Multi-stage optimization strategy based on contextual analysis to create M-health components for case management model in breast cancer transitional care: the CMBM study as an example.

BACKGROUND: None of the early M-Health applications are designed for case management care services. This study aims to describe the process of developing a M-health component for the case management model in breast cancer transitional care and to highlight methods for solving the common obstacles faced during the application of M-health nursing service. METHODS: We followed a four-step process: (a) Forming a cross-functional interdisciplinary development team containing two sub-teams, one for content development and the other for software development. (b) Applying self-management theory as the theoretical framework to develop the M-health application, using contextual analysis to gain a comprehensive understanding of the case management needs of oncology nursing specialists and the supportive care needs of out-of-hospital breast cancer patients. We validated the preliminary concepts of the framework and functionality of the M-health application through multiple interdisciplinary team discussions. (c) Adopting a multi-stage optimization strategy consisting of three progressive stages: screening, refining, and confirmation to develop and continually improve the WeChat mini-programs. (d) Following the user-centered principle throughout the development process and involving oncology nursing specialists and breast cancer patients at every stage. RESULTS: Through a continuous, iterative development process and rigorous testing, we have developed patient-end and nurse-end program for breast cancer case management. The patient-end program contains four functional modules: "Information", "Interaction", "Management", and "My", while the nurse-end program includes three functional modules: "Consultation", "Management", and "My". The patient-end program scored 78.75 on the System Usability Scale and showed a 100% task passing rate, indicating that the programs were easy to use. CONCLUSIONS: Based on the contextual analysis, multi-stage optimization strategy, and interdisciplinary team work, a WeChat mini-program has been developed tailored to the requirements of the nurses and patients. This approach leverages the expertise of professionals from multiple disciplines to create effective and evidence-based solutions that can improve patient outcomes and quality of care.

HU value of chest CT vertebral body in the opportunistic screening of type 2 diabetes mellitus osteoporosis / 中国组织工程研究

BACKGROUND:Some studies have shown that the hounsfield units(HU)value based on lumbar CT can be used to screen osteoporosis.At present,the number of patients with pulmonary infection has increased;the number of patients with pulmonary infection and type 2 diabetes is also increasing,which increases the utilization rate of chest CT. OBJECTIVE:To investigate the role of lumbar 1 vertebral body HU value based on chest CT in the screening of type 2 diabetes mellitus osteoporosis. METHODS:The clinical data of 244 patients with type 2 diabetes mellitus treated in the First Affiliated Hospital of Chengdu Medical College from June 2020 to June 2022 were analyzed retrospectively.The bone mineral density was obtained by dual-energy X-ray absorptiometry.According to WHO's diagnostic criteria for osteoporosis,the subjects were divided into the non-osteoporosis group(n=120)and the osteoporosis group(n=124).The general condition,T value and HU value of lumbar 1 vertebra in chest CT were compared,and the relationship between the HU value and T value of each position was analyzed and the accuracy of type 2 diabetes mellitus osteoporosis was evaluated. RESULTS AND CONCLUSION:(1)There was no significant difference in sex,age,body mass index,glycosylated hemoglobin,mean blood glucose,calcium(Ca),phosphorus(P),time of type 2 diabetes mellitus,history of hypertension and history of hyperlipidemia between the two groups(P>0.05).(2)The HU value was positively correlated with the lowest T value of the hip(r=0.619,P<0.01);the HU value was positively correlated with the hip T value(r=0.584,P<0.01),and the HU value was positively correlated with the femoral neck T value(r=0.641,P<0.01).When the HU value was 98,the prediction of type 2 diabetes mellitus osteoporosis had good accuracy,and the sensitivity was 70.8%.(3)It is concluded that the HU value of the lumbar 1 vertebra based on chest CT examination is of good value for osteoporosis screening in patients with type 2 diabetes mellitus,and may be an opportunistic and cost-free supplementary screening method for type 2 diabetes mellitus osteoporosis.

Molecular analysis of the new allele 803delC of subtype B / 中国输血杂志

【Objective】 To analyze the serological characteristics and molecular mechanism of a novel B subtype allele 803delC. 【Methods】 ABO blood group was detected by serological method. Sequence-specific primer polymerase chain reaction (PCR-SSP) was used to detect ABO blood group genes. The coding region of exon 1-7 of ABO gene was detected by Sanger sequencing to determine the mutation site. 【Results】 Serological identification of patients was with forward O-type and reverse B-type. The result of PCR-SSP genotyping was A/O. There was A gene, which was not consistent with serological results. Further Sanger double-strand sequencing revealed that the C-base was deleted at position 803 of exon 7 on the basis of ABO*B. 01/ABO*O. 01.01. The mutation eventually leads to the amino acid substitution of p. Ala268Gly and p. Phe269Ser and the production of new open reading frame starting at position 269, with the new open reading frame No.20 amino acid being stop codon, resulted in the termination of B gene expression. Further single-strand sequencing of the ABO gene revealed that the mutation was located in the ABO*B. 01 gene. The mutation was submitted to the NCBI database with the number OR343908. 【Conclusion】 A new ABO allele leading to B variant has been found in Chinese population. Genetic detection can be used to identify the ambiguous blood group with discrepancy between forward and reverse blood grouping.

But Titmus near stereopia showed no difference (P > 0.05). ConclusionBehavioral vision training could improve vision and strabismus after stroke.

Analysis of laboratory tests and prevention strategies for hemolytic disease of the fetus and newborn caused by anti-M / 中国输血杂志

【Objective】 To analyze the application of serological test results in the diagnosis and treatment of anti-M-induced hemolytic disease of the fetus and newborn(HDFN), and to explore HDFN prevention strategies. 【Methods】 The serological test results of 12 cases of HDFN caused by anti-M diagnosed in our laboratory from January 2017 to December 2023 were retrospectively analyzed, including blood group identification of mothers and children, serum total bilirubin/hemoglobin/antibody titer test, and three hemolysis tests in newborns. Clinical data of the children and mothers were collected, including pregnancy history, blood transfusion history, prenatal antibody testing, history of intrauterine blood transfusion and gestational week of delivery, and the prognosis of the children was followed up. 【Results】 All 12 cases of fetal neonatal hemolytic disease due to anti-M were RhD+ MN phenotype newborn born to RhD+ NN mother, with maternal- fetal incompatiblility in MN blood groups. In the ABO blood group system, ABO incompatibility between mother and child accounted for 41.7%(5/12).None of the mothers had a history of blood transfusion, and the median titer of the test at 4℃ was 32, and the median titer at 37℃ was 4. The mothers of 3 cases had a history of multiple intrauterine blood transfusions, with an incidence of 25%(3/12). One case had an abnormal first pregnancy, with an incidence of 8.3%(1/12), and seven cases had an abnormal pregnancy with a miscarriage, with an incidence of abnormal pregnancy and birth history of 58.3%(7/12). There were 6 cases of premature labor, with an incidence of 50%(6/12). The mothers in three cases underwent regular obstetric examination and the specificity of the antibodies was determined, accounting for 25%(3/12). Twelve children had free antibodies with a median titer of 6 at 4℃ and 2 at 37℃. Two children had anti-M antibodies that were not reactive at 37℃, with a negative rate of 16.7%(2/12). The positive rate of DAT and elution test was respectively 8.3%(1/12) and 16.7%(2/12) in the children. The median minimum hemoglobin value was 75 g/L, and all 12 children received blood transfusions. The median peak total bilirubin value was 157.5 μmol/L, and none of them reached the threshold for blood exchange. The rate of delayed anemia was 16.7%(2/12), the postnatal mortality rate was 8.3%(1/12), and 11 children was free of growth and neurodevelopmental delay in prognosis. 【Conclusion】 Anti-M can cause severe HDFN, which can also occur in primigravida. The intensity of antibody titer does not correlate with the severity of the disease, and it is prone to cause delayed anemia, which should be monitored regularly according to the serological characteristics of anti-M and clinical symptoms, and should be treated timely.

Objective To analyze the demographic data,CT characteristics,treatment methods and follow-up results of patients with spontaneous isolated dissection of celiac artery(SIDCA)and to explore the selection of treatment strategy for SIDCA.Methods Medical records of 31 patients diagnosed as SIDCA were selected.The patients were divided into 2 groups,symptomatic group and asymptotic group.Demographic data,morbidity season,CT characteristics(type,distance of the entry site from the origin of the artery,dissection length,compression rate of the true lumen,branches involvement,organ ischemia,coexisting vasculopathy),treatment methods,and follow-up results were analyzed.Results Thirty-one patients were identified by CT contrast scan,22 were symptomatic and 9 were asymptomatic.22 patients were first diagnosed in cooler season,compared with 9 patients in warmer season(22 vs 9,Fisher's exact test,P=0.029).The difference between symptomatic and asymptomatic groups about branches involvement in patients was significant(8/14 vs 0/9,Fisher's exact test,P=0.007).Treatment included observation in 24,endovascular intervention in 6 patients and surgical repair in 1 patient.No patient required bowel resection.The mean follow-up period was 13.75 months.Except for 2 patients,the condition of the remaining patients improved or stabilized during follow-up.Conclusion The difference between symptomatic and asymptomatic groups about branches involvement in patients is significant.Initial conservative treatment may be adequate for patients without end organ malperfusion or aneurysm formation or aneurysm rupture in SIDCA.Additionally,during the cooler season,visceral artery should be observed carefully on abdominal contrast CT,especially in the patient with abdominal pain,to avoid misdiagnosis.

Analgesic efficacy of oxycodone after cesarean section and its effects on pain factors / 中国基层医药

Methods:To investigate the analgesic efficacy of oxycodone after cesarean section and its effects on pain factors.Methods:A total of 100 pregnant women who underwent cesarean section in Taizhou Hospital of Zhejiang Province from August 2022 to March 2023 were included in this prospective study. They were divided into an observation group ( n = 50) and a control group ( n = 50) using a random number table method. Sufentanil was used for postoperative analgesia in the control group, and oxycodone was used for postoperative pain in the observation group. At 6, 12, 24, and 48 hours after surgery, visual analogue scale (VAS) scores of incision pain and uterine contraction pain and the Ramsay score were compared between the two groups. Before and 48 hours after surgery, pain factors (prostaglandin E 2, substance P, and norepinephrine) were compared between the two groups. At 48 hours after surgery, sleep quality, satisfaction with pain relief, and the incidence of adverse reactions were compared between the two groups. Results:The VAS scores of incision pain in the observation group were lower than those in the control group at the studied time points after surgery [6 hours: (2.35 ± 0.31) points vs. (2.78 ± 0.43) points; 12 hours: (5.08 ± 0.64) points vs. (5.67 ± 0.51) points; 24 hours: (4.76 ± 0.35) points vs. (5.12 ± 0.42) points; 48 hours: (2.18 ± 0.37) points vs. (2.54 ± 0.42) points, t = 5.74, 19.87, 4.66, 4.55, all P < 0.001]. At 6, 12, 24, and 48 hours after surgery, the VAS scores of uterine contraction pain in the observation group were significantly lower than those in the control group at the studied time points after surgery [6 hours: (2.41 ± 0.26) points vs. (2.85 ± 0.32) points; 12 hours: (4.98 ± 0.49) points vs. (5.41 ± 0.65) points; 24 hours: (4.65 ± 0.31) points vs. (4.98 ± 0.28) points; 48 hours: (2.04 ± 0.26) points vs. (2.43 ± 0.30) points, t = 7.55, 3.74, 5.59, 6.95, all P < 0.001]. There was no significant difference in Ramsay score between the two groups at 6, 12, 24, and 48 hours after surgery ( t = 0.44, 0.51, 0.78, 0.42, all P > 0.05). At 48 hours after surgery, prostaglandin E 2, substance P, and norepinephrine levels in the observation group were significantly lower than those in the control group ( t = 14.22, 9.05, 14.74, all P < 0.001). At 48 hours after surgery, The Pittsburgh Sleep Quality Index score in the observation group was significantly higher than that in the control group ( t = 4.64, P < 0.05). The overall satisfaction with postpartum analgesia in the observation group was significantly higher than that in the control group ( χ2 = 4.40, P < 0.05). There was no significant difference in the incidence of adverse reactions between the two groups ( χ2 = 0.33, 1.08, 0.38, 0.33, all P > 0.05). Conclusion:Oxycodone has a better analgesic effect on cesarean sections than sufentanil. Oxycodone can inhibit the release of pain factors and thereby reduce pain.

Objective:To investigate the effect of penehyclidine hydrochloride on respiratory mechanics, arterial blood gas, and inflammatory factors in patients undergoing one-lung ventilation during thoracoscopic lobectomy.Methods:A total of 100 patients who underwent thoracoscopic lobectomy with one-lung ventilation at Jinhua Central Hospital from January to November 2022 were included in this randomized controlled study. They were divided into groups A and B ( n = 50 per group) using a random digital number table. Patients in group A received an intravenous infusion of 0.02 mg/kg of pentylenethyclidine hydrochloride 30 minutes before surgery, while patients in group B received an equal amount of 0.9% sodium chloride injection 30 minutes before surgery. Clinical indicators, respiratory mechanical indicators (peak airway pressure, lung compliance), arterial blood gas analysis indicators (blood oxygen saturation, arterial pressure of oxygen, oxygenation index), inflammatory factor levels (interleukin-6, interleukin-8, tumor necrosis factor level-α), and pulmonary complications were compared between the two groups. Results:There were no significant differences in mechanical ventilation time or total infusion volume between the two groups (both P > 0.05). At the end of surgery (T1) and 1 day after surgery (T2), peak airway pressure in group A was (17.43 ± 2.69) cm H 2O and (16.81 ± 2.28) cm H 2O (1 cm H 2O = 0.098 kPa), respectively, which were significantly lower than (19.23 ± 3.40) cm H 2O and (18.29 ± 2.06) cm H 2O in group B, respectively ( t = 2.94, 3.41, P = 0.002, < 0.001). At T1 and T2, lung compliance in group A was (34.67 ± 2.93) cm H 2O and (36.26 ± 3.11) cm H 2O, respectively, which were significantly higher than (32.23 ± 2.85) cm H 2O and (33.84 ± 2.87) cm H 2O in group B, respectively ( t = 4.22, 4.04, P = 0.000, < 0.001). At T1 and T2, blood oxygen saturation, arterial partial pressure of oxygen, and oxygenation index in group A were significantly higher than those in group B ( t = 8.12, 3.07, 10.47, 3.16, 3.81, 4.15, all P < 0.05). At T1 and T2, interleukin-6, interleukin-8, and tumor necrosis factor-α levels in group A were significantly lower than those in group B ( t = 11.67, 13.55, 9.60, 15.71, 6.13, 11.50, all P < 0.001). The incidence of complications in group A was 4% (2/50), which was significantly lower than 16% (8/50) in group B ( χ2 = 4.00, P < 0.05). Conclusion:Penehyclidine hydrochloride has a good effect on respiratory mechanics, arterial blood gas, and inflammatory factors in patients undergoing thoracoscopic lobectomy with one-lung ventilation and thereby deserves clinical promotion.

Objective:To investigate the knowledge and compliance status of prevention and control of brucellosis among high-risk populations in counties and districts with high incidence of brucellosis in Xinjiang Uygur Autonomous Region (Xinjiang for brief), and to provide scientific basis for prevention and control of brucellosis and health education for high-risk populations.Methods:Huocheng County, a high incidence county of brucellosis in Xinjiang, was selected as the survey site. Three to six townships were selected, and two to three administrative villages were selected from each township as the survey villages. People over 18 years old and engaged in livestock breeding such as cattle and sheep breeders, livestock product processors, veterinarians and medical personnel were selected as the survey subjects. Face-to-face surveys were conducted by professional trained investigators in autumn and winter (December 2019 to January 2020) and spring and summer (April to July 2020). The survey included general demographic information, awareness of brucellosis prevention and control knowledge and the use of protective equipment.Results:A total of 600 people were surveyed, and 597 people completed the questionnaire, with an effective response rate of 99.50% (597/600). The overall awareness rate of brucellosis prevention and control knowledge was 68.23% (10 184/14 925), among which the awareness rate of clinical symptoms of human infection with brucellosis was high, at 73.53% (3 073/4 179). There were statistically significant differences in the awareness rate of main source of infection, main transmission route and clinical symptoms of human infection with brucellosis among people of different gender, age, nationality, education level and occupation ( P < 0.05). Among them, the awareness rate of clinical symptoms of human infection with brucellosis among veterinarians and medical personnel was 85.38% (514/602). The utilization rate of protective equipment such as rubber shoes and work clothes was high, which was 63.48% (379/597) and 60.97% (364/597), respectively. There were statistically significant differences in the utilization rate of protective equipment among different nationality, education level and occupation ( P < 0.05). Among them, The utilization rate of work clothes was the highest among people with college education or above, veterinarians and medical personnel, which was 82.61% (57/69) and 93.02% (80/86), respectively. Conclusions:The overall awareness rate of brucellosis prevention and control knowledge in high-risk groups in Huocheng County of Xinjiang is low, especially among high-risk groups such as those who are illiterate or have little literacy, and farmers, the awareness rate is low and the awareness of prevention and control is weak. There is a risk of brucellosis infection. It is necessary to further strengthen the education of brucellosis prevention and control knowledge among these groups.

High mobility group box-1 inhibition reduces expression of matrix metalloproteinase-9 in astrocytes in rats after spinal cord injury / 中华创伤骨科杂志

Objective:To investigate the role and underlying mechanisms of inhibiting high mobility group box-1 (HMGB1) in the expression of matrix metalloproteinase-9 (MMP-9) in spinal cord astrocytes (AS) in rats after spinal cord injury (SCI).Methods:After an SCI model was established in Sprague-Dawley (SD) rats using a modified Allen's Weight-Dropping method and ethyl pyruvate (EP) or glycyrrhizin (GL) was used to inhibit the effect of HMGB1, the rats were divided into a sham group, an SCI group, an SCI+EP (50 mg/kg) group, and an SCI+GL (100 mg/kg) group. The expression levels of glial fibrillary acid protein (GFAP) and MMP-9 in spinal cord AS were observed. After the spinal cord AS in SD rats was cultured and incubated by the oxygen-glucose deprivation/reoxygenation (OGD/R) procedure, the expression of MMP-9 protein was detected at 6 h/R 6 h, 12 h, 24 h, and 48 h after OGD. The time point with the highest expression was chosen in the subsequent experiments as an OGD/R group. HMGB1 was inhibited by HMGB1 shRNA or EP to observe the effect of HMGB1 on the expression of MMP-9 protein in AS treated with OGD/R. Then, toll-like receptor 4 (TLR4) inhibitor, TIR-domain-containing adaptor inducing interferon- β (TRIF) inhibitor, and nuclear factor-kappa B (NF- κB) inhibitor were used to investigate the effects of TLR4/TRIF/NF- κB signaling pathway during the regulation of HMGB1 on MMP-9 in vitro. Results:Western blot showed that the expression of MMP-9 protein in the spinal cord was significantly increased in rats at 1 d after SCI, and the expression of MMP-9 protein in the SCI+EP group and the SCI+GL group was significantly lower than that in the SCI group ( P<0.001). Immunofluorescence showed that GFAP and MMP-9 proteins were co-localized in the spinal cord after SCI, and the expression of GFAP and MMP-9 proteins in the SCI+EP and SCI+GL groups was significantly lower than that in the SCI group ( P<0.05). Since the expression of MMP-9 protein in the spinal cord AS cultured in vitro was significantly higher in the OGD 6h/R 12h group than that in the normal group and the OGD 6h/R 6h, 24, and 48 h groups, the OGD 6h/R 12h was taken as the OGD/R group. The MMP-9 protein expression in AS in the OGD/R+HMGB1 shRNA group and the OGD/R+EP group was significantly lower than that in the OGD/R group ( P<0.001). In the cultured AS, moreover, inhibiting TLR4, TRIF, and NF- κB reduced MMP-9 protein expression after OGD 6 h/R 12 h when compared with that in the OGD/R group ( P<0.001). Conclusions:HMGB1 inhibition may result in a reduction in MMP-9 expression both in the spinal cord AS in SCI rats and in AS after OGD/R treatment in vitro. HMGB1 may regulate MMP-9 protein expression in AS after OGD/R treatment via the TLR4/TRIF/NF- κB signal pathway.

Spatial transcriptome analysis of long non-coding RNAs reveals tissue specificity and functional roles in cancer / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Long non-coding RNAs (lncRNAs) play a significant role in maintaining tissue morphology and functions, and their precise regulatory effectiveness is closely related to expression patterns. However, the spatial expression patterns of lncRNAs in humans are poorly characterized. Here, we constructed five comprehensive transcriptomic atlases of human lncRNAs covering thousands of major tissue samples in normal and disease states. The lncRNA transcriptomes exhibited high consistency within the same tissues across resources, and even higher complexity in specialized tissues. Tissue-elevated (TE) lncRNAs were identified in each resource and robust TE lncRNAs were refined by integrative analysis. We detected 1 to 4684 robust TE lncRNAs across tissues; the highest number was in testis tissue, followed by brain tissue. Functional analyses of TE lncRNAs indicated important roles in corresponding tissue-related pathways. Moreover, we found that the expression features of robust TE lncRNAs made them be effective biomarkers to distinguish tissues; TE lncRNAs also tended to be associated with cancer, and exhibited differential expression or were correlated with patient survival. In summary, spatial classification of lncRNAs is the starting point for elucidating the function of lncRNAs in both maintenance of tissue morphology and progress of tissue-constricted diseases.

Evolutionary Law of Syndrome and Syndrome Elements during the Malignant Transformation of Chronic Hepatitis B / 中医杂志

ObjectiveTo clarify the evolutionary laws of syndromes and syndrome elements at different stages during the malignant transformation of chronic hepatitis B （CHB）. MethodsA total of 671 patients with hepatitis B virus infection， who were admitted to the outpatient and inpatient departments of Dongzhimen Hospital of Beijing University of Chinese Medicine and The Fifth Medical Center of Chinese PLA General Hospital from July 1st， 2020 to June 30th， 2021， were included， involving 120 cases of CHB， 340 cases of hepatitis B liver cirrhosis （HBLC）， 64 cases of precancerous lesions with hepatitis B liver cirrhosis （PLHC）， and 147 cases of hepatitis B liver cirrhosis with hepatocellular carcinoma （HCC）. A Survey form of traditional Chinese medicine syndrome during malignant transformation of chronic hepatitis B was designed， and the general information， auxiliary examination and the four examinations results were collected. Factor analysis and K-means clustering were used to determine and statistically analyze the syndrome and syndrome elements. ResultsFive traditional Chinese medicine （TCM） syndrome types were identified in CHB patients， while there were six TCM syndrome types in HBLC， PLHC and HCC stages. Among CHB patients， the main syndromes were liver constraint and spleen deficiency （53.33%） and liver-gallbladder damp-heat （21.67%）， and the dominant syndrome elements were qi stagnation （27.60%）， heat （17.71%） and qi deficiency （17.71%）. In the HBLC stage， the syndromes were mainly blood stasis obstructing the collaterals （23.83%） and liver constraint and spleen deficiency （22.35%）， with dominant syndrome elements being blood stasis （19.25%）， dampness （17.46%）， and qi deficiency （15.01%）. For the PLHC stage， the primary syndrome types were blood stasis obstructing the collaterals （29.68%） and liver-kidney yin deficiency （20.31%）， and the leading syndrome elements were blood stasis （22.12%）， yin deficiency （15.93%）， and qi deficiency （15.04%）. In the HCC stage， the syndrome was dominated by blood stasis obstructing the collaterals （33.34%） and liver-kidney yin deficiency （19.73%）， with the main syndrome elements being blood stasis （24.52%）， yin deficiency （16.09%）， and qi deficiency （15.33%）. During the progression of CHB to malignancy， there was a gradual decrease in excess syndromes including liver-gallbladder damp-heat and water-dampness internal obstruction from 21.67% to 19.04%. In contrast， deficiency syndromes including liver-kidney yin deficiency and spleen-kidney yang deficiency increased from 15.83% to 31.97%. Additionally， excess syndrome elements including qi stagnation， heat and dampness decreased from 59.89% to 34.48%， while deficiency syndrome elements including qi deficiency， yin deficiency and yang deficiency increased from 32.30% to 41.00%. ConclusionDuring the malignant transformation of CHB， there exists a progression of syndrome and syndrome elements， shifting from qi stagnation， heat and qi deficiency to blood stasis （predominantly excess）， dampness and qi deficiency， and then to blood stasis （predominantly deficiency）， yin deficiency and qi deficiency， characterized by “deficiency-excess complex， and shift from excess to deficiency”.

Washed RBCs of type B and O can be used for B(A) blood type transfusion.

Efficacy of Combination of Camrelizumab with Anlotinib as Third-line Therapy for Patients with Advanced Non-small Cell Lung Cancer / 肿瘤防治研究

Objective To investigate the clinical efficacy and related adverse reactions of the combination of camrelizumab with anlotinib as the third-line therapy on advanced non-small cell lung cancer. Methods We retrospectively analyzed the clinical data of 84 patients with advanced non-small cell lung cancer after second-line treatment. According to different treatment methods, 44 patients who received camrelizumab combined with anlotinib were included in the observation group, and 40 patients who received anlotinib alone were included in the control group. The PFS, ORR, DCR and incidence of adverse reactions were analyzed and compared between the two groups. Results The median PFS of the observation group was longer than that of the control group (7.0 vs. 5.6 months, P=0.001). No statistically significant difference was observed in ORR, DCR, the incidence of adverse reactions or the incidence of adverse reactions above grade 3 between two groups (all P > 0.05). Conclusion The clinical efficacy of camrelizumab combined with anlotinib as third-line therapy on advanced non-small cell lung cancer is better than anlotinib alone, and the safety is good.

Bispecific antibodies in cancer therapy: Target selection and regulatory requirements

In recent years, the development of bispecific antibodies (bsAbs) has been rapid, with many new structures and target combinations being created. The boom in bsAbs has led to the successive issuance of industry guidance for their development in the US and China. However, there is a high degree of similarity in target selection, which could affect the development of diversity in bsAbs. This review presents a classification of various bsAbs for cancer therapy based on structure and target selection and examines the advantages of bsAbs over monoclonal antibodies (mAbs). Through database research, we have identified the preferences of available bsAbs combinations, suggesting rational target selection options and warning of potential wastage of medical resources. We have also compared the US and Chinese guidelines for bsAbs in order to provide a reference for their development.

Effectiveness of redcore lotion in patients with vulvovaginal candidiasis: a systematic review and Meta-analysis.

OBJECTIVE: To summarize and evaluate the effectiveness and safety of Redcore lotion on treating vulvovaginal candidiasis (VVC) using a systematic review and Meta-analysis of randomized controlled trials. METHODS: A systematic literature search was performed in five English and three Chinese electronic databases up to October 2019. Randomized controlled trials in the treatment for VVC were included; only studies which compared the effectiveness and safety of Redcore lotion plus miconazole with miconazole alone were included. Relative risk (RR) and 95% confidence intervals (CI) were used in the Meta-analysis. RESULTS: Seven studies involving 768 patients suffering from VVC were identified; 468 of the patients were pregnant women (60.9%). Combination group (Redcore lotion plus miconazole) was more effective in reduCIng symptomatic episodes of VVC than miconazole alone, with respect to cure rate (RR, 1.31; 95% CI, 1.09-1.57; P = 0.01), fungal culture negative rate (RR, 1.21; 95% CI, 1.04-1.41; P = 0.01), and effective rate (RR, 1.18; 95% CI, 1.05-1.35; P = 0.01). Subgroup analyses for pregnant women also showed that the combination group had superior outcomes with respect to VVC cure rate (RR, 1.48; 95% CI, 1.16-1.88, P < 0.01), fungal culture negative rate (RR, 1.26; 95% CI; 1.09-1.47; P < 0.01), and effective rate (RR, 1.25; 95% CI, 1.10-1.42; P < 0.01). Additionally, the observed risk of adverse events was lower in the combination medication group (RR, 0.30; 95% CI, 0.14-0.65; P < 0.01). CONCLUSIONS: Though overall quality of individual studies was low, Redcore lotion plus miconazole can significantly improve clinical effectiveness and safety compared with miconazole alone.

Formation of the Looming-evoked Innate Defensive Response during Postnatal Development in Mice / 神经科学通报·英文版

Environmental threats often trigger innate defensive responses in mammals. However, the gradual development of functional properties of these responses during the postnatal development stage remains unclear. Here, we report that looming stimulation in mice evoked flight behavior commencing at P14-16 and had fully developed by P20-24. The visual-evoked innate defensive response was not significantly altered by sensory deprivation at an early postnatal stage. Furthermore, the percentages of wide-field and horizontal cells in the superior colliculus were notably elevated at P20-24. Our findings define a developmental time window for the formation of the visual innate defense response during the early postnatal period and provide important insight into the underlying mechanism.

Patent foramen ovale in patients with cryptogenic stroke: evaluation and secondary prevention / 国际脑血管病杂志

Cryptogenic stroke (CS) is a type of stroke that can not find the exact cause after using the standard clinical examination procedure of stroke. In recent years, many studies have shown that patent foramen ovale (PFO) is closely associated with CS, and its main pathogenesis is paradoxical embolism. In clinical practice, ultrasound is often used for PFO screening. In the context of PFO, the secondary prevention of CS includes drug therapy and PFO closure, but the choice of treatment is still controversial. Screening and evaluation of possible PFO will help to develop secondary prevention strategies for patients with CS, especially those who can benefit from PFO closure.
