Rectal cancer has become the second most common gastrointestinal tumor in our country. With the development of comprehensive treatment, the long-term survival rate of patients with rectal cancer has greatly increased, meanwhile, higher postoperative quality of life is required. But the genitourinary dysfunction which is mainly caused by intraoperative pelvic autonomic nerve damage haunts postoperative rectal cancer patients. Traditional pelvic autonomic nerve protection technology born in the 1980s only improves urogenital function in a part of postoperative patients. In recent years, NOME(nerve-oriented mesorectal excision) was proposed, which needed to make pelvic autonomic never exposed. However, recovery of urinary function is not ideal due to difficulty identifying pelvic autonomic nerve and unavoidable damage on pelvic autonomic nerve. In clinical practice, we found that pelvic autonomic nerve can be divided into three parts: abdominal cavity, large pelvis, small pelvis. The pelvic autonomic nerve is closely related to the surrounding fascias in each part. The fascias are not only the protection of pelvic autonomic nerve, but also can be used as a good indicator of location of pelvic autonomic nerve. The relationship of pelvic autonomic nerve with Toldt fascia, presacral fascia, the lateral rectal ligaments, and the Denonvilliers fascia is discussed in this paper. Combined with the above theory, a new technology named FOPANP (fascia-orientation of pelvic autonomic nerve preservation) is proposed. In this technique, the fascia around the rectum is used as a guidance to select the appropriate plane in the operation, and the tumor can be removed without exposing the pelvic autonomic nerve. This technology has three advantages. First, it is not necessary to search and expose the pelvic autonomic nerve, so as to avoid secondary injury to it during the operation. Secondly, the pelvic fascias are natural barriers formed between the surgical plane and the pelvic autonomic nerve retained. They can avoid the stimulation of physical and chemical factors to pelvic autonomic nerve. Thirdly, because the fascias are easier to identify, and the texture is more tough, so the technology is easier to master.

OBJECTIVETo elucidate the course of pelvic autonomic nerves and its relationship with pelvic fascia in order to identify the safe plane to reduce the damage of pelvic autonomic nerves in total mesorectum I excision(TME).
METHODSThe course and distribution of pelvic autonomic nerves were observed and their relationship with pelvic interfascial space was examined through the anatomy of 12 adult pelvic specimens.
RESULTSThe entire course of hypogastric nerves ran within the anterior sacral fascia and the inferior hypogastric plexus ran within parietal fascia. Inferior hypogastric plexus crossed the fusion line of Denonvilliers fascia and parietal fascia in the 10 o'clock and 2 o'clock directions of the rectum, and joined urogenital vessel bundle finally. Laterigrade traffic nerves could be found in Denonvilliers fascia.
CONCLUSIONThe safe plane should be chosen between rectal proper fascia and anterior sacral fascia near rectal proper fascia in posterior dissection and lateral dissection of rectum. More attention should be paid to protect the neurovascular bundle in the 10 o'clock and 2 o'clock directions of rectum and traffic nerve within Denonvilliers fascia in anterior dissection.

OBJECTIVE:
To determine the effect of Tongxinluo on the endothelial function and hypersensitive C-reactive protein (hs-CRP) in acute coronary syndrome patients undergoing percutaneous coronary intervention(PCI).
METHODS:
Thirty-three patients with unstable angina pectoris and 6 patients with acute myocardial infarction who underwent PCI for stenotic lesions of the coronary artery were enrolled. The patients were randomly assigned to a conventional group (n = 19) which took routine treatment or a tongxinluo group (n = 20) which took Tongxinluo(4 capsules once, 3 times per day) at the base of routine treatment after PCI. Nitric oxide synthase (NOS), nitric oxide (NO), endothelium-dependent vasodilation which was evaluated in the brachial artery flow mediated diameter(FMD) and hs-CRP were measured before the PCI and 24 hours and 3 months after the PCI. The correlation between NO and hs-CRP was analyzed.
RESULTS:
NOS, NO, and FMD in the 2 groups 24 hours after the PCI were significantly lower than those before the PCI(P < 0.05), but hs- CRP obviously increased (P < 0.05). NOS, NO, and FMD 3 months after the PCI in the 2 groups were significantly higher than those before the PCI (P < 0.05 or P < 0.01), but hs-CRP obviously decreased (P < 0.01).All indexes mentioned above in the Tongxinluo group showed greater changes than those of the conventional group(P < 0.05). NO was negatively correlated with hs-CRP (r = -0.3219, P<0.01).
CONCLUSION
Tongxinluo capsules have obvious beneficial effect on endothelial function and anti-inflammation in acute coronary syndrome patients undergoing PCI, by directly acting on the endothelium and indirectly inhibiting inflammation.

Ubiquitination is one of the most important post-translational modification processes in eukaryotic cells,in which the ubiquitin molecules and/or ubiquitin chains are covalently transferred to the substrate after a series of enzymatic cascade reactions involving the activating (E1),conjugating (E2) and ligating (E3) enzymes.Coupling to the 26S proteasome complex to form the Ubiquitin-Proteasome System (UPS),ubiquitination plays an essential role in controlling protein stability,thereby maintaining the dynamic balance of the key cellular proteins.Besides,ubiquitination is also involved in a wide range of protein degradation-independent events,such as gene transcription and translation,signal transduction,DNA repair and endocytoais,exerting a key function in response to exogenous stimuli and the cellular homeostasis.Similar to kinases,components of the ubiquitination system are often dysregulated,leading to a variety of diseases,such as cancer.Recently,accumulating evidence has shown an increasing number of dysregulated ubiquitination processes in osteosarcoma (OS).Herein,this review briefly provides current perspectives on the aberrance of ubiquitination-associated factors and their roles in OS,providing novel insight into potential therapeutic targets of OS.

Objective:To compare the clinical effects robot navigation assisted and conventional proximal femoral nail antirotation (PFNA) implantation and fixation in the treatment of elderly femoral trochanteric fractures.Methods:A total of 86 elderly patients with tuberosity fracture of the femur were admitted as research samples from January to March in 2022 in the Department of Trauma Orthopaedic, Xi′an Honghui Hospital Affiliated to Xi′an Jiaotong University, including 37 males and 49 females, who aged from 63 to 92 years, with an average age of (79.6 ± 6.9) years. All patients were treated with intramedullary nails (PFNA), 32 with dimensity robotic-assisted therapy (robot group) and 54 with traditional methods (conventional group). The length of incision, the number of intraoperative fluoroscopy, the amount of intraoperative blood loss, and the operation time were recorded. The occurrence of postoperative complications in the two groups was observed. The rate of excellent hip Harris score at 3 month after surgery was compared between the two groups. Measurement data with normal distribution were represented as mean ± standard deviation( ± s), and the comparison between groups was conducted using the t-test; the comparison of count data were represented as [ n(%)], and was conducted by Chi-square test or Fisher exact probability between groups. Results:All patients were followed up for 9 to 12 months, with an average of (10.6 ± 0.9) months. The incision length and tip apex distance (TAD) of the robot group were (3.40±0.82) cm and (21.85±1.44) mm, which were smaller than (4.82±0.75) cm and (26.83±1.75) mm in the conventional group ( P<0.05 for all). The number of intraoperative fluoroscopy and guide needle adjustment [(14.53±3.26) and 0 times] in the robot group were less than those in the conventional group [(20.67±4.84) and (2.83±1.42)] ( P<0.05). The intraoperative blood loss and drainage rate of the robot group were (87.03±9.41) and (46.40±8.91) mL, which were smaller than that of the conventional group [(110.00±12.52) and (69.62±10.22) mL] ( P<0.05). There was no significant difference in the number of days of hospitalization and operation time between the two groups ( P>0.05). The postoperative complication rate in the robot group was 9.4%, which was lower than that in conventional group (42.6%), and the difference was statistically significant ( χ2=11.88, P=0.036). The excellent rate of postoperative hip joint function in the robot group was 75.0%, and the conventional group was 66.7%, and there was no significant difference between the two groups ( χ2=0.66, P=0.416). Conclusion:Robot-assisted navigation downward PFNA surgery can have good clinical effect in the treatment of femoral tuberosity fracture in the elderly, which can reduce the number of surgical incisions and intraoperative fluoroscopy, and reduce the incidence of postoperative complications, which is helpful to achieve minimally invasive surgery and rapid recovery of elderly patients with femoral tuberosity fracture.

Objective:To analyze the influence of vitamin D 3 supplementation on the clinical efficacy of mesalazine in patients with ulcerative colitis (UC). Methods:From January 2015 to December 2020, patients with mild-to-moderate active UC were retrospectively and continuously enrolled, who accepted mesalazine treatment for at least 12 months at the Second Affiliated Hospital of Wenzhou Medical University. According to simultaneous supplement of vitamin D 3 (125 IU/d), the patients were divided into study group and control group. Demographic and disease characteristics, serum 25-hydroxyvitamin D[25(OH)D] levels and other information were collected through retrieving hospital database. Student′s t-test, Mann-Whitney U test and Chi-square test were applied for comparison of disease characteristics. The changes of modified Mayo scores[ΔMayo] and 25(OH)D[Δ25(OH)D] were compared before and after treatment by paired t-test, Wilcoxon signed rank test and Chi-square test. Multiple linear regression model was used to analyze the independent factors affecting ΔMayo and Δ25(OH)D, and variables with P-values less than 0.20 in the univariate analysis were allowed for further multivariate analysis. Results:A total of 74 UC patients (44 males, 30 females), with median age (range) 39.5 (20-76) years old, were analyzed and respectively assigned into study group ( n=36) and control group ( n=38). In study group, the average level of serum 25(OH)D was significantly increased at month 12 compared with that at baseline [(22.87±7.30) μg/L vs. (18.15±7.48) μg/L, P<0.001]. However, no significant elevation of serum 25(OH)D was found in control group [(19.17±8.49) μg/L vs. (19.82±9.47) μg/L, P=0.466]. Furthermore, there was a significant decrease of modified Mayo score [-3(-4.75, -1.25) vs.-2(-3.25, 0), P=0.034] and a higher clinical remission rate (55.6% vs. 28.9%, P=0.020) at month 12 in study group than those in control group. In addition, according to the baseline level of serum 25(OH)D before mesalazine treatment, 74 UC patients were divided into vitamin D deficiency group ( n=38, serum 25(OH)D<20 μg/L) and non-deficiency group ( n=36, serum 25(OH)D≥20 μg/L). At month 12 in vitamin D deficiency group, patients with vitamin D3 supplementation had a greater decline in modified Mayo score [-4(-5.75, -2) vs.-2(-4, 0), P=0.048] and a higher clinical remission rate (60.0% vs. 22.2%, P=0.019) compared with those without. Conclusions:In patients with mild-to-moderate active UC receiving mesalazine treatment, vitamin D3 supplementation may improve the clinical efficacy, especially in patients with vitamin D deficiency.

Objective:To investigate the application value of self-pulling and latter transection (SPLT) technique in double anti-reflux double-tract reconstruction of totally laparoscopic proximal gastrectomy.Methods:The retrospective cohort study was conducted. The clinicopatholo-gical data of 103 patients with Siewert type Ⅱ adenocarcinoma of esophagogastric junction in clinical stage Ⅰ-Ⅱ who were admitted to Shanxi Cancer Hospital from January 2018 to January 2020 were collected. There were 65 males and 38 females, aged from 45 to 79 years, with a median age of 59 years. Of 103 patients, 49 cases undergoing totally laparoscopic proximal gastrectomy with double-tract reconstruction of SPLT were assigned into the SPLT group, 54 cases undergoing totally laparoscopic proximal gastrectomy with conventional double-tract reconstruction were assigned into the traditional group. Observation indicators: (1) intraoperative situations; (2) postoperative situations; (3) follow-up. Follow-up was conducted by outpatient examination and telephone inter-view to detect postoperative reflux esophagitis of patients up to December 2021. Measurement data with normal distribution were represented as Mean± SD, and the t test was used for comparison between groups. Measurement data with skewed distribution were represented as M(range) or M( Q1, Q3), and the Wilcoxon test was used for comparison between groups. Count data were described as absolute numbers or percentages, and comparison between groups was performed using the chi-square test. Comparison of ordinal data was analyzed using the non-parameter rank sum test. Results:(1) Intraoperative situations: the operation time, digestive tract reconstruction time, volume of intraoperative blood loss, the number of inferior mediastinal lymph nodes dissected, cases with auxiliary incisions for the SPLT group were (261±48)minutes, (26±4)minutes, (114±42)mL, 8.0(6.5,9.5), 1, respectively. The above indicators were (244±42)minutes, (30±6)minutes, (118±46)mL, 5.5(4.0,8.0), 9 for the traditional group, respectively. There were significant differences in the digestive tract reconstruction time, the number of inferior mediastinal lymph nodes dissected and cases with auxiliary incisions between the two groups ( t=-3.34, Z=-4.05, χ2=4.72, P<0.05). There was no significant difference in the operation time or volume of intraoperative blood loss between the two groups ( t=1.87, -0.47, P>0.05). (2) Postoperative situations: duration of postopera-tive hospital stay and cases with postoperative complications were (11.5±2.7)days and 4 for the SPLT group, versus (12.5±4.3)days and 9 for the traditional group, showing no significant difference between the two groups ( t=-1.47, χ2=1.68, P>0.05). There were 13 of 103 patients with postopera-tive complications, including 5 cases of left pleural effusion, 4 cases of anastomotic leakage, 2 cases of mild pneumonia, 1 case of incision infection, 1 case of chylous leakage. Four patients had anasto-motic leakage at the esophagojejunostomy, the abdominal esophagus of whom was invaded by more than 1 cm. During the operation, mediastinal drainage tubes were placed through the abdominal wall. The 4 patients were cured after enteral and parenteral nutrition support and adequate drainage, and the remaining patients with complications were cured after symptomatic treatment. (3) Follow-up: of 49 patients in the SPLT group, 43 cases were followed up for (18±4)months. During the follow-up, 1 case showed reflux esophagitis by gastroscopy, with the incidence of 2.33%(1/43). Of 54 patients in the traditional group, 53 cases were followed up for (17±4)months. During the follow-up, 4 cases showed reflux esophagitis by gastroscopy, with the incidence of 7.55%(4/53). There was no significant difference in the incidence of reflux esophagitis between the two groups ( χ2=0.47, P>0.05). Conclusions:SPLT technology is feasible for double anti-reflux double-tract reconstruction of proximal gastrectomy. Compared with traditional double-tract reconstruction of totally laparos-copic proximal gastrectomy, SPLT technology can reduce the auxiliary incisions, increase the number of lower mediastinal lymph nodes dissected, and shorten the digestive tract reconstruction time.
