Objective To longitudinally investigate the characteristics of postoperative weight changes in patients with esophageal cancer and analyze its influencing factors, which can provide certain guidance for nutritional intervention in patients with esophageal cancer. Methods Patients with esophageal cancer who underwent surgical treatment at the Sichuan Cancer Hospital from December 2020 to February 2022 were prospectively included. The general information questionnaire and body composition analyzer were used to longitudinally investigate the patients’ weight and body composition before surgery (T0), 1 month after surgery (T1), 3 months after surgery (T2) and 6 months after surgery (T3), and the change characteristics were analyzed. The generalized estimating equation was used to analyze the influencing factors for postoperative weight changes in patients with esophageal cancer. Results A total of 130 patients were enrolled, including 110 males and 20 females, aged 42-79 (63.33±8.16) years. The weight and body composition of patients with esophageal cancer showed a continuous slow downward trend within 6 months after surgery. The weight loss rate of patients at 1, 3, and 6 months after surgery was 5.10%, 7.76%, and 9.86%, respectively. The analysis results of the influencing factors for postoperative weight showed that patients with the following characteristics had more weight loss: female (β=−7.703, P=0.001), ≥60 years (β=−3.657, P=0.010), smoking (β=4.622, P=0.010), low tumor differentiation degree (β=4.314, P=0.039), and high frequency of eating (β=−3.400, P=0.008). Conclusion Weight loss is an important health problem for patients with esophageal cancer after surgery, and patients have a continuous downward trend in weight within 6 months after surgery. Medical staff should pay special attention to the patients who are female, ≥60 years, having smoking history and low tumor differentiation degree.

Purpose To investigate the diagnostic significance of modified lung ultrasound score(MPUS)for pediatric bacterial and viral pneumonia.Materials and Methods A total of 93 eligible children with suspected community-acquired pneumonia in Quanzhou Maternal and Child Care Hospital(Quanzhou Children’s Hospital)from December 2022 to June 2023 were elected as the study subjects.All these children received lung ultrasound and the MLUS was recorded according to the ultrasound manifestations of A line,B line and lung consolidation.According to the etiological results,the children were divided into a bacterial pneumonia group and a viral pneumonia group.According to disease severity,the children were divided into the mild group and the severe group.The MLUS was used to analyze the diagnostic significance of pediatric bacterial and viral pneumonia.Results The MLUS in the mild pneumonia group was 7(4,13)points and the MLUS in the severe pneumonia group was 20(14,30)points,and MLUS scores of pneumonia in the two groups were different(Z=-5.205,P<0.05).By drawing receiver operating characteristic curve,MLUS score of 14.5 was used as the cut-off point,the sensitivity for diagnosing severe pneumonia was 75.9%,the specificity was 82.8%.Area under the curve was 0.838.There was no significant differences in MLUS of 8.00(4.00,16.00)between the bacterial pneumonia group and 13.00(7.00,21.75)between the viral pneumonia group(Z=-1.981,P>0.05).The MLUS of 10.00(5.25,17.75)in the mild bacterial pneumonia group and 5.00(4.00,9.50)in the mild viral pneumonia group were significantly different(Z=-3.403,P<0.05).There was no significant differences in MLUS between the severe bacterial pneumonia group and the severe viral pneumonia group(t=0.017,P>0.05).In mild pneumonia,the cut-off value for the modified lung ultrasound score of 10.5 predicted moderate diagnostic efficacy of mild bacterial pneumonia,the area under the curve was 0.747,sensitivity was 50%and specificity was 87.5%.Large-area lung consolidation was more common in the bacterial pneumonia group than in the viral pneumonia group(χ2=8.360,P<0.05).Conclusion The modified lung ultrasound score can effectively evaluate the severity of pediatric bacterial pneumonia and viral pneumonia.For the identification of the two,MLUS may be a certain guiding significance.

ObjectiveTo determine the syndrome of a rat model of follicular dysplasia induced by Tripterygium glycosides based on prescriptions and investigate the mechanism of traditional Chinese medicine intervention via the adenosine monophosphate-activated protein kinase （AMPK）/mammalian target of rapamycin （mTOR）/hypoxia-inducible factor-1 （HIF-1）/vascular endothelial growth factor （VEGF） pathway. MethodForty-eight rats with regular estrous cycles were randomly assigned into a normal group （n=8） and a modeling group （n=40）. The rats in the modeling group were administrated with Tripterygium glycoside suspension （75 mL·kg^-1） by gavage for 30 days. The modeled rats were assigned into model， Siwutang （3.69 g·kg^-1）， Youguiyin （3.11 g·kg^-1）， Zuoguiyin （7.29 g·kg^-1）， and Guishenwan （10.35 g·kg^-1） groups， with 8 rats in each group. The drug intervention lasted for 14 days. The changes of estrous cycle were detected by Pap staining， and a stereoscope was used to observe the morphology of the ovarian tissue. Hematoxylin-eosin staining was employed to observe the pathological changes and follicle count in the ovarian tissue. Enzyme-related immunosorbent assay （ELISA） was used to measure the levels of follicle-stimulating hormone （FSH）， luteinizing hormone （LH）， and estradiol （E₂） in the serum. Real-time fluorescence quantitative polymerase chain reaction and Western blot were employed to determine the mRNA and protein levels， respectively， of AMPK， mTOR， HIF-1， and VEGF in the ovarian tissue. ResultCompared with the normal group， the model group had a disordered estrous cycle， reduced secondary and mature follicles， increased atretic follicles， elevated FSH and LH levels， lowered E₂ level， up-regulated mRNA and protein levels of AMPK， and down-regulated mRNA and protein levels of mTOR， HIF-1， and VEGF （P<0.01）. Compared with the model group， Guishenwan increased secondary and mature follicles， decreased atretic follicles， lowered the FSH and LH levels， elevated the E₂ level， down-regulated the mRNA and protein levels of AMPK， and up-regulated the mRNA and protein levels of mTOR， HIF-1， and VEGF （P<0.01）. Compared with Guishenwan group， Siwutang， Youguiyin， and Zuoguiyin decreased mature follicles， increased atretic follicles （P<0.01）， elevated the LH （P<0.01） and FSH （P<0.05） levels， and lowered the E₂ level （P<0.05）. In addition， Youguiyin up-regulated the protein level of AMPK （P<0.05） and down-regulated the mRNA levels of mTOR and HIF-1 （P<0.01） as well as the mRNA and protein levels of VEGF （P<0.01）. Siwutang down-regulated the mRNA levels of mTOR and HIF-1 as well as the mRNA and protein levels of VEGF （P<0.05）. Zuoguiyin down-regulated the mRNA level of mTOR and the protein and mRNA levels of VEGF （P<0.05）. ConclusionGuishenwan may improve the ovarian function and promote follicle maturation in a rat model of follicular dysplasia by inhibiting the AMPK/mTOR/HIF-1/VEGF pathway， with the therapeutic effect superior to Zuoguiyin， Youguiyin， and Siwutang. It was hypothesized that this model presented the syndrome of kidney-essence deficiency.

Objective:To investigate the clinical efficacy of the vascularised semi-split fibular flap with lateral approach in ankle fusion.Methods:A total of 54 patients who underwent ankle fusion through the lateral menstrual approach by the Department of Trauma and Micro Orthopaedics, Zhongnan Hospital of Wuhan University from June 2015 to December 2020 was retrospectively analysed. Of the 54 patients, 27 patients who underwent ankle fusion with a semi-split fibular flap carrying blood supply were assigned to the fibular flap group, while other 27 patients who had ankle fusion with lateral plate were assigned to the plate group. The ankle fusions for both groups were performed by the same surgical team. The clinical efficacy of the 2 groups was evaluated by the success rate of bone fusion, the American Orthopedic Foot and Ankle Surgery(AOFAS) Ankle-Hindfoot Score System, and the Visual analog score(VAS). All the patients entered the postoperative follow-up at outpatient clinic.Results:The follow-up lasted for 12-24 months, with an average of 15 months. At 6 months after surgery, 24 patients in the fibular flap group achieved osseous union with 88.9% in the success rate of bone fusion. While 17 patients in the plate group achieved osseous union, with the success rate of bone fusion at 63.0%. There was a statistically significant difference between the groups( P<0.05). At 1 year after surgery, all 27 patients in the fibular flap group achieved bony union, with a 100% of the success rate of bone fusion, while 23 patients in the plate group achieved bony union at a 85.2% success rate of bone fusion, with 4 patients failed to heal. The difference was statistically significant( P<0.05). The AOFAS scores of the fibular flap group were 41.3±12.0, 65.6±5.6, and 79.1±7.0 before operation, at 6 months after operation and 1 year after operation, respectively, while the scores for the plate group at the same time were 40.8±11.3, 64.5±4.1 and 69.3±7.2. There was no significant difference in the scores between the groups before surgery and at 6 months after the operation ( P>0.05). The scores at 1 year after surgery in the fibular flap group was significantly higher than the plate group, and there was a statistically significant difference( P<0.05). The preoperative VAS score in the fibular flap group was 7.6±1.3, while it was 7.5±1.1 in the plate group. There was no significant difference between the groups in VAS score( P>0.05). However, the VAS score at 1 year after surgery was found at 1.8±0.9 in the plate group, and 1.9±0.8 in the fibular flap group and the difference between groups was statistically significant( P<0.05). Conclusion:The surgical procedure of semi-split fibular flap through the lateral approach has lower complications and higher success rate in ankle fusion in comparison with those of the fusion with lateral plate. Thus, further clinical investigations can be considered.

Objective:To establish a method of serum detection by Raman spectroscopy for the diagnosis of gastric cancer.Methods:Between April and November 2019, 110 patients with gastric cancer [73 males, 37 females, age (57.4±10.3) years] and 74 patients with colorectal cancer [48 males and 26 females, aged (58.3±12.2) years] were collected at the First Affiliated Hospital of Army Military Medical University, along with 100 healthy subjects [59 males and 41 females, aged (55.6±10.61) years] during the same period. Fasting venous blood serum samples were collected from the subjects. A Raman spectrometer XploRA PLUS was used in this experiment, with an excitation light source of 532 nm, a field of view of 100 times, and a spectrum range of 200-2 000 cm -1, etc. The serum samples were detected by nondestructive and non-contact rapid detection, and the Raman spectra of serum samples were collected. Using the Raman spectrum acquisition and processing supporting software LabSpec6 to smooth, baseline, and normalize the obtained Raman spectrum. Multivariate statistical analysis software SIMCA14.1 were applied to import and analyze the obtained Raman spectrum data by principal component analysis (PCA), orthogonal partial least squares discriminant analysis (OPLS-DA), and other methods for statistical analysis. An operating characteristic curve (ROC) was constructed to evaluate the model analysis effect between serum samples of healthy people and those with gastric cancer. Serum samples from the colorectal cancer group were used to verify the reliability of the model. Results:Six Raman peaks with good repeatability were detected in serum samples in health and gastric cancer group, and peaks were located at 1 001.17, 1 154.63, 1 337.89, 1 446.85, 1 515.33, and 1 658.34 cm -1, respectively. Raman intensities at six Raman peaks were significantly different between healthy and gastric cancer groups. At the displacement of 1 001.17, 1 154.63, and 1 515.33 cm -1, the Raman intensity in the healthy group was higher than that in the gastric cancer group. At 1 337.89, 1 446.85, and 1 658.34 cm -1 displacement, the Raman intensity of the gastric cancer group was higher than that of the healthy group. An OPLS-DA model was constructed to analyze the serum samples of the healthy group and the gastric cancer group. In the model, R 2 is the fitting power, and Q 2 is the predictive ability. The closer the values of R 2 and Q 2 are to 1, the better the performance of the model, and the obtained model's R 2X(cum)=0.809, R 2Y(cum)=0.819, Q 2(cum)=0.758. ROC characteristic curve was drawn based on the OPLS-DA model. The area under the curve (AUC) of the gastric cancer group was 0.998. Six peaks with good repeatability were detected in the serum Raman spectra of gastric cancer stage Ⅰ, Ⅱ, Ⅲ, and Ⅳ, which were located at the displacement of 1 001.85, 1 155.07, 1 338.36, 1 445.75, 1 515.92, and 1 657.68 cm -1, respectively, and at the displacement of 1 155.07 and 1 515.92 cm -1. The Raman intensity of gastric cancer stage Ⅳwas significantly higher than that of gastric cancer stages Ⅰ, Ⅱ, and Ⅲ. Conclusions:According to the model reliability verification, the healthy group, gastric cancer group and colorectal cancer group can also be effectively separated based on OPLS-DA results; it showed a good performance in separating the healthy group from the gastric cancer group. It is possible to detect serum samples from healthy people and gastric cancer patients unlabeled by combining Raman spectroscopy and the OPLS-DA method in multivariate statistics.

Objective To investigate the surgical outcomes of one-stage repair of the ankle fracture combined with grade Ⅲ injury to the lateral ligament.Methods From April 2015 to December 2017,23 patients with ankle fracture and lateral ligament injury were treated at Department of Traumatic Reconstruction Surgery/Foot and Ankle Surgery,Zhongnan Hospital.There were 15 males and 8 females,aged from 18 to 65 years (average,37.8 years).After intraoperative treatment of their fractures,22 ruptures of the ligamentous insertion were repaired with suture anchor and one rupture of the middle ligament with Internal Brace.Routine postoperative X-rays,physical examination and Sefton grading system were used to evaluate the stability of the ankle joint and the subtalar joint.The Karlsson-Peterson and American Orthopedic Foot and Ankle Society (AOFAS) scores were used to evaluate the function and pain of the ankle.Results The follow-up for this cohort ranged from 12 to 24 months (average,13.9 months).The bone union time ranged from 6 to 24 weeks,averaging 10.1 weeks.There was no chronic instability of lateral ankle or subtalar joint in all the cases.Two cases developed osteochondral lesion of the medial talus which was treated with micro-fracture surgery one year after injury;one case suffered subtalar arthritis which was treated by subtalar arthrodesis 14 months after injury.Their Karlsson-Peterson scores averaged 84.6 points and AOFAS ankle-hindfoot scores 93.7 points with 19 excellent and 4 good cases.The Sefton grading system gave 9 cases of grade Ⅰ and 14 ones of grade Ⅱ.Conclusion One-stage repair of the ankle fracture combined with grade Ⅲ injury to the lateral ligament can lead to the stability of the ankle joint and the subtalar joint and improved function of the ankle.

Objective: To observe the influence of TRPV6 gene silence on SW480 colon cancer cell biological behavior, change in the in-tracellular concentration of calcium, as well as influence of 1,25 (OH)2D3CaCl2and CuCl2on SD rat colonic neoplasm models. Method: SW480 colon cancer cells were infected using lentivirus particles. TRPV6 protein and mRNA expression was detected using immunohistochemical tests, Western blot, and PCR. Moreover, the proliferation, metastasis, and apoptosis of SW480 colon cancer cells were detected through MTT assay and metastasis and apoptosis experiments, and the concentration of Ca2+in SW480 colon cancer cells was measured using high-speed ionic imaging. The SD rat colon cancer model was established based on DMH, and were assigned into experimental group (DMH group, 15) and intervention group (DMH+1,25 (OH)2D3group, DMH+CuCl2group) and control group, 10 in each group. The SD rat colon cancer model is established based on DMH, given 1,25(OH)2D3(37.5 nmol/kg) and CuCl2(375 μmol/kg) separately as intervention. The occurrence of colonic neoplasms and glandular cancers in each group of rats was observed, and Western blot was employed for detection of the TRPV6 protein expression. Results: After the transfection of SW480 colon cancer cells by TRPV6-RNAi, the expression of TRPV6 mRNA and protein decreased, intracellular concentration of Ca2+decreased, proliferation and metastasis rate of SW480 colon cancer cells decreased, and apoptosis rate of these cells increased. The differences between the groups with intervention and the blank control group and negative control group showed statistical significance (P<0.05). The colon cancer occurrence rate in the control group was 0, while that of the DMH+1,25 (OH)2D3 group, DMH group, and DMH+CuCl2were 100%, 84.62%, and 33.33%, respectively. The TRPV6 protein expression was detected in all groups, while DMH+1,25(OH)2D3group was observed to exhibit the highest level of expression, followed by the DMH group, DMH+CuCl2group, and control group. The differences were of statistical significance (P<0.05). Conclusions: The proliferation and metastasis of SW480 colon cancer cells can be prohibited by lowering the concentration of Ca2+in the cells. Thus, the apoptosis of the cells can be induced. 1,25 (OH)2D3can help improve the expression of TRPV6 protein in experimental rat colon tissues and promote the formation of colon neoplasms. CuCl2can help lower the expression of TRPV6 protein in experimental rat colon tissues and prevent the formation of colon neoplasms.

Objective To investigate the clinical efficacy of three-stage Masquelet technique in the treatment of infective bone defects of foot and ankle.Methods A retrospective case series study was conducted on the clinical data of 19 patients with infective bone defects of foot and ankle admitted to Zhongnan Hospital of Wuhan University from December 2014 to October 2017.There were 15 males and four females,aged 18-68 years [(39.6 ± 12.3)years].Among the patients,16 patients were infected with bacteria and three patients were infected with Mycobacterium tuberculosis.The infection involved humeral end,talus and surrounding joints in 14 patients,internal hemorrhoids in two patients,midfoot and interphalangeal joints in one patient,and humerus and metatarsophalangeal joints in two.The operation included three stages:the first stage was thorough debridement,supplemented with negative pressure closed drainage (VSD) and continuous washing to clarify the pathogenic bacteria;the second stage was to fill the bone defect with targeted antibiotic bone cement to prevent or treat infection;in the third stage,after filling the antibiotic bone cement for 3 months with no sign of local wound infection,the bone cement was taken out,and the bone reconstruction operation was performed by means of internal fixation and bone grafting.The flap survival and wound healing were observed,and the time of fracture healing was recorded.The American Orthopaedic Foot and Ankle Society (AOFAS) score and the Visual Analogue Score (VAS) were used to evaluate the improvement of the function of the foot and ankle before operation and at the last follow-up,and the bone healing was evaluated according to the radiographic union scale in tibial (RUST) fractures.Results The patients were followed up for 9-12 months [(11.1 ±1.0) months].Two patients with soft tissue defects caused by preoperative infection and necrosis received posterior tibial artery perforator flap and anterolateral thigh flap repair in the second stage,and the flaps all survived.The postoperative bone healing time was 3 7 months [(3.5 ± 1.4)months].Nineteen patients underwent three-stage surgery,and the ankle and foot wound or sinus tract were all healed,with no infection recurrence during follow-up.At the last follow-up,the AOFAS score was improved significantly from preoperative (36.3 s-12.1) points to (71.4 ± 5.7) points (P ＜ 0.05).The VAS was decreased significantly from preoperative (5.3 ± 1.2) points to (1.4 ± 0.9) points (P ＜ 0.05).The RUST bone healing score at the last follow-up was 8-12 points [(10.2 ± 1.1) points].Conclusion In treating the infective bone defects of foot and ankle,the three-stage Masquelet technique can effectively control infection,facilitate wound healing,promote bone union,and improve foot and ankle function.
