Objective The purpose was focused on discussing the causes of sciatic nerve injury following total hip replacement in order to introduce the methods for protecting sciatic nerve during operation by reviewing 655 consecutive total hip replacement and total hip revision. Methods From January 1998 to December 2001, 655 total hip replacement and total hip revision cases were performed in our hospital, 9 cases of which occurred as sciatic nerve injury postoperatively. There were 8 cases in 587 primary total hip replacements and one case in 68 total hip revisions. The 9 patients included 3 males with 3 hips and 6 females with 6 hips with an average age of 51 years ranging from 35 to 67 years old. In the group, 4 cases were diagnosed as avascular necrosis of femoral head, 2 cases as congenital acetabular dysplasia accompanied with osteoarthritis, 1 case as ankylosing spondylitis, 1 case as rheumatoid arthritis and 1 case as loosening of prosthesis. 8 prosthetic components of the hip were fixed by uncement, and the other one was fixed by cement. Results All of the 9 patients experienced sciatic nerve palsy sooner after operation, 8 cases of which suggested simple injury of common peroneal nerve, and 1 case a combined injury of common peroneal nerve and tibial nerve. Of the 9 cases, 7 cases underwent leg lengthening or soft tissue release because of hip joint stiffness during operation. After six to forty-eight months follow-up, the function of sciatic nerve was recovered completely in eight cases after half a year. The other one received total hip revision was not recovered from sciatic never palsy in six months, and the operation of never incision and exploration was performed. During operation, part of the sciatic nerve was found to become thinner without marked compression and other injury. Then release soft tissue around the injured never, the function of sciatic nerve was partly recovered one year after operation. Conclusion It is concluded that sciatic nerve injury associated with total hip arthroplasty is most commonly caused by over-lengthening the low extremity and mechanical compression. The function of sciatic nerve may be recovered in most patients with incomplete injury.

Objective To investigate the predictive value of the non-invasive indicator deceleration capacity of heart rate (DC) in the sudden cardiac death (SCD) after acute myocardial infarction. Methods A total of 417 myocardial infarc?tion patients with ST-segment elevation in sinus rhythm were enrolled in this study. DC was assessed from data of 24-hour ECG Holter. Regular follow-ups were carried out within 12 months. The SCD events were recorded and compared with pa?tients without SCD. Results During 12 months of follow-up, 20 patients were died due to SCD (4.8%). Compared with sur?vival group, patients showed significantly lower left ventricular ejection fraction (LVEF, 0.393 ± 0.065 vs 0.528 ± 0.042, P<0.05) and DC [(2.85±1.66) ms vs (5.49±1.71) ms,P<0.05]in SCD group. Multivariate Cox proportional hazard regression analysis showed that lower LVEF(<0.35)[RR: 2.167(1.384-4.661), P=0.013]and DC (DC<4.5 ms)[RR: 3.706(2.709-5.374),P=0.020]were risk factors for the occurrence of SCD. The prediction sensitivity by the decreased LVEF and DC was 52.1%and 76.4%respectively, and the specificity was 84.5%and 86.1%respectively. Conclusion The decreased value of DC after acute myocardial infarction can predict the SCD events.

[ABSTRACT]OBJECTIVETo explore the method on reconstruction of long and special tracheal defects which can mostly match with natural airway: pedicle rib cartilage with cilia endothelial wall.METHODS8 experimental model of rabbits were trained with cervical double belt blood supply fascia embedding and autologous costal cartilage and nasal septum mucos in the first period, then followed by transplantation in the second period. After the operation, we would assess the physiology, breathing and histopathology index of the rabbits, etc. After the animal experiment, we tried to apply the method to an appropriate clinical case.RESULTS8 cases of experimental rabbits dead after the second period operation with the average survival time of 21.9 days and caused by asphyxia. Histopathological results: rib cartilage and trachea ring up of cartilage cells and fibers have high similarity in histology; cartilage of all cases under the cultivation of the pedicle fascial package has not been absorbed; all cases' nasal septum mucosa in the body and blood supply to differentiation under fascia nutrition. Then we applied the method on a clinical case.CONCLUSIONTrachea ring rib cartilage had a higher similarity to the tracheal cartilage on the histology and biological characteristics that can be used as the preparation of artificial trachea shaping material or cell culture to tissue engineering materials. Package of rib cartilage pedicle fascial can provide adequate blood supply to make up for a free training rib cartilage defect to its absorption. Nasal septum mucosa of pressure in the body and blood supply of the fascia nutrition can simulate the trachea ciliated epithelium, which can play its biological characteristics similar to the inner wall of the trachea.

Objective:Influence of clinicopathological characteristics and different therapy patterns on the overall survival of patients with gastric cancer with bone metastasis was investigated. Methods:A total of 146 gastric cancer patients with bone metastasis were enrolled from December 1996 to December 2014. Data of clinicopathological characteristics, treatment methods, and overall survival were collected. Univariate and multivariate analyses were performed using log-rank tests and Cox's proportional hazard model, respec-tively. Results:A total of 51 (34.9%) patients had synchronous metastasis, while 95 (65.1%) had metachronous metastasis. Moreover, 35 (24.0%) patients only had bone metastasis, while 111 (76.0%) patients were complicated with other organ metastases, such as liver (30.0%), peritoneal (24.0%), lung (15.1%), and bone marrow (7.5%). After diagnosis of bone metastasis, bisphosphonates, bone radio-therapy and bone surgery were applied in 99 (67.8%), 34 (23.3%), and 5 (3.4%) patients, respectively. Additionally, 96 (65.6%) patients received palliative chemotherapy. The median overall survival was 5.8 months (95%CI:4.284-7.316). Multivariate analysis revealed that KPS<80 (P=0.030), bone marrow metastasis (P<0.001), elevated serum CA199 (P<0.001), and without palliative chemotherapy (P<0.001) were independent poor prognostic factors. Conclusion:The outcome of gastric cancer with bone metastasis is very poor, espe-cially in patients with bone marrow metastasis, worse KPS, and elevated CA199. Palliative chemotherapy may be beneficial for the sur-vival of these patients.

Objective: To observe the automatic ventricular capture management (VCM) conifrmed by paced depolarization integral (PDI) evoked response detection via the follow-up study in patients with Zephyr5826 pacemaker implantation. Methods: A total of 102 relevant patients were enrolled. In order to conduct PDI calculation, pacemakers were set by bipolar sensing and bipolar pacing at immediately after implantation. VCM functions were observed at 1 day, 7 days and 1 month, 3, 6, 12 months after implantation, the ventricular threshold by VCM test and manual test were compared. The symptoms of pectoralis major stimulus, diaphragm stimulus and palpitation were observed in all follow-up patients. Results: There was 1 patient died by MI at 1 month after Zephyr5826 pacemaker implantation, the rest 101 patients were followed-up for 12 months. VCM function was successfully turned-on at immediately after implantation in all patients, no pectoralis major stimulus and diaphragm stimulus occurred. VCM function was turned-off in 6/101 (5.9%) patients at 7 days after implantation due to intolerable palpitation caused by daily automatic VCM, instead they received manual test at follow-up visit. The coincidence rate of ventricular thresholds between VCM test and manual test were 100%. Ventricular pacing output voltage by VCM was (0.99 ± 0.48) V,n=608. Compared with regular pacing output voltage (2.5V, 0.4ms), VCM function may save 84% of energy consumption; compared to high pacing output voltage (3.5V, 0.4ms), VCM may save 92%. Loss of ventricular capture and poor sensation were not found by ECG and 24 h dynamic monitoring. Conclusion: Zephyr5826 pacemaker may conduct bipolar pacing and scanning with VCM function, it can be effectively and safely operated by low energy output. A few patients may not use VCM function due to intolerable palpitation.

Objective To compare the difference and consistency between OPD-Scan Ⅲ and IOL-Master 700 in the measurement of corneal curvature(flat keratometry,K1 and steep keratometry,K2)and horizontal corneal diameter(white-to-white(WTW)distance).Methods Totally 268 patients with 328 eyes(164 right eyes and 164 left eyes)who underwent cataract surgery at the Department of Ophthalmology of the Aerospace Centre Hospital from October 2021 to September 2022 were selected for this study.The K1,K2,and WTW values of the sampled right or left eyes were measured and analyzed using OPD-Scan Ⅲ and IOL-Master 700,respectively.Parameter comparisons were performed through paired t-tests;correlations between parameters were detected through the Pearson correlation analysis;and the Bland-Altman method and intragroup correlation coefficient(ICC)analysis were employed to determine the consistency of parameter measurements between the two instruments.Results The K1 and K2 values measured by OPD-Scan Ⅲ were greater than those measured by IOL-Master 700,while the WTW values were lower than those measured by IOL-Master 700,but the differences were statistically significant(all P＜0.001).K1,K2,and WTW values measured by OPD-Scan Ⅲ were positive-ly correlated with the corresponding values measured by IOL-Master 700,and the differences were statistically significant(all P＜0.001).The proportions of K1,K2,and WTW values outside the 95％limits of agreement for both instruments were within 5％,but the absolute value of the difference in values within the 95％limits of agreement was close to or more than(1.0)D,indicating a sizeable clinical deviation.ICC analysis confirmed a good consistency between K1 and K2 values of the left and right eyes measured by the two instruments(ICC＞0.90).The difference in WTW values measured by the two instruments was significantly correlated with K2 values(both P＜0.05).There were 5 samples(83.33％)outside the positive deviation range of WTW values,of which K2 measured by IOL-Master 700 was above 47.03.Conclusion The OPD-Scan Ⅲ and IOL-Master 700 have been found to have measurement biases when assessing K1,K2 and WTW.In clini-cal practice,the two instruments cannot be interchanged as an alternative to each other.The WTW values measured by IOL-Master 700 are greater than those obtained by OPD-Scan Ⅲ;when K2≥47.03,the WTW values may not be reliably ref-errable.

The fourth time national survey of Chinese materia medica (CMM) was used. The quadrat survey contained recording on species and amounts of plants, collection of specimens and CMM. The weight of main medicinal plant was measured. The quadrat numbers were calculated on regions, plant species and sea level of samples from different regions. There were 703 species of medicinal plants. The 143 species of main medicinal plants, which occupied to 74.5% in main medicinal plants in Chongqing, belonged to 71 families and 132 genera. There were 128 species of wild main medicinal plants. The 30 species of main medicinal plants were cultivated (including 15 species of both wild and cultivated medicinal plants). Among them, 14 species were in large-scale cultivation. This investigation helped the understanding of present situation of medicinal species distribution in Chengkou County, the habitats of wild medicinal plants, and the resources reserves, which provided references for the continuous development of Chinese herbal medicine resources.
