Objective To compare the efficacy of TightRope loop plate and Endobutton plate in the treatment of acromioclavicular joint dislocation.Methods A retrospective analysis was conducted on 94 patients with acromioclavicular joint dislocation who were treated at this center from March 2021 to February 2023.They were divided into two groups based on different admission date.The Group E(n =47)received Endobutton plate treatment between March 2021 and February 2022,while the Group T(n =47)received TightRope loop plate treatment between March 2022 and February 2023.At the last follow-up,the perioperative indicators,Visual Analogue Scale(VAS),Constant-Murley shoulder joint function scores,and surgical complications were compared between the two groups.Results The surgical time,intraoperative bleeding,incision length,and VAS scores at 7 days after surgery in the Group T were shorter or lower than those in the Group E(P<0.05).There were no statistical differences in the incidence of perioperative nerve injury,internal fixation displacement,clavicle fracture,vascular injury,and infection between the two groups(P>0.05).The subjective and objective scores of Constant-Murley shoulder joint function in both groups at9 months after surgery showed significant improvement compared to preoperative scores(all P =0.000).There was no significant difference in the subjective and objective scores of Constant-Murley shoulder joint function between the two groups at 9 months after surgery(P>0.05).Conclusions The treatment of acromioclavicular joint dislocation with TightRope loop plate ot or Endobutton plate has a significant effect and can effectively improve shoulder joint function.Compared with Endobutton plate,use of TightRope loop plate has minor surgical trauma,less bleeding,and significantly reduced postoperative pain,being more conducive to early functional exercise for patients.

Objective: To explore the method and result of repairing segmental ear defect with postauricular skin flap according to different region. Methods: 25 partial ear defects were divided into 5 regions.The cases with defect in 1 and 2nd regions were treated by postauricular flap combined with ipsilateral conchal cartilage graft in one stage; Cases in the 3rd regions were repaired with the posterior pedicled flap combined with conchal or rib cartilage graft in two stages; According to the defect in 4th region, post-auricular skin flap was transplanted anteriorly to repair; The temporal fascial flap and skin graft were used for the 3 cases with post-operative cartilage exposure. Results: All flaps survived with good shape except one case with partial epidermal necrosis and 3 cases deep color after the temporal fascial flap and skin graft. 9 cases that needed second operation. Conclusions The postauricular flap is a preferred alternative method in case periauricular skin is in fact, which yields closer tissue match, color, and texture. It is safe and effective for the correction of segmental ear defect with satisfied shape. The temporal fascial flap can be regarded as the last alternatives.

BACKGROUNDOptimizing treatment outcomes for depression requires understanding of how evidence-based treatments are utilized in clinical practice. Antipsychotic medications concurrent with antidepressant treatment are frequently used in major depression, but few studies have investigated trends and patterns of their use over time. This study aimed to examine the prescription patterns of antipsychotic medications for major depression in China from 2002 to 2012 and their association with treatment satisfaction and quality of life (QOL).

METHODSA total of 3655 subjects with major depression treated in 45 Chinese psychiatric hospitals/centers nationwide were interviewed between 2002 and 2012. Patients' socio-demographic and clinical characteristics including psychopathology, medication side effects, satisfaction with treatment and QOL were recorded using a standardized protocol and data collection.

RESULTSThe frequency of antipsychotic use was 24.9% in the whole sample; the corresponding figures were 17.1%, 20.3%, and 32.8% in 2002, 2006, and 2012, respectively (χ2 = 90.3, df = 2, P < 0.001). Multiple logistic regression analyses revealed that patients on concurrent antipsychotics had significantly more delusions or hallucinations, longer illness duration, greater side effects, and more likely to be treated as inpatients and in major hospitals (i.e., Level-III hospital). Antipsychotic use was associated with lower treatment satisfaction while there was no significant difference with respect to physical and mental QOL between the antipsychotic and nonantipsychotic groups.

CONCLUSIONSConcurrent antipsychotic use was found in about one in four treated depressed patients in China, which has increased over a 10-year period. Considering the association of drug-induced side effects and the lack of patients' and relatives' satisfaction with antipsychotic treatment, further examination of the rationale and appropriateness of the use of antipsychotics in depression is needed.

OBJECTIVETo assess the clinical efficacy on adhesive ileus treated by electroacupuncture (EA) at Zhigou (TE 6) and Zusanli (ST 36), and to explore the different effects of acupoint and non-acupoint.

METHODSForty cases were randomized into an acupoint group and a non-acupoint group, 20 cases in each one. At the same time of the basic treatment, in the acupoint group, EA was applied at bilateral Zhigou (TE 6) and Zusanli (ST 36). In the non-acupoint group, EA was applied at the sites (that were neither on any meridian nor belonged to any acupoint) that were 0.5 to 1 cm lateral to Zhigou (TE 6) and Zusanli (ST 36) on both sides. Acupuncture was given twice a day, lasting for 4 days totally. The situation of abdominal pain, the time for the improvement in abdominal distention, the time of first voluntary defecation, the time of solid food intake and the others were observed.

RESULTSIn the acupoint group, the abdominal pain and distention were relieved rapidly as compared with those in the non-acupoint group. The results of the assessment face scale (AFS), the first anal exhaust time [(51.35 +/- 32.40) h vs (101.85 +/- 53.87) h], the first defecation time [(82.70 +/- 57.27) h vs (154.70 +/- 145.28) h] and the first solid food intake time [(119.65 +/- 56. 16) h vs (231.95 +/- 180.89) h] were all remarkably improved as compared with those in the non-acupoint group, presenting the statistical significance (P<0.05, P<0.01). Concerning the case number for the conversion to surgery, the death number and the number for the re-admission in 1 year follow-up visit, there was no significant difference in statistics between two groups (all P>0.05). But, the data suggested that the results were improved in tendency in the acupoint group.

CONCLUSIONEA at Zhigou (TE 6) and Zusanli (ST 36) achieves the good clinical efficacy on adhesive ileus. This therapy can remarkably improve abdominal pain and distention and promote the intestinal peristalsis for the patients and is superior to EA at non-acupoint.

OBJECTIVETo investigate the feasibility of construction of tissue-engineered skin in vitro.

METHODSFibroblasts were seeded on the dermal surface of acellular dermal matrix (ADM). 7 days later, epidermal cells (5 x 10(5)/cm2) were mixed with fibroblasts (0.2 x 10(5)/cm2) and then seeded on epidermal surface of ADM. The culture medium was the mixture liquor containing K-SFM in half and the culture supernatants of fibroblasts in half. In the control group, only epidermal cells (5 x 10(5)/cm2) were seeded and cultured with K-SFM. After composite skin was cultured for 1 week and 3 week, samples were harvested respectively for morphological study and to receive identification by immunohistochemistry.

RESULTSAfter 3-week culture, there were 3-4 continuous layers of cells in the epidermis in the experiment group. The epidermis was attached tightly to the dermis with trochanterellus. But in the control group, there were just 1-2 layers of cells in the epidermis which was not connected to the dermis. Strong positive dye of Laminin indicated that basement membrane was thoroughly formed in the experiment group. The same result was demonstrated by transmission electron microscope.

CONCLUSIONSThe mix-seeding of epidermal cells and few fibroblasts would promote the adhesion and proliferation of epidermal cells on ADM, and the formation of basement membrane.

OBJECTIVETo explore the influence of nonylphenol (NP) on the neural behavioral development of filial generation rats exposed via placenta.

METHODSOn the first day of the pregnancy, the SD rats were divided into four groups, and orally administered with NP at doses of 0, 50, 100 and 200 mg/kg on gestational day 9 approximately 15 respectively. The offspring rats of each groups were examined to observe the impact of NP on the early physiological, neurobehavioral development. The changes of filial generation body weight (from generation day 1 to 28) were measured. Brain tissues were stained with Hematoxylin-eosin and Congo red to observe with optical microscope.

RESULTSIn contrast to the control group, the early physiological markers (pinna detachment, hair growth, tooth growth and eye opening) and the early neurobehavioral development indices (surface righting, air righting, acoustic startle and visual placing) were significantly delayed in the groups of NP 200mg/kg dose (P < 0.05). The developing time of physiological markers decreased from (4.5 +/- 0.8, 5.2 +/- 0.8, 12.7 +/- 1.4, 16.0 +/- 1.7) d to (3.6 +/- 0.5, 3.6 +/- 0.5, 11.1 +/- 1.1, 12.7 +/- 1.3) d while neurobehavioral developing time decreased from (6.5 +/- 0.8, 11.3 +/- 0.5, 11.2 +/- 1.0, 20.2 +/- 1.0) d to (5.1 +/- 0.4, 8.3 +/- 0.5, 9.3 +/- 0.5, 9.3 +/- 0.5) d (P < 0.05 or P < 0.01). The body weights of filial generation rats were decreased obviously from 1 st day to 28th day. Histopathological examination displayed that hippocampal neurons had congestion and oedema in the group of 100, 200 mg/kg dose.

CONCLUSIONExposures to NP during gestation might impair the neurobehavioral development of F1 rats significantly.

Objective To analyze etiology of hospitalized hypertensive patients in the department of hypertension from 1999 to 2008. Methods This retrospective study was performed to analyze the etiology of hospitalized hypertensive patients in department of hypertension and to show the distribution change of hypertension from 1999 to 2008. Results ( 1 ) There were 5867 ( 75. 1% ) patients with essential hypertension and 1942 (24. 9% ) patients with secondary hypertension (SH). (2) The prevalence rate of SH increased significantly during the 10 years (χ2 = 387.621 ,P ＜ 0.001 ) and was higher in 2008 than in 1999 (39. 3% vs. 9. 5% , P ＜ 0. 05 ). The prevalence of obstructive sleep apnea syndrome (OSAS) and primary aldosteronism (PA) in 2008 increased 38.3 and 1.8 times respectively than in 1999 (χ2 =304. 025 ,P ＜0. 001; χ2 =42. 845 ,P ＜0. 001 ) and other SH remained unchanged. ( 3 ) The prevalence of PA complicated with OSAS increased significantly in recent five years ( χ2 = 26.376, P ＜0. 001 ). Incidence of OSAS was 23.9% in PA patients and incidence of PA was 6. 7% in OSAS patients. Conclusions With the insights gained on hypertension mechanism and the development of new diagnostic technology, percent of diagnosed SH increased remarkably in recent years in hospitalized hypertensive patients in our department of hypertension. OSAS and PA are the leading causes of SH.

Objective: The purpose of this study was to evaluate the safety and effectiveness of fast track surgery in laparoscopic gastrectomy for gastric cancer. Methods: All patients received elective gastric cancer resection, and were divided into three groups: group Ⅰ (open gastrecomy, n = 30) , group Ⅱ (open gastrecomy with fast track surgery, n = 30) , and group Ⅲ (laparoscopic gastrecomy with fast track surger-y ,n =30) . Clinical data and gut function were assessed in three groups. Results: There were no significant differences in postoperative complication and the number of lymph node harvest between 3 groups. Blood loss was less in group Ⅲ than group Ⅰ and group Ⅱ (P <0.01) ,but its operative time was longer and its cost was more than other two open surgery groups (P < 0. 01). Recovery of bowel function in group Ⅲ was faster,and postoperative hospital stay was shorter than group Ⅰ (P<0.01). However, recovery of bowel function and postoperative hospital stay in group Ⅲ was not different from group Ⅱ (P > 0. 05). Conclusion: Postoperative hospital stay can be shorter and recovery of bowel function can be faster in laparoscopic gastrectomy with fast track surgery plan compared to traditional care group. But when using fast track surgery plan, laparoscopic gastrectomy was not superior to open surgery.

BACKGROUNDDeltaDNMT3B (a new DNMT3B subfamily) expression is initiated through a novel promoter. We identified at least 7 transcription variants of deltaDNMT3B as a result of alternative pre-mRNA processing. The aim of this study was to detect the expression pattern of deltaDNMT3B variants in non-small cell lung cancer (NSCLC) and to explore the role of deltaDNMT3B variants in regulating the promoter-specific DNA methylation.

METHODSSpecific polymerase chain reaction (PCR) primer sets were designed to distinguish individual deltaDNMT3B variants according to their splicing patterns. The expressions of seven deltaDNMT3B variants were measured in 13 cell lines, 109 NSCLC patients, and the corresponding normal lung tissues using reverse transcription-PCR (RT-PCR). The status of the p16 and RASSF1A promoter methylations in the tumors was detected using a methylation specific PCR (MSP). The relationships of the expression patterns of the deltaDNMT3B variants were analyzed by observing the status of p16 and RASSF1A promoter methylations in the tumors. The siRNA and the anti-sense oligo-dioxynucleotide specifically targeting the junction of exon 5 and 7 of deltaDNMT3B were designed and transfected by lipofectmane 2000 into H1299 and H358 cell lines. RASSF1A promoter methylation from cells treated by siRNA-deltaDNMT3B4/2 was detected using MSP and Bisulfite sequencing, and Western blotting was used to detect the protein expression of DNMT3B and ADNMT3B. Cell growth and cell cycle distribution were measured by applying real-time cell growth analysis and flowcytometry, respectively.

RESULTSADNMT3B variants, not DNMT3B, were the predominant transcripts in both NSCLC cell lines and primary tumors. The expression of deltaDNMT3B4 strongly correlated to the promoter methylation status of RASSF1A in a primary NSCLC. The knockdown of deltaDNMT3B4/2 by RNA-interference or anti-sense approaches resulted in a complete demethylation of RASSF1A promoter with the reactivation of a RASSF1A gene expression in less than 12 hours, but no effect resulted from the p16(INK4a) promoter in the NSCLC cell lines.

CONCLUSIONSThese results demonstrate an important role of deltaDNMT3B4/2 in the maintenance of promoter-specific DNA methylation in a cell type specific manner and provide a novel cell model for the study of the regulation of replication-independent DNA methylation.
