1.Principles and progress in treatment of talus fracture
Chinese Journal of Orthopaedic Trauma 2021;23(4):329-336
Although talus fractures are not common among foot and ankle injuries, their treatment is difficult because of their complications and poor prognosis. They can be treated conservatively or surgically, with a variety of treatment protocols. At present, the main strategy of surgical treatment is to use strong and effective fixation to restore anatomic structure of the talus and preserve blood supply to the talus as much as possible so that deformity can be avoided and early healing be facilitated. This paper reviews the difficulties and current situation, and summarizes principles and the latest progress in clinical treatment of talus fractures, hoping to provide useful references for the treatment.

OBJECTIVETo compare two kinds of method for treating lumbar tuberculosis with psoas abscess, to provide reference for clinical reasonable select of therapy treatment.
METHODSFrom January 2010 to January 2013,42 patients with lumbar tuberculosis combined with psoas abscess with obvious surgical indications were enrolled, including 24 males and 18 females with an average age of (38.5 ± 10.2) years old ranging from 21 to 63 years old. All patients were followed up for 18 to 24 months with an average of 20.9 months. Twenty-two patients underwent posterior vertebral body lesions cleared, bone graft fusion and internal fixation and percutaneous puncture catheter drainage for treatment of psoas major abscess as group A, and twenty patients underwent one-stage extraperitoneal approach to remove abscess, posterior vertebral body lesions cleared, bone graft fusion and internal fixation as group B. The operative time, loss of blood, length of hospital stay, clinical cure rate and other clinical results for the two groups were analyzed and compared.
RESULTSThe loss of blood was (452.3 ± 137.6) ml in group A and (603.5 ± 99.6) ml in group B, there was significant statistical difference (P < 0.05). The time of operation was (193.6 ± 91.2) min in group A and (230.5 ± 56.6) min in group B, there was significant statistical difference (P < 0.05). The time of operation and the loss of blood in group A were obviously less than which in group B. In group A 20 cases were cured and 2 cases relapsed, 19 cases were cured and 1 case relapsed in group B, there was no significant statistical differences between two groups regarding cure rate with chi-square test (χ² = 0.000, P = 1.000). All patients in two groups obtained good clinical curative effect. There were no significant statistical difference between two groups regarding for length of hospital stay with t-test (P > 0.05).
CONCLUSIONLumbar spinal tuberculosis with psoas abscess is not absolute indications for anterior open operation. Compared with the combined anterior and posterior surgical procedure, the percutaneous puncture catheter drainage combined with posterior debridement, interbody fusion and internal fixation can achieve the same clinical effect but less trauma for the patients.

Objective To make a further understanding of mammographic features of simple cyst of the breast (SCB).Methods Molybdenum target radiographic signs in 39 cases with SCB proved pathologically and were retrospectively analyzed. Results Of the 56 SCB in 39 cases, 23 were diagnosed rightly as SCB, 10 as fibroadenoma, 2 as cancer and the remaining 4 were undefined. The diagnostic accuracy and misdiagnosis were 59.0% and 41.0% respectively. Radiograph showed round in 12, ovoid in 38, mild lobed in 4 and comet tail form in 2. The borders of cyst were distinct and sharp in 26, distinct partly and indistinct partly in 27,indistinct completely in 3. The density was homogeneous in 54 with calcifications in 2. Of the 56 SCB, the length axes of cyst were upright to chest wall in 20 and towards nipple in 18. The cysts could be transformed with pressure in 4.Conclusion Careful analysis of radiographic features of SCB is helpful for diagnosing accurately this disease.

Hedgehog signaling pathway is a conserved and important signaling pathway involved in proliferation and differentiation of many types of cells. Latest studies have found that Hedgehog signaling pathway may induce MSCs osteoblast differentiation by increasing the expression of the Runx2 and Osx and inhibit MSCs differentiate to adipocyte. Hedgehog signaling pathway may also promote osteoblast proliferation by regulating cyclin. This review summarizes the mechanism that Hedgehog signaling pathway regulates osteoblast differentiation and proliferation,and concludes that Hedgehog signaling pathway can regulate bone metabolism. It might provide new ideas for the treatment of osteoporosis.

Objective To review the safety and efficacy of upper-pole access percutaneous nephrolithotomy (PCNL). Methods From May 2008 to May 2010,237 cases ( 135 males and 102 females with mean age of 42 yrs) of renal or proximal ureteral calculi treated with upper-pole access PCNL were reviewed.The indications included calculus larger than 1.5 cm or impacted proximal ureteral calculi in 94 cases,calculus≥2 cm or impacted renal pelvic calculi in 26 cases,staghorn or multiple calculi in 68 cases,complex lower calyx calculi in 13 cases,upper calyx calculi not amenable to ESWL or URS in 12 cases,calculi within upper calyx diverticulum in 3 cases,combined UPJ obstruction or upper ureteral stenosis in 8 cases,morbidly obese patients in 3 cases,calculi within horseshoe kidneys in 6 cases,calculi within transplanted kidneys or ureters in 4 cases.Of the 237 cases,175 tracts (73.8%) were above the 12th rib,46were above the 11th rib,12 were below the 12th rib,4 were in the lower abdomen for renal transplant patients. Results The overall stone clearance rate with upper-pole access PCNL monotherapy was 74.3%.Additional punctures were required in 55 cases and combined ESWL in 6 cases.Total stone clearance rate at 3 months after operation was 88.2%.16 patients (6.8%) had a pleural injury.Thoracentesis was required in 8 patients,closed thoracic drainage in 5 patients,conservative treatment in 3 patients.After nephrostomy tube removed,pleural irritation symptom appeared in 12 cases (5.1%) who required symptomatic treatment.No patient had injury to the lung or other viscera.Significant bleeding requiring blood transfusion was olserved in 5 patients,while selective renal arterial embolization was required in 2 cases. Conclusions Upper-pole access offers optimal visibility,convenience for the movement of rigid nephroscope and high stone-free rate.It should be attempted in selected cages of upper ureteral calculi and complex renal calculi.

AIM To determine whether O-β -D-fructofuranosyl-〔(2→1 )-O-β-D-fructofuransyl〕4α-D-glucopyranoside (inulin-type hexasaccharide, IHS), a monomer extracted from the roots of Morinda of ficinalis How, has antidepressant action. METHODS Fo rced swimming tests in mice and rats and differential-reinforcement-of-low-r ate 72 second schedule (DRL 72 s) in rats were used. RESULTS In the forced swimming test in mice, IHS (80 mg*kg-1, po), like the effe ct of clinically effective antidepressant desipramine (10 mg*kg-1, ip), produced significant decrease in immobility time. IHS (20 mg*kg-1,po ) also elicited significant decrease in immobility time in forced swimming test in rats, which was comparable to the effect of desipramine (40 mg*kg-1, po). Moreover, in the DRL 72 s in rats, IHS (5~10 mg*kg-1, ip), s imilar to desipramine (5 mg*kg-1, ip), elicited significant increase in reinforcers. CONCLUSION These findings demonstrate that IHS has antidepressant action and is an effective component extracted from the root s of Morinda officinalis How.
