Intermittent exotropia(IXT)is the most prevalent form of childhood strabismus, with an estimated prevalence of approximately 3.26% in the Chinese population. Although patients can intermittently maintain orthotropia, the deviation angle often fluctuates markedly, and frank exotropia may become evident during fatigue or lapses in attention. Without intervention, roughly 75% of cases progress over time. Management comprises surgical and non-surgical approaches. Surgery remains the most definitive treatment, however, the optimal timing is controversial, and postoperative outcomes may include under- or over-correction, necessitating additional procedures. Non-surgical options include observation, refractive correction, over-minus lens therapy, prisms, orthoptic exercises, and botulinum toxin-A injections. These modalities are particularly suitable for young, or uncooperative children, patients with small-angle, well-controlled deviations, or those seeking to defer surgery, in such cases, non-surgical treatment can maintain binocular alignment and preserve monocular function, thereby delaying or avoiding surgery. Because the efficacy of each non-surgical strategy varies, this review summarizes the current evidence on non-surgical treatment of IXT.

[Objective] To assess the data characteristics of quality monitoring indicators for red blood cell (RBC) preparations, so as to provide reference for continuous improvement of blood quality. [Methods] The quality inspection data of 6 types of RBC preparations from Chongqing blood center from 2019 to 2023 were summarized. For the same indicators, the numerical range of quality indicators was monitored by comparing different types of preparations with the national standard GB18469. The loss and/or damage to RBCs caused by different preparation process were compared, and the impact of different preparation processes on the quality of RBCs was discussed. [Results] The appearance and sterility test compliance rates of the six types of RBC preparations were both 100%, while the compliance rates of other items were all ≥75%. The compliance rate of hematocrit for suspended RBCs was the lowest at 75%, with a median of 0.52, which was close to the lower limit of GB18469, while the medians of hematocrit for the other types were all at the midline level of GB18469. The Hb content for different types of RBCs was significantly higher than the corresponding requirements of GB18469 (P<0.05). The hemolysis rate at the end of storage for different types of RBCs was significantly lower than the requirements of GB18469 (P<0.05). The 1 U leukoreduction process resulted in a hemoglobin content loss of about 5% and had a significant impact on the hemolysis rate at the end of storage (P<0.05). The washing process resulted in a hemoglobin content loss of <3% and had no significant impact on the hemolysis rate at the end of storage (P>0.05). The concentration process resulted in a hemoglobin content loss of <3% and had a significant impact on the hemolysis rate at the end of storage (P<0.05). [Conclusion] The impact of different processes on RBC preparations is within a controllable range and meets the requirements of GB18469. The quality monitoring data can provide a reference for clinical blood selection, effectiveness evaluation and revision of related standards.

OBJECTIVE To analyze the factors influencing patient satisfaction in the outpatient pharmacy of tertiary maternity and child specialist hospitals in Chongqing， and provide a reference for improving the pharmaceutical management capability of tertiary maternity and child specialist hospitals and enhancing patients’ medical experience. METHODS Utilizing KANO model， a questionnaire was developed and data were analyzed. Key influencing factors were identified through the categorization of requirement attributes， Better values， Worse values， and two-dimensional matrix analysis. The impact of these categorized demand factors on overall satisfaction was further validated through Structural Equation Modeling （SEM）. RESULTS Cronbach’s α coefficient for the survey questionnaire was 0.855， exceeding the acceptable threshold of 0.7； Bartlett test for sphericality yielded a value of 5 538.56 with P＜0.01， indicating good reliability and validity of the survey results. Through the KANO model’s factor selection process， the top four key factors influencing patient satisfaction in outpatient pharmacies were determined to be： medication pick-up time （r＝0.45）， pharmacist service attitude （r＝0.45）， rational medication consultation （r＝0.41）， self-service calling system （r＝0.40）， all of which were subsequently validated through SEM. CONCLUSIONS The four factors of medication pick-up time， self-service calling system， pharmacist service attitude， and rational medication consultation significantly influence patient satisfaction in the outpatient pharmacies of tertiary maternity and child hospitals in Chongqing.

ObjectiveBased on the adenosine 5'-monophosphate （AMP）-activated protein kinase/protein kinase B/nuclear factor erythroid 2-related factor 2 （AMPK/Akt/Nrf2） pathway， this study aims to explore the mechanism by which modified Guishenwan improves glucose and lipid metabolism and oxidative stress in polycystic ovary syndrome （PCOS） rats. MethodsA PCOS rat model was established by continuous oral administration of letrozole （1 mg·kg^-1·d^-1） for 21 days. Successfully modeled rats were randomly divided into a model group， a metformin group （0.25 g·kg^-1）， and low-， medium-， and high-dose modified Guishenwan groups （4.01， 8.02， and 16.04 g·kg^-1·d^-1）， with 8 rats in each group. Ten normal rats were assigned to the normal group. The drug groups were given their respective doses， while the normal and model groups were given an equal volume of normal saline. Intervention lasted for 4 weeks. Testosterone （T）， estradiol （E₂）， follicle-stimulating hormone （FSH）， and luteinizing hormone （LH） were measured by enzyme-linked immunosorbent assay （ELISA）， and the LH/FSH ratio was calculated. Fasting blood glucose （FPG）， fasting insulin （FINS）， triglyceride （TG）， and total cholesterol （TC） levels were measured using an automatic biochemical analyzer， and the insulin resistance index （HOMA-IR） and insulin sensitivity index （HOMA-ISI） were calculated. Oral glucose tolerance test （OGTT） and insulin tolerance test （ITT） were conducted. Malondialdehyde （MDA）， advanced glycation end products （AGEs）， and superoxide dismutase （SOD） levels in serum and ovarian tissue were measured using a chemical fluorescence method. Hematoxylin-eosin （HE） staining was used to assess ovarian tissue pathology. Real-time quantitative fluorescent polymerase chain reaction （Real-time PCR） and Western blot were used to measure the expression of AMPK/Akt/Nrf2 pathway-related genes and proteins in ovarian tissue. ResultsCompared with the normal group， the model group exhibited significantly increased levels of T， LH， LH/FSH， FPG， FINS， TG， TC， and HOMA-IR， while FSH， E₂， and HOMA-ISI were significantly decreased （P<0.05， P<0.01）. MDA and AGEs levels were significantly higher in both serum and ovarian tissue， and SOD levels were significantly reduced （P<0.05）. AMPK， Akt， and Nrf2 mRNA and protein expression in ovarian tissue was also significantly reduced （P<0.05）. The OGTT and ITT results showed significantly higher blood glucose levels at each time point （P<0.05， P<0.01）， with impaired glucose and insulin tolerance. Ovarian follicles showed polycystic changes， reduced corpus luteum， and sparse granulosa cell layers. Compared with the model group， the metformin group and the high-dose modified Guishenwan group showed significant decreases in T， LH， LH/FSH， FPG， FINS， TG， TC， and HOMA-IR， while FSH， E₂， and HOMA-ISI were significantly increased （P<0.05， P<0.01）. In the high-dose modified Guishenwan group， MDA and AGEs levels in serum and ovarian tissue were significantly reduced， and SOD levels were significantly increased （P<0.05）. The mRNA and protein expression of AMPK， Akt， and Nrf2 in ovarian tissue was significantly increased （P<0.05）. OGTT and ITT results showed that blood glucose levels in rats decreased significantly at each time point （P<0.05， P<0.01）. No obvious abnormalities were observed in ovarian tissue. Compared with the low-dose modified Guishenwan group， the high-dose group showed significant decreases in T， LH， LH/FSH， FPG， FINS， TG， TC， and HOMA-IR， while FSH， E₂， and HOMA-ISI were significantly increased （P<0.05）. OGTT and ITT results indicated that the high-dose modified Guishenwan group significantly improved glucose and insulin tolerance in rats. No significant abnormalities were observed in ovarian tissue. ConclusionModified Guishenwan effectively improves glucose and lipid metabolism abnormalities and inhibits oxidative stress in PCOS rats， potentially through regulation of the AMPK/Akt/Nrf2 pathway.

BackgroundFamily factors are known to play a critical role in the development， progression and prognosis of adolescent patients with depressive disorder. Psychodrama group therapy has the potential for bringing about positive change in individual growth and relationship repair， but there is currently insufficient research evidence for the effectiveness of psychodrama group therapy in promoting the recovery in depressive disorder in adolescents through improving the family parenting skills of their parents. ObjectiveTo explore the influence of psychodrama group therapy based on family parenting intervention on parents of adolescent patients with depressive disorder， so as to provide references for promoting the recovery for adolescent patients with depressive disorder. MethodsPurposive sampling was used to recruit adolescent patients who met the diagnostic criteria for depressive disorder of the International Classification of Diseases， tenth edition （ICD-10） and hospitalized in the psychiatric outpatient department of the First Affiliated Hospital of Chongqing Medical University from October 2023 to March 2024， and their parents （either mother or father） were taken as the study subjects. Psychodrama group therapy based on family parenting intervention was performed once a week for 6 consecutive weeks. After intervention， semi-structured interviews were conducted with parents who participated in the group， and the interviews were recorded. Content analysis method was employed to perform qualitative analysis on the interview recordings and verbatim transcripts. ResultsAfter receiving psychodrama group intervention based on family parenting， parents of adolescent patients with depressive disorder demonstrated improvement in emotional state， enhanced reflective ability and altered coping style， which were specifically manifested as reducing negative emotions， increasing positive emotions， reflecting on themselves， empathizing with others， adjusting cognition， changing the way of stress regulation， improving communication styles and actively seeking resources. ConclusionApplication of psychodrama group therapy based on family parenting intervention may improve emotional state， reflective ability and coping style of the parents of adolescent patients with depressive disorder. ［Funded by Chongqing Education Commission Humanities and Social Science Research Project （number， 19SKGH018）； Chongqing Social Science Planning Project （number， 2021WT29）］

Epidermal growth factor receptor-tyrosine kinase inhibitor （EGFR-TKI） represent a class of small-molecule targeted therapeutics for oncology treatment， and serve as first-line therapy for advanced non-small cell lung cancer （NSCLC） with EGFR- sensitive mutations， with representative agents including gefitinib， dacomitinib， and osimertinib. In clinical practice， dose adjustment of EGFR-TKI may be required for cancer patients under special circumstances such as drug combinations or hepatic/ renal impairment. Physiologically-based pharmacokinetic （PBPK） model， capable of predicting pharmacokinetic （PK） processes in humans， has emerged as a vital tool for clinical dose optimization. This article sorts the modeling methodologies， workflows， and commonly used software tools for PBPK model， and summarizes the current applications of PBPK model in EGFR-TKI precision therapy as of June 30， 2024. Findings demonstrate that PBPK modeling methods commonly employ the “bottom-up” approach and the middle-out approach. The process typically involves four steps： parameter collection， compartment selection， model validation， and model application. Commonly used software for modeling includes Simcyp， GastroPlus， and open-source software such as PK- Sim. PBPK model can be utilized for predicting drug-drug interactions of EGFR-TKI co-administered with metabolic enzyme inducers or inhibitors， acid-suppressive drugs， or traditional Chinese and Western medicines. It can also adjust dosages in conjunction with genomics， predict PK processes in special populations （such as patients with liver or kidney dysfunction， pediatric patients）， evaluate the efficacy and safety of drugs， and extrapolate PK predictions from animal models to humans.

ObjectiveTo evaluate the effectiveness of stone needle thermocompression and massage compared to flurbiprofen gel patch in relieving chronic musculoskeletal pain in the shoulder and back， and to explore the potential mediating mechanism through muscle elasticity. MethodsA total of 120 patients with chronic musculoskeletal pain in the shoulder and back were randomly assigned to either stone needle group or flurbiprofen group， with 60 patients in each. The stone needle group received stone needle thermocompression and massage for 30 minutes， three times per week； the flurbiprofen group received flurbiprofen gel patch twice daily. Both groups were treated for 2 weeks. Pain improvement， as the primary outcome， was assessed using the Global Pain Scale （GPS） at baseline， after 2 weeks of treatment， and again 2 weeks post-treatment. To explore potential mechanisms， a mediator analysis was conducted by measuring changes in superficial and deep muscle elasticity using musculoskeletal ultrasound at baseline and after the 2-week treatment period. ResultsThe stone needle group showed significantly greater pain relief than the flurbiprofen group 2 weeks post-treatment. After adjusting for confounders related to pain duration， the between-group mean difference was -8.8 ［95% CI （-18.2， -0.7）， P＜0.05］. Part of the therapeutic effect was mediated by changes in deep muscle elasticity， with a mediation effect size of -1.5 ［95% CI （-2.0， -0.9）， P = 0.024］， accounting for 17.9% of the total effect. ConclusionStone needle thermocompression and massage can effectively relieve chronic musculoskeletal pain in the shoulder and back， partly through a mediating effect of improved deep muscle elasticity.

Objective: To explore the association of health literacy with overweight and obesity among middle school students in Chongqing, so as to provide evidence for obesity prevention and control strategies. Methods: From November to December 2019, a stratified cluster sampling method was used to select 7 851 middle school students from 8 complete middle schools across 4 districts/counties in Chongqing. Participants completed the Adolescent Health Literacy Questionnaire and underwent nutritional status assessments. Chisquare tests and multivariate Logistic regression analyses were performed to evaluate associations. Results: The prevalence of overweight and obesity among adolescents was 12.95%. The overall health literacy rate and rates for functional, interactive, and critical health literacy dimensions were 62.01%, 66.02%, 50.07%, and 72.42%, respectively. Significant differences in overweight and obesity prevalence were observed across districts/counties, urban/rural areas, sex, school stages, and onlychild status (χ2=25.93, 3.86, 80.55, 8.80, 6.43, P<0.05). After adjusting for confounding factors, multivariate Logistic regression revealed that middle school students with overall health literacy (OR=0.86, 95%CI=0.75-0.99), interactive health literacy (OR=0.85, 95%CI=0.74-0.97), and critical health literacy (OR=0.84, 95%CI=0.73-0.98) had a lower risk of overweight and obesity (P<0.05). Conclusions Health literacy is inversely associated with overweight and obesity among middle school students. Strengthening health education and improving interactive and critical health literacy may create favorable conditions for adolescent overweight and obesity prevention and control.

Transorbital craniocerebral injury is a relatively rare type of penetrating head injury that poses a significant threat to the ocular and cerebral structures.[1] The clinical prognosis of transorbital craniocerebral injury is closely related to the size, shape, speed, nature, and trajectory of the foreign object, as well as the incidence of central nervous system damage and secondary complications. The foreign objects reported to have caused these injuries are categorized into wooden items, metallic items,[2-8] and other materials, which penetrate the intracranial region via five major pathways, including the orbital roof (OR), superior orbital fissure (SOF), inferior orbital fissure (IOF), optic canal (OC), and sphenoid wing. Herein, we present eight cases of transorbital craniocerebral injury caused by an unusual metallic foreign body.

ObjectiveTo investigate the effects of Tongxinluo capsules on traditional Chinese medicine （TCM） syndrome elements and major adverse cardiovascular events （MACEs） in patients with chronic coronary syndrome of Qi deficiency and blood stasis type. MethodsA multicenter and prospective cohort study was conducted. The intervention of Tongxinluo Capsules was used as the exposure factor， and the patients were divided into an exposure group （integrated traditional Chinese and western medicine treatment group） and a non-exposure group （western medicine treatment group）. The patients were followed up for one year. The TCM syndrome element scores were assessed by using a syndrome element diagnosis scale on the day of enrollment and in the third， sixth， and twelfth months， and the incidence of MACE within one year was recorded. ResultsA total of 186 patients were included， with 128 patients in the exposure group and 58 patients in the non-exposure group. There was no significant difference in baseline data between the two groups. Compared with those in the pretreatment period for each group， the Qi deficiency and blood stasis syndrome scores in the treatment and follow-up period were significantly improved （P<0.05）. Compared with the non-exposure group， the exposure group exhibited significantly decreased Qi deficiency syndrome scores in the treatment and follow-up period （P<0.01） and significantly reduced blood stasis syndrome scores in the sixth month （P<0.05）. In the remaining follow-up period， there was no statistically significant difference between the two groups. Compared with that of the non-exposure group， during the treatment period （the third month）， the difference in Qi deficiency and blood stasis syndrome scores of the exposure group was statistically significant （P<0.05， P<0.01）. At the end of the follow-up period， patients in the non-exposure group had a MACE probability of 6.90% （4/58）， higher than 3.13% in the exposure group （4/58）. Compared with patients with angina pectoris who used conventional medicine， patients administered with Tongxinluo Capsules had a relative risk（RR） of 0.45 ［95%confidence interval（95%CI） 0.12-1.75， P=0.26］. There was no significant difference in the incidence of MACE within one year between the two groups. ConclusionTongxinluo capsules can improve the degree of Qi deficiency in patients with chronic coronary syndrome in the short term， and the improvement effect of blood stasis syndrome appears in the medium and long term. They can better improve the Qi deficiency syndrome in the long term. Within one year， the incidence of MACE in the exposure group was lower than that in the non-exposure group.
