ObjectiveTo analyze the differences in color， odor and volatile components of Citri Reticulatae Pericarpium（CRP） before and after being stir-fried with Halloysitum Rubrum， and to explore the material basis of enhancing the effect of strengthening spleen after processing and the scientific connotation of decoction pieces processed with Halloysitum Rubrum as the auxiliary material. MethodsThe volatile components of the samples before and after processing were identified and relatively quantified by headspace gas chromatography-mass spectrometry（HS-GC-MS）， and the volatile components were analyzed by principal component analysis（PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA）. According to the principle of variable importance in the projection（VIP） value>1.5， volatile differential components before and after processing were screened. And combined with intelligent sensory technologies such as colorimeter and electronic nose， the chroma and odor information of CRP before and after being stir-fried with Halloysitum Rubrum were identified. Pearson correlation analysis was used to explore the correlation between volatile differential components and chroma values. ResultsA total of 112 volatile components were identified from CRP and CRP stir-fried with Halloysitum Rubrum， of which 84 were from CRP and 97 were from CRP stir-fried with Halloysitum Rubrum. And 7 differential components were selected， including α-pinene， β-myrcene， linalool， sabinene， ocimene isomer mixture， A-ocimene， and δ-elemene. After being processed with Halloysitum Rubrum， the brightness value（L^*）， yellow-blue value（b^*） and total chromatic value（E^*_ab） of CRP were decreased（P<0.01）， and red-green value（a^*） was increased（P<0.01）， the response values of S4， S5， S10 and S13 sensors were significantly increased（P<0.05）， and the response values of S3 and S8 sensors were significantly decreased（P<0.05）. Correlation analysis showed that α-pinene and β-myrcene were negatively correlated with L^* and E^*_ab， but positively correlated with a^*. Sabinene was positively correlated with L^* and E^*_ab. Linalool was positively correlated with L^* and E^*_ab， and negatively correlated with a^*. The ocimene isomer mixture was positively correlated with the L^*. ConclusionAfter being processed with Halloysitum Rubrum， the appearance color， odor and volatile components of CRP change significantly， and α-pinene， β-myrcene， sabinene， linalool and A-ocimene are the characteristic volatile components before and after processing， which can provide references for the quality evaluation and clinical application of CRP and its processed products.

Objective:To investigate the correlation between the timing of minimally invasive puncture drainage and the outcome of patients with hypertensive intracerebral hemorrhage (HICH) in the basal ganglia region.Methods:Patients with HICH in the basal ganglia region underwent minimally invasive puncture and drainage at Hanchuan People's Hospital from January 2019 to September 2023 were selected. According to the timing of surgery, the patients were divided into onset to surgery time ≤12-hour group and >12-hour group. According to the modified Rankin Scale score at 90 days after onset, they were divided into a good outcome group (0-2) and a poor outcome group (>2). Multivariate logistic regression analysis was used to evaluate the independent influencing factors of functional outcome. Results:A total of 150 patients were included, with 78 males (52.00%), aged 53.15±4.35 years (range, 40-75 years). Eighty-six patients (57.33%) underwent surgery within 12 hours after onset, while 64 (42.67%) underwent surgery after 12 hours; 97 patients (64.67%) had good outcome, while 53 (35.33%) had poor outcome. Univariate analysis showed that compared with the onset to surgery time ≤12-hour group, the onset to surgery time >12-hour group had a longer time from onset to admission, a larger postoperative hematoma volume, longer hospitalization time, lower postoperative hematoma clearance rate, and a higher proportion of patients with poor outcome and deaths within 90 days (all P<0.05). Compared with the good outcome group, the poor outcome group had a longer time from onset to admission, higher baseline National Institutes of Health Stroke Scale (NIHSS) scores, larger baseline and postoperative hematoma volumes, and a higher proportion of patients with onset to surgery time >12 hours. However, the postoperative hematoma clearance rate, baseline Glasgow Coma Scale (GCS) score, and the proportion of patients with baseline GCS score >8 was lower in the poor outcome group (all P<0.05). Multivariate logistic regression analysis showed that the higher baseline NIHSS score (odds ratio [ OR] 1.847, 95% confidence interval [ CI] 1.362-2.503; P=0.001) and the time from onset to surgery >12 hours (compared with ≤12 hours: OR 1.347, 95% CI 1.058-1.715; P=0.016) were the independent risk factors for poor outcome, while higher baseline GCS scores ( OR 0.723, 95% CI 0.558-0.937; P=0.006) and higher postoperative hematoma clearance rates ( OR 0.615, 95% CI 0.462-0.819; P=0.004) were the independent protective factors for good outcome. Conclusion:In patients with HICH in basal ganglia, it is ideal to perform minimally invasive puncture and drainage within 12 h after onset, and the postoperative recovery is relatively better.

Objective:To explore the mechanism of exacerbating chronic graft versus host disease (GVHD) in mice with inflammatory status and enhancing immune injury in mice with PD-1.Method:Bone marrow and spleen cells of DBA/2 mice were injected into BALB/C mice pretreated with chemotherapy regimen (Flu+Bu) for constructing a chronic GVHD model. The animals were assigned into two groups of zymosan (100M SPL+10M BM+Zymosan) and control (100M SPL+10M BM+ PBS). After transplantation, two groups of mice were observed for weight changes, survival status and chronic GVHD manifestations. Target organ tissues were harvested for pathological scoring. Flow cytometry was employed for detecting cell subpopulations and surface co-stimulatory molecules in target organs. PD-1 monoclonal antibody was injected into inflammatory murine model. Mice were observed and target organ cells were harvested for subsets and co-stimulatory factors.Result:In in vivo experiments, zymosan group showed more significant changes of chronic GVHD with higher mortality rate, faster weight loss and more severe symptoms of GVHD. At Week 2 post-transplantation, hematoxylin-eosin stain of target organ tissue was performed for pathology examination. Zymosan group showed more lymphocyte infiltration, more severe inflammation and more significant tissue injury with higher GVHD pathological score. The proportion of M2 in liver/lung of zymosan group was significantly lower than that of control group ( P<0.05) and no significant difference existed in the proportion of M1. In in vivo experiments, M1 ratio of splenic cell spiked markedly in zymosan group as compared to control group while M2 ratio declined greatly. The secretions of IL-4 and IL-10 dropped significantly while co-stimulatory molecules CD80 and CD86 rose obviously. Conclusion:The worsening graft-versus-host disease in inflammatory mice with anti-PD1 treatment is associated with a decline of Treg proportion.

【Objective】 To analyze the basic characteristics of whole blood donors from blood stations before and after the outbreak of COVID-19. 【Methods】 After excluding invalid data, data related to the basic characteristics of whole blood donors collected from 26 blood stations in China during 2018 to 2021 were statistically analyzed, including the trend of total whole blood donors, the number of repeated blood donors, the frequency of blood donation, the average age of donors and the recruitment of first-time blood donors. 【Results】 Affected by the epidemic, 8 out of 14 indicators were with large variations, accounting for 57%. The overall growth rate of total whole blood donors during the epidemic was higher than before the epidemic (P<0.05).The number of repeated blood donors has shown an increased trend, with a higher number during the epidemic than before (P<0.05). The frequency of blood donation was lower during the epidemic than before(P<0.05).Average ages of blood donors and female blood donors fluctuated widely during the epidemic, both higher than those before the epidemic(P<0.05).The donation rate of first-time blood donors <25 years old and ≥25 years old varied widely and irregularly during the epidemic (both P<0.05). The percentage of first-time blood donors fluctuated irregularly during the epidemic, with overall percentage lower than that before the epidemic(P<0.05). 【Conclusion】 Whole blood donors from 26 blood stations increased after the outbreak of COVID-19, and some indicators in certain areas showed significant fluctuations during the epidemic.

Objective To investigate the incidence rate of pulmonary infection after laparoscopic surgery and related risk factors in patients with hepatocellular carcinoma (HCC) comorbid with liver cirrhosis and portal hypertension (PHT). Methods A retrospective analysis was performed for the clinical data of 105 HCC patients with liver cirrhosis and PHT who underwent laparoscopic surgery in Beijing Ditan Hospital, Capital Medical University, from January 2017 to February 2022. A total of 30 factors that might cause pulmonary infection were recorded, including general information, disease factors, surgical factors, and postoperative factors. Postoperative recovery was observed and the occurrence of pulmonary infection was recorded. The chi-square test or the Fisher's exact test was used for comparison of categorical data between two groups, and the multivariate logistic regression analysis was used to investigate the independent risk factors for pulmonary infection. Results Among the 105 patients, 66 underwent laparoscopic devascularization combined with hepatectomy and 39 underwent laparoscopic devascularization combined with radiofrequency ablation (RFA). The surgery was successful for all patients, with no case of conversion to laparotomy or unscheduled reoperation. No death was observed within 30 days after surgery and during hospitalization, with a median length of hospital stay of 20 days (range 14-25 days). The incidence rate of pulmonary infection was 25.71% (27/105). Smoking (odds ratio [ OR ]=3.362, 95% confidence interval [ CI ]: 1.282-8.817, P =0.014), MELD score ( OR =3.801, 95% CI : 1.007-14.351, P =0.049), tumor location ( OR =1.937, 95% CI : 1.169-3.211, P =0.010), surgical procedure ( OR =0.006, 95% CI : 0.001-0.064, P =0.000), intraoperative infusion volume ( OR =4.871, 95% CI : 1.211-19.597, P =0.026), and postoperative pleural effusion ( OR =9.790, 95% CI : 1.826-52.480, P =0.008) were independent risk factors for pulmonary infection. Conclusion There is a relatively high risk of pulmonary infection in HCC patients with liver cirrhosis and PHT undergoing laparoscopic surgery. Postoperative pleural effusion is the high risk factor for pulmonary infection, and devascularization combined with RFA can significantly reduce the risk of pulmonary infection. It is recommended to strengthen preoperative rehabilitation, perioperative liver function maintenance, intraoperative damage control, and goal-oriented fluid therapy and reduce postoperative fluid accumulation in the third space, so as to reduce the incidence rate of pulmonary infection.

In the context of non-alcoholic fatty liver disease (NAFLD), characterized by dysregulated lipid metabolism in hepatocytes, the quest for safe and effective therapeutics targeting lipid metabolism has gained paramount importance. Sanhuang Xiexin Tang (SXT) and Baihu Tang (BHT) have emerged as prominent candidates for treating metabolic disorders. SXT combined with BHT plus Cangzhu (SBC) has been used clinically for Weihuochisheng obese patients. This retrospective analysis focused on assessing the anti-obesity effects of SBC in Weihuochisheng obese patients. We observed significant reductions in body weight and hepatic lipid content among obese patients following SBC treatment. To gain further insights, we investigated the effects and underlying mechanisms of SBC in HFD-fed mice. The results demonstrated that SBC treatment mitigated body weight gain and hepatic lipid accumulation in HFD-fed mice. Pharmacological network analysis suggested that SBC may affect lipid metabolism, mitochondria, inflammation, and apoptosis-a hypothesis supported by the hepatic transcriptomic analysis in HFD-fed mice treated with SBC. Notably, SBC treatment was associated with enhanced hepatic mitochondrial biogenesis and the inhibition of the c-Jun N-terminal kinase (JNK)/nuclear factor-kappa B (NF-κB) and extracellular signal-regulated kinase (ERK)/NF-κB pathways. In conclusion, SBC treatment alleviates NAFLD in both obese patients and mouse models by improving lipid metabolism, potentially through enhancing mitochondrial biogenesis. These effects, in turn, ameliorate inflammation in hepatocytes.

This article reported the management and outcome of a pregnant woman diagnosed with massive subchorionic thrombohematoma at the umbilical cord insertion. The patient was found to have a large placental hematoma below the insertion site of the umbilical cord at 28 weeks of gestation by ultrasound and MRI. Fetal growth and the condition of the placenta were closely monitored thereafter. The patient was delivered with good maternal and infant outcomes through emergency cesarean section at 33 +5 weeks of gestation due to a significantly enlarged hematoma with abnormal umbilical blood flow.

Objective:To evaluate the efficacy of Baixiao moxibustion combined with acupuncture in the treatment of patients with dysmenorrhea of cold coagulation and blood stasis.Methods:A total of 90 patients with dysmenorrhea of cold coagulation and blood stasis who were treated in Huangpu Branch of Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine and met the inclusion criteria were enrolled between January 2019 and January 2020, and they were divided into observation group (47 patients) and control group (43 patients) according to the random number table method. The control group was treated by acupuncture, while the observation group combined Baixiao moxibustion with acpuncture treatment. Both groups were treated for 3 menstrual cycles. Before and after treatment, TCM syndromes were scored, Visual Analogue Scale (VAS) was used to evaluate pain intensity, and uterine hemodynamics were detected by ultrasonic diagnostic apparatus. The pulsatility index (PI), resistance index (RI) and ratio of peak systole/peak diastole (S/D) were recorded and the clinical efficacy was assessed.Results:The total effective rate was 97.87% (46/47) in observation group and that in control group was 81.40% (35/43), and the difference between two groups were significant ( χ2=6.77, P=0.009). After treatment, the scores of lower abdominal pain, dark blood clots, intolerance of cold and cold limbs and nausea and vomiting as well as VAS scores in the observation group were significantly lower than those in the control group ( t=3.61, 5.60, 6.22, 8.02, 10.36, all Ps<0.01). After treatment, the RI (1.45±0.55 vs. 1.86±0.53, t=3.59), PI (0.61±0.14 vs. 0.77±0.13, t=5.60) and S/D (5.28±1.18 vs. 7.23±1.22, t=7.71) in observation group were significantly lower than those in control group ( P<0.01). Conclusion:Baixiao moxibustion combined with acupuncture can relieve the pain symptoms, improve the TCM syndromes and promote the uterine blood circulation.
