Objective To establish a rapid determination of sodium valprate in plasma by capillary zone electrophoresis.Method Plasma was acidized by 1 mol/L HCl, VPA was extracted into organic phase (n-Hexane), then re-extracted into aqueous phase (0.05 mmol/L NaOH solution including 15% Ethanol). Capillary clone was 75 ?m(id)?37 cm. Electrolyte consisted of 15 mmol/L sodium salicylate, 0.5 mmol/L CTAB and 15% Ethanol (pH 5.7).Separating voltage was 20 kV, detection wave was 214 nm, temperature was 20℃,injection time was 5 s by press in negative.Result The linear ranger of concentration for standard drug was between 25~200 ?g/ml (r=0.999),the limit of detection was 0.35 ?g/ml, the average recovery of VPA was 87.4%,the average inter-day and intar-day CV were less than 4% and 6%. Conclusion This method is simple, rapid, reliable and correct, for determination of VPA in plasma.

Objective To estimate the anatomic variation of the right inferior phrenic artery(RIPA)with multi-detector tomography(MDCT)scans.Methods 45 patients with hepatocellular carcinoma(HCC)and 46 healthy subjects were examined by contrast-enhanced CT scan(CTA)at 16-section CT scanner.Then the images were reconstructed with MPR,VR and MIP.Results RIPA were detected by CTA in all cases(sensitivity was 100%).The origin of RIPAs directly from the aorta in 42%,celiac trunk in 37%,right renal artery in 15%,left gastric artery in 3% and proper hepatic artery in 2%.For the reconstructive images quality,MPR and MIP were better than VR,but in showing the origin of RIPAs,MPR and VR were better than MIP.In compared with normal group,the diameters of RIPAs in tumor group were larger.Conclusion MDCT estimates well for the anatomy of RIPAs,which is significant for planning and embolization of extrahepatic RIPA supply in HCC.

Aim To observe the protective effects of SITS and DIDS,two kinds of chloride channel blockers,on hippocampal neuronal damage induced by NO in culture.Methods The cultures were divided into three groups:control group,NO treatment group,NO treatment plus chloride channel blocker group. The cultures were detected with the methods of morphological stain (Hoechst 33258),and the apoptotic neurons and neuronal viabilities were observed through MTT quantitative analysis. The activated caspase-3 was analyzed with western blot.Results There were significant protective effects of SITS and DIDS on neuronal damage with dose-dependence.Conclusions Chloride channel blockers have some protective effects against neuronal injury induced by NO.

Two patients with neonatal diabetes tested as V59A and V59M mutations were chosen for the study. Clinical data were analyzed retrospectively. The results showed that the patient with V59A mutation was characteristic of spasm and hyperglycemia at the age of three month, and treated with insulin for a long time as unresponsive to the glibenclamide at the beginning. Myasthenia and delay of development were observed during the follow-up. At the age of two years, glibenclamide was tried for the second time with a high dose and fairly-controlled glucose level. The patient with V59M mutation was diagnosed with diarrhea, hyperglycemia, and ketosis at the age of two month, and was responsive to glibenclamide at a relatively low dose with well-controlled glucose level. These results suggest that KCNJ11 V59M mutation would show some milder clinical manifestations and better glibenclamide efficacy as compared with V59A mutation.

Iridoid glycosides (mainly geniposide) and crocetin derivatives (crocins) are the two major active constituents in Gardenia jasminoides Ellis. In the present study, geniposide, crocins, crocin-1 and crocetin were separated from gardenia chromatographically. Then, mice were orally administrated with geniposide (400 mg/kg b.w.), crocins (400 mg/kg b.w.), crocin-1 (400 mg/kg b.w.) and crocetin (140 mg/kg b.w.) once daily for 7 days with CCl4. Hepatoprotective properties were evaluated by biochemical parameters: Administration of geniposide, crocins, crocin-1and crocetin significantly lowered serum alanine transaminase (ALT), aspartate transaminase (AST) and alkaline phosphatase (ALP) levels in CCl4-treated mice. The reduced glutathione (GSH) levels and antioxidant enzymes (SOD and CAT) activities were also increased by geniposide, crocins, crocin-1 and crocetin. Histopathological examination of livers showed that these components reduced deformability, irregular arrangement and rupture of hepatocyte in CCl4-treated mice. These biochemical results and liver histopathological assessment demonstrated that geniposide, crocetin derivatives and crocetin show comparative beneficial effects on CCl4-induced liver damage via induction of antioxidant defense. Therefore, contents of geniposide and crocetin derivatives should be both considered for hepatoprotective efficacy of Gardenia jasminoides Ellis.

Objective:To investigate sedation level for postoperative patients with mechanical ventilation in ICU, and to explore the related factors and patient outcomes with different sedation level.Methods:Totally 163 postoperative ICU patients from 11th June to 30th October 2018 were prospectively analyzed. Medical information and all the RASS (Richmond Agitation Sedation Scale) scores was recorded by nurses.Results:The 163 enrolled patients received 11 261.62 hours mechanical ventilation therapy, and 2 815 RASS scores were assessed and recorded by nurses. Among these scores, 80.3% (2 261/2 815) were at light sedation level, while 17.4% (490/2 815) and 2.3% (64/2 815) were at excessive or insufficient sedation level, respectively. All patients were divided into satisfactory sedation group and unsatisfactory sedation group according to the recommendations of guidelines, and used both univariate analysis and multivariate analysis. Compared to males, female patients tend to be in a satisfactory sedation level ( OR value was 0.39, P<0.05); use of midazolam may increase the risk of unsatisfactory sedation level ( OR value was 5.60, P<0.05); the longer sedation assessment interval ( OR value was 1.70, P<0.05), the more likely the patient′s sedation level is unsatisfactory ( OR value was 1.70, P<0.05) . Patients in sedation unsatisfactory group have higher rate of tracheostomy ( χ 2 value was 9.70, P<0.01), longer ICU stay ( U value was -2.33, P<0.05) and more medical expense ( t value was -4.26, P<0.01). Conclusion:The current sedation management in our ICU is satisfactory, but there is still a small part of patients in a state of insufficient sedation or excessive sedation. Sedation level is closely related to sedatives, RASS assessments interval performed by the nurses. This study provides a reference and basis for clinical sedation management and the sedation assessment strategies in the ICU.

Objective:To investigate the epidemiological data of maternal sepsis in intensive care unit (ICU), analyze the common causes, outcomes of maternal sepsis, and the risk factors of multi-drug resistant (MDR) bacteria.Methods:A retrospective cohort study. Maternal sepsis cases admitted to ICUs of Peking University Third Hospital, Beijing Chao-Yang Hospital Affiliated to Capital Medical University, and Beijing Friendship Hospital Affiliated to Capital Medical University from January 2008 to September 2022 were enrolled. The following data were recorded: demographic characteristics, sequential organ failure assessment (SOFA) during infection, infection time, infection sites, invasive intervention measures before infection, microbial culture results, blood routine test during infection, body temperature, and clinical outcomes caused by infection. According to the time of sepsis occurrence, the patients were divided into pre-ICU sepsis group and ICU sepsis group, and the causes of sepsis in the two groups were analyzed. According to whether MDR occurred, the patients were divided into MDR group and non-MDR group, and clinical outcomes were analyzed. Multivariate Logistic regression was used to analyze the risk factors of MDR bacteria infection in obstetrics with sepsis.Results:160 patients were enrolled, among which 104 cases of sepsis happened before ICU and 56 cases of sepsis happened during ICU, 53 cases were with MDR bacteria and 107 cases were without MDR bacteria. The median age of the patients was 30.5 (28.0, 34.0) years old, the median temperature was 38.8 (38.2, 39.5) ℃, and the median white blood cell count (WBC) was 17.2 (13.2, 21.3)×10 9/L, the median SOFA score was 5.0 (3.0, 8.0), and 130 cases (81.2%) were referred from other hospitals. The main infection sites were uterine cavity in 64 cases (40.0%), lung in 48 cases (30.0%), abdominal and pelvic cavity in 30 cases (18.8%), urinary system in 27 cases (16.9%). Sepsis led to hysterectomy in 6 cases (3.8%), stillbirth in 8 cases (5.0%), and neonatal death in 2 cases (1.3%). The main surgical intervention measures were cesarean section (44 cases, accounting for 27.5%), followed by exploratory laparotomy (19 cases, 11.9%). The median length of ICU stay was 5.0 (3.0, 10.0) days, and the median hospital length was 14.0 (10.0, 20.8) days. Intrauterine infection was the primary cause of sepsis happened during ICU, accounting for 50.0% (28/56), of which postpartum hemorrhage accounted for 85.7% (24/28). The proportion of diabetes [28.3% (15/53) vs. 14.0% (15/107)], intrauterine operation [41.5% (22/53) vs. 23.4% (25/107)], intrauterine infection [50.9% (27/53) vs. 34.6% (37/107)] and bacteremia [18.9% (10/53) vs. 2.8% (3/107)] in the MDR group were significantly higher than those in the non-MDR group (all P < 0.05). Multivariate Logistic regression analysis showed that diabetes [odds ratio ( OR) = 2.348, 95% confidence interval (95% CI) was 1.006-5.480, P = 0.048] and intrauterine operation ( OR = 2.541, 95% CI was 1.137-5.678, P = 0.023) were independent risk factors for MDR bacterial infection in obstetrics with sepsis. Conclusions:Intrauterine infection is the common cause of maternal sepsis in ICU, and postpartum hemorrhage is the common cause of secondary intrauterine infection in ICU. MDR bacteria can lead to serious clinical outcomes. Diabetes and intrauterine operation are independent risk factors for MDR bacteria' infection.

Objective:To compare the clinical characteristics of critically ill pregnant women admitted to the intensive care unit (ICU) with different admission methods, in order to make more effective and rational use of ICU resources.Methods:A retrospective study was conducted. The clinical data of critically ill pregnant women admitted to ICU of Peking University Third Hospital from January 2006 to July 2019 were analyzed. According to the admission mode to ICU, the pregnant women were divided into emergency admission group (transferred to ICU on the same day or the next day due to critical illness) and planned admission group (transferred to ICU 2 days after admitting in obstetric ward). The clinical characteristics of ICU critical pregnant women, such as the incidence, causes of admission, severity of the disease, main treatment measures, mortality, and medical expenses were collected, and a comparative analysis between the two groups was performed.Results:During the nearly 14 years, a total of 576 critical pregnant women in ICU were enrolled, accounting for 0.8% (576/71 790) of the total number of obstetric inpatients and 4.6% (576/12 412) of the total number of ICU inpatients. Seven maternal deaths accounted for 1.2% of all critically pregnant women transferred to ICU, and the overall mortality of pregnant women was 10/100 thousand. Of the 576 critically pregnant women, there were 327 patients (56.8%) in the emergency admission group and 249 patients (43.2%) in the planned admission group. Compared with the planned admission group, the proportion of elective cesarean section in the emergency admission group was significantly lower (17.7% vs. 94.0%, P < 0.01), and the proportion of emergency cesarean section was significantly higher (65.1% vs. 2.4%, P < 0.01), the acute physiology and chronic health evaluation (APACHE Ⅱ, APACHE Ⅲ) scores, simplified acute physiology score Ⅱ (SAPS Ⅱ) and Marshall score were significantly higher [APACHE Ⅱ score: 6.0 (4.0, 9.8) vs. 4.0 (3.0, 7.0), APACHE Ⅲ score: 14.0 (11.0, 20.3) vs. 12.0 (9.0, 16.0), SAPS Ⅱ score: 8 (0, 12) vs. 3 (0, 8), Marshall score: 2 (1, 4) vs. 1 (1, 3), all P < 0.01]. The length of ICU stay in the emergency admission group was significantly longer than that in the planned admission group [days: 2 (1, 5) vs. 2 (1, 3), P < 0.01], and the total length of hospital stay was significantly shorter [days: 9 (7, 13) vs. 13 (10, 18), P < 0.01]. Both in the emergency admission group and the planned admission group, obstetric factors were the main reason for admission, 60.9% (199/327) and 70.3% (175/249), respectively. The proportion of postpartum hemorrhage was the highest [35.2% (115/327) and 57.0% (142/249)], followed by preeclampsia/eclampsia [7.0% (23/327) and 7.6% (19/249)]. Only 7 of the 19 critically pregnant women with puerperal infection were planned admission. All 21 patients with acute fatty liver of pregnancy (AFLP) during pregnancy were emergency admission. Among the emergency and planned admission patients, 73 patients (22.3%) and 42 patients (16.9%) required mechanical ventilation (duration of mechanical ventilation > 24 hours), 99 patients (30.3%) and 35 patients (14.1%) needed vasoactive agents, 67 patients (20.5%) and 20 patients (8.0%) received hemodynamic monitoring, and 123 patients (37.6%) and 154 patients (61.8%) were given anticoagulation therapy, respectively. In terms of severity score of critical pregnant women, there were significant differences in APACHE Ⅱ, APACHE Ⅲ, SAPS Ⅱ and Marshall scores of pregnant women with different diseases. Among them, the APACHE Ⅲ, SAPS Ⅱ and Marshall scores of AFLP were the highest [21.0 (15.0, 32.5), 12.0 (6.0, 16.5) and 6.0 (3.5, 8.0), respectively]. The APACHE Ⅱ and APACHE Ⅲ scores of postpartum hemorrhage were the lowest [4.0 (3.0, 7.0), 12.0 (10.0, 16.0)]. The SAPS Ⅱ score of pneumonia was the lowest [2.0 (0, 14.0)]. The Marshall score for puerperal infection was the lowest [1.0 (0, 3.0)]. In terms of the total medical expenses, the cost in the emergency admission group was significantly lower than that in the planned admission group [10 thousand Yuan: 3.1 (2.0, 4.7) vs. 4.1 (2.9, 5.8), P < 0.05]. Conclusions:Compared with the critically ill pregnant women who planned to be admitted to ICU, the patients emergency admitted to ICU were more complicated and urgent, and the severity of the condition was scored higher. At present, the severity scoring system commonly used in ICU can only partly evaluate the severity of critically ill pregnant women, therefore, it is necessary to design the specific severity scoring system for critically ill pregnant women to effectively and rationally use the precious ICU resources.

Objective To investigate the correlation between somatosensory evoked potentials(SEP)of upper limbs,and sensory and motor functions in stroke patients in different stages. Methods From June,2021 to October,2023,177 stroke patients in Shijiazhuang People's Hospital were diveded into acute stage group(within 14 days,n=25),early recovery group(14 days to one month,n=110)and middle to late recovery group(one to six months,n=42)according to the duration of the disease.General information of the patients was recorded;SEP examination was performed,and N20 lantency and amplitude were recorded.Monofilament touch and two-point discrimination sensation of the patient's hands were tested using the monofila-ment and two-point discrimination tools,respectively;and motor function was assessed with Fugl-Meyer Assess-ment-Upper Extremities(FMA-UE).The correlation between SEP,and the sensory and motor scores in each group was analyzed. Results There was no significant difference in the monofilament tactile and two-point discrimination scores among the three groups(P>0.05).SEP was not correlated with sensory and motor functions in the acute stage group(P>0.05);in the early recovery group,N20 latency was negatively correlated with monofilament tactile sensation(r=-0.267,P=0.005)and positively correlated with two-point discrimination sensation(r=0.220,P=0.021),and N20 amplitude was positively correlated with monofilament tactile sensation(r=0.328,P<0.001)and FMA-UE score(r=0.418,P<0.001),and negatively correlated with two-point discrimination(r=-0.405,P<0.001);in the middle to late recovery group,the N20 latency was negatively correlated with FMA-UE score(r=-0.313,P=0.044),and N20 amplitude was positively correlated with monofilament tactile sensation(r=0.598,P<0.001)and FMA-UE score(r=0.393,P=0.010),and negatively correlated with two-point discrimination(r=-0.591,P<0.001).Multiple linear regression analyses showed that the score of monofilament tactile sensa-tion was negatively correlated with N20 latency(β=-0.510,P=0.046),and the FMA-UE score was positively correlated with N20 amplitude(β=0.313,P=0.026)in the middle to late recovery group;in the early recovery group,the two-point discriminative sensation score was negatively correlated with N20 amplitude(β=-0.270,P=0.039). Conclusion The correlation between SEP and sensory and motor functions becomes more significant with the prolonga-tion of disease.

Stress and illness connection is complex and involves multiple physiological systems. Panax ginsengs, reputed for their broad-spectrum "cure-all" effect, are widely prescribed to treat stress and related illnesses. However, the identity of ginseng's "cure-all" medicinal compounds that relieve stress remains unresolved. Here, we identify ginsentides as the principal bioactives that coordinate multiple systems to restore homeostasis in response to stress. Ginsentides are disulfide-rich, cell-penetrating and proteolytic-stable microproteins. Using affinity-enrichment mass spectrometry target identification together with in vitro, ex vivo and in vivo validations, we show that highly purified or synthetic ginsentides promote vasorelaxation by producing nitric oxide through endothelial cells via intracellular PI3K/Akt signaling pathway, alleviate α1-adrenergic receptor overactivity by reversing phenylephrine-induced constriction of aorta, decrease monocyte adhesion to endothelial cells via CD166/ESAM/CD40 and inhibit P2Y12 receptors to reduce platelet aggregation. Orally administered ginsentides were effective in animal models to reduce ADP-induced platelet aggregation, to prevent collagen and adrenaline-induced pulmonary thrombosis as well as anti-stress behavior of tail suspension and forced swimming tests in mice. Together, these results strongly suggest that ginsentides are the principal panacea compounds of ginsengs because of their ability to target multiple extra- and intra-cellular proteins to reverse stress-induced damages.
