Based on commonly used acupoints in the clinical acupuncture treatment of functional dyspepsia （FD）， this study systematically analyzes the therapeutic differences and synergistic effects between local and distal point selection. It also examines the suitability of primary acupoint selection for different FD subtypes， postprandial distress syndrome （PDS） and epigastric pain syndrome （EPS）. The findings suggest that a combination of local and distal acupoints may be more appropriate as primary points for PDS， whereas local acupoints alone may be more suitable for EPS. Additionally， the study explores the impact of various factors， such as stimulation techniques， needling order， intensity or stimulation parameters， and depth， on the efficacy of acupuncture. It concludes that the intrinsic properties of acupoints are the primary determinants of therapeutic direction. Other factors mainly influence the magnitude rather than the direction of the effect. Future research may further investigate how different acupoint combinations， local versus distal， affect the treatment outcomes of FD subtypes， providing new insights for clinical acupuncture prescriptions.

Objective:To explore the feasibility of using quantitative parameters of double contrast-enhanced ultrasound (DCUS) to noninvasively predict lymphatic metastasis in gastric cancer before operation.Methods:From December 2021 to October 2023, 119 patients undergoing gastrectomy at the Second Hospital & Clinical Medical School, Lanzhou University, were enrolled retrospectively. Based on the pathological findings, they were divided into lymph node metastasis (N1, 94 cases) and non-lymph node metastasis (N0, 25 cases) groups. All patients underwent DCUS within 3 days before surgery. Previous to DCUS, lesions′ location and ultrasonic T-staging were recorded by conventional ultrasound. Quantitative parameters such as arrival time (AT), time to peak (TTP), baseline intensity (BI), peak intensity (PI) and wash-in slope (WIS) were obtained by the time-intensity curve (TIC) automatically, and then manually calculated enhanced intensity (ΔPI=PI–BI) and enhanced time (ΔTTP=TTP–AT). Binary Logistic regression analysis was used to screen independent risk factors for predicting lymph nodes metastasis in gastric cancer, and regression models were established.Results:Statistical tests revealed significant differences in ultrasonic T-staging ( P<0.001) and degree of differentiation ( P=0.015) between N1 and N0 group. Among DCUS quantitative parameters, statistical differences in PI, ΔPI and WIS were observed between the two groups (all P<0.05), while no significant differences were found in BI, AT, TTP and ΔTTP (all P>0.05). Logistic regression analysis showed that ultrasonic T-staging and WIS were independent risk factors for predicting lymphatic metastasis. The regression model built on the above two factors performed well in predicting lymph nodes metastasis, with an area under the curve of 0.905, accuracy of 93.3% (superior to the prediction model based on DCUS quantitative parameters alone, P<0.05), sensitivity of 95.7% and specificity of 84.0%. Conclusions:DCUS quantitative parameters may be helpful to evaluate lymphatic metastasis of gastric cancer prior to surgery, and the accuracy of prediction would be improved by combing with ultrasonic T-staging.

Objective: To analyze the epidemiological characteristics and trends of chronic disease mortality among children aged 0-14 in China during 2012-2021, so as to provide scientific basis for the formulation of prevention strategies for chronic diseases in children. Methods: The descriptive epidemiological analysis was conducted for chronic disease mortality among children aged 0-14 during 2012 to 2021 from China Cause of Death Surveillance Data Set, and the Joinpoint regression models were used to analyze the average annual percentage change (AAPC) of child chronic disease mortality. Results: From 2012 to 2021, the mortality rates of chronic diseases among children aged 0-14 years in China (23.33/100 000, 19.54/100 000, 19.27/100 000, 17.69/ 100 000 , 16.87/100 000, 16.44/100 000, 14.49/100 000, 13.79/100 000, 11.61/100 000, 9.43/100 000)showed a decreasing trend (AAPC=-7.94%, P <0.01). The overall mortality rates for boys and girls and for chronic diseases were decreasing in both urban and rural areas (AAPC=-8.44%, -7.05%, -8.42%, -6.77%, P <0.05). The average annual mortality rate of chronic diseases was higher in boys (16.81/100 000) than in girls (13.96/100 000) ( χ 2=526.44, P <0.01). The average annual mortality rate from chronic diseases among children was higher in urban (15.98/100 000) than in rural areas (13.46/100 000) in the central region, and higher in rural (19.75/100 000) than in urban areas (15.96/100 000) in the western region ( χ 2=117.63, 190.25, P < 0.01 ). Except for malignant tumors, the trend of overall mortality rates of congenital abnormalities, neurological and mental disorders, cardiovascular diseases, and digestive system diseases were all decreasing (AAPC=-11.48%, -2.92%, -7.82%, -12.51 %, P <0.05). Conclusions The overall mortality rate of chronic diseases in children in China shows a downward trend during 2012-2021, but the situation of chronic disease prevention and control is still severe. Targeted prevention strategies should be adopted, focusing on the prevention and health care of males, children under 5 years old.

AIM: To analyze the effect of full-femtosecond small incision lenticule extraction(SMILE)on the treatment of high myopia based on propensity score matching.METHODS: A total of 48 cases(48 eyes)of high myopia patients who underwent SMILE surgery in our hospital from May 2019 to May 2021 were selected as the observation group, and 48 cases(48 eyes)of high myopia patients who underwent FS-LASIK surgery were matched using propensity score matching as the control group. Follow up for 6mo after surgery, the changes in cylindrical, central corneal thickness, uncorrected visual acuity(UCVA), corneal endothelial cell related indicators [percentage of hexagonal endothelial cells(6A), coefficient of variation(CV)of endothelial cell area, central corneal endothelial cell density(ECD)] and corneal biomechanical indicators [simulated Goldman intraocular pressure(IOPg), corneal hysteresis(CH), corneal resistance factor(CRF), corneal compensated intraocular pressure(IOPcc)] between the two groups were compared, and the incidence of complications in both groups of patients was recorded.RESULTS: Both groups of patients showed significant improvements in cylindrical and UCVA at 3 and 6mo after surgery, as well as decreased central corneal thickness, corneal endothelial cells, and corneal biomechanics related indicators. The changes in the observation group were more significant(all P<0.05). During the follow-up period, there was no significant difference in the incidence of complications between the observation group and the control group(8% vs. 17%, P>0.05).CONCLUSION: SMILE has a definite effect on patients with high myopia and is helpful to improve visual acuity.

OBJECTIVE: This study was aimed at investigating the carrier rate of, and molecular variation in, α- and β-globin gene mutations in Hunan Province. METHODS: We recruited 25,946 individuals attending premarital screening from 42 districts and counties in all 14 cities of Hunan Province. Hematological screening was performed, and molecular parameters were assessed. RESULTS: The overall carrier rate of thalassemia was 7.1%, including 4.83% for α-thalassemia, 2.15% for β-thalassemia, and 0.12% for both α- and β-thalassemia. The highest carrier rate of thalassemia was in Yongzhou (14.57%). The most abundant genotype of α-thalassemia and β-thalassemia was -α ^3.7/αα (50.23%) and β ^IVS-II-654/β ^N (28.23%), respectively. Four α-globin mutations [CD108 (ACC>AAC), CAP +29 (G>C), Hb Agrinio and Hb Cervantes] and six β-globin mutations [CAP +8 (C>T), IVS-II-848 (C>T), -56 (G>C), beta nt-77 (G>C), codon 20/21 (-TGGA) and Hb Knossos] had not previously been identified in China. Furthermore, this study provides the first report of the carrier rates of abnormal hemoglobin variants and α-globin triplication in Hunan Province, which were 0.49% and 1.99%, respectively. CONCLUSION Our study demonstrates the high complexity and diversity of thalassemia gene mutations in the Hunan population. The results should facilitate genetic counselling and the prevention of severe thalassemia in this region.

OBJECTIVE: To investigate the effectiveness of tibial transverse transport (TTT) combined with modified neurolysis in treatment of diabetic foot ulcer (DFU) through a prospective randomized controlled study. METHODS: The patients with DFU and diabetic peripheral neuropathy, who were admitted between February 2020 and February 2022, were selected as the research objects, of which 31 cases met the selection criteria and were included in the study. The patients were divided into two groups by random number table method. The 15 patients in the trial group were treated with TTT combined with modified neurolysis, and the 16 patients in the control group received treatment with TTT alone. There was no significant difference in gender, age, duration of DFU, ulcer area, Wagner classification, as well as preoperative foot skin temperature, visual analogue scale (VAS) score, ankle-brachial index (ABI), motor nerve conduction velocity (MNCV) of the common peroneal nerve, MNCV of the tibial nerve, MNCV of the deep peroneal nerve, two-point discrimination (2-PD) of heel, and cross-sectional area (CSA) of the common peroneal nerve between the two groups ( P>0.05). The time for ulcer healing, foot skin temperature, VAS scores, ABI, 2-PD of heel, and CSA of the common peroneal nerve before operation and at 6 and 12 months after operation were recorded and compared between groups. The differences in MNCV of the common peroneal nerve, MNCV of the tibial nerve, and MNCV of the deep peroneal nerve between pre-operation and 12 months after operation were calculated. RESULTS: All patients in both groups were followed up 12-24 months (mean, 13.9 months). The surgical incisions in both groups healed by first intention and no needle tract infections occurred during the bone transport phase. Ulcer wounds in both groups healed successfully, and there was no significant difference in the healing time ( P>0.05). During the follow-up, there was no ulcer recurrences. At 12 months after operation, the MNCV of the common peroneal nerve, the MNCV of the tibial nerve, and the MNCV of the deep peroneal nerve in both groups accelerated when compared to preoperative values ( P<0.05). Furthermore, the trial group exhibited a greater acceleration in MNCV compared to the control group, and the difference was significant ( P<0.05). The foot skin temperature, VAS score, ABI, 2-PD of heel, and CSA of the common peroneal nerve at 6 and 12 months after operation significantly improved when compared with those before operation in both groups ( P<0.05). The 2-PD gradually improved over time, showing significant difference ( P<0.05). The 2-PD of heel and VAS score of the trial group were superior to the control group, and the differences were significant ( P<0.05). There was no significant difference in ABI, foot skin temperature, and CSA of the common peroneal nerve between groups after operation ( P>0.05). CONCLUSION Compared with TTT alone, the TTT combined with modified neurolysis for DFU can simultaneously solve both microcirculatory disorders and nerve compression, improve the quality of nerve function recovery, and enhance the patient's quality of life.

OBJECTIVE: To examine whether the combination of Naoxintong Capsule with standard care could further reduce the recurrence of ischemic stroke without increasing the risk of severe bleeding. METHODS: A total of 23 Chinese medical centers participated in this trial. Adult patients with a history of ischemic stroke were randomly assigned in a 1:1 ratio using a block design to receive either Naoxintong Capsule (1.2 g orally, twice a day) or placebo in addition to standard care. The primary endpoint was recurrence of ischemic stroke within 2 years. Secondary outcomes included myocardial infarction, death due to recurrent ischemic stroke, and all-cause mortality. The safety of drugs was monitored. Results were analyzed using the intention-to-treat principle. RESULTS: A total of 2,200 patients were enrolled from March 2015 to March 2016, of whom 143 and 158 in the Naoxintong and placebo groups were lost to follow-up, respectively. Compared with the placebo group, the recurrence rate of ischemic stroke within 2 years was significantly lower in the Naoxintong group [6.5% vs. 9.5%, hazard ratio (HR): 0.665, 95% confidence interval (CI): 0.492-0.899, P=0.008]. The two groups showed no significant differences in the secondary outcomes and safety, including rates of severe hemorrhage, cerebral hemorrhage and subarachnoid hemorrhage (P>0.05). CONCLUSION The combination of Naoxintong Capsule with standard care reduced the 2-year stroke recurrence rate in patients with ischemic stroke without increasing the risk of severe hemorrhage in high-risk patients.

Objective: To evaluate the efficacy of the Hodgkin lymphoma (HL)-2013 regimen in the treatment of children with HL, and to investigate the prognostic factors of childhood HL. Methods: Clinical data of 145 children (aged ≤18 years) with newly diagnosed HL, treated with HL-2013 regimen in 8 tertiary referral centers for childhood cancer from August 2011 to April 2021 were analyzed retrospectively. All the diagnosis were confirmed by histopathological morphology and immunohistochemical examination. The clinical characteristics and treatment outcomes were summarized, and the patients were divided into different groups according to clinical characteristics. Kaplan-Meier method was used for survival analysis, and the comparison of survival rates between groups was performed with Log-rank test. Results: Of the 145 cases, there were 115 males and 30 females, the age at diagnosis was 7.9 (5.8, 10.6) years. Cervical lymph node enlargement (114 cases, 78.6%) was the common symptom of the disease, and 57 patients (39.3%) were accompanied by large masses. The most common pathological classification was mixed cell type (93 cases, 64.1%). According to the Ann Arbor staging system, there were 9 cases of stage Ⅰ, 62 cases of stage Ⅱ, 45 cases of stage Ⅲ, 29 cases of stage Ⅳ. According to the risk stratification: there were 14 cases of low-risk group, 76 cases of medium-risk group and 55 cases of high-risk group. Of all patients, 68 cases (46.9%) achieved an early complete remission (CR) after 2 courses of chemotherapy, and the CR rate was 93.8% (136/145) after first-line treatment. Disease recurrence or progression occurred in 22 cases (15.2%). Of all patients, 125 cases survived, 6 cases died and 14 cases were lost to follow-up. Among the survived cases, 123 cases were continuously at CR state,and the follow-up time was 55 (40, 76) months. The 5-year overall survival (OS) and event free survival (EFS) rates were (95.3±1.9)% and (84.2±3.0)% for the entire group, respectively. 5-year OS and EFS rates for patients with stage Ⅲ-Ⅳ were both lower than those for patients with stage Ⅰ-Ⅱ (χ²=6.28 and 7.58, both P<0.05), the 5-year OS and EFS rates for patients in high-risk group were both lower than those for patients in low-risk and medium-risk group (χ²=10.93, 7.79, both P<0.05). The 5-year OS rates for the patient with early CR and without early CR were 100.0% and (90.9±3.6)% (χ²=5.77, P=0.016). EFS rates for the patient with early CR (68 cases) and without early CR (77 cases) were (93.8±3.0)% and (75.8±5.0)% (χ²=8.78, P=0.003). Conclusions: HL-2013 regimen is significantly effective in the treatment of pediatric HL. However, the patients in high-risk group and those without early CR are prone to disease recurrence or progression. Stage Ⅲ-Ⅳ and without early CR were associated with worse prognosis.

Objective:To compare the effect on scar in donor area of small-and medium-sized anterolateral thigh perforator flap(ALTPF) harvested from superficial and deep layer of the superficial fascia.Methods:A retrospective analysis was performed on 31 patients who had small-and medium-sized soft tissue defects in the extremities and admitted to the Department of Burns and Plastic Surgery of the Affiliated Hospital of Zunyi Medical University from January 2020 to February 2021. All the patients were repaired with ALTPFs. The sizes of defect ranged from 5.0 cm×3.5 cm to 17.0 cm×6.0 cm, and the flaps sized from 6.0 cm×4.0 cm to 20.0 cm×6.0 cm. Fifteen ALTPFs were harvested from superficial layer of superficial fascia (modified group), and 16 harvested from deep layer of superficial fascia (traditional group). The flap donor sites were sutured directly using the "Zunyi suture method". Appearance of scars was assessed within the Vancouver Scar Scale (VSS) and in addition the width of scars was been recorded. The data of the 2 groups were statistically analyzed. There was statistically significant difference when P<0.05. Results:All flaps were successfully viable. All wounds healed in Ⅰ stage and donor incisions healed in Ⅰ stage at 2-3 weeks after the surgery. All patients entered postoperative follow-up for 6 to 26 months, with a mean of 10.7 months. There was no ischaemic necrosis at the donor margin. There was no significant difference between circumference of thighs between the modified group and traditional group [ (0.10±0.40) cm and (0.03±0.39) cm, respectively]( P>0.05). VSS were found lower in the modified group (2.00±1.46) than that in the traditional group (3.06±1.61)( t=2.132, P=0.039), as well as the scars were found smaller at the widest point[(6.67±3.85) cm and(16.06±6.63) cm, respectively. t=2.807, P=0.005]. The differences were statistically significant( P<0.05). Conclusion:Small-and medium-sized ALTPFs, harvested in the superficial layer of superficial fascia, can reduce the width of the donor scar, improve the surgical outcome and increase patient satisfaction.

Objective: To investigate the distribution characteristics of LymphGen genotyping in a diffuse large B-cell lymphoma (DLBCL) population and verify its prognostic value. Methods: We collected the clinical data and paraffin-embedded tumor tissue samples of 155 patients with newly diagnosed DLBCL in the People's Hospital of Xinjiang Uygur Autonomous Region from June 2014 to December 2020. DNA was extracted from tumor tissue and 475 gene mutations were detected by next-generation sequencing technology. We investigated the distribution of LymphGen genotyping in the DLBCL population, patients with different COO genotypes in the Xinjiang region, and their effects on PFS and OS. Results: ①Among 155 patients, 105 patients (67.7%) could be genotyped, including 14 (9.0%) for MCD, 26 (16.8%) for BN2, 10 (6.5%) for N1, 8 (5.2%) for EZB, 27 (17.4%) for A53, and 20 (12.9%) for ST2. ②The distribution of each gene subtype was different in different cell origin (COO) types (P=0.021) . ST2 was dominant in the germinal center type (GCB) group (28.8%) , and A53 and MCD were dominant in the non-GCB group (35.8%, 17.0%) . The BN2 type was the most common in both groups (23.1%, 26.4%) . ③There were statistically significant differences in progression-free survival (PFS) and overall survival (OS) among different gene subtypes (P=0.031 and 0.005, respectively) . N1 and A53 had poor prognosis. The 2-year PFS and OS rates of N1 were both (21.3±18.4) %, and the 3-year PFS and OS rates of A53 were (60.9±11.3) %, (46.8±10.9) %, respectively. ④ The 3-year PFS and OS rates of MCD were the best, but the 5-year PFS and OS rates were worse. ⑤In the ROC curve of LymphGen genotyping for OS prediction, the AUC was 0.66, showing a certain degree of differentiation. Conclusion: LymphGen genotyping in the DLBCL population was different from previous reports and was of great significance for the prognosis of patients with DLBCL.
