Objective To explore the effects of community-based comprehensive intervention on social function and quality of life of patients with bipolar disorder. Methods 244 bipolar disorder patients were assigned into control group (n=119) and intervention group (n=125). The control group accepted antipsychotics only, and the intervention group accepted community-based comprehensive intervention in addition. They were assessed with Social Disability Screening Schedule (SDSS) and Generic Quality of Life Inventory-74 (GQOLI-74) before and 6, 12 months after treatment. Results The SDSS score was lower (P<0.05) and the GQOLI-74 score was higher (P<0.05) in the intervention group than in the control group. Conclusion Community-based comprehensive intervention can improve the social function and quality of life of patients with bipolar disorder.

Objective To observe the effect of different airway pressure on ventilation, organ perfusion and return of spontaneous circulation (ROSC) of cardiac arrest (CA) pigs during cardiopulmonary resuscitation (CPR), and to explore the possible beneficial mechanism of positive airway pressure during CPR. Methods Twenty healthy landrace pigs of clean grade were divided into low airway pressure group (LP group, n = 10) and high airway pressure group (HP group, n = 10) with random number table. The model of ventricular fibrillation (VF) was reproduced by electrical stimulation, and mechanical chest compressions and mechanical ventilation (volume-controlled mode, tidal volume 7 mL/kg, frequency 10 times/min) were performed after 8 minutes of untreated VF. Positive end expiratory pressure (PEEP) in LP group and HP group was set to 0 cmH2O and 6 cmH2O (1 cmH2O = 0.098 kPa) respectively. Up to three times of 100 J biphasic defibrillation was delivered after 10 minutes of CPR. The ROSC of animals were observed, and the respiratory parameters, arterial and venous blood gas and hemodynamic parameters were recorded at baseline, 5 minutes and 10 minutes of CPR. Results The number of animals with ROSC in the HP group was significantly more than that in the LP group (8 vs. 3, P < 0.05). Intrathoracic pressure during chest compression relaxation was negative in the HP group, and its absolute value was significantly lower than that in LP group at the same time [intrathoracic negative pressure peak (cmH2O): -4.7±2.2 vs. -10.8±3.5 at 5 minutes, -3.9±2.8 vs. -6.5±3.4 at 10 minutes], however, there was significantly difference only at 5 minutes of CPR (P < 0.01). Intrathoracic pressure variation during CPR period in the HP group were significantly higher than those in the LP group (cmH2O: 22.5±7.9 vs. 14.2±4.4 at 5 minutes, 23.1±6.4 vs. 12.9±5.1 at 10 minutes, both P < 0.01). Compared to the LP group, arterial partial pressure of oxygen [PaO2 (mmHg, 1 mmHg = 0.133 kPa): 81.5±10.7 vs. 68.0±12.1], venous oxygen saturation (SvO2: 0.493±0.109 vs. 0.394±0.061) at 5 minutes of CPR, and PaO2 (mmHg: 77.5±13.4 vs. 63.3±10.5), arterial pH (7.28±0.09 vs 7.23±0.11), SvO2 (0.458±0.096 vs. 0.352±0.078), aortic blood pressure [AoP (mmHg): 39.7±9.5 vs. 34.0±6.9], coronary perfusion pressure [CPP (mmHg): 25.2±9.6 vs. 19.0±7.6], and carotid artery flow (mL/min:44±16 vs. 37±14) at 10 minutes of CPR in the HP group were significantly higher (all P < 0.05). Arterial partial pressure of carbon dioxide (PaCO2) in the HP group was significantly lower than that in the LP group at 10 minutes of CPR (mmHg: 60.1±9.7 vs. 67.8±8.6, P < 0.05). Conclusions Compared to low airway pressure, a certain degree of positive airway pressure can still maintain the negative intrathoracic pressure during relaxation of chest compressions of CPR, while increase the degree of intrathoracic pressure variation. Positive airway pressure can improve oxygenation and hemodynamics during CPR, and is helpful to ROSC.

Objective To approach the predictive value of continuous monitoring end-tidal carbon dioxide partial pressure (PETCO2) on the outcome of in-hospital cardiopulmonary resuscitation (CPR), and explored the indicators of termination of resuscitation. Methods A secondary analysis of a multicenter observational study data was conducted. The screening aim was adult non-traumatic in-hospital CPR patients whose PETCO2were recorded within 30 minutes of CPR. Clinical information was reviewed. The mean PETCO2in restoration of spontaneous circulation (ROSC) and non-ROSC patients was recorded. The outcome of CPR was continuously assessed by PETCO2≤ 10 mmHg (1 mmHg = 0.133 kPa) for 1, 3, 5, 8, 10 minutes. Receiver operating characteristic (ROC) curve was plotted, and the predictive value of PETCO2≤ 10 mmHg for different duration on the outcome of CPR was evaluated. Results A total of 467 recovery patients, including 419 patients with complete recovery were screened. Patients who were out-of-hospital resuscitation, non-adults, traumatic injury, had no PETCO2value, PETCO2value failed to explained the clinical conditions, or patients had not monitored PETCO2within 30 minutes of resuscitation were excluded, and finally 120 adult patients with non-traumatic in-hospital resuscitation were enrolled in the analysis. The mean PETCO2in 50 patients with ROSC was significantly higher than that of 70 non-ROSC patients [mmHg: 17 (11, 27) vs. 9 (6, 16), P < 0.01]. ROC curve analysis showed that the area under ROC curve (AUC) of PETCO2during the resuscitation for predicting recovery outcome was 0.712 [95% confidence interval (95%CI) = 0.689-0.735]; when the cut-off was 10.5 mmHg, the sensitivity was 57.8%, and the specificity was 78.0%, the positive predictive value (PPV) was 84.6%, and negative predictive value (NPV) was 46.9%. The duration of PETCO2≤ 10 mmHg was used for further analysis, which showed that with PETCO2≤10 mmHg in duration, the prediction of the sensitivity of the patients failed to recover decreased from 58.2% to 28.2%, but specificity increased from 39.4% to 100%; PPV increased from 40% to 100%, and NPV decreased from 57.5% to 34.2%. Conclusion For adult non-traumatic in-hospital CPR patients, continuous 10 minutes PETCO2≤10 mmHg may be an indicate of termination of CPR.

OBJECTIVE：To investigate the effects of parecoxib sodium ，flurbiprofen axetil and lornoxicam combined with patient controlled intravenous analgesia （PICA） on postoperative analgesia in patients undergoing gynecological laparoscopic surgery and its effect on serum related factors. METHODS ：A total of 280 patients who underwent gynecologic laparoscopic surgery in the Second Affiliated Hospital of Hainan Medical University from Mar. 2017 to Mar. 2019 were randomly divided into control group （group C ），parecoxib sodium group （group P ），and flurbiprofen axetil group （group F ）and lornoxicam group （group L ）acording to random number table ，with 70 patients in each group. Four groups of patients received Sodium chloride injection 5 mL，Parecoxib sodium for injection 40 mg，Flurbiprofen axetil injection 50 mg and Lornoxicam for injection 8 mg （added 8 mg when the effect was not good ）intravenously at 30 min before the end of surgery. At the end of surgery ，they were given PICA of Sufentanil citrate injection and Dizosin injection for analgesia. The situation of pain and nausea symptom were evaluated at 6，12，24 and 48 h after surgery by using numerical rating scale （NRS）. The levels of serum CRP ，IL-6，SP and PGE 2 were detected by chemiluminescence method and ELISA. The times of pressing PICA pump and the dosage of analgesic were recorded in 4 groups within 24 h after surgery. The ADRs of patients within 48 h after surgery were recorded ，such as bloating ， dizziness，itchy skin ，respiratory depression and urinary retention. RESULTS ：At different time points ，the NRS scores of pain of group P ，F and L were significantly lower than those of group C ；and 48 h after surgery ，NRS score of pain of group L was significantly lower than those of group P and F （P＜0.05）. There was no statistical significance in the level of CRP ，IL-6，SP and PGE2 of 4 groups before surger （P＞0.05）. The CRP ，IL-6，SP and PGE 2 levels at each time point after surgery of group P ，F and L were significantly lower than those of group C ；compared with group P ，serum level of SP at 48 h after surgery as well as serum levels of PGE 2 at 12，24 and 48 h after surgery were significantly decreased in group F ，and serum level of IL- 6 at 48 h after surgery，serum levels of SP at 24 and 48 h after surgery ，serum levels of PGE 2 at 12，24，48 h after surgery were decreased significantly in group L ；compared with group F ，serum level of SP at 48 h after surgery as well as serum levels of PGE 2 at 12， 24，48 h after surgery were all decreased significantly in group L （P＜0.05）. There was no statistical significance in the incidence of anausea and vomiting among 4 groups（P＞0.05）. CONCLUSIONS ：Parecoxib sodium ，flurbiprofen axetil and lornoxicam combined with PICA can effectively relieve the pain of patients after gynecological laparoscopic surgery and reduce the levels of serum related factor ，and lornoxicam has the most obvious effect.

ObjectiveAfter the brain and heart injuries were simulated by myocardial injury caused by acute cerebral ischemia， this study explored the mechanism of Naoxintong capsules in treating brain and heart injuries under cerebral ischemia state with Toll-like receptor （TLR） 2/TLR4 as the breakthrough point. MethodC57BL/6 male mice were randomly assigned into the sham operation， model， Naoxintong， and Ginaton groups. The middle cerebral artery occlusion （MCAO） method was used to establish a mouse model of cerebral ischemia. The neuroethological score， cerebral infarction area， cell apoptosis， ionized calcium-binding adaptor molecule 1 （IBA-1）-positive microglia proportion， and serum levels of N-terminal pro-brain natriuretic peptide （NT-proBNP）， creatine kinase-MB （CK-MB）， and lactic dehydrogenase （LDH） were determined to evaluate the pharmacodynamic effects of Naoxintong capsules on heart and brain injuries after cerebral ischemia in mice. Western blotting was employed to determine the expression of TLR2/TLR4 protein in the brain and heart of mice. ResultCompared with the sham operation group， the model group showed increased cerebral infarction area， neuroethological score， apoptosis rate， IBA-1-positive microglia proportion， and serum levels of NT-proBNP， CK-MB， and LDH （P<0.01）. Naoxintong capsules reduced the cerebral infarction area， neuroethological score， apoptosis rate， IBA-1-positive microglia proportion （P<0.01）， and serum NT-proBNP and CK-MB levels （P<0.05） in mice compared with the model group. Western blotting results showed that Naoxintong Capsules down-regulated the expression levels of TLR2 （P<0.05） in the brain and TLR2 （P<0.01） and TLR4 （P<0.05） in the heart. ConclusionCerebral ischemia can cause myocardial damage， reflecting the pathological process of cardiac injury after cerebral ischemia. Naoxintong capsules can mitigate brain and heart injuries after cerebral ischemia and achieve the simultaneous treatment of the brain and the heart， in which TLR2/TLR4 plays a role.

ObjectiveBased on the integrated strategy of "empirical prescriptions in ancient books-medical cases by prestigious doctors-computational analysis"， this study aims to explore and analyze the prescriptions and medical cases for treating tremors in traditional Chinese medicine （TCM）， predict their efficacy， and obtain the core prescriptions for treating tremors in TCM， providing references for clinical application and new drug development. MethodThe Chinese Medicine Prescription Database and the China National Knowledge Infrastructure （CNKI） were searched for relevant prescriptions and medical cases for treating tremors in TCM to establish a database of prescriptions for tremors. The Traditional Chinese Medicine Inheritance Computer System （V3.0） was used to analyze and explore the medication rules including drug frequency， properties， flavor， meridian tropism， and pharmacological effects， as well as core drugs and formula associations. A multi-target drug efficacy prediction platform based on network robustness was used to evaluate the predicted efficacy of the core prescriptions obtained. Based on the integration of ancient prescriptions， prestigious doctors' medical cases， and network analysis results， the priority level of the developed prescriptions was determined through comprehensive evaluation. ResultA total of 81 ancient prescriptions were screened， involving 246 drugs， and 171 prescriptions were screened from prestigious doctors' medical cases， involving 278 drugs. The frequently used TCM drugs were mostly warm in nature and sweet in flavor， mainly acting on the liver， spleen， and kidney meridians. In terms of efficacy， they were mainly effective in tonifying deficiency， soothing liver and extinguishing wind， activating blood and resolving blood stasis， clearing heat， and resolving exterior. Through association rules and K-means clustering， the core prescriptions were composed of high-frequency drugs such as Glycyrrhizae Radix et Rhizoma， Ginseng Radix et Rhizoma， Astragali Radix， Atractylodis Macrocephalae Rhizoma， Angelicae Sinensis Radix， Poria， Gastrodiae Rhizoma， and Uncariae Ramulus Cum Uncis. Drug combinations mainly focused on tonifying Qi and nourishing blood， with the additional functions of calming wind and dredging collaterals. Clustering analysis of core prescriptions from ancient prescriptions and prestigious doctors' medical cases， as well as multi-target drug efficacy prediction， showed that Combination 1 had the highest disturbance score on the disease network. Furthermore， comparative analysis revealed consistent results with both the analysis of ancient prescriptions and prestigious doctors' medical cases， indicating its optimal development potential based on theoretical inheritance and empirical practice. In comparison， Combinations 3， 2， and 4 were less utilized in contemporary clinical practice， with lower rankings in network disturbance scores， suggesting that their development value still warranted further exploration. ConclusionTCM clinical treatment of tremors emphasizes the regulation of the liver， spleen， and kidney. In line of syndrome differentiation， drugs potent in soothing liver， extinguishing wind， activating blood， and resolving blood stasis are added based on deficiency-tonifying drugs. The core prescriptions based on Glycyrrhizae Radix et Rhizoma， Angelicae Sinensis Radix， Paeoniae Radix Alba， Astragali Radix， Poria， and Atractylodis Macrocephalae Rhizoma （combination 1） have the highest potential development value. The integrated strategy "empirical prescriptions in ancient books-medical cases by prestigious doctors-computational analysis" can be used for the screening of candidate prescriptions for new TCM drugs.

ObjectiveTo explore the mechanism of Naoxintong capsules' intervention in cerebral ischemia-reperfusion by building a mouse cerebral ischemia-reperfusion model based on short-chain fatty acids. MethodC57BL/6J male mice were randomly divided into the sham group， model group， Naoxintong group （158.9 mg∙kg^-1）， and Ginaton group （12.1 mg∙kg^-1） according to the random number table method. The model of cerebral ischemia-reperfusion （MCAO/R） was prepared via the filament occlusion method. The effect of Naoxintong capsules on brain injury in MCAO/R mice was evaluated by the neuroethological score， cerebral infarction area determination， Nissl staining， and immunofluorescence staining. Hematoxylin-eosin （HE） staining and Western blot were employed to evaluate the effect of Naoxintong capsules on the intestinal barrier in MCAO/R mice. The content of short-chain fatty acids in mouse feces was detected by LC-MS/MS. ResultCompared to the sham group， the model group exhibited significant increases in the cerebral infarction area， neuroethological score， and cell apoptosis rate （P<0.01）， with a notable decrease in the number of Nissl bodies （P<0.01）. The protein expression levels of Claudin-1 and Occludin were significantly reduced （P<0.05）. Compared with the model group， the intervention of Naoxintong capsules significantly decreased the cerebral infarction area （P<0.05） and improved the neuroethological score （P<0.01） and cell apoptosis rate （P<0.01）， with the number of Nissl bodies （P<0.01） and expression levels of Claudin-1 and Occludin proteins （P<0.01） increased. LC-MS/MS results showed that compared to the sham group， the model group featured a significantly reduced content of acetic acid， propionic acid， and butyric acid in feces （P<0.01）， while valeric acid， isovaleric acid， and isobutyric acid levels were increased （P<0.01）. The intervention of Naoxintong capsules notably lowered the content of valeric acid， isovaleric acid， and isobutyric acid （P<0.01）. ConclusionNaoxintong capsules can improve brain and intestinal barrier damage and play a protective role in cerebral ischemia-reperfusion by regulating the content of short-chain fatty acids.

OBJECTIVETo study the accuracy of pulse contour cardiac output (PCCO) during blood volume change.

METHODSHemorrhagic shock model was made in twenty dogs followed by volume resuscitation. Two PiCCO catheters were placed into each model to monitor the cardiac output (CO). One of catheters was used to calibrate CO by transpulmonary thermodilution technique (COTP) (calibration group), and the other one was used to calibrate PCCO (none-calibration group). In the hemorrhage phase, calibration was carried out each time when the blood volume dropped by 5 percents in the calibration group until the hemorrhage volume reached to 40 percent of the basic blood volume. Continuous monitor was done in the none-calibration group.Volume resuscitation phase started after re-calibration in the two groups. Calibration was carried out each time when the blood equivalent rose by 5 percents in calibration group until the percentage of blood equivalent volume returned back to 100. Continuous monitor was done in none-calibration group. COTP, PCCO, mean arterial pressure (MAP), systemic circulation resistance (SVR), global enddiastolic volume (GEDV) were recorded respectively in each time point.

RESULTS(1) At the baseline, COTP in calibration group showed no statistic difference compared with PCCO in none-calibration group (P >0.05). (2) In the hemorrhage phase, COTP and GEDV in calibration group decreased gradually, and reached to the minimum value (1.06 ± 0.57) L/min, (238 ± 93) ml respectively at TH8. SVR in calibration group increased gradually, and reached to the maximum value (5 074 ± 2 342) dyn · s · cm⁻⁵ at TH6. However, PCCO and SVR in none-calibration group decreased in a fluctuating manner, and reached to the minimum value (2.42 ± 1.37) L/min, (2 285 ± 1 033) dyn · s · cm⁻⁵ respectively at TH8. COTP in the calibration group showed a significant statistic difference compared with PCCO in the none-calibration group at each time point (At TH1-8, t values were respectively -5.218, -5.495, -4.639, -6.588, -6.029, -5.510, -5.763 and -5.755, all P < 0.01). From TH1 to TH8, the difference in percentage increased gradually. There were statistic differences in SVR at each time point between the two groups (At TH1 and TH4, t values were respectively 2.866 and 2.429, both P < 0.05, at TH2 - TH3 and TH5 - TH8, t values were respectively 3.073, 3.590, 6.847, 8.425, 6.910 and 8.799, all P < 0.01). There was no statistic difference in MAP between the two groups (P > 0.05). (3) In the volume resuscitation phase, COTP and GEDV in the calibration group increased gradually. GEDV reached to the maximum value ((394±133) ml) at TR7, and COTP reached to the maximum value (3.15 ± 1.42) L/min at TR8. SVR in the calibration group decreased gradually, and reached to the minimum value (3 284 ± 1 271) dyn · s · cm⁻⁵ at TR8. However, PCCO and SVR in the none-calibration group increased in a fluctuating manner. SVR reached to the maximum value (8 589 ± 4 771) dyn · s · cm⁻⁵ at TR7, and PCCO reached to the maximum value (1.35 ± 0.70) L/min at TR8. COTP in the calibration group showed a significant statistic difference compared with PCCO in the none-calibration group at each time point (At TR1-8, t values were respectively 8.195, 8.703, 7.903, 8.266, 9.600, 8.340, 8.938, 8.332, all P < 0.01). From TR1 to TR8, the difference in percentage increased gradually. There were statistic differences in SVR at each time point between the two groups (At TR1, t value was -2.810, P < 0.05, at TR2-8, t values were respectively -6.026, -6.026, -5.375, -6.008, -5.406, -5.613 and -5.609, all P < 0.05). There was no statistic difference in MAP between the two groups (P > 0.05).

CONCLUSIONPCCO could not reflect the real CO in case of rapid blood volume change, which resulting in the misjudgment of patient's condition. In clinical practice, more frequent calibrations should be done to maintain the accuracy of PCCO in rapid blood volume change cases.
