Guided by ZHANG Jiebin's "water-fire of life gate theory"， this paper explored the etiology， pathoge-nesis， and syndrome differentiation-based treatment approach for esophageal cancer. It is proposed that the core pathogenesis of esophageal cancer， derived from the imbalanced state of water and fire in life gate， can be summarized into three manifestations. Firstly， decline of life gate fire leads to failure of qi transformation and accumulation of phlegm and blood stasis； secondly， fire fails to warm the earth resulting in dysfunctional ascending and descending， and qi stagnation and blood stasis； thirdly， deficiency of life gate water contributs to proliferation of cancerous toxins and physical deterioration. In terms of treatment， guided by ZHANG's treatment principles for dysphagia， three treatment methods are proposed， warming and tonifying kidney yang to promote qi transformation through steaming action， warming and nourishing the spleen and stomach to restore central pivot movement， and nourishing kidney water to replenish essence and blood， then support bodily nourishment. Clinical case examples are provided to illustrate the application of these methods.

Objective We aimed to establish the benchmark characteristic map of Fuzi decoction and the determination method of multi-index components,and to clarify the key quality attributes of Fuzi decoction.Methods Fifteen batches of Fuzi decoction substance benchmarks samples were prepared;the high-performance liquid chromatography(HPLC)characteristic spectrum of Fuzi decoction was established;and characteristic peak attribution and similarity analysis were performed.Ginsenosides Rg1,Re,Rf,and Rb1 were used as the index components to establish a method to determine ginseng content in Fuzi decoction.The value range of each quality control index was set at a limit of 70%-130%of the average value,and the quantity transfer analysis was performed on the material basis of 15 Fuzi decoction batches.Results The characteristic spectra of the 15 Fuzi decoction batches had 12 common peaks,and seven characteristic peaks of gallic acid,catechin,paeoniflorin,ginsenosides Rg1,Re,and Rb1,and atractylenolide Ⅲ were identified,with a similarity of more than 0.98.Ginsenosides Rg1,Re,Rf,and Rb1 content ranges were 0.51-0.94,0.34-0.62,0.14-0.27,and 0.41-0.76 mg/g,respectively.The transfer rates of ginsenosides Rg1 and Re,Rf,and Rb1 were 12.05%-26.91%,11.15%-43.71%,and 10.53%-33.23%,respectively.Conclusion The characteristic HPLC of Fuzi decoction and the determination method of Fuzi decoction ginseng content established in this study are accurate,reproducible,and stable,laying the foundation for the quality evaluation of the key chemical properties of Fuzi decoction and its preparation.

With the reform of the national medical and health system entering a new stage of high-quality development of public hospitals,the large-scale implementation of day surgery in hospitals is imminent in the face of increasing patient demand.In this paper,the medical administration management and medical insurance policies related to day surgery in China and their im-pacts were sorted out,and the example of large-scale implementation of day surgery by a specialized ophthalmic medical institu-tion through pre-hospitalization mode was used to illustrate how to use management tools to break through the bottleneck in the promotion process of day surgery,and the positive effect of large-scale development of day surgery on both doctors and patients was expounded.

Objective To explore association between childhood trauma,resilience and non-suicidal self-injury in adolescents.Methods One hundred and fifty-eight first-episode adolescent patients with mood disorders were selected and divided into NSSI group(n=94)and non-NSSI group(n=64)based on presence or absence of NSSI.The Hamilton depression scale(HAMD),Hamilton anxiety scale(HAMA),childhood trauma questionnaire(CTQ-SF)and Connor-Davidson resilience scale(CD-RISC)were used to evaluate the depression and anxiety symptoms,childhood trauma and resilience.Results There were more cases of younger age(16.17±1.67 vs.16.73±1.37),lower education level(30.9% vs.15.6% ),left behind experience(48.9% vs.29.7% ),school bullying(46.8% vs.25.0% ),suicide ideation(85.1% vs.37.5% )and history of attempted suicide(29.8% vs.6.3% )in the group with NSSI compared to those without NSSI.The HAMD score(27.99±5.94 vs.24.19±5.19),HAMA score(18.02±5.94 vs.15.45±4.99),CTQ total score(48.43±15.40 vs.41.97±9.75),emotional abuse score(12.77±6.06 vs.10.19±4.06),and emotional neglect score(11.40±5.34 vs.9.14±3.55)were higher in the group with NSSI,and the differences between the two groups were significant(P<0.05).The total scores of psychological resilience(39.83±10.27 vs.28.66±12.75),resilience(19.59±4.92 vs.12.28±6.47),strength(12.03±3.98 vs.9.99±4.67),and optimism(8.98±2.97 vs.6.47±3.73)in the group without NSSI were higher than those in the group with NSSI(P<0.05).Logistic regression analysis showed that left behind experience(OR=4.494,95% CI:1.192-16.940),school bullying(OR=5.983,95% CI:1.329-26.945),suicidal ideation(OR=13.225,95% CI:2.908-60.146),history of attempted suicide(OR=16.769,95% CI:1.845-152.379),HAMD(OR=1.264,95% CI:1.046-1.626),emotional abuse(OR=1.327,95% CI:1.093-1.612),and resilience(OR=0.468,95% CI:0.266-0.823)were significantly associated with adolescent mood disorders with NSSI(P<0.05).Conclusion Left behind experience,campus bullying,suicidal ideation and attempted suicide,emotional abuse,degree of depression,and psychological resilience may be associated with NSSI behavior in adolescents with mood disorders.

Establishment of vaginal immune defenses at the mucosal interface layer through gene vaccines promise to prevent infectious diseases among females. Mucosal barriers composed of a flowing mucus hydrogel and tightly conjugated epithelial cells (ECs), which represent the main technical difficulties for vaccine development, reside in the harsh, acidic human vaginal environment. Different from frequently employed viral vectors, two types of nonviral nanocarriers were designed to concurrently overcome the barriers and induce immune responses. Differing design concepts include the charge-reversal property (DRLS) to mimic a virus that uses any cells as factories, as well as the addition of a hyaluronic acid coating (HA/RLS) to directly target dendritic cells (DCs). With a suitable size and electrostatic neutrality, these two nanoparticles penetrate a mucus hydrogel with similar diffusivity. The DRLS system expressed a higher level of the carried human papillomavirus type 16 L1 gene compared to HA/RLS in vivo. Therefore it induced more robust mucosal, cellular, and humoral immune responses. Moreover, the DLRS applied to intravaginal immunization induced high IgA levels compared with intramuscularly injected DNA (naked), indicating timely protection against pathogens at the mucus layer. These findings also offer important approaches for the design and fabrication of nonviral gene vaccines in other mucosal systems.

Microcystin-leucine arginine (MC-LR), a potentially carcinogenic toxin, is produced by Cyanobacteria such as Microcystis and Ananabacteria during water bloom. Increasing evidence demonstrated that MC-LR induces male reproductive toxicity, mainly by inducing germ cell apoptosis, destroying cell cytoskeleton, interfering with DNA damage repair pathway, and damaging blood-testicular barrier (BTB), which eventually lead to male sterility. Testicular Sertoli cells are the somatic cells that directly contact with spermatogenic cells in seminiferous tubules. They not only regulate immune response to maintain testicular immune homeostasis by secreting a variety of cytokines and immunosuppressive factors, but also provide the protective effects of spermatogenic cells by forming BTB. MC-LR induces inflammation and apoptosis of Sertoli cells, and destroys the integrity of the BTB, and then causes spermatogenesis dysfunction.

Objective To explore the correlation between childhood trauma and plasma adiponectin levels in patients with depression.Methods A total of 121 patients with depression and 39 healthy controls(control group)were enrolled.Childhood trauma questionnaire(CTQ-SF)was used to assess the experience of childhood abuse and neglect,and the patients with depression were divided into trauma group(n=53)and non-trauma group(n=68)according to the CTQ-SF score.The 17-item Hamilton depression scale-17(HAMD17)and the Hamilton anxiety scale(HAMA)were used to evaluate the severity of depression and anxiety symptoms,respectively.Plasma adiponectin levels of subjects were measured by enzyme-linked immunosorbent assay.Results The plasma adiponectin level of trauma group[3.82(2.44,4.92)μg/mL]was significantly lower than that of non-trauma group[4.64(2.98,6.43)μg/mL,P=0.01]and the control group[6.29(4.54,7.51)μg/mL,P＜0.01].The plasma adiponectin level of non-trauma group was lower than that of the control group(P＜0.01).Correlation analysis showed that plasma adiponectin level in patients with depression was negatively correlated with childhood trauma(r=-0.34,P＜0.01).Multivariate linear regression analysis showed that plasma adiponectin level was negatively correlated with childhood trauma scores in patients with depression(β=-0.05,P＜0.01).Conclusions Patients with depression who have experienced childhood trauma have lower plasma levels of adiponectin,and childhood trauma may be associated with decreased plasma adiponectin levels in patients with depression.

Objective To explore whether indoor light-assisted therapy can rapidly improve depression and anxiety symptoms in patients with depression,as well as the safety of indoor-light-assisted therapy.Methods From September 2021 to December 2022,patients with depression were recruited from the Mental Health Center of the First Hospital of Hebei Medical University.According to the random number table method,patients were divided into test group and control group.The test group was treated with light therapy 30 minutes from 7:30 am to 8:00 am daily for 2 weeks in addition to antidepressant therapy.Antidepressant therapy was continued after completion of light therapy and patients were followed up for 2 weeks.The control group was treated with regular antidepressants throughout the four-week trial.Hamilton depression scale(HAMD17)and the Hamilton anxiety scale(HAMA)were used to assess the clinical symptoms at the baseline and the end of every week of treatment.Safety was evaluated using patient adverse events,anterior segment photography and visual testing.Results A total of 80 patients were enrolled,including 40 in the test group and 40 in the control group.The data of dropped were processed for missing values and then included in the statistical analysis.At the 1st(20.0％vs.0.0％)and 2nd(45.0％vs.17.5％)weekend of treatment,the response rate in the test group was significantly higher than that in the control group.There was an interaction between the time point and the group in HAMD17 total score(F=9.66,P<0.01).The scores of HAMD17 at the end of every week in the test group were significantly lower than that in the control group(P<0.05).There were significant differences in the reduction rate of total score in HAMD17[33.3％(25.0％,43.3％)vs.13.9％(9.9％,19.8％)]and HAMA[22.4％(16.5％,35.3％)vs.14.2％(4.4％,26.9％)]between the two groups(P<0.05).Incidences of adverse effect were not significantly different between the two groups(12.5％vs.10.0％,P=1.00).There were no severe adverse events or mania was reported in the test group and the eye examination showed no abnormality.Conclusion Compared with antidepressant therapy alone,indoor light therapy combined with antidepressant can quickly improve depression and anxiety symptoms in patients with depression,shorten the duration of depression treatment,and has good safety.

Objective:To evaluate the effectiveness and safety of 3.5% lidocaine hydrochloride ophthalmic gel for eye surface anesthesia.Methods:A multicenter, randomized, double-blind, placebo controlled clinical trial was conducted in 10 hospitals in China from August 2018 to April 2019 under the approval of an Ethics Committee of Beijing Hospital (No.2018BJYYEC-014-02). A total of 220 fellow eyes of 220 subjects who received ocular surgery in one eye were actually enrolled according to a same included criteria in different institutes.The 220 eyes were randomly divided into control group and trail group.Two drops of lidocaine hydrochloride gel were dropped at about 5 mm away from corneal limbus at 6 o'clock direction of experimental eye of the trail group, and the blank gel was used in the eyes of the control group in the same way.The pain sensation was assessed with a 0.3 mm toothless micro forceps on conjunctiva within a specified time, and ''pain'' or ''no pain'' was answered by the subjects.The primary effective indexes, namely the number of eyes and percentage of ''no pain'' within 5 minutes following dropping, as well as the secondary indexes including the onset time point of the drug and the duration of anesthesia were recorded and evaluated.Safety evaluation took ocular and system adverse events into account.Results:Within 5 minutes after dropping, ''no pain'' occurred in 104 eyes (94.55%) and 29 eyes (26.36%) in the trail group and control group, respectively, showing a significant difference between the two groups ( χ2=106.948, P<0.001). And there was a significant difference in anesthesia onset time between the trail group and control group (40.0 seconds vs. 300.0 seconds) ( Z=-15.17, P<0.001). The duration of anesthesia was 860.5 (577.5, 1 180.0) seconds in the trail group and 676.0 (280.0, 1 401.0) seconds in the control group, with no statistically significant difference between the two groups ( Z=0.898, P>0.05). The incidence of adverse events in the trail group and control group were 5.45% (6/110) and 4.55% (5/110), respectively, without statistical significance between them ( P=1.000). Conclusions:The 3.5% lidocaine hydrochloride is a safe, effective, easy to use and high-quality surface anesthesia drug for eye surgery.
