Objective:To explore the speech features of female patients with anhedonic depression and their recognition of pleasure deficient symptoms.Methods:A total of 102 female depression patients who were hospitalized at Nanjing Brain Hospital from September 2020 to October 2021 were selected, including 62 anhedonic depression patients (anhedonic group) and 40 non-anhedonic depression patients (non-anhedonic group). A total of 50 female healthy controls were recruited during the same period.All participants were evaluated by the 17-item Hamilton depression scale (HAMD-17), Snaith-Hamilton pleasure scale (SHAPS), and the temporal experience of pleasure scale (TEPS), as well as voice acquisition.SPSS 23.0 software was used for data processing.Statistical analysis was conducted using one-way ANOVA, non-parametric tests, Logistic regression, and receiver operating characteristic curve.Results:Compared with the non-anhedonic group, the anhedonic group showed significant changes in 15 voice features(all P<0.05), including Mel-frequency cepstral coefficients, formant frequencies, intensity, and energy features.Among these features, Mel-frequency cepstral coefficients exhibited the highest accuracy in identifying anhedonic depression, with sensitivity of 47.5%, specificity of 91.9%, area under curve (AUC) of 0.751, 95% CI=0.686-0.866.Formant frequencies could identify female anhedonic depression, with a sensitivity of 90.0%, a specificity of 40.3%, an AUC of 0.647, and 95% CI=0.605-0.824.Energy features could identify anhedonic deficient depression, with a sensitivity of 60.0%, a specificity of 74.2%, an AUC of 0.679, and 95% CI=0.587-0.804.Intensity features could identify female anhedonic depression, with a sensitivity of 70.0%, a specificity of 58.1%, an AUC of 0.640, and 95% CI=0.554-0.769. Conclusion:Mel-frequency cepstral coefficients, formant frequencies, intensity features, and energy features may have specific changes in female patients with anhedonic depression.The Mel-frequency cepstral coefficients has the highest recognition accuracy for anhedonic symptoms in female depression patients, and is expected to become an objective evaluation index for female anhedonic depression.

Objective:To compare the efficacy and adverse events of induction chemotherapy combined with radiotherapy alone (IC+ RT) and induction chemotherapy combined with concurrent chemoradiotherapy (IC+ CCRT) for nasopharyngeal carcinoma in the era of intensity-modulated radiation therapy in this Meta-analysis.Methods:Retrospective or randomized controlled clinical studies published between 2010 and 2020 were searched from the Cochrane Library, PubMed, and Web of Science databases. The selected studies included nasopharyngeal carcinoma patients treated with IC+ CCRT or IC+ RT. STATA 12 software was used to combine the hazard ratio (HR), risk ratio (RR) and 95% confidence interval (CI), and random or fixed effect models were used for statistical analysis.Results:A total of 2483 patients from eight retrospective studies were included. The overall survival in the IC+ CCRT group was similar to that in the IC+ RT group ( HR=0.78, 95% CI: 0.58-1.04, P=0.091). However, the distant metastasis-free survival ( HR=0.56, 95% CI: 0.42-0.74, P<0.001) and progression-free survival ( HR=0.65, 95% CI: 0.54-0.77, P<0.001) were improved in the IC+ CCRT group compared with those in the IC+ RT group. In terms of adverse reactions, the acute adverse reactions in the IC+ CCRT group were increased significantly compared with those in the IC+ RT group. Conclusions:In the treatment of nasopharyngeal carcinoma, the overall survival of two treatment modes is similar, but the distant metastasis-free survival and progression-free survival in the IC+ CCRT group are better than those in the IC+ RT group, whereas the incidence of adverse reactions is also increased. IC+ CCRT may be a recommended treatment for nasopharyngeal carcinoma patients, but more research is needed.

Since December 2019, novel coronavirus pneumonia (NCP) has been reported in Wuhan, Hubei Province, and spreads rapidly to all through Hubei Province and even to the whole country. The virus is 2019 novel coronavirus (2019-nCoV), never been seen previously in human, but all the population is generally susceptible. The virus spreads through many ways and is highly infectious, which brings great difficulties to the prevention and control of NCP. Based on the needs of orthopedic trauma patients for emergency surgery and review of the latest NCP diagnosis and treatment strategy and the latest principles and principles of evidence-based medicine in traumatic orthopedics, the authors put forward this expert consensus to systematically standardize the clinical pathway and protective measures of emergency surgery for orthopedic trauma patients during prevention and control of NCP and provide reference for the emergency surgical treatment of orthopedic trauma patients in hospitals at all levels.

Objective To compare 2 mini-invasive surgical treatments,Achillon versus sponge forceps,for acute Achilles tendon rupture.Methods Between December 2010 and January 2015,35 patients with acute Achilles tendon rupture were treated at our department.They were 32 males and 3 females,with an average age of 36.4 years (range,21 to 64 years).The interval between injury and operation was 1 to 13 days (average,3.2 days).Sixteen of them were treated by Achillon while 19 by sponge forceps.The 2 groups were compatible with no significant differences in general clinical data (P ＞ 0.05).Rehabilitation was carried out 4 weeks after immobilization with brace.American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scoring system was used to evaluate the function of the affected foot at the last follow-up.The 2 groups were compared in terms of surgery time,hospital stay,AOFAS score,decrease in leg circumference,complications and rerupture rate.Results All the patients were followed up for an average of 9.6 months (from 6 to 19 months).There were no significant differences between the Achillon and sponge forceps groups regarding average AOFAS score (91.8 ± 4.4 versus 93.2 ± 5.8),surgery time (38.3 ± 13.2 min versus 42.5 ± 9.8 min),hospital stay (3.9 ± 1.5 d versus 4.1 ± 1.6 d),or decrease in leg circumference (2.1 ±0.5 cm versus 2.3 ± 0.3 cm) (P ＞ 0.05).No re-ruptures or sural nerve lesion was observed in either group.One case of delayed wound healing occurred in each group.Conclusions Both Achillon and sponge forceps can lead to limited complications and a very low rate of re-rupture in surgical treatment of acute Achilles tendon rupture.Compared with the Achillon technique,sponge forceps may have the advantages of simplicity and lower cost.

Objective:To apply modified proximal femoral nail anti-rotation ( PFNA ) fixation tech-niques performed by percutaneous placement of guide wire combined with true lateral view and to make the procedures simpler.Methods:A retrospective study was used to analyze the clinical data of femoral intertrochanteric fractures cases, which were treated with conventional PFNA fixation or modified PFNA fixation performed by percutaneous placement guide wire combined with true lateral view in our hospital, from March, 2011 to May, 2014.In the study, 60 cases were followed for average 13 months.The oper-ation time, the amount of bleeding, the fluoroscopy time, postoperative radiographic measurements ( tip apex distance, TAD ) and hip function scores were analyzed.Results:In modified PFNA group, the amount of bleeding, the operation time and the fluoroscopy time were (70.5 ±12.5) min, (34.9 ±6.1) mL, ( 63.6 ±9.7 ) s respectively.In conventional PFNA group, they were ( 80.6 ±17.1 ) min, (47.8 ±6.7) mL, (68.5 ±8.7) s respectively.There were significant differences in the above respects between the two groups (P were 0.006, 0.013, and 0.022 respectively).There were no significant differences in TAD, fracture healing time, postoperative hip scores between the two groups (P>0.05). Conclusion:Fracture line is a natural entry point for some cases of femoral intertrochanteric fractures when we use proximal femoral nail anti-rotation to fix the fracture.Applying percutaneous insertion of the guide pin combined with true lateral view could reduce the operation time, amount of bleeding, and fluo-roscopy time significantly, make the procedures simpler and acquire satisfactory results .

Objective:To investigate the characteristics and perioperative management of hemophilia patients with fracture.Methods:Retrospectively, we analyzed 8 patients with hemophilia combined with fracture, who were admittted to our department from 2005 to 2013.Six patients were with hemophilia A and two with hemophilia B;Based on the severity of hemophilia, 2 cases were light, 3 moderate and 3 severe;Based on the location of fracture, 4 cases were femoral neck fractures, 1 femoral intertrochanteric fracture, 1 bilateral distal femur fractures, 1 tibiofibula fracture, and 1 humerus intercondylar fracture. Blood coagulation factor replacement therapy was conducted preoperatively, intraoperatively and postoper-atively, All the patients underwent closed or open reduction and internal fixation or joint replacement. Also, we analyzed the perioperative complications and observed whether the fracture healed.Results:The average age was 33.5 years (14 to 47 years); In 6 cases, fractures occurred at femur, accounting for 75%of all the fractures; Femoral neck fracture was treated by closed reduction and hollow screws fixation;Femoral intertrochanteric fracture, distal femur fracture, and tibiofibula fracture were treated by open reduction and internal fixation with plate;Humerus intercondylar fracture was treated by elbow joint replacement.Intraoperative bleeding was from 50 to 600 mL, an average of 262 mL;Perioperatively, the average use of FⅧ/activated prothrombin complex concentrates ( APCC) was 358 U/kg (125 to 554 U/kg) .Postoperatively, poor wound healing was observed in 2 patients, and the condition improved after symptomatic treatment; In patients with internal fixation, all the fractures united, and the average hea ling time was 14 weeks.No complications such as fixation loosening or rupture occurred after internal fixation.Conclusion:Hemophilia combined with fracture mainly occurred in the young, and the site of fracture was given priority to femur.With perfect preoperative preparation, on the basis of the replace-ment therapy, hemophilia combined with fractures was safe for surgical treatment, and postoperative frac-tures healing wasgood.But the risk of poor wound healing was high.

Objective To investigate the prognostic outcome of open reduction and internal fixation(ORIF)with radial head resection in treatment of comminuted radial head fractures so as to discuss the corresponding operation options.Methods A series of 23 patients with Mason type Ⅲ or Ⅳ radial head fractures were enrolled in the study including 11 males and 12 females.Eight patients(three with Mason type Ⅲ and five with Mason type Ⅳ)underwent radial head resection and 15(seven with Mason type Ⅲ and eight with Mason type Ⅳ)received open reduction and internal fixation including nail and plate fixation in eight and screw and K-wire fixation in seven.The outcomes were assessed in regard of range of motion,radiographic findings,visual analogous scale(VAS)of pain,patient satisfaction degree,disabilities of the arm,shoulder and hand score system(DASH)and the Broberg & Morrey elbow performance score system.Results The follow-up period ranged from 12 to 65 months(mean 35 months),which showed fracture healing in all patients,with no traumatic arthritis happened.The mean range of flexion and extension arc at the elbow of ORIF group and resection group was 132°and 79.4°(P＜0.01)and the patient satisfaction was 9.1 and 8.0(P ＜0.05)respectively.According to the Broberg & Money elbow performance score system,the score was average 93.9 in the ORIF group,with excellent result in nine patients,good in five and fair in one,while the score was average 80.6 in the resection group,with excellent result in two patients,good in two and fair in four.There was statistical difference between two groups(P ＜0.01).The DASH score of the ORIF and resection group was 2.9 and 18.1 respectively(P＜0.05).Conclusions ORIF has better elbow motion,elbow function,daily living and satisfactory outcomes than radial head resection and is recommended for treatment of Mason type Ⅲ or Ⅳ radial head fractures for repair of the radial head as far as possible.

Objective To assess the efficienty of operation in humeral intercondylar fractures by section, reposition, internal fixation by composition nail and replacement of elbow joint. Methods From January, 1999 to May, 2009, Forty-six cases of the humeral intercondylar fracture were treated with operation. Thirty-eight cases were followed for 17 months. Their affected elbow joint function were evaluated by Cassebaum rating system, patients treated with total elbow replacement evaluated by Mayo elbow score, DASH score additionally. Results According to Cassebaum rating system,there were 22 cases rated as excellent,eight cases rated as good,five cases rated as poor,three case rated as poor. The fineness rate is 78. 9% (30/38). Mayo score in patients with joint replacement ranged from 75.0 - 90. 0, averaged 84. 4 ± 1.7. DASH score ranged from 25.0 to 75.0,averaged 41. 1 ±0. 8. There was 1 case of superficial soft tissue nonhealing and 2 cases of ulna nerve symptoms. Myodynamia in elbow joint bend and stretch was Ⅳ in 1 cases. Conclusion It is a good method to treat the humeral intercondylar fracture with rational use of open reduction or elbow replacement according to fracture type and patient condition.

Objective To treat radial head fractures with open reduction and internal fixation, removal of the radial head and artificial joint replacement based on different fracture types to discuss the outcome of these methods and summarize optimal strategy for treatment of radial head fractures. Meth-ods A retrospective study was done on data of 47 patients with 48 radial head fractures treated in our de-partment from November 1999 to May 2008. Among them, nine patients were treated conservatively (all type Mason Ⅰ fractures), 28 treated with open reduction and internal fixation (one patient with type Ma-son Ⅰ fracture, 14 with type Mason Ⅱ and 13 with type Mason Ⅲ), eight with removal of radial head (three patients with type Mason Ⅲ fractures and five with type Ⅳ) and three with artificial joint replace-ment (all type Mason Ⅳ fractures). Results All patients were followed up for average 2.8 years (1-4.4 years). Two patients treated with artificial joint replacement were followed up for six months and three months respectively. According to the Mayo Elbow Performance Index, the excellence rate was 8/9 in conservative treatment, 82% (23/28) in open reduction and internal fixation, 6/8 in removal of the radial head and 3/3 in artificial joint replacement respectively. Conclusions The radial head fracture should be given anatomical reduction for early functional exercise. Conservative treatment can be used for type Mason Ⅰ fractures, open reduction and internal fixation for type Mason Ⅱ , type Mason Ⅲ fractures and part of type Mason Ⅳ fractures. The removal of radial head or mental prosthesis replacement are al-ternative for parte of type Mason Ⅳ fractures that can not attain stable fixation through open reduction and internal fixation.
