Changes in wound symptoms and quality of life of patients with newly diagnosed malignant fungating wounds.

OBJECTIVE: This study examined changes in wound symptoms and the health-related quality of life (HRQoL) of patients with newly diagnosed malignant fungating wounds, and explored the factors that impacted the changes in HRQoL. METHOD: This prospective longitudinal study included patients from three hospitals in China who had been diagnosed with malignant fungating wounds. Questionnaires were used to assess patients' HRQoL and their wound symptoms at the time of diagnosis (T0), as well as at one, three and six (T1, T2 and T3, respectively) months following the treatment period. Factors related to changes in HRQoL were analysed using generalised estimating equation models. RESULTS: A total of 162 patients were included in the study. The patients reported low overall HRQoL. In three health-related dimensions (functional status, social relations and mental health), patients reported lower functional status at the time of wound diagnosis (T0), which then increased slowly with treatment over time. A lower QoL was associated with odour, exudate, bleeding, pruritus, a low performance status and the need for the dressing of wounds. CONCLUSION: The HRQoL of patients with malignant fungating wounds exhibited significant changes across different periods. It is thus of great importance to formulate pragmatic, patient and family-centred palliative wound care management strategies.

Effects of microwave ablation on serum Golgi protein 73 in patients with primary liver cancer.

BACKGROUND: Microwave ablation (MWA) is an effective treatment option for patients with primary liver cancer. However, it has been reported that the MWA procedure induces a hepatic inflammatory response and injury, which may negatively affect the efficacy of MWA. As such, the discovery of reliable markers to monitor the patient's response to MWA is needed. Golgi protein 73 (GP73) has been shown to be associated with chronic liver disease. To date, the potential value of serum GP73 in the dynamic monitoring during MWA of liver cancer remains unclear. AIM: To examine the effects of MWA on the serum levels of GP73 in patients with primary liver cancer. METHODS: A total of 150 primary liver cancer patients with a single small lesion (≤ 3 cm in diameter) were retrospectively enrolled spanning the period between January 2016 and October 2018. All of the patients received MWA for the treatment of primary liver cancer. Serum GP73, alpha-fetoprotein (AFP), and widely used liver biochemical indicators [serum albumin, total bilirubin (TBIL), alanine aminotransferase (ALT), and aspartate aminotransferase (AST)] were compared before MWA and at different time points, including 1, 2, and 4 wk following the ablation procedure. RESULTS: Complete tumor ablation was achieved in 95.33% of the patients at 1 mo after MWA. The 1-, 2-, and 3-year disease-free survival rates were 74.67%, 59.33%, and 54.00%, respectively. The serum AFP levels were significantly decreased at 1, 2, and 4 wk after MWA; they returned to the normal range at 12 wk after MWA; and they remained stable thereafter during follow-up in those cases without recurrence. In contrast, the serum GP73 levels were significantly increased at 1 and 2 wk after MWA. The serum GP73 levels reached the peak at 2 wk after MWA, started to decline after hepatoprotective treatment with glycyrrhizin and reduced glutathione, and returned to the pretreatment levels at 12 and 24 wk after MWA. Notably, the changes of serum GP73 in response to MWA were similar to those of TBIL, ALT, and AST. CONCLUSION: Serum GP73 is markedly increased in response to MWA of liver cancer. Thus, serum GP73 holds potential as a marker to monitor MWA-induced inflammatory liver injury in need of amelioration.

The Redox Coupling Effect in a Photocatalytic RuII -PdII Cage with TTF Guest as Electron Relay Mediator for Visible-Light Hydrogen-Evolving Promotion.

A nanocage coupling effect from a redox RuII -PdII metal-organic cage (MOC-16) is demonstrated for efficient photochemical H2 production by virtue of redox-guest modulation of the photo-induced electron transfer (PET) process. Through coupling with photoredox cycle of MOC-16, tetrathiafulvalene (TTF) guests act as electron relay mediator to improve the overall electron transfer efficiency in the host-guest system in a long-time scale, leading to significant promotion of visible-light driven H2 evolution. By contrast, the presence of larger TTF-derivatives in bulk solution without host-guest interactions results in interference with PET process of MOC-16, leading to inefficient H2 evolution. Such interaction provides an example to understand the interplay between the redox-active nanocage and guest for optimization of redox events and photocatalytic activities in a confined chemical nanoenvironment.

Acidity and Cd2+ fluorescent sensing and selective CO2 adsorption by a water-stable Eu-MOF.

A new Eu-MOF was designed from an amino-functionalized ligand and Eu(iii) ions under solvothermal conditions. It is a highly porous, water-stable, and luminescent material, exhibiting pH sensing in the acidic range of pH = 7-3 with selective detection for Cd2+ by an enhanced fluorescence of ∼23-fold against a series of metal ions. Gas adsorption performance shows that Eu-MOF exhibits a high CO2/N2 (15/85) selectivity of 109.4 at 273 K and 1 atm. This performance was superior to that of most reported Ln-MOFs owing to its appropriate pore size, dipole-dipole interaction and donor-acceptor Lewis affinities.

[Analysis of schistosomiasis endemic situation in Yizhou City from 2011 to 2014].

OBJECTIVE: To evaluate the effect of schistosomiasis control in Yizhou City, Guangxi Zhuang Autonomous Region, from 2011 to 2014, so as to provide the evidence for formulating the further prevention and control strategy. METHODS: The schistosomiasis surveillance data were collected and analyzed in Yizhou City from 2011 to 2014. RESULTS: From 2011 to 2014, 770.38 hm² was surveyed for the Oncomelania hupensis snails, and two snail infested sites were found, while no infected snails were found. Totally 3,524 residents were tested by ELISA for Schistosoma japonicum infection, and 38 cases were positive. The positive rate of 2013 was significantly higher than those of other three years (χ² = 15.08, P < 0.05). Totally 432 rats and 28 dogs were dissected and 1,697 cattle were examined by the stool test, but no positive cases were found. CONCLUSIONS: The indicators of schistosomiasis surveillance are basically stable in Yizhou City.

Efficacy of HBV-pulsed DCs in combination with entecavir in patients with chronic hepatitis B infection.

Dendritic cells (DCs) are multifunctional cells that initiate adaptive immune responses. Patients with chronic hepatitis B virus (HBV) infection have reduced numbers of DCs which may be functionally impaired, a defect that may contribute to viral persistence. Autologous DC-based immunotherapy is considered to be a treatment option for chronic HBV infection (CHB). We evaluated the therapeutic efficacy of HBV-pulsed DCs in combination with the antiviral drug entecavir in patients with CHB. Eighty patients were divided into four groups: HBV-pulsed DCs only, HBV-pulsed DCs plus entecavir, entecavir only, and an untreated control group. Patients on combination therapy exhibited greater antiviral responses than patients on either monotherapy. The combination of HBV-pulsed DCs and entecavir resulted in the largest reduction in serum viral DNA levels and the highest percentage of virologic response. In addition, combination therapy resulted in viral e antigen (HBeAg) loss and seroconversion. These results suggest that the combination of HBV-pulsed autologous DCs and entecavir could be therapeutically advantageous for patients with CHB.

[Epidemiological investigation of perimenopausal women in Shanghai].

OBJECTIVE: To explore the cognitive level and the mental status of the patients suffering from perimenopausal syndrome in Shanghai, and to identify the traditional Chinese medicine syndrome distribution feature of perimenopausal syndrome. METHODS: The cognitive level of the perimenopausal women was evaluated by using general living problem questionnaire. The mental status of the perimenopausal women was evaluated by using self-rating depressive scale. The traditional Chinese medicine syndrome distribution feature of perimenopausal syndrome was identified by using traditional Chinese medical symptoms questionnaire. RESULTS: A total of 634 perimenopausal women finished the investigation. There were 74.76% (474/634) patients who knew little about the perimenopausal syndrome; 77.29% (490/634) patients had a depressive tendency; 8.36% (53/634) patients had depressive disorder. There were 72.40% (459/634) patients who had the symptoms such as susceptibility to anger and restlessness, restless sleep at night, thirst with dry throat and bitter taste, and all these symptoms could be classified into hyperactivity of heart and liver fire syndrome. CONCLUSION: Patients suffering from perimenopausal syndrome know little about this disease and mostly have depressive tendency, and the major traditional Chinese medicine syndrome pattern is hyperactivity of heart and liver fire based on the chief clinical manifestations of the patients.

[Clinical study on relationship between memory quotient, estrogen and Chinese nourishing kidney herbs in perimenopausal women].

OBJECTIVE: To explore the memory quotient and hormone level in women with perimenopausal syndrome and healthy women in perimenopausal period, and the effect of estrogen and Chinese nourishing Kidney herbs (CNKH) on memory. METHODS: Fifty-six women of perimenopausal syndrome were treated with estrogen (n = 24) and CNKH (n = 32) respectively. The changes of memory and estrogen level before and after treatment were determined and compared with those in healthy women. RESULTS: The memory quotient (MQ) and estrogen level increased and follicule-stimulating hormone (FSH) level decreased significantly after treatment in both groups (P < 0.01), these parameters approached to those in healthy women. The difference of therapeutic effect between the two treated group was insignificant (P > 0.05). CONCLUSION: The decrease of memory is related to the lowering of estrogen level, CNKH could improve the brain function and enhance memory.
