Objective To compare the bispectral index score ( BIS) correlationbetween standard frontal sensor position and an alternative zygomatic position under general anesthesia with propofol combined with remifentanil during neurosurgery. Methods Twenty patients undergoing neurosurgery were enrolled. Everyone received total intravenous anesthesia by target-controlled infusion of propofol and remifentanil. Two BISTM Quatro sensors mounted on the frontal and zygomatic regions were connected to BIS VistaTM monitors on each patient during general anesthesia.Data from each position were collected and analyzed at the time of awakening ( t1 ) , intubation ( t2 ) , incision ( t3 ) , the end of surgery ( t4 ) , and extubation ( t5 ) . Results At t1 , zygomatic BIS(88.95±6.42) was significantly lower than frontal BIS (84.85±9.64,P<0.01).But during anesthesia,different of BIS value was no statistical significance between the standard frontal position and an alternative zygomatic position(P>0.05). Scatter plot analysis revealed a significant correlation between BIS of frontal positionand that of zygomatic position( R2=0.892,P=0.000) . Conclusion During the anesthesia maintenance period,the zygomatic position can be availably used as an alternative position for monitoring if the operative field renders the standard frontal position unavailable.

Objective To observe the clinical efficacy of fire needling plus Chinese herbal medicine in treating alopecia areata. Method Fifty patients with alopecia areata were randomized into a treatment group of 35 cases and a control group of 15 cases. The treatment group was intervened by fire needling plus Chinese herbal medicine, while the control group was by oral administration of Chinese herbal medicine alone. The clinical efficacies were compared after 3-month treatment.Result The total effective rate was 97.1% in the treatment group versus 73.3% in the control group, and the difference was statistically significant (P<0.05).Conclusion Fire needling plus Chinese herbal medicine is an effective method in treating alopecia areata.

Objective:To explore anti-seizure medication (ASM) treatment patterns, seizures, maternal and fetal outcomes and offspring outcomes of pregnant women with epilepsy (PWWE) who withdraw ASM in the first trimester of pregnancy.Methods:A retrospective analysis was performed on the PWWE database registered in West China Hospital, Sichuan University from January 2009 to October 2022. Patients who withdrew ASM therapy in the first trimester and those who maintained ASM therapy throughout pregnancy were included. Withdrawal in the first trimester was defined as discontinuation of ASM between 0 and 3 months of pregnancy. Sixty-five PWWE (withdrawal group) who withdraw ASM in the first trimester were included, and 130 PWWE (maintained-therapy group) who took ASM throughout pregnancy in West China Hospital during the same period were matched 1∶2. Demographic characteristics, ASM, seizures, maternal and fetal outcomes within 1 year were compared between the 2 groups. In the subgroup analysis, the withdrawal group was divided into a full withdrawal group ( n=53) and a resumption group ( n=12) according to whether the ASM was resumed in the second and third trimesters of pregnancy, and the 2 groups were stratified and compared. Results:In the withdrawal group, the proportion of patients with bachelor degree below [72.3% (47/65) vs 54.6% (71/130), χ 2=5.68, P=0.017], family income less than 5 000 yuan per capita [44.6% (29/65) vs 18.5% (24/130), χ 2=14.98, P<0.001], a family history of epilepsy [12.3% (8/65) vs 3.1% (4/130), χ 2=4.90, P=0.027], and a second pregnancy [43.1% (28/65) vs 26.2% (34/130), χ 2=5.72, P=0.017] was higher than in the maintained-therapy group. The proportion of patients who received multiple ASM was lower in the withdrawal group than in the maintained-therapy group [16.9% (11/65) vs 38.5% (50/130), χ 2=9.35, P=0.002]. In the withdrawal group, the rate of seizures with tonic-clonic seizures during pregnancy [50.8% (33/65) vs 31.5% (41/130), χ 2=6.81, P=0.009] and seizure exacerbation during pregnancy [32.3% (21/65) vs 9.2% (12/130), χ 2=16.41, P<0.001] was higher. The preterm birth rate in the withdrawal group was lower than that in the maintained-therapy group [4.6% (3/65) vs 19.2% (25/130), χ 2=101.70, P<0.001]. The rate of seizure exacerbation during pregnancy was higher in the resumption group than in the full withdrawal group [7/12 vs 26.4% (14/53), χ 2=3.22, P=0.073]. Conclusions:PWWE with a family history of epilepsy and a second pregnancy were more likely to withdraw ASM during pregnancy. After withdrawal, the seizures during pregnancy were significantly worse, but the preterm birth rate of offspring was relatively reduced.

Objective:To learn about the characteristics of natural foci and the spatial distribution of mosquitoes and ticks in Yadong County, Tibet Autonomous Region (Tibet for short).Methods:The eco-geographical characteristics, demographic information, agricultural and animal husbandry data of the natural foci in Yadong County, Tibet were collected from the Yadong County 2020 statistical yearbook, vector data were collected from the Yadong County Center for Disease Control and Prevention, and the data of the meteorological station in Yadong County from 2010 to 2021 were collected from the World Weather Network. In July 2021, a total of 20 mosquito and tick sampling points were selected for field investigation according to the distribution characteristics of vegetation and animal husbandry of Yadong County. The light trap method was used to trap mosquitoes, and the manual inspection and flag dragging method were used to catch ticks. The spatial distribution characteristics of mosquitoes and ticks were analyzed.Results:The natural epidemic foci in Yadong County, Tibet, were high in the north and low in the south, with an elevation difference of about 5 000 m. It was rich in water resources, and the average runoff of Yadong River was 20.1 m 3/s. The climate in the north was cold and dry, and the south was mild and humid. From 2010 to 2021, the annual average station air pressure in Yadong County was 452.8 mmHg (1 mmHg = 0.133 kPa), the maximum monthly average temperature, precipitation and relative humidity of air were 8.7 ℃, 134.5 mm and 81.3%, respectively, all in July. A total of 6 897 diptera insects were attracted by the light trap method, all of which were non-blood-sucking mosquitoes. The total density was 163.77 pieces/(lamp·h), the dominant population was Muscaridae, accounting for 89.69% (6 186/6 897). In different sampling areas, Xiayadong Township collected the most mosquitoes, accounting for 67.17% (4 633/6 897); the others were Yadong County and Shangyadong Township, accounting for 27.36% (1 887/6 897) and 5.47% (377/6 897), respectively. A total 2 014 host animals were examined, and 23 parasitic ticks were caught, of which 20 were of the genus Ixodes and 3 were of the genus Haemophilus. No free ticks were caught in all ticks sampling points. Conclusions:The climate and ecological environment of the natural foci in Yadong County, Tibet have obvious vertical gradient. Mosquitoes and ticks are active, but the density is not high, the density of mosquitoes is generally high in the south and low in the north.

Objective:To investigate the efficacy and safety of peritoneal dialysis (PD) in end-stage renal disease (ESRD) patients with liver cirrhosis (LC).Methods:Clinical data of PD patients receiving regular treatment followed up for≥6 months, and aged≥18 years in the Third Affiliated Hospital of Hebei Medical University Peritoneal Dialysis Center from January 1, 2013 to March 31, 2020 were retrospectively collected. The patients were divided into LC-PD group and non-LC-PD group according to whether they had LC or not. Propensity score matching (PSM) was used to match the LC-PD group and the non-LC-PD group with 1∶4 ratio. The baseline clinical data, dialysis adequacy, peritonitis and clinical outcomes between the two groups were compared. Kaplan-Meier survival curve and Log-rank test were used to compare the survival rate and technical survival rate between the two groups.Results:A total of 241 PD patients were included in this study. After PSM, 13 cases in LC-PD group and 52 cases in non-LC-PD group were included. Compared with non-LC-PD group, patients in LC-PD group had lower baseline urine volume ( Z=-3.546, P<0.001) and serum albumin ( Z=-2.609, P=0.009). At the follow-up of 3, 6, 12 and 24 months, total serum protein ( t=-3.319, P=0.002), serum albumin ( t=-4.019, P<0.001), triglyceride ( Z=-2.263, P=0.024), and serum phosphorus ( Z=-2.173, P=0.030) in the LC-PD group were lower than those in non-LC-PD group. During the follow-up period of 2 years, the patients in the LC-PD group had significantly higher serum albumin than baseline values ( χ2=16.901, P=0.001), and there was no statistically significant difference between the two groups ( χ2=0.155, P=0.694). The decline rate of residual kidney Kt/V in the LC-PD group was slower than that in the non-LC-PD group ( χ2=44.589, P<0.001). The incidence of peritonitis in LC-PD group was higher than that in the non-LC-PD group, with a statistically significant difference (0.59/patient-year vs 0.20/patient-year, Z=-2.135, P=0.033). The composition ratio of pathogenic bacteria in both groups was mainly gram-positive bacteria (10/25 vs 11/30) and proportion of Streptococcus in LC-PD group was higher than that in non-LC-PD group (4/10 vs 0/11, P=0.035). The proportion of Escherichia coli in the first peritonitis was higher than that in LC-PD group (4/9 vs 1/22, P=0.017). The Kaplan-Meier survival curve results showed no statistically significant difference in survival rate (Log-rank χ2=0.491, P=0.484) and technical survival rate (Log-rank χ2=0.408, P=0.523) between the two groups. Conclusions:PD is a safe and effective treatment mode for ESRD patients with LC, and the survival rate and technical survival rate are comparable to those patients without LC. The incidence of peritonitis in patients with LC-PD in our dialysis center is higher than that in the non-LC-PD patients, and gram-positive bacterial infections are the mainstay, suggesting that attention should be paid to strengthening patient management and training.

Objective:To observe the clinical outcomes of continued pregnancy in pregnant women with cesarean scar pregnancy (CSP).Methods:A retrospective analysis was performed on the pregnancy outcomes of 55 pregnant women who were diagnosed with CSP at the Second Affiliated Hospital of Army Medical University during the first trimester of pregnancy from August 1st, 2018 to October 31st, 2021 and strongly requested to continue the pregnancy.Results:Of the 55 pregnant women, 15 terminated the pregnancy in the first trimester, 1 underwent hysterotomy at 23 weeks of gestation due to cervical dilation, and 39 (71%, 39/55) continued pregnancy to the third trimester achieving live births via cesarean section. The gestational age of the 39 pregnant women delivered by cesarean section was 35 +6 weeks (range: 28 +5-39 +2 weeks), of whom 7 cases at 28 +5-33 +6 weeks, 20 cases at 34-36 +6 weeks, and 12 cases at 37-39 +2 weeks. The results of pathological examination were normal placenta in 3 cases (8%, 3/39), placenta creta in 4 cases (10%, 4/39), placenta increta in 9 cases (23%, 9/39) and placenta percreta in 23 cases (59%, 23/39). Among the 36 pregnant women who were pathologically confirmed as placenta accreta spectrum disorders (PAS) after surgery, the last prenatal ultrasonography showed placenta previa in 27 cases (75%, 27/36) and not observed placenta previa in 9 cases. The median intraoperative blood loss, autologous blood transfusion, and allogeneic suspended red blood cell infusion of 39 pregnant women during cesarean section were 1 000 ml (300-3 500 ml), 300 ml (0-2 000 ml) and 400 ml (0-2 400 ml), respectively. The uterine preservation rate was 100% (39/39), and only 1 case received cystostomy due to intracystic hemorrhage. The birth weight of the newborn was 2 580 g (1 350-3 800 g), and 1 case of mild asphyxia. Conclusions:Pregnant women with CSP who continue pregnancy under close monitoring after adequate ultrasound evaluation and doctor-patient communication could achieve better maternal and infant outcomes, but pregnant women with CSP are highly likely to continue pregnancy and develop into PAS. Effective hemostasis means and multidisciplinary team cooperation are needed in perinatal period for ensuring maternal and fetal safety.

Objective:To explore the clinical characteristics of paroxysmal kinesigenic dyskinesia (PKD) secondary to pseudohypoparathyroidism (PHP), so as to improve the clinicians′ understanding of the disease.Methods:The clinical data of 2 cases of PKD secondary to PHP in Beijing Tiantan Hospital, Capital Medical University from June 2022 to October 2022 were summarized, and the related literature was reviewed to analyze the pathogenesis, clinical manifestations, laboratory examination and imaging characteristics of the disease, as well as its treatment and prognosis.Results:Ten cases of PKD secondary to PHP were previously reported. A total of 12 cases (including these 2 cases) were included in the study, of which 7 were males (7/12) and 5 were females (5/12). The onset age was 8-23 years. The clinical manifestations of the disease included paroxysmal limb torsion, limb stiffness, limb tremor, throwing movements, and dance like movements. There were 3 cases (3/12) who had seizure at the same time. Ten cases (10/12) were induced by exercise, while 2 cases (2/12) were not mentioned the inducing factor. Eleven cases (11/12) with paroxysmal symptoms lasting less than 2 minutes can be relieved automatically. Only 1 case had a family history. Laboratory examination of all patients showed low calcium, high phosphorus and significant elevation of parathyroid hormone. The head CT scans of 10 cases (10/12) showed multiple intracranial calcifications. There were 9 cases (9/12) alone received the supplementation of calcium and active vitamin D, while 3 cases (3/12) were additionally treated with antiepileptic drugs. All cases had good prognosis.Conclusions:PHP is a rare cause of secondary PKD. A small number of patients can have seizures at the same time. Most patients have a good prognosis after receiving calcium and active vitamin D supplementation.

Objective: To investigate the efficacy and safety of Posaconazole (Posa) in prophylaxis and salvage treatment of invasive fungal infections (IFI) during neutropenia in pediatric patients with leukemia. Methods: A total of 18 pediatric patients (55 case-time) with leukemia in neutropenia stage receiving Posa treatment from December 2015 to August 2017 in Zhujiang Hospital of Southern Medical University, were analyzed retrospectively.Taking one induction chematherapy or one consolidation chemotherapy stage receiving Posa treatment was defined as 1 case-time. Results: Out of 18 participants, 13 cases were patients with acute myeloid leukemia (AML) and 5 cases were patients with acute lymphocytic leukemia (ALL), including 36 males and 19 females.Median age of the participants was 7 years, ranged from 10 months to 14 years.Out of 55 case times, 45 of them were of primary prevention and the neutropenia periods ranged from 4 to 46 days, with the median of 15 days, and 93.33% of them were prevented from fungal infection.However, 3 of the 45 cases had sudden fungal infections and the Voriconazole was an effective treatment, and no one died.Six cases in this study experienced secondary prevention, and no patient experienced reinfection.The neutropenia terms of the 6 cases ranged from 10 to 17 days, with the median of 14 days.Four patients who suffered from Voriconazole and/or Carbophenol therapy failure received Posa as a rescue therapy and the response rate was 100%.None of patients had Posa intolerance due to severe adverse reaction and no Posa treatment-related grade Ⅱ toxic effects occurred. Conclusions Posa is an effective and safe therapy for pediatric patients with leukemia and IFI, and available for long-time usage.Serious adverse reaction is rare.
