ObjectiveTo evaluate the efficacy and safety of Qingyusan capsules in the long-term treatment of mild to moderate active ulcerative colitis （UC） with the syndrome of large intestine dampness-heat. MethodA randomized， controlled design was adopted， and 88 patients with mild to moderate UC and syndrome of large intestine dampness-heat were randomized into a Qingyusan （Qingyusan capsules， 0.8 g·d^-1） group and a control （mesalazine， 0.4 g·d^-1） group， with 44 patients in each group. Three and one patients dropped out in the control and Qingyusan groups， respectively， during the 32 weeks of treatment. The clinical remission rate， mucosal healing rate， and modified Mayo score， TCM symptom score， and short inflammatory bowel disease questionnaire （SIBDQ） score before and after treatment were compared between the two groups. The colonoscopic and pathological changes were observed， and the clinical safety was compared between the two groups. ResultAfter treatment， the clinical remission rate and mucosal healing rate in the Qingyusan group were 72.1% （31/43） and 74.4% （32/43）， respectively， which were higher than those ［26.8% （11/41） and 41.5% （17/41）， respectively］ in the control group （χ²=17.200， χ²=10.843， respectively， both P<0.01）. The treatment in both groups decreased the modified Mayo score， partial Mayo score， and TCM symptom score （P<0.05）， and the decreases in the Qingyusan group were higher than those in the control group （P<0.01）. After treatment， the SIBDQ scores in both groups increased （P<0.05）， and the increase was more pronounced in the Qingyusan group than in the control group （P<0.01）. There was no difference in the incidence of adverse events between the two groups. ConclusionThe clinical efficacy of Qingyusan capsules is remarkable in the long-term treatment of UC with the syndrome of large intestine dampness-heat. Particularly， Qingyusan capsules demonstrates advantages in inducing and maintaining clinical remission， promoting mucosal healing， alleviating TCM symptoms， and enhancing the survival quality of patients， with high safety.

Objective:To explore the effects of fast-track surgery (FTS) combined with acupuncture at Neiguan acupoint on stress indicators and recovery quality in patients during anesthesia of craniocerebral surgery.Methods:According to block randomization method, 120 patients with craniocerebral trauma meeting inclusion criteria in the hospital were divided into three groups between January 2018 and December 2020, 40 in each group. The control group was given routine awakening intervention, intervention 1 group was given routine awakening intervention and acupuncture at Neiguan acupoint, and intervention 2 group was given FTS and treatment of intervention 1 group. At 10 min after entering the room, immediately after tracheal intubation and immediately after extubation, level of serum cortisol (COR) was detected by electrochemical luminescence apparatus. The level of serum dopamine was detected by ELISA. The blood pressure and heart rates were recorded. The recovery quality during anesthesia was compared, including recovery time, recovery time of spontaneous breathing, extubation time and recovery time of orientation. The cognitive function of patients was evaluated by Neurobehavioral Cognitive Status Examination (NSCE). The incidence of intestinal paralysis, nausea and vomiting, and hospitalization time were observed and recorded during treatment.Results:Immediately after tracheal intubation and extubation, systolic blood pressure in intervention 2 group, intervention 1 group and control group were significantly decreased ( F=12.03, 13.96), levels of serum COR ( F=91.40, 53.76), and dopamine ( F=29.72, 69.39) were significantly decreased ( P<0.01). The recovery time of orientation during anesthesia [(39.09±3.12)min vs. (41.57±3.54)min, (43.84±3.28)min, F=34.65] in intervention 2 group was significantly shorter than that of the intervention 1 group and control group ( P<0.01), and hospitalization time [(9.36±1.78)d vs. (10.92±1.81)d, (12.10±1.95)d, F=1.44] was significantly shorter than that of the intervention 1 group and control group ( P<0.05). Conclusion:The FTS combined with acupuncture at Neiguan acupoint can reduce stress level during anesthesia, improve recovery quality and relieve postoperative cognitive dysfunction in patients undergoing craniocerebral surgery.

Objective:To explore the effect of endoplasmic reticulum stressed (ER) on colorectal cancer (CRC) cell proliferation and invasion via ATG5-mediated autophagy pathway and the underlying mechanism.Methods:We performed bioinformatics analysis to identify the expression level of PERK, ATF6 and ATG5 in CRC tissues and adjacent tissues and the correlation between PERK and ATG5 expression in CRC tissues.The expression level of PERK in CRC cell lines was examined by qRT-PCR assay. Cell proliferation was quantified by CCK-8.The invasion of the cells was detected by Transwell.Western blot assay was performed to verify the levels of protein. The levels of autophagy were examined by electron microscopy.Results:PERK and ATF6 expression in CRC tissues was higher than that in the adjacent tissues and PERK expression was higher in CRC cells than intestinal mucosal cells. Expression level of PERK in CRC cell lines HCT116,SW480,HT29,LoVo and colonic mucosa cell lines FHC was 1.51±0.04,3.12±0.05,2.19±0.04,2.38±0.06 and 0.98±0.04 ( P<0.001) .The increased expression of PERK promoted CRC cell proliferation and invasion. PERK expression levels was positively associated with ATG5 expression levels ( r=0.52, P<0.001) and overexpression of PERK accelerated the protein expression of ATG5 (1.00±0.04,3.53±0.07, t=74.61, P<0.001) . ATG5 was highly expressed in CRC tissues. Overexpression of ATG5 could promote proliferation,invasion and accelerate autophagy of CRC cells (the number of autophagosomes in the blank control group,the negative control group and ATG5-Overexpression group was 4.33±1.53, 4.00±1.00, 9.67±2.52, and t=3.14,3.62, P=0.035,0.022, respectively) .ATG5 promoted colorectal cancer cell proliferation and invasion through autophagy pathway. Conclusion:ER stressed-CRC cells could promote CRC cell proliferation and invasion through ATG5-mediated autophagy pathway.

Objective:To investigate the safety, economic effect, and short-term clinical efficacy of ambulatory total hip arthroplasty (THA) in the treatment of hip osteopathy within.Methods:This study retrospectively reviewed patients who underwent 48-hour outpatient THA and conventional primary THA from July 2020 to July 2021. Gender, age, body mass index (BMI), clinical diagnosis, place of resident, length of hospital stay, duration of the surgery, hemoglobin, albumin, C-reactive protein (CRP) and D-dimer before and 1 day after surgery, the visual analogue scale (VAS) was obtained postoperative day 2, hip joint modified Harris score before and 1 month after surgery, readmission and reoperation within 1 month after operation as the data of evaluations were extracted and compared in this study.Results:A totally of 150 cases were involved in this study, which including 75 cases with 48-hour outpatient primary THA and 75 cases with conventional primary THA. There was no significant difference between the two groups in terms of age, sex, BMI, education level, preoperative diagnosis, and preoperative Harris score ( P>0.05), but a significant difference was found in term of residence (χ 2=6.29, P=0.043), that the patients in the outpatient group were all from Zhejiang Province and 48% (36/75) of them were from Hangzhou City. While, in the conventional group, 6 patients were from other provinces. The length of stay was 2.13±0.52 days and operation time was 59.73±18.91 minutes in the outpatient group, which were both shorter than those (6.71±1.44 days and 66.91±22.40 min) in the conventional group ( t=25.91, P<0.001 for the length of hospital stay; t=2.12, P=0.036 for operation time). Compared with the conventional group, outpatient group saved the average hospital cost (4.60±0.44 vs. 5.20±0.72 ten thousand yuan, t=6.16, P<0.001). The VAS on the second day after surgery 3.45±0.75 was higher in the outpatient group than in the conventional group (3.45±0.75 vs. 3.16±0.94 points, t=2.09, P=0.039). The modified Harris score was without statistical significance ( t=0.42, P=0.677) 1 month after surgery in both groups. 75 patients in the outpatient group, 7 patients delayed discharge (were not discharge within 48 hours), and the rate of delayed discharge was 9.3%. Reasons for delayed discharge included poor pain control in two cases, one case had postoperative nausea and vomiting, one case had failed to meet rehabilitation standards, hypotension in one case, the intraoperative infection in one case and postoperative fever within 48 hours in one case. Conclusion:Outpatient THA can reduce the length of hospital stay, operative time and total cost of hospitalization. It has similar safety and early clinical efficacy as conventional THA. However, a small proportion of patients would delay discharge.

Objective:To evaluate the detection accuracy of hepatitis B virus (HBV) serological markers among grassroots medical institutions in the demonstration areas of infectious diseases.Methods:A fixed sampling method was used among the followed-up hepatitis B cohort in general population of six infectious disease demonstration areas nationwide. Blood samples of chosen objects were collected, in which HBsAg and anti-HBs were tested by grassroots medical institutions and were also parallely tested by the third-party platform. The test results were compared between the two groups. Statistical analyses were conducted by SAS 9.4 software.Results:A total of 5 756 and 5 263 samples of HBsAg and anti-HBs were successfully tested, respectively. Comparing the results of HBsAg and anti-HBs from grassroots medical institutions with the results from the third platform, the agreement of HBsAg and anti-HBs was 97.13% and 77.33%, respectively. The Kappa value was 0.56 (95% CI 0.50-0.62) for HBsAg and 0.54 (95% CI 0.52-0.56) for anti-HBs, respectively; and the McNemar tests indicated the difference between the results (all P<0.01). There were also significant differences in agreement of testing results with the third platformin among different regions ( P<0.05 or <0.01). The Kappa values indicated that Jiangsu province and Guangdong province had high accordance rates of HBsAg (0.87 and 0.81, respectively), and Gansu province and Guangdong province had high accordance rates of anti-HBs (Both were 0.74). Regarding the results from the third platform as the standard, the sensitivity of HBsAg testing in grassroots medical institutions was moderate (40.51%) and the specificity was well (99.96%). The sensitivity of anti-HBs testing was substantial (73.18%) and the specificity was well (84.31%). Guangdong province (Youden index: 0.69) and Jiangsu province (Youden index: 0.80) had high identification ability for HBsAg, and for indicator of anti-HBs, Gansu province (Youden index: 0.78) and Guangdong province (Youden index: 0.76) had high identification ability. Conclusion:There are certain differences in results of HBV serological markers tests between the grassroots medical institutions in the demonstration areas of infectious diseases and the third platform. Current testing strategies in grassroots medical institutions are suitable for identifying people without hepatitis B infection, while it is necessary to pay attention to the situation of potential false negative error.

Although the flu vaccine is the most effective strategy for preventing influenza currently,the population incidence and mortality of influenza present an unstable trend.Due to the rapid variability of influenza virus,the conventional flu vaccine components and dominant lineage are not matching;more importantly,trivalent influenza vaccine (T IV) contains only A/H3N2,A/H1N1 and B/Victoria lineage,which does not match the B/Yamagata lineage that have prevailed in recent years.Quadrivalent influenza vaccine (QIV) adds the B/Yamagata lineage,and it has been used abroad for susceptible populations.Compared with TIV,QIV provides better protection for susceptible populations and is considered to have better public health benefits.This article reviews the history of development and current status,the safety,immunogenicity,efficacy of prevention and control and cost-effectiveness of QIV,to provide reference for the promotion and implementation of influenza vaccination.

s] Objective To evaluate the effect of comprehensive schistosomiasis control measures with focus on total removal of cattle and sheep in Junshan District,Yueyang City. Methods The retrospective review and field survey were implemented in the pilot villages in Junshan District. The data of Schistosoma japonicum infection status of human,cattle,sheep and Oncome-lania hupensis snails,and density of snails were gathered and modeled in the period of 2006 to 2016. Results The prevalence of schistosome infection in residents in the pilot villages decreased from 3.44％ in 2006 to 0.59％ in 2012(F = 14.501,P =0.013). After removal of all the cattle and sheep in 2013,the prevalence of schistosome infection in the residents decreased to zero in 2016(F=14.148,P=0.033). The density of living snails decreased from 0.8833/0.1 m2 in 2006 to 0.3088/0.1 m2 in 2012(F=76.250,P=0.005). Conclusion The comprehensive schistosomiasis control strategy with focus on cattle and sheep removal is remarkably effective.

Objective To investigate the functional activity and connectivity of the insular cortex at rest in persons with low back pain (LBP).Methods Twelve healthy subjects (male 6,female 6 ; age 24.8 ± 3.3 years) were given fMRI 3.0T scans at rest.Back muscle pain was then induced with an intramuscular injection of 3％ hypertonic saline solution and a second scan was performed.The pain-free and in-pain fMRI data were compared using paired t-tests to highlight any changes in the functional connectivity of the anterior and posterior insular cortex on both sides.Pain severity was quantified using a visual analogue scale (VAS).Results Ratings of LBP severity peaked at 6.02 ± 1.96 on the VAS.The functional connectivity of the inferior insular cortex with the frontal cortex,the thalamus and the parahippocampal gyrus was enhanced when the subjects were in pain,but connectivity with the posterior cingulate cortex,the precuneus,the temporal cortex,the paracentral lobule and the cerebellar tonsil was reduced.The inferior parietal lobule exhibited significantly enhanced connectivity with the anterior insular cortex,but reduced connectivity with the posterior insular cortex.In addition,the medial cingulate cortex displayed decreased functional connectivity with the anterior insular cortex,but increased functional connectivity with the posterior insular cortex when the subjects were in pain.Conclusion This study has revealed impeded functional connectivity of the insular cortex when experiencing LBP at rest.This may possibly be related to pain's disruption of cognition and emotion.

Cationic PLG nanoparticles and liposome were prepared and used as package molecules to pack up pUC18-CpG. The effects of the packed pUC18-CpG on the cellular and humoral immune responses were detected in the mice that were inoculated with pig paratyphoid vaccine. The results showed that compared with the control, the amount of IgG and the titre of specific antibody were significantly increased in the sera of mice immunized with the CpG plasmid entrapped by cationic PLG nanoparticles; the proliferation and induced IL-2 bioactivity of lymphocytes were significantly enhanced in the spleen of the immunized mice; the stimulatory effect of cationic PLG nanoparticles was similar to or stronger than that of cationic liposome. These indicated that cationic PLG nanoparticle could be employed as an effective package molecule to promote the immunostimulatory effect of pUC18-CpG.

The main component of this pill is 2-Octadecanoic acid-4-Palmitic acid-2, 4-Pentanediyl ester separated from chloroform extract of neem oil. The microcapsules coated by the re-curdle method were fabricated with an average particle size of 100-180 microm. The morphological characteristics, incorporation efficiency, carrier reclamation efficiency of the microcapsule were investigated. Kunming mice were used in the experiment, and the anti-fertility effect of the microcapsule on the histology and apoptosis was studied by light and electron microscopy and the flow cytometry. The data obtained clearly indicated that the microcapsule could lead to the payload of medicine, the incorporation efficiency being 90%. After the microcapsules were given to the male mice orally, its anti-fertility effect came into being and could keep the mice in a state of reversible infertility for a long time. The results of histological study and flow cytometry indicate that the mechanism of its anti-fertility effect involves mainly the inhibition of sperm motility and the arrest of spermatogenic process.
