OBJECTIVE: To observe the clinical efficacy of meridian sinew manipulation releasing technique combined with heat-sensitive moxibustion for simple obesity. METHODS: Twenty-nine patients with simple obesity were selected, on the basis of the conventional treatment, the patients were treated with meridian sinew manipulation releasing technique on the affected meridian sinews in the abdomen and lower limbs, about 30 min a time. After releasing, using the moxibustion sensation localization method in the abdominal regions with high heat-sensitivity frequency (including acupoints such as Zhongwan [CV12], Tianshu [ST25], Qihai [CV6], Guanyuan [CV4]), 2 heat-sensitive acupoints were selected for moxibustion and moxibustion was applied at each acupoint for 40 min, or until the heat-sensitive moxibustion sensation disappeared. The patients were treated once every other day for a total of 20 times. The weight, body mass index (BMI), body fat rate, waist circumference and hip circumference of the patients before and after treatment were observed, and the clinical efficacy was evaluated after treatment. RESULTS: After treatment, the weight, BMI, body fat rate, waist circumference and hip circumference of the patients were decreased compared with those before treatment (P<0.05). The total effective rate was 93.1% (27/29). CONCLUSION Meridian sinew manipulation releasing technique combined with heat-sensitive moxibustion can effectively treat simple obesity, the treatment from the perspective of meridian sinews provides a new idea and plan for simple obesity.

Objective:To investigate the effect of nuclear factor E2-related factor 2 (Nrf2) protein on ferroptosis in mice with sepsis-associated liver injury (SALI).Methods:The male Sprague-Dawley (SD) mice were divided into 6 groups according to the random number table method, with 6 mice in each group. The SALI model of mice was established by cecal ligation and puncture (CLP), and the Sham group was only treated with laparotomy. CLP+Fer-1 group, CLP+Erastin group, CLP+ML385 group and CLP+Curcumin group were intraperitoneally injected with iron death inhibitor Ferrostatin-1 (Fer-1) 10 mg·kg -1·d -1, iron death activator Erastin 20 mg·kg -1·d -1, Nrf2 inhibitor ML385 30 mg·kg -1·d -1 and Nrf2 activator Curcumin 100 mg·kg -1·d -1 after CLP, respectively; Sham group and CLP group were given normal saline 10 mg·kg -1·d -1, each group was administered continuously for 10 days. Ten days after operation, the serum and liver tissues of mice were collected to detect the levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in serum, and the levels of malondialdehyde (MDA), glutathione (GSH) and Fe 2+ in liver homogenate. The pathological changes of liver tissue were observed under light microscope after hematoxylin-eosin (HE) staining. The shape and length of mitochondria in liver cells were observed under transmission electron microscope. The protein expressions of Nrf2, glutathione peroxidase 4 (GPX4) and prostaglandin-endoperoxide synthase 2 (PTGS2) in liver tissue were detected by Western blotting. Results:Compared with Sham group, the serum levels of ALT and AST in the CLP group were significantly increased; histologically, the hepatic cord was disordered, the cells were swollen and necrotic, and the length of mitochondria was significantly shortened; the levels of MDA and Fe 2+ in liver tissue increased significantly, and the content of GSH decreased significantly; the protein expressions of Nrf2 and GPX4 in liver tissue decreased, and the protein expression of PTGS2 increased significantly. Compared with CLP group, the serum levels of ALT and AST in CLP+Fer-1 group and CLP+Curcumin group were significantly decreased [ALT (U/L): 80.65±19.44, 103.45±20.52 vs. 283.50±37.12, AST (U/L): 103.33±11.90, 127.33±15.79 vs. 288.67±36.82, all P < 0.05]; microscopically, the hepatic cord was irregular, the cells were slightly swollen, and the mitochondrial length was significantly increased (μm: 1.42±0.09, 1.43±0.21 vs. 1.07±0.25, both P < 0.05); the levels of MDA and Fe 2+ in liver tissue decreased significantly, and the content of GSH increased significantly [MDA (mol/g): 0.87±0.23, 1.85±0.43 vs. 4.47±0.95, Fe 2+ (μg/g): 63.80±7.15, 67.48±6.28 vs. 134.52±14.32, GSH (mol/g): 1.95±0.29, 1.95±0.45 vs. 0.55±0.29, all P < 0.05]; the protein expressions of Nrf2 and GPX4 in liver tissue were significantly increased, and the protein expression of PTGS2 was significantly decreased (Nrf2/GAPDH: 1.80±0.28, 2.10±0.43 vs. 0.70±0.24, GPX4/GAPDH: 0.80±0.06, 0.93±0.07 vs. 0.48±0.02, PTGS2/GAPDH: 0.76±0.05, 0.84±0.01 vs. 1.02±0.09, all P < 0.05). However, the results of the above indexes in the CLP+Erastin group and CLP+ML385 group were opposite, and the serum levels of ALT and AST were significantly increased [ALT (U/L): 344.52±40.79, 321.70±21.10 vs. 283.50±37.12, AST (U/L): 333.50±27.90, 333.00±16.67 vs. 288.67±36.82, all P < 0.05]; microscopically, the arrangement of hepatic cords was disordered, the cells were obviously swollen and necrotic, and the length of mitochondria was significantly shortened (μm: 0.78±0.13, 0.67±0.07 vs. 1.07±0.25, both P < 0.05); the levels of MDA and Fe 2+ in liver tissue increased significantly, and the content of GSH decreased significantly [MDA (mol/g): 5.92±1.06, 5.62±0.56 vs. 4.47±0.95, Fe 2+ (μg/g): 151.40±8.03, 151.88±8.68 vs. 134.52±14.32, GSH (mol/g): 0.25±0.08, 0.23±0.11 vs. 0.55±0.29, all P < 0.05]; the protein expressions of Nrf2 and GPX4 in liver tissue were significantly decreased, and the protein expression of PTGS2 was significantly increased (Nrf2/GAPDH: 0.46±0.09, 0.46±0.11 vs. 0.70±0.24, GPX4/GAPDH: 0.34±0.05, 0.40±0.01 vs. 0.48±0.02, PTGS2/GAPDH: 1.24±0.13, 1.16±0.11 vs. 1.02±0.09, all P < 0.05). Conclusion:CLP-induced SALI can lead to ferroptosis in mice hepatocytes, and Nrf2 protein in liver tissue can mediate SALI by regulating ferroptosis.

Objective To investigate the biomechanical effects of the medial protrusio technique on the acetabular cup in adult patients with developmental hip(DDH)after total hip arthroplasty.Methods The CT scanning data of bilateral hips from an adult patient with unilateral DDH were obtained further to develop a finite element model of the affected hemipelvis.The medial protrusio technique with various levels of medial protrusio was simulated,and the biomechanical differences between the medial protrusio and non-protrusio groups were evaluated.Results In the simulated pull-out test,the maximum anti-pull-out load strength of the non-protrusio group was 1 166 N.Compared with the non-protrusio group,the anti-pull-out load strength of the 4 mm and 8 mm medial protrusio groups increased by 45.8％and 57.1％,respectively.The peak micromotion at the cup-bone interface for the non-protrusio group was 166.4 μm in the standing phase of the gait cycle,and that of the 4 mm and 8 mm medial protrusio groups was decreased by 46.2％and 62.1％,respectively.Regarding the immediate stress distributions of periacetabular bone tissues following cup implantation,the differences between the groups were not significant.Under the loading condition of the standing phase,the non-protrusio group yielded the lowest average and peak stresses.The average stress increased with the level of medial protrusio,and the highest peak stress was observed in the 4 mm medial protrusio group.Conclusions The medial protrusio technique can improve the initial stability of the acetabular cup,and the initial stability is positively proportional to the protrusio level.However,owing to the concentration of marginal stress at the cup-bone interface,a minor medial protrusio cup with insufficient bone coverage might increase the risk of various prosthesis-related complications.

Objective:Non-alcoholic fatty liver disease(NAFLD)is a common metabolic disorder in overweight and obese children,and its etiology and pathogenesis remain unclear,lacking effective preventive and therapeutic measures.This study aims to explore the association between whole blood copper,zinc,calcium,magnesium and iron levels and NAFLD in overweight and obese children aged 6 to 17 years,providing a scientific basis for the prevention and intervention of early NAFLD in overweight and obese children. Methods:A cross-sectional study design was used to collect relevant data from overweight and obese children who visited the Hunan Children's Hospital from January 2019 to December 2021 through questionnaire surveys.Fasting blood samples were collected from the subjects,and various indicators such as blood glucose,blood lipid,and mineral elements were detected.All children were divided into an overweight group(n=400)and a NAFLD group(n=202).The NAFLD group was divided into 2 subgroups according to the ALT level:A non-alcoholic fatty liver(NAFL)group and a non-alcoholic steatohepatitis(NASH)group.Logistic regression analysis was used to analyze the association between minerals(copper,zinc,calcium,magnesium,and iron)and NAFLD,NAFL and NASH. Results:A total of 602 subjects were included,of whom 73.6%were male,with a median age of 10(9,11)years,and a body mass index(BMI)of 24.9(22.7,27.4)kg/m2.The intergroup comparison results showed that compared with the overweight group,the NAFLD group had higher levels of age,BMI,diastolic blood pressure(DBP),systolic blood pressure(SBP),triglyceride(TG),low density lipoprotein(LDL),alanine transaminase(ALT)and aspartate aminotransferase(AST),and lower level of high density lipoprotein(HDL).The NAFL group had higher levels of age,BMI,DBP,SBP,ALT,and AST,and lower levels of HDL compared with the overweight group.The levels of age,BMI,DBP,SBP,TG,LDL,ALT,and AST of NASH were higher than those in the overweight group,while the level of HDL was lower than that in overweight group(all P<0.017).After adjusting for a variety of confounders,the OR of NAFLD for the highest quantile of iron was 1.79(95%CI 1.07 to 3.00)compared to the lowest quantile,and no significant association was observed between copper,zinc,calcium,and magnesium,and NAFLD.The subgroup analysis of NAFLD showed that the OR for the highest quantile of iron in children with NAFL was 2.21(95%CI 1.26 to 3.88),while no significant association was observed between iron level and NASH.In addition,no significant associations were observed between copper,zinc,calcium,and magnesium levels and NAFL or NASH. Conclusion:High iron level increases the risk of NAFLD(more likely NAFL)in overweight and obese children,while copper,zinc,calcium,magnesium,and other elements are not associated with the risk of NAFLD in overweight and obese children.

To analyze the epidemiological characteristics of pulmonary tuberculosis (PTB) in Motuo County from 2012 to 2021 and provide evidence for the prevention and control of PTB. A total of 223 cases of PTB were reported from 2012 to 2021 in Motuo County, with an average annual reported incidence rate of 171.39/100 000. Joinpoint regression model analysis showed that the average decline rate was 9.2% (P<0.001) from 2012 to 2021. Among the various types of PTB patients reported from 2012 to 2021, there were 69 cases of etiologic-positive cases which increased from 28.57% to 52.63%. Results from the circular distribution methods showed that there was no obvious peak time of PTB in Motuo County. There was no statistical difference in the average annual incidence of PTB between different genders (χ²=0.108, P=0.743). Among all age groups, the 20-29 years group had the highest proportion (26.91%, 60/223). The Monpa ethnic group (153 cases, 68.61%) had the largest number of cases, followed by the Lhoba people (44 cases, 19.73%) and the Tibetan (22 cases, 9.87%). Farmers (168 cases, 75.34%) had the highest occupational composition ratio, followed by students (40 cases, 17.94%). The main detection methods of PTB were clinical consultation and transferring consultation. Overall, the incidence rate of PTB decreased from 2012 to 2021. The majority of PTB patients were young adults with high transmission risk. It is necessary to pay more attention to the key populations and strengthen the comprehensive prevention and control for reducing the risk of PTB.

OBJECTIVE: To explore the manifestations of jingjin (sinews/fascia) lesions and summarize their distribution rules in the patients with neck-type cervical spondylosis so as to provide the evidences for the development of clinical diagnosis and treatment scheme of acupuncture for cervical spondylosis. METHODS: A total of 120 patients with neck-type cervical spondylosis were collected. The meridian diagnostic method was used to examine the upper back of each patient, the manifestation category of jingjin lesions, locations and the affected muscle regions of twelve meridians were recorded. RESULTS: (1) The punctate lesions of jingjin were detected in 15 regions, and the highest frequency of lesion occurred in the region from the inner upper corner of the scapula to Quyuan (SI 13) (113 cases, 94.2% of lesion frequency). The lesion frequency of 10 regions was ≥50.0%. The punctate lesions were mainly distributed in the muscle regions of hand-shaoyang (349 cases) and foot-taiyang (333 cases). (2) The linear lesions of jingjin were detected in 10 regions, and the highest frequency of lesion occurred in the region from the inner upper corner of the scapula to Quyuan (SI 13) (77 cases, 64.2% of lesion frequency). The lesion frequency of 2 regions was ≥50.0%. The linear lesions occurred mainly in the muscle region of foot-taiyang (251 cases). (3) Eight regions were examined to be the planar lesions of jingjin, and the highest frequency of lesion was found in the site of Jianjing (GB 21) (84 cases, 70.0% of lesion frequency). The lesion frequency of 3 regions was ≥50.0%. The muscle region of foot-taiyang (260 cases) was predominated in the planar lesions. (4) The distribution of all of the punctate, linear and planar lesions of jingjin was analyzed statistically. It was found that 25 regions were involved and those with the high lesion frequency were distributed in the area from the inner upper corner of the scapula to Quyuan (SI 13), the sites of Jianjing (GB 21) and Dazhui (GV 14), transverse processes of C₃ to C₅ and the area from the lateral border of the scapula to the teres minor, separately. The muscle regions of foot-taiyang, hand-shaoyang and hand-yangming were involved in various kinds of jingjin lesions. CONCLUSION Jingjin lesions in patients with neck-type cervical spondylosis can be divided into three categories, namely, punctate, linear and planar lesions; of which, the punctate lesions are dominated. A majority of jingjin lesions is related to the muscle region of foot-taiyang, and the lesion frequency is higher compared with the lesions to the muscle regions of hand-shaoyang and hand-yangming. Jingjin lesions are commonly distributed in the area from the inner upper corner of the scapula to Quyuan (SI 13).
