Objective:To evaluate the clinical efficacy of the treatment of boutonniere deformity by tenodesis of the bilateral slips of the flexor digitorum superficialis (FDS) tendon.Methods:From February 2021 to May 2022, the boutonniere deformity was retrospectively analyzed, by tenodesis of the bilateral slips of the FDS in the Department of Hand and Foot Microsurgery of Nanjing Jiangbei Hospital.During the operation, the lateral side of the bilateral FDS was split at the distal end separately. Then the two bundles were tunneled through the bone of the middle phalanx and weaved with the central band of the extensor tendon. The involved finger was stabilized in extension with splinting for 4 weeks after surgery. Extension and flexion of the proximal interphalangeal joint(PIPJ) of the finger should be gradually strengthened. Finger function was evaluated according to the total action movement (TAM) system of the American Association of Hand Surgeons.Results:A total of 7 patients (7 digits) were enrolled, including 5 males and 2 females, and the age ranged from 22 to 64 years old, with an average age of 42 years old. The injured included 1 index finger, 2 middle fingers, 2 ring fingers, and 2 little fingers. These patients were follow-up for 6 to 8 months with an average of 7 months. All wounds healed by primary intention. This operation can obtain the complete correction of the boutonniere deformity. The PIPJ was stable and capable of active flexion and straightness. The straightness of PIPJ and distal interphalangeal joint was improved. The mean active motion of the PIPJ of the affected finger was 92.4°, and the mean TAM of the affected finger was 271.3°. According to TAM system assessment criteria: excellent in 6 patients, good in 1 patient.Conclusion:It is a safe and effective new method for the correction of boutonniere deformity, which can be effectively treated with tenodesis of the bilateral slips of the FDS.

Objective:To discuss the clinical curative effect of the treatment of bundling bone fragment with figure-of-eight suture through double bone tunnels in the chronic bong mallet finger.Methods:A retrospective analysis was performed on patients with chronic bong mallet fingers who underwent surgery in the Department of Hand and Foot Microsurgery of Nanjing Jiangbei Hospital from May 2021 to February 2023. During the procedure, made into transverse double bone tunnels on the base of the distal phalanx with 0. 8 mm Kirschner wire, bundling bone fragment with figure-of-eight suture through double bone tunnels, then fixed with Kirschner wire elastic compression. Removal of the Kirschner wire 3 weeks after the procedure, the active flexion and extension range of the joints of the affected finger and the corresponding finger were measured at the last follow-up, then the range of motion (ROM) of the distal interphalangeal joint (DIPJ) and total action movement (TAM) of the fingers (affected and healthy finger) were recorded. The curative effects were evaluated according to the TAM system of the American Association of Hand Surgeons, including 4 grades: excellent, good, fair, and poor. SPSS 13. 0 software was used for statistical analysis of the data, and the measurement data conforming to normal distribution were expressed as Mean ± SD. The ROM of DIPJ and TAM of the affected finger were compared with the corresponding healthy finger 6 months after surgery by a paired sample t test. P<0. 05 indicates that the difference is statistically significant. Results:A total of 30 patients (30 digits) were enrolled, including 19 males and 11 females, and the age ranged from 18 to 62 years old, with an average age of 31 years old. The time from injury to operation was 24 to 65 days (mean of 35 days) . According to Wehbe and Schneider classification, there were 8 cases of type Ⅰa, 6 cases of type Ⅰb, 7 cases of type Ⅱa, 5 cases of type Ⅱb, 2 cases of type Ⅲa and 2 cases of type Ⅲb. All incisions healed well, the intraoperative blood loss was minimal, with no infection. All 30 cases were followed up for 6 to 7 months. All fractures were well aligned and healed, malformed fingers were completely corrected, and no needle tunnel infection or needle breakage were observed. At the last follow-up, the differences of the ROM of the DIPJ [ (30. 2±3. 5) °vs. (30. 4±3. 3) °, t=2. 57, P=0. 463] and the TAM [ (235. 3± 3. 6) ° vs. (237. 7± 4. 2) °, t=1. 78, P= 0. 247 ] between the affected and healthy fingers were not statistically significant. Finger function assessment: 27 cases were excellent, and 3 cases were good, and the excellent and good rate was 100%. Conclusion:Satisfactory therapeutic outcome for the treatment of chronic bong mallet finger deformity can be achieved by bundling bone fragment with figure-of-eight suture through double bone tunnels. It is an effective and practical method.

Objective:To explore the effect of the treatment of tendinous mallet finger deformity by the minimally invasive percutaneous quantitative suture technique eight times.Methods:A retrospective analysis was performed on patients with fresh tendinous mallet fingers who underwent surgery in the Department of Hand and Foot Microsurgery of Nanjing Jiangbei Hospital from April 2021 to April 2022. During the procedure, the extensor digitalis tendon in the zone Ⅰ was sutured percutaneous with 3-0 thread monofilament sutures in the "quantitative 8-stitch method" according to the pre-marked number sequence of 1 to 8, and fixed at the base of the distal phalanx via a constructed bone tunnel.

Objective:To evaluate correlation between left ventricular mechanical contraction synchrony and left ventricular systolic function by gated myocardial perfusion imaging(GMPI) using Cadmium-Zine-Telluride (CZT) SPECT.Methods:Three hundred and forty three consecutive patients( 232 males, 111 females, age (60.08±12.88) years) who underwent CZT SPECT GMPI in Shanxi Cardiovascular Hospital between January and August 2019 were retrospectively analyzed. The Emory cardiac toolbox was used to process the imaging data, and the left ventricular systolic synchrony parameters and systolic function parameters were acquired, including peak phase(PP), phase standard deviation (PSD), phase histogram bandwidth(PHB), histogram skewness(HS), histogram kurtosis(HK), and end-diastolic volume( EDV), end-systolic volume (ESV), left ventrieular ejection fraction (LVEF). All patients were divided into 4 groups: the normal group (147 cases), ischemic cardiomyopathy group (114 cases), nonischemic cardiomyopathy without left bundle branch block (LBBB) group(50 cases)and nonischemic cardiomyopathy with LBBB group(32 cases). The relationship between systolic synchrony parameters and systolic function parameters were analyzed with Pearson correlation analysis.Results:Statistic results for all patients showed that PSD and PHB were well correlated with LVEF( r values: -0.790, -0.799, both P<0.01), but PP was poorly correlated with LVEF( r=-0.194, P<0.01); HS, HK were positively correlated with LVEF( r values: 0.767, 0.676, both P<0.01); PSD, PHB were positively correlated with ESV( r values: 0.778, 0.795, both P<0.01) and EDV ( r values: 0.722, 0.732, both P<0.01); but PP was poorly correlated with ESV( r=0.145, P<0.01) and not correlated with EDV ( r=0.095, P>0.01). HS, HK were negatively correlated with EDV and ESV ( r values: -0.700 to -0.580, all P<0.01). PSD and PHB showed negatively correlation with LVEF ( r values: -0.834 to -0.492, all P<0.01), while HS, HK showed positive correlation with LVEF ( r values: 0.243-0.792, all P<0.01) in normal group, the ischemic cardiomyopathy group, the nonischemic cardiomyopathy without LBBB group and the nonischemic cardiomyopathy with LBBB group. Conclusions:The left ventricular systolic synchrony parameters provided by CZT SPECT GMPI correlate well with the left ventricular systolic function parameters, and the worse systolic function, the worse systolic synchrony. Both ischemic cardiomyopathy and non-ischemic cardiomyopathy can affect left ventricular mechanical contraction synchrony, and the effect on contraction synchrony in non-ischemic cardiomyopathy patients with LBBB is greater.

OBJECTIVE To evaluate the effectiveness， safety and economy of baloxavir marboxil in the treatment of influenza， and to provide evidence-based reference for the introduction of new drugs in hospitals and clinical medication decisions. METHODS Retrieved from PubMed， Embase， Web of Science， Cochrane Library， Epistemonikos， CBM， CNKI， VIP， Wanfang database， official websites and relevant databases of health technology assessment （HTA） institutions， the results of the included studies were descriptively analyzed after literature screening， data extraction and quality evaluation. RESULTS A total of 11 studies were included， involving 6 systematic reviews/meta-analyses and 5 pharmacoeconomic studies. Compared with placebo， baloxavir marboxil significantly shortened the time to alleviation of symptoms （TTAS） and time to resolution of fever （TTRF）， reduced the virus titer change from baseline at 24 h and 48 h after treatment and the incidence of bronchitis， with statistical significance （P＜ 0.05）. Compared with neuraminidase inhibitors （NAIs）， there were no significant differences in shortening TTRF and reducing the incidence of complications， pneumonia and bronchitis （P＞0.05）. The majority of studies suggested that there were no significant differences in shortening TTAS （P＞0.05）. Only very low-quality literature suggested that baloxavir marboxil could significantly reduce the virus titer change from baseline at 24 h and 48 h after treatment. In terms of safety， the incidences of adverse events （AEs） and drug-related adverse events （DRAEs） induced by baloxavir marboxil showed no significant differences， compared with peramivir and zanamivir （P＞0.05）. Some studies considered that the incidences of AEs and DRAEs with baloxavir marboxil were lower than placebo， oseltamivir and laninamivir. Compared with oseltamivir in China and laninamivir in Japan， baloxavir marboxil showed cost-effectiveness advantages. CONCLUSIONS Compared with placebo， baloxavir marboxil has good efficacy， safety and economy. Compared with NAIs （oseltamivir）， baloxavir marboxil has good economic advantages in China， but further high-quality studies are still needed regarding its safety and efficacy.
