[Prediction of pathological remission of head and neck squamous cell carcinoma patients after neoadjuvant immunochemotherapy and construction of clinical model based on clinical features and inflammatory markers].

Objective: To analyze the potential clinical biological factors influencing the major pathological response (MPR) to neoadjuvant immunochemotherapy in patients with resectable head and neck squamous cell carcinoma (HNSCC). Methods: This retrospective study enrolled patients with resectable HNSCC who underwent neoadjuvant immunochemotherapy at Sun Yat-sen University Cancer Center from June 1, 2019 to December 31, 2021. Binary logistic regression was used to analyze the correlation between clinical characteristics, inflammatory markers and MPR, and a nomogram model was constructed. The calibration curve and decision curve analysis were used to verify the predictive ability and accuracy of the nomogram model. Results: A total of 173 patients were included in the study, with 141 males and 32 females, aged from 22 to 83 years. After pathological assessment, the patients were divided into two groups: MPR group (108 cases) and non MPR group (65 cases). Logistics regression analysis indicated that the patients with HPV+oropharyngeal cancer, partial response or complete response by imaging assessment, low pre-treatment platelet/lymphocyte ratio, low pre-treatment C reactive protein/albumin ratio and lower pre-and post-treatment C reactive protein/albumin ratio difference were more likely to have MPR (all P<0.05). Nomogram model was constructed based on the above factors, with a C-index of 0.826 (95%CI: 0.760-0.892), and the calibration curve and decision curve analysis confirmed the prediction accuracy of the model. Conclusion: This study shows that many factors are related to MPR of patients with resectable HNSCC receiving neoadjuvant immunochemotherapy and the constructed nomogram model helps to develop personalized treatment strategies for the patients.

Anomalous staged hot-electron acceleration by two-plasmon decay instability in magnetized plasmas.

We present a staged hot-electron acceleration mechanism of the two-plasmon decay (TPD) instability in the transverse magnetic field under the parameters relevant to inertial confinement fusion experiments. After being accelerated by the forward electron plasma wave (FEPW) of TPD, the hot-electrons can be anomalously accelerated again by the backward electron plasma wave (BEPW) of TPD and then obtain higher energy. Moreover, the surfatron acceleration mechanism of TPD in the magnetic field is also confirmed, the electrons trapped by the TPD daughter EPWs are accelerated in the direction along the wave front. Interestingly, the velocity of electrons accelerated by surfing from the FEPW is quite easily close to the BEPW phase velocity, which markedly enhances the efficiency of the staged acceleration. The coexistence of these two acceleration mechanisms leads to a significant increase of energetic electrons generated by TPD in the magnetic field. Meanwhile the EPWs are dissipated, TPD instability is effectively suppressed, and the laser transmission increases.

Kinetic model and Vlasov simulation verification of two-ion decay instability.

A kinetic theory is developed to describe the longitudinal decay of two-ion decay (TID): The pump ion-acoustic wave (IAW) decays into two daughter IAWs with a longer wavelength. The instability growth rate and threshold are given by the theory. Both the simulations of full kinetic Vlasov and hybrid Vlasov (kinetic ions and Boltzmann electrons) are employed to verify the theory and have a high quantitative agreement with the theory for 8≤ZT_{e}/T_{i}≤15, where Z is the ion charge number and T_{i}(T_{e}) is the ion (electron) temperature. The kinetic model developed here solves a long-standing problem that the simple fluid theory underestimates growth rate by a factor of 2∼3. Also, a reasonable explanation is given to the typical characteristics of TID that the dependence curves of subharmonic growth rate γ and wave number k.

[Clinical application of a classification based on crucial curvature of coronal imbalance in degenerative lumbar scoliosis].

Objective: To present efficacy of clinical application of a classification based on crucial curvature of coronal imbalance in degenerative lumbar scoliosis (DLS). Methods: A case series study. Clinical data of 61 cases (8 males, 53 females) who underwent posterior correction surgery for DLS from January 2019 to January 2021 were retrospectively analyzed. The mean age was (71.7±6.2) years (ranged 60-82 years). According to the direction of C7 plumb line (C7PL) deviated from central sacral vertical line (CSVL) and orientation of L4 coronal tilt, the author determined which one was the crucial curve. If C7PL deviated from CSVL in the same direction as concave side of the thoracolumbar curve and L4 coronally tilts opposite direction of C7PL deviates from CSVL, then the crucial curve was thoracolumbar curve (type 1). On the contrary, if C7PL deviated from CSVL in the same direction as concave side of the lumbosacral curve and L4 coronally tilts consist with direction of C7PL deviates from CSVL, then the crucial curve was lumbosacral curve (type 2). According to absolute value of coronal balance distance (|CBD|), each type of patients was divided into two groups, respectively, namely coronal balance (CB) (|CBD|≤3 cm) and coronal imbalance (CIB) (|CBD|>3 cm). Changes of Cobb angles of thoracolumbar curve and lumbosacral curve and CBD were recorded and analyzed. Results: The rate of preoperative CIB was 55.7% (34/61) in all the patients. Of the patients, 23 cases were classified as type 1 and 38 cases as type 2. The rate of preoperative CIB was 34.8% (8/23) in type 1 patients and 68.4% (26/38) in type 2. The rate of postoperative CIB was 27.9% (17/61) in all the patients, with 13.0% (3/23) in type 1 and 36.8% (14/38) in type 2. The |CBD| of CB group in type 1 patients decreased from (2.6±1.4) cm before the operation to (1.5±1.0) cm after (P=0.015); and the correction rate of thoracolumbar curve (68.8%±18.4%) was significantly higher than that of lumbosacral curve (34.5%±23.9%) (P=0.005). The |CBD| of CB group in type 2 patients decreased from (2.6±3.0) cm before the operation to (1.6±1.2) cm after (P=0.027); the correction rate of lumbosacral curve (71.3%±18.6%) was higher than that of thoracolumbar curve (57.3%±21.1%), but the difference was not statistically significant (P=0.546). There was no significant difference in |CBD| of CIB group in type 2 patients before and after the operation (P=0.222); the correction rate of lumbosacral curve (38.3%±14.8%) was significantly lower than that of thoracolumbar curve (53.6%±16.0%) (P=0.001). There was a correlation between the change of CBD (3.8±1.5) cm and the difference in correction rate between thoracolumbar and lumbosacral curve (32.3%±19.6%) in CB group in type 1 patients after surgery (r=0.904, P<0.001). There was a correlation between the change of CBD (1.9±2.2) cm and the difference in correction rate between lumbosacral and thoracolumbar curve (14.0%±26.2%) in CB group in type 2 patients after surgery (r=0.960, P<0.001). Conclusion: Clinical application of a classification based on crucial curvature of coronal imbalance in DLS is satisfactory, and its combination with matching correction can effectively prevent the occurrence of coronal imbalance after spinal correction surgery.

[Association between obesity and the prevalence of type 2 diabetes mellitus among Chinese adults aged 18-65 years in 15 provinces in 2018].

Objective: To analyze the association between different types of obesity, BMI, and waist circumference (WC) and the risk of type 2 diabetes mellitus (T2DM) in Chinese adults. Methods: Based on the China Health and Nutrition Survey data in 2018, different types of obesity were defined across different BMI and WC combinations based on Criteria of weight for adults (WS/T 428-2013), including non-obesity, simple general obesity, simple central obesity, and complex obesity. The associations of different types of obesity, BMI, and WC with T2DM risk were explored using two-level mixed-effects logistic regression and restricted cubic spline models. Results: A total of 7 030 subjects aged 18-65 were included in this study. The prevalence of general obesity and central obesity were 16.29% (502/3 082), 42.28% (1 303/3 082) in males, and 14.41% (569/3 948), 37.87% (1 495/3 948) in females. The prevalence of complex obesity was 14.70% and 12.97% in males and females, respectively. The prevalence of T2DM was 11.28% in participants, and the prevalence in complex obesity (18.98%, 22.07%) was higher than in simple central obesity (16.24%, 15.26%) and non-obesity (9.65%, 5.18%) in males and females, respectively. Multilevel regressions showed that males with simple central obesity and complex obesity had 1.61 (95%CI: 1.24-2.08) and 2.11 (95%CI: 1.56-2.86) times the odds of T2DM, respectively, as compared with the non-obesity; and the odds of T2DM in females were 2.70 (95%CI: 1.16-6.28) times for simple general obesity, 2.62 (95%CI: 2.01-3.40) times for simple central obesity, and 4.47 (95%CI: 3.35-5.98) times for complex obesity. A nearly linear positive association was observed between BMI and T2DM risk. WC was also positively associated with T2DM risk and a non-linearly increased risk in females (P for non-linear=0.024). The risk of T2DM increased when BMI ≥22.5 kg/m2 and 23.0 kg/m2, WC ≥85.0 cm and 80.0 cm in males and females, respectively. Conclusions: Complex obesity adults are more likely to suffer from T2DM. The risk of T2DM increases significantly when BMI is at the normal high values and waist circumference at the stage of pre-central obesity.

[The role of preventive pancreatic duct stent placement in preventing acute pancreatitis after endoscopic retrograde cholangiopancreatography].

The aim of this study was to investigate the preventive effect of pancreatic duct stent on acute pancreatitis after endoscopic retrograde cholangiopancreatography. A retrospective analysis of the case data of patients who first underwent endoscopic retrograde cholangiopancreatography for choledocholithiasis in the Beijing Friendship Hospital from January 2015 to December 2019 for 5 years. According to whether the pancreatic duct stent was indwelled during the operation, they were divided into pancreatic duct stent group (147 cases) and non-indwelling pancreatic duct stent group (192 cases). The incidence of acute pancreatitis after endoscopic retrograde cholangiopancreatography was compared between the two groups according to COTTON criteria. Independent sample t test, Pearson Chi-square test (χ2) and Fisher's exact test were used to compare groups' differences. There were 2 cases of acute pancreatitis in the pancreatic duct stent group, all of which improved after 48 hours. There were 22 cases of acute pancreatitis in the non-indwelling pancreatic duct stent group, of which 20 cases improved within 48 hours, and the other 2 cases had severe pancreatitis, which improved and discharged after 30 days of treatment. There was significant difference in the incidence of acute pancreatitis between the pancreatic duct stenting group (1.4%) and the group without placement of pancreatic duct stents (11.5%) (χ²=12.905,P<0.001). In conclusion, Pancreatic duct stent may be an effective method to prevent PEP.

Polarization conversion in the caviton driven by linearly polarized lasers.

In one-dimensional particle-in-cell simulations of a plasma irradiated by linearly polarized lasers from both sides of boundaries, it is found that there is an appreciable growth of the electromagnetic field in cavitons in the transverse direction perpendicular to the direction of polarization, which indicates the polarization conversion of the electromagnetic field in cavitons. This paper demonstrates the mechanism of this phenomenon based on parametric resonance induced by ponderomotive force with twice the frequency of the electromagnetic radiation in the caviton. We develop a theoretical model and verify it with simulation results. This phenomenon contributes to the heating and acceleration of particles and traps more EM energy in cavitons.

[Impact of inflammatory reaction levels and culprit plaque characteristics on preprocedural thrombolysis in myocardial infarction flow grade in patients with ST-segment elevation myocardial infarction].

Objective: To determine the impact of inflammatory reaction levels and the culprit plaque characteristics on preprocedural Thrombolysis in Myocardial Infarction (TIMI) flow grade in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). Methods: The is a retrospective study. A total of 1 268 STEMI patients who underwent pre-intervention optical coherence tomography (OCT) examination of culprit lesion during emergency PCI were divided into 2 groups by preprocedural TIMI flow grade (TIMI 0-1 group (n =964, 76.0%) and TIMI 2-3 group (n =304, 24.0%)). Baseline clinical data of the 2 groups were collected; blood samples were collected for the detection of inflammatory markers such as high sensitivity C-reactive protein (hsCRP), myocardial injury marker, blood lipid, etc.; echocardiography was used to determine left ventricular ejection fraction; coronary angiography and OCT were performed to define the lesion length, diameter stenosis degree of the infarct-related arteries, presence or absence of complex lesions, culprit lesion type, area stenosis degree and vulnerability of culprit plaques. Multivariable logistic regression analysis was performed to identify independent correlation factors. The receiver operating characteristic (ROC) curve of continuous independent correlation factors was analyzed, and the best cut-off value of TIMI 0-1 was respectively determined according to the maximum value of Youden index. Results: The mean age of 1 268 STEMI patients were (57.6±11.4) years old and 923 cases were males (72.8%). Compared with TIMI 2-3 group, the patients in TIMI 0-1 group were older and had higher N-terminal-pro-B-type natriuretic peptide level, lower cardiac troponin I (cTnI) level, lower left ventricular ejection fraction, and higher hsCRP level (5.16(2.06, 11.78) mg/L vs. 3.73(1.51, 10.46) mg/L). Moreover, the hsCRP level of patients in TIMI 0-1 group was higher in the plaque rupture subgroup (all P<0.05). Coronary angiography results showed that compared with TIMI 2-3 group, the proportion of right coronary artery (RCA) as the infarct-related artery was higher, the angiographical lesion length was longer, minimal lumen diameter was smaller, and diameter stenosis was larger in TIMI 0-1 group (all P<0.05). The prevalence of plaque rupture was higher (75.8% vs. 61.2%) in TIMI 0-1 group. Plaque vulnerability was significantly higher in TIMI 0-1 group than that in TIMI 2-3 group with larger mean lipid arc (241.27°±46.78° vs. 228.30°±46.32°), more thin-cap fibroatheroma (TCFA, 72.4% vs. 57.9%), more frequent appearance of macrophage accumulation (84.4% vs. 70.7%) and cholesterol crystals (39.1% vs. 25.7%). Minimal flow area was smaller [1.3(1.1-1.7)mm2 vs. 1.4(1.1-1.9)mm2, all P<0.05] and flow area stenosis was higher (78.2%±10.6% vs. 76.3%±12.3%) in TIMI 0-1 group. Multivariable analysis showed that mean lipid arc>255.55°, cholesterol crystals, angiographical lesion length>16.14 mm, and hsCRP>3.29 mg/L were the independent correlation factors of reduced preprocedural TIMI flow grade in STEMI patients. Conclusions: Plaque vulnerability and inflammation are closely related to reduced preprocedural TIMI flow grade in STEMI patients.

[Meta-analysis of the effects of triamcinolone acetonide alone and in combination with 5-fluorouracil for treating keloids].

Objective: To compare the efficacy and safety of triamcinolone acetonide (TA) alone and in combination with 5-fluorouracil (5-FU) for treating keloids using meta-analysis. Methods: Databases including PubMed, Embase, and Cochrane Library were retrieved with the search terms of " triamcinolone acetonide, 5-fluorouracil, glucocorticoid, fluorouracil, keloid, scar, TAC, 5-FU, hypertrophic scar " and databases including Chinese Journal Full-Text Database, Chinese Biomedical Database, and Wanfang Data were retrieved with the search terms of ",, 5-,," in Chinese to obtain the publicly published randomized controlled trials about the effects of TA alone and in combination with 5-fluorouracil for treating keloids from the establishment of each database to august 2019. The outcome indexes included effective proportion of treatment, incidence proportion of adverse reactions, and recurrence proportion of keloids. RevMan 5.3 and Stata 14.0 statistical software were used to conduct a meta-analysis of eligible studies. Results: A total of 1 326 patients with keloids were included in 14 studies, including 668 patients in TA+ 5-fluorouracil group whose keloids were injected with TA and 5-fluorouracil and 658 patients in TA alone group whose keloids were injected with TA alone. A total of 7 articles achieved 1 to 3 points in modified Jadad score, while 7 articles achieved 4 to 7 points in modified Jadad score. Patients in TA+ 5-fluorouracil group had a higher effective proportion of treatment than that of TA alone group (relative risk=1.28, 95% confidence interval=1.16-1.41, P<0.01). Subgroup analysis showed that the quality of the included literature and ethnic factors might be the source of heterogeneity in effective proportion of treatment. Patients in TA+ 5-fluorouracil group had a lower incidence proportion of adverse reactions than that of TA alone group (relative risk=0.44, 95% confidence interval=0.25-0.75, P<0.01). Patients in TA+ 5-fluorouracil group had a lower recurrence proportion of keloids than that of TA alone group (relative risk=0.25, 95% confidence interval=0.14-0.44, P<0.01). There was no publication bias in incidence proportion of adverse reactions (P>0.05), while the effective proportion of treatment and recurrence proportion of keloids had publication bias (P<0.05). Conclusions: TA combined with 5-fluorouracil is more effective than TA alone for treating keloids, with less incidence of adverse reactions and recurrence.

[A study on the targeted nanoparticles of isosorbide mononitrate on reducing the levels of inflammatory factors in rabbit models of rhinosinusitis].

Objective: To investigate the effect of isosorbide mononitrate (ISMN) targeted nanoparticles on inflammatory factors of sinusitis by establishing a rabbit model of rhinosinusitis. Methods: Thirty healthy rabbits, male and female, weighing 2.5-3.5 kg, were randomly divided into 6 groups with 5 rabbits in each group. Group A was the control group. The model of rabbit sinusitis was established in group B to F, and CT was used to confirm the model was successful. After placing tubes into the maxillary sinus in the group C to F, saline, 45 mg/ml ISMN, 45 mg/ml ISMN nanoparticles and 45 mg/ml ISMN targeted nanoparticles were used to wash the maxillary sinus, respectively. Blood samples were collected from the ear vein of rabbits on day 7, 14, 21, 28, 35 and 42 after modeling respectively. Changes in the expression levels of inflammatory factors in rabbits during the modeling process and after drug washing were detected by ELISA. After the drug intervention, the maxillary sinus mucosa was taken for real-time quantitative PCR to detect the changes in the mRNA level of inflammatory factors. SPSS 22.0 software was used to process the data. Results: Rabbit model of sinusitis was successfully established. ELISA showed that after the action of ISMN targeted nanoparticles of 1 week (42th day after modeling), the levels of (interleukin, IL) 4, IL-8, IL-17A and interferon γ (IFN-γ) in the blood were lower compared with that of 35th day after modeling, the difference was statistically significant (5.57±1.20 vs 19.73±0.68, 66.41±11.87 vs 154.68±13.13, 17.96±1.87 vs 28.23±0.80, 53.56±5.66 vs 111.93±7.29, all P<0.05). Compared with the ISMN nanoparticles and ISMN, the ISMN targeted nanoparticles reduced the levels of IL-4, IL-8, IL-17A and IFN-γ more obviously, the differences were statistically significant (13.26±1.43 vs 8.81±1.33 vs 7.14±2.16, 89.47±17.80 vs 41.07±7.77 vs 15.84±3.72, 10.28±2.07 vs 3.06±1.62 vs 1.82±0.90, 62.16±6.18 vs 35.12±4.62 vs 27.89±10.18, all P<0.05). Real-Time PCR showed that after the flushing of ISMN targeted nanoparticles, the levels of IL-4, IL-8, IL-17A and IFN-γ mRNA were lowest compared with that of the model group, ISMN nanoparticles and ISMN group. Conclusion: ISMN targeted nanoparticles can reduce the level of inflammatory factors in rabbit sinusitis model.

Analyses of microRNA166 gene structure, expression, and function during the early stage of somatic embryogenesis in Dimocarpus longan Lour.

MicroRNA166 (miR166) contributes to post-transcriptional regulation by binding the mRNAs of HD-ZIP III genes, which affects plant growth and development. The structural characteristics, expression, and functions of miR166 genes during the early somatic embryogenesis stage in Dimocarpus longan remain unknown. We isolated the transcripts of pri-miR166 S78 with two transcription initiation sites (TSSs) and pri-miR166 S338 with one TSS. These sequences contain potential smORFs and encode different miRNA peptides (miPEPs). Additionally, their promoters contain cis-acting elements responsive to diverse stimuli. The pre-miR166 S78 and pre-miR166 S338 expression levels were up-regulated in response to 2,4-D, abscisic acid, and ethylene. Although the expression patterns induced by hormones were similar, there were differences in the extent of the response, with pre-miR166 S338 more responsive than pre-miR166 S78. Thus, miRNA transcription and maturation are not simply linearly correlated. Moreover, pre-miR166 S78 and pre-miR166 S338 expression levels were down-regulated, whereas ATHB15 (target gene) expression was up-regulated, from the longan embryonic callus to the globular embryo stages. These results are indicative of a negative regulatory relationship between miR166 and ATHB15 during the early somatic embryogenesis stage in longan. At the same stages, miR166a.2-agomir, miR166a.2-antagomir, and miPEP166 S338 increased or decreased the expression of miR166a.2 and ATHB15, but with no consistent patterns or linear synchronization, from which we've found some reasons for it.

[The etiological analysis of 260 hospitalized cases with bilateral adrenal lesions].

Objective: To summarize the etiologies of bilateral adrenal lesions and the changes of the disease profile in hospitalized patients. Methods: Bilateral adrenal lesion screening was conducted in all patients admitted to Peking University Third Hospital from 1994 to 2017. The etiologies and disease profiles of bilateral adrenal lesions were retrospectively analyzed. Results: A total of 260 patients with bilateral adrenal lesions were included in the study. There were 146 males and 114 females with a mean age of (55.4±16.2) years. The most common adrenal lesion was bilateral adrenal hyperplasia (75 cases, 28.8%), followed by bilateral adrenal adenomas (71 cases, 27.3%), metastatic carcinoma (51 cases, 19.6%), discordant bilateral adrenal lesions (27 cases, 10.4%), bilateral pheochromocytomas (13 cases, 5.0%), and others. The clear data of endocrine function evaluation could be found in 184 patients. Among them, 111 cases (60.3%) were nonfunctioning lessions, 34 cases (18.5%) with primary aldosteronism, 15 cases (8.1%) with pheochromocytoma, 13 cases (7.1%) with congenital adrenal hyperplasia, 6 cases (3.3%) with primary hypoadrenocorticism, and 5 cases (2.7%) with Cushing syndrome. Using every 8 years as a period of time, the number of hospitalized patients with bilateral adrenal lesions increased with years in three periods (8, 41 and 211 cases, respectively). Conclusions: The most common cause of bilateral adrenal lesions is adrenal hyperplasia in the hospitalized patients. More than half of bilateral adrenal lesions are nonfunctioning. In functional bilateral lesions, primary aldosteronism and pheochromocytoma account for a large proportion.

Influence of tool edge waviness on the diffraction effect of diamond-turned optics: theoretical simulation and experimental validation.

In this work, the influence of tool edge waviness on the diffraction effect of diamond-turned optics is simulated theoretically and further validated experimentally. In simulation, a 3D surface topography model with consideration of the influence of tool edge waviness is established, in which the variation of tool edge profile is estimated by a linear model in relation to the cutting distance. The results show that the diffraction effect represented in simulation is consistent with the experimental observation. With the deterioration of tool edge waviness, the diffraction efficiency of the specular light decreases, but the high-order diffracted light intensively distributes in the horizontal direction on the receiving screen. Such observation can be attributed to the subgrating effect induced by the periodic duplication of the tool edge profile on the machined surface, which heavily depends on the deterioration of tool edge waviness. Finally, a waviness-controlled diamond tool is recommended to finish a diffraction-free optics by the diamond turning process. Moreover, the diffraction effect can also be employed to monitor the dynamic wear of the cutting tool in diamond turning.

The down-regulation of long non-coding RNA LINC01088 is associated with the poor prognosis of epithelial ovarian cancer patients.

OBJECTIVE: Long intergenic non-coding RNA 1088 (LINC01088) has been suggested to act as a tumor suppressor in epithelial ovarian cancer (EOC); however, the prognostic role of LINC01088 has not been evaluated in cancer patients. This study aimed to investigate the expression of LINC01088 in EOC, along with evaluating its clinical-pathological and prognostic importance. PATIENTS AND METHODS: A bioinformatics tool (GEPIA) was used to screen the dysregulated lncRNAs. Quantitative Real-time PCR (qRT-PCR) was used to measure expression level of LINC01088 in EOC tumor samples and adjacent non-tumor tissues. Then, the association between LINC01088 expression and pathological parameters were further evaluated. Overall survival (OS) was estimated using the Kaplan-Meier method, and the differences in survival were compared using the log-rank test. Univariate and multivariate analysis were performed using the Cox proportional hazard analysis. RESULTS: We found that LINC01088 expression was significantly down-regulated in EOC tissues via "GEPIA". Then, the results of RT-PCT confirmed that the expression levels of LINC01088 were significantly lower in EOC tissues compared to adjacent noncancerous tissues (p < 0.01). Interestingly, lower LINC01088 expression levels were associated with FIGO stage (p = 0.000), grade (p = 0.003) and distant metastasis (p = 0.006). Moreover, Kaplan-Meier analysis indicated that patients with low LINC01088 expression had a poor overall survival (p = 0.0013). Finally, univariate and multivariate analysis show that LINC01088 expression is an independent predictor for overall survival. CONCLUSIONS: Low LINC01088 expression was associated with the progression of EOC and could serve as a potential independent prognostic biomarker for patients with EOC.

[Clinical analysis of individualized nasal cavity ventilation expansion techniques for treatment of OSAHS patients].

Objective:To investigate efficacy of individualized nasal cavity ventilation expansion techniques for OSAHS patients with nasal obstruction. Method:One hundred and twelve OSAHS patients with nasal obstruction were included in this study. Nasal cavity ventilation expansion techniques were performed. Every patient took the examination of acoustic rhinometry, nasal respiration volume, rhinomanometry and polysomnography, and filled VAS of nasal obstruction and Epworth Sleep Scores(ESS) before surgery and three months after surgery. Result:Follow-up was for 6－12 months. Of all the patients, 39 cases were cured, 37 cases were remarkably improved, 21 cases were effective, and 15 cases were of no effect, respectively. Compared with pre-operative examination data in all OSAHS patients, nasal ventilation was markedly improved, the ESS was significantly decreased, the AHI was significantly decreased, LSaO2 and MSaO2 were significantly increased, and sleep structure did not change significantly in all OSAHS patients 6 month after nasal surgery. Conclusion:Individualized nasal cavity ventilation expansion techniques is an effective treatment for OSAHS patients with nasal obstruction，improves the safety of patients with UPPP surgery, and the tolerability of CPAP in some patients with ineffective surgery.
