Effects of Three Different Heating Devices on Patients Undergoing Surgery: A Network Meta-Analysis.

PURPOSE: Perioperative hypothermia is a common anesthesia-related complication that can result in negative outcomes. Intraoperative active heating can positively impact these outcomes. Therefore this study aimed to investigate the effectiveness of three common heating devices for controlling hypothermia, improving thermal comfort, and reducing anesthesia recovery time. DESIGN: Systematic review and meta-analysis. METHODS: Seven electronic literature databases were searched from the inception date of the databases to March 18, 2022. RevMan 5.4 and Stata 15.1 were used to perform meta-analyses on the obtained data, and the Cochrane Evaluation Manual was used for quality risk assessment of the included studies. FINDINGS: A total of 18 studies involving 1,511 patients undergoing surgery using heating devices were included. In this meta-analysis, a ranking method known as the Surface Under the Cumulative Ranking Curve (SUCRA) was used. SUCRA provides a numerical measure of the effectiveness of treatments, with higher values indicating superior efficacy. Findings demonstrated that the concurrent use of three heating devices led to an elevation in core body temperatures (SUCRA = 69.2%) and enhanced delayed recovery (SUCRA = 88.6%) as compared to the application of a single device. Furthermore, for thermal comfort, the employment of heating blankets proved to be the most effective (SUCRA = 87.8%). CONCLUSIONS: This study showed the core body temperatures and reductions in delayed recovery were greater when three heating devices were used together as compared to use one of them alone. Heating blankets was the most effective option for improving the thermal comfort of patients. Thus, clinicians should opt for appropriate heating equipment according to the type of surgery and the characteristics and needs of patients. The choice of appropriate heating equipment will ensure surgical safety, improve patient comfort, and reduce surgical risks.

[Effects of modified proper digital artery island flap in repairing complex fingertip defects].

Objective: To investigate the surgical method and clinical effects of the modified proper digital artery island flap in repairing complex fingertip defects. Methods: A retrospective observational study was conducted. From January 2017 to December 2021, 15 patients (15 fingers) with complex fingertip defects, involving the pulp, nail bed, and lateral wall of the nail, who met the inclusion criteria were admitted into General Hospital of Northern Theater Command, including 11 males and 4 females, aged from 18 to 55 years. The area of the post debridement wound was from 2.5 cm×2.0 cm to 3.5 cm×3.5 cm, and all the wounds were repaired by using modified proper digital artery island flap (including 3 parts: main flap, tongue-shaped flap, and triangular flap), of which the main flap was used to cover the finger pulp defect, the tongue-shaped flap was used to cover the nail bed and the nail lateral wall defect, and the triangular flap was inserted into the edge of the finger pulp wound to cover the vessel pedicle. The range of the flap ranged from 3.0 cm×2.0 cm to 4.5 cm×3.0 cm. The wound at the donor site was repaired with full-thickness skin graft of the groin, and the donor site of the skin graft was sutured directly. After operation, the survival of the flap and skin graft as well as and the appearance of the affected finger were observed. During the follow-up, the fingertip morphology of the affected finger was observed, two-point discrimination distance of the affected finger pulp was measured, and the patients' satisfaction with the efficacy (including very satisfied, satisfied, and dissatisfied) was asked, and the affected finger function was evaluated by the total active movement (TAM) system evaluation standard recommended by American Academy for Surgery of Hand. Results: After operation, the main flaps and skin grafts in 15 patients all survived; but the incision at the edge of tongue-shaped flap in one patient healed poorly, and one patient developed venous stasis at the distal end of the tongue-shaped flap; the triangular flap at the pedicle was slightly bloated in the early postoperative period and became smooth after 2 to 3 months. Overall, two patients developed subcutaneous hematoma in their flaps. All the complications were healed by appropriate dressing change, suture removal, or compression bandaging. After operation, the appearance of the flap was full and formed a prominent fingertip shape. During the follow-up of 6 months to 5 years, the fingertips of the affected fingers were prominent and full; the two-point discrimination distance of the affected finger pulp was (8.6±1.4) mm; 8 patients were very satisfied with the efficacy, 6 patients were satisfied, and one patient was dissatisfied; the functional assessment of the affected fingers were all excellent. Conclusions: The modified proper digital artery island flap can repair complex fingertip defects involving the pulp, nail bed, and lateral wall of the nail. The operation is simple, and the shape and function of the fingertip are good after surgery.

[Correlation analysis of age and microbial characteristics in saliva and feces of high-risk population of upper gastrointestinal cancer].

Objective: To explore the correlation between age and diversity and microbial composition in saliva and feces microbiota in high-risk population of upper gastrointestinal cancer. Methods: Based on the national project on early diagnosis and early treatment of upper gastrointestinal cancer, 38 participants were enrolled in Linzhou in Henan province in August 2019. The participant information was collected by questionnaire. Saliva and feces specimens were collected from each participant for 16S rRNA sequencing and bioinformatics analysis. Spearman rank correlation was used to analyze the correlation between age and α diversity (Observed ASVs and Shannon index) and relative abundance of microbiota (phyla, genera, and species) in saliva and feces. Results: The median age (age range) of 38 participants was 54 (43-60) years old, and there were 16 males (42.1%). The Observed ASVs of saliva was negatively correlated with age (rs=-0.35, P<0.05), but the observed ASVs of feces was not correlated with age. In saliva, the relative abundance of Treponema (rs=‒0.44, P<0.05), Alloprevotella (rs=‒0.42, P<0.05), and Porphyromonas (rs=‒0.41,P<0.05) were significantly negatively correlated with age. At the species level, the relative abundance of Porphyromonas endodontalis, Alloprevotella tannerae, Haemophilus influenza, Moraxella bovoculi, Prevotella sp.oral clone ID019, and Prevotella sp.oral clone ASCG10 in saliva were significantly negatively correlated with age, and the rs values were -0.50, -0.40, -0.38, -0.35, -0.33 and -0.33 (P<0.05), respectively. In feces, the relative abundance of Enterobacteria (rs=-0.35, P<0.05), Escherichia (rs=-0.33, P<0.05), and Bifidobacteria (rs=0.33, P<0.05) were correlated with age. At the species level, the relative abundance of Romboutsia sedimentorum, Citrobacter murliniae, and bacteroides uniformis in feces were correlated with age, and the rs values were -0.42, -0.37 and 0.36 (P<0.05), respectively. Conclusion: Age of the high-risk population of upper gastrointestinal cancer is correlated with the relative abundance of microbiota in saliva and feces.

Chemical constituents of Aglaia elaeagnoidea and Aglaia odorata and their cytotoxicity.

Two new rocaglamides, 8b-O-5-oxohexylrocaglaol (1) and elaeagnin (2), together with twelve known compounds, were isolated from the bark of Aglaia elaeagnoidea and the whole tree of A. odorata. Their structures were determined using spectroscopic methods, mainly 1D and 2D NMR. Cytotoxic activity against HepG2 human liver cancer cells of the isolated compounds was evaluated in vitro using the SRB assay. Three rocaglamide derivatives, dehydroaglaiastatin (13), 8b-O-5-oxohexylrocaglaol (1) and rocaglaol (5), exhibited significant effects with IC50 values of 0.69, 4.77 and 7.37 µM, respectively.

[Long-term efficacy and safety of simultaneous integrated boost radiotherapy in non-operative esophageal squamous cell carcinoma: a multicenter retrospective data analysis (3JECROG R-05)].

Objective: To analyze the survival benefits and treatment related toxic effects of simultaneous integrated boost intensity-modulated radiotherapy (SIB-RT) for non-operative esophageal squamous cell carcinoma patients. Methods: The data of 2 132 ESCC patients who were not suitable for surgery or rejected operation, and underwent radical radiotherapy from 2002 to 2016 in 10 hospitals of Jing-Jin-Ji Esophageal and Esophagogastric Cancer Radiotherapy Oncology Group (3JECROG) were analyzed. Among them, 518 (24.3%) cases underwent SIB (SIB group) and 1 614 (75.7%) cases did not receive SIB (No-SIB group). The two groups were matched with 1∶2 according to propensity score matching (PSM) method (caliper value=0.02). After PSM, 515 patients in SIB group and 977 patients in No-SIB group were enrolled. Prognosis and treatment related adverse effects of these two groups were compared and the independent prognostic factor were analyzed. Results: The median follow-up time was 61.7 months. Prior to PSM, the 1-, 3-, and 5-years overall survival (OS) rates of SIB group were 72.2%, 42.8%, 35.5%, while of No-SIB group were 74.3%, 41.4%, 31.9%, respectively (P=0.549). After PSM, the 1-, 3-, and 5-years OS rates of the two groups were 72.5%, 43.4%, 36.4% and 75.3%, 41.7%, 31.6%, respectively (P=0.690). The univariate survival analysis of samples after PSM showed that the lesion location, length, T stage, N stage, TNM stage, simultaneous chemoradiotherapy, gross tumor volume (GTV) and underwent SIB-RT or not were significantly associated with the prognosis of advanced esophageal carcinoma patients who underwent radical radiotherapy (P<0.05). Cox model multivariate regression analysis showed lesion location, TNM stage, GTV and simultaneous chemoradiotherapy were independent prognostic factors of advanced esophageal carcinoma patients who underwent radical radiotherapy (P<0.05). Stratified analysis showed that, in the patients whose GTV volume≤50 cm(3), the median survival time of SIB and No-SIB group was 34.7 and 30.3 months (P=0.155), respectively. In the patients whose GTV volume>50 cm(3), the median survival time of SIB and No-SIB group was 16.1 and 20.1 months (P=0.218). The incidence of radiation esophagitis and radiation pneumonitis above Grade 3 in SIB group were 4.3% and 2.5%, significantly lower than 13.1% and 11% of No-SIB group (P<0.001). Conclusions: The survival benefit of SIB-RT in patients with locally advanced esophageal carcinoma is not inferior to non-SIB-RT, but without more adverse reactions, and shortens the treatment time. SIB-RT can be used as one option of the radical radiotherapy for locally advanced esophageal cancer.

[A multicenter retrospective study on the etiology of necrotizing pneumonia in children].

Objective: To investigate the etiology of necrotizing pneumonia (NP) in children and the clinical characteristics of NP caused by different pathogens in China. Methods: A retrospective, case-control study was performed in children with NP who were admitted to 13 hospitals in China from January 2008 to December 2019. The demographic and clinical information, laboratory data, etiological and radiological findings were analyzed. The data were divided into three groups based on the following years: 2008-2011, 2012-2015 and 2016-2019, and the distribution characteristics of the pathogens in different period were compared. Meanwhile, the pathogens of pediatric NP in the southern and northern China were compared. And the clinical characteristics of the Mycoplasma pneumoniae (MP) NP and the bacterial NP were also compared. T-test or Mann-Whitney nonparametric test was used for comparison of numerical variables, and χ2 test was used for categorical variables. Results: A total of 494 children with NP were enrolled, the median ages were 4.7 (0.1-15.3) years, including 272 boys and 222 girls. Among these patients, pathogens were identified in 347 cases and the pathogen was unclear in the remaining 147 cases. The main pathogens were MP (238 cases), Streptococcus pneumoniae (SP) (61 cases), Staphylococcus aureus (SA) (51 cases), Pseudomonas aeruginosa (13 cases), Haemophilus influenzae (10 cases), adenovirus (10 cases), and influenza virus A (7 cases), respectively. MP was the most common pathogen in all three periods and the proportion increased yearly. The proportion of MP in 2016-2019 was significantly higher than that in 2012-2015 (52.1% (197/378) vs. 36.8% (32/87), χ2=6.654, P=0.010), while there was no significant difference in the proportion of MP in 2012-2015 and that in 2008-2011 (36.8% (32/87) vs. 31.0% (9/29), χ²=0.314, P=0.575).Regarding the regional distribution, 342 cases were in the southern China and 152 in the northern China. Also, MP was the most common pathogen in both regions, but the proportion of MP was higher and the proportion of SP was lower in the north than those in the south (60.5% (92/152) vs. 42.7% (146/342), χ2=13.409, P<0.010; 7.9% (12/152) vs. 14.3% (49/342), χ2=4.023, P=0.045). Comparing the clinical characteristics of different pathogens, we found that fever and cough were the common symptoms in both single MP and single bacterial groups, but chest pain was more common (17.0% (34/200) vs. 6.1% (6/98), χ2=6.697, P=0.010) while shortness of breath and wheezing were less common in MP group (16.0% (32/200) vs. 60.2% (59/98), χ2=60.688, P<0.01; 4.5% (9/200) vs. 21.4% (21/98), χ2=20.819, P<0.01, respectively). The white blood cell count, C-reactive protein and procalcitonin in the bacterial group were significantly higher than those in the MP group (14.7 (1.0-67.1)×109/L vs. 10.5 (2.5-32.2)×109/L, 122.5 (0.5-277.3) mg/L vs. 51.4 (0.5-200.0) g/L, 2.13 (0.05-100.00) µg/L vs. 0.24 (0.01-18.85) µg/L, Z=-3.719, -5.901 and -7.765, all P<0.01). Conclusions: The prevalence of pediatric NP in China shows an increasing trend during the past years. MP, SP and SA are the main pathogens of NP, and the most common clinical symptoms are fever and cough. The WBC count, C-reactive protein and procalcitonin in bacterial NP are significantly higher than those caused by MP.

[Transcription factor EB related autophagy in the treatment of multiple myeloma and its mechanism].

Objective: To clarify the effects of bortezomib combined with or without siramesine on the proliferation of multiple myeloma cell lines, the expression changes of transcription factor EBC (TFEB) nuclear translocation and the level of autophagy, and to provide basis for further exploring the regulation mechanism of transcription factor TFEB on autophagy. Methods: The multiple myeloma cell lines RPMI8226 and U266 were cultured in vitro, and the multiple myeloma cells were treated with a certain concentration of bortezomib and siramesine. The changes of cell proliferation inhibition were detected by CCK-8 method. Real time PCR and Western blot were used to detect the relative expression of TFEB, autophagy-related factor LC3B, Beclin1, p62, LAMP1 mRNA and protein. Results: As the concentration of bortezomib increased and the duration of action increased, the proliferation inhibition rates of the two cell lines gradually increased (P<0.05) . The combination of the two drugs has a synergistic inhibitory effect on the proliferation of the above-mentioned multiple myeloma cell lines (P<0.05) . In the blank control group, single drug group, and combination drug group, the relative expression of TFEB mRNA and protein in the cytoplasm decreased sequentially (P<0.05) , and the relative expression of TFEB mRNA and protein in the nucleus increased sequentially (P<0.05) . The relative expression of autophagy-related factors LC3B, Beclin1, LAMP1 mRNA and protein increased sequentially, and the relative expression of p62 mRNA and protein decreased sequentially (P<0.05) . Conclusion: Bortezomib and siramesine can synergistically inhibit the growth of multiple myeloma cells, which is related to the increased autophagy expression in multiple myeloma cell lines and the expression of TFEB with nuclear translocation is also enhanced.

Correlation study between the magnetic resonance imaging features of breast cancer and expression of immune molecular subtypes.

OBJECTIVE: To investigate the correlation between breast cancer magnetic resonance imaging features and immune molecular subtypes. PATIENTS AND METHODS: A total of 129 breast cancer patients were selected as the research object. All the patients were diagnosed by histopathology. All of them had breast magnetic resonance imaging and examination data of immunohistochemical (IHC) ER, PR, HER-2, and Ki-67. The correlation of breast cancer magnetic resonance imaging features with different immune molecular subtypes was retrospectively analyzed. RESULTS: Breast cancer is divided into different molecular subtypes. There were 72 cases with Luminal A type (55.81%), 20 cases with Luminal B type (15.50%), 14 cases with HER-2+ type (HER-2 type for over-expression) (10.85%), 23 cases with TNBC type (ER, PR and HER-2 were negative) (17.84%). The magnetic resonance imaging features of breast cancer were included, the post-enhanced morphology, margins, internal enhancement features, time-signal intensity curve (TIC) and molecular subtype expression of lesions were significantly correlated with the immune molecular subtypes (C=0.602, 0.439, 0.350 and 0.407, p=0.000, 0.000, 0.006 and 0.000). Lesion morphology: Luminal A type was mainly oval, accounting for 76.39% (55/76). Luminal B type and HER-2+ type was mainly irregular, accounting for 75.00% (15/20) and 64.29% (9/14) respectively. TNBC type was mainly shown as lobulation, accounting for 60.87% (14/23). Margin of the lesion: Luminal A type was mainly smooth margin, accounting for 73.61% (53/72). Luminal B type and TNBC type were mainly irregular margin, accounting for 70.00% (14/20) and 56.52% (13/23) respectively. The margin of HER-2+ type was mainly spiculation, accounting for 64.29% (9/14). The internal enhancement features: Luminal A type was mainly even enhancement, accounting for 62.50% (45/72). Luminal B type and HER-2+ type were mainly heterogeneous enhancement, accounting for 65.00% (13/20) and 64.29% (9/14) respectively. TNBC type was mainly annular enhancement, accounting for 73.91% (17/23). TIC type: Luminal A type was mainly Type II, accounting for 66.67% (48/72). Luminal B, HER-2+ type and TNBC type was mainly Type III, accounting for 70.00% (14/20), 64.29% (9/14) and 60.87% (14/23) respectively. The clinical signs include painless breast lumps, bloody breast discharge, and orange peel-like skin changes, nipple retraction and nipple elevation. There is no significant correlation between the above signs and the expression of molecular subtypes (C=0.014, 0.129, 0.154, 0.097 and 0.057, p=0.999, 0.533, 0.447, 0.747 and 0.935 respectively), the difference is not statistically significant (p>0.05). CONCLUSIONS: The characteristics of breast cancer magnetic resonance imaging was certainly correlated with the expression of immune molecular subtypes. The breast cancer molecular subtypes can be predicted by the imaging signs, which can provide valuable information for preoperative neoadjuvant treatment of breast cancer.

[Clinical efficacy of two-staged Fowler-Stephens laparoscopic orchidopexy in the treatment of children with high cryptorchidism].

Objective: To Evaluate the clinic effect of two-staged laparoscopic Fowler-Stephens orchiopexy in the treatment of high cryptorchidism, and compare it with laparoscopic orchiopexy treatment without disconnecting spermatic vessels. Methods: A retrospective analysis was conducted on 20 cases of children with high cryptorchidism who were treated with two-staged Fowler-Stephens orchiopexy from January 2015 to April 2019 (F-S group). All the children in this group had unilateral cryptorchidism, age 6 to 18 months. The average age was 13.5 months. Seven cases were on the left side, and 13 cases were on the right side. There were 20 control children in the same age group who were treated with testicular fixation without disconnecting spermatic vessels, age 6 to 18 months. The average age was 12.5 months. Six cases were on the left side, and 14 cases were on the right side. Testicular ultrasonography and sex hormone examination were conducted before operation. F-S group met the indications for Fowler-Stephens surgical. In the first stage, the testicular vessels were doubly clipped at a site away from the testis in laparoscopic, and the second stage was scheduled about 6 months after the first stage. The children in the control group were treated with laparoscopic orchiopexy without disconnect spermatic vessels. The two groups were followed up to 6 months after the operation, and the testicular volume and sex hormone indexes of the two groups were measured. The testicular volume and sex hormones before and after the operation of the F-S group and the control group were respectively subjected to a self-control study, and a hormone comparison study was carried out between the two groups of children. Results: Both the F-S group and the control group successfully fixed the testes in the scrotum without tension during the operation. In both groups, 20 cases of testicular positions were reexamined 6 months after the operation without retraction. All the patients had a viable testis in scrotum after operation. Two of F-S group had an atrophic testis in the scrotum, and the others had a good vascularization detected on echo color doppler ultrasound. The average testicular volume of F-S group was (0.34±0.16) ml before operation and the postoperative one was (0.38±0.13) ml, P=0.089, P>0.05. In control group, the preoperative average testicular volume was (0.40±0.14) ml, and postoperative one was (0.40±0.15) ml, P=0.933, P>0.05. The testicular volume of two group had no significant difference. Sex hormone reexamination: Testosterone (T), estradiol (E2) and luteinizing hormone (LH) did not change after operation. Prolactin (PRL) in F-S group was 13.44 µg/L before operation and 12.3 µg/L after operation, PRL in control group was from 15.45 µg/L to 10.34 µg/L, P=0.732, the change of prolactin (PRL) has no significant difference. The median preoperative follicle stimulating hormone (FSH) in the F-S group was 1.18 U/L preoperatively and 1.61 U/L postoperatively; the median FSH of the control group was 1.21 U/L preoperatively and 1.1 U/L postoperatively. Compared between the two groups, the postoperative increase in the FS group was higher than that before the operation, P=0.032, P<0.05, the difference was statistically significant. The median of progesterone (PROG) in the F-S group was 0.25 nmol/L before operation and 0.17 nmol/L after operation; the median PROG of the control group was 0.56 nmol/L before operation and 0.24 nmol/L after operation. It was lower after the operation than before the operation, P=0.034, P<0.05, the difference was statistically significant. Conclusions: (1) Laparoscopic Fowler-stephens staging operation is an effective method for the treatment of patients with high cryptorchidism, and it is worthy of further promotion. (2) Disruption of spermatic cord vessels does have an impact on hormones changes. The choice of this surgical procedure should be carefully and fully evaluated.

[Increased Notch receptors induces CD8(+) T cell exhaustion in patients with prostate cancer].

Objective: To investigate Notch receptor expression in CD8(+) T cells in patients with prostate cancer, and to assess the influence of Notch signaling pathway on the function of CD8(+)T cells inpatients with prostate cancer. Methods: Forty-five patients with prostate cancer, forty-one patients with nonbacterial prostatitis, and thirty healthy controls who were hospitalized or followed-up in Shanxi Provincial People's Hospital between November 2017 and June 2018 were enrolled. CD8(+)T cells were purified, and mRNA relative levels of Notch1-4 were semi-quantified by reverse transcriptional real-time PCR. CD8(+)T cells were stimulated with Notch signaling inhibitor γ-secretase inhibitor (GSI). mRNA relative levels of perforin, granzyme B, and FasL were semi-quantified by reverse transcriptional real-time PCR. Percentages of PD-1 and CTLA-4 positive cells were investigated by flow cytometry. Direct contact and indirect contact coculture systems were set up between CD8(+)T cells and prostate cancer cell line LAPC4 cells. The influence of Notch signaling inhibition to CD8(+)T cell cytotoxicitywas assessed by measuringtarget cell death and cytokine secretion. One-Way ANOVA, LSD-t test, and paired t test was used for comparison. Results: mRNA relative levels of Notch1~4 were elevated in CD8(+)T cells from prostate cancer patients when compared with those from healthy controls and nonbacterial prostatitis patients (all P<0.05). There was CD8(+)T cell exhaustion in prostate cancer patients, which presented as decreased mRNA relative levels of perforin, granzyme B, and FasL (all P<0.000 1), as well as increased percentage of PD-1(+)CD8(+) (19.3%±5.4%) and CTLA-4(+)CD8(+)(11.7%±3.9%) cells. CD8(+)T cells from prostate cancer patients induced LAPC cell death was downregulated in direct contact coculture system (28.8%±6.4% vs 37.2%±2.6%, P=0.015). IFN-γsecretion was also reduced ((61.7±10.6)ng/L vs (88.6±20.2)ng/L, P=0.003 2). Inhibition of Notch signaling by GSI increased mRNA of perforin, granzyme B, and FasL in CD8(+)T cells from prostate cancer patients (all P<0.01), while reduced percentage of PD-1(+)CD8(+)(12.6%±2.5% vs 17.4%±4.7%, P=0.005 9) and CTLA-4(+)CD8(+) (12.0%±1.0% vs 14.1%±3.1%, P=0.011)cells. Notch signaling inhibition promoted LAPC4 cell death (34.3%±7.2%, P=0.000 2) which induced by prostate cancer derived CD8(+)T cells, and increased IFN-γ production ((88.4±33.6)ng/L, P=0.008 3). Conclusion: Elevated Notch receptors induced CD8(+)T cells exhaustion in prostate cancer patients.

[Efficacy analysis of the radiotherapy and chemotherapy in patients with stage â £ esophageal squamous carcinoma: a multicenter retrospective study of Jing-Jin-Ji Esophageal and Esophagogastric Cancer Radiotherapy Oncology Group (3JECROG R-01F)].

Objective: To evaluate the survival and prognostic factors of radiotherapy in patient with Ⅳ stage esophageal squamous carcinoma treated with radiation or chemoradiation. Methods: The medical records of 608 patients with stage Ⅳ esophageal squamous cell carcinoma who met the inclusion criteria in 10 medical centers in China from 2002 to 2016 were retrospectively analyzed. The overall survival and prognostic factors of all patients at 1, 3 and 5 years were analyzed. Results: The 1-, 3-, 5- year overall survival (OS) rates was 66.7%, 29.5% and 24.3% in stage ⅣA patients, and 58.8%, 29.0% and 23.5% in stage ⅣB patients. There was no statistical difference between the two groups (P=0.255). Univariate analysis demonstrated that the length of lesion, treatment plan, planned tumor target volume (PGTV) dose, subsequent chemotherapy, and degrees of anemia, radiation esophagitis, radiation pneumonia were related to the prognoses of patients with Ⅳ stage esophageal carcinomas after radiotherapy and chemotherapy (P<0.05). Multivariate analysis demonstrated that PGTV dose (OR=0.693, P=0.004), radiation esophagitis (OR=0.867, P=0.038), and radiation pneumonia (OR=1.181, P=0.004) were independent prognostic factors for OS. Conclusions: For patients with stage Ⅳ esophageal squamous cell carcinoma, chemoradiotherapy followed by sequential chemotherapy is recommended, which can extend the total survival and improve the prognosis of the patients. PGTV dose more than 60 Gy has better efficacy.

Methods: The clinical data of 196 patients with T1-2N0M0 ESCC who were treated with definitive radiotherapy in 10 hospitals were retrospectively analyzed. All sites were members of Jing-Jin-Ji Esophageal and Esophagogastric Cancer Radiotherapy Oncology Group (3JECROG). Radiochemotherapy were applied to 78 patients, while the other 118 patients received radiotherapy only. 96 patients were treated with three-dimensional conformal radiotherapy (3DCRT) and 100 treated with intensity-modulated radiotherapy (IMRT). The median dose of plan target volume(PTV) and gross target volume(GTV) were both 60 Gy. The median follow-up time was 59.2 months. Log rank test and Cox regression analysis were used for univariat and multivariate analysis, respectively. Results: The percentage of normal lung receiving at least 20 Gy (V(20)) was (18.65±7.20)%, with average dose of (10.81±42.05) Gy. The percentage of normal heart receiving at least 30 Gy (V(30)) was (14.21±12.28)%. The maximum dose of exposure in spinal cord was (39.65±8.13) Gy. The incidence of radiation pneumonia and radiation esophagitis were 14.80%(29/196) and 65.82%(129/196), respectively. The adverse events were mostly grade 1-2, without grade 4 toxicity. Median overall survival (OS) and progression-free survival (PFS) were 70.1 months and 62.3 months, respectively. The 1-, 3- and 5-year OS rates of all patients were 75.1%、57.4% and 53.2%, respectively. The 1-, 3- and 5-year PFS rates were 75.1%、57.4% and 53.2%, respectively. Multivariate analysis demonstrated that patients'age (HR=1.023, P=0.038) and tumor diameter (HR=1.243, P=0.028)were the independent prognostic factors for OS, while tumor volume were the independent prognostic factor for PFS. Conclusions: Definitive radiotherapy is a promising therapeutic method in patients with T1-2N0M0 ESCC. Patients' age, tumor diameter and tumor volume may impact patients' prognosis.

Effect of IL-1ß on apoptosis of synovial cells in rheumatoid arthritis rats via the NF-κB pathway.

OBJECTIVE: The aim of this study was to investigate the role of interleukin-1ß (IL-1ß) in the apoptosis of synovial cells in rheumatoid arthritis (RA) rats, and to explore the underlying mechanism. MATERIALS AND METHODS: The apoptosis of the synovial cells in RA rats in the IL-1ß group and the control group was analyzed by scoring under an electron microscope. The expressions of cleaved-poly (ADP-ribose) polymerase (PARP), PARP and anti-apoptosis gene products in synovial cells of IL-1ß treated RA rats were explored as well. Meanwhile, the expressions of B-cell lymphoma 2 (Bcl-2), Bcl-xL, and Active-Caspase3 in the synovial cells of RA rats with IL-1ß treatment were evaluated by the Western blotting. To further clarify the relationship between IL-1ß and the nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) pathway in the synovial cells of RA rats, the expressions of NF-κB regulated the gene products of matrix metalloproteinase-3 (MMP-3), MMP-9, cyclooxygenase-2 (Cox-2), and vascular endothelial growth factor (VEGF) in synovial cells of RA rats after that we investigated the treatment with IL-1ß (was investigated). In addition, the expression of NF-κB in the synovial cells of RA rats treated with IL-1ß was determined. RESULTS: The results showed that, compared with the control group, IL-1ß treatment significantly increased the number of apoptotic cells. This meant that IL-1ß treatment could promote the apoptosis of the synovial cells (p<0.05). IL-1ß treatment significantly promoted the expression level of cleaved-PARP (p<0.05). However, it remarkably reduced the expressions of Bcl-2 and Bcl-xL (p<0.05). Meanwhile, the level of the active-Caspase3 in the synovial cells of RA rats treated with IL-1ß was significantly enhanced (p<0.01). In comparison with the control group, the IL-1ß group exhibited significantly elevated expressions of NF-κB-regulated gene products in the synovial cells of RA rats (p<0.01). Besides, the positive markers of the activated NF-κB were detected in the synovial cells of RA rats in the IL-1ß group and the control group. The results demonstrated that they were mainly located in the nucleus of the IL-1ß group. CONCLUSIONS: IL-1ß can promote the apoptosis of the synovial cells in RA rats via the NF-κB pathway.

[Status of non-steroidal anti-inflammatory drugs use in areas with a high incidence of upper gastrointestinal cancer in China: a multi-center cross-sectional survey].

Objective: To describe the status of non-steroidal anti-inflammatory drugs (NSAIDs) use in areas with a high incidence of upper gastrointestinal cancer in China. Methods: This study was based on the National Key Research and Development Program of "National Precision Medicine Cohort of Esophageal Cancer" and "Study on Identification and Prevention of High-risk Populations of Gastrointestinal Malignancies (Esophageal cancer, Gastric cancer and Colorectal cancer)" . From January 2017 to August 2018, 212 villages or communities with a high incidence of esophageal cancer or gastric cancer were selected from 12 regions in 6 provinces. A total of 35 910 residents aged between 40 and 69 years old who met the inclusion criteria and signed the informed consent were investigated and enrolled in this study. The use of NSAIDs, demographic characteristics, health-related habits, height, weight, and blood pressure were collected by the questionnaire and physical examination. The status of main NSAIDs (aspirin, acetaminophen and ibuprofen) use with the difference varying in genders, age groups and regions were analyzed by using χ(2) test and Cochran-Armitage trend analysis method. Results: Of 35 910 subjects, the mean age was (54.6±7.1) years old and males accounted for 43.42% (15 591). The overall prevalence of NSAIDs intake was 4.56% (1 638), but it significantly varied in different provinces (P<0.001). The overall prevalence of NSAIDs intake was 4.87% (1 750) in females, which was significantly higher than that in males 4.24% (1 524) (P<0.001). The prevalence of NSAIDs intake increased with age (P for trend <0.001). As the frequency of NSAIDs intake increased, the incidence of gastrointestinal symptoms, gastrointestinal ulcers and black stools increased (P for trend <0.05 for all). Conclusion: The use of NSAIDs is prevalent in some areas with a high incidence of upper gastrointestinal cancer in China. The increased use of NSAIDs may lead to more adverse effects related to the gastrointestinal tract.

SNHG16 promotes the progression of osteoarthritis through activating microRNA-93-5p/CCND1 axis.

OBJECTIVE: This study aims to investigate whether SNHG16 (small nucleolar RNA host gene 16) can promote the progression of osteoarthritis (OA) by regulating the microRNA-93-5p/Cyclin D1 (CCND1) axis, thereby finding new therapeutic targets for the treatment of OA. PATIENTS AND METHODS: A total of 23 OA patients and 23 patients undergoing lower extremity amputation were enrolled in this study. We collected their cartilage tissues from knee joint for isolating chondrocytes. The relative levels of SNHG16, CCND1 and microRNA-93-5p in cartilage tissues of OA patients and controls were determined by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). The regulatory effect of SNHG16 on proliferative potential of chondrocytes was evaluated by Cell Counting Kit-8 (CCK-8) and colony formation assay, respectively. Cell cycle progression was examined using flow cytometry. Dual-Luciferase reporter gene assay was conducted to verify the binding between SNHG16 with microRNA-93-5p and microRNA-93-5p with CCND1. Rescue experiments were performed to elucidate whether SNHG16 regulated CCND1 expression by targeting microRNA-93-5p. RESULTS: The expressions of SNHG16 and CCND1 upregulated, while microRNA-93-5p downregulated in cartilage tissues of OA patients relative to controls. Correlation regression analyses showed a negative expression correlation between SNHG16 and microRNA-93-5p, as well as CCND1 and microRNA-93-5p in OA patients. On the contrary, SNHG16 expression was positively correlated to CCND1 expression in OA. The knockdown of SNHG16 suppressed viability, cloning ability and cell cycle progression, but induced apoptosis in chondrocytes. Dual-Luciferase reporter gene assay showed that SNHG16 could bind to microRNA-93-5p. SNHG16 knockdown markedly upregulated the expression of microRNA-93-5p. Moreover, the knockdown of microRNA-93-5p reversed the inhibited viability due to SNHG16 knockdown. Transfection of microRNA-93-5p mimics markedly inhibited CCND1 expression. Importantly, CCND1 overexpression reversed the inhibitory effect of SNHG16 knockdown on chondrocyte viability. CONCLUSIONS: SNHG16 promotes the development of OA by regulating microRNA-93-5p/CCND1 axis.

[Comprehensive analysis of unplanned abdominal - pelvic reoperations in Peking University Cancer Hospital and Institute from 2008 to 2018].

Objective: To summarize the characteristics of abdominal-pelvic unplanned reoperation (URO) in a cancer hospital. Methods: Retrospectively descriptive cohort research was adopted. The classification of diseases was based on ICD-10, and surgical classification was based on ICD-9-CM-3. Medical record summary database from 2008 to 2018 in Beijing Cancer Hospital was collected, and all URO information of abdominal-pelvic surgery was retrieve. The time of URO, disease type, surgery type and cause were statistically analyzed. Distribution of main disease incidence and constituent ratio, and the application of major surgery and surgery type composition ratio were analyzed as well. Results: From 2008 to 2018, a total of 46854 cases underwent abdominal-pelvic surgery (including gastrointestinal, hepatic-biliary-pancreatic, gynecological, urological, or esophageal cancer surgery) and 713 patients received URO (1.52%), including 486 males and 227 females (2.14:1.00) with a mean age of (58.1±12.2) years. A total of 246 patients (34.50%) had comorbidity, and with comorbidity: without comorbidity was 1.13:1.00. The hospital stay was (44.5±43.0) days, and the total cost was (178000±112000) yuan. There were 22 deaths (3.09%). The median interval between URO and the first operation was 8 (0 to 131) days. The highest rate of URO was 2.45% (89/3629) in 2012, while the lowest was 0.95% (53/5596) in 2015. The top 3 major cancer types of URO included colorectal cancer (222 cases, 31.14%), gastric cancer (166 cases, 23.28%) and esophageal cancer (45 cases, 6.31%). The cancer types with the highest URO rate included pancreatic cancer (3.97%, 30/756), gastric cancer (1.81%, 166/9171) and colorectal cancer (1.80%, 222/12333). The top 3 surgical procedures resulting in URO were rectal resection (109 cases, 15.29%), total gastrectomy (79 cases, 11.08%), and total pancreatectomy (64 cases, 8.98%). Focusing on 497 URO cases from 2012 to 2018, 465 cases (93.56%) followed relatively difficult grade III and IV surgery, while only 32 cases (6.44%) followed grade I and II surgery. The top 5 main causes of URO were bleeding (225 cases, 31.56%), anastomotic leak (225 cases, 31.56%), infection (89 cases, 12.48%), intestinal obstruction (53 cases, 7.43%), and wound dehiscence (35 cases, 4.91%), adding up to a total of 87.94% of all URO. Conclusion: This study summarizes the epidemiology of abdominal - pelvic URO in our cancer institution, providing the solid baseline for future investigation of URO and the subsequent formulation of corresponding prevention and intervention measures.

MicroRNA-29 targets FGF2 and inhibits the proliferation, migration and invasion of nasopharyngeal carcinoma cells via PI3K/AKT signaling pathway.

OBJECTIVE: Studies have indicated that miRNAs may prove essential therapeutic targets for the treatment of cancer. The study was designed to investigate the role and therapeutic potential of miR-29 in nasopharyngeal cancer. MATERIALS AND METHODS: The quantitative Real-time polymerase chain reaction (qRT-PCR) was used for expression analysis. WST-1 assay was used for cell viability assessment. The 4',6-diamidino-2-phenylindole (DAPI) staining and electron microscopic analysis was used for the detection of apoptosis and autophagy, respectively. Transwell assays were used for cell migration and invasion assay. RESULTS: It was found that miR-29 is significantly downregulated in nasopharyngeal cancer cell lines. Overexpression of miR-29 causes decrease in the viability of CNE2 nasopharyngeal cancer cells via induction of apoptosis and autophagy. Bioinformatics analysis indicated FGF2 to be the target of miR-29 in CNE2 cells, which was also confirmed by luciferase reporter assay. The qRT-PCR results showed fibroblast growth factor 2 (FGF2) to be significantly upregulated in the nasopharyngeal cancer cell lines. However, miR-29 overexpression in CNE2 cells resulted in post-transcriptional suppression of FGF2 expression. Nonetheless, silencing of FGF2 also caused inhibition of CNE2 cell proliferation via induction of apoptosis and autophagy. Overexpression of FGF2 could reverse the effects of miR-29 overexpression on the proliferation of CNE2 cells. Moreover, overexpression of miR-29 causes significant decline in the phosphorylation of PI3K and AKT expression cells and inhibits their migration and invasion of the CNE2 cells. Finally, miR-29 overexpression could also suppress the subcutaneous xenografted tumor growth. CONCLUSIONS: The findings of the present study indicate the therapeutic implications of miR-29 in nasopharyngeal carcinoma.
