Objective:To observe the efficacy of transcutaneous electrical acupoint stimulation (TEAS) when it is combined with warm moxibustion scraping therapy (WMST) in the treatment of myofascial pain syndrome (MPS) in the lumbodorsal region.Methods:A total of 112 patients with lumbodorsal MPS were randomly divided into a control group and a combination group, each of 56. All of the patients received TEAS, but those in the combined group additionally received warm moxibustion scraping therapy. The treatment consisted of 3 consecutive courses, with each course lasting 2 weeks and a 1-day rest interval between courses. Before the treatment and after completing 3 courses (post-treatment), the therapeutic effects were evaluated using traditional Chinese medicine (TCM) syndrome scores, visual analogue scale (VAS) ratings for pain, a pain rating index (PRI), present pain intensity (PPI), the Oswestry Disability Index (ODI), and the Pittsburgh Sleep Quality Index (PSQI).Results:After the treatment, significant decreases were observed in the average TCM syndrome, VAS pain, PRI, PPI, ODI and PSQI scores of both groups, but the combination group′s averages were all significantly lower than those of the control group. Efficacy among the combination group (92.9%) was significantly higher than among the controls (62.5%).Conclusions:Supplementing TEAS with warm moxibustion scraping can more effectively relieve lumbodorsal pain and dysfunction among patients with lumbodorsal MPS, and improve their sleep quality.

Objective:To explore the correlation between Chinese visceral adiposity index (CVAI) and metabolic associated fatty liver disease (MAFLD) so as to evaluate its predictive value for MAFLD.Methods:Six hundred and thirteen cases admitted to the Department of Gastroenterology, Zhongshan Hospital Affiliated to Dalian University from June 2022 to August 2023 were selected and divided into the MAFLD group ( n=312) and the non-MAFLD group ( n=301) according to the diagnostic criteria of MAFLD. The clinical data differences between the two groups were compared. The MAFLD group was divided into a mild MAFLD group ( n=243) and a moderate to severe MAFLD group ( n=69) according to the liver/spleen CT value. The differences in body fat indices such as CVAI, visceral fat index (VAI), and visceral fat area (VFA) were compared between subjects with different degrees of MAFLD. The Spearman test was used to analyze the correlation between CVAI, VAI, and various clinical indicators. The subjects were divided into groups (Q1-Q4) according to the quartile levels of CVAI and VAI, and the distribution of MAFLD conditions among the groups was compared. Logistic regression analysis was used to determine the occurrence risk of MAFLD at different CVAI and VAI levels. The receiver operating characteristic curve was drawn. The area under the receiver operating characteristic curve (AUC) was calculated to evaluate the predictive value of CVAI, VAI, VFA, waist circumference, and body mass index for MAFLD. The DeLong test was used to compare the differences in the AUC of each predictive index. Results:The prevalence of hypertension and type 2 diabetes mellitus, and the levels of systolic blood pressure, diastolic blood pressure, CVAI, VAI, VFA, subcutaneous fat area, waist circumference, body mass index, total cholesterol, triglycerides, low-density lipoprotein cholesterol, fasting blood glucose, fasting insulin, homeostasis model assessment of insulin resistance, high-sensitivity C-reactive protein, alanine aminotransferase, aspartate aminotransferase, γ-glutamyl transferase, and serum uric acid were higher in the MAFLD group than the non-MAFLD group ( P<0.05), while the level of high-density lipoprotein cholesterol was lower than the non-MAFLD group ( P<0.001). The levels of CVAI, VAI, VFA, waist circumference, and body mass index were higher in the mild and the moderate to severe MAFLD group than those in the non-MAFLD group ( P<0.001). The detection rate of MAFLD gradually increased( χ2=176.953, 133.659, P<0.001) with the increase of CVAI and VAI levels. Correlation analysis showed that CVAI was positively correlated with VFA ( r=0.755, P<0.001) and the homeostasis model assessment of insulin resistance ( r=0.579, P<0.001). Multivariate logistic regression analysis showed that after adjusting for various risk factors, the risk of MAFLD in the Q4 group of the CVAI subgroup was still 7.159 times that of the Q1 group (95% CI:3.126-16.392, P<0.001), and the risk of MAFLD in the Q4 group of the VAI subgroup was still 4.667 times that of the Q1 group (95% CI: 2.187-9.962, P<0.001). The receiver operating characteristic curve results showed that the AUC of CVAI for predicting MAFLD was similar to that of VFA (0.822 vs. 0.826), and higher than that of VAI (AUC 0.772), waist circumference (AUC 0.796), and body mass index (AUC 0.755). The optimal critical value of CVAI for predicting the risk of MAFLD was 125.50, with sensitivity and specificity at 70.5% and 79.1%, respectively. Conclusion:The patient's risk of MAFLD increases with the rise of CVAI level, and CVAI has a favorable predictive value for the occurrence of MAFLD.

[Purpose]To analyze the incidence and mortality of liver cancer in Fusui County of Guangxi Zhuang Autonomous Region in 2019 and the trend of change from 201 1 to 2019.[Meth-ods]Based on the incidence and mortality data of liver cancer in Fusui County from 2011 to 2019,the crude incidence rate,crude mortality rate,age-standardized rate by Chinese standard population(ASIRC/ASMRC),age-standardized rate by world standard population(ASMRW/ASM-RW),disability-adjusted life years(DALY),years of life lost(YLL),years of lived with disability(YLD)were calculated.The Joinpoint linear regression model was used to calculate the average annual percentage change(AAPC)of the ASIRC/ASMRC and DALY rate of liver cancer in Fusui County from 2011 to 2019.[Results]In 2019,there were 345 new cases and 298 deaths of liver cancer in Fusui County,accounting for 28.49％and 35.86％of all new cases and death cases of malignant tumors in Fusui County,respectively.The crude incidence rate,ASIRC and ASIRW were 74.71/105,67.55/105 and 65.63/105,respectively;the crude mortality rate,ASMRC and ASMRW were 64.53/105,58.78/105 and 56.88/105,respectively.In 2019,ASIRC/ASMRC of men were higher than those of women(105.32/105 and 95.67/105 for men;27.26/105 and 19.11/105 for women).The peak incidence and mortality rates were in the 65～69 and 80～84 age groups,re-spectively.The incidence rate of liver cancer in Fusui County declined from 82.50/105 in 2011 to 67.55/105 in 2019,with an AAPC of-3.01％(P=0.024),but the mortality rate did not have sig-nificant changes(AAPC=-1.44％,P=0.224).The rate of DALY decreased from 14.51/105 to 10.36/105,with an AAPC of-2.82％(P=0.050).[Conclusion]The incidence rate and DALY rate of liv-er cancer in Fusui County showed an overall decreasing trend from 2011 to 2019,but still re-mained at a high level.It is necessary to further strengthen the prevention,screening and early treatment of liver cancer in this region,especially for men and the elderly.

Objective To compare the effectiveness of Defocus Incorporated Multiple Segments (DIMS) and High Aspheric Lenslet (HAL) defocus lenses in controlling myopia. Methods A total of 214 children and adolescents who were fitted with defocus lenses (DIMS or HAL) in our hospital from January to June 2023 were selected, including 100 cases in DIMS group and 114 cases in the HAL group. Changes in parameters such as spherical lens power, cylindrical lens power, spherical equivalent (SE), corneal curvature (K), axial length (AL), binocular accommodative response (BCC), positive/negative relative accommodation (PRA/NRA), distance/near latent phoria (DLP/NLP), and accommodative convergence to accommodation ratio (AC/A) were compared between the two groups before wearing and after wearing the lenses for 6 months, and the effectiveness of myopia control between DIMS and HAL was further compared. Results After wearing the lenses (DIMS or HAL) for 6 months, the average increase in axial length was (0.09±0.14) mm, the average increase in spherical lens power was (-0.11±0.23) D, the average increase in astigmatism was (-0.07±0.16) DC, and the average increase in spherical equivalent was (-0.15±0.24) D, with statistically significant differences observed for all these changes (t=9.24, -7.27, -6.60, -9.03, respectively, P < 0.001). Compared with parameters before wearing the lenses, statistically significant differences were noted after wearing for 6 months in spherical lens power, cylindrical lens power, SE, BCC, PRA, DLP, average K, and AL (P≤0.001), except for NRA (t=-0.12, P>0.05), NLP (t=-0.28, P>0.05), and AC/A (t=0.33, P>0.05). The differences in parameters between the two groups after wearing the lenses for 6 months showed a statistically significant difference only in the AL difference (t=4.38, P≤0.001), with no statistically significant differences observed for other parameter differences (P>0.05). Conclusion Wearing defocus lenses has a positive effect on controlling myopia, delaying axial length elongation, and maintaining binocular visual function balance.

Objective:To explore the feasibility of autologous transplantation of frozen-thawed ovarian tissue to induce pubertal development in adolescent females.Methods:Before hematopoietic stem cell transplantation in patient with severe β-thalassemia, 11 pieces of ovarian tissue were frozen in the Center of Reproductive Medicine, the Sixth Affiliated Hospital of Sun Yat-sen University in 2019. The patient was diagnosed as premature ovarian failure after hematopoietic stem cell transplantation. There were no signs of puberty development and menarche. Orthotopic ovarian tissue transplantation was performed for the patient through laparoscopy, and a total of 5 pieces of ovarian tissue were transplanted on January 20, 2022. Postoperatively, we followed up the sex hormone levels, growth and development of the patients and menarche.Results:The patient developed menarche 5 months after ovarian transplantation. The levels of sex hormones showed that follicle-stimulating hormone and luteinizing hormone were significantly decreased, and estradiol levels were significantly increased, indicating that ovarian tissue transplantation was successful, and follicles had begun to recruit and develop. The patient's ultrasonography revealed a markedly enlarged uterus and a thickened endometrium. Antral follicles were detected in the left implantation site of pelvic cavity.Conclusion:Cryopreservation of ovarian tissue is recommended for fertility preservation in prepubertal children. Autologous frozen-thawed ovarian tissue transplantation can induce natural puberty development and restore the reproductive endocrine function in children with ovarian failure, delayed puberty development or even stagnation.

Objective:To analyze the subsequent assisted pregnancy outcomes of recurrent implantation failure (RIF) and find out the key influencing factors.Methods:A case-control study was conducted to analyze the clinical data of 640 patients who received embryo transfer assisted fertility in the Center for Reproductive Medicine of the First Affiliated Hospital of Zhengzhou University from January 2016 to June 2019 and were diagnosed with RIF and received subsequent assisted fertility treatment. The main outcome measures were the live birth rate and the time to pregnancy after diagnosis of RIF.Results:The live birth rate, the biochemical pregnancy rate, the clinical pregnancy rate and the abortion rate of the first cycle, the second cycle, the third and above cycle after a diagnosis of RIF were not significantly different (all P>0.05). The time to pregnancy after diagnosis of RIF of 344 patients who achieved live births was 5.00(3.13, 8.52) months. After adjusting for confounding factors by using multivariate logistic regression, the results showed that the cumulative live birth probability of blastocyst transfer was significantly higher than that of cleavage embryo transfer [ P=0.002, RR (95% CI)=1.492(1.158-1.923)]; the cumulative live birth probability of patients less than 35 years old was significantly higher than older patients (≥35 years old)[ P=0.013, RR (95% CI)=0.694(0.521-0.925)]; the cumulative live birth probability of patients with endometrial thickness ≥8 mm on the embyro transfer day was significantly higher than that of patients with endometrial thickness <8 mm [ P=0.016, RR (95% CI)=1.943(1.132-3.335)]; compared with patients with 0 [ P=0.001, RR (95% CI)=0.625(0.474-0.825)] or 2 and more [ P=0.003, RR (95% CI)=0.414(0.233-0.736)] biochemical pregnancy in the RIF cycles, the cumulative live birth probability of patients with history of only 1 biochemical pregnancy in the RIF cycles was significantly higher. Conclusion:The type of embryos transferred, age, endometrial thickness on the embyro transfer day and the history of biochemical pregnancy in the RIF cycles are independent factors for subsequent cumulative live birth probability in RIF patients. Blastocyst transfer should be selected as much as possible, and fertility treatment should be performed as soon as possible through reasonable cycle management, the history of only 1 biochemical pregnancy in the RIF cycles heralds a better live birth outcome in the subsequent cycles of RIF.
