Abstract
BACKGROUND To elucidate the role of Mucin1 (MUC1) in the trophoblast function (glucose uptake and apoptosis) of gestational diabetes mellitus (GDM) women through the Wnt/β-catenin pathway. METHODS Glucose uptake was analyzed by plasma GLUT1 and GLUT4 levels with ELISA and measured by the expression of GLUT4 and INSR with immunofluorescence and Western blotting. Apoptosis was measured by the expression of Bcl-2 and Caspase3 by Western blotting and flow cytometry. Wnt/β-catenin signaling measured by Western blotting. In vitro studies were performed using HTR-8/SVneo cells that were cultured and treated with high glucose (HG), sh-MUC1 and FH535 (inhibitor of Wnt/β-catenin signaling). RESULTS MUC1 was highly expressed in the placental trophoblasts of GDM, and the Wnt/β-catenin pathway was activated, along with dysfunction of glucose uptake and apoptosis. MUC1 knockdown resulted in increased invasiveness and decreased apoptosis in trophoblast cells. The initial linkage between MUC1, the Wnt/β-catenin pathway, and glucose uptake was confirmed by using an HG-exposed HTR-8/SVneo cell model with MUC1 knockdown. MUC1 knockdown inhibited the Wnt/β-catenin signaling pathway and reversed glucose uptake dysfunction and apoptosis in HG-induced HTR-8/SVneo cells. Meanwhile, inhibition of Wnt/β-catenin signaling could also reverse the dysfunction of glucose uptake and apoptosis. CONCLUSIONS In summary, the increased level of MUC1 in GDM could abnormally activate the Wnt/β-catenin signaling pathway, leading to trophoblast dysfunction, which may impair glucose uptake and induce apoptosis in placental tissues of GDM women.

Abstract
INTRODUCTION The management of women with clinical early-stage cervical cancer and lymph node involvement detected intraoperatively is heterogeneous and controversial. This paper presents the protocol of a systematic review and meta-analysis regarding the management of this specific population of patients. This proposed study aims to answer the question: does completion of radical hysterectomy improve the oncological outcomes of women with clinical early-stage cervical cancer and intraoperatively detected nodal involvement? METHODS AND ANALYSIS This protocol is drafted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols guidelines, and the proposed study will be conducted in accordance with the standard guidelines of 'Preferred Reporting Items for Systematic Reviews and Meta-Analyses' and 'Meta-analysis of Observational Studies in Epidemiology reporting guideline'. Comprehensive literature searches will be performed in PubMed, Embase, Scopus, and Web of Science. The screening of the eligible studies, the extraction of data of interest, and the quality assessment of the included studies will all be independently performed by different members of our team. The primary outcome of this proposed study will be comparing the risk of recurrence or death from cervical cancer and the risk of all-cause death in patients with two different treatments (completion of radical hysterectomy or abandonment of radical hysterectomy); the secondary outcome of this proposed study will be comparing the risk of the grade 3/4 toxicities associated with the two types of management. Given the clinical heterogeneity among the included studies, data on outcomes will be pooled by random-effects models. Heterogeneity will be evaluated using the I2 statistic. The risk of bias for the included studies will be evaluated using the Newcastle-Ottawa Scale or the Cochrane collaboration's tool. The grade of evidence will be evaluated by two independent members of our team using the Grading of Recommendations, Assessment, Development and Evaluations approach. ETHICS AND DISSEMINATION Ethical approval is not required because there will no primary data collected. The findings of this proposed study will be published in an international peer-reviewed journal. PROSPERO REGISTRATION NUMBER CRD42021273527.

Abstract
OBJECTIVES Previous studies examining the incidence of omental metastasis in uterine serous carcinoma generally suffered from the small sample size, retrospective observational design, and single-center setting. So far, there was no systematic review and meta-analysis available on this topic, we conducted this study to quantitatively synthesize the data relating to this topic. DESIGN systematic review and meta-analysis. MATERIAL AND METHODS PubMed, Embase, and Web of Science were searched up until August 15, 2020. Two reviewers independently performed study selection, data extraction, and quality assessment. I2 was employed to assess the heterogeneity among included studies. Effect sizes along with 95% confidence intervals were calculated to analyze outcomes of interest. Funnel plots and the Egger test were used to detect the possibility of publication bias. OUTCOME MEASURES incidence of omental metastasis in uterine serous carcinoma. RESULTS A total of 16 studies involving 1012 women with uterine serous carcinoma were included in this systematic review and meta-analysis. All the included studies were at low risk of bias, and the heterogeneity among them was low. The pooled incidence of overall omental metastasis, occult omental metastasis, and gross omental metastasis in uterine serous carcinoma were 18% (95% CI, 0.15-0.20), 6% (95% CI, 0.04-0.08), and 10% (95% CI, 0.08-0.13), respectively. CONCLUSIONS Uterine serous carcinoma has a high tendency of omental metastasis. The main form of omentum involvement is gross metastasis. However, occult metastasis in the normal-looking omentum is also worthy of note.

Abstract
Allyl alcohol is an intermediate widely used in industrial production activities, which has caused many occupational damage in China. In this paper, the data of a case of skin damage and clinical cure of inhalation pneumonia caused by occupational allyl alcohol exposure were analyzed and summarized. The patient accidentally inhaled large amounts of allyl alcohol at work and had skin exposure, which was mainly manifested as aspiration pneumonia, respiratory failure, eye damage and skin bullae. After short-term hormone shock therapy, mechanical ventilation, infection prevention, local treatment and other comprehensive treatment, the patient was clinically cured. This case suggests that chemical pneumonia and respiratory failure may be caused by inhalation of allyl alcohol, and skin bullae may be caused by skin contact. Early treatment and hormone use should be emphasized.

Abstract
This article investigated an occupational chronic benzene poisoning incident that occurred in a sealing material factory in Hebei Province in September 2019, analyzed the clinical data of workers, to explore the causes of occupational chronic benzene poisoning, and summarize the diagnosis and treatment characteristics and treatment outcome. According to GBZ 68-2013 "Diagnosis of Occupational Benzene Poisoning", a total of 12 cases of occupational chronic benzene poisoning were diagnosed among the 20 workers, including 2 cases of occupational chronic mild benzene poisoning, 7 cases of moderate benzene poisoning, and 3 cases of severe benzene poisoning. Both mild and moderate poisoning patients had recovered after treatment. Severely poisoned patients had recovered more slowly, and the white blood cell count was still 2.0×10(9)-3.0×10(9)/L during the 1-year follow-up. This benzene poisoning incident was caused by illegal operations. The responsibility of the employer, the supervision of the administrative agency, and the awareness of personal protection of employees should be strengthened to avoid or reduce the occurrence of poisoning incidents and ensure the health of workers.

Abstract
RATIONALE Salvianolic acid B (Sal B), the Q-marker in Salvia miltiorrhiza, was proved to present an obvious anti-diabetes effect when treated as a food intake. Until now, the metabolism feature, tissue distribution and anti-diabetes mechanism of Sal B have not been fully elucidated. METHODS The metabolites of Sal B in rats were profiled using ultrahigh-performance liquid chromatography coupled with time-of-flight mass spectrometry. The potential anti-diabetes mechanism of Sal B was predicted by network pharmacology. RESULTS A total of 31 metabolites were characterized in rats after ingestion of Sal B at a dosage of 40 mg/kg, including 1 in plasma, 19 in urine, 31 in feces, 0 in heart, 0 in liver, 0 in spleen, 1 in lung, 1 in kidney and 0 in brain. Among them, 18 metabolites were reported for the first time. Phase I reactions of hydrolysis, hydrogenation, dehydroxylation, hydroxylation, decarboxylation and isomerization, and phase II reactions of methylation were found in Sal B. Notably, decarboxylation and dehydroxylation were revealed in Sal B for the first time. The pharmacology network results showed that Sal B and its metabolites could regulate ALB, PLG, ACE, CASP3, MMP9, MMP2, MTOR, etc. The above targets were involved in insulin signaling pathway, PI3K-Akt signaling pathway, HIF-1 signaling pathway, TNF signaling pathway, etc. CONCLUSIONS: The metabolism feature of Sal B in vivo was systematically revealed, and its anti-diabetes mechanism for further pharmacological validations was predicted based on metabolite profiling and network pharmacology for the first time.

Abstract
Medoggreenpit-viper bites are extremely rare in northern China. This article analyzed the clinical data, laboratory test results, treatment methods and the outcome of a case of poisoning from the Medoggreenpit-viper snake bite in the northern area. The main clinical manifestations of the patient were local swelling and bleeding. The wound was debrided immediately after the patient was admitted to the hospital, and vacuum suction was given after the debridement. After been treated with anti-Agkistrodon venom serum, anti-Gyrus serpent, anti-infection, organ protection, fluid replacement and diuresis, the patient recovered and was discharged from the hospital. The patients were generally in good condition after follow-up. This case suggested that regional poisoning treatment centers in the northern region should stock various anti-venom serums. At the same time, it is necessary to popularize knowledge of standard treatment of snake bites.

Abstract
RATIONALE Characterizing the functional mechanism of quality control marker (Q-marker) was of great importance in revealing the primary pharmacological mechanism of herbs or the other complex system, and drug-related metabolites always contribute to the pharmacological functions. Cortex Phellodendri was used as a core herb in the treatment of diabetes mellitus (DM). As a Q-marker of Cortex Phellodendri, the role of phellodendrine in DM was still unclear. Thus, the characterization of phellodendrine-related metabolites in vivo and the subsequent induced functional mechanism exerted great importance in elucidating the anti-DM mechanism of Cortex Phellodendri. METHODS An ultra-high-performance liquid chromatography-coupled time-of-flight mass spectrometry (UHPLC/Q-TOF MS) method was developed to profile metabolites of phellodendrine in rats. The potential pharmacological mechanism against DM was predicted by network pharmacology. RESULTS A total of 19 phellodendrine-related metabolites were screened out in rats for the first time. Among them, M4, M5, M9, and M12 were regarded as the primary metabolites. Meanwhile, phase I metabolic reactions of hydroxylation, demethylation, and isomerization and phase II reactions of glucuronidation and sulfation occurred to phellodendrine; glucuronidation and hydroxylation were the two main metabolic reactions. Moreover, the potential targets of phellodendrine and three main metabolites (M4, M5, and M12) were predicted by a network pharmacological method, and they mainly shared 52 targets, including PDE5A, CHRNA3, SIGMAR1, F3, ESR1, DRD1, DRD2, DRD3, and DRD4. Furthermore, Kyoto Encyclopedia of Genes and Genomes pathway analysis showed that calcium signaling pathway, cGMP-PKG signaling pathway, and cAMP signaling pathway were regarded as the core mechanism of phellodendrine to treat DM. CONCLUSION The metabolic feature of phellodendrine in vivo was revealed for the first time, and its anti-DM mechanism information for further pharmacological validations was also supplied. It also gave a direction to further elucidation of pharmacological mechanism of Cortex Phellodendri in treating DM.

Abstract
The C(sp3)-H functionalization of O-pentafluorobenzoyl ketone oximes was implemented under visible light irradiation with copper complexes as catalysts. The reactions involve iminyl-radical-mediated intramolecular hydrogen atom transfer as the key step, with the iminyl radicals being generated via copper-effected N-O cleavage. The reaction afforded 3,4-dihydro-2H-pyrroles under the conditions of [Cu(DPEphos)(bcp)]PF6 and DABCO, while γ-pentafluorobenzoyloxy ketones were produced predominantly when [Cu(dpp)2]PF6 and InCl3·4H2O were used as catalysts.

Abstract
Food additives are widely used in our daily life, and the side-effects caused by them have gained extensive attention around the world. Notably, constituent-oriented metabolites, in some sense, always contribute to pharmacological changes, inducing toxicity, therapeutic effects, etc. Characterization of the metabolites and their potential functions is of great importance to the practical applications. In this work, an integrated strategy by combining metabolite profiling and network pharmacology was applied to characterize the metabolic features and reveal pharmacological changes of neohesperidin dihydrochalcone (NHDC) in vivo to demonstrate its pharmacological mechanism and potential functions. As a result, a total of 19 metabolites (3 in plasma, 19 in urine, 8 in feces, 3 in heart, 5 in liver, 0 in spleen, 1 in lung, 2 in kidneys and 2 in brain) were screened and 18 of them were characterized for the first time. Phase I metabolic reactions of hydrolysis and phase II reactions of glucuronidation, sulfation, glutamylation, N-butyryl glycylation and lactylation were the main metabolic reactions of NHDC in vivo. Moreover, the results analyzed by network pharmacology revealed that, in addition to common pathways (steroid hormone biosynthesis) of NHDC, metabolites' targets were involved in pathways in cancer, ovarian steroidogenesis, proteoglycans in cancer, PI3K-Akt signaling pathway and progesterone-mediated oocyte maturation, indicating that these functional changes might result in potential novel functions or other side-effects, such as a disorder of steroid hormones. Our work provided the metabolic features and functional modifications of NHDC in vivo for the first time, and meaningful information for further pharmacological validations or potential functions is supplied.

Abstract
Lonicerae japonicae flos.(LJF) was widely used as a drug to treat upper respiratory tract infection or a tea to clear heat in Asian countries for thousands of years. Despite of its curative effects confirmed by modern pharmacological methods, its functional materials and mechanism against influenza were still unclear and needed further investigation. In this study, an integrated strategy based on in vivo substances profiling and network pharmacology was proposed and applied to screen out the potential anti-influenza substances and mechanism of LJF. An UHPLC/Q-TOF MS method was utilized to profile the chemical components in LJF and their metabolites in rats. The targets of absorbed prototypes were predicted by Swiss Target Prediction, and they were further analyzed by String and Kyoto Encyclopedia of Genes and Genomes (KEGG). As a result, a total of 126 chemical components mainly featuring three chemical structure types were characterized, including 70 iridoid glycosides, 17 caffeoylquinic acids, 24 flavonoids, and 15 other types compounds. Among them, ten N-contained iridoid glycosides were characterized as potential novel compounds. Moreover, 141 xenobiotics (74 prototypes and 67 metabolites) were clearly screened out in rat plasma and urine after ingestion of LJF. Phase II reactions (sulfation, glucuronidation, methylation) and phase I reactions (dehydroxylation, hydrogenation, hydrolysis, N-heterocyclization) were the main metabolic reactions of LJF in rats. Further, a total of 338 targets were predicted and TNF, PTGS2 and EGFR were the three main targets involved in the pathology of influenza. In addition to normal NF-κB pathway, T cell signal pathway and mTOR signal pathway were the other patterns for LJF to achieve its anti-flu effects. Our work provided the meaningful data for further pharmacological validation of LJF against influenza, and a new strategy was also proposed for minimizing the process to reveal the mechanism and functional basis of TCMs.

Abstract
Traditional Chinese medicine was widely used in China since its definite effects and therapy. The components of TCM were absorbed into the circle system as the format of prototypes or metabolites, which contributed to the therapy or side effects. Declaring the functional changes in this process was of great importance to the clinical applications. In this work, an integrated strategy based on metabolites' profiling and network pharmacology was proposed for exploring the pharmacological changes of compounds in vivo. Arctiin, the main component in Fructus Arctii with various kinds of bioactivities, was used as an example. An ultra-performance liquid chromatography coupled with time-of-flight mass spectrometry and metabolynx™software was applied to characterize the metabolites of arctiin in rats at a dosage of 100 mg/kg; network pharmacology was applied to characterize the functional changes. As a result, fifty-three metabolites (32 in plasma, 40 in urine, 19 in bile, 20 in feces, 1 in brain, 12 in liver and 4 in lungs) were screened out and characterized, and 3 of them were unambitiously identified by comparison with standard substances. Among them, 38 metabolites were reported for the first time. It was found the major metabolic pathways of arctiin in rats were demethylation, lactone-opening and phase II conjugations with sulfate and glucuronide.It also confirmed that M14, M15, M18, M23, M22, M43 and M45 were the major circulating forms of arctiin in rats following oral administration. In addition to the above metabolic reactions, phase I reactions of hydrolysis, demethylation, dehydroxylation were also observed, and dehydrogenation were first revealed metabolic patterns of arctiin in rats. Meanwhile, in addition to the main targets of arctiin (MTOR, EGFR and MAPK14), its metabolites targeted additional 392 targets with additional functions of anti-hepatitis B or viral carcinogenesis (SRC, CAPS3, PIK3CA, CDK4, ESR1, MMP9 and ERBB2). The above results provided very important information for understanding the metabolism and functional changes of arctiinin vivo, and supporting data for further pharmacological evaluation. Our work also provided a newsight for elucidation of functional changes of TCMs in vivo.

Abstract
Objective To investigate the biomechanical effects of reduction quality on patients after femoral neck fracture internal fixation. Methods The data of individual patients with femoral neck fractures were reviewed. Data for patients with simple unilateral femoral neck fractures whose reduction quality was evaluated as good by hip X‐ray films after internal fixation were collected from January 2013 to January 2017. The CT data of the patients was used to reconstruct 3D models of the femur and the screw. The spatial displacement after the operation of femoral neck fracture was measured, which included the displacement of the deepest portion of the femoral head fovea, the displacement of the center of the femoral head, and the rotational angle. The cases were followed up by telephone consultation and clinical review to determine whether the osteonecrosis of the femoral head occurred. Follow‐up time should be more than 18 months after surgery. The cases were grouped according to the results into an osteonecrosis of the femoral head group and a non‐osteonecrosis of the femoral head group. Finally, the differences in postoperative spatial displacement between the two groups were compared and analyzed. In addition, a mechanical analysis of femoral force during gait was performed via finite element analysis. Results Data for 241 patients with femoral neck fractures who were treated with closed reduction and internal fixation were collected. 3D measurement showed the average displacement value, including the center of the femoral head (5.90 ± 3.4 mm), the deepest portion of the femoral head fovea (9.32 ± 4.8 mm), and the rotational angle (16.1° ± 9.4°). After telephone consultation and clinical review, osteonecrosis of the femoral head was diagnosed in 28 (11.62%) of the patients. In the osteonecrosis of the femoral head (ONFH) group, the displacement of the deepest portion of the femoral head fovea was 10.92 ± 9.18 mm; the displacement was 8.86 ± 6.29 mm in the non‐ONFH group. The displacement of the center of the femoral head in the ONFH group was 7.575 ± 5.69 mm and 5.31 ± 4.05 mm in non‐ONFH group. The rotational angle was 20.11° ± 10.27° in the ONFH group and 14.19° ± 11.09° in the non‐ONFH group. The statistical analysis showed that the postoperative spatial displacements, including the displacement of the deepest portion of the femoral head fovea, the displacement of the center of the femoral head, and the rotational angle between the two groups, had statistical differences. Finite element analysis showed that as the spatial displacement increased, the stress, the displacement, and the equivalent strain of the proximal femur also increased. Conclusion Poor reduction quality after femoral neck fracture is a risk factor for re‐fracture and femoral head necrosis, and the measurement method of this study can be used to predict the occurrence of femoral head necrosis early after femoral neck fracture.

Abstract
The prototypes and metabolites formed from the use of traditional Chinese medicines (TCM) are typically the cause of both side side-effects and therapeutic results. Therefore, the characterization of in vivo substances and the determination of functional changes are of great importance for clinical applications. Secoisolariciresinol-diglycoside (SDG), one major compound in flaxseeds, was used as a potential drug to treat tumors in the clinic; however, the metabolism information and functional changes of SDG in vivo were limited, which limited its application. In this study, an integrated strategy based on metabolite profiling and network pharmacology was applied to explore the metabolism feature and functional changes of SDG. As a result, a total of 28 metabolites were found in rats, including 14 in plasma, 22 in urine, 20 in feces, 7 in the heart, 14 in the liver, 8 in the spleen, 10 in the lungs, 14 in the kidneys, and 4 in the brain. Among them, M8, M13 and M26 were the main metabolites of SDG in rats and 24 were characterized for the first time. The metabolic reactions contained phase I reactions of demethylation, dehydroxylation, deglycosylation, arabinosylation and glycosylation, and phase II reactions of glucuronidation and sulfation were also observed. Notably, the arabinosylation and glycosylation were found in SDG for the first time. Meanwhile, 121 targets of SDG and its metabolites were found, PRKCB was the main target of SDG, and the metabolites of SDG mainly targeted HSP90A1, IL6, AKT1, MAPK3, MTOR, PIK3CA, SRC, ESR1, AR, PIK3CB, and PIK3CB. The difference of targets between SDG and its metabolites could result in its additional functional pathways of neurotrophin signaling pathway, PI3K-Akt signaling pathway, HIF-1 signaling pathway or indications of anti-prostate cancer. This work provided a new insight for exploring the mechanism and therapy indications of drugs. The prototypes and metabolites formed from the use of traditional Chinese medicines (TCM) are typically the cause of both side side-effects and therapeutic results.![]()

Abstract
Objective: To investigate the clinicopathological characteristics and significance of solid, endometrioid and transitional (SET) ovarian high-grade serous carcinoma (HGSC). Methods: A total of 408 cases of ovarian HGSC admitted to Peking University People's Hospital from January 2011 to September 2016 were collected. (1) According to the proportion of tumors with SET form in all tumors, they were divided into three groups: HGSC-classic group (<25%), HGSC-SET Ⅰ (25%-50%) and HGSC-SET Ⅱ (>50%) group. The clinical and pathological characteristics of three groups of ovarian HGSC patients were compared respectively. (2) According to the growth pattern, that was, the proportion of pushing/expanding invasive tumors in the whole pelvic disseminated tumors of pelvic disseminated tumors, the three groups were divided into four subgroups: group A (0-25%), group B (26%-50%), group C (51%-75%) and group D (>75%). Differences in progression-free survival (PFS) among the four subgroups in each group were compared respectively. Results: The median age of 408 cases with ovarian HGSC was 63.3 years (47-78 years), including 152 cases premenopausal and 256 cases postmenopausal. Among 408 cases of ovarian HGSC, 290 cases were in HGSC-classic group, 91 cases in HGSC-SET Ⅰ and 27 cases in HGSC-SET Ⅱ group. (1) There were significant differences in age, proportion of menopausal patients, tumor necrosis (including map necrosis or acne necrosis), response rate to primary chemotherapy, 5-year mortality rate and PFS between HGSC-SET Ⅰ and HGSC-SET Ⅱ (P<0.05). There was no significant difference among the above indexes between HGSC-SET Ⅰ and HGSC-SET Ⅱ (P>0.05). In HGSC-classic group, HGSC-SET Ⅰ and HGSC-SET Ⅱ, the proportion of family members or patients with history of epithelial ovarian cancer or breast cancer increased in turn, and the detection rate of serous tutal intraepithelial carcinoma (STIC) in fallopian tube tissue decreased in turn. There were significant differences between the two groups (P<0.05). (2) In HGSC-classic group, there were 147 cases in group A, 124 cases in group B and 19 cases in group C (0 case in group D), with median PFS of 17.4, 17.7 and 16.5 months respectively (P<0.05); 10, 6, 29 and 46 cases in group A, B, C and D in HGSC-SET Ⅰ, with median PFS of 9.6, 12.7, 30.1 months and 39.0 months respectively, which there were significant difference among group A and C and D (all P<0.05); among group B, C and D group in HGSC-SET Ⅱ, there were respectively 3, 12 and 12 cases (0 case in group A), and the median PFS was 13.5, 34.2 and 47.8 months (P<0.05). PFS was positively correlated with the increase of push/expansive infiltration ratio. Conclusions: The detection rate of STIC in ovarian HGSC patients with SET is higher, the effect of primary chemotherapy is better, and PFS is prolonged. PFS was significantly prolonged in patients with pelvic disseminated tumors of HGSC-SET, the infiltration of which were predominated by pushing or expanding boarder.

Abstract
Objective: To assess the reading speed of normally-sighted young Chinese with the International Reading Speed Texts (IReST) Chinese version, and evaluate the normal range of the texts, the equivalence of the ten different texts and the potential clinical value. Methods: Evaluation of diagnostic techniques. Participants aged 18 to 35 years old with junior high school or above education and best corrected visual acuity no less than 0.6 were recruited. Best corrected visions of both eyes and binocular vision were tested, and ocular and nervous system diseases were excluded with slit-lamp microscope and funduscope. All the ten texts were read aloud at a distance of 40cm one by one according to a random sequence for each participant. Reading speeds were calculated based on the reading time measured with a stopwatch and number of characters read correctly. The procedure was repeated once again a week later. Data were collected with Epidata and further analyzed with R software. Data accorded with normal distribution and homogeneity of variance were compared by t-test, or by rank sum test. Results: One hundred and three volunteers aged (26.0±2.8) years old participated in the survey. Among them, 66% were female, 96.1% had college education, 53.4% wear glasses in daily life. The best corrected vision of both distance and near were 1.0 (decimal). For the first test, average reading speed for all the participants and texts was (295±51) characters/min,much faster than the normal range provided by the reading cards. No significant difference was found between different texts, and the biggest variance between texts was 11 characters/min(P>0.05). The average reading speed of the second test was (315±53) characters/min, which was faster than the first one (P<0.05) . No statistic relationship was found between reading speed and age, education level or wearing of glasses. However, women read faster than men, and significant difference was found between male and female volunteers in 5 texts during the first test. Conclusions: Normally-sighted young Chinese readers read faster than the normal range provided by IReST cards. There is significant variance of reading speed between different individuals. Although learning effect due to the repeated tests should be considered, the ten texts are of favorable consistency. IReST can be a useful tool for assessing reading performance, especially for comparing results before and after interventions with different texts. (Chin J Ophthalmol, 2018, 54: 120-124).

Abstract
To understand the adaptive strategies of the overwintering adults of Stenocatantops splendens, the mechanism of maintenance and termination of the reproductive diapause, the variation in mortality between overwintering females and males, and the mating strategy of the males were investigated. The results indicated that the adult reproductive diapause in natural conditions was mainly regulated by photoperiod in the fall - long photoperiods promoted reproductive development and short photoperiods maintained reproductive diapause, and the sensitivity of the overwintering adults to photoperiod was over before the end of the winter. When transferred from natural conditions to controlled laboratory conditions on dates from September through February, pre-oviposition became increasingly shorter with increasingly deferred transfer dates regardless of photoperiod conditions. The adults treated with low temperature for 30 days in September through November had significantly shorter pre-oviposition, suggesting that low temperatures in winter had an important role in the termination of reproductive diapause. The female had a significantly lower supercooling point than the male, which was related to their lower mortality after winter. In addition, observations of wild populations of the species indicated that mating behavior prior to winter and the duration of pre-mating period were not affected by photoperiod; mating and sperm transfer were mostly completed by November. Compared with females only mating before winter, females mating in the spring had shorter life span, longer pre-oviposition, lower hatching rate and laid fewer egg pods while showing no significant difference with regard to ovipositional interval, per pod number of eggs and nymph dry weight.

Abstract
Cannabis (i.e., marijuana and cannabinoids) is the most commonly used illicit drug in developed countries, and the lifetime prevalence of marijuana dependence is the highest of all illicit drugs in the United States. To provide clues for finding effective pharmacological treatment for cannabis-dependent patients, we examined the effects and possible mechanism of lithium administration on the cannabinoid withdrawal syndrome in rats. A systemic injection of the mood stabilizer lithium, at serum levels that were clinically relevant, prevented the cannabinoid withdrawal syndrome. The effects of lithium were accompanied by expression of the cellular activation marker Fos proteins within most oxytocin-immunoreactive neurons and a significant increase in oxytocin mRNA expression in the hypothalamic paraventricular and supraoptic nuclei. Lithium also produced a significant elevation of oxytocin levels in the peripheral blood. We suggest that the effects of lithium against the cannabinoid withdrawal syndrome are mediated by oxytocinergic neuronal activation and subsequent release and action of oxytocin within the CNS. In support of our hypothesis, we found that the effects of lithium against the cannabinoid withdrawal syndrome were antagonized by systemic preapplication of an oxytocin antagonist and mimicked by systemic or intracerebroventricular injection of oxytocin. These results demonstrate that oxytocinergic neuronal activation plays a critical role in the action of lithium against the cannabinoid withdrawal syndrome in rats, thus providing a potentially novel strategy for the treatment of cannabis dependence in humans.
