Diabetic kidney disease （DKD） is a kidney disease caused by hyperglycemia，which is one of the most common microvascular complications of diabetes. Due to the high incidence of diabetes，the incidence of DKD has also increased year by year，and DKD has become a global public health problem. The pathogenesis of DKD is related to mechanisms such as oxidative stress，inflammation，renal fibrosis，and decreased mitophagy activity，which are developed under a variety of complex mechanisms. In traditional Chinese medicine，it is believed that the incidence of DKD is closely related to damp heat. Therefore，it is necessary to grasp the treatment method of clearing heat and removing dampness in clinical medication. Huangkui Capsules （HKC） have the effect of clearing damp heat，detoxifying， and detumescence. Because of its unique curative effect on DKD，HKC is often used in the treatment of DKD. HKC plays a role in the treatment of DKD with a variety of pharmacokinetic and pharmacodynamic processes. In many laboratory studies，it has been found that the specific mechanisms of HKC in the treatment of DKD include increasing mitophagy，reducing mitochondrial damage，reducing renal fibrosis，controlling inflammatory response，and inhibiting oxidative stress，which can achieve the purpose of reducing renal damage and promoting renal function. Some clinical studies have also verified that the application of HKC alone can exert renal protective function through anti-inflammatory，anti-oxidative stress，anti-renal fibrosis effects，as well as reduction of urinary protein. Since DKD is not a single injury of renal function，it is often accompanied by problems in blood pressure，blood lipids，blood circulation，body immunity， and other aspects. Therefore，the combination of HKC with other drugs can often achieve more comprehensive results，improve the advantages of various drugs，and improve the therapeutic effect. The combination of drugs such as antihypertensive，lipid-lowering， vascular circulation improvement，immunity inhibition，and anti-oxidative stress with HKC has achieved good results. In addition，HKC is often used in combination with other Chinese patent medicines in clinics. The application of HKC in the treatment of DKD has made some progress，but there are still many places worthy of further study，and the research on the mechanism of HKC is not comprehensive enough. The research on its long-term effect and safety in clinical application is relatively lacking，and the drug variety is relatively single when combined with certain drugs. These problems deserve further attention. Finally，it is necessary to pay attention to the promotion and application of HKC in clinical practice so that HKC can be better applied in clinical practice and better solve practical problems for patients.

OBJECTIVE: To explore method and clinical effect of microsurgical thinned anterolateral thigh perforator flap to repair soft tissue defects of foot and ankle. METHODS: From March 2017 to January 2022, totally 20 patients with soft tissue defects of ankle joint were treated with micro-thinning anterolateral perforator flap for free transplantation, included 13 males and 7 females, aged from 22 to 58 years old with an average of (36.45±12.36) years old. The size of flap ranged from 8.0 cm×5.0 cm to 20.0 cm×12.0 cm. Before operation, perforating vessels on the anterolateral thigh region were detected and marked with a portable Doppler detector. For the defect width less than 8 cm, 11 patients were repaired with a single flap. For the defect width more than 8 cm, the wound could not be sutured directly, and the lobulated flap technique was used in 9 patients, the width was converted to length, and the donor site was closed directly. Under the microscope, all flaps were thinened in a stepwise manner from the center of the pedicle to the periphery. After operation, survival of the flap, the shape, texture, sensory function recovery were observes, and recovery of foot function was evaluated by Maryland foot function evaluation standard. RESULTS: All 20 patients with microsurgical thinned anterolateral thigh perforator flaps were survived. Venous crisis occurred in 1 patient due to subcutaneous hematoma, after removal of the hematoma, the crisis was relieved and the flap survived successfully. The wounds in the donor and recipient sites healed well, and only linear scars left in the donor sites. Twenty patients were followed up for 3 to 26 months after operation, good shape of flaps without bloated, and good texture. The two-point discrimination of free flaps ranged from 9.0 to 16.0 mm, and the protective sensation was restored. The ankle flexion and extension function recovered well and patients could walk normally. According to Maryland foot function evaluation standard, 8 patients got excellent result, 10 patients good and 2 middle. CONCLUSION Microsurgical thinned anterolateral thigh perforator flap is an ideal method to repair soft tissue defects in functional area of foot and ankle, with good appearance and texture of the flap, no need for re-plastic surgery, reduced hospitalization costs, and less donor site damage.

Objective:To select and evaluate new Chinese herbal prescription for the treatment of decreased ovarian reserve （DOR） and its appropriate dosage. Method:The literature concerning the treatment of DOR with traditional Chinese medicine （TCM） was retrieved from such databases as Chinese Journal Full-text Database， Wanfang Data Knowledge Service Platform， and Chongqing Weipu Database for Chinese Technical Periodicals （VIP）， based on which a database was established using the Traditional Chinese Medicine Inheritance Support System （TCMISS） V2.5. The data mining was then carried out to obtain the core combinations of Chinese herbs and new Chinese herbal prescription combinations， followed by the determination of the new Chinese herbal prescription by expert group discussion for experiment evaluation. The female SD rats were divided into the normal group， DOR model group， Kuntai capsule group， and low-， medium-， and high-dose new Chinese herbal prescription groups， with 12 rats in each group. Rats in the Kuntai capsule group and low-， medium-， and high-dose new Chinese herbal prescription groups were treated with Kuntai capsule solution （0.5 g·kg^-1 determined according to the dosage in the instruction） and 3.037 5， 6.075， and 9.12 g·kg^-1 new Chinese herbal prescription， respectively. After 21 days， the estrous cycle was observed by vaginal exfoliated cell smear， and the ovarian structure was observed by hematoxylin-eosin （HE） staining. The serum anti-mullerian hormone （AMH）， follicle stimulating hormone （FSH）， luteinizing hormone （LH）， and estrogen （E₂） contents as well as the reactive oxygen species （ROS）， malondialdehyde （MDA）， and glutathione （GSH） levels and superoxide dismutase （SOD）， catalase （CAT）， and glutathione peroxidase （GSH-Px） activities in ovary were detected using biochemical methods. Result:The new Chinese herbal prescription subjected to experimental evaluation was composed of 11 Chinese herbs， namely Rehmanniae Radix Praeparata 20 g， Cervi Cornus Colla 12 g， Lycii Fructus 20 g， Corni Fructus 12 g， Albiziae Cortex 9 g， Nelumbinis Plumula 3 g， Salviae Miltiorrhizae Radix et Rhizoma 20 g， Astragali Radix 30 g， Atractylodis Macrocephalae Rhizoma 12 g， Dioscoreae Rhizoma 30 g， and Glycyrrhizae Radix et Rhizoma Praeparata Cum Melle 6 g. Compared with the model group， the Kuntai capsule group and medium- and high-dose new Chinese herbal prescription groups exhibited significantly improved estrous cycle and follicular development， elevated serum AMH and E₂ and ovarian GSH （P<0.05）， decreased serum FSH and LH （P<0.05） and ovarian ROS and MDA （P<0.05）， and enhanced SOD， CAT， and GSH-Px activities （P<0.05）. There were no significant differences in the above-mentioned indexes between the Kuntai capsule group and the middle- and high-dose new Chinese herbal prescription groups， but the estrous cycle and follicular development were better in the latter two groups. Conclusion:The new Chinese herbal prescription screened by data mining is able to enhance ovarian antioxidation， promote follicular development， ameliorate serum hormone and estrous cycle， and effectively improve ovarian reserve function in DOR rats. The medium dose （6.075 g·kg^-1） has been proved optimal.

Objective:To observe the improving effect of Danggui Shaoyaosan on diminished ovarian reserve （DOR） in rats triggered by Tripterygia wilfordii polyglycoside tablet combined with stress， and to explore the role of transforming growth factor-β₁ （TGF-β₁）/Smads signaling pathway in such improvement. Method:Forty-eight female SD rats with normal sexual cycle were selected and randomly divided into a normal group （n=8） and a modeling group （n=40）， and the ones in the modeling group were given Tripterygium wilfordii polyglycoside tablets （50 mg·kg^-1） combined with random stress for 15 d. After successful modeling， the rats were randomized into the model group， low-， medium-， and high-dose （3.96， 7.92， 15.84 g·kg^-1） Danggui Shaoyaosan groups， and estradiol valerate group （0.09 mg·kg^-1）， with eight in each group. Under the premise of stress exposure， they were separately gavaged with the normal saline， low-， medium- and high-dose Danggui Shaoyaosan， and estradiol valerate for 15 successive days. The estrous cycle of rats in each group was observed daily. After intervention， the rats were sacrificed and the ovarian visceral index was calculated. The pathological changes in ovarian tissues were observed by hematoxylin eosin （HE） staining. The protein expression levels of TGF-β₁ and TGF-β₁ receptor （TGF-β₁R） in the ovarian tissues of rats were measured by immunohistochemistry （IHC）， and the mRNA expression levels of Smad2， Smad3， and Smad7 in the ovarian tissues by real-time polymerase chain reaction （Real-time PCR）. Result:Compared with the normal group， the model group exhibited disordered estrus cycle （P<0.05）， reduced visceral index （P<0.01）， and down-regulated TGF-β₁ and TGF-β₁R protein and Smad2 and Smad3 mRNA expression in the ovarian tissues （P<0.01）， and up-regulated Smad7 mRNA expression （P<0.01）. Compared with the model group， Danggui Shaoyaosan at the low， medium， and high doses and estradiol valerate improved the estrus cycle of rats to varying degrees （P<0.05） and increased the visceral index， with better effects observed in the medium-group and high-dose Danggui Shaoyaosan groups （P<0.05，P<0.01）. Besides， the protein expression levels of TGF-β₁ and TGF-β₁R and the mRNA expression levels of Smad2 and Smad3 in the ovarian tissues were elevated to varying degrees （P<0.01）， and the Smad7 mRNA expression declined （P<0.01）. The improvements in TGF-β₁ and TGF-β₁R protein expression of the medium-dose Danggui Shaoyaosan group and estradiol valerate group were more obvious. Conclusion:Danggui Shaoyaosan significantly improves ovarian reserve in DOR rats， which is closely related to the regulation of TGF-β₁/Smads signaling pathway.

OBJECTIVETo compare the effects of moxibustion combined with highly active antiretroviral therapy (HAART) and simple HAART for human immunodeficiency virus (HIV) infected patients.

METHODSA total of 100 patients with HIV receiving HAART were randomized into an observation group and a control group, 50 cases in each one. In the observation group, moxibustion was used at Zusanli (ST 36), Guanyuan (CV 4) and Sanyinjiao (SP 6), etc. combined with HAART of zidovudine, lamivudine, nevirapine and efavirenzone, etc. Simple HAART was used in the control group. The patients were observed for 18 months. The indexes were CD, CD/CD, interleukin 2 (IL-2), interleukin 7 (IL-7), the incidence of side effects and the score of quality of life.

RESULTSAfter treatment, CD, CD/CD, serum IL-2 and the scores of quality of life (physiological, psychological, social relation fields and comprehensive score) increased and serum IL-7 decreased compared with those before treatment in the two groups (<0.01,<0.05), with better results except CDin the observation group (<0.01,<0.05). The incidences of gastrointestinal side effects and total side effects in the observation group were lower than those in the control group (14% (7/50) vs 32% (16/50), 58% (29/50) vs 80% (40/50), both<0.05).

CONCLUSIONMoxibustion combined with HAART for HIV infected patients could reduce the incidence of side effects, improve medication compliance, CD/CD, IL-2, IL-7 and the quality of life.

Objective: To evaluate the short-term and long-term outcomes after laparoscopic surgery compared with traditional laparotomy in cases of stage ⅠA2-ⅡA2 cervical cancer. Methods: We conducted a retrospective study on the clinical data of 1 863 patients diagnosed as FIGO stages ⅠA2-ⅡA2 cervical cancer in 6 third-grade class-A hospitals in Guangxi province between January 2007 and May 2014. One thousand and seventy-one received laparoscopy, and 792 received laparotomy. T-test, U-test and χ² test were used to compare the short-term and long-term outcomes. The short-term outcomes included surgical related outcomes and operative complications, and the long-term outcomes included quality of life (pelvic floor functions and sexual functions), survival and recurrence. Pelvic floor function and sexual function were assessed with the International Consultation on Incontinence Quesonnaire Female Lower Urinary tract(ICIQ-FLUTS) and the Female Sexual Function Inventory (FSFI), respectively. Survival rates were estimated by Kaplan-Meier analysis. The survival curves were compared with Log-rank test. Cox regression analysis was used to evaluaterisk factors for prognosis. Results: (1)The short-term outcomes : There were significant difference in operative time([(257±69) vs(238±56)min], estimated blood loss[(358±314) vs(707±431)ml], anus exhausting time[(2.5±0.9) vs (2.9±0.8)d], preserved days of catheter[(15±7) vs(18±9)d], and post-operative length of stay[(19±16) vs (30±21)d] between the laparoscopic surgery group and the opensurgery group(P<0.05). There was no significant difference in lymph nodes yielded[(21±9) vs (21±11)], left parametrial width[(2.5±0.8) vs (2.7±0.7)cm], right parametrial width [(2.6±0.3) vs (2.7±0.2)cm], vaginal cuff length[(2.4±0.7) vs (2.2±0.7)cm] between the laparoscopic surgery group and the opensurgery group(P>0.05). The intra-operative complications occurred in 8.1%(87/1 071)in the laparoscopic surgery group and in 10.7%(85/792)in the open surgery group(P>0.05). However, the complications of vascular injury in the laparoscopic surgery group[2.6%(28/1 071)]was lower than that in the open surgery group[7.7%(61/792), P<0.001]. The laparoscopic surgery exhibited lower post- operative complication rate [33.8%(362/1 071)vs 40.2%(318/792), P<0.05] and poorer wound healing rate [0.7%(7/1 071)vs 4.0%(32/792), P<0.05]. (2)The long-term outcomes(Hierarchical analysis): The overall incontinence in ICIQ-FLUTS questionnaire in nerve-sparing laparoscopic group [28.4%(67/236)] was lower than that in the open surgery group [35.9%(71/198), P=0.004] . However, There was no significant difference in degree of incontinence between the two groups(P>0.05). The overall sexual dysfunction in FSFI questionnaire after 12 months of postoperative in the nerve-sparing laparoscopic group [47.0%(111/236)]was lower than that in the open surgery group [58.6%(116/198), P=0.001], and the six different dimension scores in the laparoscopic surgery group were higher than that in the open surgery group (P<0.05). The recurrence rate was 3.5%(35/1 007)in the laparoscopicsurgery group and 4.7%(35/740)in the open surgery group(P>0.05). The 5-year OS was 94.0% for the laparoscopic surgery group and 90.2% for the open surgery group(P>0.05), and the 5-year DFS was 93.9% for the laparoscopic surgery group and 89.1% for the open surgery group(P>0.05). (3) Prognostic fators: In univariate analysis, tumor dimension, clinical stage, deep stromal invasion, LVSI, and retroperitoneal lymph node metastasis signficantly affected 5-year OS and 5-year DFS(P<0.05); In multivariate analyses, LVSI, deep stromal invasion and LN metastasis were independent prognostic factors(P<0.05). Conclusions Laparoscopy can reduceestimated blood loss, accelerate postoperative recovery and improve the quality of life after surgery compared to laparotomy, and it ensures the same oncological results as open surgery. Laparoscopic approach is a safe and effective treatment for early-stage cervical cancer.

INTRODUCTIONHead and neck squamous cell carcinoma (HNSCC) is a common cancer worldwide and has a poor prognosis. A biomarker predicting the clinical outcome of HNSCC patients could be useful in guiding treatment planning. Overexpression of the T lymphoma invasion and metastasis 1 (Tiam1) protein has been implicated in the migration and invasion of neoplasms. However, its role in HNSCC progression needs to be further validated. We detected the expression of Tiam1 in normal and tumor tissues and determined its association with clinical outcomes in patients with HNSCC.

METHODSWe measured the expression of Tiam1 in normal and cancerous tissue samples from the patients with HNSCC treated at Sun Yat-sen University Cancer Center between 2001 and 2008. The Tiam1 expression was scored from 0 to 12 based on the percentage of positively stained cells and the staining intensity. We then determined the diagnostic performance of this score in predicting overall survival (OS) and disease-free survival (DFS).

RESULTSOf the 194 evaluable patients, those with advanced disease, lymph node metastasis at diagnosis, and recurrence or metastasis during follow-up had a higher tendency of having high Tiam1 expression as compared with their counterparts (P < 0.05). The proportion of samples with high Tiam1 expression was also higher in cancerous tissues than in non-cancerous tissues (57.7% vs. 13.9%, P < 0.001). Cox proportional hazards regression analysis revealed that Tiam1 expression scores of 5 and greater independently predicted short OS and DFS.

CONCLUSIONThe Tiam1 expression is shown as a promising biomarker of clinical outcomes in patients with HNSCC and should be evaluated in prospective trials.

Objective: To explore the effect and specific mechanism of lung-tonifying and expectorant decoction on lung cancer rats with Qi deficiency and blood stasis, and aim to provide a new idea on treating the disease with traditional Chinese medicine based on syndrome differentiation. Methods: A total of 60 C57BL/6J male rats were included in the study. The model of Qi deficiency and blood stasis was established in 60 rats by using multiple-factor stimulation. About 10 rats were randomly taken to verify whether the model establishment was successful and the rest of 50 rats were divided into 5 groups with 10 rats each: blank control group, cisplatin group, low dose group, medium dose group and high dose group. The blank control group was treated with normal saline, and cisplatin group was treated with cisplatin while the other three groups were treated with lung-tonifying and expectorant decoction at different doses. The volume change in transplanted tumor, tumor inhibition rate, apoptosis rate, and expression of Bcl-2, Bax, cleaved caspase-3 and cleaved caspase-9 in 5 groups were compared. Results: The rapidest growth rate of transplanted tumor volume was observed in blank control group and the slowest in cisplatin group. The growth rate was gradually decreased with the increasing dose of lung-tonifying and expectorant decoction, and the difference in growth of tumor volume among groups was statistically significant (P < 0.05). The cisplatin group showed the highest tumor inhibition rate, with dose-dependent increase (P < 0.05). The apoptosis rate in low dose group was higher than blank control group but lower than high dose group (P < 0.05). The apoptosis rate in medium dose group was significantly higher than blank control group (P < 0.05). The apoptosis rate in high dose group was significantly higher than control group (P < 0.05). The positive expression rates of Bcl-2 and Bax in all groups showed statistically significant difference (P < 0.05), while expression of cleaved caspase-3 and cleaved caspase-9 in 5 groups was significantly different, with dose-dependent increase (P < 0.05). Conclusions: The lung-tonifying and expectorant decoction inhibits the proliferation of tumor cells by inducing and activating the cell apoptosis in treatment of lung cancer with Qi deficiency and blood stasis, probably with good clinical therapeutic effect.
