OBJECTIVETo explore the feasibility and safety of transvaginal external fascia trachelectomy to conservatively treat patients with stage Ia1 squamous carcinoma of the uterine cervix (SCC) and cervical intraepithelial neoplasia (CIN) III, who are not suitable to take cold knife conization (CKC).

METHODSFrom July 2002 to September 2010, those patients who had a strong desire to preserve the uterus or fertility but also are confronted with following situations received transvaginal external fascia trachelectomy: CIN III with large area lesion (colposcopically observed lesion area was larger than 3/4 of the cervix), or patients with CIN II-III suffered recurrence or had persistent lesion or positive margin after CKC or LEEP, or patients with CIN II-III upgraded into stage Ia1 SCC through LEEP and pathological confirmation (except for those with lymphovascular space invasion), or CIN III patients complicated with upper vaginal intraepithelial neoplasia (VAIN). Their clinical information and data were reviewed and analyzed.

RESULTSAmong the 79 cases, who underwent transvaginal external fascia trachelectomy, six were stage Ia1 SCC, 61 were CIN III with a large area lesion (23 cases had glandular involvement), three were CIN III complicated with VAIN, six were CIN III with persistent lesion after LEEP, two were CIN III with positive margins after LEEP, and one case had recurrence after conization. The median age of these patients was 33 years old, ranging from 23 to 40 years old. The mean operation time was 39 min (rang 20-60 min), the average amount of bleeding was 40 ml (rang 1-300 ml) and the mean hospital stay was 10 d ( rang 6-17 d). The CIN III patients complicated with VAIN received this surgery with resection of the adjacent vaginal mucosa more than 2 cm in 3.8% (3/79). The median follow-up time was 49 months (8-85 months) and none of these patients had ureteral injury or large amount of intraoperative or postoperative bleeding or post-operative recurrence. No patient complained any effect on their sexual life. Among the five patients with reproductive desire, one was at her 22 w gestation after one induced abortion and one spontaneous abortion, four patients experienced term birth in which three were cesarean section and one was natural labour.

CONCLUSIONSTransvaginal external fascia trachelectomy is a safe and effective conservative treatment for stage Ia1 SCC, CIN III with large area lesion, CIN III complicated with VAIN and CIN II-III suffering recurrence, persistent lesion or positive margins after CKC and others that are not suitable to take CKC.

Objective To observe the clinical efficacy of needling method of regulating spleen-stomach in treating early-stage type 2 diabetic foot (DF).Method A hundred patients with early-stage type 2 DF were randomized into a treatment group and a control group,50 cases each.The two groups both received conventional treatment for diabetes.In addition,the treatment group was intervened by needling method of regulating spleen-stomach;the control group was given oral administration of Pancreatic kininogenase enteric-coated tablets.After 6-week treatment,the changes in fasting blood glucose (FBG),2-hour postprandial blood glucose (P2hBG),serum total cholesterol (TC),triglyceride (TG),6-keto-PGF1α and thromboxane B2 (TXB2) contents were observed.The clinical efficacies of the two groups were also compared.Result The total effective rate was 91.8％ in the treatment group versus 75.5％ in the control group,and the between-group difference was statistically significant (P＜0.05).The levels of FBG,P2hBG,TC,TG,6-keto-PGF1α and TXB2 were significantly changed after the intervention in the two groups (P＜0.01,P＜0.05).The treatment group was significantly different from the control group in comparing each parameter after the intervention (P＜0.01,P＜0.05).Conclusion Needling method of regulating spleen-stomach is an effective method in treating early-stage type 2 DF,and can improve the progressive injury induced by abnormal glucose metabolism.

Breast cancer has the highest incidence rate among all women's malignant tumors worldwide.Surgery,radiotherapy and chemotherapy are three major treatments,while most patients showed adverse effects or complications during or after the treatment,including lymphedema,gastrointestinal reactions and leukopenia,which cause severe impact on patients' recovery and quality of life.Moxibustion has been used and certified to alleviate adverse effects of surgery or chemoradiotherapy for breast cancer.We have summarized literatures in recent years and suggest more systematic research in the future for the underlying mechanism.

Objective To compare the effectiveness of TiRobot assisted F screw technique and inverted triangle parallel nail internal fixation in the treatment of unstable femoral neck fractures.Methods A retrospective analysis was conducted on 72 patients with unstable femoral neck fractures who were treated with percutaneous cannulated screw fixation assisted with TiRobot Orthopaedic robot from December 2019 to April 2021.Among them,37 patients were treated with F screw internal fixa-tion,including 16 males and 21 females,aged47 to 64years old with an average of(53.87±5.28)years old;According to Pauwels classification,there were 1 case of type Ⅰ,19 cases of type Ⅱ,17 cases of type Ⅲ;8 cases of combined medical diseases;17 cases of falling,8 cases of traffic accident and 12 cases of falling from height;The time from injury to operation was 29 to 49 hours with average of(35.00±7.34)hours.Another 35 cases used internal fixation with an inverted triangle parallel nail,including 13 males and 22 females with an average age of 46 to 63 years old(52.36±5.05)years old;According to the Pauwels injury classifi-cation:there were 2 cases of type Ⅰ,21 cases of type Ⅱ,12 cases of type Ⅲ;6 cases of medical diseases,15 cases of falling in-jury,9 cases of traffic accident,11 cases of falling injury;The time from injury to operation was 30 to 45 hours with an average of(33.00±6.83)h.The intraoperative blood loss,operation time,intraoperative fluoroscopy times,follow-up time,fracture healing time,postoperative complications were observed and compared between the two groups.The hip joint function was e-valuated by Harris score at 6 months and 12 months after operation.Results There was no significant difference in operation time,intraoperative blood loss,intraoperative fluoroscopy times and other intraoperative data between two groups(P＞0.05).Both groups were followed up regularly,and the follow-up time was 12 to 16 months.The fracture healing time and Harris score of the F screw internal fixation group were better than those of the inverted triangle parallel nail internal fixation group(P＜0.05).There was 1 case of femoral neck shortening in the F screw internal fixation group,1 case of nonunion,1 case of nail withdrawal,and 1 case of lower extremity deep vein thrombosis in the inverted triangle internal fixation group.The incidence of complications in the F screw internal fixation group was lower than that in the inverted triangle parallel nail internal fixation group(P＜0.05).Conclusion Percutaneous cannulated F screw technique using Tirobot navigation positioning system is a safe and effective treatment for patients with unstable femoral neck fractures.It can significantly shorten the fracture healing time,reduce the incidence of postoperative complications,significantly improve hip joint function,and improve the quality of life.

OBJECTIVETo evaluate the effects of Tanguticum Maxim polysaccharide (TMP-1) on TNBS-induced colitis in rats.

METHODRats with TNBS/ethanol-induced colitis were used and treated with TMP-1 and dexamethasone (DX). Seventy-two rats, including animals with TNBS-induced colitis, were treated with saline, TMP-1 (100, 200, 400 mg.kg-1) and DX. White blood cells were counted on the fifth day and the rats were killed by ether on the sixth day. SOD activity in serum, MPO and SOD activity of colonic tissue were measured.

RESULTThe remarkable effects of TMP-1 at dosage of 200, 400 mg.kg-1 on TNBS-induced colitis were observed. The ulcerative area was diminished and weight of colon was reduced. White blood cell population was reduced, SOD activity in serum and SOD activity of colon tissue were remarkably increased, and, MPO activity of colonic tissue was reduced.

CONCLUSIONTMP-1 has significant effects on TNBS-induced colitis in rats with lower side effects, which suggests the effective component of rhubarb on colitis perhaps is TMP. The mechanism of the actions of TMP may relate to its antiflammation, antioxidation and immunoloregulation.

Objective:To observe the clinical effect of acupuncture for persistent allergic rhinitis (PAR).Methods:A total of 154 PAR patients were randomized into a treatment group and a control group,78 cases in the treatment group received acupuncture at meridian points,while 76 cases in the control group received acupuncture at non-meridian points.The treatment was done every other day,3 times a week for a total 4 weeks.The total nasal symptom score (TNSS),the total non-nasal symptom score (TNNSS) and the rhinoconjunctivitis quality of life questionnaire (RQLQ) were measured before the treatment and after 2 weeks and 4 weeks of treatment,as well as 1 month and 3 months after the treatment to compare the clinical effect between the two groups.Results:After 4 weeks of treatment,the total effective rate in the treatment group was 92.3％,versus 76.3％ in the control group,showing a statistically significant difference (P＜0.05).Intra-group comparisons of TNSS,TNNSS and RQLQ scores after 4 weeks of treatment showed statistically significant differences (all P＜0.05).Between-group comparisons of TNSS,TNNSS and RQLQ score after 4 weeks of treatment and in follow-up visits showed statistically significant differences (all P＜0.05).Conclusion:Acupuncture is effective for PAR,and acupuncture at meridian points can produce a better effect than acupuncture at non-meridian points.

Objective:To analyze the activation characteristics of trapezius muscle in normal people, and explore whether different interventions could restore the activation pattern of people with abnormal trapezius muscles to normal during subsequent exercises. Methods:From September to October, 2017, 20 persons with normal shoulder joints (control group) and 20 persons with mild discomfort in shoulder joints (observation group) participated in the study. All of them were treated randomly with four steps, including no intervention, static traction of upper trapezius muscle (UT), isometric contraction of lower trapezius muscle (LT) and combined intervention. Then, they were asked to complete three actions, including straight arm side lifting, sitting in rowing and flying birds. Myoelectric signal was recorded before and after test. Results:Compared with the control group, the UT activation degree increased (P < 0.05), and the activation time shortened (P < 0.05); the activation degrees of middle trapezius muscle (MT) and LT decreased (P < 0.05), and the activation time delayed (P < 0.05); the ratios of UT/LT and UT/MT increased (P < 0.05) in the observation group with no intervention. After static traction of UT, isometric contraction of LT, and both interventions, the MVE%, activation time and the ratios of activation varied in different muscles under different actions in both groups (P < 0.05). Conclusion:In different actions, the activation degree and activation time of three trapezius muscles are different. Static traction of UT and isometric contraction of LT before exercise could improve the activation pattern of trapezius muscles of people with shoulder joint discomfort during exercise, which is conducive to the normal function of the shoulder joint.

OBJECTIVE: To establish the cell model of human neuroblastoma cell( SH-SY5Y cell) exposed to1,2-dichloroethane( 1,2-DCE) in vitro and to explore the mechanism of 1,2-DCE-induced toxicity in SH-SY5Y cells.METHODS: SH-SY5Y cells were collected in their logarithmic growth phase and cultured in complete medium that had final concentrations of 1,2-DCE in 0,10,20,30,40,50,60,70 and 80 mmol / L for 24 hours. Cell morphology was observed and cell survival rate was examined by CCK-8 assay. Using chemical colorimetric method, the activity of lactic dehydrogenase( LDH) in the cell culture supernatant,and the intracellular level of malondialdehyde( MDA),the intracellular activities of superoxide dismutase( SOD) and adenosine triphosphate( ATP) enzymes were detected. RESULTS: With the increasing exposure concentrations of 1,2-DCE,the cell density of SH-SY5Y cells gradually decreased,the synapse became shorter,the membrane ruptured,cytoplasm condensed and cytoplasmic contents overflowed increased.With the increasing concentration of 1,2-DCE,the cell survival rate decreased( P < 0. 01),the activity of LDH in the cell culture supernatant increased( P < 0. 01). These changes had a dose-effect correlation. Intracellular MDA level,and activities of SOD,Na~+-K~+-ATP enzyme,Ca~(2+)-Mg~(2+)-ATP enzyme and total ATP enzyme increased at first and then decreased. The activity of LDH in the cell culture supernatant and cell survival rate was negatively correlated( the correlation coefficient is- 0. 907,P < 0. 01). CONCLUSION: 1,2-DCE could inhibit the proliferation of SH-SY5Y cells.The mechanism may be related to the permeability change of cell membrane,cellular damage from excessive free radicals,the decrease of free radical scavenging capacity,ATP enzyme activity and calcium overloading. SH-SY5Y cells can be used as a common cell line for 1,2-DCE cytotoxicity analysis.

OBJECTIVETo investigate the effect of Dan-gua Fang on adenosine 5'-monophosphate (AMP) activated protein kinase (AMPK) α expression in liver and subsequent improvement of glucose and lipid metabolism.

METHODSForty 13-week-old diabetic Goto-Kakizaki (GK) rats were randomly divided into model, Dan-gua Fang, metformin and simvastatin groups (n=10 for each), and fed high-fat diet ad libitum. Ten Wistar rats were used as normal group and fed normal diet. After 24 weeks, liver expression of AMPKα mRNA was assessed by real-time PCR. AMPKα and phospho-AMPKα protein expression in liver was evaluated by Western blot. Liver histomorphology was carried out after hematoxylin-eosin staining, and blood glucose (BG), glycosylated hemoglobin A1c (HbA1c), food intake and body weight recorded.

RESULTSSimilar AMPKα mRNA levels were found in the Dan-gua Fang group and normal group, slightly higher than the values obtained for the remaining groups (P<0.05). AMPKα protein expression in the Dan-gua Fang group animals was similar to other diabetic rats, whereas phospho-AMPKα (Thr-172) protein levels were markedly higher than in the metformin group and simvastatin group (P<0.05), respectively. However, phosphor-AMPKα/AMPKα ratios were similar in all groups. Dan-gua Fang reduced fasting blood glucose with similar strength to metformin, and was superior in reducing cholesterol, triglycerides, high-density lipoprotein cholesterol as well as improving low-density lipoprotein cholesterol in comparison with simvastatin and metformin. Dan-gua Fang decreases plasma alanine aminotransferase (ALT) significantly.

CONCLUSIONDan-gua Fang, while treating phlegm-stasis, could decrease BG and lipid in type 2 diabetic GK rats fed with high-fat diet, and effectively protect liver histomorphology and function. This may be partly explained by increased AMPK expression in liver. Therefore, Dan-gua Fang might be an ideal drug for comprehensive intervention for glucose and lipid metabolism disorders in type 2 diabetes mellitus.
