ABSTRACT
Objective:To investigate the effect of enhanced recovery after surgery (ERAS) on the surgical treatment of radiation enteritis with intestinal obstruction.Methods:A total of 80 patients with radiation enteritis and intestinal obstruction admitted to the Department of General Surgery, the Eighth Center of Chinese PLA General Hospital from June 2015 to December 2019 were selected and divided into observation group and control group according to the principle of baseline feature matching, with 40 cases in each group.Fourty cases in the control group received conventional surgical treatment combined with conventional rehabilitation intervention, while 40 cases in the observation group received conventional surgical treatment combined with ERAS intervention.According to hemoglobin (HGB), albumin (ALB), prealbumin (PA), transferrin (TRF), the nutritional status of patients in the two groups was compared before and after intervention.According to interleukin-2 (IL-2), interleukin-6 (IL-6), interleukin-8 (IL-8), hypersensitivity C-reactive protein (hs- CRP), tumor necrosis factor-α (TNF-α), the changes of inflammatory factors in the two groups was compared before and after intervention.The immunoglobulin (Ig) A, G and M of the two groups was compared before and after intervention.The postoperative recovery and the incidence of postoperative complications was observed in the two groups.Results:After the intervention, the level of HGB(125.56±11.18) g/L, ALB(42.46±3.95) g/L, PA(0.28±0.03) g/L and TRF(2.60±0.30) g/L in the observation group was higher than that in the control group (102.95±11.12), (36.28±4.25), (0.20±0.05), (2.09±0.27) g/L, respectively, and the differences between the two groups were significant (all P<0.001). After the intervention, the level of IL-2(3.69±0.79) ng/L, IL-6(15.79±7.17) ng/L, IL-8(6.24±1.25) ng/L, hs-CRP(12.51±2.34) ng/L, TNF-α(1.51±0.68) μg/L in the observation group was lower than that in the control group(7.26±1.23) ng/L, (23.82±6.95) ng/L, (9.13±1.71) ng/L, (17.63±2.27) ng/L, (2.02±0.81) μg/L, respectively, and the differences between the two groups were significant ( P<0.001, P<0.001, P<0.001, P<0.001, P=0.003). After the intervention, the level of IgA(1.92±0.63) g/L, IgG(11.36±1.26) g/L, IgM(2.01±0.57) g/L in the observation group was higher than that in the control group (1.62±0.49), (9.58±1.23), (1.60±0.47) g/L, respectively, and the differences between the two groups were significant ( P=0.020, <0.001, =0.001, respectively). In the observation group, the hospital stay(12.1±1.7) d, postoperative ambulation time (1.9±0.6) d and exhaust time (3.1±0.4) d was less than that in the control group(17.2±2.4) d, (2.8±1.0) d, (4.2±0.8) d, respectively, and there were significant differences between two groups(all P<0.001). The postoperative complication rate of 5.0%(2/40) in the observation group was significantly lower than 25.0%(10/40) in the control group (χ 2=6.275, P=0.012). Conclusion:The patients with radiation enteritis and intestinal obstruction treated by conventional surgery were given eras intervention, which improved the nutritional level, immune function and inflammatory stress reaction of the patients, improved the treatment effect of the patients, and shortened the hospitalization time.
ABSTRACT
Objective:To explore the clinical effect of intestinal obstruction catheter in patients with tuberculous peritonitis complicated with intestinal obstruction and its influence on inflammatory factors.Methods:Sixty-two patients of tuberculous peritonitis with intestinal obstruction were admitted to the general surgery department of the Eighth Medical Center of Chinese PLA General Hospital from June 2015 to January 2020 in this prospective study.According to the method of digital table, cases were randomly divided into control group and treatment group, 31 cases in each group.The control group was given conventional treatment, while the treatment group was treated with intestinal obstruction catheter on the basis of conventional treatment.The clinical indexes such as abdominal pain relief time, antipyretic time, exhaust time, gas-liquid level disappearance time and hospitalization time were compared between the two groups.According to the levels of C-reactive protein(CRP), Interleukin-6(IL-6), Interleukin-8(IL-8) and Interferon-γ(IFN-γ), the inflammatory stress state of the two groups before and after treatment was compared.The changes of gastrin, motilin, vasoactine intrestinal peptide(VIP) were compared between the two groups before and after treatment.Results:The time to relieve abdominal pain(2.08±1.17) d, the time to reduce fever(3.36±1.89) d, the time to exhaust gas(2.12±1.45) d, the time to disappear gas-liquid level(2.58±1.61) d and the time to stay-in-hospital(9.22±2.13) d in the observation group, and those in the control group were (6.26±2.52), (5.68±2.44), (6.18±2.24), (7.34±2.23), (17.49±3.46) d, respectively.The difference between the two groups was statistically significant( P=0.013, 0.024, 0.035, 0.014 and 0.002, respectively). Before treatment, CRP, IL-6, IL-8, IFN-γ in the control group were (105.62±11.96) mg/L, (657.31±49.67) ng/L, IL-8 (463.53±31.74) ng/L and (47.24±9.66) ng/L , and (106.07±12.03) mg/L, (678.46±51.19) ng/L, (471.68±32.03) ng/L and (46.84±9.28) ng/L in the observation group respectively, and there were no significant differences between the two groups before treatment ( P>0.05). After treatment, CRP, IL-6, IL-8, IFN-γ were (86.25±9.16) mg/L, (373.25±24.18) ng/L, (211.26±20.83) ng/L and (35.42±7.52) ng/L in the control group, and (53.72±7.68) mg/L, (184.27±16.92) ng/L, (82.51±11.35) ng/L and (19.65±3.46) ng/L in the observation group, respectively.After treatment, there were significant differences in the indicators between the two groups ( P=0.021, 0.015, 0.029, 0.011, respectively). There was no difference in the levels of gastrin((180.89±21.17) vs(192.32±21.69) ng/L), motilin((336.73±7.23) vs(357.46±7.29) ng/L) and VIP((102.87±13.49) vs(109.31±13.53)pg/L) between the observation and control group before treatment( P>0.05, respectively). After treatment, the levels of gastrin(65.57±8.72) ng/L, motilin(135.71±14.38) ng/L and VIP(55.07±7.15) pg/L in the observation group were lower than those in the control group((110.35±13.86) ng/L, (231.93±21.95) ng/L, (81.56±10.59) pg/L, respectively), and the differences were statistically significant( P=0.013, 0.021 and 0.014, respectively). Conclusion:Intestinal obstruction catheter can effectively improve the clinical effect, reduce the inflammatory stress response, and promote the recovery of gastrointestinal function in patients with tuberculous peritonitis complicated with intestinal obstruction.

ABSTRACT
Objective To evaluate diagnosis and surgical treatment of carotid body tumors.Methods It was retrospectively reviewed that the diagnostic approaches, surgical operation methods and its related complications in 70 carotid body tumor cases treated in our hospital from May 1986 to May 2008.Results Diagnosis was established by computer tomography angiography (CTA) or magnetic resonance angiography (MRA). Surgical excision was successfully performed in 63 cases with 72 tumours. There were no postoperative deaths. Two cases developed hemiplegia following surgery. Temporary cranial nerve palsy occurred in 17 cases while permanent nerve palsy occurred in 4 cases. Sixty-two cases were followed-up from 6 months to 5 years. There were no deaths in operative cases, with local tumor recurrence in 2 cases and 3 cases died due to remote metastasis. Conclusion CTA or MRA is sufficient for the diagnosis and preoperative assessment of carotid body tumor and its related structures. Surgical modality should be adjusted according to the relationship between the tumor and the carotid artery. Full exposure of the surgical area,careful control of intraoperative bleeding and persistent maintainance of blood flow to the brain are important measures for successful surgery.
ABSTRACT
Objective To reduce information loss in the refining processing of photoplethysmographic (PPG) pulse waveform. Method A novel PPG pulse waveform refining processing technique, named truncation/extrapolation technique was proposed. The key point of the proposed technique was to preserve the shape pattern of the most significant parts of the waveform at the expense of the distortion of the insignificant part. Thus, as compared with the conventional time-normalization method, the proposed technique ensured the accumulation coherent of the signal energy could be. Result Waveform analysis and comparison of experimental data between two methods verified the effectiveness of the proposed method in maintaining the most significant time domain features of the pulse waveform over a relatively wide range of the heart rate change, especially the shape and width of the dominant peak and the position of the dicrotic notch of the first derivative of PPG(dPPG). Conclusion The proposed method reduces the information loss in PPG pulse waveform refining processing, thus helps further processing of the PPG signal using some advanced signal processing techniques, such as waveform modeling and pattern recognition.
