ABSTRACT

The main components of the gastric tumor stroma consist of cells in both the immune and non-immune microenvironments. The effectiveness of a series of therapeutic measures such as adjuvant chemotherapy is closely related to the composition of gastric tumor stroma. By analyzing the components in the gastric tumor stroma, we understand the characteristics of the constituents in the pathological structure of gastric cancer, and further explore the connection of each component of the stroma with pathological structure and regulatory mechanisms of stroma components on the occurrence and progression of gastric tumors. Combined with artificial intel-ligence technology to analyze the pathological features related to stroma components of tumor microenvironment, the dynamic changes of immune microenvironment and non-immune microen-vironment in gastric cancer are expected to reveal.

ABSTRACT

OBJECTIVE@#To investigate the short-term clinical effect of the computer virtual technique combined with pelvic reduction frame in the treatment of complex pelvic fractures.@*METHODS@#Thirty patients with Tile C pelvic fractures treated by percutaneous minimally invasive pelvic reduction frame from April 2018 to April 2020 were retrospectively analyzed, including 21 males and 9 females, aged from 19 to 57 (39.40±9.85) years old. The patient's pelvic CT DICOM data were imported into Mimics software to reconstruct the virtual fracture model. Virtual reduction and nail placement were carried out on the fracture model, and then simulated fluoroscopy was carried out to record the ideal fluoroscopy orientation and angle to guide the correct fluoroscopy during operation. The operation time, fluoroscopy times and intraoperative blood loss were recorded. The quality of fracture reduction was evaluated by Matta image score standard, and the postoperative function was evaluated by Majeed function score standard.@*RESULTS@#All 30 patients achieved closed reduction and percutaneous screw fixation. According to Matta score, the excellent and good rate of fracture reduction was 93.3%(28/30). A total of 67 channel screws were inserted, and the excellent and good rate was 98.5%(66/67). The operation time was (173.54±79.31) min, fluoroscopy time was (90.81±41.11) times, intraoperative blood loss was (81.21±43.97) ml. All incisions healed at one stage without broken nails or re-displacement of fractures. All patients were followed up for 12 months. At the final follow-up, Majeed function score was 73 to 94(85.66±5.33) scores.@*CONCLUSION@#Computer virtual technology combined with pelvic reduction frame could rapidly, accurately and safely reduce and fix unstable pelvic fractures. Computer virtualization could help surgeons to recognition and understanding pelvic fractures, pelvic reduction frame could improve the surgeon's ability to manage complex and unstable pelvic injuries.

ABSTRACT

Objective:To investigate the effects of Flexi-bar on nonspecific low back pain. Methods:From June, 2020 to January, 2021, 30 patients with nonspecific low back pain were enrolled. Firstly, all the patients performed core stabilization exercise (supine bridge, curl-up and four-point support) using Flexi-bar or not, respectively. And the difference of electromyography (EMG) root mean square (RMS) value of transversus abdominis and multifidus was observed. Secondly, they were randomly divided into control group (n = 15) and experimental group (n = 15). The control group performed core stabilization exercise, and the experimental group received Flexi-bar training in addition, 30 minutes a time, three times a week, for six weeks. They were evaluated with Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI), and measured the thickness of transversus abdominis and the area of multifidus before and after training. Results:Firstly, there was significant difference in RMS of transversus abdominis and multifidus between using Flexi-bar or not (|t| > 2.468, P < 0.05), except the RMS of transversus in supine bridge (|t| < 2.029, P > 0.05). Secondly, before training, there was no significant difference between the control group and the experimental group (|t| < 1.944, P > 0.05); after training, the scores of VAS and ODI significantly decreased (|t| > 6.808, P < 0.001), the thickness of transversus abdominis and the area of multifidus significantly increased (|t| > 5.937, P < 0.001), and all the indexes were better in the experimental group than in the control group (|t| > 2.411, P < 0.05), except the thickness of transverse abdominis (t = -1.431, P > 0.05). Conclusion:Flexi-bar could facilitate to reduce pain and improve the function of patients with nonspecific low back pain.

ABSTRACT

BACKGROUND@#Investigations of the pathogenic mechanisms in motor neurons (MNs) derived from amyotrophic lateral sclerosis (ALS) disease-specific induced pluripotent stem (iPS) cell lines could improve understanding of the issues affecting MNs. Therefore, in this study we explored mutant superoxide dismutase 1 (SOD1) protein expression in MNs derived from the iPS cell lines of ALS patients carrying different SOD1 mutations.@*METHODS@#We generated induced pluripotent stem cell (iPSC) lines from two familial ALS (FALS) patients with SOD1-V14M and SOD1-C111Y mutations, and then differentiated them into MNs. We investigated levels of the SOD1 protein in iPSCs and MNs, the intracellular Ca2+ levels in MNs, and the lactate dehydrogenase (LDH) activity in the process of differentiation into the MNs derived from the controls and ALS patients' iPSCs.@*RESULTS@#The iPSCs from the two FALS patients were capable of differentiation into MNs carrying different SOD1 mutations and differentially expressed MN markers. We detected high SOD1 protein expression and high intracellular calcium levels in both the MN and iPSCs that were derived from the two SOD1 mutant patients. However, at no time did we observe stronger LDH activity in the patient lines compared with the control lines.@*CONCLUSIONS@#MNs derived from patient-specific iPSC lines can recapitulate key aspects of ALS pathogenesis, providing a cell-based disease model to further elucidate disease pathogenesis and explore gene repair coupled with cell-replacement therapy. Incremental mutant expressions of SOD1 in MNs may have disrupted MN function, either causing or contributing to the intracellular calcium disturbances, which could lead to the occurrence and development of the disease.

ABSTRACT

BACKGROUND@#Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder associated with loss of motor neurons. Our objective was to explore the epidemiology, clinical features, and survival factors of 1809 patients with ALS.@*METHODS@#We analyzed 1809 ALS patients, who were recruited from the Peking University Third Hospital from January 2005 to December 2015. Demographic data and disease-related parameters were collected. Kaplan-Meier curves were used to compare survival time. Cox proportional hazards function and the hazard ratio were used to identify adjusted prognostic predictors.@*RESULTS@#The results showed that the average annual incidence in Beijing alone was 0.38 cases/100,000 person-years and the mean age of onset was 48.88 ± 11.35 (95% confidence interval [CI]: 48.17-49.85) years. The median survival time from onset to death/tracheostomy was 58.89 ± 33.03 (95% CI: 51.46-63.84) months. In the adjusted Cox proportional hazard model, age of onset, diagnosis delay, rate of disease progression (Amyotrophic Lateral Sclerosis Functional Rating Scale Revised decline [points/month]), and body mass index all had an independent effect on survival in ALS.@*CONCLUSIONS@#Our study provides information on epidemiology, clinical features, and survival factors of patients with ALS in China. These results can be helpful in clinical practice, clinical trial design, and validation of new tools to predict disease progression.

ABSTRACT

Objective:To evaluate the effect of medical compression elastic stockings or intermittent pneumatic pressure pumps on intraoperative hemodynamics in patients in the lithotomy position under general anesthesia.Methods:A total of 100 patients, aged 30-59 yr, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, scheduled for elective colorectal surgery or gynecological surgery in the lithotomy position under general anesthesia, with expected operation time>60 min, were divided into 2 groups ( n=50 each) using a random number table method: pressure pump group (group PP) and elastic stocking group (group ES). After entering the operating room (T 0), immediately after anesthesia induction (T 1), at 5 and 30 min of the lithotomy position (T 2, 3) and at the end of surgery (T 4), systolic and diastolic blood pressure (SBP, DBP) and heart rate (HR) were measured, and the requirement for vasoactive agents was recorded. Results:Compared with the values at T 0, SBP was significantly decreased at T 1-3 in group PP and at T 1 in group ES ( P<0.05). Compared with group PP, SBP was significantly increased at T 2, 3 in group ES ( P<0.05), no significant change was found DBP and HR at each time point ( P>0.05), and the intraoperative consumption of ephedrine was reduced ([16±9]mg vs.[8±5]mg, P<0.05). Conclusion:Medical compression elastic stockings produces less interference in intraoperative hemodynamics in patients in the lithotomy position under general anesthesia, and its safety is better than intermittent pneumatic pressure pumps.

ABSTRACT

OBJECTIVE@#Bufalin is an effective drug for the treatment of liver cancer. But its high toxicity, poor water-solubility, fast metabolism and short elimination half-life limit its use in tumor treatment. How to make the drug accumulate in the tumor and reduce side effects while maintaining its efficacy are urgent problems to be solved. The goal of this study is to solve these problems.@*METHODS@#A copolymer with tunable poly-N-isopropylacrylamide and polylactic acid was designed and synthesized. The corresponding dual targeting immunomicelles (DTIs) loaded with bufalin (DTIs-BF) were synthesized by copolymer self-assembly in an aqueous solution. The size and structure of DTIs-BF were determined by ZetaSizer Nano-ZS and transmission electron microscopy. Then, its temperature sensitivity, serum stability, critical micelle concentration (CMC), entrapment efficiency (EE), drug release and non-cytotoxicity of blank block copolymer micelles (BCMs) were evaluated. Next, the effects of DTIs-BF on cellular uptake, cytotoxicity, and tumor cell inhibition were evaluated. Finally, the accumulation of DTIs-fluorescein isothiocyanate (FITC) and the in vivo anti-tumor effect were observed using an interactive video information system.@*RESULTS@#DTIs-BF had a small size, spherical shape, good temperature sensitivity, high serum stability, low CMC, high EE, and slow drug release. The blank BCMs had very low cytotoxicity. Compared with free bufalin, the in vitro cellular internalization and cytotoxicity of DTIs-BF against SMMC-7721 cells were significantly enhanced, and the effects were obviously better at 40 °C than 37 °C. In addition, the therapeutic effect on SMMC-7721 cells was further enhanced by the programmed cell death specifically caused by bufalin. When DTIs-FITC were injected intravenously in BALB/c nude mice bearing liver cancer, the accumulation of FITC was significantly increased in tumors.@*CONCLUSION@#DTIs-BF is a potentially effective nano-formulation and has broad prospects in the clinical treatment of liver cancer.

ABSTRACT

We aim to design a new glanuloplasty procedure combined with spongiosum to reduce the incidence of glans dehiscence and coronal fistula after proximal hypospadias repair. Patients who underwent urethroplasty by dorsal preputial island flap for proximal hypospadias between January 2014 and December 2016 were reviewed in this retrospective cohort study. Those who underwent spongiosum-combined glanuloplasty comprised the new-maneuver group, whereas those who underwent conventional glanuloplasty comprised the control group. The incidence of complications was then compared. In the new-maneuver group, dysplastic corpus spongiosum alongside lateral Buck's fascia (0.3-0.4 cm wide) on both sides of the urethral plate was separated from the proximal normal spongy tissue, joining into the glans wings to increase tissue volume and covering the neourethra in the glans penis. In the control group, the neourethra was covered with superficial fascia under the coronal sulcus. As a result, the new-maneuver and control groups comprised 47 and 28 patients, respectively. In the new-maneuver group, no glans dehiscence was detected; however, two (4.3%) patients had coronal fistula, two (4.3%) had urethral stricture, and four (8.5%) had diverticulum. In the control group, two (7.1%) patients had glans dehiscence, eight (28.6%) had coronal fistula, four (14.3%) had urethral stricture, one (3.6%) had diverticulum, and one (3.6%) had penile curvature recurrence. The new-maneuver group had less incidences of coronal fistula (P < 0.001), glans dehiscence (P = 0.033), and urethral stricture (P = 0.008) but had a higher incidence of diverticulum than the control group (P = 0.040). It clearly demonstrates that spongiosum-combined glanuloplasty can significantly reduce the incidences of coronal fistula and glans dehisce.

ABSTRACT

Objective:To analyze the role of preoperative circulating tumor cell(CTC) and circulating tumor vascular endothelial cells (CTEC) in the diagnosis of gastric cancer and its correlation with the clinicopathological characteristics of gastric cancer.Methods:Sixty-two gastric cancer patients and 11 patients of benign gastric diseases were enrolled. Subtraction enrichment (SE) and immunofluorescence staining-chromosome fluorescence in situ hybridization (i·FISH) were used to integrate the unique SE-i ·FISH technology platform detecting patients′ CTC and CTEC.Results:The number of CTC in the gastric cancer group was significantly higher than that in the control group ( t=2.693, P=0.009); the number of CTEC in the gastric cancer group was higher than the control group ( t=2.015, P=0.048). With the cut-off value being set at 9 cells/6 ml in blood, the sensitivity of CTC in the diagnosis of gastric cancer is 84%, and the specificity is 82% (AUC=0.876, 95% CI, 0.792-0.963, P<0.01); When set at 6 cells/6 ml, the sensitivity of CTEC in the diagnosis of gastric cancer is 50%, and the specificity is 100%(AUC=0.727, 95% CI, 0.603-0.851, P=0.02). CTC positive is closely related to tumor location(χ 2=4.292, P=0.038 ) and TNM stage(CTC≥10, χ 2=4.848, P=0.028; CTC≥11, χ 2=6.234, P=0.013). CTEC positive is closely related to serum CA19-9(χ 2=4.858, P=0.028) and serum CA724 (χ 2=4.108, P=0.043 ) . Conclusion:SE-i·FISH technology has high sensitivity and specificity in the detection of CTC and CTEC of gastric cancer.

ABSTRACT

Objective:To develop health-related physical fitness measurement scale and assess its reliability and validity among older adults.Methods:The health-related physical fitness measurement scale was developed through Delphi method and field investigation method.And the authority coefficient, Kendall's coefficient and variation coefficient were analyzed.A multi-stage random sampling technique was adopted to select 410 older adults to investigate the reliability and validity of health-related physical fitness measurement scale with test-retest reliability, Cronbach's α coefficient and Guttman Split-Half coefficient and structural validity by IBM SPSS 20.0 and AMOS 22.0.Results:The health-related physical fitness measurement scale consisted of 3 dimensions (organic function, motor function, physical adaptive capacity) and 15 indexes.The Cronbach's α coefficient was 0.84.The Spearman-Brown correlation coefficient and Guttman Split-Half coefficient were both 0.82.The test-retest reliability between the first measurement and retest after 1 week was 0.84.Three factors were extracted by exploratory factor analysis, which were basically consistent with the theoretical concept of the scale, but the items of the theoretical conception were different from the actual ones.Confirmatory factor analysis based on the theoretical conception showed that all the indexes met the requirements of reference value as well(χ 2/ df=2.38, GFI=0.94, AGFI=0.91, CFI=0.92, TLI=0.91, TFI=0.92, RMSEA=0.06). Conclusion:The health-related physical fitness measurement scale has good reliability and validity in measuring the health fitness level of the elderly population in Guangzhou.

ABSTRACT

BACKGROUND@#Andersson lesions (ALs) are not uncommon in ankylosing spondylitis (AS). Plain radiography (PR) is widely used for the diagnosis of ALs. However, in our practice, there were some ALs in AS patients that could not be detected on plain radiographs. This study aimed to propose the concept of occult ALs and evaluate the prevalence and radiographic characteristics of the occult ALs in AS patients.@*METHODS@#A total of 496 consecutive AS patients were admitted in the Affiliated Drum Tower Hospital, Medical School of Nanjing University between April 2003 and November 2019 and they were retrospectively reviewed. The AS patients with ALs who met the following criteria were included for the investigation of occult ALs: (1) with pre-operative plain radiographs of the whole-spine and (2) availability of pre-operative computed tomography (CT) and/or magnetic resonance imaging (MRI) of the whole-spine. The occult ALs were defined as the ALs which were undetectable on plain radiographs but could be detected by CT and/or MRI. The extensive ALs involved the whole discovertebral junction or manifested as destructive lesions throughout the vertebral body. Independent-samples t test was used to compare the age between the patients with only occult ALs and those with only detectable ALs. Chi-square or Fisher exact test was applied to compare the types, distribution, and radiographic characteristics between detectable and occult ALs as appropriate.@*RESULTS@#Ninety-two AS patients with a mean age of 44.4 ± 10.1 years were included for the investigation of occult ALs. Twenty-three patients had occult ALs and the incidence was 25% (23/92). Fifteen extensive ALs were occult, and the proportion of extensive ALs was significantly higher in detectable ALs (97% vs. 44%, χ2 = 43.66, P < 0.001). As assessed by PR, the proportions of osteolytic destruction with reactive sclerosis (0 vs. 100%, χ2 = 111.00, P < 0.001), angular kyphosis of the affected discovertebral units or vertebral body (0 vs. 22%, χ2 = 8.86, P = 0.003), formation of an osseous bridge at the intervertebral space adjacent to ALs caused by the ossification of the anterior longitudinal ligament (38% vs. 86%, χ2 = 25.91, P < 0.001), and an abnormal height of the affected intervertebral space were all significantly lower in occult ALs (9% vs. 84%, χ2 = 60.41, P < 0.001).@*CONCLUSIONS@#Occult ALs presented with more subtle radiographic changes. Occult ALs should not be neglected, especially in the case of extensive occult ALs, because the stability of the spine might be severely impaired by these lesions.

ABSTRACT

Objective:To study the relationship between compartmental kneeosteoarthritis (KOA) and osteoporosis (OP).Methods:A total of 118 KOA patients with 50~80 years old and 16.5~38 of body mass index (BMI) were selected as the KOA group, in which the patient with OP caused by secondary factors were excluded. 42 patients who did not suffer from KOA who matched the age of patients in the KOA group were selected. The age, BMI, bone mineral density (BMD) and other data of the two groups of patients were collected. The correlation analysis between KOA and OP was conducted to determine the degree of correlation, so as to reveal the relationship between the incidence, progression, prognosis of KOA and OP.Results:BMD was correlated with BMI. BMD was negatively correlated with age. The incidence of KOA and OP was correlated with age. There is a large correlation between KOA and OP, and the probability of KOA associated with OP is high. For KOA patients, OP is less likely to be accompanied by a higher BMI, while OP is more likely to be accompanied by a lower BMI.Conclusions:OP is one of the pathogenic factors of KOA. KOA patients should be treated with anti-OP before and after surgery.

ABSTRACT

Objective:To compare the antibacterial activity of domestic and branded tigecycline with in vitro pharmacokinetics (PK)/pharmacodynamics (PD) model. Methods:The in vitro PK automatic simulation system PASS400 was used to simulate different doses of tigecycline administration regimen (100 mg, 1 time/d; 50 mg, 12 h/d; 100 mg, 12 h/d), and to observe domestic and imported tigecycline time sterilization curve and related pharmacodynamic parameters of the drug against the standard strain of Escherichia coli (ATCC25922), carbapenem-resistant Klebsiella pneumoniae (ATCC BAA-1706) and the clinical strain of Acinetobacter baumannii (AB-16703). The GraphPad Prism 7 statistical software was used to analyze the data. Results:Under the condition of simulating different doses of PK, domestic and original tigecycline had similar antibacterial effects, but both showed weak antibacterial effects. The time sterilization curves of the two were almost overlapped, and the maximum sterilization amount was less than 2 log. Within 24 h, the bacteria all recovered to the growth plateau. In the comparison of PD parameters, the original and domestic tigecycline (100 mg, 1 time/12 h) had the maximum bactericidal doses of (-1.101±0.147) lg CFU/mL and (-1.105±0.208) lg CFU/mL for Escherichia coli ATCC25922; the maximum bactericidal capacity for Klebsiella pneumoniae ATCC BAA-1706 was (-1.999±0.187) lg CFU/mL and (-1.865±0.066) lg CFU/mL; the maximum bactericidal capacity for Acinetobacter baumannii AB-16703 was (-0.240±0.209) lg CFU/mL and (-0.230±0.187) lg CFU/mL. Under different dosage regimens, the maximum sterilization amount against the three bacteria, the time required for the bacteria to regenerate to the initial amount, the 24 h bacterial reduction, and the difference between the area of the sterilization and recovery growth curve and the blank control curve were all not statistical significant between the two drugs ( P>0.05). Conclusion:Tigecycline cannot show good antibacterial activity under the conditions of simulating human drug metabolism in vitro. The original branded tigecycline and domestic tigecycline have similar in vitro PK/PD effects.

ABSTRACT

Objective:To investigate the clinical effect of thoracoscopy combined with puncture-positioned internal fixation of multiple rib fractures accompanied with hemopneumothorax.Methods:A retrospective case-control study was used to analyze the clinical data of 68 patients with multiple rib fractures accompanied with hemopneumothorax admitted to Fujian Provincial Hospital from September 2016 to December 2018, including 49 males and 19 females, aged 25-86 years [(47.3±7.4)years]. There were 55 patients with unilateral lung contusion and laceration, and rest 13 patients with bilateral lung contusion and laceration. A total of 36 patients were treated by thoracoscopy combined with puncture-positioned internal fixation (thoracoscopy group) and 32 patients by open reduction group (open reduction group). The incision length, operation time, intraoperative blood loss, chest tube drainage time, ICU hospitalization time, total hospitalization time, and complications were recorded. Numeric rating scale (NRS) score was assessed at postoperative 1, 2, 3, 7 days. The MOS 36-item short-form health survey (SF-36) was conducted at the latest follow-up.Results:All patients were followed up for 8-34 months [(18.9±4.3)months]. Thoracoscopy group showed incision length of (4.3±1.3)cm, operation time of (66.3±12.1)minutes, intraoperative blood loss of (86.5±23.4)ml, chest tube drainage time of (5.3±1.1) days, ICU hospital stay of (2.3±0.8)days, total hospital stay of (6.8±1.7)days, and total complication rate of 8%, showing significant differences compared to open reduction group [(11.6±2.2)cm, (105.9±19.4)minutes, (191.4±35.6)ml, (8.1±1.6)days, (4.7± 1.4)days, (10.6±2.1)days, 29%] ( P<0.05 or 0.01). In thoracoscopy group, the NRS scores at day 1, 2, 3, and 7 were respective (6.6±1.2)points, (5.9±1.0)points, (4.4±0.9)points and (2.7±0.7)points, significantly lower than those in open reduction group [(7.3±1.2)points, (7.0±1.1)points, (5.7±1.0)points and (3.9±0.8)points] ( P<0.05 or 0.01). The SF-36 score in thoracoscopy group was (86.4±12.1)points, significantly higher than that in open reduction group [(75.6±11.5)points] ( P<0.01). Conclusions:Compared with open reduction and internal fixation, thoracoscopy combined with puncture-positioned internal fixation for multiple rib fractures has the advantages of smaller surgical incision, shorter operation time, less intraoperative bleeding, shorter chest tube drainage time, shorter ICU hospital stay, shorter total hospital stay, and less postoperative complications. The technique can also reduce the postoperative pain and improve the patients' quality of life.

ABSTRACT

Objective:To observe the effects of Kinesio Taping and kneepad on position sense of knee in healthy young adult male. Methods:In September, 2019, 20 healthy adult male aged 21 to 27 were selected. They were measured the joint angle error in angle reproduction test, and tested with functional reach test (FRT), 10-meter walking time (10MWT), and Timed "Up and Go" Test (TUGT) under follow four conditions: non-intervention, simple Kinesio Taping, simple kneepad, and both Kinesio Taping and kneepad. Results:For the angle error, it was the most under non-intervention, and the least under simple Kinesio Taping (F = 61.260, P < 0.001). For FRT, there was no significant difference among all the conditions (F = 1.793, P = 0.988). For 10MWT, it was the least under simple Kinesio Taping (F = 23.817, P < 0.001). For TUGT, it was the most under non-intervention (F = 19.865, P < 0.001). Conclusion:Kinesio Taping can improve position sense of knee, as well as walking, without further benefit along with kneepad.
