Objective:To investigate the efficacy of osteochondral fragment fixation using bioabsorbable pins for Hepple Ⅱ osteochondral lesions of the talus (OLT) in adolescents.Methods:Retrospective case analysis was used. The clinical data and follow-up results of 13 adolescent patients (13 feet) with Hepple Ⅱ OLT were all treated with osteochondral fragment fixation using bioabsorbable pins admitted to Shanghai Sixth People′s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January 2017 to December 2021 were retrospectively analyzed. There were 7 males and 6 females, with 13 right feet. The age was (14.85±2.23) years old, ranged from 12 to 18 years old. According to the American orthopedic foot and ankle society (AOFAS) ankle-hindfoot score, visual analogue scale (VAS) and SF-36 score before operation and at the last follow-up were used to evaluate the efficacy and function of the patients. Measurement data with normal distribution were represented as mean ± standard deviation( ± s), and the comparison between groups was conducted using the t-test; The mearsurement data with skewness distribution were expressed by M( Q1, Q3), and rank-sum test was used for inter-group comparison. Results:Thirteen adolescent patients (13 feet) with Hepple Ⅱ OLT underwent surgery successfully and were followed up for (25.54±9.95) months. All wounds healed by first intention, and no complications such as wound infection and delayed healing occurred. Preoperative AOFAS ankle-posterior foot score, VAS and SF-36 score were 58.62±3.55, 7.00 (6.50, 8.00) and 68.38±4.81, respectively. At the last follow-up, the scores were 97.38±2.73, 1.00 (0.00, 1.00), 91.15±4.28, respectively, and the results were significantly improved at the last follow-up, with the difference between the two groups statistically significant( P<0.05). Conclusion:Osteochondral fragment fixation using bioabsorbable pins which can promote cartilage repair, significantly improve symptoms, and achieve better clinical satisfaction with fewer complications, is a safe and effective surgical treatment option for Hepple Ⅱ OLT in adolescents with satisfactory short-term clinical outcomes.

A retrospective analysis of occupational pneumoconiosis in Zibo City from 1949 to 2021 / 中国职业医学

Objective: To analyze the base incidence, distribution characteristics, survival status and social security of occupational pneumoconiosis (hereinafter referred to as "pneumoconiosis") in Zibo City. Methods: The new pneumoconiosis patients in Zibo City from 1949 to 2021 were selected as the research subjects using a cross-sectional survey. Household survey or telephone follow-up were carried out, and the distribution characteristics, living conditions and social security situation were retrospectively analyzed. Results: A total of 8 910 patients with pneumoconiosis were investigated, and 96.0% of them were male. The stage Ⅰ pneumoconiosis patients accounted for 91.3%. From 1949 to 2021, the number of pneumoconiosis patients showed a stepwise upward trend with time. Most of the patients suffered from coal worker pneumoconiosis and silicosis, which accounted for 48.7% and 38.9%, respectively. The average age of onset was (52.7±11.4) years, and the average length of service exposed to dust was (21.1±9.4) years. The patients were concentrated in Zichuan District, Boshan District and Zhangdian District, that accounted for 87.8%. The industry distribution was mostly mining industry and manufacturing industry, accounting for 61.1% and 31.6% respectively. Among the 8 910 cases of pneumoconiosis, 543 cases were lost in follow-up. A total of 8 367 patients were followed-up, with a follow-up rate of 93.9%. The mortality rate of patients who completed follow-up was 50.5%, and the mortality rate decreased with the increase of the stage of pneumoconiosis (P<0.01). The rate of adoring social security in the 4 138 surviving patients was 98.4%. Conclusion: The situation of prevention and treatment of pneumoconiosis in Zibo City is challenging. It is necessary to strengthen the special control of dust hazards in mining and manufacturing industries in key areas such as Zichuan District, Boshan District and Zhangdian District.

Bone Grafting Can Promote the Prognosis of Displaced Femoral Neck Fractures: A Follow-up of the Clinical Significance of Bone Defects

Background@#Femoral neck fractures (FNFs) comprise a large proportion of osteoporotic fractures in Asia. However, the full range of prognostic variables that affect prognosis remains unclear. Here, we aimed to determine whether the severity of bone defects at the fracture site and other variables impact the prognosis of displaced FNFs. @*Methods@#We evaluated the incidence of FNF internal fixation failures at regular intervals after surgery in data collected retrospectively. Digital Imaging and Communications in Medicine (DICOM) magnetic resonance imaging data of the displaced FNFs of 204 patients (> 20 years old; mean age, 52.3 years; men, 55.4%) who underwent internal fixation were used to construct threedimensional (3D) virtual models of the femoral neck region. We calculated the position and volume of bone defect (VBD) using our independently developed algorithm and Mimics software. Each participant was followed up for at least 24 months; complications were noted and correlated with VBD and demographic and clinical variables. @*Results@#On the basis of VBD values calculated from virtual reduction models, 57 patients were categorized as having a mild defect, 100 as having a moderate defect, and 47 as having a severe defect. Age (p = 0.046) and VBD (p < 0.001) were significantly correlated with internal fixation failure. Multivariate analysis revealed that severe bone defects were associated with internal fixation failure (adjusted odds ratio [aOR], 23.073; 95% confidence interval [CI], 2.791–190.732) and complications (aOR, 8.945; 95% CI, 1.829–43.749). In patients with a severe defect, bone grafting was inversely associated with internal fixation failure (aOR, 0.022; 95% CI, 0.002–0.268) and complications (aOR, 0.023; 95% CI, 0.002–0.299). @*Conclusions@#Bone defect severity was associated with internal fixation failure and other complications. For young adults with large VBDs, bone grafting of the defect can reduce the risk of internal fixation failure. These results provide useful new quantitative information for precisely classifying displaced FNFs and guiding subsequent optimal treatments.

A new science promotion intervention improves bone health awareness in community-dwelling middle-aged and elderly people / 中华老年医学杂志

Objective:To implement an intervention with community-dwelling middle-aged and elderly people through a new science promotion approach, and to evaluate changes in the level of bone health awareness.Methods:From April 2017 to June 2017, 200 community-dwelling middle-aged and elderly people aged 50 years and over were randomly included.They were divided into the intervention group receiving a new science promotion intervention(n=100, with 50 males and 50 females)and the control group(n=100, with 50 males and 50 females). Baseline and follow-up assessments of bone health awareness were performed before and after the one-year intervention.A questionnaire survey on preferences for different types of science promotion articles in WeChat accounts was conducted.Differences in scores for intervention effects before and after intervention were compared between the two groups.Potential influencing factors for the scale score were examined by a multi-factor analysis.Results:After one year of intervention, scores for intervention effects were higher in the intervention group than in the control group( P<0.001). In the intervention group, scores were higher after intervention than before intervention( P<0.001). In the control group, scores after follow-up were slightly higher than those at baseline(29.4±11.4 vs.27.9±10.1, P<0.001). The increase in scores before and after intervention was greater in the intervention group than in the control group( P<0.001). Baseline score, group designation, history of drinking and diabetes impacted the scores in middle-aged and elderly women, while other factors did not.Most middle-aged and older people preferred texts illustrated with pictures, and older people were more receptive to videos. Conclusions:The new science promotion method is beneficial to bone health management, can improve bone health awareness in middle-aged and elderly people.

A multicenter cross-sectional study on chronic critical illness and surgery-related chronic critical illness in China / 中华胃肠外科杂志

Objective@#To understand the prevalence, diagnosis and treatment of chronic critical illness (CCI) in China.@*Methods@#The clinical data of 472 adult patients admitted to ICU in 53 hospitals, including basic information, disease-related data, nutrition program, etc., were collected on May 10, 2019, by means of multi-center cross-sectional study. If surgical intervention was needed or the occurrence of the disease was directly related to the surgery, ICU patients were regarded as surgical ICU cases (n=211). In this study, the diagnostic criteria for CCI were: (1) admission to ICU >14 days;(2) combined with persistent organ dysfunction. The prevalence,distribution and treatment of CCI and surgery-related CCI were recorded and analyzed. The Mann-Whitney U test, chi-square test or Fisher exact test were used for comparative analysis.@*Results@#Among the 472 ICU patients from 53 hospitals, 326 were male (69.1%) and 146 were female (30.9%). The prevalence of CCI was 30.7% (145/472). Among 211 surgery-related ICU patients, 57 developed CCI with a prevalence of 27.0%. As compared to non-CCI patients, higher APACHE II score [median (IQR) 13.5 (10.0, 18.3) vs. 11.0 (7.0, 16.0), U=2970.000, P=0.007], higher Charlson comorbidity index [median (IQR) 4.0 (2.0, 7.0) vs. 3.0 (1.0, 5.0), U= 3570.000, P=0.036] and higher ratio of breath dysfunction [68.4% (39/57) vs. 48.1% (74/154), χ2=6.939, P=0.008] and renal dysfunction [42.1% (24/57) vs. 18.2% (28/154), χ2=12.821, P<0.001] were found in surgery-related CCI patients. While SOFA score, Glasgow coma score and other visceral function were not significantly different between surgery-related CCI and non-CCI patients (all P>0.05). NUTRIC score showed that surgery-related CCI patients had higher nutritional risk [43.9% (25/57) vs. 26.6%(41/154), U=5.750, P=0.016] and higher ratio of mechanical ventilation [66.7% (38/57) vs. 52.3% (79/154), χ2=3.977, P=0.046] than non-CCI patients. On the survey day, the daily caloric requirements of 50.2% (106/211) of surgery-related ICU patients were calculated according to the standard adult caloric intake index (104.6 to 125.5 kJ·kg-1·d-1, 1 kJ=0.239 kcal), and the daily caloric requirements of 46.4% (98/211) of patients were calculated by physicians according to the severity of the patient′s condition. 60.2% (127/211) of nutritional support therapy was enteral nutrition (including a combination of enteral and parenteral nutrition), while the remaining patients received parenteral nutrition (24.6%, 52/211), simple glucose infusion (9.0%, 19/211), or oral diet (6.2%, 13/211). The target calorie of CCI group was 104.6 (87.9, 125.5) kJ·kg-1·d-1, and the actual calorie intake accounted for 0.98 (0.80, 1.00) of the target calory. In the non-CCI group, the target calorie was 104.6 (87.9, 125.5) kJ·kg-1·d-1, and the actual calorie consumed accounted for 0.91 (0.66, 1.00) of the target calorie. There was no statistically significant difference between two groups (P=0.248, P=0.150).@*Conclusion@#The prevalence of CCI and surgery-related CCI in ICU is high, along with severe complications, respiratory and renal dysfunction and mechanical ventilation. Surgical patients admitted to ICU are at high nutritional risk, and active and correct nutritional support is essential for such patients.

Surgical site infection following abdominal surgery in China: a multicenter cross-sectional study / 中华胃肠外科杂志

OBJECTIVE@#To determine the incidence of surgical site infection (SSI) after abdominal surgery and to further evaluate the related risk factors of SSI in China.@*METHODS@#The multicenter cross-sectional study collected clinical data of all adult patients who underwent abdominal surgery from May 1, 2018 to May 31, 2018 in 30 domestic hospitals, including basic information, perioperative parameters, and incisional microbial culture results. The primary outcome was the incidence of SSI within postoperative 30 days. SSI was classified into superficial incision infection, deep incision infection, and organ/gap infection according to the US Centers for Disease Control and Prevention (CDC) criteria. The secondary outcome variables were ICU stay, postoperative hospital stay, total hospital stay, 30-day mortality and treatment costs. Multivariate logistic regression was used to analyze the risk factors of SSI.@*RESULTS@#A total of 1666 patients were enrolled in the study, including 263 cases of East War Zone Hospital of PLA, 140 cases of Affiliated Hospital of Qingdao University, 108 cases of The First Affiliated Hospital of Nanchang University, 87 cases of Central War Zone Hospital of PLA, 77 cases of West China Hospital, 74 cases of Guangdong General Hospital, 71 cases of Chenzhou First People's Hospital, 71 cases of Zigong First People's Hospital, 64 cases of Zhangjiagang First People's Hospital, 56 cases of Nanyang City Central Hospital, 56 cases of Lanzhou General Hospital of Lanzhou Military Command, 56 cases of Shandong Provincial Hospital, 52 cases of Shangqiu First People's Hospital, 52 cases of People's Hospital of Xinjiang Uygur Autonomous Region, 48 cases of The Second Xiangya Hospital of Central South University, 48 cases of Chinese PLA General Hospital, 44 cases of Affiliated Hospital of Xuzhou Medical University, 38 cases of Hunan Province People's Hospital, 36 cases of Dongguan Kanghua Hospital, 30 cases of Shaoxing Central Hospital, 30 cases of Northern Jiangsu People's Hospital, 29 vases of The First Affiliated Hospital of Zhengzhou University, 27 cases of General Hospital of Tianjin Medical University, 22 cases of Zigong Fourth People's Hospital, 21 cases of The Second Hospital of University of South China, 18 cases of Tongji Hospital, 15 cases of Nanchong Central Hospital, 12 cases of The 901th Hospital of PLA, 11 cases of Hunan Cancer Hospital, 10 cases of Lanzhou University Second Hospital. There were 1019 males and 647 females with mean age of (56.5±15.3) years old. SSI occurred in 80 patients (4.8%) after operation, including 39 cases of superficial incision infection, 16 cases of deep incision infection, and 25 cases of organ/interstitial infection. Escherichia coli was the main pathogen of SSI, and the positive rate was 32.5% (26/80). Compared with patients without SSI, those with SSI had significantly higher ICU occupancy rate [38.8%(31/80) vs. 13.9%(220/1586), P<0.001], postoperative hospital stay (median 17 days vs. 7 days, P<0.001) and total hospital stay (median 22 days vs. 13 days, P<0.001), and significantly higher cost of treatment (median 75 000 yuan vs. 44 000 yuan, P<0.001). Multivariate analysis showed that male rise(OR=2.110, 95%CI:1.175-3.791, P=0.012), preoperative blood glucose level rise(OR=1.100, 95%CI: 1.012-1.197, P=0.026), operative time (OR=1.006, 95%CI:1.003-1.009, P<0.001) and surgical incision grade (clean-contaminated incision:OR=10.207, 95%CI:1.369-76.120, P=0.023; contaminated incision: OR=10.617, 95%CI:1.298-86.865, P=0.028; infection incision: OR=20.173, 95%CI:1.768-230.121, P=0.016) were risk factors for SSI; and laparoscopic surgery (OR=0.348, 95%CI:0.192-0.631, P=0.001) and mechanical bowel preparation(OR=0.441,95%CI:0.221-0.879, P=0.020) were protective factors for SSI.@*CONCLUSIONS@#The incidence of postoperative SSI in patients with abdominal surgery in China is 4.8%. SSI can significantly increase the medical burden of patients. Preoperative control of blood glucose and mechanical bowel preparation are important measures to prevent SSI.

The effects of ethanol on the hippocampal neural tissue development and kainite receptor expression in young mouse / 中国神经精神疾病杂志

Objectives To investigate the effects of ethanol on neural development and kainate receptor expression in young mice. Methods Fetal alcohol spectrum disorder model was established by administration of 20% ethanol solu?tion to 7-day-old Kunming mice and control animals received physiological saline (The number of treatment and control were 80 and 40, respectively ). Body weight and general biological features were observed every day. Morris water maze was used to test learning and memory ability. Fluoro-Jade B was used to examine neural cells 24 hours after treatment in additional thirty 7-day-old Kunming mice which were further divided into two groups:a treatment group receiving 20%ethanol solution (n=15) and a control group receiving physiological saline (n=15). The development of neural cells and expression levels of kainite receptors were examined by using immunofluorescence staining. Results The body weight was significantly lighter in treatment group than in control group(control:21.13 ± 1.72g,treatment:13.96 ± 2.98g,P<0.05). Morris test showed that model group had longer latency than control group to find hidden platform(control:21.05± 5.31s,treatment:34.15±3.26s,P<0.05). Spatial probe test revealed that the number of passing through the platform were significantly smaller in model group than in control group(control:2.70 ± 1.25 times,treatment:0.93 ± 0.80 times,P<0.05). Astrocyte development anomaly was evident after ethanol treatment for 7 days. The expression levels of kainite re?ceptor GluR-6 and KA2 were up-regulated in the CA region of the hippocampus after ethanol treatment for 7 days. Con?clusion Kainite receptor GluR-6 and KA2 in CA region of the hippocampus may contribute to ethanol-induced hippo?campal neural development anomaly.

Role of tetramethylpyrazine in protection of homocysteine-induced hippocampal neural apoptosis in mice / 实用医学杂志

Objective To explore the role of tetramethylpyrazine (TMP) in protection of homocysteine (HCY)-induced apoptosis of hippocampal neurons in mice. Methods One hundred healthy adult Kunming mice of clean grade were randomly divided into 5 groups, 20 for each group. HCY was injected into lateral ventricle using stereotaxic technique. FJB staining was used to detect neural apoptosis and the Morris water maze test was applied to assess memory and cognitive abilities. Results FJB staining showed that apoptosis of hippocampal neurons in the mice treated with TMP at different doses decreased significantly as compared with that in HCY group, especially at a dose of 20 g/L. Conclusions TMP can alleviate HCY-induced damage of the hippocampal neurons in mice and improve memory and cognitive functions, which suggests TMP has a potential clinical value in prevention and treatment of Alzheimer′s disease.

Analysis of clinical effectiveness and complications of different internal fixation treatment for intertrochanteric femoral fractures / 中国医师进修杂志

Objective To investigate the clinical effectiveness of dynamic hip screw (DHS) internal fixation and proximal femoral nail (PFN) internal fixation for intertrochanteric femoral fractures.Methods One hundred and sixty-five patients with intertrochanteric femoral fractures were randomly divided into 2 groups,85 patients were in DHS group and 80 patients were in PFN group.The clinical effectiveness,index in operative procedure and complications were compared between two groups.Results The fine rate of DHS group and PFN group was 75.3％(64/85 ) and 83.8％( 67/80 ) (P ＞ 0.05 ).The indexes of function recover time,fracture healing time,amount of bleeding in operation,operation time in PFN group were significant lower than those in DHS group [(54.3 ± 11.7 ) d vs.(92.6 ± 10.5 ) d,(63.8 ± 12.2) d vs.(71.3 ± 10.6) d,(453.3 ± 50.7) ml vs.(627.5 ± 46.8) ml,(77.9 ± 25.2) min vs.( 115.7 ± 32.8) min](P＜0.05 ).The rate of short-term complications was 16.2％ (13/80) in PFN group,and 12.9 ％ ( 11/85 ) in DHS group(P ＞ 0.05 ).The rate of long-term complications was 1.2％( 1/80 ) in PEN group and 4.7％(4/85 ) in plts group (P ＜ 0.05).Conclusions As the treatment of intertrochanteric femoral fractures,PFN internal fixation has less bleeding and better efficacy,and can improve function recovery.PFN internal fixation is a better method for unstable femoral fracture.

Anatomical Variation of the Glissonean Pedicle of the Right Liver

PURPOSE: Many studies have been conducted to date regarding whether the right hepatic vein is the accurate border that divides the anterior and posterior section of the right liver. It has been reported that the Glisson pedicle of the right liver may be an anatomical variation that does not have a consistent morphology. We analyzed the relationship between the true borders of the anterior and posterior sections, and the right hepatic vein, based on cadaver dissection and MD-CT image analysis of the anatomical variation of the Glisson pedicle of the right liver. METHODS: Sixteen cadaver livers were available for dissection from the Department of Anatomy, and pre-operative MD-CTs of 20 donor livers who underwent living donor liver transplantation prior to December 2009, were obtained. We analyzed the 3D-relationship between the branches of the Glisson pedicles and the right hepatic vein of the right liver. They were divided into 3 groups according to the sliding pattern of the branches of the Glisson pedicle origin. When all segmental branches of the anterior pedicle arise from the main trunk of the anterior pedicle and all branches of posterior pedicle arise from the main trunk of posterior pedicle, it was designated as Group A (Normal Group). When a portion of the segmental branches of the anterior pedicle arises from the main trunk of the posterior pedicle, it was designated as Group B (Posterior dominant group). When a portion of the branches of the posterior pedicle arises from the main trunk of the anterior pedicle, it was designated as Group C (Anterior dominant group). RESULTS: Among the 16 cadaver liver dissections, 6 cases were in Group A, 5 in Group B, and 3 in Group C. Two cases were excluded from the study because the inferior right hepatic vein was the main draining vein of the right liver. The analysis of preoperative MD-CT of the 20 donor livers showed that there were 13, 4, and 3 patients in Groups A, B, and C, respectively. CONCLUSION: According to Couinaud's theory of anatomy, the right hepatic vein serves as the border between the anterior and posterior sections of the right liver. But, due to the frequent anatomical variations, an adequate understanding of the anatomical variations of the right Glisson pedicle should be necessary for liver surgery.

Concurrently, another 19 patients with the same diagnosis and approximately the same clinical features as the abovementioned 18 cases, as the control group, were treated by open extensive total uterectomy combined with pelvic lymphadenectomy. The operation time, intraoperative blood loss, postoperative recovery and complications of two groups were compared. Results No statistically significant differences were found on mean operation time between the laparoscopy group (272.8 min?80.3min) and open group (226.5 min?66.8min) (t=1.921,P=0.063). The number of removed lymph nodes was 15.6?5.1 in laparoscopy group and 16.8?5.7 in open group, without statistically significant differences (t=0.674,P=0.505). The recovery time of intestine functions in laparoscopy group (34.2 hours) was obviously shorter than that of open group (60.7 hours) (P

Analysis of operative patterns of 2272 laparoscopic hysterectomies / 中华妇产科杂志

Objective To evaluate the clinical efficacy of four different operative patterns of laparoscopic hysterectomy: laparoscopically assisted vaginal hysterectomy (LAVH), laparoscopically introfasial subtotal hysterectomy (LISH), laparoscopically subtotal hysterectomy (LSH) and laparoscopically total hysterectomy (LTH). Methods A retrospective analysis on 2272 cases of laparoscopic hysterectomy was carried out, including operating time, blood loss, complication and postoperative recovery. Results For the two groups which preserved cervix, LISH was performed in 1323 cases. The operating time was (91?21) min, blood loss (93?23) ml, complication rate 4.1%. LSH was conducted in 229 cases, with an operating time (70?18) min, blood loss (69?17) ml, complication rate 0. The difference between the two groups was significant (all P0.05). All patients recovered well postoperatively. Conclusions The four operative patterns are ideal for hysterectomy. Young patients should be operated with laparoscopic hysterectomy with preservation of cervix, old patients or patients with CIN should be operated with excision of cervix.
