Objective:To screen out high risk factors of cervical intraepithelial neoplasia (CIN) of grade Ⅱ or worse (CIN Ⅱ +) by analyzing related factors for CIN Ⅱ + detection in grade 1 abnormal colposcopic finding (G1) of cervix and provide reference for individual management of colposcopic performance. Methods:A retrospective study was performed on patients who were reffered to colposcopy for abnormal results of cervical cancer screening and only had G1 colposcopic findings of cervix at the First Affiliated Hospital of Nanjing Medical University, from April 2017 to January 2021. The factors influencing the detection of CIN Ⅱ + were analyzed by univariate and multivariate analysis. Results:(1) A total of 403 patients were included in this study whose median age was 38 years old (range: 22-67 years old), and utimately 108 had high-grade squamous intraepithelial lesion, 1 had adenocarcinoma in situ and 1 had adenocarcinoma. The overall detection rate of CIN Ⅱ + was 27.3% (110/403). (2) Univariate analysis showed that the detection rate of CIN Ⅱ +, in patients ≥50 years old was higher than that in patients <50 years old (38.3% vs 25.4%; χ2=4.328, P=0.037), and in HPV 16 positive cases was higher than that in non-HPV 16 positive cases (41.8% vs 21.8%; χ2=16.080, P<0.01); as the cytological severity ( χ2=6.775, P=0.009) and the number of involving quadrants ( χ2=31.117, P<0.01) increased, the risk of CIN Ⅱ + detection increased; but the types of colpolscopic signs were not related to detection of CIN Ⅱ +( χ2=0.323, P=0.851). Multivariable analysis showed that the age of ≥50 years old ( OR=2.504, 95% CI: 1.299-4.830, P=0.006), HPV 16 positive type ( OR=3.353, 95% CI: 2.004-5.608, P<0.01) and the increase of involving quadrants ( OR=1.899, 95% CI: 1.518-2.376, P<0.01) were independent risk factors. (3) The detection rate of CIN Ⅱ + was highest in the women with HPV 16 positive type and four quadrants of G1 (73.7%), while lowest in the women with non-HPV 16 positive type and one quadrant of G1 (10.4%). Conclusions:The age of ≥50 years old, HPV 16 positive type and the increase of involving quadrants are independent risk factors of detecting CIN Ⅱ + in G1 colposcopic findings. So the key point of the individual management of G1 groups with different risk stratification is to adequately biopsy in high-risk group to avoid miss diagnosis of CIN Ⅱ +.

Objective We tried to investigate the difference of respiratory symptoms,quality of life,blood routine examination and bone metabolism in patients with newly diagnosed chronic obstructive pulmonary disease with and without hypertension.Methods A total of 92 newly diagnosed patients with chronic obstructive pulmonary disease and hypertension treated in our hospital from January 2019 to April 2022 were selected as the observation group,and 92 newly diagnosed patients with COPD without hypertension were selected as the control group.The modified British Medical Research Council Respiratory Questionnaire(mMRC),Chronic Obstructive Pulmonary Disease Self Assessment Test Questionnaire(CAT),Global Initiative for Chronic Obstructive Pulmonary Disease(GOLD),SF-36 scale scores,blood routine examination and bone metabolism indexes were different.Results The rate of mMRC grade≥2 and CAT score of the observation group were significantly higher than those of the control group(P＜0.05),while the SF-36 score was significantly lower than that of the control group(P＜0.05).The GOLD grading of the observation group was significantly higher than that of the control group(P＜0.05).The forced vital capacity(FVC)and the first second expiratory volume(FEV1)in the observation group were significantly lower than those in the control group(P＜0.05).There was no significant difference between the observation group and the control group in white blood cell count(WBC),neutrophil count(NEUT)and lymphocyte count(LYM)etc(P＞0.05).The bone mineral density of the femoral neck and blood calcium in the observation group were signifi-cantly lower than those in the control group(P＜0.05),while the parathyroid hormone(PTH)and osteocalcin(BGP)were significantly higher than those in the control group(P＜0.05).The levels of C-reactive protein(CRP),procalcitonin(PCT),interleukin-6(IL-6),IL-4,and IL-10 in the observation group were significantly higher than those in the control group(P＜0.05).The hypertension grade in the observation group was positively correlated with mMRC grade,CAT score and GOLD grade(rs=0.455,0.302 and 0.501,P＜0.05),but negatively correlated with FVC and FEV1(rs=-0.311 and-0.334,P＜0.05).Conclusion The newly diagnosed patients with chronic obstructive pulmonary disease and hypertension have severe respiratory symptoms,poor quality of life,and an increased risk of osteoporosis,and the patient's blood pressure is related to the degree of respiratory symptoms.

Objective:To explore the correlation between oxidative stress markers malondialdehyde(MDA), superoxide dismutase(SOD), magnetic resonance burden and vascular cognitive impairment in patients with ischemic cerebrovascular disease (CSVD).Methods:Totally 300 patients with ischemic cerebral small vessel diseases who were admitted to the Department of Neurology, North China University of Science and Technology Affiliated Hospital were selected as the research subjects, and 60 healthy outpatients in the same period were selected as the control group.According to the results of mini mental state examination(MMSE), patients with ischemic cerebral small vessel diseases were divided into cognitive normal group (106 cases) and cognitive impairment group (194 cases). The cognitive impairment group was further divided into mild cognitive impairment group (101 cases), moderate cognitive impairment group (58 cases ) and severe cognitive impairment group (35 cases) according to Montreal cognitive assessment (MoCA). MDA and SOD were determined by double antibody sandwich method and the results were compared and analyzed.Results:(1) Compared with the control group(MDA: (8.40±1.81)μmol/L, SOD: (112.73±83.48)U/ml), the level of MDA increased while the level of SOD decreased significantly in normal group(MDA: (8.46±2.05)μmol/L, SOD: (108.90±88.72)U/ml) and cognitive impairment group(MDA: (12.19±7.02)μmol/L, SOD: (62.64±20.34)U/ml). Compared with the cognitive normal group, the level of SOD decreased significantly and MDA increased significantly in cognitive impairment group, the differences were statistically significant (all P<0.05). Compared with the normal cognitive group (1.18±1.10), the cognitive impairment group (1.93±1.05) had a higher MRI burden score ( P<0.05). (2)Multivariate analysis showed that the decrease of plasma SOD level( β=-0.024, OR=0.977, 95% CI=0.961-0.992)and the increase of plasma MDA level( β=0.110, OR=1.117, 95% CI=1.005-1.241)and the MRI overall burden( β=0.453, OR=1.573, 95% CI=1.011-2.446)were independent protective factors of vascular cognitive impairment in patients with ischemic CSVD.(3) Compared with mild cognitive impairment group(MDA: (9.79±5.79)μmol/L, SOD: (81.64±58.09)U/ml, MRI overall burdern (1.69±0.99)), the level of SOD decreased significantly and the level of MDA and the MRI overall burden increased significantly in moderate cognitive impairment group and severe cognitive impairment group(MDA: (7.95±2.44)μmol/L, SOD: (76.13±46.00)U/ml, MRI overall burden: (1.78±0.86)), (MDA: (11.16±6.68)μmol/L, SOD: (63.49±20.04)U/ml, MRI overall burden: (2.89±1.02). Compared with the moderate cognitive impairment group, the level of SOD decreased significantly and the level of MDA and the MRI overall burden increased significantly in the severe cognitive impairment group (all P<0.05). Conclusion:Increased plasma MDA level, MRI burden score and decreased SOD level in patients with CSVD are all risk factors for the occurrence of cognitive impairment.It is suggested that oxidative stress injury and cerebral small vessel lesions may be involved in the occurrence and development of cognitive impairment of CSVD from multiple aspects.

Objective:To investigate the value and feasibility of early goal directed sedation (EGDS) in patients with acute brain injury.Methods:A total of 110 patients with acute brain injury who were admitted to intensive care unit (ICU) of the Third Medical Center of the Chinese People's Liberation Army General Hospital from January 2015 to March 2019 were included and randomly divided into EGDS group and standard sedation group (STD) using the random number table. Patients in the EGDS group were sedated by continuous intravenous infusion of dexmedetomidine (initial dose of 0.2 μg·kg -1·min -1) for 72 consecutive hours. Patients in the STD group received intravenous bolus of propofol as appropriate clinically. Richmond agitation-sedation score (RASS) and electroencephalogram bispectral index (BIS) were used to continuously monitor the level of sedation. All patients were given sufentanil for analgesia. Routine treatments such as dehydration and reduction of intracranial pressure with mannitol, hemostasis or antiplatelet therapy were given according to the patients' condition. Vital signs, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score, Glasgow coma scale (GCS) score, BIS value, artery blood gas analysis, duration of mechanical ventilation, analgesic dosage and adverse events were recorded in two groups before and 24, 48, and 72 hours after sedation. Results:① Among the 110 patients, patients who received the second surgery due to cerebral hemorrhage, had worsening of cerebral hernia, withdrew during the course of the study, or whose family members abandoned treatment were excluded from the study. Finally, 105 patients were enrolled in the study, including 56 patients in the EGDS group and 49 in the STD group. There was no significant difference in gender, age, types of brain injury, baseline APACHEⅡ or GCS score or rate of mechanical ventilation between the two groups. ② Compared with before sedation, heart rate (HR) significantly decreased till 72 hours after sedation in both groups, and the decrease in the EGDS groups was more obvious as compared with the STD group (bpm: 70.49±7.53 vs. 79.83±9.48, P < 0.05). Besides HR, significant improvement was found in the APACHEⅡ and GCS scores in the STD group at 72 hours of sedation as compared with before sedation, and no significant difference was found in other indicators. Compared with before sedation, arterial partial pressure of carbon dioxide (PaCO 2) was significantly increased from the 24th hour of sedation, mean artery pressure (MAP) was decreased significantly and GCS score, BIS value were increased significantly from the 48th hour of sedation, till 72 hours, which were all improved significantly as compared with the STD group [72-hour PaCO 2 (mmHg, 1 mmHg = 0.133 kPa): 40.30±5.98 vs. 31.57±8.20, 72-hour MAP (mmHg): 85.01±8.26 vs. 89.54±9.41, 72-hour GCS score: 8.62±3.34 vs. 7.89±2.74, 72-hour BIS: 60.87±24.79 vs. 56.68±33.43, all P < 0.05]. APACHEⅡ score was significantly lower only at the 72nd hour of sedation as compared with before sedation in the EGDS group, and no significant difference was found as compared with the STD group (17.10±7.05 vs. 18.90±3.32, P > 0.05). Oxygenation index (PaO 2/FiO 2) was significantly increased only at the 24th hour of sedation in the EGDS group as compared with the STD group (mmHg: 261.05±118.45 vs. 226.45±96.54, P < 0.05). ③ The duration of mechanical ventilation was significantly shorter in the EGDS group than that in the STD group (hours: 20.56±9.03 vs. 27.75±11.23, P < 0.05), and the total administered dose of sufentanil was significantly lower in the EGDS group than that in the STD group (μg: 79.16±26.76 vs. 102.46±35.48, P < 0.05). ④ Compared with the STD group, the incidence of bradycardia in the EGDS group was increased significantly [10.71% (6/56) vs. 6.12% (3/49), P < 0.05], while the incidence of tachycardia was decreased significantly [14.29% (8/56) vs. 38.78% (19/49), P < 0.05], but no significant difference was found in the incidence of hypotension [5.36% (3/56) vs. 4.08% (2/49), P > 0.05]. The incidence of unexpected extubation in the STD group was 4.08% (2/49), which did not occurre in the EGDS group. Conclusion:EGDS can improve the GCS score and BIS value of patients with acute brain injury, suggesting that the EGDS is safe and feasible, which can help improve neurological function in patients with acute brain injury.

Shengma Gegentang is one of the classic formulas in the Catalogue of Ancient Classic Prescriptions （Second Batch）. This study reviewed ancient and modern literature and used literature tracing and bibliometric methods to analyze the historical evolution， efficacy， indications， dosage decoctions， and modern clinical disease spectrum of Shengma Gegentang. The results indicated that the earliest record of Shengma Gegentang can be found in the Taiping Huimin Heji Jufang of the Song dynasty， but its origin can be traced back to the Shaoyao Siwu Jiejitang in the Beiji Qianjin Yaofang of the Tang dynasty. The composition dosage of Shengma Gegentang is 413 g of Cimicifugae Rhizoma， 619.5 g of Puerariae Lobatae Radix， 413 g of Paeoniae Radix Alba， and 413 g of Glycyrrhizae Radix et Rhizoma， which are ground into coarse powder. Each dose is 12.39 g， and the amount of water added is 300 mL. 100 mL of solution is decocted and taken at the right time. The four drugs in the formula play the role of relieving exterior syndrome， penetrating pathogenic factors， and detoxicating together. Its indications are widely involved in internal medicine， pediatrics， surgery， ophthalmology and otorhinolaryngology， obstetrics and gynecology， sexually transmitted diseases， and other diseases， such as measles， sores， acne， spots， surgical gangrene， red eyes， toothache， chancre， and fetal poison. The epidemic diseases treated by Shengma Gegentang are complicated， including rash， pox， macula， numbness， summer diarrhea， dysentery， sha disease， febrile symptoms， spring warmth， winter warmth， and cold pestilence. At the same time， it is a plague prevention formula. Although Shengma Gegentang has a wide range of indications， it cannot be separated from the pathogenic mechanism of evil Qi blocking the muscle surface and heat in the lungs and stomach. The modern clinical disease spectrum of Shengma Gegentang involves the ophthalmology and otorhinolaryngology system， nervous system， pediatric-related diseases and syndromes， skin system， hepatobiliary system， and digestive system. It plays a key role in the treatment of epidemic diseases such as measles， chronic hepatitis B， dysentery， and tetanus.
