OBJECTIVE: To study and compare the effect of indwelling drainage tube and extubation time on occult hemorrhage and functional recovery after total hip arthroplasty(THA). METHODS: From July 2017 to June 2018, 123 patients who underwent THA in our hospital for the first time were selected as the subjects of study. According to whether the drainage tube was retained or not and the time of extubation, they were divided into three groups:in group A, 41 patients (24 males, 17 females, age 53 to 77 years) did not put drainage tube after THA;in group B, 41 patients were removed 24 hours after THA, 26 males and 15 females, aged 55 to 74 years;in group C, 41 patients were removed 48 hours after THA, 25 males and 16 females, aged 52 to 75 years. The VAS score of pain 72 hours after THA, the total and recessive blood loss, the time of starting functional exercise, and the incidence of postoperative limb swelling were recorded. All the patients were followed up for one year after discharge. Harris hip score was used to evaluate the degree of hip function recovery one year after operation. RESULTS: The occult blood loss of group A, B and C were(513.6±25.3), (521.7±33.4), (519.3±29.8) ml, respectively, with no significant difference(>0.05). There was no significant difference in blood loss in operation among the three groups(>0.05). In group B and C, the postoperative apparent blood loss was more than that in group A (<0.05). There was no significant difference in VAS scores of the three groups before and 72 hours after operation (>0.05). The time of getting out of bed in group A was shorter than that in group B and C (<0.05), and that in group B was shorter than that in group C(<0.05). The Harris hip score at 1 year after operationof the three groups was significantly higher than that of before operation (<0.05). There was no significant difference in Harris hip score before and after operation among three groups (>0.05). There was no significant difference in the incidence of complications among three groups (>0.05). CONCLUSION Whether the drainage tube is left or not and the time of extubation have no significant effect on the latent blood loss and functional recovery after THA, but without drainage tube after THA can reduce the apparent blood loss, patients can get out of bed at 6 hours after THA, which is more conducive to the recovery and nursing of patients.

OBJECTIVETo compare clinical results of treatment of Pipkin type I and II femoral head fractures through modified Smith-Peterson(S-P) approach and modified Hardinge approach.

METHODSFrom July 2005 to July 2014, 42 patients with Pipkin type I and II femoral head fractures were treated with operation. A total of 23 patients in anterior group was treated with modified S-P approach including 17 males and 6 females with an average age of (29.3±9.4) years old, 5 cases of type I by excision of the fragement, 3 cases of type I and 15 cases of type II cases by fixation of the fragement. While a total of 19 patients in the lateral group was treated with modified Hardinge approach including 15 males and 4 females with an average age of (31.4±10.0) years old, 3 cases of type I by excision of the fragement, 4 cases of type I and 12 cases of type II by fixation of the fragement. Operative time, blood loss during operation and fracture healing time were observed and compared. The clinical and radiographic outcomes of the patients were measured using Thompson-Epstein scoring scale. The effect of hip reduction time of less than 6 h, 6 to12 h, and more than 12 h, the effect of surgery time within 24 h and more than 24 h after injury were compared.

RESULTSAll patients were followed up from 24 to 60 months with an average of(30.29±6.95) months. The operation time (61.96±12.22) min, blood loss (46.09±18.03) ml, and (74.74±10.06) min, blood loss (72.11±19.88) ml in lateral group in the anterior group were better than those of lateral group(<0.05). In anterior group, fracture healing time was(12.22±1.70) weeks, the results were excellent in 8 cases, good in 10 cases, fair in 4 cases and poor in 1 case, the excellent and good rate was 78.3%, the incidence of avascular necrosis of femoral head was 8.69%(2/23), and the incidence of heterotopic ossification was 13.04%(3/23). While in lateral group, the fracture healing time was(12.42±1.95) weeks, the results were excellent in 6 cases, good in 7 cases, fair in 3 cases and poor in 3 cases, the excellent and good rate was 68.4%, the incidence of avascular necrosis of femoral head was 10.53%(2/19), and the incidence of heterotopic ossification was 5.26%(1/19). There was no significant difference in fracture healing time, postoperative effect and postoperative complications between the anterior group and lateral group(<0.05). The effect of patients with reduction time of hip dislocation less than 12 h was significantly better than that of more than 12 h, there was no significant difference in the effect between reduction time within 6 h and 6 to 12 h. There was no significant difference in the outcome between surgical patients within 24 h and more than 24 h after injury.

CONCLUSIONSDislocated hip of Pipkin type I and II femoral head fractures should be closed reduction within 6 h. If conditions are limited, the reduction time can be accepted within 12 h. Both of modified S-P approach and modified Hardinge approach are effective in treating Pipkin type I and II femoral head fractures, and can obtain excellent outcomes. Moreover, modified S-P approach has advantage of less trauma, less blood loss, shorter operative time.

OBJECTIVETo introduce percutaneous hollow screws for treatment of the vertical sacrum longitudinal fracture and evaluate the preliminary therapeutic outcomes.

METHODSFrom January 1999 to December 2006, 24 cases with vertical sacrum longitudinal fractures inchuded 15 males and 9 females were treated by percutaneous hollow screws, with an average age of 35 years ranging from 18 to 61 years. Accordng to Denis'classification of sacral fracture, there were 6 cases of type I, 11 of type 1 and 7 of type II.

RESULTSThe operation lasted for 30 to 65 minutes (averaged 48 minutes). All of them were followed up for 3 to 36 months (averaged 18.6 months). According to improved effective standard of pelvic trauma, the result of radiography was excellent in 18 cases, good in 5 and poor in 1, and the clinical evaluation was exellent in 16, good in 8.

CONCLUSIONTreatment of the vertical sacrum longitudinal fracture with percutaneous hollow screws is a comparatively reliable method and has the advantages of more precise with few postoperative complications and allows the patient early mobilization.

Objective : To investigate the influence and molecular mechanism of hypoxia-inducing factor-1 α( HIF- 1 α) gene silencing combined with methyl selenenic acid (MSA) on cervical cancer cell proliferation，apoptosis and cell migration． Methods : HeLa cells were transfected with HIF-1 interference RNA and negative control RNA．Af- ter transfection for 48 h，cells were stimulated with MSA for 24 h，and cell proliferation was determined by CCK-8 assay and colony formation．Apoptosis was determined by flow cytometry combined with Annexin V-FITC / PI．The expression levels of HIF-1α , Bcl-2 ，and E-cadherin were detected by Western blot assay． Cell migration ability was determined by Transwell assay. RNA-seq analysis was used to investigate the differentially expressed genes and differential signaling pathways. Results : Compared with the control group，interfering with HIF-1α combined with MSA significantly inhibited cell proliferation (P ＜0．01) ．Flow cytometry results showed that the combined drug group significantly induced apoptosis．Transwell results showed that interfering with HIF-1α combined with MSA inhibited HeLa cell migration．Compared with the control group，interfering with HIF-1α combined with MSA down- regulated the expression of Bcl-2 and up-regulated the expression of E-cadherin. RNA-sequencing combined with signal pathway enrichment results showed that the expression of apoptotic signal pathway and downstream genes was inhibited． Conclusion HIF-1α gene silencing combined with MSA can synergically inhibit the proliferation and induce apoptosis of cervical cancer cells，and its regulatory mechanism may be related to the expression of Bcl-2 family proteins and the inhibition of p53 signaling pathway.

OBJECTIVETo investigate the relationship of upper cervical pedicle and vertebral artery (VA) location in order to improve the safety of transpedicular screw insertion.

METHODSThe vertebral arteries on 12 sides of 6 adult pate cadaverous specimens were dissected. The distance between VA and VA groove at the atlas needling point of transpedicle screw, and the distance between VA and the inner edge of axis cervical foramen, and the VA external diameter in axis cervical foramen were measured respectively.

RESULTSThe distance between VA and VA groove was (1.96 ± 0.72) mm on the left and (1.99 ± 0.61)mm on the right at the atlas needling point of transpedicle screw, the distance between VA and the inner edge of axis cervical foramen was (2.23 ± 0.43) mm on the left and (2.30 ± 0.39) mm on the right, the VA external diameter in axis cervical foramen was (3.03 ± 0.48) mm on the left and (2.98 ± 0.75) mm on the right.

CONCLUSIONIt is unlikely to injury VA when the transpedicle screws of upper cervical vertebrae were implanted correctly besides high straddled VA, and the individualization must be performed in the process.

Mitochondrial dysfunction is closely related to the occurrence and development of benign and malignant diseases of the pancreas. Mitochondrial membrane of the respiratory chain electron transfer and energy transfer plays an important role in maintaining normal cellular function. When the respiratory chain was disrupted, the oxidative stress was increased in the cell, and produced a large number of oxide intermediate products which target mitochondrial protein, DNA, etc, lead to mitochondrial dysfunction finally induced acute pancreatitis, pancreatic cancer and other diseases. In addition, mitochondrial homeostasis plays an indispensable role in maintaining the normal function of islet cells. This paper reviewed the research status of mitochondrial dysfunction in pancreatic diseases.
