Objective:To compare the clinical effects of bridge combined internal fixation system and locking plate system in treating closed humeral shaft fracture.Methods:From August 2017 to August 2020, there were 45 patients with closed humeral shaft fracture treated with surgery. Bridge combined internal fixation system were performed in 19 patients (bridge combined group, aged 38.3±11.9, range 21-72 years), including 13 males and 6 females. Further, there were 26 patients underwent locking plate system (locking plate group, aged 41.2±14.7, range 20-79 years), including 20 males and 6 females. The operation was performed by minimal invasive percutaneous osteosynthesis with fixators. The patients were followed up every 4 weeks. The fracture healing condition was recorded. Shoulder function was assessed according to University of California at Los Angeles (UCLA) shoulder rating scale and elbow function was assessed according to Mayo elbow performance score (MEPS).Results:The follow-up duration of all patients were 14.2±4.7 (range 10-32) months. All wound were healed completely. The operation duration in bridge combined group (68.1±12.5 min) was longer than that in locking plate group (56.3±11.6 min) ( t=3.32, P=0.002). The blood loss of bridge combined group and locking plate group were 112.6±20.2 ml and 104.2±14.1 ml, respectively ( t=1.65, P=0.107). The volume of drainage of bridge combined group was 68.4±16.2 ml and that of locking plate group was 73.1±14.9 ml ( t=1.00, P=0.323). The hospitalization time of bridge combined group was 9.7±2.3 d and the locking plate group was 9.4±1.9 d ( t=0.57, P=0.573). All above parameters had no statistical significance between the two groups. Fracture nonunion occurred in 1 of 19 patients in bridge combined group. The fracture healing time was 15.3±4.3 weeks in another 18 cases, while that of locking plate group was 15.9±3.9 weeks ( t=0.47, P=0.638). At 4-weeks postoperative follow-up, the UCLA shoulder score (18.1±3.9) and the MEPS (55.4±6.8) of bridge combined group were lower than those of locking plate group ( P<0.05). At 8-weeks postoperative follow-up, the shoulder score (26.2±4.3) and the MEPS (70.9±6.5) of bridge combined group were lower than those of locking plate group ( P<0.05). At 12-weeks postoperative follow-up, the UCLA shoulder score (33.6±1.0) and the MEPS (91.0±3.7) of bridge combined group had no statistical difference with those of locking plate group ( P>0.05). Conclusion:The bridge combined internal fixation system could provide personalized and multidimensional fixation according to the fracture type. The clinical effects of bridge combined internal fixation system on humeral shaft fracture are similar to the locking plate system at 12 weeks postoperatively. However, the operation duration of bridge combined system is longer and with increased the risk of nonunion.
ABSTRACT
Objective:To explore the effects of lateral closed wedge osteotomy plus locking plating via a small incision and posterior lateral approach on adult cubitus varus.Methods:A retrospective analysis was conducted of the 19 adults with cubitus varus who had been admitted to Department of Hand Surgery, Wuhan Fourth Hospital from July 2013 to September 2017.They were 3 males and 16 females, aged from 17 to 27 years (average, 20.3 years). The left side was affected in 13 cases and the right side in 6 ones. The angle of cubitus varus was 20.7°±2.8°. The lifting angle on the healthy side and the cubitus angle on the affected side were accurately measured on the Medical Image Archiving and Transmission System (PACS) to calculate the osteotomy angle. Lateral closed wedge osteotomy plus locking plating was conducted to correct the deformity via a small incision and posterior lateral approach. The lifting angle on the affected side was measured at the last follow-up. The Mayo elbow performance scores(MEPS) was used to evaluate the elbow function and the Bellemore scoring system the effects of elbow correction surgery.Results:The 19 patients were followed up for 9 to 32 months (mean, 14 months). A good healing was observed at the osteotomy site in all patients. At the last follow-up, the elbow lifting angle was 11.4°±1.6° and the surgical scars averaged 4 cm (from 3 to 5 cm). The cubitus varus was significantly improved after operation, leading to fine elbow function. According to the MEPS, 10 cases were excellent, 7 good and 2 moderate. According to the Bellemore scoring system, 13 cases were excellent and 6 good. After operation, injury to partial ulnar nerve was observed in 2 cases and one patient developed mild elbow stiffness. Follow-ups revealed no implant failure like loosening or breakage and none cases of delayed fracture union or non-union.Conclusions:The osteotomy angle should be accurately measured on the PACS before operation. Lateral closed wedge osteotomy plus locking plating should be performed via a small incision and posterior lateral approach. These procedures can ensure the orthopedic angle and postoperative recovery of the elbow joint, resulting in a limited surgical scar, beautiful appearance and fine efficacy.

ABSTRACT
Objective To investigate the role of β-catenin,the core protein of canonical Wnt/β-catenin signaling,in the inner-ear development and polarity regulation.Methods β-catenin was conditionally deleted from precursor cells of inner-ear sensory epithelium (Sox2-positive cells) in embryonic mice.Morphological changes of the inner ear were observed.Immunofluorescence staining was performed to basilar membranes,utricles and saccules to observe the hair-cell changes in arrangement and polarity.Results Compared with the control group,knock-out of β-catenin in Sox2-positive cells resulted in smaller otic vesicles,cochleas and vestibules,and fewer hair cells (HCs) in vestibular sensory epithelium (P<0.01).Stereocilium showed misorientation and kinocillia had a change in location and quantity in the cochlea.Scattered misorented HCs were also observed in the vestibule.Conclusions β-catenin is crucial for the development of inner ear and polarity manipulation of HCs in mice.The canonical Wnt/β-catenin signaling may be involved in the regulation of cochlea extension and planar cell polarity (PCP) of inner ear,which is known to be controlled by non-canonical Wnt/PCP signaling.

ABSTRACT
This paper aimed to investigate the anti-influenza virus activity of the genus Paeonia, screen potential anti-influenza virus compounds and predict targets of anti-influenza virus to explore the mechanism of anti-influenza virus activity. First of all, a total of 301 compounds of the genus Paeonia were summarized from the literatures in recent ten years. The candidate active ingredients from the genus Paeonia were identified by database such as PubChem and Chemical Book. The ligands were constructed by ChemDraw, Avogadro and Discovery Studio Visualizer. Secondly, 23 potential anti-influenza virus targets were developed by combining the target database and the literatures. Uniprot database was used to find the anti-influenza virus targets, and RCSB was used to identify targets associated with anti-influenza virus activity as docked receptor proteins. QuickVina 2.0 software was used for molecular docking. Finally, the Cytoscape 3.5.1 software was used to map the potential activity compounds of the genus Paeonia against influenza virus and the anti-influenza virus target network. Uniprot online database was used to analyze the target GO enrichment and KEGG metabolic pathways. The results showed that 74 compounds of the genus Paeonia had anti-influenza virus effect and 18 potential anti-influenza virus targets were screened. GO analysis concluded that the mechanism of the genus Paeonia anti-influenza virus is consistent with the mechanism of NA anti-influenza virus in order to stop the sprouting, dispersion and diffusion of virus and reduce the ability of virus to infect, so that the infection can be restricted so as to achieve the anti-influenza virus effect.
ABSTRACT
Pompe disease, also called type II glycogen storage disease, is a rare autosomal recessive inherited disease caused by the storage of glycogen in lysosome due to acid α-glucosidase (GAA) deficiency, with the most severe conditions in the skeletal muscle, the myocardium, and the smooth muscle. Patients may have the manifestations of dyspnea and dyskinesia, with or without hypertrophic cardiomyopathy. GAA gene mutation has ethnic and regional differences, and new mutation sites are found with the advances in research. Gene analysis is the gold standard for the diagnosis of Pompe disease. Conventional methods, such as skin and muscle biopsies and dried blood spot test, have certain limitations for the diagnosis of this disease. In recent years, prenatal diagnosis and newborn screening play an important role in early diagnosis of this disease. Enzyme replacement therapy (ERT) has a satisfactory effect in the treatment of this disease, but it may lead to immune intolerance. New targeted gene therapy and modified ERT will be put into practice in the future. This article reviews the research advances in the diagnosis and treatment of Pompe disease.

ABSTRACT
<p><b>OBJECTIVE</b>To observe the effect of Baichanting Compound (BC) on dopamine (DA) in striatum of Parkinson's disease (PD) mice, and to screen the optimal component proportion.</p><p><b>METHODS</b>The PD model was established in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) induced C57BL/6 mice. By using uniform design, they were intervened by three extracts of BC in different proportions [Acanthopanax senticosus extract (X1): white peony root extract (X2): Uncaria rhynchophylla extract (X3) = 30.00: 34.92: 82.50, 48.00: 19.98: 72.19, 18.00: 44.88: 61.88, 36.00: 29.94: 51.56, 54.00: 15.00: 41.25, 24.00: 39.90: 30.94, 42.00: 24.96: 20.63). Equal volume of 5% carboxymethylcellulose sodium was administered to mice in the model group and the normal group by gastrogavage. All medication was lasted for 20 successive days. The dopamine (DA) content was determined by ultra performance liquid chromatography tandem mass spectrometry (UPLC-MS). Except 10 in the normal group, 20 PD model mice were screened and divided into the model group and the BC group (with the optimal proportion) according to random digit table. BC extract in optimal proportion was administered to mice in the BC group by gastrogavage, while equal volume of 5% carboxymethylcellulose sodium was administered to mice in the model group and the normal group by gastrogavage. All medication was lasted for 20 successive days. Praxiology was observed in each group. DA content in striatum was also detected. Results Compared with the normal group, the DA content in striatum decreased significantly in the model group (P < 0.01), suggesting a successful PD modeling. Compared with the model group, the DA content in striatum increased significantly in 1 and 2 groups (P<0.05). According to results of quadratic polynomial stepwise regression statistics, the regression equation obtained was: Y = 0.265 + 0.026 X 2 - 0.056 X 3 + 0.334 x 10(-3) x X1 x X3 + 0.691 x 10(-3) X X3(2). X3 extract was the main factor influencing the effectiveness (P < 0.01). The optimal proportion of BC was predicted by the regression equation: X1 = 54.00 mg/(kg x d), X2 = 44.88 mg/(kg x d), the X3 = 82.50 mg/(kg x d). The pole climbing time was shortened, times of autonomic activities increased, DA content was elevated, all with statistical difference in BC groups (P < 0.01, P < 0.05).</p><p><b>CONCLUSION</b>BC could increase DA content in PD model mice with the optimal proportion as 54.00: 44.88: 82.50.</p>

Objective To determine the curative effect of stabilizing unstable pelvic ring fracture using the anterior subcutaneous internal fixator (INFIX).Methods From July 2013 to June 2014,15 cases who suffered from anterior pelvic ring fracture were treated with the device.There were 11 males and 4 females,with mean age of 38.5 years (range,23-65 years).Eight cases sustained fracture in traffic accidents,4 in high falls,and 3 in crush injury.According to the Young-Burgess and AO/OTA classification systems,type APC2 or 61-B1 was noted in one case,LC1 or 61-B2.1 in 4 cases,LC2 or 61-B2.2/61-B2.3 in 6 cases,and VS or 61-C1/61-C2 in 4 cases.Basic method in anterior ring fixation was one pedicle screw was respectively inserted into the area between the anterior superior iliac spine and anterior inferior iliac spine of both sides.The precontoured rod was then tunneled subcutaneously from one screw to the other.For the stable posterior injury in pelvic ring fracture,the anterior pelvic ring was stabilized only using the technique.For the unstable posterior injury in pelvic ring fracture,the anterior and posterior ring were both fixed using the technique.During follow-up visits,patients' tolerance to the device,wound infection,myositis ossificans,internal fixation lessening,and lateral femoral cutaneous nerve injury were evaluated.Results Follow-up ranged from 6-12 months (mean,7.5 months).The device was well tolerated by the patients for comfort.None had surgical site infection and internal fixation loosening.Injuries healed without loss of reduction at the 3-month follow-up.Injury of the lateral femoral cutaneous nerve at the both side was reported in 4 cases and at one side in 2 cases,but all restored 3 month after operation.Conclusion The reported technique is minimally invasive with few complications and reliable results,hinting an ideal method to stabilize the anterior pelvic ring fracture.
