo-Controlled Study / 中国结合医学杂志

OBJECTIVE@#To assess the efficacy and safety of Guanxin Danshen Dripping Pills (GXDS) in the treatment of depression or anxiety in patients with coronary heart disease (CHD) after percutaneous coronary intervention (PCI).@*METHODS@#From September 2017 to June 2019, 200 CHD patients after PCI with depression and anxiety were included and randomly divided into GXDS (100 cases) and placebo control groups (100 cases) by block randomization and a random number table. Patients in the GXDS and control groups were given GXDS and placebo, respectively, 0.4 g each time, 3 times daily for 12 weeks. The primary outcomes were scores of Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Scale (GAD-7) and the Seattle Angina Pectoris Scale (SAQ). The secondary outcomes included 12 Health Survey Summary Form (SF-12) scores and the first onset time and incidence of major adverse cardiovascular events (MACEs). Other indices including blood pressure, blood lipids, microcirculation and inflammatory-related indices, etc. were monitored at baseline, week 4, and week 12.@*RESULTS@#In the full analysis set (200 cases), after treatment, the PHQ-9 and GAD-7 scores in the GXDS group were considerably lower than those in the control group (P<0.05). Compared with the baseline, the total PHQ-9 scores of the experimental and control groups decreased by 3.97 and 1.18, respectively. The corrected mean difference between the two groups was -2.78 (95% CI: -3.47, -2.10; P<0.001). The total GAD-7 score in the GXDS group decreased by 3.48% compared with the baseline level, while that of the placebo group decreased by 1.13%. The corrected mean difference between the two groups was -2.35 (95% CI: -2.95, -1.76; P<0.001). The degree of improvement in SAQ score, SF-12 score, endothelin and high-sensitive C-reactive protein levels in the GXDS group were substantially superior than those in the placebo group, and the differences between the two groups were statistically significant (P<0.05). Similar results were obtained in the per protocol population analysis of 177 patients. Three cases of MACES were reported in this study (1 in the GXDS group and 2 in the placebo group), and no serious adverse events occurred.@*CONCLUSIONS@#GXDS can significantly alleviate depression and anxiety, relieve symptoms of angina, and improve quality of life in patients with CHD after PCI.

Panax Notoginseng Saponin Attenuates Gastric Mucosal Epithelial Cell Injury Induced by Dual Antiplatelet Drugs through COX and PI3K/Akt/ VEGF-GSK-3β-RhoA Network Pathway / 中国结合医学杂志

OBJECTIVE@#To elucidate the underlying mechanism of Panax notoginseng saponin (PNS) on gastric epithelial cell injury and barrier dysfunction induced by dual antiplatelet (DA).@*METHODS@#Human gastric mucosal epithelial cell (GES-1) was cultured and divided into 4 groups: a control, a DA, a PNS+DA and a LY294002+PNS+DA group. GES-1 apoptosis was detected by flow cytometry, cell permeability were detected using Transwell, level of prostaglandins E2 (PGE2), 6-keto-prostaglandin F1α (6-keto-PGF1α) and vascular endothelial growth factor (VEGF) in supernatant were measured by enzyme linked immunosorbent assay (ELISA), expression of phosphatidylinositide 3-kinase (PI3K), phosphorylated-PI3K (p-PI3K), Akt, phosphorylated-Akt (p-Akt), cyclooxygenase-1 (COX-1), cyclooxygenase-2 (COX-2), glycogen synthase kinase-3β (GSK-3β) and Ras homolog gene family member A (RhoA) were measured by Western-blot.@*RESULTS@#DA induced apoptosis and hyper-permeability in GES-1, reduced supernatant level of PGE2, 6-keto-PGF1α and VEGF (P<0.05). Addition of PNS reduced the apoptosis of GES-1 caused by DA, restored the concentration of PGE2, 6-keto-PGF1α and VEGF (P<0.05). In addition, PNS attenuated the alteration of COX-1 and COX-2 expression induced by DA, up-regulated p-PI3K/p-Akt, down-regulated RhoA and GSK-3β. LY294002 mitigated the effects of PNS on cell apoptosis, cell permeability, VEGF concentration, and expression of RhoA and GSK-3β significantly.@*CONCLUSIONS@#PNS attenuates the suppression on COX/PG pathway from DA, alleviates DA-induced GES-1 apoptosis and barrier dysfunction through PI3K/Akt/ VEGF-GSK-3β-RhoA network pathway.

Comparing the effects of depression, anxiety, and comorbidity on quality-of-life, adverse outcomes, and medical expenditure in Chinese patients with acute coronary syndrome / 中华医学杂志(英文版)

BACKGROUND@#Depression and anxiety have been correlated with elevated risks for quality-of-life (QOL), adverse outcomes, and medical expenditure in patients with acute coronary syndrome (ACS). However, the relevant data are lacking for Chinese ACS populations, especially regarding different effects of major depression, anxiety, and comorbidity. The objective of this study was to evaluate the dynamic changes of depression and/or anxiety over 12 months and examine the effects of depression, anxiety, and comorbidity on QOL, adverse outcomes, and medical expenditure in Chinese patients with ACS.@*METHODS@#For this prospective longitudinal study, a total of 647 patients with ACS were recruited from North China between January 2013 and June 2015. Among them, 531 patients (82.1%) completed 12-month follow-ups. Logistic regression model was utilized for analyzing the association of baseline major depression, anxiety, and comorbidity with 12-month all-cause mortality, cardiovascular events, QOL, and health expenditure.@*RESULTS@#During a follow-up period of 12 months, 7.3% experienced non-fatal myocardial infarction (MI) and 35.8% cardiac re-hospitalization. Baseline comorbidity, rather than major depression/anxiety, strongly predicted poor 12-month QOL as measured by short-form health survey-12 (odds ratio [OR]: 1.77, 95% confidence interval [CI]: 1.22-2.52, P = 0.003). Regarding 12-month non-fatal MI and cardiac re-hospitalization, baseline anxiety (OR: 2.83, 95% CI: 1.33-5.89, P < 0.01; OR: 4.47, 95% CI: 1.50-13.00, P < 0.01), major depression (OR: 2.58, 95% CI: 1.02-6.15, P < 0.05; OR: 5.22, 95% CI: 1.42-17.57, P < 0.03), and comorbidity (OR: 6.33, 95% CI: 2.96-13.79, P < 0.0001, OR: 14.08, 95% CI: 4.99-41.66, P < 0.0001) were all independent predictors, and comorbidity had the highest predictive value. Number of re-hospitalization stay, admission frequency within 12 months and medical expenditure within 2 months were the highest in patients with ACS with comorbidity.@*CONCLUSIONS@#Major depression and anxiety may predict 12-month non-fatal MI and cardiac re-hospitalization. However, comorbidity has the highest predictive value with greater medical expenditure and worse QOL in Chinese patients with ACS. And depression with comorbid anxiety may be a new target of mood status in patients with ACS.

Correlation between mucosa inflammation and abnormal drainaging state of maxillary sinus after endoscopic sinus surgery / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>This study is aimed to observe the natural draining state of maxillary sinus, to search for the key draining location (KDL) in the natural ostium, to investigate the relation between maxillary sinus draining and sinus inflammation, and to guide the treatment of maxillary sinus opening in endoscopic sinus surgery (ESS).</p><p><b>METHODS</b>Methylene blue was used as tracer agent in this study. Fifteen cases with or without light maxillary sinus inflammation (without any treatment) were selected to observe the natural draining state and the key draining location in maxillary sinus fontanel. Eighty-nine cases with chronic rhinosinusitis, but without nasal polyp, were selected, of which the maxillary sinus mucosa restored well 6 months after ESS, to observe the draining state and modes in maxillary sinus. All patients were followed up for 12 months to evaluate the inflammation state of mucosa, and to analyze the relations between the draining mode and mucosa inflammation.</p><p><b>RESULTS</b>The KDL for maxillary sinus was located in the posterior-inferior portion of the natural ostium, close to the attachment of caudal end of the uncinate process. The draining flowed along it from maxillary sinus to nasopharynx. After conventional transnasal endoscopic operation, 15 cases showed relatively normal drainage, others displayed abnormal state and mode,including reverse draining (maxillary sinus-ethmoid sinus) , multiphase draining (outflow from front, back and lower wall of natural ostium), draining failure (with cilia transporting function of maxillary epithelium mucosae), cistern like change (maxillary sinus and ethmoid sinus formed one operation cavity, secretion accumulated in maxillary sinus) and mucosa disfunction (loss of cilia transporting function of maxillary epithelium mucosae). Inflammation was observed in 33.7% of the patients 12 months after ESS, especially in those with mucosa disfunction, draining failure and reverse draining.</p><p><b>CONCLUSIONS</b>The KDL for maxillary sinus may be located in the posterior-inferior portion of the natural ostium, close to the attachment of caudal end of the uncinate process, and the drainage mode is not affected by gravity and posture. The KDL lesion after ESS results in abnormal draining of maxillary sinus, and excessively large maxillary sinus opening may aggravate mucosa inflammation of maxillary sinus. The abnormal draining state and mode may be related with the incidence of mucosa inflammation after operation. Preserving caudal end of uncinate process and avoiding injury of KDL would be beneficial to the restoration of mucosa and lessen the incidence of inflammation recurrence.</p>

Surgical treatment for bilateral traumatic optic neuropathy through intranasal endoscopic approach / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>This study was aimed to explore the necessity of nasal endoscopic operation for bilateral traumatic optic neuropathy.</p><p><b>METHODS</b>Four patients with complete blind resulted from traumatic impairment of bilateral optic nerves were selected to receive a combined treatment of nasal endoscopic optic nerve decompression (NEOND) with all-around medication.</p><p><b>RESULTS</b>The vision of all patients was improved except one who lost vision immediately after trauma. Thirty days after injury, patient 1 was treated with NEOND, and the vision of left eye was restored to 1.5, however, the vision of right side was just from light perception (LP) to hand motion (HM). Patient 2 was treated with NEOND 3 days after injury, and the vision was improved from LP to 0. 2 in left side, no change in right eye. The operation of patient 3 was performed 6 days after injury, but no improvement was observed in both visions. Patient 4 received NEOND 28 days after injury, the vision was improved in both sides with left eye from NLP to 0. 8 and right eye from NLP to 0.2.</p><p><b>CONCLUSIONS</b>NEOND can be regarded as an effective treatment for bilateral traumatic blindness, even delayed NEOND may be effective. Both gradual vision loss and residual vision should be the indications for an effective NEOND, but immediate blindness after injury might be the index for poor result of NEOND.</p>

Detection of specific IgE of anti-Staphylococcus aureus enterotoxins in nasal polyps and analysis theoretically about the superantigen hypothesis / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To search the evidence for the presence of superantigen of Staphylococcus aureus enterotoxin (SE) in the pathogenesis of nasal polyposis.</p><p><b>METHODS</b>In a cohort of population composed of 42 cases who belonged to three groups: nasal polyposis, simple chronic rhinosinusitis (CRS), and control group without any rhinopathy, detecting the specific IgE against SE-A and B (SEA and SEB), total IgE (TIgE), eosinophilic cationic protein (ECP) of the local mucosa by means of FRAST (UniCAP system), as well as the serum TIgE, and serum anti-SEA and SEB SIgE (only in 8 cases); meanwhile the secretion culture was performed for aerobic bacteria from the middle meatus.</p><p><b>RESULTS</b>There was no evidence to support that SE played as a superantigen in all mucosa samples (42 cases) and 8 cases serum samples out of the 42 patients. The range of TIgE in mucosa was 4.59 -70.21 kIU/2 mg tissue protein, the mean was (17.85 +/- 14.31) kIU/2 mg tissue protein; in serum the total IgE was 7.44 - 344.00 kIU/L, the mean was (88.65 +/- 80.03) kIU/L The positive culture of Staphylococcus aureus was obtained from only 3 cases from secretion of middle meatus (1 from nasal polyps, 2 from CRS). There was no significance statistically among the three groups on the tissue fluorescence value of SIgE for SE, the means of tissue TIgE and ECP.</p><p><b>CONCLUSIONS</b>No evidence was found to support the role of SE acting as a superantigen among our cases who did not have persistent asthma. It is suggested that further study and investigation is required to prove the superantigen Hypothesis in the pathogenesis of NPs.</p>

Semi-quantitative RT-PCR and immunohistochemical staining were used to examine P50 and P65 subunits of NF-KB expressions and activation in nasal mucosa. The correlation between activities of NF-KB P50 and P65 subunits and cytokine expression was evaluated.</p><p><b>RESULTS</b>IL-5, IL-6 and IL-8 levels in both AR and NAR groups were significantly increased (all P < 0.01 for AR group; P < 0.05, 0.05, 0.01, respectively, for NAR group, as compared with normal group), and the levels were much higher in AR group than that in NAR group (P < 0.01, 0.05, 0.01, respectively). The levels of P50 and P65 mRNA in both AR and NAR groups were enhanced (all P < 0.01 for AR group; all P < 0.01 for NAR group, as compared with normal group), and AR group had markedly greater P50 and P65 mRNA levels in comparison with NAR group (both P < 0.05). Immunohistochemical study revealed that nucleus-present rates of P50 and P65 in both AR and NAR groups were significantly higher than those of control group (all P < 0.01), and they were much greater in AR group as compared with NAR group (all P < 0.01). Pearson correlation analysis demonstrated that P50 and P65 nucleus-present rates were closely correlated with IL-6 and IL-8 levels, but not IL-5. The correlation coefficient was 0. 49 for P50 and IL-6, 0. 54 for P50 and IL-8, 0. 61 for P65 and IL-6, and 0.66 for P65 and IL-8 (all P < 0.01).</p><p><b>CONCLUSIONS</b>Activation of P50 and P65 subunits of NF-kappaB might be one of the mechanisms for induction of IL-6 and IL-8 expression in chronic sinusitis. Concomitance of allergic rhinitis with chronic sinusitis further increased activities of NF-kappaB subunits, and further elevated IL-6 and IL-8 expression. IL-5 expression was independent of NF-kappaB pathway in chronic sinusitis.</p>

Investigation of intranasal bacteriological character and pH value in patients with chronic rhinitis treated by Budesonide aqueous nasal spray / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To investigate the bacteriological character and pH value in nasal cavity and observe the efficacy following 8 week treatment with Budesonide aqueous nasal spray in chronic nonallergic rhinitis.</p><p><b>METHODS</b>Forty-two patients with chronic nonallergic rhinitis were treated with Budesonide aqueous nasal spray (256 microg once daily intranasal) for 8 weeks. Bacteriological character was measured before and 8 weeks after treatment All the swab specimens were obtained from the inferior meatus, bacteriologic outcome was determined by general cultures. Nasal pH value was measured by using a probe sited under the inferior turbinate before and after treatment. Efficacy was evaluated by measurement of nasal symptom scores and sign scores before and 8 weeks after treatment.</p><p><b>RESULTS</b>The bacterial growth was present in 37 of 42 cases (88%) before the treatment (group 1), including 53 aerobic bacteria. The bacterial growth was present in 38 of 42 cases (90.47%) 8 weeks after treatment (group 2), including 46 aerobic bacteria. There was no significant difference in the bacterial distribution between group 1 and group 2 (chi2 = 0.416, P > 0.05). Budesonide aqueous nasal spray reduced pH value from 7.90 +/- 0.39 to 7.70 +/- 0.23 (t = 2.72, P < 0.05). All the parameters of symptoms were improved after treatment, including nasal obstruction, nasal secretions, itchy feeling of the nose, closed rhinolalia and headache.</p><p><b>CONCLUSIONS</b>Glucocorticoid aqueous nasal spray could be used safely for eight weeks and does not increase the risk of aerobes and fungi infection and reduce the pH in chronic nonallergic rhinitis. It is effective in relieving symptoms of patients with chronic nonallergic rhinitis.</p>
