The PCR products were inserted into pEASY-T5 vector, transfected E.coli, identified and sequenced.The PGC-1αgene expression in different tissues of the Bama mini-pigs was detected by RT-PCR and QRT-PCR assays.Results The PGC-1αgene CDS of Guangxi Bama mini-pig was cloned.It was 2391 bp in length.It had 99.9%homology with the reference sequence, and had two synonymous mutations that were C-A1105 and G-A1524.The expression level of PGC-1αgene was higher in the heart and kidney, followed by liver, subcutaneous fat and longissimus muscle, but the expression was not de-tected in pancreas of Guangxi Bama mini-pig.Conclusions We have successfully cloned the PGC-1αgene of Guangxi Bama mini-pig, and detected this gene expression in six tissues.The results of this study will provide a basis for studying the effect of PGC-1αon type 2 diabetes mellitus (T2DM) in Bama mini-pigs.

Objective:To investigate the clinical effect of the first dorsal metatarsal-dorsal phalangeal artery flap in repairing large area of soft tissue defect on the palmar side of finger.Methods:From February, 2016 to June, 2018, 11 fingers of 11 patients (7 males and 4 females, aged 19-46 years old with an average of 32.5 years old) with large area of soft tissue defect on the palmar side of the finger were repaired with the first dorsal metatarsal-dorsal phalangeal artery flap. These included 3 with the first dorsal metatarsal-first dorsal phalangeal artery blood supply, and 8 with the first dorsal metatarsal-second dorsal phalangeal artery blood supply. In which 3 with retained finger pulp was for repairing the defects and bridging arteries, including 1 flexor tendon defect repaired by the extensor digitorum brevis tendon of the second toe with the flap. The type of blood vessel was Gilbert I detected by CDU before surgery. The area of the flaps was from 1.5 cm×5.0 cm to 3.0 cm×8.0 cm. The donor area of the flaps was compressed with full thickness skin grafts of the shank. The follow-up data was collected by outpatient clinic visits and telephone interviews.Results:All the 11 flaps survived and were followed-up for an average of 14 months, ranged from 6 months to 24 months. The colour and texture of the flaps were good. Sensing of temperature, pain and touch restored, without swelling. Function of the fingers was well restored. The range of motion of distal and proximal interphalangeal joints was closed to normal. The TPD of the flaps was 5-11 mm, with an average of 8 mm. Ten had primary wound healing in the donor sites of foot. One case had necrosis of the proximal toe of the skin graft and healed after dressing change. Long-term follow-up of the skin grafting area was wear-resistant, and does not hinder walking without rupture.Conclusion:Application of the first dorsal metatarsal-dorsal toe artery flap to repair large area of soft tissue defect on the palmar side of finger has number of advantages such as it, covers the wound and carry the tendons, bridges the arteries at the same time, plus delivers satisfactory outcome.

Objective To observe the effects of electro-acupuncture (EA) on body weight, insulin resistance, hypothalamic agouti gene-related protein (AGRP) and neuropeptide Y (NPY) in diet induced obesity (DIO) rats; To discuss its mechanism for DIO.Methods Fifty SD male rats were randomly divided into low fat diet groups (LFD) and high fat diet group. After the DIO models were established, the successful model rats were randomly divided into model group, EA group and Orlistat (OLST) group. EA was applied to “Zusanli” (ST36) and “Quchi” (LI11) for 20 minutes. The treatment was done once a day for 28 days. OLST was treated with orlistat by gavage. LFD and model did not receive treatment. Body weight was recorded every day. FPG and FINS were detected. The expressions of AGRP and NPY were detected by RT-QPCR. Morphological changes of adipocyte and liver were examined by HE staining.Results The body weight, HOMA-IR, AGRP, NPY and diameter of adipocyte of EA group and OLST group were significantly lower than model group (P<0.05), difference between EA group and OLST group. The states of hepatic steatosis were improved in EA group and OLST group.Conclusion EA has the effects on weight loss by inhibiting the expressions of AGRP and NPY by improving IR.

ObjectiveTo observe the clinical efficacy of modified Shenqi Pill （肾气丸） plus Tongdu Tiaoshen Acupuncture （通督调神针刺） in the treatment of neurogenic bladder after spinal cord injury of kidney-yang deficiency syndrome. MethodsForty-six patients were randomly divided into 23 cases each in the control group and the treatment group. Both groups were given conventional treatment， i.e. oral methylcobalamin tablets （0.5 mg each time， 3 times a day） and paraplegic conventional acupuncture （once a day， 6 consecutive days a week）. The control group was given simple bladder function rehabilitation training on the basis of the conventional treatment； and the treatment group was given modified Shenqi Pill orally （1 dose a day， 150 ml each time， taken warmly in morning and evening） and Tongdu Tiaoshen Acupuncture （once a day， 6 consecutive days per week） in addition to what were given to the control group. The treatment course lasted for 4 weeks. The 24 h urination frequency， 24 h urine leakage frequency， 24 h single urine volume， bladder residual urine volume， international lower urinary tract symptom （LUTS） score， traditional Chinese medicine （TCM） syndrome score were compared between the two groups， and clinical effectiveness and TCM syndrome effectiveness were compared between the two groups after treatment. ResultsTwenty patients in each group were finally analyzed in this study. The number of 24 h urination， the number of 24 h urine leakage， bladder residual urine volume， LUTS score， and the TCM syndrome scores decreased after treatment in both groups， and the 24 h single urine volume increased （P＜0.01）； and much more improvement was found of each index in the treatment group than in the control group （P＜0.05 or P＜0.01）. The total clinical effectiveness and TCM syndrome effectiveness in the treatment group was 85.00% （17/20） respectively， which were statistically significantly higher than 45.00% （the total clinical effectiveness， 9/20） and 60.00% （TCM syndrome effectiveness， 12/20） in the control group （P＜0.01）. ConclusionModified Shenqi Pill plus Tongdu Tiaoshen Acupuncture can signi-ficantly improve the clinical symptoms of neurogenic bladder patients after spinal cord injury of kidney-yang deficiency syndrome， having better effectiveness than simple bladder function rehabilitation training， and its mechanism may be related to the improvement of the injured nerve function innervating the bladder.

Methods: The flap on tibial of second toe was designed according to the size of defect. The pedicle of the flap is the tibial proper plantar digital artery of the toe, and the rotation point is located between the toe web.13 cases of the great toe′s defects were repaired by this method, with the donor sites covered by full thickness skin from the leg. Results: 13 flaps survived postoperatively. All cases were subject to postoperative follow-up, follow-up time was 6-48 months, an average of 18 months. Skin color and texture was close to that of the surrounding tissues, appearance is not bloated. Conclusions The second toe lateral skin flap is easy to operate, is flexible for rotating. As local material, it is an ideal skin flap to repair the great toe defect.

Objective To explore the application and clinical effect of blood bridge venous flap in finger wound with proper palmar digital artery defect. Methods From February,2007 to September,2016,11 cases of fin-ger wound with artery defect were repaired with forearm vein free flap by the way of bridging blood vessels. The time from injury to surgery was 1.5 to 6 hours(average 2.5 hours).Vascular defect length was 1.4 to 3.4 cm(average 2.3 cm). 8 cases were bridged the unilateral digital artery and 3 cases were bridged the both side. The area of skin flap was 1.5 cm × 2.0 cm to 2.2 cm × 3.5 cm and the donor site was sutured directly. Results One case appeared necrosis in marginal part and healed after dressing change. The other flaps and finger survived and the incisions healed well.All the 11 cases were followed up after operation. The follow-up time ranged from 6 to 20 months, aver-aged 10 months. The color and texture were well,the sensation of temperature, pain and tactile were recovered, and the flap had good contour. According to TAM system evaluation method: 6 cases got excellent results,4 cases were good,1 case was poor. The donor site only had a linear scar and the flexion and extension of wrist were not limited. Conclusion Flow bridging venous flap can reconstruct the finger blood and repair the wound simultaneously. To the finger with nerve or tendon defect,bridged with the cutaneous nerve or palmaris longus tendon can also get satisfactory result.

Objective: To investigate the effect of oral nutritional supplements(ONS) on body weight loss and life quality in post-discharge patients with gastric and colorectal cancer. Methods: All the enrolled post-operative gastric or colorectal cancer patients were randomly divided into ONS group and control group. Body weight loss, middle arm circumference, triceps skinfold thickness and right-hand grip strength were measured and the Karnofsky score, ECOG score and QOL score were calculated 3 months after the discharge. Results: The body weight loss of gastric cancer patients was lower in ONS group than in control group since 2 months after discharge.(2 months after discharge: 1.65±2.11vs. 2.70±1.90 kg, t=-2.385 3, P=0.019 3; 3 months after discharge: 1.95±2.75vs. 3.67±2.29 kg, t=-3.134 7, P=0.002 4), There was no difference of body weight loss between two groups in colorectal cancer patients. The middle arm circumference, triceps skinfold thicknessand right-hand grip strength showed no statistic difference between two groups both in gastric and colorectal cancer patients. The Karnofsky score(56.82±13.65%vs. 51.71±9.72%, t=2.014 8, P=0.047 2) and QOL score(41.91±6.92 vs. 38.39±8.77, t=2.059 7, P=0.042 6) were higher in ONS group than in control group in gastric cancer patients. While all 3 types of scores had no difference between two groups in colorectal cancer patients. Conclusion ONS can efficiently reduce the body weight loss and improve the performance status and life qualityin post-discharge gastric cancer patients, but not in colorectal cancer patients.

Objective:To study the safety and efficacy of laparoscopic cholecystectomy (LC) in treatment of T2a and lower stages of gallbladder carcinoma.Methods:A retrospective study was performed on patients who were diagnosed with gallbladder cancer and underwent surgical treatment from January 2016 to January 2021 at Hunan Provincial People's Hospital. These patients were divided into the simple treatment group and the radical treatment group based on the surgical methods used. The simple treatment group consisted of 64 patients who underwent LC for accidental gallbladder cancers. The radical treatment group consisted of 30 patients who underwent laparoscopic radical cholecystectomy (LRC). The baseline characteristic of the two groups of patients were matched in a 1∶1 ratio using propensity score matching. After matching, there were 26 patients in each of the 2 groups. There were 7 males and 19 females in the simple group, with mean ± s. d. age of (60.6±9.6) years. There were 8 males and 18 females, with mean ± s. d. age (60.9±9.1) years in the radical treatment group. Blood loss, operation time, postoperative hospital stay, biliary leakage, acute pulmonary embolism, and incisional infection were compared between the two groups.Results:In the simple group, the operative time was (78.7±62.9) min, intraoperative blood loss was (10.7±11.6) ml and postoperative hospital stay was (4.4±2.6) d. These results were significantly better than those in the radical group with operative time (298.7±101.3) min, intraoperative blood loss (161.9±96.7) ml and postoperative hospital stay (9.9±4.0) d (all P<0.05). There were no significant difference in the postoperative complications and disease free survival rates between the two groups (both P>0.05). Conclusion:LC was safe and effective for treatment of T2a and lower stages of gallbladder cancer, and it could achieve a similar disease-free survival rate as LRC.

This case report focused on a patient with supraeruption of the first and second mandibular molars as a result of loss of the first and second maxillary molars for a long time. We adopted a combination of a vacuum-formed removable appliance and elastics to intrude the first and second mandibular molars by using a continuous, light force to acquire sufficient restoration space for maxillary molars. Thus, the dental-implant treatment was successful, and a good and stable occlusal relationship was established.
