OBJECTIVE: To observe the clinical efficacy of acupoint thread-embedding therapy of regulating governor vessel, dispersing lung, and suppressing reflux for gastroesophageal reflux cough (GERC). METHODS: A total of 120 GERC patients were randomly assigned to an observation group (60 cases, 1 case dropped out) and a control group (60 cases, 1 case was eliminated). The observation group received acupoint thread-embedding treatment at positive response points of governor vessel. If no such points were detected, the following acupoints were used: Dazhui (GV14), Fenghu (Extra), Shendao (GV11), Lingtai (GV10), and Zhiyang (GV9). Treatment was administered once every two weeks. The control group received oral rabeprazole enteric capsules at 20 mg twice daily. All the treatment was given for 6 weeks. Clinical outcomes were assessed using cough symptom score, reflux disease questionnaire (RDQ) score, and Leicester cough questionnaire (LCQ) score before and after treatment in the two groups. Clinical efficacy was also compared between the two groups. RESULTS: After treatment, both groups showed decreased cough symptom scores and the each item scores and total scores of RDQ (P<0.001), and increased LCQ scores (P<0.001) compare with those before treatment. The observation group exhibited lower cough symptom score and chest pain, reflux and total score of RDQ, and higher LCQ score compared to those in the control group (P<0.05). The total effective rate in the observation group was 94.9% (56/59), which was higher than 84.7% (50/59) in the control group (P<0.05). CONCLUSION Acupoint thread-embedding therapy of regulating governor vessel, dispersing lung, and suppressing reflux could effectively alleviate cough and reflux symptoms in patients with GERC and improve their quality of life.

OBJECTIVE: To investigate the effectiveness of three-dimentional (3D) printed personalized guide plate-assisted wrist arthroscopic repair for Palmer type ⅠB triangular fibrocartilage complex (TFCC) injury. METHODS: A retrospective analysis was conducted on the clinical data of 20 patients with Palmer type ⅠB TFCC injuries admitted between January 2023 and March 2024 who met the selection criteria. Among them, 13 were male and 7 were female; ages ranged from 23 to 35 years, with a mean age of 30.3 years. All patients had a history of trauma, 12 cases involved falls and 8 cases involved sprains. All patients demonstrated a positive "piano key sign". MRI revealed deep ulnar-side tears of the TFCC. Conservative treatment for 6 weeks yielded poor or no clinical improvement. The interval from injury to surgery ranged from 2 to 9 months, with a mean of 5.0 months. Patients underwent wrist arthroscopic repair assisted by 3D printed personalized guide plate. Functional recovery was assessed preoperatively and postoperatively using the visual analogue scale (VAS) score for pain, modified Mayo wrist score, and range of motion (ROM) measurements for wrist flexion-extension, ulnar-radial deviation, and pronation-supination. At last follow-up, MRI was performed to evaluate the healing of TFCC. RESULTS: All 20 patients underwent successful surgery without complications such as vascular or nerve injury, fracture, incisional infection, or joint stiffness. All patients were followed up 9-18 months (mean, 12.4 months). At last follow-up, patients demonstrated significant improvements in VAS scores, modified Mayo wrist scores, wrist flexion-extension ROM, ulnar-radial deviation ROM, and pronation-supination ROM compared to preoperative levels ( P<0.05). MRI at last follow-up showed preserved TFCC continuity, excellent healing, and secure fixation. CONCLUSION 3D-printed personalized guide plate significantly improve outcomes in wrist arthroscopic TFCC repair for Palmer type ⅠB injuries. They enable high-quality suturing, facilitate anatomical reconstruction, and markedly enhance wrist function.

Purpose To establish and evaluate a high-speed fragment-induced penetrating liver injury model in pigs assisted by portable ultrasound.Materials and Methods With the aid of portable ultrasound,the lower edge of the liver at the end of expiration and the lower edge of the right chest at the end of inspiration of 10 Landrace pigs were positioned on the body surface.Then the sighting line was traced to determine the direction of projection and the sighting point.High-speed(about 627 m/s)fragments were projected through an experimental ballistic gun to induce penetrating liver injury.Blood pressure,heart rate,respiratory rate,pulse oxygen saturation and other physiological indexes were measured 15 minutes before shooting and 20 minutes after shooting.20 minutes after injury,the liver injury and the degree of injury were examined by ultrasound.After injury,the liver injury and abdominal fluid accumulation were observed by on-site portable ultrasound,and the size of liver trauma,liver injury grade,abdominal fluid accumulation location and maximum depth were recorded.The degree of liver injury was evaluated by comparison with the gross pathological results.Results Nine out of ten pigs were successfully modeled.The success rate of penetrating liver injury induced by fragments was 90%(9/10),other organ injury in abdominal cavity was 22.22%(2/9),and diaphragm penetrating injury was 22.22%(2/9),which did not occur obvious hemopneumothorax.After injury,the systolic blood pressure,diastolic blood pressure,and pulse oxygen saturation of the pigs decreased[(132.44±12.65)mmHg vs.(103.33±33.43)mmHg,(96.44±12.27)mmHg vs.(70.89±24.21)mmHg,(89.44±8.49)%vs.(76.00±13.41)%;t=2.440,2.651,4.084,all P<0.05],and the heart rate increased[(94.00±17.39)times/min vs.(139.89±37.21)times/min;t=3.534,P<0.05].Within 20 minutes after modeling,portable ultrasound images showed that the liver injury was a patchy,heterogeneous,slightly strong echo area with clear and irregular boundary,and the continuity of the local liver capsule was interrupted.The ascites appeared in the abdominal cavity with the maximum depth of(4.16±1.35)cm.The American association for the surgery of trauma(AAST)liver injury grading of gross pathology after the animals were killed showed that there were 6 cases of grade Ⅱ and 3 cases of grade Ⅲ.Along the fragment projection direction,the short diameter measured by ultrasound was positively correlated with the depth of gross pathological laceration(r=0.945,P<0.001).Compared with the gross specimen,the accuracy rate of ultrasonic AAST grading of liver injury was 88.89%(8/9).Conclusion The model of high-speed fragment-induced liver injury in pigs assisted by portable ultrasound is accurate and stable,and portable ultrasound can effectively evaluate the penetrating liver injury,which provides a basis for the treatment of liver firearm injury.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.

Objective:To investigate the risk factors for 1-year survival rate in patients with spinal metastasis secondary to lung cancer.Methods:The data of 343 patients with spinal metastases secondary to lung cancer from January 2011 to December 2018 were retrospectively studied. There were 188 males (54.8%) and 155 females (45.2%) with an average age of 59.47±10.21 years old (range 23-91 years). The patients were divided into operation group (150 cases, 43.7%) and non operation group (193 cases, 56.3%). The demographics, types of primary tumor, non spinal metastasis, visceral metastasis, spinal metastasis and segments, pathological fractures of vertebra, Frankel classification, physical function status (Karnofsky performance scale, KPS), visual analogue score (VAS), the spinal instability neoplastic score (SINS) were recorded and analyzed. The impact of different treatments on the survival prognosis of patients with spinal metastasis was evaluated. The independent factors affecting survival in those patients were analyzed by Cox proportional hazards regression model.Results:The peak incidence of spinal metastases was found in the age group of 46-60 years (43.7%, 150/343). 38.5% (132/343) of the patients had pathological fractures of the involved vertebral body. 58.3% (200/343) of the patients had extraspinal bone metastasis. 36.2% (124/343) of the patients had visceral metastasis. Among the primary tumors, adenocarcinoma was the most common tpye (61.5%, 211/343), followed by large cell lung cancer (12.5%, 43/343), small cell lung cancer (6.4%, 22/343), squamous cell cancer (6.1%, 21/343) and mixed cell lung cancer (5.3%, 18/343). The type of lung cancer cells in about 8.2 (28/343) patients was unknown. Among the surgical patients, 21 patients underwent minimally invasive surgery (14.0%), 28 patients underwent simple decompression surgery (18.7%), 76 patients underwent separation surgery (50.7%), and 25 patients underwent radical surgery (16.6%). 59.3% (89/150) of the patients had a better neurological function than before surgery. The average survival time of all patients was 9.88 months with the median survival time of 8 (5,14) months. The survival rates were 62.1% (213/343), 30.0% (103/343), and 3.8% (13/343) at 6, 12, and 24 months, respectively. The average survival time of patients in the operation group was 10.24 months with the median survival time of 9 (5, 15) months, and the average survival time of patients in the non operation group was 9.41 months with the median survival time of 7 (5, 13) months with no significant difference between the groups (χ 2=0.300, P=0.584). Multivariate Cox proportional hazard regression model analysis showed that radiotherapy [ HR=1.913, 95% CI(1.471, 2.488), P<0.001], chemotherapy [ HR=1.313, 95% CI(1.040, 1.658), P=0.022], targeted drug therapy [ HR=1.683, 95% CI(1.221, 2.319), P=0.001], KPS [ HR=1.593, 95% CI(1.140, 2.225), P=0.006] and pathological type (non-small cell lung cancer) were independent factors affecting the 1-year survival rate of patients with spinal metastasis secondary to lung cancer [ HR=0.322, 95% CI(0.225, 0.460), P<0.001] with significant difference. Conclusion:Surgical treatment can improve both the neurological function and general status of patients with spinal metastasis. Treatments of radiotherapy, chemotherapy, and targeted drug therapy can significantly improve 1-year survival rate, while a KPS less than 50 points and a primary lung cancer other than adenocarcinoma were independent risk factors reducing 1-year survival rate.

Ferroptosis is a kind of programmed cell death, involves multi-molecular and multi-signaling pathways, and the core processes is iron overload and lipid peroxidation. It affects cancer, neurological disease, cardiovascular disease, digestive system disease, and many other diseases. While, ischemia-reperfusion injury is an extremely complex pathological process, including ischemia-reperfusion injury of the heart, brain, liver and kidney, etc., which often occurs in shock, organ surgery and organ transplantation, seriously affecting human health, and there is no effective radical treatment. However, ferroptosis is closely related to ischemia-reperfusion injury so that it is possible to find the prevention and treatment measures of ischemia-reperfusion injury by exploring the internal relationship between them. Therefore, the author tries to summarize the signaling pathways of ferroptosis, and explores the relationship between ferroptosis and ischemia-reperfusion injury of heart, brain, liver and kidney by moderating the ferroptosis targets properly to find the effective ways to treat cancer, improve inflammation and relieve other diseases.

Objective:To investigate the coverage of qualified iodized salt in catering service units where residents ate out in Shanxi Province, so as to provide a basis for taking targeted preventive measures timely and adjusting of intervention strategies scientifically, and to consolidate the achievements of eliminating iodine deficiency disorders (IDD) continuously.Methods:One prefecture level city from each of the five directions of east, west, south, north and middle in Shanxi Province in 2021 was selected. One mountainous county and one plain county were selected in each city. Each of the counties was divided into five sampled regions along five different geographic directions: east, west, south, north and middle. From each region, one town/street was selected randomly and then two canteens of enterprises and institutions (canteens), five medium-sized restaurants and five small restaurants were selected from each town/street. We investigated the basic information of catering service units, collected salt samples and then detected the iodine content of these salt samples. In addition, salt iodine testing data of county residents corresponding to catering service units in the 2021 iodine deficiency disorders monitoring were collected from the Shanxi Institute of Endemic Disease Prevention and Treatment, and compared with the survey results of catering service units.Results:A total of 660 salt samples were detected, the median value of salt iodine was 27.65 mg/kg, the coverage rate of iodized salt was 99.39%(656/660), and the coverage rate of qualified iodized salt was 90.76% (599/660). The median value of salt iodine was 26.70, 28.00 and 27.60 mg/kg in canteens, medium-sized restaurants and small restaurants, respectively, and the coverage rate of qualified iodized salt was 95.54% (107/112), 90.42% (236/261), and 89.20% (256/287), respectively. There was no significant difference in the coverage rate of qualified iodized salt among different types of catering service units (χ 2 = 3.92, P = 0.141). The median value of salt iodine was 28.00 and 27.20 mg/kg in mountainous counties and plain counties, respectively, and the coverage rate of qualified iodized salt was 88.67% (266/300) and 92.50% (333/360), respectively. There was no significant difference in the coverage rate of qualified iodized salt among the counties of different geographical types (χ 2 = 2.87, P = 0.090). The median value of salt iodine in catering service units and households was 27.65 and 23.50 mg/kg, respectively, and the coverage rate of qualified iodized salt was 90.76% and 95.91%, respectively. There was a statistically significant difference in the coverage rate of qualified iodized salt between catering service units and households (χ 2 = 31.19, P < 0.001). Conclusions:The coverage rate of qualified iodized salt in catering service units in Shanxi Province generally meets the national elimination standard (> 90%), but there are still some counties that do not meet the standard. The coverage rate of qualified iodized salt in small and medium-sized restaurants is also not optimistic. It is recommended to strengthen monitoring and supervision of edible salt in catering service units in the future.

Objective:To investigate the current situation of water-borne high iodine hazards in Shanxi Province and the implementation of prevention and control measures, providing a scientific basis for prevention and control of the high iodine hazards in the future.Methods:In 2020, a survey was conducted on iodine content of drinking water and water improvement situation in all high iodine administrative villages in 12 water-borne high iodine counties of 4 cities in Shanxi Province. In each monitoring county, five administrative villages were selected as monitoring villages using a systematic sampling method, sorted by the iodine content of the water in the administrative villages. Forty non-boarding students aged 8 - 10 from one primary school and 20 pregnant women were selected from each monitoring village. Household edible salt samples and one random urine sample were collected for salt iodine and urinary iodine content test. B-ultrasound method was used for thyroid examination in children.Results:A total of 297 high iodine administrative villages were surveyed on the drinking water situation of residents, including 268 villages with improved water and 29 villages without improved water, with a water improvement rate of 90.24%. The range of water iodine was 0.33 - 803.75 μg/L, and there were 159 villages with water iodine content > 100 μg/L. A total of 1 926 samples of household edible salt were tested, and the rate of non iodized salt was 62.20% (1 198/1 926); 1 704 urine samples from children and 222 urine samples from pregnant women were tested, with median urinary iodine contents of 426.2 and 318.9 μg/L, respectively. The 1 690 cases of thyroid gland in children were examined, with a goiter rate of 3.91% (66/1 690) and a nodule detection rate of 13.67% (231/1 690).Conclusions:Children's iodine nutrition in water-borne high iodine areas of Shanxi Province is at an iodine excess level, while pregnant women's iodine nutrition is at an iodine excess level. Efforts should be made to increase the popularization of non iodized salt and improve water quality to reduce iodine in areas with high iodine levels, in order to control the harm of high iodine in water sources as soon as possible.

Objective:To investigate the serum 25-hydroxyvitamin D [25(OH)D] level in patients with Graves' disease (GD) and its correlation with thyrotropin receptor antibody (TRAb) and bone metabolism markers.Methods:A total of 124 patients with newly diagnosed or relapsed GD were selected and divided into three groups according to serum 25(OH)D level, namely vitamin D deficiency group with 25(OH)D <12 μg/L, vitamin D insufficiency group with 25(OH)D of 12 to 20 μg/L, and vitamin D sufficiency group with 25(OH)D ≥ 20 μg/L. The levels of serum 25(OH)D, TRAb, type I procollagen N-terminal pro-peptide (PINP), type I collagen cross-linked C-terminal peptide (S-CTX), parathyroid hormone (PTH), total triiodothyronine (TT 3), total thyroxine (TT 4) and thyroid-stimulating hormone (TSH) were measured in all patients, and the differences of these biochemical indices were compared across groups. Oneway analysis of variance or Kruskal-Wallis test was used for comparison between groups, and Pearson or Spearman correlation analysis was applied for correlation test. Results:The levels of serum TT 3, TT 4, PINP, and S-CTX significantly increased ( P < 0.01) and the level of phosphorus (P) decreased ( P < 0.01) with the decreased vitamin D levels. The levels of PTH and calcium (Ca) were significantly lower in the vitamin D sufficiency group compared with the vitamin D insufficiency group and vitamin D deficiency group ( P < 0.01). Correlation analysis showed that serum 25(OH)D level was negatively correlated with the levels of TT 3, TT 4, PINP, S-CTX, PTH and Ca ( P < 0.01), and positively correlated with the levels of P and TSH ( P < 0.01). Conclusions:Decreased serum 25(OH)D level is closely related with increased bone turnover, PTH, and thyroid hormone levels in patients with GD, but not related with TRAb. Thyroid hormone levels have a certain predictive value regarding vitamin D deficiency in GD patients. It is necessary to monitor the vitamin D levels in patients with GD and provide vitamin D supplementation to reduce the incidence of osteoporosis, improve the effectiveness of antithyroid treatment and reduce the recurrence of GD.
