AIM:To investigate the effects of electroacupuncture at the Taiyang on refractive parameters and the expression of β-catenin and integrin β1 in the ciliary body of mice with form-deprivation myopia(FDM).METHODS:A total of 48 3-week-old healthy C57BL/6J mice were randomly divided into 4 groups: normal control(NC), FDM group, sham acupuncture(sham), and electroacupuncture at Taiyang acupoint(Taiyang), with 12 mice in each group. Mice in the FDM, sham, and Taiyang groups, wore translucent custom-made eye masks on the right eye to induce myopia. The Taiyang group received electroacupuncture stimulation at the Taiyang acupoint, while the sham group underwent non-penetrating stimulation with a blunt wooden stick. No intervention was performed on the NC group. Refraction and axial length were measured by infrared autorefractor and optical coherence tomography(OCT)before modeling and at 4 wk after modeling. The expression levels of β-catenin and integrin β1 in the ciliary body of mice at 4 wk after modeling were detected using quantitative real-time PCR(qPCR)and Western blotting(WB).RESULTS:After modeling for 4 wk, compared with the NC group, the FDM and sham groups showed significantly decreased refractive power(both P<0.05), elongated axial length(both P<0.05), and increased β-catenin and integrin β1 expression. Compared with the FDM and sham groups, the Taiyang group showed significantly increased refractive power(both P<0.05), shortened axial length(both P<0.05), and decreased β-catenin and integrin β1 expression.CONCLUSION:Electroacupuncture stimulation at the Taiyang acupoint effectively delayed the progression of myopia in FDM mice, and this effect may be partially mediated through modulating the expression of β-catenin and integrin β1 in the ciliary body.

Insulin-like growth factor-1(IGF-1)is a multifunctional growth factor which plays an important role in various physiological and pathological processes of the body by regulating biological behaviors such as cell proliferation, differentiation, and migration. Studies have found that abnormal expression of IGF-1 in the retina, sclera and other eye tissues can participate in the occurrence, development and prognosis of various ophthalmic diseases by regulating retinal autophagy flux and angiogenesis, adipogenic differentiation of orbital soft tissues and degradation of scleral extracellular matrix. This paper systematically integrates the expression level changes and mechanism of action of IGF-1 in ophthalmic diseases such as diabetic retinopathy(DR), age-related macular degeneration(ARMD), retinopathy of prematurity(ROP), Graves' ophthalmopathy, myopia, corneal injury and uveal melanoma(UM), and combines the latest clinical and animal experimental evidence to evaluate the bright prospects and potential risks of IGF-1 targeted therapy, in order to provide new ideas and theoretical basis for the prevention and treatment of ophthalmic diseases.

OBJECTIVE: To explore the corrective strategies and effectiveness of osteotomy surgery for severe lower limb deformities in hypophosphatemic rickets. METHODS: A retrospective analysis was conducted on 29 patients with severe lower limb deformities of hypophosphatemic rickets who underwent surgical treatment between February 2012 and August 2024. There were 9 males and 20 females. The age ranged from 13 to 53 years, with an average of 24.6 years. All patients were deformities of both lower limbs, presenting as 24 cases of O-shaped legs, 2 cases of wind-blown deformities, and 3 cases of X-shaped legs. Based on the full-length films of both lower limbs in the standing position before operation, the osteotomy planes of the femur, tibia, and fibula were designed. Among them, if both the same-sided thigh and leg were deformed, staged surgeries of both lower limbs were selected. If only the thigh or leg were deformed, simultaneous surgeries of both lower limbs were selected. The femur deformity was corrected immediately after osteotomy at the deformed plane; the osteotomy fragment was temporarily controlled with an external fixator, which was removed after perform internal fixation with a steel plate. After fibular osteotomy, the Ilizarov frame or Taylor frame was installed on the tibia and fibula. The threaded rods were removed and then tibial osteotomy was performed on the deformed plane. Patients using the Taylor frame did not undergo deformity correction during operation. The external fixators were adjusted starting 7 days after operation to correct the varus, valgus, and rotational deformities of the lower limb. Patients using the Ilizarov frame corrected the rotational deformity of the tibia during operation. The external fixator was adjusted starting 7 days after operation to correct the varus and valgus deformities of the lower limb. During the treatment period, the patient could walk with partial weight-bearing on the operated limb with crutches. The external fixator was removed after the bone healed. Before operation and at last follow-up, the medial proximal tibial angle (MPTA), lateral distal tibial angle (LDTA), posterior proximal tibial angle (PPTA), anterior distal tibial angle (ADTA), anatomic lateral distal femoral angle (aLDFA), posterior distal femoral angle (PDFA), and mechanical axis deviation (MAD), lower limb rotation, limb length discrepancy (LLD) were measured. The self-made scoring criteria were adopted to evaluate the degree of lower limb deformity of the patients. RESULTS: All operations were successfully completed, and no complications such as nerve or vascular injury occurred. The adjustment time of the external fixator of the lower limb after operation was 28-46 days, with an average of 37.4 days. The wearing time of the external fixator ranged from 134 to 398 days, with an average of 181.5 days. Mild pin tract infections occurred in 2 limbs. The osteofascial compartment syndrome occurred in 1 limb after operation. No complications related to orthopedic adjustment of the external fixator occurred in other patients. All patients were followed up 6-56 months, with an average of 28.2 months. At last follow-up, full-length films of both lower limbs in the standing position showed that the coronal mechanical axes of the lower limbs of all patients returned to the normal. At last follow-up, MPTA, LDTA, PPTA, aLDFA, PDFA, MAD, lower limb rotation, LLD, and the score of lower limb deformity significantly improved when compared with those before operation ( P<0.05). There was no significant difference in ADTA between pre- and post-operation ( P>0.05). The degree of lower limb deformity were rated as moderate in 2 cases and poor in 27 cases before operation and as excellent in 7 cases, good in 18 cases, and moderate in 4 cases at last follow-up, with an excellent and good rate of 86.2%. CONCLUSION For severe lower limb deformities in hypophosphatemic rickets, immediate correction of deformities with femoral osteotomy and internal plate fixation, as well as gradually correction of deformities with tibiofibular osteotomy and circular external fixation (Ilizarov frame or Taylor frame), have satisfactory therapeutic effects.

OBJECTIVE: To investigate the effectiveness of single Taylor external fixator combined with biplanar osteotomy on correction of tibial multiplanar deformities. METHODS: Between October 2016 and December 2021, 11 patients with tibial multiplanar deformities (20 sides) were treated with single Taylor external fixator and biplanar osteotomy. Of them, 4 were male and 7 were female; the average age ranged from 13 to 33 years (mean, 21.9 years). Diagnosis included rickets severe genu varum deformity (7 cases, 14 sides), rickets severe genu valgum deformity (2 cases, 4 sides), multiple osteochondromatosis calf deformity (1 case, 1 side), neurofibromatosis medial lower leg anterior arch deformity with short of leg (1 case, 1 side). After fibular osteotomy and tibial multiplanar osteotomy, a Taylor external fixator was installed. After operation, the deformities were corrected successively and fixed completely. The osteotomy healed, then the external fixator was removed. Before operation and at 12 months after operation, the full-length X-ray films were taken. The leg-length discrepancy, medial proximal tibial angle (MPTA), lateral distal tibial angle (LDTA), posterior proximal tibial angle (PPTA), anterior distal tibial angle (ADTA), and tibial rotation angle were measured. The degree of lower limb deformity was scored with reference to a customized tibial mechanical axis scoring table. RESULTS: Osteotomy was successfully completed without neurovascular injury and other complications. The external fixator was adjusted for 28-46 days, with an average of 37 days, and the external fixator was worn for 136-292 days, with an average of 169 days. Mild needle infection during the fixation period occurred in 3 sides, refracture at the distal tibial osteotomy in 1 side after removing the external fixator, and nonunion of the distal fibular osteotomy in 1 side. All patients were followed up 369-397 days (mean, 375 days). At 12 months after operation, the lower limb discrepancy decreased, but there was no significant difference ( P>0.05). MPTA, LDTA, PPTA, ADTA, and tibial rotation angle improved, and the differences in LDTA, ADTA, and tibial rotation angle were significant ( P<0.05). The score of lower limb deformity was significantly higher than that before operation ( P<0.05), and the results were excellent in 9 sides, good in 8 sides, fair in 3 sides, with the excellent and good rate of 85%. CONCLUSION Single Taylor external fixator combined with biplanar osteotomy is effective in the correction of tibial multiplanar deformities.

OBJECTIVE: To investigate the correlation of procalcitonin (PCT), interleukin-6 (IL-6) and antithrombin III (AT III) with the severity of sepsis, and to compare the predictive value of the above indicators alone or in combination. METHODS: A retrospective cohort study was conducted. Eighty-five patients with sepsis admitted to the department of intensive care medicine of Shandong Provincial Hospital Affiliated to Shandong First Medical University from April 2021 to September 2022 were enrolled. General information, sequential organ failure assessment (SOFA) score and acute physiology and chronic health evaluation II (APACHE II) score within 24 hours of admission, inflammatory indicators [PCT, IL-6, serum amyloid A (SAA), neutrophil to lymphocyte ratio (NLR), and C-reactive protein (CRP)] and coagulation indicators (D-dimer and AT III) levels at admission, and 28-day prognosis were collected. The differences of the above indicators were compared among patients with different prognosis at 28 days and different severity of sepsis. The correlation between PCT, IL-6, AT III and the severity of sepsis was analyzed by Spearman rank correlation method. Receiver operator characteristic curve (ROC curve) was drawn to evaluate the predictive value of PCT, IL-6 and AT III alone or in combination on the 28-day death of patients with sepsis. RESULTS: Eighty-five patients were enrolled finally, 67 cases survived and 18 cases died at 28 days. The mortality was 21.2%. There were no statistical significant differences in gender, age and other general data between the two groups. The patients in the death group were more serious than those in the survival group, and PCT, IL-6, and CRP levels were significantly higher than those in the survival group [PCT (μg/L): 4.34 (1.99, 14.42) vs. 1.17 (0.31, 3.94), IL-6 (ng/L): 332.40 (50.08, 590.18) vs. 61.95 (31.64, 194.20), CRP (mg/L): 149.28 (75.34, 218.60) vs. 83.23 (48.22, 174.96), all P < 0.05], and AT III activity was significantly lower than that in the survival group [(53.67±28.57)% vs. (80.96±24.18)%, P < 0.01]. However, there were no significant differences in D-dimer, NLR and SAA between the two groups. Among the 85 patients, 36 had sepsis with single organ dysfunction, 29 had sepsis with multiple organ dysfunction, and 20 had septic shock with multiple organ dysfunction. With the increase of the severity of sepsis, PCT and IL-6 levels gradually increased [PCT (μg/L): 0.36 (0.19, 1.10), 3.00 (1.22, 9.94), 4.34 (2.18, 8.86); IL-6 (ng/L): 43.99 (20.73, 111.13), 100.00 (45.37, 273.00), 332.40 (124.4, 693.65)], and the activity of AT III decreased gradually [(89.81±21.42)%, (71.97±24.88)%, and (53.50±25.41)%], all with statistically significant differences (all P < 0.01). Spearman rank correlation analysis showed that PCT and IL-6 levels in sepsis patients were significantly positively correlated with the severity of the disease (r values were 0.562 and 0.517, respectively, both P < 0.01), and AT III activity was significantly negatively correlated with the severity of the disease (r = -0.523, P < 0.01). ROC curve analysis showed that PCT, IL-6, and AT III alone or in combination had some predictive value for the death of sepsis patients at 28 days. The area under the ROC curve (AUC) of the above three indicators in combination was higher than that of the individual tests (0.818 vs. 0.722, 0.725, and 0.770), with a sensitivity of 83.3% and a specificity of 73.1%. CONCLUSIONS PCT, IL-6, and AT III were significantly correlated with the severity of sepsis patients. The combined assay of the above three indicators can effectively improve the prediction of the prognosis of sepsis patients.

OBJECTIVE To study th e pharmacodynamics and pha rmacokinetics of Qinglian ningxin capsule in rats with ischemic arrhythmia. METHODS Totally 30 male SD rats were randomly divided into blank control group ，model control group ， Qinglian ningxin capsule group （4.00 g/kg），Artemisia annua group（1.43 g/kg），Coptis chinensis group（0.42 g/kg），with 6 rats in each group. Administration groups were given relevant medicine intragastrically ；model control group and blank control group were given normal saline intragastrically ，once a day ，for consecutive 7 days. After last medication ，except for blank control group，other groups were given Posterior pituitary injection via tail vein （1 u/kg） to induce ischemic arrhythmia model. electrocardiogram changes of rats in each group were recorded. Another 36 rats were randomly divided into Qinglian ningxin capsule model group and Qinglian ningxin capsule control group （4.00 g/kg），A. annua model group and A. annua control group （1.43 g/kg），C. chinensis model group and C. chinensis control group （0.42 g/kg）. After the rats in each model group were injected with Posterior pituitary injection （1 u/kg）via tail vein ，administration groups were given relevant drugs intragastrically ， and control groups were given constant volume of normal saline intragastrically. Blood was taken from the orbit at different time points（0，0.25，0.75，1，2，4，6，8，12 and 24 h）. The concentrations of berberine hydrochloride and artemisinin in plasma were determined by HPLC ，and the pharmacokinetic parameters were calculated by WinNonlin 7.0 software. RESULTS Compared with the model control groups ，Qinglian ningxin capsule could significantly improve the heart rate slowing of rats and redu ced the prolongation of PR interval and QT interval significantly ，and the effects were generally better than those of A. annua group and C. chinensis group（P＜0.05）. Compared with A. annua control group and C. chinensis control group ，cmax，AUC0－t and AUC 0－∞ of berberine hydrochloride and artemisinin were increased significantly in Qinglian ningxin capsule control group，while CL was decreased significantly ；t1/2z of artemisinin was prolonged significantly （P＜0.05）. Compared with Qinglian ningxin capsule control group ，cmax（except artemisinin ），AUC0－t，AUC0－∞，MRT0－t and MRT 0－∞（except artemisinin ）of berberine hydrochloride and artemisinin were increased significantly in Qinglian ningxin capsule model group ，while CL was decreased significantly（P＜0.05）. CONCLUSIONS Qinglian ningxin capsule could significantly improve ischemic arrhythmia better than A. annua and C. chinensis ，and can improve the absorption of berberine hydrochloride and artemisinin in model rats and slow down their elimination.

Background/Aims: Crohn’s disease (CD) primarily affects young female adults of reproductive age. Few studies have been conducted on this population’s ovarian reserve status. The aim of study was to investigate potential risk factors associated with low ovarian reserve, as reflected by serum anti-Müllerian hormone (AMH) in women of reproductive age with CD. Methods: This was a case-control study. Cases included 87 patients with established CD, and healthy controls were matched by age, height and weight in a 1:1 ratio. Serum AMH levels were measured by enzyme-linked immunosorbent assay. Results: The average serum AMH level was significantly lower in CD patients than in control group (2.47±2.08 ng/mL vs. 3.87±1.96 ng/mL, respectively, P<0.001). Serum AMH levels were comparable between CD patients and control group under 25 years of age (4.41±1.52 ng/mL vs. 3.49±2.10 ng/mL, P=0.06), however, serum AMH levels were significantly lower in CD patients over 25 years of age compared to control group (P<0.05). Multivariable analysis showed that an age greater than 25 (odds ratio [OR], 10.03; 95% confidence interval [CI], 1.90–52.93, P=0.007), active disease state (OR, 27.99; 95% CI, 6.13–127.95, P<0.001) and thalidomide use (OR, 15.66; 95% CI, 2.22–110.65, P=0.006) were independent risk factors associated with low ovarian reserve (serum AMH levels <2 ng/mL) in CD patients. Conclusions Ovarian reserve is impaired in young women of reproductive age with CD. Age over 25 and an active disease state were both independently associated with low ovarian reserve. Thalidomide use could result in impaired ovarian reserve.

Objective There have been many techniques proposed for the reconstruction of pancreatic digestive continuity to prevent fistula (PF) formation, but this is still highly debated. We carried out a systematic review and meta- analysis to determine the effectiveness of methods of anastomosis after pancreaticoduodenectomy (PD). Methods A full literature search was conducted in the Cochrane Controlled Trials Register Databases, Medline, et al.Randomized controlled trials(RCTs) were considered for inclusion. Analysis was carried out using Revman software. Results In all, 10 RCTs including a total of 1 408 patients were included, the pancreaticogastrostomy (PG) and pancreaticojejunostomy (PJ) groups, duct to mucosa PJ and PJ, binding PJ and PJ, pancreatic duct without anastomosis PJ and PJ. The meta-analysis showed that the PF, postoperative complications, biliary fistula, mortality, re-operation and hospital stay were not statistically different among four methods(P>0.05).Conclusions No ideal technique of pancreatic reconstruction after PD is found to be applicable to all kinds of pancreatic remnants in this systematic review and meta-analysis.

Background and purpose: L-asparaginase (L-Asp) is an important drug in the treatment of childhood lymphoid neoplasms at present, but a lot of adverse reactions of L-Asp were observed. Pegasparaginase (PEG-Asp) is available in China in recent years. This study aimed to explore efifcacy and side-effect of PEG-Asp as ifrst-line treatment in childhood acute lymphoblastic leukemia (ALL) and lymphoblastic lymphoma (LBL). Methods:A total number of 211 ALL or LBL patients were treated with CCLG 2008 or BFM-90 protocol with PEG-Asp or L-Asp between Apr. 2008 and Mar. 2013;42 patients, among whom, were 35 ALL patients and 7 LBL patients, were treated with PEG-Asp as ifrst-line treatment;169 patients were treated with L-Asp as ifrst-line treatment (including 53 patients treated with L-Asp during induction protocol; with PEG-Asp during consolidate protocol). The clinical outcome and adverse reaction of PEG-Asp with L-Asp were observe and compared. Results: There were 35 ALL patients in PEG-Asp ifrst-line treatment group and the complete remission rate after 1 course of PEG-Asp was 97.1%,however, which was 83.3%of high risk ALL patients. The complete remission rate of 7 LBL patients of PEG-Asp ifrst-line treatment group was 57.1%. There was no signiifcant difference between 2 groups (P>0.05). Thirty-four patients relapsed including 5 patients of PEG-Asp ifrst-line treatment group, 16 patients of L-Asp ifrst-line treatment group and 13 patients treated with L-Asp during induction protocol and with PEG-Asp during consolidate protocol. Thirty-one patients died including 3, 18, 10 patients in 3 groups respectively. Twenty-two patients died of relapse, 4 died without remission, 5 died of complications. There was also no signiifcant difference between 2 groups (P>0.05). The incidence rates of adverse reactions were 47.6% and 63.3% respectively. Anaphylaxis, liver functions abnormalities, blood coagulation abnormalities, gastrointestinal reaction, hyperglycemia and pancreatitis were common in our patients. The incidence rate of anaphylaxis in PEG-Asp as ifrst-line treatment group was lower than other groups (P=0.03). But there was no signiifcant difference been observed in the incidence of other adverse reaction. Conclusion: The short-term efifcacy of PEG-Asp as the ifrst-line treatment in childhood leukemia and lymphoma was satisfactory and the incidence rate of anaphylaxis was lower. However, we will still pay much attention to adverse reaction monitoring of PEG-Asp.
