ABSTRACT

Objective:To investigate the prognostic factors for the risk of prolonged postoperative ileus (PPOI) after colorectal cancer resection.Methods:The clinical data of 896 patients undergoing radical colorectal cancer resection at Affiliated Hospital of Qingdao University between Jan 2016 and Dec 2022 were retrospectively analyzed. Patients were divided into PPOI group (59 cases) and non-PPOI group (837 cases) according to whether PPOI happened after surgery. Potential prognostic factors for the risk of developing PPOI were analyzed by univariate and multivariate Logistic regression. The receiver operating characteristic curve analysis was performed to assess the predictive power of potential prognosis factors.Results:Fifty-nine patients (6.5%) developed PPOI after radical colorectal cancer resection. Univariate and multifactorial logistic regression analyses showed that diabetes mellitus ( OR=2.360, P=0.018), preoperative albumin level <35 g/L ( OR=2.196, P=0.036), postoperative epidural analgesia ( OR=2.399, P=0.007), open surgery ( OR=3.413, P=0.001), and ICU hospitalization ≥ 48 h ( OR=6.134, P<0.001) were independent prognostic factors for PPOI. Combining the above prognostic factors to construct the receiver operating characteristic curve yielded an area under the curve of 0.806 (95% CI: 0.698-0.838), with an accuracy, sensitivity and specificity of 73.9%, 74.0%, 72.9%, respectively. Conclusion:Diabetes mellitus, preoperative albumin level, postoperative epidural analgesia, open surgery, and ICU hospitalization ≥ 48 h were risk factors for PPOI after radical colorectal cancer resection.

ABSTRACT

OBJECTIVE@#To investigate the clinical value of analgesia and sedation under bispectral index (BIS) monitoring combined with hydraulic coupled intracranial pressure (ICP) monitoring in severe craniocerebral injury (sTBI).@*METHODS@#(1) A prospective self-controlled parallel control study was conducted. A total of 32 patients with sTBI after craniotomy admitted to the intensive care unit (ICU) of the First People's Hospital of Huzhou from December 2020 to July 2021 were selected as the research objects. ICP was monitored by Codman monitoring system and hydraulically coupled monitoring system, and the difference and correlation between them were compared. (2) A prospective randomized controlled study was conducted. A total of 108 sTBI patients admitted to the ICU of the First People's Hospital of Huzhou from August 2021 to August 2022 were selected patients were divided into 3 groups according to the random number table method. All patients were given routine treatment after brain surgery. On this basis, the ICP values of the patients in group A (35 cases) were monitored by Codman monitoring system, the ICP values of the patients in group B (40 cases) were monitored by hydraulic coupling monitoring system, and the ICP values of the patients in group C (33 cases) were monitored combined with hydraulic coupling monitoring system, and the analgesia and sedation were guided by BIS. The ICP after treatment, cerebrospinal fluid drainage time, ICP monitoring time, ICU stay time, complications and Glasgow outcome score (GOS) at 6 months after surgery were compared among the 3 groups. In addition, patients in group B and group C were further grouped according to the waveforms. If P1 = P2 wave or P2 and P3 wave were low, they were classified as compensatory group. If the round wave or P2 > P1 wave was defined as decompensated group, the GOS scores of the two groups at 6 months after operation were compared.@*RESULTS@#(1) There was no significant difference in ICP values measured by Codman monitoring system and hydraulic coupling monitoring system in the same patient (mmHg: 11.94±1.76 vs. 11.88±1.90, t = 0.150, P = 0.882; 1 mmHg≈0.133 kPa). Blan-altman analysis showed that the 95% consistency limit (95%LoA) of ICP values measured by the two methods was -4.55 to 4.68 mmHg, and all points fell within 95%LoA, indicating that the two methods had a good correlation. (2) There were no significant differences in cerebrospinal fluid drainage time, ICP monitoring time, ICU stay time, and incidence of complications such as intracranial infection, intracranial rebleeding, traumatic hydrocephalus, cerebrospinal fluid leakage, and accidental extubation among the 3 groups of sTBI patients (P > 0.05 or P > 0.017). The ICP value of group C after treatment was significantly lower than that of group A and group B (mmHg: 20.94±2.37 vs. 25.86±3.15, 26.40±3.09, all P < 0.05), the incidence of pulmonary infection (9.1% vs. 45.7%, 42.5%), seizure (3.0% vs. 31.4%, 30.0%), reoperation (3.0% vs. 31.4%, 40.0%), and poor prognosis 6 months after operation (33.3% vs. 65.7%, 65.0%) were significantly lower than those in group A and group B (all P < 0.017). According to the hydraulic coupling waveform, GOS scores of 35 patients in the compensated group were significantly higher than those of 38 patients in the decompensated group 6 months after operation (4.03±1.18 vs. 2.39±1.50, t = 5.153, P < 0.001).@*CONCLUSIONS@#The hydraulic coupled intracranial pressure monitoring system has good accuracy and consistency in measuring ICP value, and it can better display ICP waveform changes than the traditional ICP monitoring method, and has better prediction value for prognosis evaluation, which can replace Codman monitoring to accurately guide clinical work. In addition, analgesia and sedation under BIS monitoring combined with hydraulic coupled ICP monitoring can effectively reduce ICP, reduce the incidence of complications, and improve the prognosis, which has high clinical application value.

ABSTRACT

Objective:To explore the link between the differentially expressed long non-coding RNAs (lncRNAs) and the number of regulatory T cells (Tregs) by detecting the lncRNAs expression profiles in patients with systemic lupus erythematosus (SLE), then analyze the correlation between Tregs and lncRNAs and the clinical features of SLE patients. We also predict the mechanism by which lncRNAs regulate the differentiation and development of Tregs, and provid new approach for the treatment of SLE.Methods:Peripheral blood of 9 active SLE patients was collected and mononuclear cells (PBMCs) were extracted. The lncRNAs expression profiles of PBMCs was analyzed by whole transcriptome sequencing. Nine healthy people served as controls to screen the differentially expressed lncRNAs, and to analyze the correlation between lncRNAs and Tregs number. Pearson test was used to analyze the correlation between lncRNA and the number of Tregs, and the correlation between Treg-associated lncRNAs and systemic lupus erythematosus disease activity index(SLEDAI) score, erythrocyte sedimentation rate (ESR), C3, C4 in SLE patients. The targeted genes of Treg asso-ciated lncRNAs were predicted with miRcode and Targetscan databases and co-expression network.Results:There were 240 differentially expressed lncRNAs in SLE patients compared with healthy controls, including 134 highly expressed lncRNAs ( P<0.05) and 106 low expressed lncRNAs ( P<0.05). The expression of ANKRD44-AS1 ( r=0.74, P=0.022), LINC00200 ( r=0.70, P=0.037), AP001363.2 ( r=0.78, P=0.014) and LINC02824 (r=0.79, P=0.011) were positively correlated with the number of Tregs, and the expression of AP000640.1 ( r=-0.72, P=0.028), AC124248.1 ( r=-0.77, P=0.016), LINC00482 ( r=-0.83, P=0.005) and MIR503HG ( r=-0.96, P<0.001) were negatively correlated with the number of Tregs. Among these eight Tregs associated lncRNAs, the expression of LINC00482 ( r=-0.73, P<0.001) and MIR503HG ( r=-0.76, P<0.001) were negatively correlated with C3. LINC00200, ANKRD44-AS1 and AP000640.1 related to Tregs regulated the expression of STAT5, PLD1, HOPX and RUNX3 through competitively binding of miRNA or transregulatory mechanism, thereby regulating the differentiation and development of Tregs. Conclusion:The lncRNAs expression profiles are changed in SLE patients, the differentially expressed lncRNAs are associated with abnormal number and function of Tregs in SLE patients, and Treg associated lncRNAs are associated with SLE disease activity, which may affect the expression of STAT5, PLD1, HOPX, RUNX3 and regulate Tregs function and participate in the pathogenesis and progression of SLE by competitively binding to miRNAs or trans-regulatory mechanism.

ABSTRACT

Objective:To investigate the application value of pre-suture craniotomy combined with intracranial pressure monitoring in surgery for posttraumatic acute diffuse brain swelling (PADBS).Methods:One hundred and fifty-seven patients with PADBS admitted to our hospital from February 2015 to December 2019 were chosen in our study; 68 patients (control group), admitted to our hospital from February 2015 to June 2017, underwent controlled decompression under intracranial pressure monitoring; and 89 patients (treatment group), admitted to our hospital from June 2017 to December 2019, were performed pre-suture craniotomy combined with controlled decompression under intracranial pressure monitoring. The craniotomy time, brain tissue exposure time, cranial closure time, incidence of acute encephalocele, and Glasgow outcome scale (GOS) scores at 6 months after injury were retrospectively analyzed and compared between the two groups.Results:As compared with those in the control group, the patients in the treatment group had significantly longer intraoperative craniotomy time ([19.2±1.6] min vs. [15.4±1.4] min), significantly shorter exposure time of brain tissues ([18.5±2.4] min vs. [26.3±2.2] min), significantly shorter time of cranial closure ([11.2±1.5] min vs. [18.3±2.1] min), and statistically lower incidence of acute encephalocele (22.5% vs. 38.2%), P<0.05). The good prognosis rate of the treatment group (70.8%) was significantly higher than that of the control group (50.0%), and the mortality rate (6.7%) was statistically lower than that of the control group (17.6%, P<0.05). Conclusion:Pre-suture craniotomy combined with controlled decompression under intracranial pressure monitoring can shorten the time of cranial closure and brain tissue exposure, reduce the incidence of acute encephalocele, and ultimately improve the prognosis of patients with posttraumatic acute diffuse brain swelling.

ABSTRACT

Objective:To investigate the effect of decompression of optic nerve canal for traumatic optic neuropathy (TON) via lateral supraorbital approach.Methods:A retrospective case series study was performed to analyze clinical data of 23 TON patients admitted to First People's Hospital of Huzhou from December 2013 to June 2019. There were 16 males and 7 females, aged 17-51 years [(34.3±2.2)years]. Degree of visual impairment included count fingers in 4 patients, hand motion in 4, light perception in 9 and loss of light perception in 6. Visual evoked potential examination (VEP) was performed in 15 patients before surgery. The amplitude of P100 completely disappeared in 5 patients, and the amplitude of P100 was lower than the lower limit of normal value and the latency prolonged in 10 patients. The time from injury to operation was 3 h-14 days [(3.3±0.6)days]. All patients underwent decompression of optic nerve canal via supralateral orbital approach, and dural repair was performed simultaneously in 11 patients with dural rupture. Intraoperative fractures and meningeal tears, duration of operation, blood loss, and hospitalization duration were recorded. Combined with the classical visual acuity improvement assessment method and the World Health Organization (WHO) low vision and blind grading standard, visual acuity was compared before operation, at 10 days and 3 months after operation. Glasgow Coma Scale (GCS) was used to evaluate patients' state of consciousness in the course of the disease. Glasgow Outcome Scale (GOS) was used to evaluate the prognosis. Incidence of complications was observed as well.Results:All patients were followed up for 12-16 weeks [(13.5±2.4)weeks]. Intraoperative microscopic exploration revealed that all patients had optic nerve canal fracture, 3 patients had frontal fracture with dural rupture, and 8 patients had ethmoid bone fragment with anterior skull base dural rupture. The duration of operation was 108.5-224.3 minutes [(151.8±30.2)minutes], including (32.5±8.4)minutes for craniotomy. The intraoperative blood loss was 90.5-165.3 ml [(121.3±15.5)ml]. The hospitalization was 14-26 days [(19.7±3.4)days]. The visual acuity of 13 patients (57%) improved and 5 patients (39%) relieved from blindness 10 days after operation, showing significant difference compared with the preoperation ( P<0.05). The visual acuity of 17 patients (74%) improved and 9 patients (39%) relieved from blindness at 3 months after operation. There was significant difference in visual acuity examined between 10 days and 3 months after operation ( P<0.05). Six patients were invalid, and 4 of them had no light perception before operation and the amplitude of VEP examination completely disappeared. All patients had GCS of 15 when left the hospital and GOS of 5 at 3 months after operation. One patient had cerebrospinal fluid rhinorrhea and healed after 7 days of supine position. No secondary hematoma, epilepsy or intracranial infection occurred during follow-up. Conclusion:Optic canal decompression via the lateral supraorbital approach can improve visual acuity in early stage and increase the rate of out of blindness, with low postoperative complications and satisfactory functional recovery, which is worthy of clinical application.

ABSTRACT

Objective:To analyze the clinical efficacy of prednisone, hydroxychloroquine (HCQ) combined with plasmapheresis (PE) or not for the treatment of systemic lupus erythematosus (SLE) during pregnancy.Methods:Fourteen patients with SLE during pregnancy were analyzed. Totally 7 patients in the non-PE group were given prednisone and HCQ only while 7 patients in PE group were given prednisone and HCQ combined with PE. The fetus outcomes and clinical data, such as erythrocyte sedimentation tate (ESR), urine protein level, blood cell count and systemic lupus erythematosus disease activity index (SLEDAI) score before and after treatment at 3, 6, 12 months were used to evaluate the efficacy between the two groups. The comparison between groups was performed by repeated measures analysis of varianc (ANOVA).Results:Totally 11 patients delivered successfully in both groups while three of the 7 patients in the non-PE group had stillbirth. The 11 fetuses developed well and were born with an Apgar score of 8 or more at birth in both groups. There was a significant difference in ESR and platelet counts between the two groups ( F=7.838, P<0.05 ; F=32.269 , P<0.05). The ESR of the PE group was lower than that in the non-PE group at 3, 6 and 12 months after delivery, while the platelet count was higher than that in the non-PE group. Although there was no significant difference in the SLEDAI scores between the two groups ( F=2.816, P=0.119), the average of SLEDAI scores in the PE group was lower than that in the non-PE group at 3, 6 and 12 months after delivery. In addition, the urine protein of 7 patients in the PE group turned negative at 6, 12 months after delivery. In the non-PE group, urinary protein-positive patients were present in 3, 6, 12 months after delivery. Conclusion:PE in combination with oral prednisone and HCQ is a more effective than oral prednisone and HCQ alone for patients with active SLE during pregnancy, which reduces pregnancy loss and promote the patient's outcome.

ABSTRACT

Objective To explore the role of continuous pulse output (PICCO) monitoring in treatment of patients with traumatic acute diffuse brain swelling (PADBS). Methods Eighty-six PADBS patients, admitted to our hospital from January 2014 to October 2017, were routinely given brain invasive intracranial pressure (ICP) monitoring after admission. At the same time, the patients were given bone flap decompression and hematoma clearance according to the condition of the diseases. After surgery, according to the wishes of family members, patients were divided into two groups (n=43):patients from treatment group accepted PICCO monitoring on the basis of ICP monitoring, and the treatment plan was adjusted according to the monitoring results; and the treatment plan in patients from control group was adjusted according to traditional central venous pressure (CVP) monitoring results on basis of ICP monitoring. Results One week after operation, the ICP in the treatment group was (14.36±2.82) mmHg when the cerebral perfusion pressure (CPP) was controlled between 50 and 70 mmHg, which was significantly different from the ICP in the control group (18.58±2.25) mmHg (P<0.05). Two weeks after treatment, Glasgow Coma Scale (GCS) scores of the treatment group (10.87±1.72) were significantly higher than those of the control group (8.18±1.16, P<0.05). The incidences of posttraumatic cerebral infarction (PTCI) and neurogenic pulmonary edema (NPE) in the treatment group (11.6%, 18.6%) were significantly lower than those of the control group (25.6%, 34.9%, P<0.05); the recovery rate (76.7%) in the treatment group was significantly higher than that in the control group (60.5%, P<0.05); the mortality rate (9.3%) was significantly lower than that in the control group (18.6%, P<0.05). Conclusion On the basis of intraventricular ICP monitoring, combined PICCO monitoring can effectively control ICP, improve cerebral perfusion, reduce the incidence of PTCI and NPE, improve the prognosis, and reduce the mortality in PADBS patients.

ABSTRACT

OBJECTIVE To observe and compare the cytotoxicity induced by andrographolide (AD)and its water soluble derivatives:andrographolide sodium bisulfite(ASB),active pharmaceutical ingredients of Chuanhuning and Yanhuning on human renal tubular epithelial cells (HK-2),and to explore the ASB-induced endoplasmic reticulum stress(ERS)mechanism. METHODS HK-2 cells were treated with the above four drugs respectively. The survival rate was examined by methyl thiazolyltetrazolium (MTT) assay and 50% inhibitory concentration (IC50) was calculated. In ASB treated group, Hoechst33342 staining and flow cytometry analysis were used to determine cell apoptosis, intracellular superoxide dismutase(SOD)activity and malondialdehyde(MDA)content were examined, and the protein expressions of binding immunoglobulin protein (Bip),C/EBP-homologous protein (CHOP)and cysteine-containing aspartate-specific protease 4(caspase 4)were detected by Western blotting. RESULTS The four drugs inhibited HK-2 cell growth in a time-dependent and concentration-dependent manner. At 24 h,the IC50 of AD (30.6 μmol · L- 1) was lower than that of others. Active pharmaceutical ingredients of Chuanhuning and Yanhuning (16.2 and 15.6 mmol · L- 1) were very close,ASB was 29.4 mmol · L-1. ASB(0,15,30 and 60 mmol · L-1)increased the apoptotic rate and caused the decrease in SOD activity and the increase in MDA content in a dose-dependent manner. Compared with control group,the protein expression of CHOP increased (P<0.01) at 8 h with ASB (30 and 60 mmol · L-1)treatment,Bip and caspase 4 had no significant change. In addition,at 24 h, ASB(60 mmol·L-1) decreased the expression of Bip(P<0.05),ASB(30 and 60 mmol·L-1)promoted the expression of CHOP(P<0.01),and the protein expression of activated caspase 4 increased in a concentration-dependent manner(P<0.01). CONCLUSION AD and its water soluble derivatives have a toxic effect on HK-2 cells. CHOP and caspase 4 pathway related to ERS is involved in ASB-induced apoptosis.

ABSTRACT

It has been found by sorting out and analyzing ancient and modern doctors’ green tortoise exploring point acupuncture manipulation that ancient and modern doctors use Xu Feng's manipulation as the foundation and make some innovations on that b asis and according to their own clinical experiences. The clinical application range of different doctors’ green tortoise exploring point acupuncture manipulation is proposed by summarizing recent over 10 years’ clinical reports and the authors’ clinical practice. It is considered that the shortcomings of green tortoise exploring point acupuncture manipulation are lack of manipulation standardization and modern mechanism study and that manipulation standardization should be closely connected with clinical practice for further application and popularization.

ABSTRACT

<p><b>OBJECTIVE</b>To compare the effectiveness of percutaneous microwave ablation ( MWA) versus hepatectomy for multifocal hepatocellular carcinoma.</p><p><b>METHODS</b>From August 2002 to March 2012, one hundred and twenty-two patients with multifocal hepatocellular carcinoma (diameters 1 to 7 cm, 2 to 4 lesions) were treated by either complete MWA or radical hepatectomy, and their clinical data were collected and analyzed.The patients were divided into MWA group (n = 50) and resection group (n = 72), and the resection group was matched by MWA group based on clinical parameters. The survival and complications in the two groups were compared.</p><p><b>RESULTS</b>The overall 1-, 3- and 5-year survival rates were 100.0%, 73.0% and 62.0%, respectively, in the MWA group, and 80.0%, 56.0%, and 41.0%, respectively, in the resection group (P < 0.05). The corresponding recurrence-free survival rates were 88.0%, 63.0%, and 52.0% in the MWA group, and 68.0%, 45.0%, and 36.0%, respectively, in the resection group (P< 0.05). The multivariate Cox regression analysis indicated that albumin level, performance status, treatment modality, and tumor size were independent prognostic factors.</p><p><b>CONCLUSION</b>Compared with hepatectomy, percutaneous microwave ablation is a minimally invasive and reproducible procedure, and can improve the survival in patients with multifocal hepatocellular carcinoma.</p>

ABSTRACT

OBJECTIVE To investigate the effect of injection of β2-adrenergic receptor agonist clenbuterol into the infralimbic cortex(IL) on drug-seeking behavior triggered by conditioned cues. METHODS Adult male SD rats were trained to self-administer heroin under a FR1 schedule for consecutive 14 d,followed by 2-h extinction training. Cue-induced heroin seeking was measured for 2 h. Clenbuterol was microinjected bilaterally into the IL(8 ng/side)of rats 15 min prior to reinstatement test. Meanwhile,locomotor activity was detected 15 min after clenbuterol or artifial cerebrospinal fluid(mod?el group) was microinjected bilaterally into IL. Western blotting was used to detect the expression of phosphorylated cyclic AMP response element-binding protein(p-CREB)in the prelimbic cortex(PL), IL,nucleus accumbens core (NACc) and shell (NACsh) of rats immediately after reinstatement test. RESULTS After heroin administration training for 14 consecutive days,these animals exhibited reliable heroin self-administration,indicated by the increase in active nose poke responses and infusions. The rats that had received infusion of clenbuterol into the IL had significantly lower active pokes (8 ± 3)than those in model group(45±10)in cue-induced reinstatement(P<0.01),but there was no significant differ?ence between clenbuterol group and vehicle group in the locomotor activity. The expression of p-CREB in either IL or NACsh was significantly decreased in clenbuterol group compared with model group(P<0.01,P<0.05),but significantly increased in NACc(P<0.01). CONCLUSION Microinjection of clenb?uterol into the IL can attenuate the cue-induced reinstatement of heroin-seeking behavior in rats. The underlying mechanism might be related to the regulation of p-CREB expression in the NACc and NACsh.

ABSTRACT

Objective To investigate the correlation of vertebral artery dominance (VAD) with incidence and laterality of posterior circulation infarct,and observe the correlation of VAD and basal artery (BA) curvature.Methods Total incidence of posterior circulation infarcts,incidence of separate territory infarcts in posterior circulation and incidence of BA curvature were compared between 68 VAD patients and 66 controls.VA dominance,laterality of BA curvature and separate territory infarcts,and their directional relationships were observed in VAD group.Results The total incidence of posterior circulation infarcts in VAD group was significantly higher than that in controls(45.6% (31/68) vs 21.2% (14/66),x2 =8.922,P =0.003 ).The incidences of posterior inferior cerebellar artery (PICA) territory infarct and BA territory infarct were both significantly higher than that in controls ( 11.8% ( 8/68 ) vs 0,x2 =8.250,P =0.004 ;20.6% (14/68) vs 7.6% (5/66),x2 =4.660,P =0.031 ).No differences were found in superior cerebellar artery (SCA) and posterior cerebral artery ( PCA ) territory infarcts between two groups.87.5 % (7/8) PICA infarcts were on the opposite side of dominant VA.42.9% (6/14) BA infarcts were on the side of dominant VA.The incidence of BA curvature was significantly higher than that in controls(50.0% (34/68) vs 9.1% (6/66),x2 =26.768,P =0.000 ).No differences were found in the incidences of posterior circulation infarcts between BA curvature patients and BA straight patients(52.9% (18/34) vs 38.2% ( 13/34),x2 =1.482,P =0.223 ).97.1% (33/34)patients had an opposite directional relationship between dominant VA and BA curvature in 37 BA curvature patients in VAD group.Conclusions The incidence of posterior circulation infarcts is higher in VAD patients,especially in PICA infarct and BA infarct patients.Most PICA infarcts occurred on the opposite side of dominant VA.The incidence of BA curvature is higher in VAD patients,and BA usually bends to the opposite side of dominant VA.
